Until 11/23/22, code 'THISISFINE' will give you 10% off the GN store! The best way to support our work is through our store: store.gamersnexus.net/ Watch our video about the cool hardware feature on the AMD RX 7900 XTX reference video card: kzfaq.info/get/bejne/bsuDraeHxtynXYk.html

It's very special when you get 15 minutes from someone like this! Look up his resume to realize he holds over 130 patents, and is the main designer behind many innovations in the computing space. Thanks GN for giving us some time with the man behind it all.

I'm loving these engineer discussions. Plenty of people cover the consumer-facing side of hardware, but it's so cool to see what goes into them behind the scenes. Really makes you appreciate all the hard work that goes into our FPS!

The amount of PR training that these guys go though is insane. Engineers such as him know very well what RDNA4 is going to look like and possibly even RDNA5, but to make sure one only speaks in "released product" terms takes a lot of holding back.

With Nvidia's insane pricing this is gonna be my first AMD card

Man Sam is just an amazing presenter and engineer. He really does a fantastic job of getting the point across in layman's terms.

I love when we get direct talks from the engineers! Thanks GN for the coverage as well as for all of your other informative and deep, "engineering"-focused reviews! Hope you can make more videos and insightful reviews of PC components and products for years to come!

This is what our investment into this channel gets us. These interviews are great, Steve has developed some great interviewing skills and Sam himself presents his great knowledge in an equally talented way. Between the both of you, this was a fantastic interview. Great watch 8)

so you're telling me the only reason why we don't have a 4 core 13900k right now is because of this amazing man right here... Sam is truly an incredible down to earth engineer. I'm super in debt to you

When AMD was presenting RDNA 3 you could hear in his voice, though calm and soft, how excited he was with what they were coming up, like he was really trying to convey how cool all this new approach actually is. Too bad the audience seemed to have missed that, or at least that's how it looked like from the KZfaq stream.

every time I learn more about CPUs I'm amazed that computers work at all. Just the sheer amount of tech in this chip that fits in the palm of a hand and we make like thousands every day.

Sam making the chiplet approach seem like an absolute no brainer in only 15 minutes. So awesome

I hope he realizes how much we appreciate him taking the time to do this. This was AWESOME!

I read "How amd is FLIRTING WITH NVIDIA with RDNA3" and fear the worst.

Nothing more beautiful than engineer to tell you how things works and what they did, not to send some marketing waxed boy to tell you basic things and that's about it.. I love things like this, community is really interested in a knowledge which this gentleman and other engineers have, this is the best way to see how much people respect their work, passion and intelligence which they have.

I will be brutally honest with you, guys. This is one of the best videos to ever land on Gamers Nexus YT channel. Kudos to you for getting an idea to put an AMD engineer in front of the camera and ask him about the "kitchen". And kudos to Sam, who has a rare talent of being able to explain complex issues in a way that is totally digestible to an average PC hardware fan. Amazing stuff, guys!

Sam is absolutely right about engineers wanting to work on the cutting edge. Back when I was a product engineer for a Telco equipment company, I was excited to work on the IP over wireless tech. You guys know it as WiFi. But the other part of my work was dealing with PSTN, which is fixed telephone lines carrying 56k modem stuff.

Top tier content as usual from GN! Always interesting to learn about the design challenges that the engineers face and how they overcome them with innovative solutions.

I think this reflects what has bring AMD to a new "golden" era, it's not about working hard, you need to work smart. Something insanely true if we see the ARCs GPUs.

This is exactly what I was hoping to see more of. Thank you to Sam from AMD for the presentation, as well as the GN team for this continued emphasis on the work that goes into the products.

Man, that vastly simplified, imagine just how complex these devices really are! I mean I've been in IT for 30 years, and I am always just amazed at how they design any kind of silicon (or plastic now) lol Great content, thanks. =)

I know Sam a little. He’s a good dude. Did some mtb racing a decade ago with him. He’s an animal!.. It’s been a while but I remember him speaking about chip tech in general. He’s a damn smart guy. He’s responsible for lots and lots of patents. Good to see his work being implemented. I wouldn’t doubt AMDs success being partly to Sam’s work with chiplet design and integration. Great to listen to the design details! Keep up the great work! 🍻🍻

The next gen Radeon gpus are turning out to be extremely interesting. Hope it's a good product, regardless of the horrible price market.

You can see that Sam's clearly passionate about this and knows a lot a lot about chipset design. He's truly a remarkable person and I loved seeing an in-depth yet simple interview with him. Hope to see more content like this!

What I love this channel for is the actual little to no editing with that kind of stuff. Your videos guys are just authentic. It's not easy to pull off, in my opinion, so big respect from me.

I'm sure it would be asking a lot to get more time than you already did but I could see an hour long segment just devoted to discussing the various aspects of this design. More than anything, I'm just keen to see how it performs in-practice.

You can tell he fought for this simply by how easily he can explain it in the simplest of terms. He clearly has experience selling this idea to bean counters who already knew nothing about the technology or the manufacturing process beyond timescales & costs.

A couple of obvious things from this presentation that AMD is likely going to do in the future and it centers around re-using more chiplets across more product lines. 1) Spin off the PCIe, display interfaces and encoding logic on their GPUs to their own chiplet. This single chiplet will be spread across their entire GPU lineup and even serve as part of the desktop IO. On desktop the memory controller die which also contains the basic links to the CCD. 2) Common dies for stacked cached that are used on the CCD on server processors and MCD on graphics. This isn't about performance but economies of scale as it permits AMD flexibility in how they allocate these cache dies. 3) Common Infinity Fabric link between CCD, FPGA, GPU and specialized IO dies. This dives into AMD's semicustom side but if a large customer *cough* Microsoft *cough* wanted say a four CCD and two large FPGA dies in a SP5 package for a server, AMD can leverage their existing die portfolio and quickly validate a custom package for release. I think much of this first wave of AM5 and SP5 products are purely a stepping stone in their strategy. I strongly suspect that AMD is leveraging the same Infinity fabric interface between Zen 3 CCD, Zen 4 CCD, the socket AM4 IO die and socket AM5 IO die. The reason behind this strategy is that AMD could have launched AM5 products leveraging the Zen 3 CCD if it made sense to launch a DDR5 based platform earlier. Similarly if DDR5 was not ready in the market, AMD could have launched Zen4 on socket AM4. Essentially AMD had an insurance plan on how the market move and always get a new product out to continue competing. Not covered in this presentation is how much energy it takes to move data across various wires. While chiplets provide lots of flexibility in terms of design, they require more power than a monolithic design. I would predict that in the Zen 5 generation, AMD is going to replace the traditional wire based packaging with a full interposer or EMIB-like technology to reduce wireless lengths and drop power consumption in this area. AMD has given a strong hint that this is the direction they're going by some of their HPC parts based around CNDA will include a Zen 5 CCD die(s) in the same package.

Pretty excited for these GPU's on mobile going forward, love these types of videos

This is genuinely one of the coolest interviews I've ever seen. Thank you Steve (and team!) for always pursuing and sharing these opportunities

Adored tv was right again, and he was stunned by the realization of how far ahead amd is at this point in time. I was stunned as well. This will be a huge game changer.

Please please keep making these. I love these videos more than anything else.

So excited for benchmarks, been putting off building a new rig to finally upgrade from my 5 year old 2200g build without a dGPU for months now until we know what AMD truly has to offer with RDNA3...

I really love it when you let engineers talk about the design. You know he really knows about his design by the moment the question is fires his eyes shine and immediately knows what slide to show

I really admire the actual team working for AMD. Has been a fantastic uphill recovery since the dark ages of Hector Ruiz where I would every day expect to hear of AMD bankruptcy. Well done!

I like how he pointed out that the engineers don't like to port the IO stuff and much rather work on the "cool" stuff 😁

These are my favourite videos you guys do, where you get to talk to the people behind the tech and get a sense of their vision.

You guys have really been crushing it with your industry interviews and hook ups recently. Great job.

I could listen to him talk about this topic in detail for hours. Happy for the 15 minutes you managed to get. :)

Man. You gotta consider that a hell of an interview catch. And from AMDs perspective, they've got an engineer that's personable enough along with a mastery of the engineering to make this interview a big win for them too. If nothing else, getting information out to a few hundred thousand people capable of understanding it (at one level or another). Good job.

THIS is what I love to see! Let the engineers speak! I would watch an hour of this with rapt enthusiasm - really wish we could get an uncut version of the full presentation. Love hearing about all the ways the engineers are pushing their designs and the technologies they have access to in new and different ways to achieve their goals!

Wow...that sure was interesting. I could definitely spend hours just listening to the various design decisions being made to bring this design to fruition. Well done again GN!

I wonder which was the last question you didn't have time to ask Sam. Amazing interview, this kind of coverage is something that is hard to find among the tech press, focusing on technology and not only on raw performance on synthetic benchmarks. Thank you guys!

It's presentations and interviews like this that provide the real roadmaps for platforms and its always a treat to see them come up, thanks for getting some time with the man himself GN!

Steve and Wendle, taking PC hardware breakdowns to a whole new level.

That was fantastic, love the insight. If they can have a "Zen" moment with RDNA, it'll truly be great for gaming. It'll even reverb through the next console cycle likely as well.

Thanks to Steve and the team for providing this kind of in depth coverage. It is good to get some actual in depth info beyond the usual benchmarks and marketing speak. Great job!

Great interview, always great to learn about some of the concepts that these engineers come up with, and it was great that the language wasn't so technical I couldn't follow along.

I would have loved a two hours video like that. It's so interesting when you can interview the biggest brains of a company :D

Love listening to engineers, massive respect to him for giving us a look behind the scenes about this stuff even if it's AMD allowing him to speak to help show things. Super cool thing to do occasionally and everyone wins. Hope he doesn't mind having to do this speaking stuff especially with all the PR training they put people under for good reason, he's a great presenter and we really appreciate it

always a treat to hear from the mind behind the more interesting and impactful designs and processes, many thanks to steve and GN team for grabbing this fun little q&a!

Thank you for making this video and to Sam for taking the time for it. This was the most interesting video about RDNA3 I've watched so far and got me to appreciate the technology that goes into it even more.

This is great, more interviews like this please! :)

Incredibly interesting to hear some background perspective and it was very digestible, even as someone that doesn't have as big of a clue about the details behind this kind of hardware. Sam seems incredibly competent and makes me hopeful that there will be many more great technological advancements from AMD with people like him working on it! Looking forward to more

Great video man! And it's really great to have a man from inside with all the experience to tell all these things.

GN is killing it with these interviews! Well done Steve and crew, I love the trajectory you're going in.

This is so cool! I loved the discussion you had recently with Intel and Nvidia but this was something different. Its insane to think how much this one person shaped the current CPU space and will also maybe or hopefully shape the GPU space. Thank you all for recording this interview. I am super excited for more. I hope Intel, AMD, Nvidia and others see the benefit of these kinds of discussions and will give you more opportunities to bring us more "behind the dies" content!

I'm glad they decided to share some of this background. I know there's a tendency to keep everything a secret with technology companies.

This was awesome, you were right at the beginning! Thanks for sharing, cant believe this is free^^

Loving those engineer discussions! My lingering doubt about the chiplet approach was always the interconnect bandwith bottlenecks, so interesting to hear how they work around it!

He could make a 4 hour presentation and I would watch excitedly ... can we get more of this ? ... Sam ? Steve ? Please?!

I'm guessing Sam is always the smartest guy in the room.

I love how Steve is always way up on the conversation - understanding everyhtin and asking pertinent questions. lets the video go to great places.

Amazing video. I’d love to see more. Is there a longer video in the works or perhaps the original presentation video available?

Great! very informative thank you

I literally always wait for your video!!!

Loved this discussion, great interview, Steve, thank you!

This was so good I actually got to the end & was sad it was over, hope to see more like Steve mentioned!👍

Sam strikes me as a smart and capable guy who might not be aware of just how many hundreds of thousands of people are going to view this video. He's about to become quite a bit more famous among AMD fans

Seems AdoredTV's guess of about 1000 on a wafer was correct. Also looking at the slide around 8:55, when fabbing a 16 core chip, taking 16 chiplets as a 100% value it seems chiplets are also scale to larger designs better than the monolithic approach. The monolithic version going from 8 cores -> 16 cores is a 2.1X increase in cost, but in the chiplet version it only costs an additional +0.25X to go from an 8 -> 16 core, that's not just a little saving that is significantly better.

Excellent video, it was interesting to see the engineering point of view of those products design, i hope to see more of those in the future keep up the good work!

That guy's time is valuable. Thanks for stepping up and answering questions Mr. Naffziger. And thanks to Gamers Nexus for providing the content. Great job Steve.

I am extremely interested in this generations performance and in how they iterate on this.

Thanks, It's hard to get any kind of accurate information on anything these days on the internet. I appreciate your channel and candid reporting.

this stuff is so fascinating. great work with this interview, would love to see more of this!

I really can't wait to see end user benchmarks, I really hope it's not a disappointment. I'd really like RDNA3 to be my next upgrade.

Man this is great insight on where amd is going for the next 3 years (or more). It lets me know how to budget for servers and desktop performance and what I need it for. This is one of the few videos you guys have that is bookmarked. Good stuff. This guy had to hold back talking, but it put out some good nuggets|vcabulary of info (that I can search in the underground).

Amazing content. So happy y’all are getting opportunities to work with key industry players. As usual, high quality output. Bravo.

That was great interview and Sam did great job breaking down their tech.

I understand that he may not be able to talk about it, but it would have been really interesting to hear him talk more about slicing up the graphics logic into several separate dies. He said that the bandwidth requirements would be too large, but is it something that they are working on for the future?

I wonder if the MCDs offer such a benefit that they obsoletify HBM. With that many memory channels and that much cache acting as an accelerator for the GDDR, the total effective memory bandwidth to the GCD may be greater than with HBM.

Thank you for your time, Sam!

quality interview. great questions Steve!

Very interesting video, the chiplet approach looks hard to implement in GPUs but appears to have massive benefits. So far it has apparently allowed AMD to stay below $1000. I wonder if the RX 7800XT will use chiplets too.

F'ing TRAIL BLAZERS! Sam and GN both, in their own arenas. Bravo to all involved!

Thank you for a great interview!

These technical discussions are fantastic! Love to see this.

Hope everyone at Gamers Nexus has a great Thanksgiving.

When I was a kid in the 1990s in Austin I had a friend whose dad was a senior engineer at AMD (they had a Fab here forever) and on his office wall he had like a 5' by 5' schematic of a chip he helped design earlier in his career. It was so amazingly dense and detailed I couldn't imagine how human brains could come up with it. Looking back now I wonder if it might have been a 29k chip. The house my friend lived in was very very big let me tell you.

Never stop doing these, pls!! We need more engineer interviews.

Great thanks for this post-presentation interview. Please keep it up if possible.

It's great to hear from actual engineers. It's much more interesting and gets me more excited about the products than the normal corporate nonsense they put out does.

What's wild to me is that for so long, the progression was to move more and more things onto the main die with the processor (even more so with mobile devices), and now we're finally going back in the opposite direction and breaking the big monolithic chip into pieces.

I'm actually understanding the basics of chip manufacturing! Thank you all for the in depth knowledge!

Wish you could have had more time, so much to learn from this. Excellent questions from your side!

I truly am cheering for AMD to be successful in both the CPU and GPU space. We need a strong AMD to bring out the best in the competition. For myself, I can't leave Nvidia because a lot of software is clearly superior on Nvidia because of CUDA. I use almost the entire Adobe suite of software and they are heavily CUDA dependent. I know that AMD is stretched thin and would rather focus on the bigger markets like gaming. But if they could make their GPUs fully competitive in the markets like video editing, it would make me consider AMD GPUs. I wish I could use a PC only for gaming but the reality is that my daily work also needs a fast GPU. Time is money but more importantly, longer times is greater cost. That said, go AMD! I'm still on Ryzen (rocking a 5900X system) and will be upgrading to the 7900X. But right now, I'll stick with my 3080 for now.

7900XTX for Me!!! Cmon December 13th!!!

The content and the technical prowess you guys have. Is amazing but I really tune in for the hair!!❤❤

Thanks Steve- Learned a new word this morning - as·ymp·tote - a line that continually approaches a given curve but does not meet it at any finite distance.

I think having you and AdoredTV here to discuss the chiplet approach would have been awesome. He did a video too trying to look at why AMD did the chiplet approach the way they chose to, and what it could mean in comparison to nVidia. Very interesting to see where this goes in time, if they do something like move more onto the smaller chiplets or not.
