Since there are a lot of comments about the X3D Core affinity: I know that I can manually fix it with tools like process lasso but that's no adequate solution. Only if we point out issues like that, they will be fixed eventually. Publishers, AMD and Microsoft have to update their Games/Windows/BIOS/Chipset so it works out of the box. You have to keep in mind that the average gamer probably has no idea about things like that and that he might not get the full performance.

For the 7950X3D you need to make sure your Xbox app and Microsoft store apps are all updated. Once you do that you can hit the shortcut Windows Key + G and it comes up with the game bar. In the settings wheel in game bar you can select this is a game and the game will now set to be ran only on the Vcache cores. I have had to do that with only new games that I guess haven't been added to the list in the driver yet, but this is the way to fix it.

400Watts CPU + 450Watts GPU = 1HP AC just to counter the heat. :D

Cats everywhere will love sitting on top of pcs running this. The ultimate cat warmer.

It's impressive how much less the 7950x3D is consuming while almost at the same performance

This feels like 14nm+++++++++++ all over again. We're on the 4th edition of this CPU.

Gotta also select "remember this is a game" on the x3d in gamebar settings

Last time I was that early, CPUs didn't double as furnaces.

7950X3D: "look what they need to mimic a fraction of my power!"

KS = building your home near a river and diverting waterflow to your loop. Just make sure to install those fish barriers.

the 7800X3D still reigns in gaming ;-)

Enabling delidded processors feels like a must, to keep temperatures under control.

A CPU that shouldn't exist. Period. Thanks for testing!

This cpu is a joke imho. 400W to barely beat AMD. wow. 😮

Finally, an informative and smart review. Thanks.

Good God, Roman, your "script warmer" is gorgeous!

No Mr Bond, I don't expect you make a video without your script!

I'm reminded of the Preshott socket melters, Netburst again

This power thing looks exactly like the problem last time with mainboard defaults and autos being wrong and applying too high voltage. Did you check the actual voltages vs requirements/spec?

it would be nice to see what this KS would look like with e-cores turned off and or maybe HT off as well, power would certainly be more acceptable but would performance stay the same?

This CPU will make Gamersnexus's Steve create a whole new methodology about CPU coolers, and 100+ new charts to fully test this CPU including: "Can this heat my room in Winter?" "Can this heat a room in north pole?" "Will it cause a blackout in Germany?". Stay Tuned for GamresNexus Review!

I have the 14900k, I love it even though its hot. But this is why competition is great, and why I'm thankful AMD is making good cpus, competition only helps us get better products.... Although in this situation i wouldnt call the ks better...

Apparently the thumbnail shot turns the video sponsor into 14900KS requirement.

Hey Roman, regarding the 7950x3d vs 7800x3d discussion, couldn't you have simulated them by deactivating the non X3D cores or just by using Process Lasso to force the program's threads to utilize the X3dD cores? I'm sure there's a valid reason, but I'd be curious to better understand!

The price to performance consideration has led me to choose AMD CPUs for every system I have built, dating back to the Phenom II X4 965 Black Edition. I have gone back and forth between Nvidia and AMD graphics over the years, but have always run AMD processors.

With 5090 soon to come and new Intel CPU's I surely need a contract with the city general power grid or i'll rent an warehouse near to an industrial power plant

I've actually run into some cases where windows scheduler gives up trying to schedule stuff properly on the hybrid-core intel chips and then just starts shuffling threads around wildly at times, causing bad stuttering. This usually happens with a pairing of game & cpu when the game simply has more heavy threads than physical p-cores, at which point I start seeing stuttering, etc. This doesnt really impact the higher corecount chips because most games only have around 8 heavy threads currently (some do exceed that, but they usually aren't fps-critical games - its stuff more like AI-heavy turn based strategy games during end-turns), but it is very noticeable on the lower end mobile chips with hybrid core architectures which might have only 4 p-cores (or even less). Even games heavily optimized for old hardware that can run just fine on pure e-core cpus (ex, the N100) like warframe can suddenly experience intermittent really bad performance stutters if you put them on a device that has a cpu that is better on-paper like a 2p+4e core chip, purely because windows scheduler starts panicking and throwing threads everywhere since there are not enough p-cores for the game when if it kept the threads in place on whatever cores they were already running on it would be just fine.

I remember seeing something somewhere from someone about limiting the clock speed of the non X3D cores so that the "fastest" cores are always the ones with the 3D V-Cache

That AMD power saving is Epic levels of awesomeness!

if you look to the left of gaming benchmark chart, you can see ryzen power consumption, easy to miss among intel bars racing with fps bars

I am curious as to what was used for cooling... Was it done with an AIO, and if so which one? Not many reviews showing over 300w cooling capabilities for an AIO...for 400w it almost feels like some custom cooling is going to be required.

Back in the day if you recall the extreme editions used to give 5 year vs. 3 year warranties. I think it's nice that for the extra money you get better warranty. That alone is worth a lot for the high end cpu stuff as the risk of them cooking themselves is higher. If it wasn't for that warranty extension I would have had a big problem when my 990X died, but with its warranty Intel just sent me a new one. Can't complain about that.

This is basically Intel doing a cover of the FX-9590.

Amd learned his lessons from bulldozer, Intel forgot the ones from pentium 4!

Enjoy your videos and look forward to the next one on the KS. I'm really curious how the KS performs power consumption wise when power limited because sometimes the unlocked power causes the voltage to spike. When you do the next video hopefully you check the stock 253W power profile.

42,650pts in r23 on my 6.2ghz overclocked 14900k @ 360w. 💪

In Brazil this CPU is a complete nightmare unless you are rich and/or have solar panels and a big AC. Very happy with my 7800X3D with only 50-60w gaming

That cat is absolutely adorable ☺️

I'm guessing the video is recorded in 30fps? The game footage at the end and the to camera footage is incredibly chunky is all and the game footage has been scaled back to the recording frame rate?

Curious how well binned these are and how well they respond to voltage tuning. Just from an academic standpoint. I don’t need this many cores anyways (not on my gaming machine, do dev work on my Mac) but just would love to know.

Mostly for the spectacle's sake, I'd like to see how this new KS would perform delidded + direct die contact frame + heavy duty water cooling loop. Seems like the delta between a 14900k vs amped up 14900KS would be interesting. For shits and giggles, I'd also like to see a 7800X3D + 7800X3D delidded + direct die contact frame + water cooling loop, plus some very basic modifications in BIOS, mostly as it relates to curve optimizer built in _(ASrock has a good one)._ I'm interested in the spectacle of what _'could'_ be a typical daily but at the extreme end. Not important, but I'd find it interesting.

Yeah, testing CS2 in 4k with 4090 at 99% load is a VERY nice test for the CPU. Keep up the good work.

It would be amazing if we came full cycle and went back to direct die contact like it was on the Athlon XP CPUs.

Maybe you already tried this but for the 7950X3D sometime you have to update the Xbox app through the Microsoft store, to get newer games to play on the X3D cores, and you can always force the game to be on the X3D cores by checking the box under the xbox game bar app general setting for "remember this as game" I have to do this for most emulators . 🙂

Intel are campaigning for 420mm Aio coolers. 15th gen are going to cause power outages.

Came watching for the CPU, kept watching for the cats

der you are by far the best tech youtuber in the oc part but can i ask you a little favor??can you make a video this again but with the cores disabled?they say if you disable the cores you get more fps i dont know if they say it for ecores or pcores

Roman, would that deal be for extreme laptops, where they use desktop cpu's with liquid metal ?

Your cats will love the heat from this CPU

Can't wait for Alienware 14900KS delided, with intel stock cooler on top 😉

Great to watch this with you!!!

I know it's weird, but I'd be curious how well this undervolted as much as how it overclocks. Can you get it to use the same power as a 14900K stock with no performance loss?

Be aware that Asus has special settings that ignore Intel limitations, this can explain the high power draw. Jay did a video about this.

I wonder what the future of PSUs is going to be....with more powerfull draws

I’d really like to see some other real world testing. How about DaVinci Resolve and SolidWorks?

Finally, a spiritual sucessor to the FX9590 😅

14900KS is a 13900KS TI

EU tends to ban everything non-eco nowadays... this cpu would be prime example to do that in the electronics branch :D

Could we see a test of the 80w mode against k or kf? Would better interesting to see the silcon quality difference.

What cooling solution was used in this test? 360mm aio?

Sick

I've seen Intel 13900K/14900K users on Frame Chasers and Reddit say they're having silicon degradation on their chips. They said that they can't hold overclocks anymore and in some cases have complete CPU failure after ~6 months. Are any of you experiencing this?

I'd be interested to see how much you can undervolt the 14900ks and achieve stock clocks. If you can get a -0.1 thru -0.2v offset and still achieve stock clocks, that will bring down power consumption and heat a lot. I know with my 13600k I can achieve a -0.225v offset and still run stable at stock boost clock speeds. This isn't how I have it setup though, I have it setup achieving the maximum overclock on stock voltage of 1.375v. Which I am able to run 5.5ghz on all p-cores, 4.3ghz on all e-cores and 4.9ghz ring cache.

I will stick with my i7-14700KF for now. Thanks for the review

Cpu alone using more than my 5800x and 6600xt combined. Not when both are oc'd ofcourse but damn

This just cements the fact that AMD is the leader in efficiency. 400 W just to be a few percent faster than the 7950X3D is crazy!

So does this mean. That this CPU in a test bench setting . Was on the edge on maxing out at a 360 AIO??

From power to POWER to beat power.

I’m happy with my 7950x3d. Between that and my 4090 my psu only goes up to 300 watts under load.

Intel back to their 2-3% ipc gains… over clock them to keep up, power and heat be damned! So 400w stock, I wonder what OC will bring that up to, 600w?

I would have loved to see it on a full custom loop

I've been tuned out for 6+ months. When did the Dr. Evil thing start?

u just need to change cpu affinity on task manager or process lasso

14900ks buyers are enthusiast. No one buying a 14900ks is buying from an SI so that delid warranty is pointless. The warranty should have been for the consumers not for businesses.

I'm curious to see how efficient this chip is because of the bin, when power limited and undervolted.

I bought a 12900KS a year or so ago, but through a series of unfortunate events, I needed to replace my main board. I bought a new CPU just to keep things on the latest gen since I had to tear it down anyways. I bought a 14900K this time. It was pulling over 300 watts with nothing but an xmp profile loaded. It may not be everyone's cup of tea, but I like it.

So happy to run a 7800X3D for 5 months now on my gaming setup.

If they are going to cover delidding under warranty, they are asking for trouble. It is a delicate operation and it doesn't always go well.

That overclock on the 14900KS was insane, oh wait, this is stock...

I come for awesome tech stuff but stayed for the cat

Did you watch that recent video by Dave's Garage? showed his Threadripper hitting 1000W :)

0:38 don't you dare to cut her out like that again!! ❤

5:06 how do we know it is delidded and not just lidless from the manufacturing?

New BULLDOZER 🤣🤣

Dude, just call it 13900KISS. Sheesh!.

I think intel did this for two possible reasons: 1. 14900KS is not meant to be used like this. I believe it is solely for liquid cooled/custom OC builds, possibly having better IMC for higher RAM clocks, essentially this chip being an unlocked beast with lots of headroom to play with as a last send-off of a monolithic design. 2. Possibly they made this chip in such a power-hungry way so they can compare their next-gen to it in terms of insane new efficiency saving when they introduce next architecture later this year/q1-25.

So this is why Jay got that quad 560 water box from Singularity.

I'm starting to think Intel has performed necromancy on the NetBurst architecture.

If the 7900x3d had that many cores it would smoke and still be under 400w I bet 😮

One time runs on r23 hits 38k on multi core with my 14900k. In a 10min run, I get 35.5k. It stays pretty consistent after a few runs. But, I have the watts set at 275 max and it still throttles down to 4.9-5ghz, but with better temps vs when I had a 135mm tower cooler.

I run my 7950X3D w/process lasso. It’s fully configured for everything I play, but that seems to be the only way around it trying to play some games on the wrong CCD.

Might honestly be one of the worst CPUs I've ever seen.

Fluffy cat!!! And that cpu make a good butt warmer for the cat :)

Why do the odd step with delidding when they can simply not add the heat spreader? Makes no sense to add extra risk and work.

In Christopher Walken's voice: MORE! MORE POWAH!

Intel totally lost it 😂😂😂😂

Thats really poor performance. No wander so much people buy AMD these days.

I have new settings which I am using for my i9-13900k and i9-14900k. I don’t like the uncertainty of undervolting so prefer working with power and clock limits. With these settings I got a couple of FPS BETTER on CP2077 and Forza Horizon Benchmark, went from 99th to 98th percentile on PC Mark Extended, passed the Time Spy Stress Test, Time Spy was within a whisker of the average for my hardware, Cinebench R23 finished between 37-38000, CPU-Z, Intel Diag tool and Prime95 was stable and < 90 degrees. MCE off, PL1 and PL2 limit to 225, limit P-core boost to 5.3 GHz and E-core boost to 4.0GHz, and use balanced power profile in Windows (although I do disable core parking to keep system highly responsive). Oh and just XMP on the RAM. I didn’t change LLC values. With these settings, you should have no stability issues, be able to run on an air cooler like the NH-D15 (what I use on my 3 i9 13th/14th gen systems) and will barely notice any performance changes in gaming or productivity.

Guess I'd better de-lid and build a custom water loop sometime this year...Didn't know my future i9-14900K would draw 400W before I bought my 250W air cooler.

"extreme" is a really odd way to spell shit
