@@seeibe it seems to be mostly aimed at gamers - which I don't understand: who needs 16 cores and 32 threads to game? - and that happens mostly on Windows. I guess they figured the Linux gaming community is not big enough to worry about. As for software engineering tasks, the 7950X is a better bet.

@@treyquattro it’s to milk impatient gamers who don’t know any better. The only realistic excuse asides from having money to burn is so they can stream and game on the same rig, then edit afterwards too. Even then, the best streamers run dual PC setups to avoid performance drops while gaming.

@seeibe Жыл бұрын

@@treyquattro I wonder. Most benchmarks are focusing on a single program, which works well for gaming or blender, not so much for software development. You typically have many workloads running at the same time. If some of those workloads are cache bottle-necked, a 7950X3D would make more sense, assuming the scheduler is smart enough to put those workloads on the right cores.

@treyquattro Жыл бұрын

@@seeibe the scheduler doesn't have enough information to know which core/CCD to give work to, especially since the Zen4 architecture is homogenous apart from this one new change. Productivity tasks are typically I/O bound - like compilation - more than CPU-bound tasks which can take more advantage of locality of reference of data. That's why e.g. Threadripper with 4 times as many memory channels and 5+ times as many PCIe lanes smashes mainstream computing on productivity tasks.

It depends on what you want to do. Higher over all clocks in the r9-7950x but much higher power use. I think they've maybe tweaked the newer cpu to use less power (even if you under clock the 7950x). Most benchmarks show they are not much different. As said by another it may be worth just waiting for next series cpu before you do. I suppose unless you can sell your old cpu and get a good deal? I somehow doubt that right now though.

It should be possible for a program to self optimise, you can query cache sizes at runtime, but the system libraries and OS kernel will need to pass thread specific info. I can imagine best results putting a gang of worker threads onto CCDx3D which use the same data (especially read only), while management & helper threads running with other data can use the high frequency CCD. Still I doubt many developers will want to optimize for this rare case.

Thank you so much for this video, after GN published a review about how some special sauce was needed on windows to make the 7950X3D run at its best, I was a bit worried about how it would run under Linux, since that's what I use for productivity. Glad to see that things are running smoothly! Also, could you perhaps elaborate further why you think that 4 DDR5 DIMMs don't make sense on AM5?

@Winnetou17 Жыл бұрын

Regarding why not use 4 DIMM sticks on AM5, he detailed it in some previous video, I don't remember which, though if you really don't find it, I can search it. The idea is that it's support is not that good (and, surprisingly for me, not on Intel's side either). With 4 sticks, you have too get down to slower speeds, like 5200, even down to 4400 MT/s if I remember correctly.

@TheExard3k Жыл бұрын

If you can live with lower clock speed on the memory, 4xDIMMs will run fine. But don't expect more than 4800MT out of them. That's why Wendell and most in the L1Techs forums agree that 2xDIMM, without going 2DPC configuration is the sweet spot for consumer platform, both Intel and AMD. We only have two channels after all and the memory controller doesn't like lots of big non-RDIMMs.

@skilletpan5674 Жыл бұрын

There's been several youtubers that have made videos and commented on why 4 sticks are a bit crap. It seems to be the same issue as the old socket 2011 boards when you populated all 8 slots. It usually comes down to instability in the chipset/memory controllers. 2 slots are easier to synchronize than 4.

@TheExard3k Жыл бұрын

@@skilletpan5674 2 DIMMs per Channel (2DPC) is a nice feature, but puts the memory controller under much higher load. Even server platforms can't keep up high clock speeds when using this with high capacity DIMMs, although RDIMMs negate most of the drawbacks. Thus: 2x DIMM for performance, 4x DIMMs for capacity. I'm running 2x32GB for this reason until we get proper 64GB DIMMs that allow for higher than 4000/4400MT on consumer boards

@finestPlugins Жыл бұрын

AMD guarantees 3600MT/s when all slots are populated. I've got 5600CL36 modules and 3600CL30 is all I get on auto from my motherboard (with EXPO). I haven't bothered trying to tweak that yet.

Considering you can change scheduler behavior from user space already, it would be best if you could just give hints to the scheduler on which core to use through environment variables rather than change settings in the BIOS. Short of that something like adding "gamemoderun --prioritize-3D-cache" to a game's launch options would also be a better interface than rebooting and changing BIOS settings for Linux users.

@Hugh_I Жыл бұрын

you should be able to pin games to the V-Cache cores with "taskset -c 0-15 " (assuming lower core numbers are the V-Cache ones). You could probably just put that into the custom launch options in Steam for any game that benefits from that, and of course do the reverse (taskset -c16-31) for games that want high clock speeds. You can also change that on the fly with a running process, good to determine what benefits the game more.

Was originally planning on building 13th gen Intel but that was enough to nudge me over to AM5. Also very excited to see how future VCache chips look. The 7950X will probably pull it's own weight until late into AM5's lifecycle, so I'm hopeful for what our upgrade options will look like when the time comes to swap it out for a newer option. CPU tech is so awesome right now, and it's only going to get more exciting as Arrow Lake and Panther Lake enter the arena. 👀

When I game and watch the CPU-loads then I notice that always first the first 8 consecutive threads get put to work and only when more threads are needed the other threads get to work. So it looks like Linux has some awareness of topology and keeps the same tasks on the same CCX/chiplet but that is my layman guess based on what I observe.

I'll wait maybe 5 more years. My current workhorse I built in 2018 and still going strong with good performance. And I still have my Phenom II machine, most of which was built in 2010. The 12 volt rail got crispy back in 2018 so I replaced the motherboard and power supply for 100 bucks. I've never been "bleeding edge", as I need my machines to work out of the box with what I have been running. I'll let the whales buy into this new tech, and I'll grab it when everything's been smoothed out and at a much more reasonable price. I just can't see building something for several grand and have to dump another 200 bucks to cool a processor with liquid, when I don't run the latest games at 4k or render 4k video in a production environment. I play games at 1080p, do character creation, draw and post-work rendered images, and model stuff in Blender and Marvelous. I don't need a 7950x3d and 64 gigs of memory to do that. Probably won't even boot into a Linux Mint stick with that setup, without customizing it with a bleeding edge kernel. My 1 year old laptop can't even boot on the latest Mint version.
