AMDs website says $699 and not $399 for the 16C parts.Question.. Why is a 16 core 4004 EPYC(4.5 ghz) + motherboard($399+$299 $698 total) close to the price of a 9950x(4.3 ghz, $542) and the 4004 runs faster ????
I got my answer. The 4004 is Zen 4, not Zen 5. Its a ways back in this thread.AMDs website says $699 and not $399 for the 16C parts.
Interesting thing - there's 2 new skus at the bottom: 4-6 cores, 2-4 CUs, 50 tops, 12-14MB cache, and most importantly - just 14 PCIe lanes. I'm 90% sure it's a new die, a successor to small phoenix. 4 CU of RDNA 3.5 is awful though, just a bit better than several years old 5600G/5700GHot off the press.

Sans the color scale, gives an indication of the performance.
It's not +95%, the chart is just not readableit's just like hawk point over phoenix, pointless "refresh" to fill the gap until zen 6 comes out
the slides look off, how is +95% MT possible when it's the same CPU by 99% lol

Ryzen AI 3 with 2CUs is awful. Assuming it clocks at ~3GHz, that's ~0.77 TFLOPs of FP32 performance. Even Ryzen 5 210/Ryzen 3 8440U has the same 4 CU IGP.
And all of that for the NPU. Copilot was a big mess from Microsoft.
Should run PS4/XOne generation 3D games fine at 720p.Still should be OK for 2D usage.
It's already there on the SoC. If it failed, then the chip isn't marketable to the west. If it didn't, then it keeps the product relevant for full featured Windows, which is still the biggest target market available.
Stuff with a failed NPU will likely just get sold overseas in secondary markets.
That is specifically the FP8 socket.There's some missing here, among them the AI 9 HX 375, AI Max 385, and AI Max+ 395. Aren't they Strix also?View attachment 120655

The Geekbench 6 MT score is funny. I wonder did they mix up the chips, or something else.9955HX3D preview benchmarks
I think it's a typo. Should be around 20k.The Geekbench 6 MT score is funny. I wonder did they mix up the chips, or something else.
This is correct. In fact, all of the review samples I've seen have better average clocks on CCD1 than my vanilla 7950X does.That's not possible. Even on regular dual CCD CPU's one chiplet is binned better and runs at a higher frequency.
Sounds like a "you" problem, as in, if this is an issue, you need help with it, and aren't out to attack AMD, post a thread. I have a non-X3D dual-CCD chip, and I've used a dual-CCD X3D chip rather extensively. Things for both generally work "as expected". As in, "99% of the time, the proper CCD is used, with it only not being used 100% of the time". It does require you to update your drivers, windows, and such, however. If you don't do that, or mess with BIOS settings in an unsupported way, that is a "you". If this is indeed an issue, I encourage you to open a new thread and be prepared to have an objective conversation, so that said issue can be troubleshooted/fixed (so as to rule out user error, because if it IS happening, it will warrant an RMA)Bad schedulers like in Windows?
I had to disable half of my 7950X3D to get it all working in Win 11. Unless AMD puts V cache on both chiplets next time it will be obvious no-buy from me, 12 cores with extra cache will do just fine then.
Only for things that don't benefit from more Cache.It's not only about clock speed. The V$ die isn't universally faster than the non-V$ die even at the same clock, because larger cache incurs (well, at least on Zen 4 it did) 4-cycle penalty for accessing L3. So if your workload fits within 32MB, it would be faster on the non-V$ die even if it clocked the same.

In addition to what has been mentioned, It's a server part, which comes with things like better support, etc.Question.. Why is a 16 core 4004 EPYC(4.5 ghz) + motherboard($399+$299 $698 total) close to the price of a 9950x(4.3 ghz, $542) and the 4004 runs faster ????
AMD does this with mobile parts quite often. Unsure why folks are making this a big deal, this has been happening for years.View attachment 120635
So, it's no zen6, it's just the "old" zen5 cores. Renaming and that's it.
I did all by the book - even installed Windows 11, which I regret, that stupid Xbox bar, drivers etc - games were not giving me the FPS I expected on 4090, so had to disable non-3D chiplet to get them work very nicely. Funnily enough 18 months later new BIOSes introduced new "optimised mode" for chips like 7950X3D, which in effect did the same as what I did, so clearly even past that time things were still not very good.Sounds like a "you" problem
