AMD Zen 5 rumours

[Grim5]

I think Zen 5 is going to be 4nm, according to the roadmap, with Zen 5 'C' cores presumably using 3nm.

Tsmc "4nm" is just a refined and more expensive version of their 5nm, and it's 5% to 10% better

They should have called it 5nm Pro Max or 5nm Ultra

 

[g67575]

The problem with the latency issue, is that it can only be partially mitigated by software.

Why waste time and money on a half measure, for something that could be fixed with an improved design?

I thought TSMC's 3nm (there are a few variants apparently) was meant to be quite a large improvement? In theory, couldn't AMD use the new 3nm process for a 16 core single CCX model?

Then, the cheaper 4nm for the 8 core single CCX model?

Bear in mind that Intel is on track to release 2nm Arrow Lake in late 2024... If Intel deliver 'Intel 20a' desktop CPUs on time, there's every reason to think these processors will be very competitive, if potentially more expensive then 'Intel 7' based CPUs.

 

[Troezar]

I think for general users the time to go to 16C is when it's all on one CCX. Tbh for most people a decent 8 core is still plenty.

 

[Nutty667]

If AMD was to keep/regain the gaming crown, they're going to need to release a single 16 core CCX part. I think we'll see 6, 8, 12, 16 all on single CCX chips. Possibly also 20 or 24 spread over dual CCX's.

Am I right in thinking that for 4k gaming, the CPU makes very little difference above a certain threshold?

I have a 5950x and from what I can tell the difference in FPS between that and a more modern CPU is pretty much nothing if you’re running a 3090 / 4090.

That's because you're GPU bound rather than CPU at that resolution.

Yup, that’s what I understand, thanks.

It pretty much means there is very little reason to for me to upgrade my CPU + motherboard, for the foreseeable future.

Depends, its not as easy to say, well I be gpu bound at 4k and then call it a day and just buy a better card.
I upgraded cpus the last 5 years 5 or 6 times vs once 6 months ago with the gpu.
Each upgrade of cpu brought a better gaming experience.
Even now recently in 4k.
While the difference may not be big I view this from actual usage I do not check fps numbers.

Personally I will upgrade to the zen5 x3d technology cpu whenever its out.
It be a bit better even if I dont upgrade the current card.

The 7800x3d been a pleasure to game with.

Benchmarks seem to suggests it’s only a few FPS difference, as in borderline imperceivable, although it depends on the game. So I would check out the numbers before throwing the cash down…. Particularly if you’re gaming on a 120hz monitor / TV.

AMD even internally almost always under estimate IPC gains, the chances are they could still hit a 20 to 25% performance increase with Zen 5, 15 to 20% of that coming from IPC. "10 to 15%" is minimum.

With 25% its 48,320 in R23, seems right to me that they would be shooting for near 50K with a 16 core part, tho they will have the option of a 24 core part, 8 big cores and 16 little cores tho it should be said AMD's little cores are the same as the large ones, with less cache, for example the 128 core Bergamo has 16MB L3 per core vs 32MB on the 96 core Genoa.

There could even be a a situation where you have a choice of 8+8 or 8+16 as well as 8 / 8+8 with 3D Cache.

Also, these will be competing with 14'th gen, not Arrow Lake, that's Zen 6.

ipc is a mess to measure with as it depends on cpu design and application that benefit from it more or less.
always good to downplay as reviews be more, oh we got more power
Cant wait to buy zen5 x3d tech tho

Yup, also 4K here. 5800x3d swapped in for my 5900X and I'm probably done, outside GPU upgrades for a while.

Maybe 7x00x3d once it's a common second hand part and work it forward like that with big GPU, decent CPU till 4K's a bit more standard and I start to see CPU strain.

Interesting to see if we get a similar uplift for the 8800X3D

So pretty much as normal which is a good thing

 

[Vimes]

So these Zen 5 8950x, et al, will fit on the x670 board...? But could it be a possibility at their time of launch that another chipset, perhaps with enhanced features, could also be offered..?

Would be highly unlikely that they don't

But could it be a possibility at their time of launch that another chipset, perhaps with enhanced features, could also be offered..?

Based on previous releases, then yes, quite likely that there will be a new refreshed chipset and boards at the same time.

Not bad, its better than 1.6% Its also an engineering sample, it seems that AMD are getting consistently 15% or more every new chip since Zen 2.

They will drop in existing AM5 boards but vendors will also release new boards for if you want the new stuffs...
