There has been some enthusiasm and questions about Zen 3 APU's to replace the current ones.

Well AMD have confirmed they are coming, later this year, up to 8 Zen 3 core and 16 Threads, 35 to 65 watts, Still Vega 8 Graphics.

really am baffled with this, yes its got zen 3 cores but the rest of it is the same it seems, no new gpu architecture (hell its even got less gpu cores than previous gen, but clock speed bump to make up for it), the video stuffs been left the same also. could made a very good entry level htpc cpu but nope.
 
It is a good entry level HTPC as it, the APU is great for those uses and office stuff, its even not terrible as an entry level my first games PC, but yes like you I would prefer a stronger GPU and less CPU cores, a 4c/8t with double the GPU would be a much better balance for a starter games machine
 
Renoir is about 156mm².
Cezanne is rumoured to be about 180mm² - although why only rumoured? Major OEMs have shipped laptops with them - nobody courageous to open them up? Laptop BGA should be bare die, so could someone (not me) crack up the laptop and get out the calipers!
While I think a few 10mm² would be nice to upgrade the GPU, the more I think about it... Well, I'd rather they up'ed the cache to the full 32MB first...
 
CPU is powerful enough without the cache, not played any games on my 2,3 or 4xxx series APU that has left me thinking it needs cache, its completely held up by the iGPU, might be different under a dedicated GPU but the type of erson using an APU isn't likely to have a system to back up a proper gaming card where cache might matter but even with my 1080Ti installed in my daughters 2400g when I tried it in the past its still no slouch.

Its still DDR4, stronger graphics would just get choked by that.

any idea how choked it is with ddr4 ? as they have just jumped up the gpu core speed by what 500mhz. so curious as to how close it really is to maxing our the memory. especially with the newer cpu memory controllers being a lot stronger than the old ones.

No idea, maybe you're right and they should have RDNA2 graphics.

Okay as a small box which can game, sure unless cache was also useable for the GPU.
But for a small box with decent CPU grunt, the cache makes a big difference as Renoir demonstrated.
Idle power of those Renoir system was great though (down to around 10W even using AM4).
As for RDNA2, do we know who much larger the graphic cores are?
If they decided to dedicate, say, 80mm² to the GPU - and since 20-30mm² of that might be for video decode/output etc. and not GPU units as such - and have 50mm² of that for GPU compute units.
In that area Vega might allow 12 CUs, but if RDNA would only fit 8 CUs then it might not make sense.
 
I really hope this doesn't cost more than a Ryzen 7 5800X! :(

The external cache really helped some of the Broadwell CPUs - after all the RDNA2 GPUs do have a cache setup to help alleviate some of the bandwidth problems. Something similar for a IGP might actually be helpful.

I've had a 4650G since not long after they were released, and can tell you after months of tinkering, no matter what it needs more RAM bandwidth. I can run 2000MHz IF, 1:1 so RAM is an an effective 4000MHz, and bumping another 200Mhz+ on the GPU core adds margin of error % performance, where as adding 50-100MHZ on the RAM actually improves the performance way more.

What you need for APU's is DDR5, more bandwidth = more performance.

fair enough. maybe am5 will mean a jump in igpu performance thats worth while.

The top model is called the 5700G, (65 Watts) this could also be the cheaper 5800 people are looking for.
 
5700G only support PCIE 3.0 and GPU Freq downgraded from 2100MHz to 2000MHz. And still on OEM. :eek:

I prefer AMD make this chip 5700G base clock at 4GHz locked with GPU 12 cores at 2400MHz and PCIE 4.0 and it a win win for customers desktop retail.

Why PCIe 4? a faster NVMe?
 
Well, that quickly turned into a wishlist thread!
So let me recap:
more GPU grunt or a new GPU arch for GAC, sandys, and bulldog147
more cache for me, and I guess we can put down anyone who wants more bandwidth at least to some extend
lower prices for Cat.
PCIe 4.0
Higher clocks
Now, none of is happening for Cezzane (except hopefully Cat's prices) but for the eventual Zen4 follow up?
Who knows.
There's a rumour of a different config coming alongside these. Something like sandys suggested: 4C/8T with more GPU. AMD currently have nothing to compete at the low end but with 7nm being short I can't see them doublign the GPU for what should be low cost part.
