It will be a 4 core 8 thread chip, consoles cannot handle a full blown Ryzen CPU with 8 cores... The TDP is still too high, the only upcoming AMD mobile chips are Raven ridge based which max out at 4 cores and 8 threads, but don't let number fool you those 4 cores and 8 threads are night and day to what the current generation has.
The CPU limitations would not exist so there would be no need for "pro" version that would play 1080/60 since both won't have a issue regardless of core count with Zen CPU's... The real issue is GPU and price, in order to get a GPU better than the X1X you will be looking at PS3 launch all over again in terms of price, focus on price you will end up with a X1X level of GPU but with a CPU that can handle that power.
The un-informed people who are expecting miracles with the coming generation, need to lower their hype because the industry is a open book right now and AMD has little to nothing up their sleeve let alone their road map for the next half decade that will be enough for 4K/60 with console TDP levels.
Also I would like to ad that dynamic resolution will still be a thing regardless of the CPU jump 4K is still a nightmare to run on mid range hardware and if the PS5 gets RX 670 performance you are still looking at 1070 level of performance which is great for 4K/30 with current games but future games we don't know and with poorly optimised games like Final Fantasy and Monster Hunter still around its safe to say that 4K is not guaranteed with the coming generation with every game.
I'd like to be a bit optimistic about the CPU side specially if it's a 2021 actual release. At least 8 Cores / 8 Threads. At least as real as the 8 cores of current gen systems since I'm not sure how gimped the caches are oh similar elements.
We already have a Ryzen mobile SoC that's 12 watts with 4 cores / 8 threads at 2.2 Ghz and that seems to even has a 640 shader GPU.
If the PS4's past could be anything to go by, an unusually high CPU core amount (and low clockspeeds due to being designed more for tablets) seem realistic.
I think you're right that we should expect dynamic res too specially more frequent in the one who's gonna have the weaker console next gen. Even current gen has issues with 30 fps.
To add a little more sadness (depends on how you wanna look at it). RAM/VRAM seem also expensive and I only expect 16 GB total ram for the weakest console. Some of it probably more of a regular VRAM to save cost and only house the OS.
You can be optimistic as you like but that doesn't change the fact that 8 core mobile ryzen chips dont actually exist nor are they in the pipeline, they max out at 4 cores and 8 threads... The only way to get 8 cores would be to use infinity fabric to essentualy glue 2 chips on to one die which is exactly what the current generation on consoles CPU's are, two 4 core Jaguar chips on one die.
Also 8 cores and 8 threads?... Its just 8 cores, threads are double the amount of cores you have and if its not a SMT chip then its just a 8 core chip. Maybe you are talking about 8 cores and 16 threads?... If so not possible in terms of TDP.
As for your RAM expectations?... GDDR6 is expensive and expecting anything more than 16GB is just delusional.
The next generation will more or less look like:
- AMD Zen Picasso 4 cores 8 threads at 2.5 - 2.8 GHz or two 4 core chips on one die with SMT disabled making 8 real cores at similar frequencies
- GDDR6 10-16GB
- 1TB SSHD
- Custom Polaris 30 based GPGPU (underclocked RX 670/680s)... Or MAYBE Navi 10
- 4K Bluray
Navi 10 is rumoured to be Vega level of performance but with lower TDP due to being 7nm, but a console varient would lower the clocks to hit even lower TDP than a desktop so the performance may even match that of a Polaris 30 desktop chip which will more or less be slower than Vega but faster than Polaris 20 making it redundant for console use and rumours always over estimate during console launches, so the safe bet is a Polaris 30 based PS5.
I don't know... But I do know that their are no native 8 core mobile chips from AMD in the works.
FYI, "Polaris 30" is 12 nm Global Foundry fab'ed GPU which is just Polaris 20 (232 mm2 size at 14 nm) evolution.
A 7 nm could support ~464 mm2 size GPU at 14 nm as ~232 mm2 at 7nm, hence PS5 will NOT be "Polaris 30".
For reference, 14 nm Vega 64 has 486 mm2 size GPU with useless high bandwidth cache.
I prefer for AMD build upon Vega M GH with 24 CU and 64 ROPS and scale this GPU design into 48 CU with 128 ROPS (read/write units are very important to extract performance from compute units). Workloads like crypto-currency uses TMUs at 1.536 Ghz as it's read/write units which enables Vega 64 to rival GTX 1080 Ti (224 TMU units at 1.6 to 1.8 Ghz).
PS4 Pro already has Vega CU RPM (rapid pack math) features hence it wouldn't be any Polaris CU design for PS5.
RX Vega and Xbox One X GPU designs also delivered multi-MB L2 cache for ROPS improvements. This is similar to NVIDIA Maxwell/Pascal ROPS improvements, but AMD didn't reach GP102's 88 ROPS (GTX 1080 Ti) or 96 ROP (Titan XP) design. Vega 64 remained in GP104's 64 ROPS level.
28 nm to 16 nm, PS4 evolved into PS4 Pro with GPU gaining 2.3X compute power, but Sony didn't evolve memory bandwidth by 2.3X (main complaint from devs).
(Speculation, based on history)
1st, 16 nm to 7 nm, PS4 Pro (year 2016 APU design) evolved into PS5 with GPU gaining 2.3X compute power, hence estimated GPU TFLOPS would land around 9.73 TFLOPS FP32. ROPS could evolve into 64 ROPS or 128 ROPS.
2nd, 16 nm to 7 nm, Xbox One X (year 2017 APU design) evolved into PS5 with GPU gaining 2.3X compute power, hence estimated GPU TFLOPS would land around 12 TFLOPS FP32. ROPS could evolve into 64 ROPS or 128 ROPS.
