As far as i know PS5 doesn't use repurposed defective chips and slow PCIe 2.0 bus which seems to be the bottleneck here, so no i don't consider it to be 'the PS5 CPU/chip'.that CPU is in ps5 ? its slow
Cecret Cerny Ceause is the reason. Wish people would realize by now. I get the console warriors get clicks here, but it's time that the right info is used, rather than armchair devs.Why is anyone expecting PS5 CPU to be faster than desktop CPUs. Its an APU and only one component among many for a device that retails for 400$. The CPU is more than enough for what it is paired with especially for devs who have been working with jaguar cores and still producing good-looking games. Even the low CPU of current-gen consoles are god-tier compared to older gen including Pro/One X. It is not a bottleneck on gpu. You can run 4K60 games on modern i3 11th gen if you are not planning very high and ultra setting. The PS5 aims for 4K30 1800p-2160p/ 4K60 1200-1400p with most setting on medium if not low.Testing it with ultra setting is not ideal. What matters is image quality at the end of the day and framerate. The hardware is balanced on that. And it is a damn good machine. Also what's up with 8$ and 16$?
Seems quite slow.
that CPU is in ps5 ? its slow
Only 25% worse than the Ryzen 3800x. Not bad at all.Test shown in OP is completely limited by PCIE 2.0 x4 bus. In CPU centric tests it looks like this:
At PCIe Gen4 speeds, no it doesn't. Please let's stop this. We have data from NVIDIA showing how core-heavy task it is and can use up to 24 cores on a 3rd gen Threadripper.and here the you will realize that a modern desktop PC cpu could run a PS5 (or Xbox for what it matters) game and at the same time do whatever decompressor are doing and still have probably power to spare
Looking at that graph 24 cores are needed for 14GB/s. No game will need that bandwidth, not until 2040 at least.At PCIe Gen4 speeds, no it doesn't. Please let's stop this. We have data from NVIDIA showing how core-heavy task it is and can use up to 24 cores on a 3rd gen Threadripper.
And You won't find more than 6-8 cores in most modern gaming PCs, let alone 24.
This is why RTX IO GPU-based decompression and DirectStorage are being introduced.
Hey i thought ps5 cpu is ryzen 7 3700x, did I miss the News somehow?
14GB/s is the decompressed bandwidth.Looking at that graph 24 cores are needed for 14GB/s. No game will need that bandwidth, not until 2040 at least.
Then why link the worst picture in the OP, some people smh. Thank you for different graphs.Test shown in OP is completely limited by PCIE 2.0 x4 bus. In CPU centric tests it looks like this:
The one in the consoles aren't mobile versions of the Zen 2 desktop CPUs, the Jaguar CPUs are what you would call mobile CPUs cause they were designed for low-power use with notebooks & tablets. The console ones have slight adjustments (like the FPU register cuts on PS5's CPU) and are clocked slightly lower than their PC counterparts, but they're still desktop-class CPUs. And plus, audio processing & data decompression from storage are completely offloaded from the PS5's CPU cores, so imagine how much more CPU horsepower's gonna be available this time around for current-gen only titles in a few years (and these CPUs support hyper-threading on top of that). It's gonna be insane, the CPU jump from last-gen is MORE THAN enough.It never was. More like mobile, lower clocked Zen 2 than desktop part.

Yes, the consoles only run games and are not general-purpose like PCs, thus the massive L3 cache cut on both console CPUs, still doesn't make them "mobile" CPUs. Again, the PS4/Xbox One CPU is a mobile CPU because of it's architectural design which is best suited for tablets & other low-power devices. The Jaguar CPUs consume less than 20W of power, that's the definition of a mobile CPU.Zen 2 desktop, 32MB cache:
Zen 2 Mobile, 8MB:
PS5/XSX CPU has 8MB...

Dude, those games are running on a R9 5900X CPU (12C/24T) prototype (not the 2020 version) with 192MB of stacked L3$ being compared to the 2020 5900X with 64MB of L3$ and the performance uplift is decent. They're going overkill with it cause they can, the consoles are gonna be just fine with 8MB of L3$ across the board, but they aren't "mobile" versions. You gotta search up the definition of a mobile CPU.Fuck me, AMD APUs are based on mobile versions of their chips. And cache is THE MOST IMPORTANT for gaming. Why AMD will make Z3 refresh with more cache targeted for gamers?

Single-core wise it's Zen+ level, and multi-core wise it performs similar to a desktop Zen 2 Ryzen 5 3600 (a tiny bit better) in rendering workloads.It's basically a Zen1 CPU. It's still a huge jump from Jaguar cores on the previous gen.
But they should have kept that 32MB of L3 cache. With that 145ns of memory latency, the CPU will spend too much time waiting for data to process.
If only AMD already had 3D cache in time...
The weird part of this 4700S is that the CPU can only access a part of all that memory bandwidth.
And without a full GPU, the rest is just wasted.
I think console engineers are smarter than most of us and can make sensible decisions. Die space isn't free, with that much increase (x4) in cache size they would have to make significant cuts to GPU part, which certainly isn't ideal for a mere ~ 10% increase in CPU IPC.It's basically a Zen1 CPU.

It's a monolithic design rather than chiplet so 32MB wasn't feasible and had to go. Even the latest Zen 3 desktop APUs have only 16MB of L3$.
Comparing is fine, people need to compare things all the time. Especially when the consoles and PC mostly run the game games.Ps5 is a great piece of hardware for the price. Unbeatable, as matter a fact, both next gen consoles are sold at a steal. But it shouldn't be compared to mid range, high end, or enthusiast PC's
You are the first or second biggest console warrior on this channel.Cecret Cerny Ceause is the reason. Wish people would realize by now. I get the console warriors get clicks here, but it's time that the right info is used, rather than armchair devs.

Thank Jim Keller for Zen architecture and a bunch of other engineers and members of the team behind Zen+, 2, 3, 4 for all the improvements and advancements.Thank Gabe I got a 5800x as a current gen CPU \o/
Same 8 core 16 thread Zen 2 architecture as the 3700x, yes, but with only 1/4th of the L3 cache. 32 MB vs 8 MB.Hey i thought ps5 cpu is ryzen 7 3700x, did I miss the News somehow?
Why do people actually believe that though? People are claiming 3700x/3800x well after it was confirmed to be far from the case. Then people get mad when I point this out. WTFSame 8 core 16 thread Zen 2 architecture as the 3700x, yes, but with only 1/4th of the L3 cache. 32 MB vs 8 MB.
The PS5 APU is only 300mm2 and includes the GPU as well as a pretty complex I/O block. A slightly bigger chip wouldve offered more performance for sure, but wouldve also increased the thermals and cost. For $500, you are getting a $400 CPU (albeit paired back slightly) and a $379 GPU and a $180 SSD.
Sure. But Lord Gabe is blessing all these people.Thank Jim Keller for Zen architecture and a bunch of other engineers and members of the team behind Zen+, 2, 3, 4 for all the improvements and advancements.
It is (just like in the xbox) a lower clocked 8 core Zen 2 CPU with reduced cache. And also Sony removed some things on the CPU side. But CPU results are also much lower because of GDDR6 memory with higher latencies than DDR4. Especially Ryzen likes low latencies.Hey i thought ps5 cpu is ryzen 7 3700x, did I miss the News somehow?
Yes, more cache would have worked well especially as GDDR6 is used and those latencies are not great for a CPU. Cache is really simple (and has a low defect rate) but would have taken a huge part of the Die and that space is better used for the GPU as it is more important for the overall speed of the console.Fuck me, AMD APUs are based on mobile versions of their chips. And cache is THE MOST IMPORTANT for gaming. Why AMD will make Z3 refresh with more cache targeted for gamers?
So a Ferrari body with a Fiat engine.It is fully functional CPU from PS5 with higher clock even. But handicapped by shit PCIE slot and memory type not optimal for PC cpus.
You would be surprised.Taking a wheel from a Ferrari doesn't make your car a Ferrari.

Yeah, MS claims it's about 3x (minimum) improvement over One X Jaguar CPU, and up to 4x depending on the title.The uplift moving from last gen consoles to current gen is pretty impressive if you ask me. Just looking at how backwards compatibility is performing - we're seeing greater than double framerates and usually at much improved resolution and detail levels, plus massively improved i/o performance in boxes that cost only a little more than their predecessors.
If you consider these gains to be more-or-less baseline due to them only leveraging a minimal amount of the new hardware's feature-set and capabilities, seems to me that the future looks pretty bright.
