Sony PlayStation 5 Pro Details Emerge: Faster CPU, More System Bandwidth, and Better Audio

[AleksandarK]

Sony is preparing to launch its next-generation PlayStation 5 Pro console in the Fall of 2024, right around the holidays. We previously covered a few graphics details about the console. However, today, we get more details about the CPU and the overall system, thanks to the exclusive information from Insider Gaming. Starting off, the sources indicate that PS5 Pro system memory will get a 28% bump in bandwidth, where the standard PS5 console had 448 GB/s, and the upgraded PS5 Pro will get 576 GB/s. Apparently, the memory system is more efficient, likely coming from an upgrade in memory from the GDDR6 SDRAM of the regular PS5. The next upgrade is the CPU, which has special modes for the main processor. The CPU uArch is likely the same, with clocks pushed to 3.85 GHz, resulting in a 10% frequency increase.

However, this is only achieved in the "High CPU Frequency Mode," which steals the SoC's power from the GPU and downclocks it slightly to allocate more power to the CPU in highly CPU-intense settings. The GPU we discussed here is an RDNA 3 IP with up to 45% faster graphics rendering. The ray tracing performance can be up to four times higher than the regular PS5, while the entire GPU delivers 33.5 TeraFLOPS of FP32 single-precision computing. This comes from 30 WGP running BVH8 shaders vs the 18 WGPs running BVH4 shaders on the regular PS5. There are PSSR upscalers present, and the GPU can output 8K resolution, which will come with future software updates. Last but not least, the AI front also has a custom AI accelerator capable of 300 8-bit INT8 TOPS and 67 16-bit FP16 TeraFLOPS. Audio codecs are getting some love, as well, with ACV running up to 35% faster.

"Audio codecs are getting some love, as well, with ACV running up to 35% faster"

What does faster audio codecs mean exactly?

• More convolution reverbs can be processed
• More FFT or IFFT can be processed

That, basically.

I wonder will Microsoft also release mid gen refresh?

Phil Spencer said they had no plans to months ago, so he was either full of crap, or they're fully screwed when GTA VI drops.

The RT performance increase means that probably at AMD realized that RT is important if they want to keep selling GPUs with a meaningful price tag and profit margin.
Better late than never I guess...

This information about RDNA4 is interesting, but all this improvement(Up to 4x) is only in RT. Good for anyone who cares.

However, what piques my interest is the rasterization capabilities of this new architecture, This information the PS5 Pro doesn't bring to light, because most of its GPU is still RDNA3, apparently. We can expect to acquire a few bits of concrete data only when the launch of the RDNA4 GPUs draws near.

The scaling makes no sense, they claim 45% in raster i.e meaning the thing has 50% more shaders (a 7700XT basically), however this makes no sense, you can't get 4X RT with just 50% more shaders. RT performance scales with shader count, this applies even to Nvidia architectures.

So they're either conflating this with something else or this is a completely made up number. 4X RT would make it faster than any AMD GPU with a little more than half the shaders lol.

According to videocardz, the new GPU isn't a regular RDNA3, but a custom model using RDNA4 technology on some aspect....

Currently, the number of RT cores is directly tied to the number of Compute Units (CUs), with each Workgroup Processor (WGP) housing two RT cores. However, if RDNA4 were to double the count of RT cores/CU, it would represent a remarkable advancement in efficiency and performance for RT;

I think he knows there is a large player base that really doesn't care about 30 fps gaming, and those tend to be Xbox console owners, so I doubt he is worried, it will still sell like hotcakes for Xbox series x owners.

 

[Double-Click]

Hard to say I guess, I always take "performance mode" (when available) on console, but I've also gamed along side PC since forever too.
I don't see the XBX handling anything above 30FPS for GTA VI and that's even with upscaling, and turning settings down.

If the RT cores were doubled and this was some advanced RDNA4 design that would still suggest only 300% increase in performance not 400%, the number is inflated no matter what.

I am actually really annoyed that they just didnt target Holiday season 2023 for the Pro. I just bought my son and wife the Slim version.

Could the advantage lie in the ASIC dedicated to upscaling compared to the PS5's employment of RT + FSR?

PS; I just hope they don't reveal that all the performance is derived from a fake frame generator. XD

Every game now sounds like an autotune rap song

 

[Space Lynx]

ps2 audio sounds fine to me, not sure what the audio crap is about either to be honest.

More audio effects simultaneously basically.

Tbh, I doubt most people will care because either the games simply don't have that much use of audio processing power or when they do you won't notice for reasons (5 dollar audio setup, lack of good ears or whatever)

 

[TechLurker]

I guess Audio enhancements means more virtual surround sound processing. Which would make sense given Sony's heavy pushing of medium to high-end headphones and headsets in both gaming and audio fields. Maybe could even work with their virtual surround sound speaker system that delays sound so it sounds like something is really behind you even if there are no speakers there.

Beyond that, my guess for RT is maybe dedicated chips and optimized RT coding via select test games? Even if RT elements were doubled, there's still a shortfall that's either made up with a custom RT solution, or heavily optimized RT coding.

At any rate, I suspect Xbox might be waiting on the PS5P to show up first before doing their own version. They have no reason to rush; they've effectively lost the console war this generation, and even if they put out a new system, it's not like it'll allow them to beat Playstation's sales. If anything, their focus on Xbox Gamepass and joint releases on Xbox and PC means shifting more towards making money off subscriptions rather than consoles.

 

[Nunca Morto]

The enhancements overall are good i think, but in my opinion they need to put a little less power in the GPU than we see in this rumor and put more effort in the CPU, like put a zen3 or zen4 to achieve higher fps in newer games.

I don't think there's much need. It's a Zen2 8-core CPU, it's performant enough for all games currently available and for pretty much all games that may launch in the console's lifetime. The GPU likely tends to be utilized and strained a lot more.

Indeed, consoles have exceptional optimization on the CPU front. It's quite astonishing to think that anything could run smoothly on the previous generation's Jaguar-based Consoles. Nothing would run properly on a PC with a similar CPU, no matter the GPU used. lol

 

[phints]

No. Compare a game like Battlefield to COD. Battlefield had reverb, directional audio, ray tracing on the audio for destructible environments, etc. In COD you can barely even hear footsteps let alone where they are coming from or to account for a dynamic environment.

Audio makes a huge impact in game and a faster chip will be great.

 

[THU31]

Nice console, but what games am I meant to play on it? No announced first-party titles other than Marvel. By the time Horizon 3 or a new Naughty Dog game comes out, I might as well wait for the PS6.

hmm, i see.
