Likely? In otherwords, they have no idea? Gotta' love rumors.
Why can't it have 64 compute units with 4 disabled for a total of 60? Has just as much credibility.
4 Compute units is 256 shaders... That is the equivalent of 1/3rd of an Xbox One GPU in terms of functional units.
However it does NOT all come down to clocks... There is no evidence that the PS5 Pro will have higher/lower clocks than the Xbox Series X, it's all a hypothesis/hype... Nor does it matter.
Efficiency plays a hand with functional units... And it depends where the bottleneck lays.
The PS5 Pro is "supposedly" running with 18Gbps DRAM, which is an increase over the Series X 14Gbps DRAM, that is only an increase of about 28.5% in bandwidth over the base PS5, bringing it up to 574GB/s verses the Series X 560GB/s. - Thus in scenarios that are bandwidth and/or fillrate starved, the difference between the two would be negligible.
That is provided Sony doesn't increase the memory bus width over the PS5.
If they bring it up to a 384-bit bus we would see 864GB/s - And then we start to see massive gains over the Series X, but that would also come with a corresponding hit to cost.
Again. That also doesn't matter.
One of the -largest- bottlenecks in the current consoles is actually CPU performance, impacted by Ray Tracing, more Ray Tracing capabilities and better CPU performance would be a massive boon in itself.
| shikamaru317 said: If PS5 Pro's GPU has about the same clock rate as PS5, it would have around 15-15.5 tflops, compared to 10 tflops on base PS5, though it could possibly be clocked even faster. Meanwhile the RAM is said to have 18,000 megatranfers a second, which would presumably mean it has a unified pool of RAM that is about the same speed as Series X's GPU only RAM. The console is also expected to have the hardware accelerated ray tracing that Mark Cerny patented last year.

And if the PS5 is using the newer RDNA3 architecture or adopts RDNA3 features like where each pipeline is essentially dual-issue, the real-world gaming performance in terms of teraflops is going to be lower on a flop for flop basis compared to RDNA2. (Again, Teraflops is bullshit.)
The reason for that is SIMDs can only issue a second instruction when RDNA3 can extract a second instruction from the current wavefront, if it can't, then then you are only going to be using 50% of your ALU's cutting your "Teraflops potential" in half.
Also, the Series X has a unified pool of ram. - It's just partitioned in a clamshell design, but it's a single pool.
| shikamaru317 said: Not exactly a huge leap in specs, but that is to be expected, Sony will likely want to keep the price within the ballpark of what people expect to pay for console. I'm guessing that Holiday 2024 we will see the new PS5 Slim no detachable disc drive model drop to $350, the one with the disc drive in the box drop to $400, and the PS5 Pro launching at $600. That would put a $200 gap between the base PS5 and the PS5 Pro, $200 getting you about 50% more GPU power, a faster CPU, faster RAM, and probably a somewhat bigger SSD. |
Considering the Series X is 20% faster than the Playstation 5... Then it will be a moderate increase over the Series X, so the jump will seem larger between the Playstation 5 and Playstation 5 Pro... But less of a significant jump between the Series X and Playstation 5 Pro.
But it also doesn't matter, games are designed for the base Playstation 5, hence why the added horsepower in the Series X is irrelevant.
I would also argue that a Pro console is irrelevant this generation, with costs increasing it's not going to come at a palatable price for many.
