No, the PS5 won’t offer anywhere near the graphics performance of Xbox Series X: Navi benchmarks prove it

Sony's claim that high clockspeeds offset its meagre shader allocation on the Playstation 5 doesn't hold water when Navi overclocking results are factored in.

While I think both will be great, I think it's just logical to conclude the Series X will have a fair deal more graphics performance than the PS5. The Series X will perform at a locked 12.155TF and the PS5 can boost up to 10.28TF, even if it sustains that clock that's still a fairly significant performance delta, and in the scenario that a non-boosting PS5 GPU drops down to around 2.0GHz per CU, which is likely, it actually works out to around 9.2TF. I don't think teraflops are the be all end all by any means, but these GPUs are both RDNA 2.0 and share far more in common than sets them apart so their TF numbers do hold a fair deal of relevance comparatively.

This author doesnt realize that yes it's less powerful compared to xsx but this is where the ssd comes in where the ssd is that quick it becomes like a pool of Ram which can offset alot of things like Field of view. pop ins etc without allocating alot of it to the GDDR ram it's also that fast that it can probably able to download and stream 8k textures to a 4k display without hitting the performance that hard.

1) It's harder to keep 52CUs fed than 36CUs.
Depending on the level of parallelism.

2) There has to be some throttling mechanism for XSX GPU.
Otherwise you could "burn" it by using something like Furmark and it would overheat and the console would stall.

3) frequency scales very well on GPUs as Sony's main architect explained. TMUs and ROP and cache are oc as well. Your comparison for RDNA1 scaling is not valid for PS5 and RDNA2.

That being said, XSX has an advantage over PS5 in terms of GPU but i expect it's in the realm of 10-15% not 30% We'll see anyway.

Lol, it might be a fast SSD but it's still roughly 2 orders of magnitude slower than the GDDR6 ram that those textures still have to go through anyway. Plus the amount of memory really isn't its biggest weakness.

Ever since the days of Xbox and PS2.
Sony's console wasn't known to be as powerful as MS's.
It was never about power but what games each system would offer.
And since this is a new era, both companies will have a fresh start on how they would cater to their playerbase.
I just hope MS would put a fight this time. Maybe that way they would return their main office back to Japan.
Ever since they moved it to California, they've been doing some weird and questionable decisions(like censorship and those wtf presentation).



BOOZE

Sony never said it would use the SSD as a Ram pool. Now Microsoft on the other hand did. The PS5 is going to be good, but Microsoft's Xbox series X will have better looking games. All Sony talked about was load times.

Real life performance is everything and and RDNA 2 is not even out yet you dont even know what your talking about and the ps4 pro and xbox one x its not that much different in graphics anyway and you dont seem to follow up whats happening the new consoles are not about graphics anyways they say that it will only look more life like but the graphics will be pretty much the same as the ps4 pro or xbox one x

What this author seems to be forgetting is MS vs Sony's stance on their respective unveils. MS revealed the Xbox SERIES X. The name itself implies that we are looking at a stable of devices. The 12 TFLOPs of performance is their upper limit, at least for the next 3 years till they come out with an overclocked chip of their own Pro model (if at all).
Whereas the PS5 is clearly ONE console, it's the base model. Meaning every ps5 owner would at least have an ssd that is that fast, a GPU CAPPED at 2.23 GHz - Cerny clearly said that their thermal management approach allows them to go higher (an approach employed way back in the day with the psp where the handheld was unthrottled to its max cpu/gpu frequencies later down its lifecycle) - and a Zen 2 8C/16T CPU again CAPPED at 3.5 GHz.
We've known for a while from supply chain rumours that Sony was doubling down on its cooling solution for the ps5. Now with such skyhigh clock speeds it makes more sense.
Also Sony did not claim that more TFLOPs doesn't make a more powerful GPU, they rightly said that a higher clocked GPU with the same TFLOPs would give better real world performance.
And you seem to very boldly/callously be overlooking the extent of custom silicon inside the ps5 designed to remove bottlenecks in the entire gaming hardware stack. A RDNA 1 gpu OC'd could never begin to offer up the same gains as a console GPU at higher default CAPPED clocks simply because the first is a single part whilst the other is highly integrated on a single design ethos.

Most of the commenters are wrong. I agree with NotebookCheck, their assessment is correct.

Sony has already has purchased and locked in the specs. They're on damage control. The secondary improvements from frequency are real, but they have a limit of diminishing returns. Especially when factoring that overclocking, something you don't want in a small form-factor, or for consistency, or long-term, or redistricted power supply.

In general, you want a good balance between the frequency/single-core performance, and of wide/more-cores. This applies for both CPU and GPU. However, for CPUs this balance is closer favouring frequency/single-core performance. Whereas for GPU you want wider/more-cores.

Microsoft's unit is better in the Software/SDK, in Backwards Compatibly, in Cooling, in the SSD, in the CPU, and in the GPU. All up it will use slightly less power, run cooler, run quieter, and give an extra +30% performance... AT THE SAME PRICE.

Yet, the PS5 is going to win next-gen because they will end up having the better exclusive games.
