wccftech.com: Why The PS5’s 10.3 TFLOPs Figure Is Misleading

Show me please one post where somebody claims that the SSD is doing any graphics processing. What is being discussed is, that a faster SSD allows loading more high-quality or more varied assets, for example. If this is the new level of discourse here, then this is kind of sad.
Most of your posts are in favour of one console though lol. The article is awful btw.
I generally trust Usman, but i dont believe that we know enough about RDNA2 to deduce what clocks can and cant it hit. Only things we know is dropping the clock by 2% drops the power consumption by 10% on the PS5 and that RDNA2 brings with it a 50% performance per watt increase which is a major improvement and actually falls closely in line with the clocks.
I respect Usman on his insider reports on AMD, but the rationale for why 2Ghz would be the 'sustained' clock is flimsy to say the least. He seems to have picked that number because it showed up in the leaked github test. That was one benchmark test.
The 'sustained' clock-rate will depend on the workload, no more, no less. It may be 2, 2.1, 2.2. Maybe it can even go lower! But there isn't 'a' sustained clockrate applicable to everything. It will vary by game. It will even vary within games.
I'd suggest one side point, and speaking of misleading - teraflops alone may be a misleading indicator of real world performance. Of course there'll be a gap, but I'd be surprised if the real world performance delta lines up neatly with the teraflops delta (16% or 30% or whatever is in between) - or if it is, it won't simply be because of the compute difference. More likely to be bandwidth. If you look at benchmarks of rdna1 chips at higher resolutions and settings, you rarely get real world performance gains between the lower and higher end of the family that are in line with the tflops gaps. It's often half as large as the paper gap. Bandwidth, however, is better on XSX, but narrow/fast vs slower/wide throws another complication into the comparison with e,g, rdna1 benchmarks. We will see where it shakes out typically.
It's bad enough I wasted my time reading that but I must ask; why do they have "3.5 Ghz (SMT?)" in their fact sheet? I thought it was made clear it had SMT enabled?
It's about as compelling as forum post arguing about their favorite company countering with an even lower process node. It's not.

That's the general impression I've got in the last week or so.
People seriously bending over backwards to keep this nonsense about downclocking alive. What a shit show it has been.
Is dx12 actually exclusive. I remember people claiming things like that backn when this gen launched but it turned out to not be the case.
Laziness. But NXGamer goes into more detail, and unlike DF, also shows the GPU/CPU usage that other games are running.
I give no fucks about numbers other than the number on the end of a game that I have been looking forward to playing and the number of years I've been waiting for it. The games will speak for themselves - until then I will continue not giving any fucks about numbers. The number of biscuits left to snack on with a cup of tea is also a number I like.
People act like 10tf rdna 2 is too weak..
We have Ryzen 3.5ghz 8c/16t, 5.5gb/s SSD, GPU that is even better than Radeon VII/RX 5700XT.. Even for 499$ is an amazing machine.
Cerny should have ended presentation with some amazing next gen gameplay demo though, maybe that would make people stop comparing one another's teraflop

Are we sure MS is going to be in hardware business in three years?
I'm going to plug in an extra NVme drive to squeeze out another 10, maybe 20 TFLOPs.
They're suggesting that because MS alters their clocks with SMT enabled, maybe the PS5 does too.
We don't know - but I'm guessing the workload management stuff encompasses that on the PS5 side. I think naturally you're more likely to run into the thermal/watt limit and incur clock variation with high load SMT work (coupled to high load GPU work) than high load single threaded work. So I think they're probably letting that manage it, rather than having discrete clock steps when you have SMT enabled or disabled.
I read it in a comments section from someone with a phil spencer avatar, so it must be true.
I know that'd be like a dream come true for you, but no, I'm pretty sure they'll still be around.
I see far more acknowledgement that ps5 is weaker in power, but has various advantages. Since spec reveal.
The proof, as always, is in the pudding.
But I'm interested in seeing the cooling solution for a GPU that many believe will be operating at its peak 2.23GHz clock "almost all of the time". Even Nvidia's highest end GPUs run at way lower clocks when overclocked to their peak and with significant cooling solutions. Many doubted the GitHub leak because it suggested that the GPU would even be running at 2GHz never mind 2.23.

How is it misleading when Cerny explained it? They aren't hiding anything lmao
I really want this to end and everyone just accepts next gen is gonna be incredible regardless of what console you get. The fact devs are extremely happy with both consoles should be enough

PS5 is inferior to XSX in GPU compute at either end of the range. I don't think anyone disputes that. And so it doesn't really matter wrt XSX superiority - it is superior here in any case.
The dispute is over the arbitrariness of the clock picked in the article, or what the rationale for that was, if there was one. Especially when the article seems to ignore the key suggestion of the approach about why close-to-max clocks may be 'typical' rather than rare. Cerny may be wrong about how typical that will be, but there's little in the article to argue why. (And, in fairness, I'm not sure anyone could argue why, without access to the kind of workload data even only Cerny has for the prior generation, and nobody yet has for the next).
Not going to happen, gamers always have to be at war. The next console gen is going to be the best yet, though.
I believe that's what the estimated "potential" TFLOP power an XSX if it also used similar dynamic processing. I'm not quite sure though?
