Does the size of the CUs vary as well? I mean can they make smaller CUs inside SE to put more of then for more parallel processing? Or is the size of CUs fixed for the architecture?

Fixed as far as I know (transistor count). Though these are semi-custom chips, but that generally doesn't drift too far from the standard. I would assume XSX is using the standard RDNA2 WGPs.

Well, if according to Cerny that it is easier to utilize less CUs, then why AMD doesn't decrease the number of CUs while increasing their size? I mean to keep same silicon size but with less number larger size CUs. Does my idea make any sense?

Not really. :messenger_tears_of_joy: JK

CUs grow as functionality is added. You could put the functionality of 2 CU in a larger unit and call it one, but utilizing them wouldn't be any easier.

Even games from 15yrs ago have no issue utilizing GPUs considerably wider than what existed when they were released, wide GPUs are not a problem. Nvidia and AMD are about to release some real monsters that will make the XSX chip look narrow.

Clocks are harder to reach let's call it as it is when he had a huge CU advantage it was no issue. Now he has less so more CUs are impossible to program for. When the PS5 pro comes out with more than 52 CUs not 1 person who is crying 52 CUs need a god to program will say a peep. Sony just has great messaging and astroturfing. They made high TF and high CU a bad thing it was brilliantly played by them.

I’m still not convinced on only a 1gig reserve. The dvr video being the prime memory hog.

But I can hope for some added DDR4 stashed away somewhere just for that purpose. Or even some cheap flash soldered onto the USB bus like late xbox360 models.
The PS5's SSD is so fast that the console's 16 GB of memory can be filled in just two seconds (2 GB in 0.25 seconds). So I think only needing 1GB while gaming is possible. Moment you press the home button. PS5 can dump 3GB and use it for OS features. Remember PS5’s SSD can surpass DDR3 RAM. So yeepp.

How does that avoid constantly writing a video file to the SSD?

Welp, What will that be? I dont think its the PS5 or anything related.


After this, Nishikawa reportedly confirmed the scoop is Sega-related after accidentally letting the name slip when mentioning the company’s public relations. However, it did not seem problematic. After his slip-up was pointed out in the comments, Nishikawa said, “Did I say Sega? Then it’s Sega.” He also said it’s not Dreamcast 2.

Why would anyone want a Dreamcast 2 over a Sega Mega Drive 2 or Sega Master System 2?

I think we'll see the actual console when they reveal the price, and I don't expect that to happen until August or September. But I mean they could also just stealth-drop it out of nowhere on a random Tuesday next month like they did with the controller.

As depressing at that sounds, i think you may be right.

Sony will wait until the last possible moment to reveal both price and console.

Cerny said that (about less CUs) in the context of the high clock speed the PS5 is running. Without the higher clock, more CUs would be better.

The higher clock is achievable due to the SmartShift and variable clocks/load system they’ve implemented. That part is currently unique to the PS5 console. But if Sony are successful with this design, it will no doubt become a mainstay of future consoles.

Sure.

I seriously doubt a twitter nobody will have seen or be given access to the final console
The shape was used before from the sony presentation. Has nothing to do with access. Plus it was mostly a joke.

It lists Bioshock?????? New bio shock incoming?!?
However, this is nothing new. :messenger_beaming: 2k officially announced a new BIOSHOCK last year. However², it will take some time before we see anything of it.

Wow. I am confused where the increased performance comes in then. Just four more channels and maybe a few more levels of priority can mean such a performance differential? I'm probably being dense because it's late but....I'm not understanding this. I THOUGHT I had a handle on it all...till this post. :)
Was just watching that Moore's law is dead video, and he basically says that the priority levels alone are a huge jump in speed.

With 2 priority levels, Every change on screen has a command, it needs to make sure that X happens before Y due to either this restraint or some other variable. If you have millions of commands that are only either/or, nothing else can get through, it gets backed up, even though these happen every frame, and the rate in which they're processed is still quick, it can be much faster.

With 6 priority levels, every single frame gains speed, because the commands can flow in so much faster without having to compete with an instruction before it.

That's how I've understood it, if I'm completely wrong please correct me.

I think your understanding is accurate.

The only problem is that multiplat games can’t assume there are 6 priority levels for SSD access. Devs will either ignore those priority levels or include code to make use of them only on the platforms that support them.

Now Cerny did say they would map 6 priorities on to the 2 (that’s how manyhe said off the shelf SSDs have - some people claim they could have 4 priorities) available in 3rd party SSDs for expansion.

Assuming Sony get an algorithm working to do that and it isn’t majorly processor intensive, they might give the source or the algorithm to 3rd parties so they can work with 6 priorities across all platforms regardless of the underlying logical priorities available.

Cerny said given the choice of two ways of reaching X teraflops, he prefers running the GPU faster rather than adding more CUs.
He’s comparing PS5’s 10 teraflop GPU to a hypothetical configuration where the same 10 teraflops is reached at a lower clock speed.
He gave his reasoning why.

At no point was he saying higher clock speed/lower CU 10 teraflops beats lower clock speed/higher CU 12 teraflops.

That’s wishful day dreaming by people that half listened. Not at all what Sony said.

they are trying so hard. its pathetic.

moore's law commented about the demo in his latest video.
"Quite large". ROFL. The relative difference is even less than Pro to X.

The best part:
"Epic runs a demo on a PS5 devkit. Sony paid them!!"

"Youtubers get invitations and free Xbox gear from Microsoft to show off the new console, with nothing but praise. Sounds trustworthy to me. No paid marketing at all."

It's bizarro world.

I never got the idea why it's important "my" console is the best/fastest/strongest one in the world.

The stupidest thing is that everyone has to realize that the PS5 and Series X are only marginally apart, an area where the difference in performance is almost irrelevant. Why there still is a dispute over 4 FPS difference is beyond my imagination. Some probably want to compensate a small dong.
