Digital Foundry: In Theory: Is PS5 Powered By AMD's Gonzalo Processor?
- Thread starter jsnepo
- Start date
The numbers are the important part.
Everybody already expected it to be Zen2/Navi based but without numbers we can't say much about its performance.
Well, sure, I thought that was a given. Haven't watched the video yet, but I thought they were speculation based on the gonzalo processor specs.
Well, if we do not know specific numbers, one could say that we do not know the specifications = specs.
I dunno, the video made a solid case for why there was convincing evidence that the benchmarks represent testing the chip.
It cross referenced specs indicated by the model number and produced a range of TF values the PS5 would run at depending on how many compute units they put in the package.
(My pet theory: Sony's putting their board budget into the 39x faster SSD loading and figures it'll make for more transformative, better games than winning the TF war against Microsoft—so they'll probably have compute units on the lower end of that spread.)

1.6 ghz base /3.2 ghz max speed cpu
1.0ghz base / up to 1.8 ghz boost gpu ( may be lower than 1.8)
Richard says to take the info with a grain of salt but the Gonzalo product code interestingly match to previous console apu product code. All the leaked information is based off the Gonzalo product code. 3.2 ghz cpu speed has been rumored for awhile so this doesn't sound too crazy.

leaks show Navi might have less CU's, so like 20/30 CU's at 1.8ghz on 7nm is possible, Nvidia's huge 2080 Ti already gets past 2ghz on 12nm. cooling issues might make them downclock to like 1.6ghz though, PS3 was also downclocked at the last minute & the Xbox 360 also should have been.
Navi supposedly focuses on gaming perf and pixel pushing rather than compute. There was a supposed leak of a Navi card that is meant to replace the 580X and it only has 20CU but a lot better gaming performance overall so the CU calculation determining TF might be off this time.
It's impressive for console size box with limited TDP budget. 4ghz is for pc, consoles can't do that realistically Lower your expectations when it comes to consoles.
You're not going to get 1=1 speeds though, so for a console it's still decent.
Even if the CPU was only 3.2Ghz, it still absolutely annihilates the Jaguar, which is the most important thing.
I mean yeah but these are consoles with specific thermal limits. Your not getting 4ghz in a console. It's not stable enough from a thermal level plus the wattage needed as well.
Sure, I've got one doing that right now.
The thing is, it's a 105W CPU in an ATX tower and has a desktop cooler and fan.
Console thermals are always going to result in some compromises to fit the small case's thermal envelope. Doubly so with GPU cores on the same die
Speculation is the best part of next gen. Once everything is revealed the anticipation is gone.

CU isn't a good way to determine TF in Navi cards based on the leak.
I would wait for official numbers from Sony before making a sad face. :)
lol
I did think of Speedy Gonzales myself when I read the title.
People saying that it may be below a certian number of TeraFlops the chipset would be a custom one, which would be sprinkled with "special sauce" I am worried that the speculation will be out of control for the next twelve months (whatever it is) before the true spec is announced by Sony.

I would assume power consumption and heat load will be a huge factor in the specs of PS5, plus they need room to grow with PS5 Pro. It all really depends on the price, but 3.2ghz and 10-12tflops would be a dramatic upgrade for next gen baseline and if they can magically fit that in a $400 box... crazy times ahead
Vega architecture has 64 shaders per CU for 4096 stream processors with its 64 total CU but Vega is imbalanced as it lacks geometric pixel pushing power compared to its compute performance which apparently Navi turns on its head with more focus on gaming performance so we could easily be looking at more than 64 shaders per CU for Navi considering it keeps up with Vega 64 CU GPU in graphics and bandwidth perf even though the leaked card only had 20 CU. Determining TF based on 64 shaders is probably wrong in the case of Navi.
Then starts the awesome discovery how developers use all new features and hoping that those features will become to pc as well. (Ie. Pixelshader accessing barycentric coordinates.)
Beat me to it.
But according to MS it will be this fast compared to Anaconda.
