So there is still a possibilty that ps5 cpu L3 cache is unified..


Probably just the onboard SRAM that will most likely be used as L3 across the chip for CPU & GPU.

So Hotchips brought a lot of Xbox fans dreams back to earth. No 32MB L3 Zen3, No 80Rops, no customized RT hardware that stomps RTX offerings.

It was fun to speculate lots of things in the past year, but honestly we ended up with two fantastically designed consoles.

Did you watch the video? I know it's one of the features of Zen 3 but he says there is a possiblity.

80CUs? are you drunk, we knew about XSX CU count in march. L3 cache was reduced as expected, PS5 has same amount as XSX and Renoir mobile APUs, I can assure you

What does this mean in practical terms compared to the PC parts? Do they go some part to justify the much higher PC cost? 😊

Mad thing is ZEN 2 and RDNA 2 aren't even properly out yet... And here we are, talking about the possible improvements to Zen 3s and RDNA 3s AND even 4s!
Zen 2 released july 7 2019, it's more than 1 year old, we are waiting for Zen3 which will release in 2 months from now

I don't recall Xbox fans stating any of that you mentioned. And so what if they speculated? All i see is Hot Chips stating that XSX's audio chip, design is just as capable as the PS5s, which sony/fans have been touting heavily. I guess you can basically take the PS5 superior audio narrative out of the equation now.

Have you seen Xbox rumors at the end of 2019, fans were trying to one-up anything revealed about PS5. Seems silly now, but then....oh boy
Yeah, cause sony fans haven't been doing the same thing? What about that 13tf non sense that many sony fans ran with? Or the magical fairy pixy dust and revolutionary of the SSD?

I know but in the end it will most likely be the on chip SRAM used as L3 cache for the whole SoC
L3 cache is specific name for CPU cache, yes the sram could be used as a cache, but not L3. It's just a name obviously...

But again why are we talking about PS5... some Moore Law is Dead shit inside that evalution video?

Desktop Zen3 will have 8x more L3 cache available per core than next gen consoles and 2x more than desktop Zen2

PS5 and XSX = 2x4MB split 8core
Zen3 = 1x32MB unified 8core

That means each core will have access to full 32MB unified cache

I much prefer Paul over Rich...
He tries to explain things a bit more.
Paul's video's have a Sony bias to them though. He has way too many PS5 secret sauce videos. "Insiders" giving him the scoop on RDNA 3 and now Zen 3 nonsense. He does have that accent though that works for these type of videos. Even though he calls the SOC (system on chip) a sock.

I meant to say he is probably seeing the on-chip SRAM being used by the CPU & GPU & thinking that PS5 will have a larger L3 cache. I guess this would be L4

Actually he is very neutral. He just has more infos about PS5 and people ask him much more about PS5. On the other hand Rich is very biased towards MS, always has being. DF have more info about Xbox because that info often comes from MS, not insiders, they are directly fed by MS. They always had a great collaboration.

so xbox hotchip analysis thread but of course some people are extrapolating from thin air ps5 is zen 3....

Its in the video that we are discussing. Try watching it first might help.

Paul is a pC gamer, he is only interest in consoles is it gives him info on RDNA2 and PC stuff upcoming.

His leaks maybe right, maybe wrong. Time will tell. Anyway, XSX is also a blade server so would unified L3 help in that application ? MS did refer to the CPU as server class.

Maybe mS chose what they need for what they want to do ?

80ROPs not CUs , that number was thrown around simply to claim that XSX was BIG NAVI while PS5 was LITE NAVI. It was also to make XSX rasterization and pixel fillrate higher than PS5 which again ended up not true.

ok so you too only see l3 ps5 cache in this 43 minute videos about xbox ?
Is it not ironic that you extrapolated that from "By thin air you must mean discussing the content of the video the thread is about."
The very thing you accused others of doing.

But are you denying or going to ignore that unified l3 cache was discussed 11 minutes into the video.

This is a topic about a long video. People can't be expected to disuss all of the video in a single post. That's not how normal discussion works.

If I think a person has nice legs, you pointing out I didn't mention their eyes doesn't invalidate my statement.

Pointing out the reasons you disagree would however be adding to the conversation. No need to play the victim.
Join in and have some fun. Otherwise why even bother right? Life's to short to waste on upsetting yourself over other people's opinions or discussions that your not into.

Ms pushing those dual purpose server use is cool though. Suits their agenda I reckon.

Nothing from you "the ultimate xbox fan" is credible.

You can see what you want to see, but it is not that simple as "they are equally capable i guess".

Maybe they are, maybe not. But nothing is 100% sure until gen starts.

Sony is after all hardware company with decades of audio experience so their solution can be still more/different vs xbox.

Maybe both wont offer anything special and all are disapointed.

Silly to call anything 100% certain before gen starts and games show it

Maybe it still is.

Tempest was designed like SPUs in Cell that can handle thousands of positional audio channels.


It's based on AMD's GPU technology we modified a compute unit in such a way as to make it very close to the SPU is in PlayStation 3.
