Playstation 5 GPU - Clearing Up Overclocked GPU & RDNA Features Confusion

The Playstation 5 will launch in just about a months time from now, and there's a lot of excitement for both Sony's next generation console and Microsoft's X...

www.youtube.com

I know this video is a few days old now, but I just finished watching it and found it really informative. I didn't it anywhere on this forum yet so here you go.

This forum caters to a more well informed crowd than say, reddit or twitter - so I find it really annoying how some resetera users are rather picky in choosing which established facts to accept and which to ignore. Like many of you, I've been following nextgen news and leaks since before 2019. I was there for the PS5 HBM rumours. I was there for the Full BC for all PS generations rumours (I really did hope that one was true). Even the github leaks provided some really informative reading for a couple of months in between the more troglodytic members' posts.

So now that we have the full tech specs - now that we know the console inside and out it's a personal sore spot that some users still insist on spouting misleading facts as if it's gospel.

RedGamingTech's video abvoe is a really great insight into how the PS5 SoC works. He explains why Sony went with a variable clock frequency for both GPU and CPU, and how it's a good thing for overall performance. While Cerny himself mentioned this in passing in the original presentation, this video goes into much more detail on that stuff. To those who still insist on calling this an overclocked GPU - no. It's not. Nor is it a last minute clock boost implemented by Cerny because he got scared of the competition. The GPU, CPU and the power delivery system of the console are all designed from the ground up for this. Instead of me clumsily trying to summarise the contents of the video here, I'd urge you to watch it. The video also goes into some other interesting next gen GPU stuff.

We've just seen a rumour from a card with 2.4GHz game clocks on the PS5 thread. If anything, the XSX is the odd one with just 1.825GHz or something like that.

RDNA2 clocks are just insane.

 

[Pheonix]

INb4 XSX clock boost via patch later.

Tried watching... the dude rambles a lot. Like, just get to the point of what you are trying to say but instead, he has this habit of rambling and talking about things that aren't relevant to the topic. And he does the same in all his videos.

 

[Protome]

I appreciate this thread but maybe I'm just cynical, I don't think this will help. The people saying those things were never saying them in good faith and a YouTube video explaining it to them probably won't stop them.

I wonder if Xbox clocked their chip that way because of the cooling that would be needed.

Is that even possible? I presume the cooling would be designed around current clocks.

Good luck saying that to the people that will say it's possible. They will probably cite the PSP as an example.

They upclocked the OG Xbox One before launch, so it's certainly possible. But given they already have the performance lead it seems pointless and I doubt they would.

It usually is but there would always been some headroom where the clocks could be increased before launch.

Can we not derail this thread when it's not even halfway through the first page? Yes, FUD about XSX is really tiresome - so why preemptively bring it up when nobody else has other than to shit up the thread?

Yep. I appreciate the thread to the extent there is genuine misunderstanding, but a lot of it is not. It's quite telling how popular the "9.2 TF!" "last-minute upclock!" "cooling issues!" fanboy FUD circus bullshit still is on other sites tailored to competing platforms.

Click to shrink...

It is possible. It has been done before. Devices have a certain amount of thermal and timing head room built in. It's unlikely, of course, because it's a ridiculously powerful console. But if you're going to say it's impossible for Microsoft to increase clocks now, that's just incorrect. Sony might even be able to. Again, very unlikely.

Beat me to it.

I think once the RDNA 2 cards come out it will be even more clearer.

Too many things point to the FUD being clearly FUD.

This too.

Honestly, this should just help ppl that are legit concerned and have questions about the PS5 make things clearer. Cant waste time or energy on ppl that post in absolute bad faith, disingenuous and knowingly spread FUD. Just best to use the ignore function.

That and bookmarks are a godsend on this forum, lol.

 

[Hybrid Rainbow]

The biggest misconception that I see a lot of bad faith posters here on Era perpetuate is this silly idea that the PS5 is really 9TF and that the variable frequency that the PS5 uses is an overclock that pushes it up to 10.2TF. 😒

Xbox One X has ~1.2ghz clock and is similar to the RX580 which has ~1.3ghz clock. It's within a few percentage points of equivalent desktop part. 1.8ghz in the console vs 2.4ghz in the pc part, is not typical.

 

[CloudsFromSpace]

Guys, the number of people who would have be lying, misleading, or deceived in order for the XSX to not be RDNA2 would be insane. Especially when it's been openly advertised as RDNA2 for almost a year now. It's RDNA2.

The one person who posted about this was clearly trolling and doesn't believe XSX isn't RDNA2.

Nobody in this thread genuinely claimed XSX isn't RDNA2. More importantly, this thread has nothing to do with XSX.

Successful derail, though.

Jesus Tapdancing Christ. No. Nobody has genuinely made this claim in this thread.

 

[Abominuz]

Funny thing is both are based on RDNA 2 but are not RDNA2 base for desktops. They customize a lot of things and leave out the stuff they dont need. I would not be suprised if it is a solutions between 1 and 2 for both consoles. But again just wait until we have more information on the features, blockdiagrams, etc

There's literally no reason for them to do it also. XSX besides the increased heat that would happen XSX only has a 315 watt power supply.
PS5 has s 35ow power supply, Giant Case and needed Liquid Metal to cool the system.

I can't see that being worth it at all when they already have the most powerful system on the market.

one ban so far that's a pretty low number tbh

It technically is an overclock. What people don't understand is that there is a difference between an overclock and a GPU that has boost. Overclock is meant to be stable while boost has way more variance.

It's definitely posssible, but we're in the world of diminishing returns. That 2TF advantage looks massive on paper but we know this will materialize in a small lead in visual/resolution, something the average consumer won't see - a clock boost won't push this advantage much further than the gap they've already created.

It's not an overclock. The boost clock is set by the manufacturer. The definition of an overclock is turning the clock speeds up past what the manufacturer set.

 

[2Blackcats]

Does he explain why there's only 100 games that are backwards compatible?// Example of bad faith arguement

I see why you made the thread but it will have no effect on the bad faith arguements.

 

[ShapeGSX]

"Overclock" is a consumer term (although some graphics card companies have chosen to use the term). Sony could never "overclock" their console because they're the ones who designed it to run at a particular frequency. It is simply running at the frequency it was designed to, and that's that.

 

[Pheonix]

It is possible. It has been done before. Devices have a certain amount of thermal and timing head room built in. It's unlikely, of course, because it's a ridiculously powerful console.

It's a rhetorical question, something like "it's not like FUD spreaders will stop with this video".

I wasn't replying to your inb4 message. Your other post definitely insinuated that it couldn't be done because the console was designed to run at certain thermal levels (which was stated in the message you were responding to).

Why bring it up at all? Is it like a pre-emptive strike sort of thing? I haven't been keeping up with the news from the battlefront.

On topic, it seems like the chip was designed to run that fast and Sony found a sufficient way to cool it. I have faith in their design so no worries over here.

Ok.. all's forgiven. I was replying to someone that said that. And yes I could see how what I said could be interpreted as such, but that wasn't my meaning. I just knew that the narrative of this thread would become focused on an XSX overclock.

I think the best thing to do is wait till the cards are actually out. A lot of these leaks has been off this year.

Personally, though, I am buying it..this very thing has been a point of conversation in another thread before this info even started making the rounds.

Wait there are people still trying to spread fud on the gpu that it's not RDNA 2?

RedGamingTech is not someone you should take seriously. Just my 2 cents.

Larger chips with more CU's are typically clocked lower comparetevily. Has been like that in PC space for a long time anyway. Afaik a 2080Ti has a lower clock speed than a 2070 or 2060.

Series X has a 'much' larger GPU in the Soc with 50 CU's compared to the 36 in the SoC in PS5.
