Topic: PlayStation 5 --OT--

I hope PS5 games will be supported by Limited Run Games / Strictly Limited Games / eastsoftasia / any publisher from digital to physical. Some indie games are hidden gems for me.

The PS5 supports 256 bit instructions and these use a lot of power. I wonder whether they’ll be less used now as they cause the the CPU and GPU to down clock than they would’ve been if they had increased by power consumption.

@Ryall
Definitely, I think power is constantly monitored and frequencies depend on it right? That's why they can target an efficient cooling system. (I think?)
Amusingly a lot of insecure people try to downplay the ps5 and question what Cerny said whereas it the only info we have. So why question it ?
I watched Brad Sam's video recently and that's embarrassing, especially the comments.

@JJ2 Basically he was saying that with the technology used in the PS4 Pro, they would need a much bigger GPU to match what the GPU in the PS5 is capable of delivering. The 'size' (as in number of CU's) is only part of the equation when it comes to the TF. It's calculated using FP32 but if they used the smaller FP16, essentially doubling the amount of instruction the GPU could do, the PS4 Pro would be a 8.4TF console - it can accept FP16, unlike the XB1X which can only handle FP32 operations

Flops are Floating Point operations per second so the frequency, how many times it cycles per second is important. An Identical GPU, same number of CU's/Shaders, running at 2Ghzwould have double the TF as one running at 1Ghz because it has double the amount of cycles. Its like a printing press that prints out a 20 sheets a second, if you speed that up to print 40 sheets a second, it doubles the amount of work it can do per second. Another way of course would be to add a 2nd machine so you have 2 machines both printing out 20 sheets a second to give you the same 40 sheets per second rate.

With modern GPU's, the pipeline is much more efficient and less lag between components so the overall effect is that they don't need as many 'Flops' to achieve the same results as older machines. They aren't waiting for micro-seconds for the instructions for the instructions to be sent to the GPU or waiting for certain operations to be carried out before the next instruction can be carried out so you get more work done. Of course we are seeing a much bigger increase in the GPU's too.

In a recent DF video, they were looking at RDNA1 and the 'rumoured' Project Lockhart Xbox. At face value, it sounds 'weak' compared to the Pro and X with just 4TF (with the Pro at 4.2 and X at 6TF) but RDNA1 in a PC at 4.2 TF was delivering comparable performance to the X. RDNA 2 is more efficient again so would offer an improved performance on top of RDNA1. What that means is that at ~10TF, the PS5's RDNA2 GPU would give more than 2.5x the performance of the 6TF X and probably close to 4x the performance of the PS4 Pro despite the TF rating seemingly much closer. According to the numbers, the PS5 isn't 2x the X or more than 2.5x the Pro...

I think that's what Mark Cerny was alluding to - that you would need a massive GPU if they used the same GCN Architecture that the Pro used in the PS5 and that would need to be at least 16TF's to deliver the same performance...

@Webhead I find that hard to believe considering the guy reposting this works for windows central so already there's bias there. It also goes against the general feeling among the devs who seem to be more excited by PS5 then XsX. It just seems like someone trying to find a negative reason for Sony not showing games yet.

@WebHead sounds sketchy. That's not the general talk from devs from what we know so far and he works for Windows Central, or the source does more like, so I'm very doubtful. And that sentence about the tower and copying MS isn't even coherent. They are worried about being accused of copying MS so they need to redesign the PS5 to look more like the XSX trash can, COUGH COUGH, I mean tower. I've reread that a few times and every time I read it sounds like they're worried about copying so they're making it look more like the competition, so copy more to avoid being accused of copying.... sounds right doesn't it? No, that sounds fake. It feels like it's just trying to bash. Heck, I haven't heard any of the so-called rumors from people in the know, they's allegedly been going on for months.

@WebHead And here's another quote from the source after he got called out for having a history of PS doom tweets.
"Hate to break it to you, that still does hold true on console engagement and is known. It's not that PS was ever doomed, but it is a more casual console than the Xbox at this point. That is pretty well known."
Hahahaha no. Just because it outsold the Xbox more than 2 to 1 doesn't make it more casual.
Yeah, it's a load of nothing.

@WebHead
Seems to me a lot of people are just being insecure. If theres really a heat problem, the form and making it a tower wouldn't fix it. Sounds like people who dont understand what Cerny said and talking about heating problem.
I dont believe it for a second

@WebHead Whilst it is clear that the PS5 will not be able to run everything at maximum frequency the whole time. Sony is aware of this and therefore the PS5 is unlikely to have issues with overheating. Apparently the PS5 development kits allow you to choose what you want down clock right at the start and then developers are targeting fix performances. Apparently in almost all cases they choose to down clock the CPU and run the graphics at maximum frequency.

Sony have made different choices from Microsoft. But at this stage it’s difficult to say which will result in the better console. I’m fairly certain both will reliably work as intended.

Idk too much negative news lately.

I hope sony lets you back up PS5 games on an external HDD and then when you want to play you can transfer it to the SSD. Im not paying $300+ for storage.

@WebHead Yeah think have have already said current external drives will be supported, just to play most PS5 games it will need to be o the internal PS5 SSD.

I dont know about you guys, but I absolutely love the DualSense. I hope the console has the same look and futurist style. Some people will hate, I dont care haha
It's a gaming console, not a mini PC 😀

@JJ2 it has grown on me for sure.

and a white console at launch would be awsome,usually those only become available later on in it's life span.

My Pro’s white and it looks a lot better than the black. The material means it doesn’t get dirty either.

I would prefer it to be black so that it blends in with the rest of my stuff, but if that is the worst thing about the PS5, then it will be happy days.

I wonder about PS5 game retail design.
What color scheme for Top banner of PS5 cover ?
PS2 & PS3 = Black, Red (Greatest Hits), Yellow (Platinum / the Best )
PS4 = Indigo
PS5 = ???
I prefer Baby Blue color like Wii U. 😊

@Arugula Do you think first party games will be black and white also?
