NX Gamer: PS5 Full Spec Analysis | A new generation is Born
- Thread starter Equanimity
- Start date
Embarrassing post. I feel bad for the mods having wade through all this console warring garbage flooding in the forum right now.
Why though? I mean, there isn't that big a gap to close to begin with... so why is it so hard to believe that something that's twice the performance of something else would make some sort of difference?
I'm really curious to hear what benefits people really think that the XSXbetter hardware bits would bring to the table and how they would present.
I mean... its currently beginning to sound like the XSX is like 50% more powerfully something.
Lol... goes to show how informed you are. Variable frequency as sony is doing it with the PS5, is a new thing.
Here's a shocker... even the XBX (and pretty much every other processor out there has a variable frequency. Not like how sony is doing it though.
Shh, don't tell him the gap in performance between the two is actually smaller than the base/mid-gen consoles.
I think they're both excellent in-depth break downs worth watching tbh.
Have you even seen the DF direct on PS5? They go as far as claim that the SSD is so fast it could theoretically be used to offload some RAM functions. That's an even bigger claim than the ones in this video.
He's made this determination by asking developers what they need to make the games they want. I think it's a good approach because this is what was done for the PS4 and resulted in fantastic games that was much more straightforward to program for compared the PS3.
Yeah that's a weird claim considering the RAM runs at 50-100 times faster than even this magic SSD. You could fill and empty it in couple of seconds, but that SSD is no match to actual RAM functions.
I didn't get it myself, but I'm no DF wizard or developer, so I'll leave the technical dissections up to them 🤷🏻♂️
We'll probably get some tech demos released as games just to show off the capabilities lol.
Maybe another open world superhero game where you can run of fly really fast and because of the SSD, you'll never be able to outrun the rendering into nothingness.
Makes sense. The SSD doesn't have to as fast as GDDR6 to offload some low priority OS functions. 5.5GB/sec is plenty fast, how fast was the DDR3 in PS4 Pro?
Inside PlayStation 4 Pro: How Sony made the first 4K games console
On PS4, apps/OS HAD to be in GDDR5 because the hard drive was too damn slow. For the Pro, Sony slapped on some cheap slow DDR3 for it. Perhaps with PS5, the SSD is fast enough to serve a similar function.
Didn't he also make a calculated gamble with the PS4 and GDDR5?
Maybe there's a use case for something that occupies a lot of space but doesn't need to be as on-demand as RAM can deliver?

Cerny: PS4 8GB GDDR5 RAM Was Decided in Very Final Meeting

At this point the main question I have is how each console handled next gen game development. What bottlenecks and limitations are there. What has been put in place to make game development easier and more efficient. And, once we have an idea of that, what are the overall advantages of each console and what things does each allow game developers to do that the other doesn't.
I can't even begin to answer these questions. The XSX has more horsepower and is a great piece of hardware, but the more I read and watch videos the more I'm appreciating Sony's approach. I know people are getting very sensitive about labeling the XSX as a brute force machine because clearly it's more than that, but it seems like the overall approach is just more power, better stuff, and in general safe. Very, very powerful, which is a gamble, but a fairly straightforward design.
Sony, on the other hand, seem to be trying to push forward some innovations in hardware that could lead to game design changing (likely limited to mostly first party though). Putting in multiple chips for specific tasks to make things run smoother. An SSD that is significantly faster than the XSX that allows for no loading and can alter how games design around that (and possibly having more RAM allocated). Even the audio chip - XSX has a custom chip, but Sony's seem to be trying pushing things even further and who knows what standard it will set. The idea of individualistic sound settings that aren't tied to specific sound systems is rad.
Of course at the end of the day it might be that there are limitations on the PS5 that the XSX simply doesn't have because of its overall power. My best guess is the XSX will always have a slight edge in the graphics department but that the PS5 will surprise people with ways in which it is better. Will I be able to tell? Heck no! But it is interesting to listen to the knowledgeable people discuss this.

Just as an aside 5 GB/s is not enough for an OS. You'd be getting hitched every time an OS function swaps into main memory.
DDR3's slowest speed is about 1 GB/s faster.

Im very very impressed by the PS5... you have that SSD... that at this point needs no introduction, the thing basically has testimonials from literal devs that swear it's a gamechanger for next gen. Then we have all those co-processors and custom chips on board. Very impressed Sony didn't just throw more horsepower at their problems, they created a smart console thats efficient and does some efficient backend thinking making devs lives easier. I agree with Andrea Pessino when he says a year from now, some are going to feel very stupid arguing about TFlops because they will realize why Sony did what they did. And... if you watch the Cerny presentation again... look at Cerny's reaction when he says "we have a responsibility to be cost effective " or something along those lines... they will undercut the Series X in price. And the Series X will be $500-$600 dollars.
What Sony designed would be an absolute steal at $400-$500

Very good post. More reflective of the reality of the situation than trying to directly compare marketing numbers alone.
With compression, were talking typical throughput of 8 to 9 gb/s. That's plenty fast enough.

Yeah Cerny knew what he was doing with those suits in the room.
But I meant this as well...
Xbox One Vs Playstation 4 Hardware Performance & GPU, CPU & Memory Analysis
The XBox One and Playstation 4 hardware specs have been unveiled, will Microsoft regret its decision using DDR3 in its machine. In this article we invesgiate
www.redgamingtech.com
"Sony had bet that GDDR5 manufacturing would have been smooth enough by the time the PS4's release that memory modules large enough to be 8GB on the machine would be possible."
"The Xbox One however takes a different design. Due to Microsoft designing the system to use memory intensive applications (all of those media capabilities don't come cheap) they needed 8GB of RAM. They decided to play it safe and go with 8GB of DDR3. "
No, we're not. Those kind of speeds will be common with art assets but not the OS itself. It'd have to be decompressing and recompressing almost constantly which would limit kraken's utility utility for you know the game assets. Not to mention how often it'd be writing / rewriting on the SSD.
the most they'll do is use the SSD for quick resume leaving that segment of memory free.

Look...I don't think the reserve for the OS will only be 500 MB. However 1 to 1.5 gb is not at all unrealistic in this scenario.
I am just about to watch, but doesn't this not make any sense at all because then you would not be able to receive any notifications, trophies, messages, etc. If the os was not in ram?
I think theres things Cerny hasn't stated yet. What if theres a seperate pool just for OS, that wasn't mentioned in the stream? But I think.. the SSD is so fast, it's entirely possible their using the SSD for the OS also. I honestly think this is why the SSD number may be a bit odd.. maybe Cerny is giving us just the balance of the SSD gigs after OS and an overhead for them using it for a multitude of other things.
Is it? Ram is like 50x faster plus I feel like they would have mentioned an obvious advantage on the spec sheet or during the presentation.
Something I haven't seen mentioned is the life expectancy of the SSD. They can't really use it as a be all end all solution because it's going to deteriorate way faster than usual.
No, cerny's words on the SSD size heavily implies it is the real size, not the leftover size excluding Ram.
I got the strong impression that the SSD is 825GB as that's the size that interfaces optimally with the 12 channels from the IO controller. It isn't some arbitrary value left after an OS install but a key hardware requirement.

I don't really follow the logic behind the 15.5 GB RAM discussion. I understand why he would say you could offload the OS to memory, but why would that not be possible on XSX? It would just take 2.3x as long, so about 1 second instead of 0.5, right?
He spent all of his Xsx deep dive downplaying teraflops. No discussion of RT, VRS, SSD, Mesh Shaders. Personally I don't find that being objective.
Last edited:
Hardly...he literally gave concrete examples of why teraflops are just one parameter or variable of the entire balance of system. Something that most people still seem to not understand. Teraflop number is not the be all end all, just like how SSD speed isn't either. The final performance you get depends on how the entire system is set up and how the different components interact with each other.
I'll gave you that, but a deep dive only explaining teraflops (rehash of an old video), without actually talking about any of the console's features is not a deep dive.
Hope he makes a proper one in the future.
Like I typed elsewhere, on an informed hunch that my colleague John also alluded to, it does not actually work like that. Devs have to choose.
Didn't PS4 Pro use additional DDR3 Ram for some tasks?
There's 1GB of Extra RAM in the PS4 Pro, Mark Cerny Explains Why - PlayStation LifeStyle
In a new tech session this week, Cerny walked through more details of the PS4 Pro RAM, including what the extra 1GB of DDR3 RAM is used for, 8GB GDDR5 RAM.
www.playstationlifestyle.net
It's not cost friendly, but they may use 1-2gb DDR4 do help OS works, while game utilize more GDDR6 Memory.
Man, stability updates on PS5 will mean so much more in the future :)
Reading about SmartShift, it seems that this should be dynamic? What's the point if developers have to code for it. The vast majority of them would just prioritize the CPU.
Can you expand on the "informed hunch"? Info from a source or guesswork/research from other products?
Yea it definitely wasn't a proper deep dive like the PS5 video
If you don't have anything to say then you really shouldn't.
In the video, he analyses the ps5's specs. A click is a valid click, nobody is getting baited into anything they didn't expect.
You still have to take in account a 1TF machine with a HDD as a baseline. Can't do huge open worlds with insane draw distances with no loading screens through wich you travel at enormous speeds without your game completely falling apart.
What gap do yo refer to exactly? The minor (20%) GPU gap or the 125% IO speed gap?
When will people understand the biggest difference between these to machines is, BY FAR, the SSD?
