So from what I'm gathering, it's basically 15%-30%~ percent weaker in GPU/CPU than XSX (with it being variable and all that). I wonder how much influence will the faster SSD have on game design and immersion but I don't see it outweighing the disadvantages. I'm pretty sure it'll sound like a jet engine so that's the other flaw lol.

And yes, felt like a terrible way to introduce the system to the masses. Hyping people up and streaming this was a bad idea.

3.8ghz vs 3.5ghz =  ~7.9% differnce in cpu speeds.

10.3 Tflop vs 12,15 Tflops = ~15% differnce in gpu compute flops.
(however theres small advantages to other parts of the GPU running faster speeds (PS5 gpu parts clock higher), so its probably less than 15%)

It shouldn't be close to a 30% differnce, its looking more like a less than 15% thingy.

Honestly I said before, I dont really care how fast things are.
I want cheap.... If sony can be 100$ cheaper than the series X, thats a win in my book.

Sounds like both will cost $499.

I must say I do prefer the expandable storage storage on Xbox Series X more. I prefer to spend a bit more on made to fit accessories and the XSX memory cards look sleek and take the hassle out of deciding what storage to get (hopefully sony produce a memory card of their own)

Sony certainly will have partner solution with PS5 stamp, they have that even for HDD where that isn't even necessary.

In that case, Xbox won the design choices imo.
If their priced the same, and the xbox series x is like 15% faster, that means they spent their budget better.

I still think Playstation 5 will be cheaper.

Why?

36 CU vs 52 CU = ~45% differnce.

256bit bus vs 320bit bus = ~25% differnce.

Thats alot of "space saved" on the chip side of things (for the playstation 5).
A smaller chip means cheaper to produce (the chip part atleast).

It doesnt rule out PS1,PS2,PS3.... but if it could do that, I expect he would have mentioned it.
I was hopeing they would talk about PS3 as well, and say it could do that.

Now im kinda expecting that it maybe wont be able to.

I'm asking why expect that? Ps3 and older games arent veing sold anymore.

Xbox has plenty 360 games on the store. Some OG Xbox titles too. It’s pricey relative to their age, like I saw Alan Wake for $20 CAD. But it’s there and available.

within 20% *15% difference between the "Tflop" count, with a lot less CUs at a higher frequency. So price may be a lot smaller and the lost performance may not be that visible.

10,3 vs 12,15

However the GPU parts of the Playstation 5, run at higher speeds.
(which effects other things than just the Tflops numbers)

So differnce is less than 15% imo.

Ram 520 GB/s vs 448 GB/s = ~14%

However I dont think it ll matter, both will run 4k games.

Should have said under 20%. But yes on the direct math it is 15% lower, but that may shrunk more due to higher frequency and also the colaboration of the faster SSD. Still same ballpark, and for me a good trade-off on cost versus performance when they can have so many CUs less but still deliver within 15% performance.

How do you get to 30% weaker?

PS5 and XSX seem to have the same number of ROPs. So PS5 is 2.25/1.825 times faster than XSX. PS5 and XSX seem to have the same geometry engines. So PS5 is 2.25/1.825 times faster than XSX. Gpu cache access in the PS5 is 2.25/1.825 times faster than XSX (this is a big thing for RT).

You seem to look at cu count and forget all the things around it. Good for you, but maybe slightly naive. My guess is in "conventional" games, we might look at at a 2160p vs 1920p upscaled difference, which will not be noticable to most people.

And PS5 seems to have a practical/usable implementation of HRTF as a console standard. This might tell you nothing, but a lot to the audio freaks.

So... only PS4 backwards compatibility. Well, I guess that settles it. Series X it is.

Also, they shouldn't have advertised this for everyone. This was so technical and so boring... what they were thinking?

You think their lack of showmanship was counterproductive?

And only PS4 BC???? Good to know MS has them beat on this point. So many 360 gems I’ve yet to play in my back catalog. I’m sure the same goes for those who had a PS3 

Not exactly. I the presentation was good for what it was: a talk for professional developers made by professional developers. Very technical. That's not a bad thing. The bad thing is that yesterday they said to everyone on social media: "HEY GUYS, COME TOMORROW TO SEE THE INFORMATION OF PS5!". Most people (myself included) are not interested in a presentation so technical and professional, so it was a mistake on Sony's part to announce this as an event for everyone. Because it wasn't. The average Jill or Joe will be killed by boredo.

About backwards compatibility... I was as surprised as you. Power alone makes it perfectly possible. They just had to work out a PS3 emulator, because they already have everything else. But whathever... it is what it is...

Lol wait till Lockhart becomes official if you care about saving $$

The two things I find interesting are Memory Bandwidth differences for the Vram between XsX and Ps5 and the ps5's boost behaviour.

XSX has 10GB of Vram at 560GB/s and 6GB at 336GB/s vs Ps5's all 16GB at 448GB/s. It will be interesting to see how games perform as more and more Vram gets used cause in theory, if a game needs more than 10GB of Vram, the ps5 might be a bit of an advantage depending on the situation.

The boost aspect is also kind of interesting:
https://www.eurogamer.net/articles/digitalfoundry-2020-playstation-5-specs-and-tech-that-deliver-sonys-next-gen-vision

It almost sounds like if a game is on full tilt using all 8 cores at 3.5ghz and gpu at 2.23ghz, the ps5 might down clock slightly to meet it's power targets.

"What happens when the processor does hit its power limit and components down-clock? In his presentation, Mark Cerny freely admits that CPU and GPU won't always be running at 3.5GHz and 2.23GHz respectively."

"When that worst case game arrives, it will run at a lower clock speed. But not too much lower, to reduce power by 10 per cent it only takes a couple of percent reduction in frequency, so I'd expect any downclocking to be pretty minor," he explains. "All things considered, the change to a variable frequency approach will show significant gains for PlayStation gamers."

"So how does boost work in this case? Put simply, the PlayStation 5 is given a set power budget tied to the thermal limits of the cooling assembly. "It's a completely different paradigm," says Cerny. "Rather than running at constant frequency and letting the power vary based on the workload, we run at essentially constant power and let the frequency vary based on the workload.""

"Rather than look at the actual temperature of the silicon die, we look at the activities that the GPU and CPU are performing and set the frequencies on that basis - which makes everything deterministic and repeatable," Cerny explains in his presentation. "While we're at it, we also use AMD's SmartShift technology and send any unused power from the CPU to the GPU so it can squeeze out a few more pixels."
