No, none of those things can be easily turned down. That is the reason so many developpers are not happy at all. There is no magical switch in any compiler that says "Now do it for1080p only".

The Play Station CPU has variable frequency at up to 3.5 GHz; so you should probably compare all with that in mind. https://play4.uk/technology-news/xbox-series-s-cpu-faster-than-the-ps5s-cpu/#:~:text=Xbox%20Series%20S%20CPU%20Faster%20Than%20The%20PS5%E2%80%99s,faster%20than%20the%20CPU%20of%20the%20PlayStation%205. https://www.psu.com/news/the-xbox-series-s-cpu-is-faster-than-the-ps5s-cpu/ https://www.t3.com/news/xbox-series-s-has-faster-cpu-than-ps5-and-supports-ray-tracing And I can go on but you get the point (and if you bing xbox series s cpu faster than play station five, you see all major outlets there). The "up to" speed from Sony is very likely without SMT and everyone is probably agreeing with that even without knowing 100% for sure. So it is probably more: Without SMT: Xbox Series X = 3,8ghz With SMT: Xbox Series X = 3,6ghz But it does not matter anyway. I believe the bottleneck in the S is probably going to be the memory if you are looking to point out something. While they will require less memory than the X (textures?), going from 12GB to 7GB (some rumors are talking about 6GB) for games will be the weakest point. |
or instead of all that mental gymnastics......
The more logical conclusion is the 3 sites you mentioned above (link) that claim the Xbox Series S cpu is faster, were just wrong.
They made those comments before microsoft announced the CPU speed of the S.
Sony have said the PS5 is 3,5Ghz is with SMT on, running full load (so the series X cpu is 100mhz faster).
Also supposedly the Xbox Series S also has variable rates...... the series X has locked clocks, the S doesnt.
(I Believe I read somewhere) (its just ignored or never mentioned)
| JRPGfan said: or instead of all that mental gymnastics...... |
No need for mental gymnastics (at least not on my part), you should probably read the rest of the response regarding what I posted after that which talks about the "always-on" SMT and this is actually where the variable rate is not, not the S... "SMT always on at 3.5ghz with variable frequency". Believing that then 3.5ghz is the average speed with SMT makes very little sense.
As for the links are the 3 first ones in the list when you search for it. Basically the whole industry is agreeing and virtual nobody is believing that the S CPU is slower. And yet, your "logical" conclusion is that they are all wrong and you are right.
Oh well, maybe it is the case; after all, everything is based on assumptions so until this is proven (both ways) we can only go with what we know or read (as some specs are not really more detailed than a single liner).
And maybe when Sony says "3.5ghz with SMT on all the time with variable frequency" it means something else and the 3.5ghz is an average, not a max... Don't know.
Digital only..l sounds like 69$ e-shop games all day long.
| the-pi-guy said: Again, as he said those articles were from before the XSS was even announced. Tom Warren was under the impression that the XSS was the exact same as the XSX. Microsoft corrected him. It's 0.2 GHz slower. PS5 will run at 3.5 GHz most of the time. 3.5 GHz isn't some random maximum that it rarely hits. It spends most of the time there. And if you down clock the GPU, it can spend all of its time there.
Those are two separate sentences saying two separate things. Both sentences are correct. They're not correct if you combine them. |
First: 2020/09/10 is after the Series S announcement.
Second: I am talking about 3.6ghz/3.4ghz and every article I linked is talking about 3.6ghz/3.4ghz not 3.8ghz; so not sure what you are talking about the "Microsoft corrected him". Unless you are going to say that the CPU is 3.4/3.2...
I'm talking about assumptions based on what we know (and keep telling how nothing is sure) and you state your points as "we know for sure" from a one-liner (one sentence too by the way from YOUR link and any other link or source I cared to read or look at following your response "8x Zen 2 Cores at 3.5GHz with SMT (variable frequency)").
I'm done, you are right: CPU is faster, all articles are wrong and variable frequency means most of the time.
Good for all of us anyway, still getting a play station five digital when it will come out.
| the-pi-guy said: 3.5 GHz is with SMT. It just won't run at 3.5 GHz 100% of the time with 100% of games. |
Why would it do it, anyways? Are you really thinking there will be any game in the next 2-3 years that will max out all 8 cpu cores all the time (hint:one of the eight cores will not do that, ever).

You're inventing bizarre assumptions that the PS5 has to be with SMT off and must be slower based off absolutely nothing. And taking information from bad sources. And I'm taking information from what Cerny and Digital Foundry have said as well as actual devs I've talked to. >CPU is faster, all articles are wrong and variable frequency means most of the time. PS5's CPU is generally a tiny speck faster. Yes clickbait articles aren't the most reliable. No "variable frequency" doesn't mean most of the time. Cerny and devs have said that it spends most of it's time at 3.5 GHz. The frequency has to be capped, otherwise it would go higher. 3.5 GHz was picked because the heat matches the heat of the GPU (which similarly had to be capped in order to work, as the chips logic runs into issues faster than that). |
Bold: No I am not, you are making this up. The SMT off was in my first reply and then we corrected it and I never brought that again. You are sticking on that when it has nothing to do with the past 5 replies or so...
To be short, based on that (Sony official specs) "8x Zen 2 Cores at 3.5GHz with SMT (variable frequency)":
My assumption: I assume 3.5ghz is NOT the 100% time speed (and will not be the average) and the S CPU is probably faster overall with its fixed SMT frequency (and obviously in some case faster depending on the thread requirements, i.e: no need for SMT).
Your assumption: You assume 3.5ghz is close to 100% of the time and variable frequency is not really relevant; therefore 3.5ghz should be considered as "all the time".
That's all, the rest is just opinion. And nothing in that in "invended bizarre assumption"... It is pretty fine to believe that based on what we know. Assuming != hoping/believing in something by the way. Personally the better it is, the better the games I love will be (I'm a huge fan of Horizon) but I'm sorry if I do not share your believes on the CPU front, I simply do not and one-liner stuff like that tend to be there for a reason in my book.
