He said 10% reduction in power only needed a few percent reduction in frequency.
The developers don't need to worry about that.Add to this the "power control" and variable frequencies of the GPU and CPU. The more I read about it the more complex it seems. It just seems like it will require more work from developers to optimize their games and get them running the way they want them to run.

I see that as happening on a lower layer.
In this image, you see that "Power Control". That's what handles that, not the developers.Add to this the "power control" and variable frequencies of the GPU and CPU.

Look at all the excuses going round ... PS5 this gen is XB1 last gen ... Deal with it.
Sony prioritized PS4 BackCompat and COST above Power .. Infact if even placed Bandwidth ahead of Power.
And even with those 4 things, BC/Cost/Power/Bandwidth, XboxSeriesX takes 3 of those crowns ... Imagine if XSX also ends up taking Cost too..

Yeah no offence to the guy but i hope he doesn't come back ever, tricked the entire next gen speculation community for god knows how many OT's.
Kobrille said it right, fake insiders hurt the PS5 the most.
It's been a really tough gen for you hasn't it?
Christ how embarrassing.
I have to agree with everyone, i have no clue why they did this.
They should of did a conference, open up with awesome games, and then at the end slap the 10.2TF number on the screen and tell everyone good night. This is bringing them wayyyyy too much negative attention.
Concentrate on what you are good at; exclusives.

You're arguing 8.5% gpu difference will be the same as Cell vs Normal processing lol.
There will not likely even be resolution changes like this gen. And that was based on 50% gpu difference.
Depending on the complexity of using the faster ssd, we'll have to see what 3rd party devs actually do.
It'll be night and day compared to PS3/60 days
No, if anything that Xbox Series X sounds closer to a PC while the PS5 sounds more custom. Starting from the SSD, GPU, CPU, I/O, Audio, where as what Microsoft seems to have done is taken the building blocks of RDNA2 and make some smaller customizations (software stacks) on top of it. The only bit where I see the Series X is custom is that the weird memory setup (again) and to meet the 16GB goal, they'd to go this route and manage it in software. If not they would have ended up with either 12GB or 18GB RAM. So the customization bit came out of necessity rather than the innovating for power.
You are also wrong in assuming a bigger chip at 1.8GHz versus a smaller chip at 2+ GHz will draw less power. They may end up same if not more.
Even with the same price they won't beat PS5 sales worldwide.
I am mainly a PS guy and used to be quite fanboyish about stuff like this . The old me would have been really salty about this.
Now that i own an X with 2 years worth of gamepass , I honestly don't care about which one is more powerful , both consoles are going to be great in their own right.
PS5 is gonna continue to be my main console for MP games , people outside the US and maybe the UK don't realise how little people care about Xbox in other regions . Here in the middle East it's almost non existent, I don't know anyone who owns an Xbox except me.
Best Xbox can hope for is winning the US market and even then i don't think it's gonna be a repeat of the 360 Vs PS3 gen.
Seems kind of farfetched. This is nowhere near as being another TVTVTVTV situation.
lol you meanie
Cerny is awesome but this wasn't his best speach that's for sure.
Cerny mentioned that the power supplied to either CPU/GPU fluctuates at around 10%, we know thatAdd to this the "power control" and variable frequencies of the GPU and CPU. The more I read about it the more complex it seems. It just seems like it will require more work from developers to optimize their games and get them running the way they want them to run.
power ∝ frequency ^ 2.So if, say, the power of GPU drops to 90% of the peak level, then we get roughly
sqrt(0.9) * 2230 ≈ 2115MHz, which isn't bad at all.
I don't think transfer speed will make a huge difference in real world performance. Take a look at this video comparing a 870 ssd vs 970 Nvme. The nvme is 7 times faster but only shows one or two second faster loading times on games. The PS5 transfer is twice as fast on paper compared to series X. Can't wait to see how this translate to real world performance by digital foundry.
M.2 NVME vs SSD vs SSHD vs HDD Game Loading Times
M.2 vs SSD vs SSHD vs HDD Game Loading Times. Welcome back guys, I thought it might be a good time to do an update to my M.2 vs SSD game loading times compar...www.youtube.com
cerny literally covered that in depth in the presentation. They aren't using pcie3, they have dedicated hardware (a lot of it) to help with decompression and transferring without impacting CPU efficiently. And more. Worth watching through or reading the euro gamer article
Yeah, disappointing is the right word. I bet that it's a great console and awesome hardware for devs. But I can believe i how much it is lagging behind ms in so many areas even though Sony is the king of this gen. The variable frequency sounds like a fancy excuse boost mode to talk up their numbers on paper.
Again, if someone told me these specs a year ago where even an sata SSD was being laughed it, I would've melted, but seeing what MS is doing I can't shake the feeling that this is not Sony's best job. This gets especially sour when looking at their joke of BC. While Microsoft is testing unlocked framerates and boosts to resolution, Sony is giving us the top 100 without any real enhancement.
Let's hope my favorite games are in these 100. Is Nier Automata a top 100 game? I really wanted to jump into Nioh and test the different modes to see how they would run, but now I don't even know if the game will run.
I was suspecting this during the generation and there was a post about this here on era but I'm starting to feel like investing into the PlayStation eco system is a bad long-term investment since they really don't care about their legacy content while Microsoft is pumping out Ninja Gaiden at 4K/60 and AI-HDR.
Add to this the "power control" and variable frequencies of the GPU and CPU. The more I read about it the more complex it seems. It just seems like it will require more work from developers to optimize their games and get them running the way they want them to run.
variable frequency is good for temp, no? Most games won't require capped frequencies.
Hope you get banned. Honestly cringed reading that post.
I mentioned this in a reply. Sony has a custom storage solution but so does Xbox series X. We will just have to wait and see how it translate to real world performance by digital foundry vttech etc. I predict loading times will probably be a second faster on ps5 than series X. But everything else Series X will have the advantage. This is my prediction.
You've been waiting to tell others to "deal with it" haven't you? lmao
I was hoping for someps3 bc when he brought it up. :(
Eurogamer suggests it may require some additional work.
"On the face of it, PlayStation 5 delivers a ton of power, but there does seem to be an extra onus on developers to optimise to these new characteristics"
The ssd-tech in the ps5 sounds promising but in the end only exclusives will benefit from it as third party will develop games with slower tech in mind. Right now I don't really see the benefit of a better ssd except better loadtimes. But I am happy to see what devs will do with it.
Oh man, full BC is not going to happen when their priority is to test PS4 BC for most titles.
precisely! In the past I brought up an example of a well-read older colleague who FOUR YEARS after the XB1 reveal STILL thought there was no game sharing, no used games, and always online requirement. This guy knew enough about gaming to buy a PSVR but doesn't live on era and reddit and so mainstream marketing did matter.
You are 100% right that marketing and initial messaging absolutely do matter for a really long time.
'yeah both sides seem to have focused on SSD, just with higher baseline raw performance on ps5.
both spent a lot of time and effort on maintaining that performance and not wasting CPU cycles for decompression, or memory bandwidth by moving data around more than necessary
while Sony has higher raw speed, I'm curious about whether some of the MS directstorage features and predictive texture fetching etc might mitigate that difference in raw power - or whether Sony has similar features too.
both will also make PC support challenging - you're potentially burning multiple CPU cores to keep up with transfer throughput and decompression
Only it's absolutely nothing like last gen and you should stop trolling. For now, on paper the PS5 is more innovative and even just comparing GPU power (which is a false comparison but whatever) the difference is smaller than the PS4/One situation.
This. Was. A. Tech. Event. For. The. Development. Community.
Why are people saying it's a missed opportunity because they didn't show games or the controller/console?! It was clearly signposted as a technical discussion, you can't complain it was missing something that had no relevance to the event and was never likely to be there.

Playstation is still a far stronger brand globally with the PS3,PS4 being recent examples.
That's what I expect Microsoft will do at all costs. XBox Live and Game Pass Subscriptions will compensate the loss of each hardware sold.
