Nvidia Driver 510.39.01 Unlocks GPU System Processor Performance Enhancement

Yes! CPU is a wasteful [expletive] when it comes to executing GPU related work. This means I will no longer have to use stupid tricks like this to improve CPU power efficiency: https://abload.de/img/screenshot2022-01-201v8j64.png

Here are 21 games... and my initial sentence (in most games the CPU has to be severely underpowered to be too slow for the GPU) seems to stay unhinged: [youtube=2ol9UW_jjfc]

And that's with UNLOCKED frames. Some people do run their games with no upper limit; I personally don't.

southamptonfc:

You'd need to quantify that. In BF2042, going from a 12900k to a 10700K (5gz 8 cores!) results in a 28% reduction in minimum framerate @ 1440p. That's huge.

well yes... if someone is silly enough to keep their CPU underclocked all the time, even during CPU limited scenarios. while expecting same performance(!?) OTOH there are plenty of games and use scenarios where you can shave ~30W from CPU with virtually no perf. downgrade. This (AND MORE) is what GSP will be doing automatically.

21 old games. The more modern ones (4 years old!) all show performance drops with a slower CPU.

No idea what you're trying to say. The benchmark I linked isn't for an underclocked 10700k. It just clearly shows that the latest games benefit from the fastest CPUs.

That wasn't even directed at you. The response is always directed at person that's quoted. if you still don't understand, re-read the [expletive] of it 🙂 TLDR; I am saying that in FPS limited scenario(vsync or othwerwise) differences between 3 and 5GHz diminish even more than what's in his benchmark vid.

I've re-read it several times. You quoted me and then twice said you weren't replying to me, your response was actually directed at the person being quoted. Which was me! 😕 😕

his response wasn't even relevant, it posted performance numbers, not the statistics for pairing CPU X with GPU X. fact is many people are pairing high end gpu's with older cpus.

intresting something that supposed take workload off the cpu and put on gpu, and been around for few years and been withheld by nvidia, Yah they dont want give free performance gain in anyway special if it can be done in drivers, I think they like money people throw at them when just jack power up for gains None the it may help it may not from what i seeing.

PS. Laptop CPUs are just as fast as all but the fastest of the latest generation of desktop CPUs now.

Frequency wise, yes but there are other features build into CPU's that give a fast systems, that is where laptop CPU's still fall behind.

I'm unaware of these features. My wife's new Dell laptop is faster in single threaded super pi than my overclocked 9900k.

You have to compare new desktop vs laptops CPU's. Still slightly lower base and max boost clock, lower cache sizes, slower memory, older PCI-E gen support, less cores and threads etc. It all stacks up. They didn't state the laptops complete specs in the video either. Apart from that, while using Windows 10 I have seen a lot of modern games running with the CPU core on my 5900X down at 3.7 GHz (actual gameplay) while barely having any load, it would only went up to 5GHz + when running cutscenes and while loading. The GPU still seems to do majority of the lifting, hence why I have my doubts in how useful such an "enhancement" might be.

Most of the improvements don't make as much sense on desktops (where constraining CPU power consumption isn't as important) if you really understand what they are doing...

Whenever people say "your CPU is fast enough, you don't need these CPU optimisations", they're full of crap. If something lowers the one of the largest issues with modern PC architecture (which is, guess, CPU overhead), we should always, always WANT it. All the rest is corpo speak so Nvidia can charge for a piece of hardware sitting there since Turing, in the most expensive GPUs ever made.

If I let Windows manage my processor and don't peg my 9900k to 5ghz all cores, I see a significant drop in FPS in games like RDR2, BF5, FarCry 5. And that is running at nearly 4K res with a 3080ti. You should check how many FPS you're losing.

Since a driver is the one that unlocks this embedded GPU hardware feature, then it should be possible to modify current Nvidia desktop drivers to also enable this GPU System Processor on desktop GPUs.

That's it? Just a simple no? No explanation why it can't be done when the article says that this certain driver unlocks this feature. Maybe this driver can be compared to current desktop drivers and the differences can be replicated.
