Earlier quoted context omitted.

I still want my computer to remain responsive even when I'm rendering in the background.

+1. it's great that it compiles code faster, but i would also like when i'm writing code and hit enter, a newline is added and all lines under it goes down by 1 without any "lag". That's why i decided to go with a 5950x + 3090 rtx + gamer ram for my current "workstation" instead of a 5995wx + rtx 6000 + ecc ram for my current machine. even tho its not workstation rated, it seemed like the better way to go for quality…

Having run a 3945WX machine side by side with same era intel and AMD desktops the Threadripper Pro was the more “responsive” machine, but it was minor enough you would have had to have them side by side to really notice.

Once there were a lot of programs in flight it started making a larger and larger difference. Now half my family and friends have TR Pro systems bought refurbished (they watched eBay) because they loved mine so much.

IMHO, increasingly inefficient software notwithstanding, CPU performance has been well beyond acceptable since a long time ago. Thus, the real question is how buggy these new CPUs will be. https://news.ycombinator.com/item?id=37812556

> CPU performance has been well beyond acceptable

For simulation applications there is no such concept as "acceptable", the utility of a CPU scales linearly with how fast it can do the calculations.

Has anyone done a perf / watt scatterplot of the current AMD and Apple offerings? I'd guess this wins in absolute performance (due to the TDP), but I've heard AMD is pretty competitive on energy efficiency too these days. I'm typing this on an M2, which is simultaneously cooler and faster than my old Intel laptop. Wondering if it's time to upgrade my decade-old Intel Linux desktop to an AMD yet.

I have an older threadripper - a 3970x. It's the most power hungry device in my house after my electric oven. In raw numbers it's hard to beat. But it is _not_ efficient

AI systems are the new hungry monster. They're still pretty slow on expensive hardware and not everything is GPU based for reasons I don't fully understand. (I've got GTX/4090s and TR/3990x with 256GB of pretty fast ram and an NVME array for storage and have done a bunch of things related to AI/ML where I walk away for a few hours or even a day - both CPU and GPU get pretty taxed.)

CPUbenchmark is giving the new chip about a 100% improvement over the 3990x which is fairly tempting even at the 6-10k price tag I've seen floating around.

That is now a two generation old CPU at this point - I don't think we started seeing AMD get competitive on power efficiency until Zen 3.

I have the same chip and it's amazing to see it idle at 75W after growing up on Intel chips that use like 5W at idle.

Of note is that Zen 2 (the 3970x's microarchitecture) is 7nm. The new Threadrippers are on a 5nm process. I would expect slightly lower power consumption, but note that the 7000 series of Threadrippers quote a TDP of 350W while the 3000 series quote 280W. So I'm guessing they're using the efficiency for more speed instead of more power savings.

To me, it's fine. I'd always prefer paying more for electricity than to wait longer for something to complete. (But I do respect the desktop chips that can blink my cursor with an efficiency core that uses a few tens of milliwatts.)
