The Intel 12th Gen Core i9-12900K Review: Hybrid Performance Brings Hybrid Complexity
by Dr. Ian Cutress & Andrei Frumusanu on November 4, 2021 9:00 AM ESTCPU Benchmark Performance: Intel vs AMD
Here are the graphs you've probably be wanting to see. Here we've listed Intel's last few flagships, along with AMD's Zen 3 offerings. In no particular order, here is the CPU performance.
It's hard to miss a lot of blue bars at the top of these charts. ST performance usually reigns supreme, and it shines though. Intel does take a few other wins here in multi-threaded as well, and users will point to CineBench. CB loves lightweight threads and cores, and with the combined improvements in the out-of-order window in both cores as well as memory access improvements into the L2 caches.

This. People often get halfway through the analogy and then give up when they think it's made their argument for them.Dribble - Sunday, November 7, 2021 - link
The having lots of potential power and high power consuption is exactly what mobile phones and laptop cpu's do. That Intel do that in desktops too is not surprising.Spunjji - Friday, November 5, 2021 - link
99% of users don't need a 12900K. Presumably the people who do are likely to use it for these tasks where it will actually show a performance improvement over a cheaper CPU (accepting that some people overspend for e-peen reasons and will buy one for gaming where a 12600K would do just as well).lmcd - Friday, November 5, 2021 - link
99.9999999999% of users don't need a 12900K peak performance constantly, even if they will use the peak performance sometimes, including times when it definitely counts.I won't lie and say I have the best of the best, but Zen 2 vs Zen 1 cut down my build times noticeably. That helps keep me in flow, even if it's only saving me a few minutes per day. For people like me with ADHD or other attention-related issues, this can be a massive boon.

Does efficiency really matter for top end desktop SKUs? Intel/AMD tend to clock these near their voltage walls, WAY outside the "sweet spot" of a given architecture, and you can get a boatload of efficiency back just dropping boost clocks by 10% yourself.Now, if the laptop SKUs end up being power hungry, thats a different story.

Same core design, same process. So.... I'm sure Intel will lower clocks for mobile and servers to get power usage down, but once they lower the clocks, how will the performance compare?meacupla - Thursday, November 4, 2021 - link
For now, efficiency doesn't matter for desktops, but in a few years time, we are very likely to see laws passed that will mandate high efficiency in high end desktops.There are already some legislation in the works that calls for exactly this, but have not been passed yet.

And how, pray tell, are they going to legislate that? Max power usage for a CPU? We've already seen how california tried it, and predictably they made a mess of it.INB4 intel just refuses to sell anything but a celeront o californians and mysteriously tech resellers in arizona get a bunch of cali orders. Hmmmm.....

don't ask me, IDK how law makers will do it. Just be aware that there are some really dumb laws that are already in existence, and the world is going to be entering an age of power shortages, along with carbon neutral incentives.Considering how things are going currently, I think it'll just be a 100% tax on desktop CPUs that can't hit some efficiency metric that Apple has designed.

Doubtful given how poorly the existing law works. All they do is measure computer idle wattage. The lawmakers aren't techies. And they're busy handling the blowback from carbon neutrality bills that the pubic believes are related to power shortages and cost spikes.
