Is 12600K with a high end DDR4 maybe faster than with DDR5?
I think its non issue in real life use. By the time affordable DDR5 that is fast is mainstream you're a gen further in time.
ADL is a nice first shot at big little, proving the technology can do more than what Intel used to do. It opens new ways to direct power where its needed most, adds flexibility. But its also an early adopter gen. Both for new DDR and for the arch. It won't gain its best numbers in this gen.
This gets stupid.
If your #1 use is gaming, let us assume for example you game 8 hours a day 365 days a year. And you pick something that uses an extra 20W of power.
That's 0.16 KWH of power per day, or 58KWH per year.
The average cost of electricity in the USA is currently 12.55c / KWH.
That's $7.25c per year for the average US household. If you game 8 hours constantly 365 days a year. I game way too much I think but I believe it's more like 2 hours a day not 8.
Just stupid waste of time to discuss it.
The efficiency AND the gaming performance are a strange beast. I don't think personally, anyone is even half serious about the
cost of electricity wrt a CPU TDP/load wattage. What I rather think, and I say this because that is also my personal experience over all these years, is that
temperature is a performance limiter, and it rapidly adds noise + expenses on extra cooling to your build.
The fact is, ANY application, at ANY given time, can present a type of load to a CPU that puts it in maximum gear. With the strong improvements to multi threading and scheduling, this is only more likely to happen as time progresses. We see it, too. Its historical fact, as well. I know I ran a 3570K a few years ago and it would readily use more power than it did when I bought it, even under the same OC. Why? Simple, applications utilize cpu cycles better, and they need more of it, as GPUs get faster.
So yes, I completely, totally understand people are ready and willing to mix up the worst case energy metrics with their personal take on how the CPU could possibly run their games or applications. Its what I would do. You just WANT to be able to run the CPU in the red and not smell burnt electronics.
And power, is temperature. We know these CPUs can push 241W, and we know what kind of heat they produce in that case. Also, the argument applies universally. AMD's Ryzen gets hot too, but its not quite as toasty nor has such a horrible inefficiency at the top end.
When AMD produced hotter GPUs, I was staying away too. Now that Nvidia produces Samsung 8nm Ampere GPUs, I'm staying away too, and if any GPU would become cost effective in some way, I'd prefer 7nm TSMC any day of the week, yes I'd even sacrifice RTX for it without blinking twice. The fact still remains that on hard efficiency, Intel still loses node-wise to AMD/TSMC 7nm, which is a node already in refinement too. And these things do count. The silicon is the key differentiator, especially when competing architectures share the majority of perks.
Your argument would also apply to the 10400f. Why the heck would you buy a 5600x when the 10400f costs half and has similar performance with a 500$ GPU (what gpu is that today, a 3060?). The answer is simple. Future proofing. While the 10400f would perform similarly with a 3060, 1 or 2 years down the road you might upgrade that 3060 and your CPU is now the bottleneck, meaning it needs an upgrade. It's the same thing now with the 5600x. It will be cheaper today but youll pay more down the line cause youll need an upgrade sooner.
Unlikely. GPUs may get faster, but demands in games on that GPU also increase, while the CPU demands tend to remain stagnant until the consoles push up the mainstream again.
I have yet to see a single core limitation for gaming on my 8700K. And that's with an efficiency oriented OC, I run 4.6 Ghz... Sure I can fire up CS GO and maybe I'll have a few dozen more frames above 600... but who cares? ALL CPUs even from yesteryear are more than capable for gaming, they have the core count and the IPC, and the current console crop won't be changing soon either.
