Thanks a lot for the answer! That's a good point about the VRM, but I thought it won't be as big a deal because I wanted to throttle it anyway. Still an important consideration. Half the Z690 boards I looked at don't look very trustworthy in that regard.
Things would probably be a lot simpler...
12900k is faster everywhere, though (which is expected - it has two more big cores), so I guess it comes down to which seller is more reputable. On the other hand, the 13 series seems to be better tuned (or just better stepping) in terms of power efficiency - still terrible, but better.
But...
I'm on a tight budget, DDR4 support is a plus (as it's cheap and I already have plenty of it, while DDR5 is expensive and I think investing into it right now is too early). Second-hand CPU availability is a factor as well, there's 12600kf for $150 (or 13600kf / 12900k for $250). I could find...
Hi, pardon my noobish question, I haven't had an Intel system since Sandy Bridge. The question is this (as I prepare to build a new PC and struggle choosing between Zen 4 and Adler/Raptor Lake): I'm not interested in OC, but I am interested in downvolting / power limiting. With a "K" (unlocked)...
I was considering the 13xxx series a complete joke until I was told about ICC limiting and shown this example. From a couple reviews where 7950X / 7950X3D were power-limited (Techpowerup has a good one here), this seems to be on-par:
I indeed meant Raptor lake, thank you for pointing out my typo, hopefully now I'll remember which is which. So is IccMax limiting available to non-K parts?
Do the non-K 13xxx CPUs allow IccMax control? I've just learned that Icc power-limiting works much better for Rocket Lake than the actual PL, and then a tuned Rocket Lake is the same on power efficiency as Zen 3/4 and not 1.5x worse. This totally changes how I perceive these CPUs and I might try...
I tried running two parallel benchmark instances, and got exactly twice lower score in each. And it makes sense for all I know, since memory is a lot slower than CPU, so even a single core should have no problem saturating it as long as it doesn't spend too much time processing the values it's...
Thanks for the info, so ranks act somewhat like channels, if the module has two ranks?
But my modules are both single rank and they have identical number of RAM chips.
I was curious about how easy or how difficult it is to measure RAM speed (and to saturate RAM bus), so I wrote my own RAM benchmark and spent a couple evenings optimizing it.
First, about my PC. It's a Lenovo Thinkcentre M920q with Core i5-8500T and 2x16 GB of DDR4-2666 RAM that decided to work...
