Since I posted above, two interesting things have released… The Intel 14900t chip, which is *exactly* what I need for my SFF, which is already heat and power constrained. Nvidia rtx 2000 Ada — at $650. Not as big of a delta over my A2000 as the 4000 Ada, but less than half the price. The...

Apologies, Gica, but could you dumb this down a bit for me? Specifically the 45/125 setting? Or maybe you could run a direct comparison between 13700 and 14700 at 75/125? I guess I’m trying to answer two fundamental questions: 1. Is it worth upgrading the 12700k in my SFF pc *at all*, given...

I'm sorry to ask, but I can’t seem to find the Der8auer test you mentioned. Link or additional guidance, perhaps? There were quite a number of tests I read about with the 12th gen in various power limited configurations. But it isn’t clear to me whether I’d get any meaningful additional...

I’ve got a SFF with an i7 12700k and an A2000 12gb. It’s pretty good, honestly. Work stuff, and some surprisingly reasonable gaming performance. But, I can aspire in a year (or two?) to drop in a 14700k and an rtx 4000 ada, once the prices have moderated. I’m new to pcs and components; any...

Any thoughts on how the new chips — but specifically the 14700 — might perform running under-powered at PL1=75 W and PL2=125 W? I have a SFF pc with an i7 12700k, and it is power-limited to stay cool and quiet. At those values, my cpu temps under load test stay below 90 for 30s and thereafter...

That makes logical sense to me. My thought is, if they’re both going to be louder than I’d like, and I’m going to (aggressively?) throttle them both one way or another, I might as well save the money? I hope fan control can help me achieve my desired quiet outcome...

Yeah, I wonder if this enclosure is just a particularly bad fit for the i9? Or maybe the bios is poorly tuned for it? Or maybe the i7 will be just as loud, and switching to the lower processor was dumb. [Shrug] Frustratingly difficult to say. I’m probably much more noise averse — in my home...

So, just to circle back on this… I got the i9k workstation. It was in fact pretty dang loud under any load. There is apparently a **very** steep ramp from no-fan to jet-f’ing-engine. I was able to utilize XTU, to set custom PL1 and PL2 and tau. But honestly, these didn’t make nearly as much...

First, thanks for your time and consideration! I really appreciate your thoughts on this topic. My limited understanding is that 'binning' slots processors into performance buckets. In other words, a chip that can perform at higher frequencies and power (and also hotter) reliably is binned to...

I think I understand the non-linear nature of the performance curve. That's why the i9k, even throttled down to lower power budgets, is faster both at single core AND (somewhat surprisingly) at multi-core workloads. Though there aren't a ton of articles making that comparison, sadly. There...

If the math was that simple, then every one of these chips would bench the same single core performance at the same power level, wouldn't it? According to the article intro, PL1 doesn't matter anymore? Then the closest thing I could find to this scenario is also in the original article. The...

Are you saying that an i5k is faster than an i7k which is faster than an i9k below some low power level threshold (eg 100w)? Especially for multi core loads? That's somewhat counter-intuitive, but not inconceivable, I guess? If that's true, then why does anyone ever buy the high-spec chips...

So to be clear, there is no reason (other than cost) not to get the i9, as long as I’m willing to dial down the PL2 to ameliorate heat+noise, which appears to be possible thanks to XTU. And the upside is marginally better performance — at constant power — than the i7k or i5k.

You wouldn't put too much import on that one anecdotal sample? (And, also, the frame rate in the games test was pretty similar, FWIW.) Faster because i9k has more cores and larger cache? Does the lower base clock (3.2ghz vs 3.6ghz) mean the i9k suffers compared to i7k for single core...

You're saying the rendering results are not what you would expect? Maybe putting the retail i7k in there somehow reset the LP1 to 125? Or maybe the additional i9k cores generated enough extra heat that the clock had to go down to stay within the LP1=90 limit, diminishing overall MT performance...
