Intel's rated TDP doesn't apply to boost clocks. So if you're running a serious load and want your 9900KS to run at 5GHz, you'll need more than 127W worth of cooling capability.
Wait so you are saying that it will run at stock which is 5ghz and even boost a little with a 127W cooler,so what exactly are you arguing against?
That's the difference between warranty and no warranty and while it's only one year with the KS model it's still some warranty.
I seriously doubt that 73W(and I know it doesn't work that way) rest is going to reach high enough for a CPU to throttle it might reach quite high but intel CPUs also only start to throttle at 100°C.
If you're adding heat (power draw) faster than you're removing it, it's going to continue to heat up until either:
no, stock is base clocks, boosting to 5Ghz requires thermal overhead, that requires an overhead over the 127W.
Yes, you're probably right. We already know that Comet Lake will use a new socket.
No, their update cadence on HEDT is a bit slower. However, they have now refreshed the Skylake-X lineup:
My guess is that they'll bump up the turbo clocks by a couple hundred MHz and bump up core counts for most market segments.
That's incorrect. If you have a mobo that keeps it at the PL2 power limit, as many gaming boards do, then you have to dissipate ~190 W, or it will eventually throttle.
The data is in: KS overclocks higher, and at lower power. But, if you only care about hitting all-core 5.0 GHz, then go ahead and buy a K.
If you're not dissipating heat as fast as it's generated by the CPU, then temps rise until the CPU throttles. It's called thermodynamics. Yes, heat sinks will conduct more heat as the temperature delta rises, but not necessarily enough to keep pace with the rate at which it's being generated.
Actually, the TDP even allows for boosting. The way it works is that base clocks are guaranteed to be sustainable with in the TDP envelope, but you might even be able to do a bit of boosting, especially if your workload isn't hitting all cores, isn't using vector instructions, etc.
Maybe no number that Intel publicly advertises, but I think they advise mobo makers & system builders on PL2 thresholds. You guys should take a bit of time and actually read this:
In fact, you can, as long as it's still below PL2 and the elapsed time is less than tau. And, assuming the temperature doesn't breach the throttling threshold within that time.
FWIW, there were a couple air coolers that could handle 2nd gen ThreadRippers that I think dissipate well over 200 W. So, although we're talking smaller area, I wouldn't entirely rule out air cooling.
That wasn't my point, my point is that all intel CPU's, except HEDT, are superseded the following year, so the original posters point that it will be superseded as if this were something special was irrelevant and not unique to this very reasonably priced (compared to what they might have priced it pre Ryzen) special edition.
You know, there's enough confusion around this stuff that it's worth being precise. And it's not safe to assume that someone means something other than what they actually say about it.
I'll side with you, on that point. IMO, a typical user wouldn't count the CPU as truly boosting, unless it sustains the boost clocks for long enough to complete a compute-intensive task of sufficient duration to be bothersome. So, we're talking like a minimum of about 3 seconds, but ideally much longer.
Is that a repudiation of any kind of turbo, or do you just mean sustainable in the way I described?
Okay, but would you agree that Intel's turbo makes sense for "normal" people?
