Not sure it will be much of a hot topic, after all the change from clocks as advertised to boosts to whatever it feels like went over without much of a stir for GPUs.
Where does Intel have the information about each max turbo frequency with however many cores active? All I can see on their data sheet is 1 core max turbo frequency, then base clock. Unless there's another data sheet that I've missed with that info.
Their core boost would be different for different core loads. One core boosts to the max, two boost to one multi lower and so on.
Yea I get that, I was wondering if said boosts were listed somewhere like they do with single core turbo but in some other location.
In the blog post it says Intel's plans to no longer state the multi-core boost frequencies of its new processors so I'm guessing, and based on other things I've read, that they're not going to list more than the base and single core boost clock speeds, i.e the highest and lowest numbers.
Intel announced a while back - last year? year before? I forget - that they wouldn't be listing detailed turbo speeds, just single base and boost clocks.
My worry with CPU's that can boost very high on 1 core is that application developers will get lazy and start exploiting that, rather than continue to advance multi-threaded/parallel performance...
Correct. It's been available for some CPUs on Intel's website and obviously in press pack info around launches but that's all stopping apparently. You can still see the boost frequencies for different loads for some CPUs at places such as CPU-World. The trouble is, the drop off as you load more cores is not always linear, ie one multiplier notch down per extra core used, so unless us reviewers bother to identify those frequencies, there will soon be no way of knowing
So how is the article able to say up to 4.2GHz for 4 core turbo on the 8600k etc if the drop of is not always linear? Could it not in theory, for 4 cores, boost to the 4.3GHz of the single core turbo or 4.1GHz of the number you've suggested is the max for 5/6 core turbo? Or have Intel said each drop down, i.e. 1 core turbo -> 4 core turbo -> 5/6 core turbo, will be at least one multiplier different?
If Intel are so vague with their turbo speeds, should the article not be equally vague and say something like max 1 core turbo for the 8600k is 4.3GHz, base clock is 3.6GHz, all other turbos are somewhere inbetween?
I like frequency boosting, it's a great idea to get more performance out of a processor when able to, however I dislike the more fluid nature of the performance that you'll be getting. I remember thinking the same thing when boosts appeared in GPUs and thinking that they should be benched at their base clock as anything above that was a bonus and not guarenteed. I mean in theory you could be really lucky and get an absolute turd of a cpu/gpu only ever hitting it's base clock correct?
