[Anand] Anandtech Coffee Lake review - Page 10

post #91 of 100
According to Guru3D, availability of these processors happens to be quite low. Price gouging is a thing too. Most of the 8700Ks are going for well over $500 at the moment due to the lower stock, which is funny and makes this seem more like a publicity stunt and exceedingly rushed. Not hating on Intel, I'm all for grabbing a 6-core i5, but if they don't have the stock to push out to consumers, what's the point of this launch?

Honestly? Intel is a MUCH more well known name than AMD. Most people that I know of tend to lean toward Intel out of habit, and you can't really blame them. If Intel releases a new product that's better, people think that all Intel products are magically better. It's amazing how little Intel might have to market to sent a false positive around and generate revenue. But that's my two cents. tongue.gif

From there rare good review I've seen, there isn't much to entice me to switch from 4770K, especially with RAM prices inflated, so I'll wait for Ice Lake.
I 100% agree, I want to see the gains from past generations more so than what they're showing...

Was thinking of upgrading from a 2600 to the 8400. Worth it? I know I'll be paying an extra 40-60$ because of the Z370 ocing ability. But the other mobos are not coming out until next year apparently?

Or.. I was thinking of getting the 8350k and ocing it to 4.7ghz (that swedish review said that's its sweet spot) and take advantage of my Z370...

First world problems right? tongue.gif Honestly though not sure what to do. I do game development stuff and gaming 1080p, 144hz monitor

Coffee Lake + 1070Ti will be under this man's Christmas Tree.

I should be able to get at least 4.5ghz all core on auto, right? Set the multiplier and touch nothing else. I'd at least like to be able to match Kaby's max turbo frequency on auto with the new chip. And then tinker around with other settings to squeeze out a few hundred mhz more.
The individual turbo bins aren't disclosed after Skylake, but the 8700K's max turbo on all cores should be the following:

Core0 = 4.7ghz, Core1 = 4.6ghz, Core2 = 4.5ghz, Core3 = 4.4ghz, Core4 = 4.3ghz, Core 5= 4.3ghz == 26.8ghz if you don't use the multicore enhancement option. The latter will set it to 6 x 4.7 = 28.2ghz

Here's the default turbo clocks for Coffee Lake:



Obviously some motherboards will have "multi-core enhancement" and run all cores at the highest (i.e. 1-core) bin, but that varies by manufacturer and model.

Can the turbo speeds of the i5 8400 be sustained for a longer period of time (gaming) or is this speed only available for short bursts? Of course with sufficient cooling?

Some more questions:
  • Is there a way to make it so it runs at 4.0ghz all the time on those $119 Z370 mobos?
  • In other words, is there a noticeable delay when the cpu goes from 2.8ghz to 4.0ghz all the time?


Ty in advance

196 R15 single core result are pretty much in line with most 7700K.


so that shows 8700K is basically 7700K with 2 cores.

why someone would disable HT on an i7
post #100 of 100
I really hope we will get reviews soon on performance of the locked CPUs compared to the K series. Especially for the 8700...

With that said, I also need to see which motherboard would offer the best options to bring out the potential of a locked CPU
