Intel Core i7 10700K 8-Core CPU Review

To measure power draw, we hook-up our power meter on another system via USB. Our power meter is capable providing a chart of power the watts currently being consumed by the unit plug into it. We take the average of 15 minutes idle and 15 minutes load to show our power daw. Our load test is SuperPI 12K. A power virus scenario which you will never encounter on regular use. This is a worst-case scenario but is lighter on power than our previous AIDA64 stress test which is an AVX test, which draws more power than normal. The raw data from app is gathered and we get our results.  Temperatures are also captures during this time.


Various configurations will play a factor on how much you are consuming and the same applies to our test. We try to keep our test bench uniform at all times (same memory, graphics card, board if possible, etc). All tests are done with the motherboard or CPU on out-of-box settings as indicated in our Test Setup page with only XMP applied.

CPUs behave on how motherboard vendors handle their boost clocks. In this case, ASUS has opted to disable multi-core enhancement on this board which restrains our CPU to default Intel settings which is a 125W TDP. ASUS has indicated that users can change this  but we’re interest in seeing how processors perform on an out-of-box scenario. AMD has their own implementation but is a little more tame than what Intel permits with their motherboards. The chart below shows our 20 minute stress test with the frequency and temperature readings over time.

As you can see, both CPUs idle in their boost states in the first few seconds but once the workload is initiate a few seconds in, the difference in how they handle all-core load kicks in. Intel will have its Turbo Boost Max kick-in and that will push the CPU but only for a short duration, as it drops to its maximum 125W TDP rating. In this state, The 3900X and 10900K sit just aa few Mhz apart for the rest of the stress test.

This should say CPU Temperature

  1. Monster Hunter World 1080p stable 144fps is still a dream 🙁
    Hopefully the new RTX GPUs at the end of the year will be able to solve this.

  2. Really useful review. Replacing my 9 year old i7 2600k rig shortly and was considering whether to go i9 10900k with 16GB RAM or i7 10700k with 32GB. On the evidence, going i7 again (clocked to 5.1Ghz).

  3. True but as I play MHW IB on both PS4 and PC, I’ve gotten used to just G-syncing on the PC for the smoothness. I doubt Capcom will do anything about it soon but I appreciate the content they’re putting out and I really don’t mind the framerate just as long as we get decent content 🙂

  4. Only 10-15% frame rates vs. a 3700X at almost half the price? Winner AMD. Just wait until the 4000 series comes out this fall. It will beat the 10700K and still cost $150 less and may not require a new motherboard. Winner AMD again!
