Average Bench: 85.2% (23rd of 967)

Based on 26,187 user benchmarks.  Devices: BFEBFBFF000306F2, , 0F8BFBFF000306F2, 1FABFBFF000306F2 Model: Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz

The Intel Core i7-5820K is the cheapest of three (5820K,5930K,5960X) new Haswell-E prosumer/enthusiast processors. The 5820K sports six physical cores and twelve threads which allow for enormous processing throughput. Unfortunately Intel have somewhat handicapped the 5820K by setting its base clock at just 3.3 GHz, 0.7GHz lower than the class leading 4790K. Comparing the 4790K and 5820K shows that the cheaper i7-4790K is significantly faster at both single and dual threaded workloads. The additional two cores found in the 5820K are not relevant to general computing and as such the 5820K probably makes a better server rather than consumer proposition. The Haswell-E X99 architecture also requires DDR4 RAM which is currently far more expensive than DDR3. Overall the 5820K is a very expensive option and probably best avoided by the vast majority of consumers.  [Sep '14 CPUPro]

amazing processor. just upgraded from an amd fx 8350. its paired with an msi x99a gaming pro carbon motherboard, 16gb geil evo x ram, and an amd fury x. ive overclocked the cpu to 4.0ghz (havent felt the need to go faster), with a nzxt kraken x41 and my temps at idle are around 38*C and it never goes above 55*C when gaming. when im just dicking around in windows or on the web, i havent noticed a difference from my fx8350, but gaming on cpu intensive games, this chip blows the former away. (gpu intensive games i couldnt tell a difference, thank you fury x btw). i was trying to hold out until amd released zen, but i pulled the trigger and bought an i7. if i could do it over again, i would.—Nov '16


Excellent

Great perfom, best temps and cooling without watercooling. The real Ram-Timings are pos. higher as the tech spec mean. Work with low cpu power on all cores with 4.1 Ghz!


Poor

Compared to the 6800k, much better overclocked now Haswell-e is mature

Currently cheaper than skylake, more cores and better heat spreader for over clocking.

Absolutely Nice CPU! In Use with Asrock X99 extreme6/ac, and 16GB HyperX Fury DDRs 2444mhz Ram and an MSI GTX750 2GB DDR5!

An excellent overclocker for its price, the additional two cores will be definitely beneficial for any video rendering or load heavy tasks.

Great cpu . Good value,exellent speed and overclocking . (My oc is 4.9 Ghz on costum water cooling)


Very good

4 months ago.

This processor has server med very well and handles anything I throw it at with no issues. Easily clocks from 3.3 to 3.8 without any issues. I am watercooled however with corsair H110i.
