Intel Core i7-5820K Review

Introduction

There are plenty of interesting things about the X99 chipset, not least of which is the inclusion of DDR4 support. If you've been looking with envious eyes at the Haswell-E range topping Core i7-5960X but your wallet cannot stand the hit, then like many of us you'll be casting your glance further down the wealth of processors to find one more suited to your pocket.

Enter the Intel Core i7-5820K.

Naturally when you're slashing two thirds off the price some things have got to go, and with the i7-5820K the most noticeable thing is two of the cores. This returns to the territory first marked out by the i7-970 and dealt with well in the initial LGA2011 range of CPUs by being a hex core. Six hyperthreaded cores of goodness, but capable of being run in the latest X99 motherboards with their tasty DDR4 memory.

Does it blur the lines between gaming and enterprise solutions or is it a jack of all trades?

Technical Specifications

As with most CPUs these days the two numbers that count are the amount of cores, six, and the speed at which those cores run. Despite plenty of Intel CPUs getting around the 4GHz mark the i7-5820K is 3.3GHz at default, with a turbo of 3.6GHz. We're sure we can squeeze more out than that, but it's nice to know what there is at stock.

Pretty underwhelming considering it is Intel's first six core CPU in the low end of the "extreme" series of CPUs.

It is pretty much the same story as it was between the 3820K vs 3770K as it is now with the 5820K vs the 4770/90K, except the 5820K has two more physical cores so you would of expected there to be even more of a gap in performance than there is.Quote

Wow that is really surprising, I chose to invest in the 5930K sadly the rig isn't assembled yet. But if I remember correctly other reviewers had the 5820 outperform the 5930, of course it wasn't Tom who did the testing :-P but I don't hope it's the case cause I'd feel like I have wasted a lot of money .Quote

Excellent vid guv, I hope Intel are listening... "sort ya damn speed binning out!", I do see the need for it, but there is a limit surely, this chip seems very underwhelming indeed. They could have chopped a couple of cores off kept the pci lanes and released their first x99 introduction quad core at a friendlier price, I think it would have been better rather than a slightly watered down 5930K..

Kudos on the out takes, made my day. Quote

It's very expensive for what it is really.

I was kind of disappointed with this tbh; I was hoping for a high clocked Quad Core like the 4820k for cheaper than the hex cores, but that 3.3GHz stock clock speed is a bit on the low side. Quote
