Reviews Word on the street for the Intel Core i7 2600K

8.0
read review
In Futuremark's 3DMark Vantage, its score of 11,583 is okay and its 2,173 rating is solidly unexceptional—at the Entry (1,024-by-768) and Performance (1,280-by-1,024) presets respectively.
9.0
read review
Intel's Sandy Bridge brings much higher clocks, but it's also interesting to note how performance compares on a clock-for-clock basis.
9.7
read review
It delivers incredible performance for its price, and in scenarios where all 8 threads can be fully utilized it will definitely prove its worth.

Overall
9.1 Out of 10

What People Are Saying Give it to me straight

Socket Type

As fine as the Core i7-2600K was at photo and video processing, it had more trouble getting over the hump in terms of 3D gaming.
by PCMag (Jan, 2011)
I was initially content with a 4.5ghz OC using a vcore of 1.296v, but curiosity got the best of me and I later found that I needed 1.356v for 4.6 stable and 1.376v for 4.7 stable.
by Velathawen (Nov, 2011)
With a good motherboard, its incredibly easy to overclock, and the voltage needed to hit 5ghz is fairly low (im at 4.96ghz @ 1.395v).
by doomlord52 (Nov, 2011)

Socket

The Core i7-2600K also smoked all comers in our Photoshop CS5 test, blasting through all 12 filters in 2 minutes 57 seconds.
by PCMag (Jan, 2011)
The average frame rates we saw in our 1,280-by-720 tests weren't much better with the Heaven Benchmark (13 frames per second), Lost Planet 2 (22.3 fps), or S.T.A.L.K.E.R.: Call of Pripyat (22.2 fps).
by PCMag (Jan, 2011)
The same was true of our 1GB TrueCrypt 7.0 encryption test, with the Core i7-2600K taking the prize with a best-in-class speed of 195 MBps.
by PCMag (Jan, 2011)

Multicore

Even six-core Gulftown Core i7s look marginal.
by Tech Radar (Jan, 2011)
For launch, Intel has cooked up dual- and quad-core derivatives.
by Tech Radar (Jan, 2011)
It's yours for approximately £160 unboxed and effectively replaces both the old dual-core Core i5-655K and quad-core Core i5-760.
by Tech Radar (Jan, 2011)

Applications

Intel takes a giant step forward with the Core i7-2600K, one of its inaugural Sandy Bridge CPUs, in terms of both value and media processing.
by PCMag (Jan, 2011)
It's not legendary in the 3D department, but its media processing is superb, and in many ways it surpasses similarly priced predecessors from both Intel and AMD.
by PCMag (Jan, 2011)
What Intel had told us about the Sandy Bridge chips' prowess plowing through media-centric chores was even more fully proven.
by PCMag (Jan, 2011)

Performance

This is not to say that game lovers will want to chuck their discrete cards, especially if they're of the high-end persuasion.
by PCMag (Jan, 2011)
The performance is amazing as well.
by doomlord52 (Nov, 2011)
Intel says it delivers at least twice the performance compared with previous architectures encoding video in software, but a little Intel birdie tells us you can often expect much more than that.
