Reviews Word on the street for the Intel Core i7 2700K

But all of its other characteristics are identical: 8MB of cache, four cores and eight threads (thanks to Intel’s Hyper-Threading technology), integrated Intel HD Graphics 3000, and the full line of shiny Sandy Bridge features, ranging from Turbo Boost 2.0 (which temporarily increases processing speed when the appropriate head room is available), Quick Sync Video (for faster rendering and conversion of video files), and so on.

We've transitioned through 90nm, 65nm, 45nm and 32nm silicon, with 22nm CPUs just around the corner.

it is an awesome processor for folding since it runs cool and is so stable at such high overclocks.

What People Are Saying Give it to me straight

Socket Type

Benchmark Results:The AMD FX-8150 was able to out perform the Intel Core i7-2700K in this gaming benchmark, but we did see a 1-2 FPS improvement over the Core i7-2600K.
by Legit Reviews (Oct, 2011)
When it comes to pricing the Intel Core i7-2700K carries a recommended channel price of $332.
by Legit Reviews (Oct, 2011)
Benchmark Results: PCMark 7 showed that the AMD FX-8150 was able to score 4351 points and the Intel Core i7-2700k scored 4333.
by Legit Reviews (Oct, 2011)


Benchmark Results:The Intel Core i7-2700k uses the same amount of power as the Intel Core i7-2600K at an idle state, but was found to use 4-7 Watts more when run at various load states.
by Legit Reviews (Oct, 2011)
Benchmark Results: S.T.A.L.K.E.R.: Call of Pripyat doesn't exactly scale well across multiple cores and we only could see a difference with the Intel Core i7-2700K when gaming at lower resolutions.
by Legit Reviews (Oct, 2011)
During regular use with all four cores under load the Intel Core i7 2700K can jump up to the rated clock frequency of 3.50GHz or 3.60GHz if Turbo mode is enabled.
by Legit Reviews (Oct, 2011)


Yes, it's a very nice little quad-core chip.
by Tech Radar (Dec, 2011)
Suffice to say we view its hidden cores as evidence Intel has taken its foot off the gas.
by Tech Radar (Dec, 2011)
When Intel released its line of second-generation Core processors a year ago (under the “Sandy Bridge” code name), it offered consumers new opportunities in various areas of CPU performance, regardless of how much you wanted to spend.
by PCMag (Apr, 2012)


Benchmark Results: The x264 HD benchmark is very CPU intensive and it showed the Intel Core i7-2700K beating the AMD FX-8150 Bulldozer on both the first and second passes.
by Legit Reviews (Oct, 2011)
For better integrated graphics at this point, AMD APUs are the preferred way to go—but you’ll sacrifice raw performance as a result.
by PCMag (Apr, 2012)
The Intel Core i7-2700K was able to tie or beat the AMD FX-8150 Bulldozer processor in all of those benchmarks.
by Legit Reviews (Oct, 2011)


Not a bad price considering the performance you get and remember that these are fully unlocked processors and they love to be overclocked.
by Legit Reviews (Oct, 2011)
I have been able to overclock this processor to 5.3ghz @ 1.45v stable with temperatures under 50 degrees under load under water.
by DizZz (Jan, 2013)
This is a fully unlocked processor, so you can manually raise or lower the multiplier if you'd like to overclock the processor.

Wow, this processor handles pretty well against the 3rd and 4th gen variants.
