Intel Core i7 2600S 

Released January, 2011
  • 2.8 GHz
  • Quad core

If we were amazed by how far the graphics could be pushed in the Intel Core i5 2500T, we were stunned by the graphics overclocking capability of the i7 2600S.

What it really needs as well is the faster HD 3000 graphics core that Intel seemingly deems is only fit for the two K series chips.

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

Many people have heard of the Core i7 2600K by now, the unlocked overclocking demon that was part of the original Sandy Bridge launch, but the Core i7 2600S you may not have heard of.

What People Are Saying Give it to me straight

Socket Type

So instead of the 95W of a standard 2600 part, they have a TDP of 65W, as compared to the 45W of the T series.

Rather you're going to use it because you want the GPU running in a media PC and here Intel have improved the architecture so now H.264 and MPEG-2 encoding and HDMI 1.4/Blu-Ray 3D are supported.
by Tech Radar (Apr, 2011)
Apart from the low power rating, the Intel Core i7 2600S still retains all the familiar features of the 2600 family: four cores, eight threads and 8MB of Smart Cache.

As with the Intel Core i5 2500T, we ran the CPU graphics at the stock speed of the core and again at 1.3GHz.
by Tech Radar (Apr, 2011)
And it also doesn't help that currently the HD 2000/3000 GPU parts don't support DirectX 11 either.

It was pushed to 1.9GHz before it began to produce artifacts in Just Cause 2.
by Tech Radar (Apr, 2011)


The 1.3GHz speed was chosen because it's the fastest we could the Core i3-2100 to run, and it makes a good platform to get like for like benchmark figures before we started to overclock the graphics on the Core i7 2600S.

This time it's the Intel Core i7 2600S.

It's also pretty well known that if a second-gen Core CPU doesn't have a K at the end of the model number, its pretty much game over for any sort of serious overclocking.
by Tech Radar (Apr, 2011)


Unfortunately it still doesn't make Processor Graphics (Intel hates the phrase integrated graphics now) any good for gaming on any of the current crop of high-end games with any degree of high detailing enabled.
by Tech Radar (Apr, 2011)
But lets be honest, you're never going to buy a chip with integrated graphics (sorry Intel) for a hardcore gaming experience.
by Tech Radar (Apr, 2011)
At £200-odd it's a little pricey for a low-power media centre machine, and definitely over-specced for one.
by Tech Radar (Apr, 2011)


So while the overclocking of the graphics is impressive, what about the overclocking potential on the other side of the fence, in the CPU itself?
by Tech Radar (Apr, 2011)
Once again the lack of any form of serious overclocking detracts from what is a very good CPU.
