Sandy Bridge CPU names and specs revealed

We've just caught our first glimpse of what could be the specs and model numbers of Intel's Sandy Bridge CPU line-up, and it looks as though Intel's decided to start everything off above the 3GHz line this time.

The German gossipers over at Hardware.Infos reckon they've got hold of the details of five Sandy Bridge CPUs, which all feature the 2000-series model number scheme we heard about last month.

According to the site, the dual-core Core i3 2100 sits at the bottom of the pile, featuring a 3.1GHz clock speed, 3MB of Level 3 cache and Hyper-Threading support to enable it to process four threads simultaneously. Just above this sits the Core i3 2120, which is identical except for its 3.3GHz clock speed. Both chips reportedly have a TDP of 65W.

After that you start venturing into the realms of quad-core chips, which once again start at 3.1GHz with the Core i5 2400, and go up to 3.3GHz Core i5 2500. Both chips reportedly feature 6MB of Level 3 cache, and a TDP of 95W but don't support Hyper-Threading.

Finally, at the top of the stack you'll find the quad-core Core i7 2600, which is clocked at 3.4GHz, features 8MB of Level 3 cache and can process eight simultaneous threads via Hyper-Threading. Again, this chip has a TDP of 95W.

According to Hardware.Infos the Core i5 chips apparently feature a new version of Intel's TurboBoost technology, which takes the integrated graphics unit into account as well as the CPU cores. If the site's sources are to be believed, then the combined TDP of the CPU and integrated graphics is capped at 95W with TurboBoost enabled.

This makes sense, given that the Sandy Bridge architecture sees the integration of the GPU portion of the chip into the same die as the CPU. Today's Clarkdale chips with integrated graphics feature the graphics part on a separate die from the CPU, even though they're stuck in the same package.

Previous rumours suggest Intel's Sandy Bridge line-up will be split across two sockets, with the LGA1155 socket handling mainstream chips, and the larger LGA2011 socket accommodating high-end chips. If the specs of the CPUs listed above are genuine, then they're undoubtedly the LGA1155 flavours.

The first LGA1155 CPUs are expected to start turning up at the beginning of 2011, with LGA2011 processors following a few months down the line.
