Some sketchy details of the Sandy Bridge Core i7 processors have started appearing. The core i7 of the Sandy Bridge processor include Core i7-2600K core i7-2600S and core i7-2600 processors.
The Core i7-2600K part is for the overclockers and has the over clocking enabled. The frequencies of the Sandy Bridge Core i7-2600K core i7-2600 processors are 3.4 GHz parts while the core i7-2600S is a 2.8 GHz part.
The Sandy Bridge processors are not going to significantly alter the speed of the processors. You are going to see just a 10% improvement in the performance of the Sandy Bridge processor over the similarly clocked Arrandale and Clarkdale processors.
But if you are a gamers, the things change. The Sandy Bridge processors promise two fold increase in the performance of the gaming graphics. This has been verified by some of the benchmark results available.
There are some architectural improvements as well. The Cache in the core i7 Sandy Bridge processors is shared by the GPU. This leads to significant performance improvement.
The GPU, CPU as well as the Integrated memory controller are built with 32 nm technology. This is unlike the earlier Arrandale and Clarkdale processors where the GPU and the memory controller were built with 45nm technology even when the CPU was built with 32 nm technology.
Just wait for the CES 2010 and we should have more news about the core i7 Sandy Bridge processor. It will be interesting to see how it performs against the AMD Fusion chips.
