Intel are preparing to raise the performance bar with the coming X79 platform and Sandy Bridge-E CPUs.
It has been revealed that the flagship CPU will be the Core i7 3960X which is 6 cores and 12 threads via Hyper Threading Technology, a full fat 15MB L3 cache and clock speeds coming in at 3.3GHz and a Turbo Boost upto 3.9GHz. I am unsure /lost in translation if the Extreme edition is Bclk multi unlocked or even if it will feature the 'unlimited turbo within TDP' feature that was rumoured in early on... (Or did i make that up in my head?)

The i7 3960X is likely to require the sale of vital organs.

Next up is the i7 3930K, another hex with 12 threads featuring unlocked multiplier for those overclockers out there. Coming in with a base speed of 3.2GHz and Turbo Boost to 3.8Ghz and 12MB of L3 cache.

The cheapest 2011 chip available will the the i7 9820, a quad core with 8 threads and 10MB L3 cache and speeds of 3.6GHz and Turbo Boost to 3.9GHz. This model however has a locked multiplier.

All Sandy Bridge-E CPUs will feature quad channel DDR3 ram and support PCI-E 3.0 as well as other similar features.

Update>> It would appear that each model has a TDP of upto 130w.
