Today, Intel released their Core i7-3000 series of processors, codenamed “Sandy Bridge-E.” Two models were launched, the Core i7-3960X Extreme Edition and the Core i7-3930K, with a third model (Core i7-3820) scheduled for 2012.
These new processors, along with the new Intel X79 chipset, constitute an entirely new platform, dubbed the LGA2011 platform. Sandy Bridge-E chips have the same instruction set as the Sandy Bridge chips. The difference between them lies in the memory controller. Sandy Bridge-E CPUs feature the new quad-channel memory architecture supporting DDR3 memories up to 1,600 MHz officially, while Sandy Bridge CPUs feature triple-channel memory architecture and support DDR3 memory up to 1,066 MHz.
The new LGA2011 CPUs have a total of 40 PCI Express lanes for video cards. This allows the following video card configurations:
In the table below you can see the models launched and their main specs, including prices.
Model | CPU Cores | Clock | Turbo Clock | HT | L3 Cache | Socket | Technology | MSRP (U.S.) |
Core i7-3960X | 6 | 3.3 GHz | Up to 3.9 GHz | Yes | 15 MB | 2011 | 32 nm | USD 990 |
Core i7-3930K | 6 | 3.2 GHz | Up to 3.8 GHz | Yes | 12 MB | 2011 | 32 nm | USD 555 |
Core i7-3820 | 4 | 3.6 GHz | Up to 3.9 GHz | Yes | 10 MB | 2011 | 32 nm | - |
