Quad-core Desktop processors
"Sandy Bridge" (32 nm)
Based on Sandy Bridge microarchitecture.
Details of Sandy Bridge were leaked to the media in July 2009. The specifications are reported to be as follows:
2.3 GHz[5] to 3.4 GHz clock speed not inclusive of Turbo Boost Technology.
3.0 GHz to 3.8 GHz clock speed with Turbo Boost Technology enabled.
Processing cores will feature Hyper-Threading Technology that is also present in Intel Nehalem-based processors, as well as Intel Pentium 4 processors. 4 cores by default, but processors with 6 and 8 cores will probably be available in Q2 2011.
Approximate 225 mm2 die size by default.
Without SSE: 8 DP GFLOPS/core (2 DP FP/clock), 32 DP GFLOPS per processor.
With AVX: 32 DP GFLOPS/core (8 DP FP/clock), 128 DP GFLOPS/processor.
64KB L1 cache/core (32 KB L1 Data + 32 KB L1 Instruction) (3 clocks).
256KB L2 cache/core, (8 clocks).
8 MB shared L3 cache (25 clocks). This L3 cache will also be shared with the integrated graphic core.
64 bytes cache line width.
Integrated graphics core running at 1 GHz to 1.4 GHz.
Integrated Memory Controller with maximum 25.6 GB/s bandwidth, supports DDR3-1600 dual channel RAM.
256 bit/cycle Ring bus bandwidth. The ring bus connects the cores.
Maximum Thermal Design Power (TDP) of 95W by default.
Release date is expected in Q1 2011.
