Intel's Sandy Bridge-E Extreme Chip to Boost Performance

From X-bit Labs: Intel Corp.'s next-generation Core i7 "Sandy Bridge-E" microprocessors for performance enthusiasts will deliver from 12% to 65% higher performance compared to current extreme chips, according to estimates by the manufacturer. Thanks to Sandy Bridge micro-architecture and other improvements, the new chips will offer tangible performance boosts compared to existing offerings from Intel.

According to a document with Intel's performance estimates of the Core i7-3960X processor (six cores, 3.30GHz, 15MB cache) seen by X-bit labs, the forthcoming chip for the LGA2011 platform is clearly faster than its predecessor Core i7-990X (six cores, 3.46GHz, 12MB cache) across a range of benchmarks despite of lower clock-speed amid the same amount of cores due to advantages of the Sandy Bridge micro-architecture over Nehalem/Westmere micro-architecture, quad-channel memory controller and other innovations.

The rough estimates of performance advantage of the Sandy Bridge E-series Core i7-3960X compared to the model Core i7-990X are the following:

+13% in Cinebench 1.5
+12% in POV-Ray 3.7
+36% in 3DMark 11 Physics Test
+15% in ProShow Gold 4.5
+34% in SPECint_rate base 2006
+65% in SPECfp_rate base 2006
+111% in Sandra 2011B/Multi-Media FP sub-test
+92% in Sandra 2011B/Memory Bandwidth FP sub-test
