Intel NDA Desktop Platform Roadmap WW03 2012


Recommended Posts

Over the next few months, Intel will be releasing several server and workstation class processors based on Sandy Bridge. Entry level workstation offerings include E3-1200 v2 and E5-1600, both reliable alternatives to regular desktop offerings. Dual socket processors include the E5-2400 series and the higher performing E5-2600. Finally, we have the quad socket E5-4600 series.

 

We have now seen some initial performance comparisons between Sandy Bridge-EP and Westmere-EP. A document leaked by a Chinese website (PDF file) revealed what sort of performance increase we can expect in Sandy Bridge-EP over Westmere-EP. Various benchmarks were run using an X5690 (with 6 cores/12 threads at 3.46 GHz base clock, 3.6GHz Turbo Clock) and an E5-2690 (8 cores/16 threads at 2.9 GHz), in a dual-socket setup with comparable configuration, except that the X5690 had 40 GB of DDR3-1333 in triple channel configuration and the E5-2680 had 32GB DDR3-1600 in quad channel configuration.

 

Giving the X5690 a baseline score of 1 in each test, we see some interesting results. Both chips have a similar TDP. The X5690 has a core speed 24% higher than E5-2690, but the latter has 33% more cores. Using the synthetic Linpack benchmark to measure matrix multiplication, E5-2690 scored a respectable 2.2. Using OLTP Database (TPC-C Oracle), E5-2690 scores 1.5, while using a middle tier java test (SPECjbb 2005) the score is 1.56. Integer throughput using SPECint_base2006 gives a score of 1.69. Moving to some technical computing tasks, Floating Point Throughput (SPECfp*_rate_base2006) gave a score of 1.82 and Memory Bandwidth (STREAM_MP Triad) scored 1.88. The average performance over these 6 applications is approx 1.78, indicating a projected performance increase of approximately 80% when moving from the high-end Westmere-EP offering to the equivalent Sandy Bridge-EP processor.

 

Comparing the Xeon 5600, E5-2400 and E5-2600 we can see the benefits of the newer systems, and why the E5-2600 series is so powerful.
