SiSoftware Sandra Lite 2010c

SiSoftware, founded in 1995, is one of the leading providers of computer analysis, diagnostic and benchmarking software. The flagship product, known as "SANDRA", was launched in 1997 and has become one of the most widely used products in its field. SANDRA is used by almost 500 world-wide IT publications, magazines, review sites to analyse the performance of today's computers. Over 5,000 on-line reviews of computer hardware that use SANDRA are cataloged on the company's website alone.

SiSoft's Sandra is a good way to paint a picture of overall system performance. It is important to note that because Sandra is a suite of synthetic tests, the numbers don't always correlate directly to "real world" performance in "real world" applications. That being said, it is a good stress test, and it does allow us some insight into peak theoretical performance.

It should be noted that, where applicable, I told Sandra to specifically address Processor 1 (P1), Core 0 (C0) and Thread 0 (T0).

We'll start with the CPU tests...

SiSoft Sandra CPU Arithmetic - Westmere

SiSoft Sandra CPU Multi-media - Westmere

SiSoft Sandra Multi-core Efficiency

Remembering that Westmere EP brings 50% more cores and 50% more cache to the party, these numbers appear to fall right where we would expect them to. So, let's see how the new and improved memory controller stack-up.

SiSoft Sandra Memory Bandwidth - Westmere

SiSoft Sandra Memory Speed - Westmere

SiSoft Sandra Cache and Memory Latency - Westmere

In the memory bandwidth test the new X5680 Xeons lag behind a bit. This might be a software issue (Sandra not understanding how to address the new memory controller) because the other numbers appear to be right where I would expect, slightly faster than the W5590 Xeons.
