The Sisoft Sandra 2011 SP3 benchmark utility just came out a few weeks ago and we have started to include it in our benchmarking. Sandra 2011 comes with support for Virtualisation (Virtual PC/Server, Hyper-V, VMware) and GPGPU (OpenCL, DirectX 11 DirectCompute), but today we will be using the program to look at memory and CPU performance!

Sandra 2011 SP3 Memory Benchmark Scores

Results: All of test systems used the identical G.Skill Ripjaws X Series 8GB (2 x 4GB) memory kit that ran at 1866MHz with 9-10-9-28 1T timings. While the memory kit and settings were identical the memory performance was very different as you can see from the chart above. The Intel Pentium Processor G620 was found to have roughly 22 GB/s of memory bandwidth with 1866MHz CL9 memory. This is slightly slower than the other Intel 'Sandy Bridge' processors that we have tested, but remember the G620 is at least 500MHz slower than the rest and is the only dual-core processors tested that doesn't support Intel Hyper-Threading Technology.

The Sandra Processor Multi-Media benchmark has been a long time favorite of ours to look at floating point performance on processors.

Sandra 2011 SP3 Benchmark Scores

Results: The Intel Pentium G620 had a respectable score in the Int x16 iSSE4.1 test, but performance really fell apart in the iSSE2 tests and the Intel Pentium G620 was nearly twice as slow as the AMD A-Series of APUs.

Cryptography has become an important part of our digital life: it allows us to conduct safe transactions online, certify programs and services, keep our data secure and much more. Sandra 2010c has a dedicated benchmark built-in that measures cryptographic performance, which is important on the new Intel 32nm processors like the Core i7 980X. It includes features like AES-NI! Intel AES-NI is a new set of Single Instruction Multiple Data (SIMD) instructions that are going to be introduced in the next generation of Intel processors, as of 2009. These instructions enable fast and secure data encryption and decryption, using the Advanced Encryption Standard (AES), defined by FIPS Publication number 197.  The architecture introduces six instructions that offer full hardware support for AES. Four of them support high performance data encryption and decryption, and the other two instructions support the AES key expansion procedure. Let's take a look at how this feature impacts Cryptography performance.

Results: The only processor tested that has AES-NI instructions that we benchmarked was the Intel Core i7-2600K and it dominated the test. The Intel Pentium G620 has the least number of thread and was the lowest clocked processor of the group, so we figured it would end up at the end of the pack here.
