Intel Core i7-875K 2.93GHz Unlocked Quad-Core Processor Review

SiSoftware Sandra 2010c

The Sisoft Sandra 2010c benchmark utility just came out a few weeks
ago and we have started to include it in our benchmarking. Sandra 2010 now 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!

Results:
Sandra 2010c showed that the
Intel Core i7 875K having nearly 20GB/s of memory bandwidth, which is great for a dual-channel platform running 1600MHz with CL9 timings.

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

Results:
Once again the Intel Core i7-875K processor does very well.

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 that we recently benchmarked. 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 Intel Core i7 875K
Processor does not have AES-NI, so the Cryptographic Bandwidth isn’t anything special, but it doesn’t bad either!
