Sisoft Sandra: Data Encryption

SiSoftware Sandra (System Analyser, Diagnostic and Reporting Assistant) is a diagnostic tool that can provide detailed information about your computer hardware and software configuration. A year ago, SiSoftware Sandra 2010 released offering full support to Windows 7, to 18 months after the launch of Windows 7, we have witnessed a real coronation of the PC to the media hub. A few months ago was released a benchmark dedicated to the Blu-Ray, now the authors have focused on delivering a new benchmark: the Media Transcoding based on Windows 7 Media Foundation. To all was given a new benchmark (GPGPU Cryptography) which allows a direct comparison between the performance recorded by the CPU (using the set of encryption available) and those of GPGPU.

Very interesting test, which highlights the new architectures that have hardware encoding for data encryption, using SHA and AES 256 instructions. You can see that in general the old architecture lacking of hardware encryption are far behind compared to other of new generation. But we see how AMD A8-3850 and Intel i3-2120 even if of the new architecture they are deprived of them. Instead observing Bulldozer we see clearly how hardware encoding is present, but the result is just below the Intel i7-2600K both with HT enabled and with HT disabled.

The situation with the CPU operating frequency at 4 GHz does not change from before. The CPU is located behind the Intel i5-2500K.
