Measuring Cache and Memory Latency (access patterns, paging and TLBs)

Why is it important to measure it? The latency of the main memory directly influences the efficiency of the CPU, thus its performance: reducing wait time can be more important than increasing execution speed. Unfortunately, memory has huge latency (today, by a factor of 100 or more): A CPU waiting for 100 clocks for data would run at 1/100 efficiency, i.e. 1% of theoretical performance!

SP1 for Sandra 2012: AVX2, IPC, hardware and software optimisations

florin.dranca.take.out@sisoftware.co.uk (Florin Dranca) — Mon, 12 Dec 2011 00:00:00 GMT

After releasing the 2012 version we thought is best to release the SP1 just in time for Christmas and the New Year. It contains new functionality as requested by some of you as well as fixes and further support.

Sandra 2012: Device Performance Certification, General Processing (GP) for GPU/APU, .Net/METRO for Windows 8

florin.dranca.take.out@sisoftware.co.uk (Florin Dranca) — Mon, 7 Nov 2011 00:00:00 GMT

In preparation for Windows 8 and its brand-new METRO API running on .Net (as used on Windows Phone 7.x), we have updated our .Net benchmarks that can measure .Net CLR performance. A new METRO style interface is also included for Windows 8 users. The GPGPU benchmarks have been upgraded to General Processing (GP) benchmarks, able to fully test the new APU (CPU+GPU) processors.

Using statistical analysis tools against the 1 million+ benchmark results submitted to the Official SiSoftware Ranker, you can now certify whether your tested device operates at peak performance. Based on the quality and variability of the results you can determine whether there are issues with the device that need to be addressed.

Mobile GPAPU Performance: AMD "Llano" APU (CPU+GPU)

florin.dranca.take.out@sisoftware.co.uk (Florin Dranca) — Wed, 11 Aug 2011 00:00:00 GMT

What is it? "Llano" is a new CPU architecture that includes a built-in GPU from AMD from the "Fusion" family - alias an "APU". "Llano" mobile targets laptops i.e. Intel's Mobile Core i3M-i5M territory. What difference does the APU make? more...
