L’utilitaire SiSoft Sandra 2011 continue son petit bonhomme de chemin et nous arrive aujourd’hui en version SP5 17.80. Il s’agit principalement d’une mise à jour de routine qui intègre plusieurs changements et améliorations au niveau de l’API logiciel et matériel du programme.
Voilà d’ailleurs la liste officielle des changements apportés par Sandra 2011 SP5 17.80 telle qu’elle nous a été communiquée par l’éditeur SiSoftware.
– Clarified benchmark scores using base 2 or base 10; for example 1GB/s = 1024MB/s = 1024*1024kB/s rather than 1GB/s = 1000MB/s, etc. While other OSes use the GiB/MiB units to denote base 2, these are not widespread in Windows.
– FMA3 (Intel) and FMA4 (AMD) support where faster than AVX; do note that as with GPUs, FMA is not always faster than a MUL-ADD thus we may need instrumentation upon testing on production hardware to optimise the code-paths.
– Further support in hardware monitoring with more chipset/CPU/video/battery sensors detected and displayed.
– Improved I/O in Physical Disks & File Systems Benchmarks: higher queue depth based on system thread availability (2-64). This helps SSD and RAID systems we tested score ~5-8% better. HDD performance does not change significantly.
Note: With Options you can disable overlapped/async I/O, i.e. use synchronous I/O (no queue). As a side-effect the min. performance is very low as blocks have to wait the whole queue to execute.
– GUI: Paint all graphs back-to-front, i.e. current results (red) are painted last, i.e. over the reference results. This ensures you always see the current result. Previously the reference results could obscure it.
– Update: AMD STREAM 2.5 for GPGPU.

Sandra késako ? Pour ceux qui ne le connaissent pas encore, sachez que SANDRA (pour System ANalyser, Diagnostic and Reporting Assistant) fournit de informations sur votre machine (carte mère, CPU, RAM, HDD, etc..) et permet également de tester les performances de chaque composant de votre PC. Un petit programme très pratique.
