Quick Review – HWMonitor 1.0.5.8

HWMonitor pour, vous l’aurez sans doute deviné, HardWare Monitor est un tout petit utilitaire (732k) dont le but, réchauffement climatique oblige, est d’afficher les différentes températures du PC: CPU, GPU, disques durs, chipset ainsi que les tenions d’alimentation.

Sur ma machine de test voilà ce que ça donne:



Température du CPU


Température du GPU


Température du disque dur


Température du chipset

HWMonitor ne nessécite pas d’installation, est simple d’utilisation et fonctionne bien. A avoir dans sa toolbox!

La homepage de ce petit tool se trouve ici: www.cpuid.com/hwmonitor.php.


Quick Review – CrasyBump

Voilà un petit tool qui ravira les créateurs de scènes 3d temps réel (avec Demoniak3D? qui a dit Demoniak3D ? non ya pas que Demoniak3D, il y a d’autres soft aussi…).

Il s’agit d’un petit utilitaire qui permet de créer des normal-maps à partir d’une image en couleurs ou en valeurs de gris. Il est simple, rempli correctement sa fonction (ainsi que quelques autres que j’ai pas analysées) et est gratuit. A avoir dans sa toolbox de geek 3d :thumbup:


Dynamic branching and NVIDIA Forceware Drivers

Several weeks ago, I posted on Beyond3D a thread on my dynamic branching benchmark. I wondered why dynamic branching performances on Geforce 7 were worse than ones on Geforce 6 or 8. I believe I’ve got the answer: Forceware drivers.

Here are some new results where ratio = Branching_ON / Branching_OFF :

7600GS – Fw 84.21 – Branching OFF: 496 o3Marks – Branching ON: 773 o3Marks – Ratio = 1.5
7600GS – Fw 91.31 – Branching OFF: 509 o3Marks – Branching ON: 850 o3Marks – Ratio = 1.6
7600GS – Fw 91.36 – Branching OFF: 508 o3Marks – Branching ON: 850 o3Marks – Ratio = 1.6
7600GS – Fw 91.37 – Branching OFF: 509 o3Marks – Branching ON: 850 o3Marks – Ratio = 1.6

7600GS – Fw 91.45 – Branching OFF: 509 o3Marks – Branching ON: 472 o3Marks – Ratio = 0.9
7600GS – Fw 91.47 – Branching OFF: 509 o3Marks – Branching ON: 472 o3Marks – Ratio = 0.9
7600GS – Fw 93.71 – Branching OFF: 508 o3Marks – Branching ON: 474 o3Marks – Ratio = 0.9
7600GS – Fw 97.92 – Branching OFF: 505 o3Marks – Branching ON: 478 o3Marks – Ratio = 0.9
7600GS – Fw 100.95 – Branching OFF: 508 o3Marks – Branching ON: 480 o3Marks – Ratio = 0.9

my conclusion is: dynamic branching in OpenGL works fine (read the performance are better than without dynamic branching: ratio > 1) for forceware < = 91.37. For the drivers >= 91.45, the ratio drops under 1. Dynamic branching works as expected for gf6 and gf8 but not for gf7 since forceware 91.45. So the bug explanation is a plausible answer (and it’s easily understandable: in this news we learnt that a forceware driver is made of around 20 millions of lines of code – a paradise for a small bug!!!). I’ve also done the test with the simple soft shadows demo provided with the NV SDK 9.5. The results are the same.

I’ve just done the bench with a 7950gx2 and the latest forceware 160.02 and dynamic branching is still buggy…


Quick Review – Asus Silient Square Pro

Voilà le nouveau ventirad pour le cpu que j’ai installé sur ma machine de test:

Je dois dire que j’en suis assez satisfait. Facile à installer, ce ventirad d’Asus est quasiment inaudible. Et il rempli à merveille sa fonction de dissipation car les aillettes restent froides en permanence. Evidemment, je pense que c’est mon AMD X2 3800+ qui ne chauffe pas assez mais par rapport au ventirad d’origine livré avec le cpu, la différence est nette.

Du bon matos :thumbup:


SLI is nice!

I must confess the SLI is a really cool technology. I assembled a SLI station based on the new nVidia Geforce 7600 GS series. This is a little graphic card compared to the high-end ones like the 7900GTX or the big monster 7950 GX2 (which in passing is really quiet in spite of its two GPUs and ventirads): the price of a 7600GS is about 100 euros, the price of a 7900GTX is about 400 euros and the cost of the 7950 GX2 climbs up to 500 euros! In terms of shader pipelines, the 7600 GS has 5 vertex pipes and 12 pixel pipes, the 7900 GTX has 8 vertex pipes / 24 pixel pipes and the GX2 has 48 pixel pipes and 16 vertex pipes. And so what? A 7600 GS SLI system offers almost the same level of gpu power than a 7800/7900 for a half price. I’ve verified this fact with the latest version of the soft shadows benchmark. With one 7600 GS (single GPU mode) the score is 510 o3Marks. With the two 7600 GS in SLI mode, the score jumps to 1004 o3Marks. The 7950 GX2’s score in single GPU is about 1200 o3Marks. Ok my bench is a small bench, you’re right. What about 3dmrk06? The 3DMark06 score is 4115 for the 7600 GS SLI system. This score is close to the ones got with a non-overclocked gf7800/7900.

Little remark: my 7600 GS are not overclocked.

Conlusion: for 200 euros you can have an excellent graphic system which is also silent thanks to the 7600GS passive cooler!
