[Geeks3D-Test] ForceWare 177.79 vs 177.39 – OpenGL Side

Expreview has published a post about performance improvements of ForceWare 177.79 versus 175.19. From the results, it seems the release 177.79 brings a small 2% of improvement. That’s cool but how the release 177.79 is positionned with another 177.xx, what’s more in OpenGL?

I did the test: ForceWare 177.39 versus ForceWare 177.79 and I benched with oZone3D.Net OpenGL benchmarks. Some of these benchies are rather old (soft shadows and Surface Deformer and we can’t change the benchmark resolution). My rig is: Core 2 Duo 6600 (default clock), 2Gb Corsair DDR2 667 (default clocks) and a GeForce GTX 280 from EVGA (default clocks).

	Release 177.39	Release 177.79
FurMark 1920×1200	3172	3173
FurMark 1280×1024	4264	4270
Soft Shadows Branching OFF	6053	5814
Soft Shadows Branching ON	10191	9532
Surface Deformer	7713	7717
TOTAL Sum	31393	30506

From this test, there is no OpenGL performance improvement in this new release compared to the old one. Better we can notice some performance deterioration in the soft shadows benchmark.

As soon as possible, I will update SofShadows and SurfaceDeformer with the same interface than FurMark.

NVIDIA CUDA: One Year After

The hardware.fr staff has been invited by NVIDIA to make a point on CUDA. Since this exellent article is written in french, I’ll try to highlight the interesting parts.

One of the new thing in CUDA 2.0 is, according to hardware.fr, the adding in the CUDA compiler of an optimzed profile for multicores x86 CPUs. Currently, CUDA code is splitted in two parts: one part processed by the CPU and the other one by the GPU via the CUDA compiler.
The new thing is that we can now compile the GPU code explicitly for the CPU in order to take advantage of multicores capabilities of the latest CPUs.

Another new thing is Tesla Series 10. NVIDIA has equiped all Tesla 10 products with 4Gb of graphics memory by GPU (recall that GeForce GTX 280 has 1Gb of memory). This boost in memory amount is useful in situations where dataset to be processed are very large.

A Tesla 10 card has only 6-pin PCI-Express power connector (the 8-pin is optional – a GeForce GTX 280 has one 6-pin and one 8-pin an both are required!). The reason is in GPU Computing the GPU has a lower power consumption because some transitors dedicated to 3D graphics are not used.

The article shows also some practical cases where CUDA is used: financial analysis, medical imagery (3D scans) and password recovering.

Advanced Overclocking Championship 2008

Dragon City in Hong Kong: Advanced Overclocking Championship 08

The competitors will have to make use of hardware modifications on the supplied hardware, their knowledge of liquid nitrogen cooling and software tweaking to aid them in their course (or discourse) during the event. Goal: break the 3DMark score by overclocking to the max CPUs and GPUs!

NVIDIA GeForce 9500 GT Review

PC Perspective has published a review on the latest GeForce, I mean the GeForce 9500 GT. This level entry card aims at replace the old GeForce 8600 GT and to compete with ATI’s Radeon HD 3650.

The GeForce 9500 GT card has a simple single-slot cooler design that is not at all noisy and no power connection is required other than the power provided by the PCI Express bus.

Jump to the complete review HERE

GeForce 9500 GT’s features:

• based on G92 technology
• built on a 65nm process technology
• 314 million transistors
• 32 shader processors
• core clock: 550 MHz
• memory interface: 128-bit
• 256Mb of GDDR3
• 8 ROPs
• 16 texture units

GPU-Z is not really up to date, some values are good while other are wrong (ROPs) or missing
