Categories: Benchmarks, Forceware, Test   Tags: , , , , ,

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.

BFGTech GeForce GTX 280 OCX Review

Be the first to comment - What do you think?  Posted by JeGX - 2008/07/29 at 10:28

Categories: Graphics Cards   Tags: , , , , ,

BFGTech’s GeForce GTX 280 OCX reviewed at [H]Enthusiast. This GeForce GTX 280 is compared to the stock-clocked GTX 280 as well as ATI’s best offering.

Read the complete review HERE.

The Verdict:
BFGTech has put out a solid product in the GeForce GTX 280 OCX, and they have made great progress towards bringing it down to a reasonable cost now. We do think that it is however a bit too expensive for the value it represents. The GTX 280 OCX does not game considerably better than a reference-clocked GeForce GTX 280, which costs a bit less.

The biggest problem right now for gamers is the games; we simply need more demanding games to see the kind of performance that the OCX branding is capable of. We don’t really have any games, except for Crysis to challenge these video cards.


XFX GeForce GTX 280 1GB XXX: Enough to stop the competition?

Be the first to comment - What do you think?  Posted by JeGX - 2008/07/27 at 17:58

At one point of time, the NVIDIA GT200 was thought to be a formidable chip that noone could touch, but it ended up getting tamed by ATI’s RV770. With ATI’s R700 coming round the corner and the current Radeon HD 4870 512MB making the GeForce GTX 260 896MB look ordinary, there are only two options: overclock the current GT200, or shrink it (GT200b).

VR-Zone has reviewed an overclocked NVIDIA GT200-based GeForce GTX 280 card from XFX, the XFX GeForce GTX 280 1GB XXX. You can read the complete review HERE.

The XFX GeForce GTX 280 1GB XXX has proven itself to be the fastest single card on the market at present. It ran flawlessly at its factory overclocked speeds of 670/1458/1250 without problems. Power consumption was just a little more than a reference GeForce GTX 280, coming in at a peak of 410W from the readout of our wall socket power meter. Temperatures were also kept in check, with the card idling at 46ºC and peaking at 79ºC during our load test. The XFX card’s fan behaviour was similiar and not any louder compared to the reference GeForce GTX 280.

For enthusiasts who find that the card still isn’t fast enough, there is still some headroom for overclocking, which by doing so, can rival a CrossFired ATI Radeon HD 4870 setup. As a general rule-of-thumb, make sure you have good cooling to ensure stable operation.

TT-Hardware nous propose un article comparatif des performances entre la GeForce GTX 280 et les Radeon HD 4870/4850.

Lire le test complete ICI.

La GeForce GTX 280 confirme qu’elle est bien la carte de tous les superlatifs : la plus grosse, la plus complexe, la plus performante mais aussi la plus encombrante, la plus bruyante, la plus gourmande et surtout la plus chère (de 460 € à plus de 500 €). Des points faibles qui pèsent lourd par rapport aux avantages surtout que la Radeon HD 4870 vient jouer les trouble-fêtes. En effet, si la Radeon HD 4870 est un peu en retrait par rapport à sa rivale, elle est surtout beaucoup moins chère (230 €) et nettement plus discrète. Sa seule contrepartie est une consommation importante au repos. La Radeon HD 4850 (moins de 160 €) est la révélation de ce comparatif : elle ne souffre d’aucun point faible. Ses prestations la mettent en concurrence avec la GeForce 8800 GTS OC MSI ainsi que les GeForce 9800 GTX et GTX+ (220 à 230 €). Ces dernières sont au moins 30% plus chères et nettement plus bruyantes et donc dans l’état actuel des choses sans le moindre intérêt ! Seules les GeForce 8800 GTS 512 Mo peuvent encore tirer leur épingle du jeu en raison d’un prix inférieur à 200 € et un silence de fonctionnement plus qu’appréciable. Particulièrement intéressante à son lancement, la GeForce 9600 GT est aujourd’hui caduque.

NVIDIA GeForce GTX280 SLI Performance Test

Be the first to comment - What do you think?  Posted by JeGX - 2008/07/10 at 10:44

Categories: Graphics Cards   Tags: , , , ,

The NVIDIA GTX 280 is easily the fastest gaming GPU at the moment and we thought we’d find out how well it does in a dual card setup. From past experiences, we’ve seen that SLI or Crossfire add quite a bit of overhead (SLI especially) and doubling the GPUs certainly doesn’t result in doubling the performance- far from it actually. We already had nVidia’s reference card and thus, when we received the ASUS GeForce GTX 280, we wanted to see how fast can it get with an SLI setup.

Read the complete review HERE.

As expected, the drivers aren’t quite ready for SLI. Games like ET: Quake Wars and Half Life 2 Episode 2 perform worse in an SLI setup on the GTX 280 than with a single card.

Conclusion- At the moment, a single GTX 280 is a much better option that two. With driver optimizations, this could change but certainly not for now.

ZOTAC GeForce GTX 280 AMP! Edition Video Card

Be the first to comment - What do you think?  Posted by JeGX - 2008/07/02 at 09:18

Categories: Graphics Cards   Tags: , , , ,

NVIDIA has recently launched the GeForce GTX 280 and GTX 260 video cards. Both the GTX 280 and GTX 260 products position themselves at the most elite segment of the GeForce product line, so just imagine how much more powerful the GeForce GTX 280 could become after ZOTAC give it their special AMP! Edition treatment. The recent Radeon HD 4870 launch may have shown how close ATI/AMD can get to NVIDIA’s bar of performance, but the ZOTAC GeForce GTX 280 AMP! Edition graphics card has just raised that bar much higher. Benchmark Reviews tests the ZOTAC ZT-X28E3LA-FCP against the GeForce 9800 GX2 and 9800 GTX, as well as the new Radeon HD 4850 in CrossFireX configuration.

GT200: Nvidia GeForce GTX 280 analysis

Be the first to comment - What do you think?  Posted by JeGX - at 09:02

Categories: Graphics Cards   Tags: , , , ,

bit-tech.net has published a 15-page article on the analysis of the GT200 GPU architecture, with some words about CUDA and PhysX.

Read the complete article HERE.

The 240 thread processors are split down into ten thread processing clusters (TPCs), with each broken down into three streaming multiprocessors (SMs) or thread processing arrays (TPAs). Threads are assigned by the thread scheduler, which talks directly to each streaming multiprocessor through a dedicated instruction unit; this then assigns tasks to one of eight thread (or stream) processors.

Expreview has just published a huge 25-page review about Radeon HD 4870 and 4850. Expreview compares Radeon 4870 and 4850 with other modern graphics cards such as Radeon HD 3870/3870 X2, GeForce GTX 280/260 and GeForce 9800 GTX.

Read the complete review HERE.


Radeon HD 4870


Radeon HD 4850

FurMark has been used to stress Radeon HD 4870 and 4850′s GPUs.

Final words
So, numbers can talk for itself. With the price tag $199(HD 4850) and $299 (HD 4870), RV770 is the BEST bang for the buck. Compare to GTX 260, A $299 only HD 4870 is a smarter choice. Yes, using this kind of word seems quite biased, but if you read all numbers from our review you will see my point.

Compare to GTX 260, HD 4870 is only 3/4 of its price while test items show the card have almost the same firepower!

HD 4850’s rival is 9800GTX, and we can see while their price keeps the same, HD 4850 have more than 15% leading.
