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.

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.
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.

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.

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

The Medusa demo is a NVIDIA’s interpretation of the legendary snake-headed woman who’s venemous gaze turned her victims to stone. You’ll see we’ve taken a few liberties on this mythological tale.

Beyond3D has published a very detailed article on the architecture of the GT200, the GPU behind the GeForce GTX 280.
Read tHe complete analysis HERE.
If it’s not clear from the above diagram, like G80, GT200 is a fully-unified, heavily-threaded, self load-balancing (full time, agnostic of API) shading architecture. It has decoupled and threaded data processing, allowing the hardware to fully realise the goal of hiding sampler latency by scheduling sampler threads independently of, and asynchronously with, shading threads.
Benchmark Reviews has published a detailed review of NVIDIA’s new monster, the GeForce GTX 280.
The full review is accessible HERE.
In regards to performance and functionality, NVIDIA has redefined the graphics card space. Beginning with 240 processor cores, the GeForce GTX 280 is everything that previous products has not been: parallel-computing ready. Without question, the GeForce GTX 280 has earned the top position for NVIDIA’s video card product lineup. The core, shader, and memory clocks are at the launch-date reference level, so it might be a short while before drivers are stable enough to gain stable overclocks. Optimized post process compression combined with a future-proof 1024 MB of video frame buffer will make this the must-have card for extreme gamers for the foreseeable future.
The NDA is over. So all major hardware websites will publish in the next hours/days the reviews about the new NVIDIA flagship: the GeForce GTX 280.
Guru3D is one of the first to offer you such a review: NVIDIA GeForce GTX 280 review.
The GT200, the GPU with 1.4 billions transistors! Here are the main features:
* 993 GigaFLOP processing power
* 240 processing (shader) cores (GTX 280)
* 192 processing (shader) cores (GTX 260)
* DirectX 10 – OpenGL 2.1
* New power management enhancements
* CUDA parallel processing
* GeForce PhysX
We have to admit, the GeForce GTX 280 is simply put – a Greek power house. Spaaaartaaans!
Strangely enough there is another product out there that can actually compete with the GeForce GTX 280 rather well. It’s NVIDIA’s own GeForce 9800 GX2.
When we reverse things and look at the 9800 GX2, the GX2 however has 2x 128= 256 shader cores opposed to the 240 on the GTX 280 … that gives it a bit more bite and the GX2 shader domain is clocked a tad faster. So as this article has shown, the products both win and lose a little from each other.
Now then, if you’d ask me; the final word as far as I’m concerned is that the GTX 280 is the way to go here. Yes it’ll be more (too) expensive but with the GX2 you also have the problems that come with SLI, a lot of heat (2 GPUs) and a fair amount of power consumption. When games start using that excessive amount of frame buffer and complex shaders, the GTX 280 would seriously kick in.
The chaps over at VR-Zone have managed to bench a NVIDIA GeForce GTX 280 1Gb.

Apparently preliminary testing did not show any jaw-dropping results. The NVIDIA GeForce GTX 280 can be considered as somewhat of a ‘re-work’ of the GeForce 9800 GX2 into a single core package with faster processing capability and more bandwidth.
According to current plan, confirmed by high ranked Nvidia executives, a driver that will drive PhysX on Geforce 8 and 9 GPUs will come at least a few weeks after announcement of GTX 280.
It will be interesting to compare the performances fo Ageia card to the actually Geforce PhysX scores.
