NVIDIA GeForce 9600 GSO: From rebranding in the air!

Despite a name that suggests a relationship with the GeForce 9600 GT, GeForce 9600 GSO truth that has little to do. While the GeForce 9600 GT is built on a G94 chip, the GeForce 9600 GSO it is structured around a G92, the G92 even behind already GeForce 8800 GT, GeForce 8800 GS and GeForce 9800 GTX particular. Technically, the characteristics of the G92, always engraved in 65 nm are naturally adjusted market covered by the GeForce 9600 GSO. It is thus an architecture DirectX 10 with 96 stream processors (against 64 only for the GeForce 9600 GT).

The game of the variations that where the GeForce 9600 GSO has more texture units that the GeForce 9600 GT, however it has fewer units ROP. As for the frequency of operation, they are inferior to those of a GeForce 9600 GT with 550 MHz for the graphics chip, 1 375 MHz processors feeds and 800 MHz for memory. This is interfaced to 192 bits, 256 bits and not as with the GeForce 9600 GT, and the reference map includes logically a quantity of video memory since no exotic set to 384 MB

NVIDIA GeForce 9500 GT: Beware … the rebranding!

Launched at the end of July, the GeForce 9500 GT NVIDIA is a new reference entry for NVIDIA. On closer look, the G96 that animating GeForce 9500 GT is actually a famous version of G86 that is at the heart of the GeForce 8600 GT chips since both share the same architecture and DirectX 10 same general characteristics with 32 stream processors and memory bus interfaced to 128 bits.

The move to G96 is still an opportunity for NVIDIA to review the operating frequency on the rise while the chip board now an PCI-Express second generation. The fineness of engraving is also evolving and while the GeForce 8600 was recorded in 80 nm, the GeForce 9500 GT is engraved in 65 nm. And NVIDIA to provide a future transition to burn in 55 nm in the coming months for this reference. Later operating frequencies, NVIDIA specifications are as follows: 550 MHz chip, 1 400 MHz processors feeds and 800 MHz for memory, in this case the DDR2 or GDDR3 as the model .

NVIDIA GeForce 9400 GT: a mere half of 9500 GT?

Launched at the end of August, the GeForce 9400 GT NVIDIA is other than a declination of the G96 behind the GeForce 9500 GT and is ultimately a slightly modernized version of the G86 or GeForce 8600 GT (Note: you follow?). Responding to the code name G96b, and engraved in 55 nm chip that drives the GeForce 9400 GT has half the stream processors, since they are 16. If there is a 128-bit memory interface, the map shows modest frequencies with 550 MHz for the chip, 1 400 MHz processors feeds, as the GeForce 9500 GT and therefore 400 MHz for memory.

NVIDIA CUDA technology & PhysX

Alongside the development of its graphics chips, NVIDIA is trying to put forward its CUDA and PhysX technology with its new entry level chip, solutions that in the eyes of the firm to the chameleon to differentiate the offer AMD. While all the graphics chips from NVIDIA GeForce 8 supports CUDA technology, a technology that allows the use of the GPU as a co-processor in traditional applications such as order to accelerate certain treatments such as video encoding, the number of applications CUDA general public is still very limited (Badaboom the converter is still in beta and not commercialized) and the performance of a GeForce 9400 or 9500 will be the subject frankly limited. For example, our GeForce 9500 GT has a score of 140n in Folding @ Home while a GeForce 9800 GTX claim the 560ns. Beyond the problematic score, if CUDA is certainly an interesting technology, it is not a valid argument for a variance chart sold around fifty euros.

On the PhysX, technology following the acquisition of AGEIA, NVIDIA is the possibility to use a GeForce 9400 or 9500 to accelerate the calculation of certain effects related to physics in games. Here we have a problem with the dual NVIDIA arguments: first, a GeForce 9400 or 9500 penalty already display fluidity with a game in full screen in a resolution down then ask him to calculate in addition to the physical effects would be suicidal. Secondly, the number of games optimized PhysX is still far too small to generate any enthusiasm towards these new opportunities. There remains the possibility of using a GeForce 9500 GT or 9400 GT as an accelerator dedicated exclusively to physics in conjunction with a more beefy graphics card as a GeForce 9600 GT or 9800 GT. Why not, if the number of games managing the PhysX technology finally takes off?

Finally, and use that could democratize in the future, the new version of the inevitable photo editing software, Photoshop CS4, uses the graphics chip using the OpenGL library to do some basic treatments on the image ( rotate and zoom). On our test machine, with a beta version of Photoshop CS4, these features were perfectly fluid on an image with a 17 MB GeForce 9500 GT.
