Unlike Nvidia's GeForce GTX 280 per desktop, based on the powerful GT200 graphics chip, the GeForce GTX 280M notebook version will use a slightly improved version of the old G92, with the production process reduced from 65nm to 55nm. The company has failed to reduce the size and time consumption of the chip GT200, to be able to implement in a notebook platform, then sending in producing video cards with a chip very similar.
The Nvidia GeForce GTX 200M could then be overtaken by the rival ATI Mobility Radeon HD4870, at least in the desktop version, it is closer in performance to Nvidia GT200-based chip, significantly better performance than the G92b. The GTX will be the version of the 260M 280M clocked lower, 550MHz, and a smaller number of Shaders, 112 to 1375Mhz, the amount of memory should be up to 1GB of 950MHz GDDR3 type, with channel 256bit. The Nvidia GTX 260M is expected to generate 462 gigaflops.
The NVIDIA GeForce GTX 260 is currently the second fastest single-chip graphics card from NVIDIA. It is suitable for players who want to reach the performance without compromise. The NVIDIA GeForce GTX 260 has a huge power hungry. The consequences are short battery life in notebooks equipped with this video card. In return, the NVIDIA GeForce GTX 260M full decoding of HD material from the processor. This can then be used for other tasks. The graphics processor based on a further development of the G92 (G92), is manufactured in 55 nm process and contains 754 million transistors. Of the 128 stream processors, 16 are disabled so that the card has 112 stream processors and 56 texture mapping units. The chip is clocked at 1,375 MHz, the memory at 950 MHz.
It is connected via a 256-bit wide line to the graphics processor, so that a bandwidth of up to 60.8 GB / sec. The computing power is theoretically impressive 462 GFlops. Notebooks with this video card can play current games in high resolutions and are prepared for the future.
Clocked at 590 MHz and equipped with 128 stream processors running at 1463 MHz, the GeForce GTX 280M is advertised as 21% to 57% faster than the 9800M GTX. The GeForce 9800M GTX GeForce GTX 260M displays similar characteristics, except the operating frequency of the GPU (550 MHz), and the number of Stream Processors limited to 112.
