GeForce GTX 260 216SP 55 nm vs GeForce GTX 460 (OEM)

Intro

The GeForce GTX 260 216SP 55 nm features a clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit memory bus, and makes use of a 55 nm design. It is comprised of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.

Compare all of that to the GeForce GTX 460 (OEM), which features a GPU core clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 850 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
