GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 460 2GB

Intro

The GeForce 9500 GT 1GB GDDR3 features a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specifications to the GeForce GTX 460 2GB, which comes with GPU clock speed of 675 MHz, and 2048 MB of GDDR5 memory set to run at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
