GeForce GTX 285 2GB vs Radeon R9 M295X

Intro

The GeForce GTX 285 2GB makes use of a 55 nm design. nVidia has clocked the core speed at 648 MHz. The GDDR3 memory runs at a speed of 1242 MHz on this model. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Compare those specs to the Radeon R9 M295X, which features a GPU core clock speed of 750 MHz, and 4096 MB of GDDR5 memory running at 1375 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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 one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
