GeForce GTX 480 vs Radeon R9 270

Intro

The GeForce GTX 480 uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR5 memory runs at a speed of 924 MHz on this particular card. It features 480 SPUs along with 60 TAUs and 48 ROPs.

Compare those specifications to the Radeon R9 270, which has GPU clock speed of 900 MHz, and 2048 MB of GDDR5 memory running at 1400 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
