GeForce GTX 465 vs Radeon R9 M280X

Intro

The GeForce GTX 465 uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory runs at a frequency of 802 MHz on this particular card. It features 352 SPUs along with 44 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M280X, which has a clock frequency of 900 MHz and a GDDR5 memory speed of 1375 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
