GeForce GT 320 vs Radeon R9 M295X

Intro

The GeForce GT 320 makes use of a 40 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 RAM is set to run at a frequency of 790 MHz on this particular model. It features 72 SPUs along with 24 TAUs and 8 ROPs.

Compare those specs to the Radeon R9 M295X, which has a clock speed of 750 MHz and a GDDR5 memory frequency of 1375 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

GeForce GT 320 25280 MB/sec
Difference: 150720 (596%)

Texel Rate

The Radeon R9 M295X should be quite a bit (more or less 641%) better at AF than the GeForce GT 320. (explain)

Radeon R9 M295X 96000 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 83040 (641%)

Pixel Rate

The Radeon R9 M295X will be much (about 456%) more effective at AA than the GeForce GT 320, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M295X 24000 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 19680 (456%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 lots of 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.
