GeForce GT 320 vs Radeon R7 240

Intro

The GeForce GT 320 features a clock frequency of 540 MHz and a GDDR3 memory frequency of 790 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It features 72 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon R7 240, which features a GPU core clock speed of 730 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 128-bit bus. It also features 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

GeForce GT 320 25280 MB/sec
Difference: 3520 (14%)

Texel Rate

The Radeon R7 240 will be a bit (approximately 13%) better at anisotropic filtering than the GeForce GT 320. (explain)

Radeon R7 240 14600 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 1640 (13%)

Pixel Rate

The Radeon R7 240 will be much (approximately 35%) better at AA than the GeForce GT 320, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R7 240 5840 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 1520 (35%)

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 max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
