GeForce GT 320 vs Radeon R7 240

Intro

The GeForce GT 320 comes with core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs as well as 24 Texture Address Units and 8 ROPs.

Compare all of that to the Radeon R7 240, which comes with core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240 30 Watts
GeForce GT 320 43 Watts
Difference: 13 Watts (43%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 240 should be 14% faster than the GeForce GT 320 in general, because of its greater bandwidth. (explain)

Radeon R7 240 28800 MB/sec
GeForce GT 320 25280 MB/sec
Difference: 3520 (14%)

Texel Rate

The Radeon R7 240 should be a little bit (more or less 13%) more effective at texture 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%) more effective at anti-aliasing than the GeForce GT 320, and also 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 are processed in one second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
