GeForce GT 240 GDDR5 vs Radeon HD 7750

Intro

The GeForce GT 240 GDDR5 has a clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 ROPs.

Compare all that to the Radeon HD 7750, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Theoretically speaking, the Radeon HD 7750 should be 32% faster than the GeForce GT 240 GDDR5 in general, because of its higher data rate. (explain)

Radeon HD 7750 72000 MB/sec
GeForce GT 240 GDDR5 54400 MB/sec
Difference: 17600 (32%)

Texel Rate

The Radeon HD 7750 is much (about 45%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

Radeon HD 7750 25600 Mtexels/sec
GeForce GT 240 GDDR5 17600 Mtexels/sec
Difference: 8000 (45%)

Pixel Rate

The Radeon HD 7750 should be a lot (about 191%) faster with regards to FSAA than the GeForce GT 240 GDDR5, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon HD 7750 12800 Mpixels/sec
GeForce GT 240 GDDR5 4400 Mpixels/sec
Difference: 8400 (191%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, 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 the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
