GeForce GT 220 GDDR3 vs Radeon R7 240

Intro

The GeForce GT 220 GDDR3 has clock speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 memory. It features 48 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare all of that to the Radeon R7 240, which makes use of a 28 nm design. AMD has clocked the core frequency at 730 MHz. The DDR3 RAM runs at a speed of 900 MHz on this particular card. It features 320 SPUs as well as 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 220 GDDR3 58 Watts
Difference: 28 Watts (93%)

Memory Bandwidth

In theory, the GeForce GT 220 GDDR3 should be 12% faster than the Radeon R7 240 in general, because of its greater bandwidth. (explain)

GeForce GT 220 GDDR3 32384 MB/sec
Radeon R7 240 28800 MB/sec
Difference: 3584 (12%)

Texel Rate

The Radeon R7 240 is much (about 46%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R7 240 14600 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 4600 (46%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 240 is superior to the GeForce GT 220 GDDR3, but it probably won't make a huge difference. (explain)

Radeon R7 240 5840 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 840 (17%)

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 maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
