GeForce GT 220 GDDR3 vs Radeon R7 M260

Intro

Compare that to the Radeon R7 M260, which has a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 220 GDDR3 is 102% faster than the Radeon R7 M260 overall, due to its higher data rate. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 16384 (102%)

Texel Rate

The Radeon R7 M260 will be quite a bit (more or less 72%) better at texture filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 7160 (72%)

Pixel Rate

The Radeon R7 M260 is a little bit (more or less 14%) better at AA than the GeForce GT 220 GDDR3, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 720 (14%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
