GeForce GT 220 GDDR3 vs Radeon R7 240

Intro

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

Compare those specifications to the Radeon R7 240, which has GPU clock speed of 730 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is comprised of 320 SPUs, 20 TAUs, and 8 ROPs.

Radeon R7 240 28800 MB/sec
Difference: 3584 (12%)

Texel Rate

The Radeon R7 240 is a lot (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

The Radeon R7 240 will be a small bit (about 17%) better at full screen anti-aliasing than the GeForce GT 220 GDDR3, and should be capable of handling higher resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core clock 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 applied per second.

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