GeForce GT 220 GDDR3 vs Radeon R7 M265

Intro

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

Compare those specifications to the Radeon R7 M265, which has a clock frequency of 725 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 220 GDDR3 should be a bit faster than the Radeon R7 M265 in general. (explain)

GeForce GT 220 GDDR3 32384 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 384 (1%)

Texel Rate

The Radeon R7 M265 should be quite a bit (about 74%) better at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R7 M265 17400 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 7400 (74%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 M265 is the winner, but it probably won't make a huge difference. (explain)

Radeon R7 M265 5800 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 800 (16%)

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 (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
