GeForce GT 420 vs Radeon R7 M260X

Intro

The GeForce GT 420 comes with a core clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Compare all of that to the Radeon R7 M260X, which has core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X, in theory, should perform quite a bit faster than the GeForce GT 420 in general. (explain)

Radeon R7 M260X 64000 MB/sec
GeForce GT 420 28800 MB/sec
Difference: 35200 (122%)

Texel Rate

The Radeon R7 M260X will be a lot (more or less 254%) more effective at anisotropic filtering than the GeForce GT 420. (explain)

Radeon R7 M260X 19800 Mtexels/sec
GeForce GT 420 5600 Mtexels/sec
Difference: 14200 (254%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 M260X is the winner, by a large margin. (explain)

Radeon R7 M260X 6600 Mpixels/sec
GeForce GT 420 2800 Mpixels/sec
Difference: 3800 (136%)

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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface 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 better 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 per second. This number 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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