GeForce GT 420 vs Radeon R9 M375

Intro

The GeForce GT 420 features a core clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses 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 those specifications to the Radeon R9 M375, which features a core clock speed of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375 is 22% quicker than the GeForce GT 420 in general, because of its greater bandwidth. (explain)

Radeon R9 M375 35200 MB/sec
GeForce GT 420 28800 MB/sec
Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 will be quite a bit (more or less 625%) better at texture filtering than the GeForce GT 420. (explain)

Radeon R9 M375 40600 Mtexels/sec
GeForce GT 420 5600 Mtexels/sec
Difference: 35000 (625%)

Pixel Rate

The Radeon R9 M375 will be much (more or less 480%) better at full screen anti-aliasing than the GeForce GT 420, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M375 16240 Mpixels/sec
GeForce GT 420 2800 Mpixels/sec
Difference: 13440 (480%)

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 (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
