GeForce GT 430 vs Radeon R5 M255

Intro

Compare that to the Radeon R5 M255, which has core clock speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 430 should perform a lot faster than the Radeon R5 M255 in general. (explain)

GeForce GT 430		28800 MB/sec
Radeon R5 M255		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The Radeon R5 M255 is a lot (about 68%) more effective at AF than the GeForce GT 430. (explain)

Radeon R5 M255		18800 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 7600 (68%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R5 M255 is a better choice, and very much so. (explain)

Radeon R5 M255		7520 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 4720 (169%)

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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
