Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 430 (OEM) should be 80% quicker than the Radeon R5 M255 in general, due to its greater data rate. (explain)

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

Texel Rate

The Radeon R5 M255 will be quite a bit (more or less 68%) faster with regards to AF than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

The Radeon R5 M255 is a lot (approximately 169%) more effective at anti-aliasing than the GeForce GT 430 (OEM), and also will be capable of handling higher resolutions more effectively. (explain)

Radeon R5 M255		7520 Mpixels/sec
GeForce GT 430 (OEM)		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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per 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 the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
