GeForce GT 430 (OEM) vs Radeon R5 M255

Intro

Compare those specs to the Radeon R5 M255, which comes with a GPU core clock speed of 940 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 430 (OEM), in theory, should perform much faster than the Radeon R5 M255 in general. (explain)

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

Texel Rate

The Radeon R5 M255 should be much (approximately 68%) more effective at anisotropic filtering 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 AA than the GeForce GT 430 (OEM), and will be able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
