Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M375X should be quite a bit faster than the GeForce GT 430 1GB overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 43200 (150%)

Texel Rate

The Radeon R9 M375X should be much (about 263%) better at texture filtering than the GeForce GT 430 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 29400 (263%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is superior to the GeForce GT 430 1GB, by far. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GT 430 1GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling 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 can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
