Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375 should in theory be much faster than the GeForce GT 430 1GB overall. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 will be a lot (approximately 263%) more effective at anisotropic filtering than the GeForce GT 430 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 29400 (263%)

Pixel Rate

The Radeon R9 M375 is quite a bit (about 480%) better at anti-aliasing than the GeForce GT 430 1GB, and capable of handling higher resolutions better. (explain)

Radeon R9 M375		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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its 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 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
