Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 340 1GB will be 55% faster than the Radeon R9 M375 overall, because of its greater data rate. (explain)

GeForce GT 340 1GB		54400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 19200 (55%)

Texel Rate

The Radeon R9 M375 should be quite a bit (approximately 131%) better at anisotropic filtering than the GeForce GT 340 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 23000 (131%)

Pixel Rate

The Radeon R9 M375 is a lot (approximately 269%) better at anti-aliasing than the GeForce GT 340 1GB, and should be able to handle higher resolutions more effectively. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 11840 (269%)

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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
