Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 1GB		69 Watts
Radeon R9 M295X		125 Watts
	Difference: 56 Watts (81%)

Memory Bandwidth

In theory, the Radeon R9 M295X is 224% quicker than the GeForce GT 340 1GB in general, because of its greater data rate. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 121600 (224%)

Texel Rate

The Radeon R9 M295X should be a lot (about 445%) better at texture filtering than the GeForce GT 340 1GB. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 78400 (445%)

Pixel Rate

The Radeon R9 M295X is quite a bit (approximately 445%) better at AA than the GeForce GT 340 1GB, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 19600 (445%)

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 data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
