Radeon R9 M295X		176000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 147200 (511%)

Texel Rate

The Radeon R9 M295X should be much (about 757%) better at anisotropic filtering than the GeForce GT 430 1GB. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 84800 (757%)

Pixel Rate

The Radeon R9 M295X is much (approximately 757%) faster with regards to FSAA than the GeForce GT 430 1GB, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 21200 (757%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
