GeForce GT 310 vs Radeon R9 M375X

Intro

Compare that to the Radeon R9 M375X, which comes with GPU clock speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 310		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M375X should be a lot (more or less 762%) more effective at AF than the GeForce GT 310. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 35888 (762%)

Pixel Rate

The Radeon R9 M375X should be a lot (about 589%) faster with regards to full screen anti-aliasing than the GeForce GT 310, and also will be able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 13884 (589%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
