Texel Rate

The Radeon R9 M395X is quite a bit (approximately 1864%) faster with regards to anisotropic filtering than the GeForce GT 310. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 87832 (1864%)

Pixel Rate

The Radeon R9 M395X is quite a bit (more or less 882%) better at anti-aliasing than the GeForce GT 310, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 20780 (882%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 ability to get to the maximum fill rate.
