GeForce GT 310 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which has GPU clock speed of 926 MHz, and 8192 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Memory Bandwidth

As far as performance goes, the Radeon RX 470 should in theory be much better than the GeForce GT 310 in general. (explain)

Radeon RX 470		211200 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 195200 (1220%)

Texel Rate

The Radeon RX 470 is much (approximately 2415%) faster with regards to AF than the GeForce GT 310. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 113816 (2415%)

Pixel Rate

The Radeon RX 470 is quite a bit (more or less 1158%) faster with regards to AA than the GeForce GT 310, and also should be able to handle higher resolutions better. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 27276 (1158%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core 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 fill rate also depends 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.
