GeForce GT 310 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which comes with a core clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

GeForce GT 310		31 Watts
Radeon RX 470		120 Watts
	Difference: 89 Watts (287%)

Memory Bandwidth

In theory, the Radeon RX 470 will be 1220% faster than the GeForce GT 310 overall, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 470 is a lot (more or less 2415%) faster with regards to texture filtering 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 much (more or less 1158%) better at FSAA than the GeForce GT 310, and also should be able to handle higher resolutions more effectively. (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 max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
