GeForce GT 315 vs Radeon RX 470

Intro

Compare that to the Radeon RX 470, which comes with GPU core speed of 926 MHz, and 8192 MB of GDDR5 RAM set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

GeForce GT 315		25280 MB/sec
	Difference: 185920 (735%)

Texel Rate

The Radeon RX 470 will be quite a bit (about 1085%) faster with regards to texture filtering than the GeForce GT 315. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 108528 (1085%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 470 is a better choice, by a large margin. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 24632 (493%)

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 (measured in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate 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 of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
