GeForce GT 315 vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which features a core clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

GeForce GT 315		10000 Mtexels/sec
	Difference: 51040 (510%)

Pixel Rate

The Radeon RX 460 should be much (approximately 249%) more effective at anti-aliasing than the GeForce GT 315, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 12440 (249%)

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 (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
