GeForce GT 315 vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which comes with a core clock speed of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and uses a 14 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 315		52 Watts
Radeon RX 560		80 Watts
	Difference: 28 Watts (54%)

Memory Bandwidth

The Radeon RX 560 should in theory be quite a bit faster than the GeForce GT 315 in general. (explain)

Radeon RX 560		114688 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 89408 (354%)

Texel Rate

The Radeon RX 560 will be quite a bit (more or less 652%) more effective at anisotropic filtering than the GeForce GT 315. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 65200 (652%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 560 is a better choice, and very much so. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 13800 (276%)

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 max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
