GeForce GT 315 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which uses a 14 nm design. AMD has set the core frequency at 1175 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this specific card. It features 1024 SPUs along with 64 TAUs and 16 ROPs.

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

In theory, the Radeon RX 560 is 354% faster than the GeForce GT 315 in general, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 560 is quite a bit (more or less 652%) better 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

The Radeon RX 560 should be a lot (about 276%) better at anti-aliasing than the GeForce GT 315, and also capable of handling higher resolutions better. (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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
