GeForce GT 320 vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which comes with a clock frequency of 1175 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Radeon RX 560		80 Watts
	Difference: 37 Watts (86%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 560 should be a lot faster than the GeForce GT 320 overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 89408 (354%)

Texel Rate

The Radeon RX 560 is a lot (more or less 480%) better at anisotropic filtering than the GeForce GT 320. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 62240 (480%)

Pixel Rate

The Radeon RX 560 is quite a bit (about 335%) faster with regards to full screen anti-aliasing than the GeForce GT 320, and should be capable of handling higher resolutions more effectively. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 14480 (335%)

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 data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
