GeForce GT 320 vs Radeon RX 560

Intro

The GeForce GT 320 makes use of a 40 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 memory runs at a speed of 790 MHz on this specific card. It features 72 SPUs as well as 24 Texture Address Units and 8 ROPs.

Compare all of that to the Radeon RX 560, which features GPU core speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 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, the Radeon RX 560 should perform 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 will be quite a bit (about 480%) more effective 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

If running with a high screen resolution is important to you, then the Radeon RX 560 is the winner, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
