GeForce GT 320 vs Radeon RX 470

Intro

Compare that to the Radeon RX 470, which comes with a core clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also makes use of a 256-bit memory bus, and makes use of a 14 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Radeon RX 470		120 Watts
	Difference: 77 Watts (179%)

Memory Bandwidth

In theory, the Radeon RX 470 will be 735% faster than the GeForce GT 320 in general, because of its higher bandwidth. (explain)

Radeon RX 470		211200 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 185920 (735%)

Texel Rate

The Radeon RX 470 should be much (approximately 815%) more effective at anisotropic filtering than the GeForce GT 320. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 105568 (815%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 470 is a better choice, and very much so. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 25312 (586%)

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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
