GeForce GT 320 vs Radeon RX 570

Intro

Compare those specifications to the Radeon RX 570, which comes with a clock speed of 1168 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 256-bit bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Radeon RX 570		150 Watts
	Difference: 107 Watts (249%)

Memory Bandwidth

In theory, the Radeon RX 570 is 807% quicker than the GeForce GT 320 overall, due to its greater data rate. (explain)

Radeon RX 570		229376 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 204096 (807%)

Texel Rate

The Radeon RX 570 should be a lot (approximately 1054%) more effective at anisotropic filtering than the GeForce GT 320. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 136544 (1054%)

Pixel Rate

The Radeon RX 570 should be a lot (more or less 765%) better at FSAA than the GeForce GT 320, and also should be capable of handling higher resolutions better. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 33056 (765%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
