GeForce GT 320 vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which features a core clock frequency of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Radeon RX 550		35200 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 22240 (172%)

Pixel Rate

The Radeon RX 550 will be quite a bit (approximately 307%) more effective at anti-aliasing than the GeForce GT 320, and able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 13280 (307%)

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 data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
