GeForce GT 220 GDDR3 vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which has core clock speeds of 926 MHz on the GPU, and 1650 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

	Difference: 178816 (552%)

Texel Rate

The Radeon RX 470 4GB should be quite a bit (more or less 1085%) better at AF than the GeForce GT 220 GDDR3. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 108528 (1085%)

Pixel Rate

The Radeon RX 470 4GB is much (approximately 493%) more effective at AA than the GeForce GT 220 GDDR3, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 24632 (493%)

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 (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated 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 processed in a 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. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
