GeForce GT 220 GDDR3 vs Radeon RX 460

Intro

Compare that to the Radeon RX 460, which features GPU core speed of 1090 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
Radeon RX 460		75 Watts
	Difference: 17 Watts (29%)

Memory Bandwidth

Performance-wise, the Radeon RX 460 should in theory be much superior to the GeForce GT 220 GDDR3 overall. (explain)

Radeon RX 460		112000 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 79616 (246%)

Texel Rate

The Radeon RX 460 will be much (more or less 510%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 51040 (510%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 460 is superior to the GeForce GT 220 GDDR3, and very much so. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 12440 (249%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses 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 are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
