GeForce GT 340 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which has GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 16 ROPs.

GeForce GT 340		54400 MB/sec
	Difference: 60288 (111%)

Texel Rate

The Radeon RX 560 will be much (approximately 327%) better at texture filtering than the GeForce GT 340. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 57600 (327%)

Pixel Rate

The Radeon RX 560 is much (about 327%) more effective at FSAA than the GeForce GT 340, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 14400 (327%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
