GeForce GT 340 vs Radeon RX 560

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
Radeon RX 560		80 Watts
	Difference: 11 Watts (16%)

Memory Bandwidth

In theory, the Radeon RX 560 should perform quite a bit faster than the GeForce GT 340 in general. (explain)

Radeon RX 560		114688 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 60288 (111%)

Texel Rate

The Radeon RX 560 will be a lot (more or less 327%) more effective 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 (approximately 327%) better at anti-aliasing than the GeForce GT 340, and will 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
