GeForce GT 340 1GB vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory is set to run at a speed of 1650 MHz on this model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

GeForce GT 340 1GB		69 Watts
Radeon RX 470		120 Watts
	Difference: 51 Watts (74%)

Memory Bandwidth

In theory, the Radeon RX 470 should be 288% faster than the GeForce GT 340 1GB in general, because of its higher data rate. (explain)

Radeon RX 470		211200 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 156800 (288%)

Texel Rate

The Radeon RX 470 should be much (approximately 573%) faster with regards to texture filtering than the GeForce GT 340 1GB. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 100928 (573%)

Pixel Rate

The Radeon RX 470 should be much (about 573%) more effective at anti-aliasing than the GeForce GT 340 1GB, and also should be able to handle higher resolutions better. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 25232 (573%)

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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
