GeForce GT 340 vs Radeon RX 470 4GB

Intro

Compare those specs to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 memory is set to run at a speed of 1650 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

GeForce GT 340		17600 Mtexels/sec
	Difference: 100928 (573%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 470 4GB is the winner, by far. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GT 340		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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that are 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 this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
