GeForce GT 340 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which features core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 470 should be 288% quicker than the GeForce GT 340 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 470 should be a lot (about 573%) more effective at texture filtering than the GeForce GT 340. (explain)

Radeon RX 470		118528 Mtexels/sec
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 is superior to the GeForce GT 340, by a large margin. (explain)

Radeon RX 470		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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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. Pixel rate is calculated by multiplying the amount of ROPs by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
