GeForce GT 340 vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this card. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 550		35200 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 17600 (100%)

Pixel Rate

The Radeon RX 550 is a lot (about 300%) faster with regards to AA than the GeForce GT 340, and capable of handling higher resolutions better. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 13200 (300%)

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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
