GeForce GT 340 1GB vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which comes with a core clock frequency of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Texel Rate

The Radeon RX 550 should be quite a bit (approximately 100%) faster with regards to AF than the GeForce GT 340 1GB. (explain)

Radeon RX 550		35200 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 17600 (100%)

Pixel Rate

The Radeon RX 550 will be much (approximately 300%) better at AA than the GeForce GT 340 1GB, and also capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GT 340 1GB		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 max amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
