GeForce GTX 460 SE 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 frequency at 1100 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular model. It features 512 SPUs along with 32 TAUs and 16 ROPs.

GeForce GTX 460 SE		108800 MB/sec
	Difference: 5888 (5%)

Texel Rate

The Radeon RX 550 should be a small bit (more or less 13%) faster with regards to anisotropic filtering than the GeForce GTX 460 SE. (explain)

Radeon RX 550		35200 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 4000 (13%)

Pixel Rate

The GeForce GTX 460 SE is a small bit (about 18%) more effective at FSAA than the Radeon RX 550, and also capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 3200 (18%)

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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at 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 that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
