GeForce GTX 465 vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which features clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

GeForce GTX 465		102592 MB/sec
	Difference: 12096 (12%)

Texel Rate

The Radeon RX 550 is quite a bit (approximately 32%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)

Radeon RX 550		35200 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 8492 (32%)

Pixel Rate

The GeForce GTX 465 should be a little bit (about 10%) more effective at AA than the Radeon RX 550, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 1824 (10%)

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 megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 max fill rate.
