GeForce GTX 465 vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which makes use of a 14 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Radeon RX 550		50 Watts
GeForce GTX 465		200 Watts
	Difference: 150 Watts (300%)

Memory Bandwidth

In theory, the Radeon RX 550 should be a little bit faster than the GeForce GTX 465 in general. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 12096 (12%)

Texel Rate

The Radeon RX 550 is a lot (more or less 32%) better 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 will be a small bit (about 10%) faster with regards to FSAA than the Radeon RX 550, and also should be capable of handling higher screen resolutions more effectively. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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