GeForce GTX 465 vs Radeon RX 550

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 is 12% faster than the GeForce GTX 465 in general, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 550 is quite a bit (approximately 32%) faster with regards to texture filtering than the GeForce GTX 465. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 465 is superior to the Radeon RX 550, but it probably won't make a huge difference. (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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better 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 maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
