GeForce 8800 Ultra vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which uses a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory works at a speed of 1750 MHz on this card. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 121 Watts (242%)

Memory Bandwidth

In theory, the Radeon RX 550 should perform a bit faster than the GeForce 8800 Ultra overall. (explain)

Radeon RX 550		114688 MB/sec
GeForce 8800 Ultra		103680 MB/sec
	Difference: 11008 (11%)

Texel Rate

The GeForce 8800 Ultra is a bit (about 11%) faster with regards to AF than the Radeon RX 550. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 3968 (11%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 550 is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 2912 (20%)

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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
