GeForce 8800 Ultra vs Radeon RX 550

Intro

The GeForce 8800 Ultra makes use of a 90 nm design. nVidia has set the core frequency at 612 MHz. The GDDR3 RAM is set to run at a frequency of 1080 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.

Compare those specifications 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 is set to run at a speed of 1750 MHz on this specific card. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

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

Memory Bandwidth

As far as performance goes, the Radeon RX 550 should in theory be a small bit superior to the GeForce 8800 Ultra in general. (explain)

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

Texel Rate

The GeForce 8800 Ultra is a small bit (approximately 11%) better at anisotropic filtering than the Radeon RX 550. (explain)

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

Pixel Rate

The Radeon RX 550 will be a small bit (more or less 20%) better at AA than the GeForce 8800 Ultra, and also should be able to handle higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video 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 the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
