GeForce 9800 GTX vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which comes with core clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce 9800 GTX		140 Watts
	Difference: 90 Watts (180%)

Memory Bandwidth

The Radeon RX 550 should theoretically be quite a bit faster than the GeForce 9800 GTX in general. (explain)

Radeon RX 550		114688 MB/sec
GeForce 9800 GTX		70400 MB/sec
	Difference: 44288 (63%)

Texel Rate

The GeForce 9800 GTX is quite a bit (approximately 23%) better at AF than the Radeon RX 550. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 8000 (23%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 550 is the winner, and very much so. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 6800 (63%)

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 (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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 max fill rate.
