GeForce 9800 GTX+ vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which has GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 512 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 95 Watts (190%)

Memory Bandwidth

In theory, the Radeon RX 550 will be 63% quicker than the GeForce 9800 GTX+ overall, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GTX+ should be a lot (approximately 34%) better at AF than the Radeon RX 550. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 12032 (34%)

Pixel Rate

If running with 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+		11808 Mpixels/sec
	Difference: 5792 (49%)

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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
