GeForce GTX 260 Core 216 vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which features GPU core speed of 1100 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 152 Watts (304%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 should be 3% faster than the GeForce GTX 260 Core 216 in general, because of its higher data rate. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 2800 (3%)

Texel Rate

The GeForce GTX 260 Core 216 is a little bit (about 18%) faster with regards to texture filtering than the Radeon RX 550. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 6272 (18%)

Pixel Rate

The Radeon RX 550 should be a small bit (approximately 9%) more effective at FSAA than the GeForce GTX 260 Core 216, and will be able to handle higher screen resolutions better. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 1472 (9%)

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 max amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its 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 clock 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 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.
