GeForce GTX 260 vs Radeon RX 550

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 260		182 Watts
	Difference: 132 Watts (264%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 should be a small bit faster than the GeForce GTX 260 in general. (explain)

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

Texel Rate

The GeForce GTX 260 should be a small bit (about 5%) faster with regards to texture filtering than the Radeon RX 550. (explain)

GeForce GTX 260		36864 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 1664 (5%)

Pixel Rate

The Radeon RX 550 is a bit (approximately 9%) better at FSAA than the GeForce GTX 260, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GTX 260		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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
