Radeon HD 5550 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which features clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 460, in theory, should be quite a bit faster than the Radeon HD 5550 in general. (explain)

Radeon RX 460		112000 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 99200 (775%)

Texel Rate

The Radeon RX 460 is much (about 594%) better at texture filtering than the Radeon HD 5550. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 52240 (594%)

Pixel Rate

The Radeon RX 460 is quite a bit (approximately 296%) faster with regards to FSAA than the Radeon HD 5550, and also capable of handling higher resolutions better. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 13040 (296%)

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 max amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
