Radeon HD 5550 vs Radeon RX 460

Intro

Compare 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

As far as performance goes, the Radeon RX 460 should in theory be quite a bit better than the Radeon HD 5550 overall. (explain)

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

Texel Rate

The Radeon RX 460 is much (approximately 594%) faster with regards to anisotropic filtering than the Radeon HD 5550. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 460 is superior to the Radeon HD 5550, by far. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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