Radeon HD 5750 1GB vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which features GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
Radeon HD 5750 1GB		86 Watts
	Difference: 11 Watts (15%)

Memory Bandwidth

In theory, the Radeon RX 460 is 52% faster than the Radeon HD 5750 1GB in general, because of its greater bandwidth. (explain)

Radeon RX 460		112000 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 38400 (52%)

Texel Rate

The Radeon RX 460 will be quite a bit (about 142%) better at AF than the Radeon HD 5750 1GB. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 35840 (142%)

Pixel Rate

The Radeon RX 460 should be a lot (more or less 56%) faster with regards to anti-aliasing than the Radeon HD 5750 1GB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 6240 (56%)

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 transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
