Radeon HD 7750 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has clocked the core frequency at 1090 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this specific model. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
Radeon RX 460 2GB		75 Watts
	Difference: 20 Watts (36%)

Memory Bandwidth

The Radeon RX 460 2GB should in theory perform much faster than the Radeon HD 7750 in general. (explain)

Radeon RX 460 2GB		112000 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 40000 (56%)

Texel Rate

The Radeon RX 460 2GB should be a lot (more or less 138%) more effective at anisotropic filtering than the Radeon HD 7750. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 35440 (138%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 460 2GB is a better choice, by a large margin. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 4640 (36%)

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 (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling 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 can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
