Radeon HD 6770 vs Radeon RX 460

Intro

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

Radeon HD 6770		67200 MB/sec
	Difference: 44800 (67%)

Texel Rate

The Radeon RX 460 is quite a bit (about 70%) more effective at anisotropic filtering than the Radeon HD 6770. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 6770		36000 Mtexels/sec
	Difference: 25040 (70%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 460 is a better choice, and very much so. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 6770		14400 Mpixels/sec
	Difference: 3040 (21%)

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 megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 per 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 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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.
