Radeon HD 6750 vs Radeon RX 460

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
Radeon HD 6750		86 Watts
	Difference: 11 Watts (15%)

Memory Bandwidth

In theory, the Radeon RX 460 should perform quite a bit faster than the Radeon HD 6750 in general. (explain)

Radeon RX 460		112000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 48000 (75%)

Texel Rate

The Radeon RX 460 should be much (about 134%) faster with regards to AF than the Radeon HD 6750. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 34940 (134%)

Pixel Rate

The Radeon RX 460 is a lot (more or less 50%) better at anti-aliasing than the Radeon HD 6750, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 5840 (50%)

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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
