Radeon HD 6750 vs Radeon RX 460

Intro

Compare all that to the Radeon RX 460, which makes use of a 14 nm design. AMD has clocked the core frequency at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 896 SPUs as well as 56 TAUs 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

The Radeon RX 460, in theory, should be a lot faster than the Radeon HD 6750 overall. (explain)

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

Texel Rate

The Radeon RX 460 should be quite a bit (more or less 134%) better at AF than the Radeon HD 6750. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 460 is superior to the Radeon HD 6750, by a large margin. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per 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 sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
