Radeon HD 6750 vs Radeon RX 470

Intro

Compare that to the Radeon RX 470, which uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 RAM runs at a frequency of 1650 MHz on this card. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
Radeon RX 470		120 Watts
	Difference: 34 Watts (40%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 should be quite a bit faster than the Radeon HD 6750 in general. (explain)

Radeon RX 470		211200 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 147200 (230%)

Texel Rate

The Radeon RX 470 will be a lot (about 354%) better at anisotropic filtering than the Radeon HD 6750. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 92428 (354%)

Pixel Rate

The Radeon RX 470 should be much (approximately 155%) more effective at AA than the Radeon HD 6750, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 18032 (155%)

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 max amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once 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 AA, High Dynamic Range and higher screen 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 number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few 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.
