GeForce 8800 GT 512MB vs Radeon RX 470

Intro

Compare all that to the Radeon RX 470, which makes use of a 14 nm design. AMD has clocked the core frequency at 926 MHz. The GDDR5 memory works at a frequency of 1650 MHz on this model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Pixel Rate

The Radeon RX 470 is much (about 209%) better at AA than the GeForce 8800 GT 512MB, and will be able to handle higher resolutions while still performing well. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 20032 (209%)

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 max amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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