GeForce 8800 GT 1GB vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which comes with core clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
Radeon RX 470		120 Watts
	Difference: 15 Watts (14%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 will be 267% faster than the GeForce 8800 GT 1GB in general, because of its greater data rate. (explain)

Radeon RX 470		211200 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 153600 (267%)

Texel Rate

The Radeon RX 470 should be a lot (more or less 253%) faster with regards to texture filtering than the GeForce 8800 GT 1GB. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 84928 (253%)

Pixel Rate

The Radeon RX 470 should be quite a bit (about 209%) faster with regards to FSAA than the GeForce 8800 GT 1GB, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce 8800 GT 1GB		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: Bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
