GeForce 8800 GT 512MB vs Radeon RX 480

Intro

Compare those specifications to the Radeon RX 480, which uses a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this card. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB		105 Watts
Radeon RX 480		150 Watts
	Difference: 45 Watts (43%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 480 should be 355% quicker than the GeForce 8800 GT 512MB overall, due to its higher data rate. (explain)

Radeon RX 480		262144 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 204544 (355%)

Texel Rate

The Radeon RX 480 will be a lot (approximately 380%) faster with regards to texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 127680 (380%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 480 is a better choice, by a large margin. (explain)

Radeon RX 480		35840 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 26240 (273%)

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 information (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 reach the max fill rate.
