GeForce 8800 Ultra vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which features GPU core speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 96 Watts (128%)

Memory Bandwidth

In theory, the Radeon RX 460 should perform a bit faster than the GeForce 8800 Ultra in general. (explain)

Radeon RX 460		112000 MB/sec
GeForce 8800 Ultra		103680 MB/sec
	Difference: 8320 (8%)

Texel Rate

The Radeon RX 460 is quite a bit (approximately 56%) more effective at anisotropic filtering than the GeForce 8800 Ultra. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 21872 (56%)

Pixel Rate

The Radeon RX 460 should be a bit (about 19%) better at anti-aliasing than the GeForce 8800 Ultra, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 2752 (19%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
