GeForce 8800 Ultra vs Radeon RX 460

Intro

Compare all that to the Radeon RX 460, which comes with a core clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It features 896 SPUs, 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

As far as performance goes, the Radeon RX 460 should theoretically be a little bit superior to 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 should be a lot (approximately 56%) more effective at AF than the GeForce 8800 Ultra. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 460 is superior to the GeForce 8800 Ultra, but not by far. (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 megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
