GeForce 8800 Ultra vs Radeon RX 460


Intro

The GeForce 8800 Ultra comes with a core clock speed of 612 MHz and a GDDR3 memory speed of 1080 MHz. It also uses a 384-bit bus, and makes use of a 90 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 24 Raster Operation Units.

Compare all that to the Radeon RX 460, which features a core clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

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 is 8% quicker than the GeForce 8800 Ultra in general, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 460 should be much (about 56%) faster with regards to 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

If running with lots of anti-aliasing 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
