GeForce 8800 Ultra vs GeForce GTX 260 Core 216

Intro

The GeForce 8800 Ultra features a GPU core clock speed of 612 MHz, and the 768 MB of GDDR3 RAM is set to run at 1080 MHz through a 384-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 24 ROPs.

Compare those specifications to the GeForce GTX 260 Core 216, which makes use of a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM works at a frequency of 999 MHz on this card. It features 216 SPUs along with 72 TAUs and 28 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 Ultra 171 Watts
GeForce GTX 260 Core 216 202 Watts
Difference: 31 Watts (18%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 260 Core 216 should theoretically be just a bit better than the GeForce 8800 Ultra overall. (explain)

GeForce GTX 260 Core 216 111888 MB/sec
GeForce 8800 Ultra 103680 MB/sec
Difference: 8208 (8%)

Texel Rate

The GeForce GTX 260 Core 216 will be a bit (approximately 6%) faster with regards to anisotropic filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 260 Core 216 41472 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 2304 (6%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 260 Core 216 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 260 Core 216 16128 Mpixels/sec
GeForce 8800 Ultra 14688 Mpixels/sec
Difference: 1440 (10%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred 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 RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
