GeForce 8800 Ultra vs GeForce GTX 260

Intro

The GeForce 8800 Ultra has a GPU core 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 made up of 128 SPUs, 64 TAUs, and 24 ROPs.

Compare those specifications to the GeForce GTX 260, which makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM runs at a speed of 999 MHz on this particular model. It features 192 SPUs along with 64 TAUs and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 Ultra 171 Watts
GeForce GTX 260 182 Watts
Difference: 11 Watts (6%)

Memory Bandwidth

In theory, the GeForce GTX 260 should perform a small bit faster than the GeForce 8800 Ultra overall. (explain)

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

Texel Rate

The GeForce 8800 Ultra should be a small bit (more or less 6%) faster with regards to AF than the GeForce GTX 260. (explain)

GeForce 8800 Ultra 39168 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 2304 (6%)

Pixel Rate

The GeForce GTX 260 is just a bit (approximately 10%) more effective at anti-aliasing than the GeForce 8800 Ultra, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 260 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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, 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 maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
