GeForce 9800 GTX+ vs GeForce GTX 570

Intro

The GeForce 9800 GTX+ has core speeds of 738 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare all of that to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 memory works at a frequency of 950 MHz on this specific model. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GTX+ 145 Watts
GeForce GTX 570 219 Watts
Difference: 74 Watts (51%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 should perform quite a bit faster than the GeForce 9800 GTX+ overall. (explain)

GeForce GTX 570 152000 MB/sec
GeForce 9800 GTX+ 70400 MB/sec
Difference: 81600 (116%)

Texel Rate

The GeForce 9800 GTX+ will be just a bit (approximately 8%) faster with regards to anisotropic filtering than the GeForce GTX 570. (explain)

GeForce 9800 GTX+ 47232 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 3312 (8%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 570 is the winner, and very much so. (explain)

GeForce GTX 570 29280 Mpixels/sec
GeForce 9800 GTX+ 11808 Mpixels/sec
Difference: 17472 (148%)

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 max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
