GeForce 9800 GT 1GB vs GeForce GTX 460 SE

Intro

The GeForce 9800 GT 1GB makes use of a 65/55 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 460 SE, which makes use of a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 RAM works at a frequency of 850 MHz on this specific model. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GT 1GB 105 Watts
GeForce GTX 460 SE 150 Watts
Difference: 45 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should perform quite a bit faster than the GeForce 9800 GT 1GB in general. (explain)

GeForce GTX 460 SE 108800 MB/sec
GeForce 9800 GT 1GB 57600 MB/sec
Difference: 51200 (89%)

Texel Rate

The GeForce 9800 GT 1GB should be a little bit (more or less 8%) faster with regards to anisotropic filtering than the GeForce GTX 460 SE. (explain)

GeForce 9800 GT 1GB 33600 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 2400 (8%)

Pixel Rate

The GeForce GTX 460 SE is a lot (more or less 117%) more effective at full screen anti-aliasing than the GeForce 9800 GT 1GB, and also should be capable of handling higher resolutions better. (explain)

GeForce GTX 460 SE 20800 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 11200 (117%)

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 megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
