GeForce 9800 GTX vs GeForce GTX 465

Intro

Compare those specs to the GeForce GTX 465, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM works at a frequency of 802 MHz on this specific model. It features 352 SPUs as well as 44 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GTX		140 Watts
GeForce GTX 465		200 Watts
	Difference: 60 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 is 46% faster than the GeForce 9800 GTX in general, because of its higher bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
GeForce 9800 GTX		70400 MB/sec
	Difference: 32192 (46%)

Texel Rate

The GeForce 9800 GTX is a lot (more or less 62%) better at texture filtering than the GeForce GTX 465. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 16492 (62%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 465 is a better choice, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 8624 (80%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
