GeForce 9800 GTX+ vs GeForce GTX 460

Intro

Compare those specifications to the GeForce GTX 460, which comes with GPU core speed of 675 MHz, and 768 MB of GDDR5 RAM running at 900 MHz through a 192-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GTX+		145 Watts
GeForce GTX 460		150 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

In theory, the GeForce GTX 460 is 23% quicker than the GeForce 9800 GTX+ overall, because of its greater data rate. (explain)

GeForce GTX 460		86400 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 16000 (23%)

Texel Rate

The GeForce 9800 GTX+ should be quite a bit (approximately 25%) more effective at anisotropic filtering than the GeForce GTX 460. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 9432 (25%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 is a better choice, and very much so. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 4392 (37%)

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: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 can be processed per second. This is calculated 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
