GeForce 9800 GTX vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which uses a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 memory runs at a speed of 1001 MHz on this specific model. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

GeForce 9800 GTX		140 Watts
GeForce GTX 560		150 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

In theory, the GeForce GTX 560 should be much faster than the GeForce 9800 GTX overall. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 9800 GTX		70400 MB/sec
	Difference: 57728 (82%)

Texel Rate

The GeForce GTX 560 will be a bit (more or less 5%) faster with regards to anisotropic filtering than the GeForce 9800 GTX. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 9800 GTX		43200 Mtexels/sec
	Difference: 2160 (5%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 is a better choice, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 15120 (140%)

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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
