GeForce 9800 GX2 vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which features core clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X RAM. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GX2		197 Watts
Nvidia Titan X		250 Watts
	Difference: 53 Watts (27%)

Memory Bandwidth

Theoretically, the Nvidia Titan X should perform much faster than the GeForce 9800 GX2 in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce 9800 GX2		128000 MB/sec
	Difference: 363520 (284%)

Texel Rate

The Nvidia Titan X should be quite a bit (more or less 313%) more effective at AF than the GeForce 9800 GX2. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce 9800 GX2		76800 Mtexels/sec
	Difference: 240608 (313%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is a better choice, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce 9800 GX2		19200 Mpixels/sec
	Difference: 116832 (609%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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