GeForce 8500 GT vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which has a clock frequency of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also uses a 384-bit memory bus, and uses a 16 nm design. It is made up of 3584 SPUs, 224 TAUs, and 96 ROPs.

Texel Rate

The Nvidia Titan X will be quite a bit (about 8717%) more effective at texture filtering than the GeForce 8500 GT. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 313808 (8717%)

Pixel Rate

The Nvidia Titan X is quite a bit (about 7457%) faster with regards to full screen anti-aliasing than the GeForce 8500 GT, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 134232 (7457%)

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 information (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
