GeForce 8500 GT vs Nvidia Titan Xp

Intro

Compare that to the Nvidia Titan Xp, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1582 MHz. The GDDR5X RAM works at a frequency of 1426 MHz on this particular model. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8500 GT		45 Watts
Nvidia Titan Xp		250 Watts
	Difference: 205 Watts (456%)

Memory Bandwidth

Performance-wise, the Nvidia Titan Xp should theoretically be a lot better than the GeForce 8500 GT in general. (explain)

Nvidia Titan Xp		560845 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 548045 (4282%)

Texel Rate

The Nvidia Titan Xp should be quite a bit (about 10447%) more effective at anisotropic filtering than the GeForce 8500 GT. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 376080 (10447%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan Xp is superior to the GeForce 8500 GT, and very much so. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 150072 (8337%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
