GeForce 8600 GT 256MB GDDR3 vs Nvidia Titan Xp

Intro

Compare those specs to the Nvidia Titan Xp, which features GPU core speed of 1582 MHz, and 12288 MB of GDDR5X RAM set to run at 1426 MHz through a 384-bit bus. It also is comprised of 3840 Stream Processors, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 256MB GDDR3		47 Watts
Nvidia Titan Xp		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan Xp will be 2404% faster than the GeForce 8600 GT 256MB GDDR3 in general, because of its higher bandwidth. (explain)

Nvidia Titan Xp		560845 MB/sec
GeForce 8600 GT 256MB GDDR3		22400 MB/sec
	Difference: 538445 (2404%)

Texel Rate

The Nvidia Titan Xp should be quite a bit (more or less 4294%) more effective at anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
GeForce 8600 GT 256MB GDDR3		8640 Mtexels/sec
	Difference: 371040 (4294%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan Xp is a better choice, and very much so. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
GeForce 8600 GT 256MB GDDR3		4320 Mpixels/sec
	Difference: 147552 (3416%)

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 data (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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