GeForce 8500 GT vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which has a GPU core clock speed of 928 MHz, and 1024 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8500 GT		45 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 65 Watts (144%)

Memory Bandwidth

In theory, the GeForce GTX 650 Ti should be much faster than the GeForce 8500 GT overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 73600 (575%)

Texel Rate

The GeForce GTX 650 Ti should be a lot (about 1550%) better at AF than the GeForce 8500 GT. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 55792 (1550%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 650 Ti is superior to the GeForce 8500 GT, and very much so. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 13048 (725%)

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 data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
