GeForce 8500 GT vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which features core speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8500 GT		45 Watts
GeForce GTX 750		55 Watts
	Difference: 10 Watts (22%)

Memory Bandwidth

In theory, the GeForce GTX 750 should be 525% quicker than the GeForce 8500 GT overall, due to its higher data rate. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 67200 (525%)

Texel Rate

The GeForce GTX 750 is quite a bit (about 807%) faster with regards to texture filtering than the GeForce 8500 GT. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 29040 (807%)

Pixel Rate

The GeForce GTX 750 is a lot (more or less 807%) better at AA than the GeForce 8500 GT, and also will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 14520 (807%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
