GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this model. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Texel Rate

The GeForce GTX 650 Ti will be much (more or less 575%) faster with regards to anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 50592 (575%)

Pixel Rate

The GeForce GTX 650 Ti is a lot (more or less 237%) more effective at AA than the GeForce 9500 GT DDR2, and should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 10448 (237%)

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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
