GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti

Intro

Compare those specifications to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 RAM works at a frequency of 1350 MHz on this specific card. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 60 Watts (120%)

Memory Bandwidth

Performance-wise, the GeForce GTX 650 Ti should in theory be much superior to the GeForce 9500 GT DDR2 in general. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 70400 (440%)

Texel Rate

The GeForce GTX 650 Ti is much (about 575%) better at AF 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is a better choice, by a large margin. (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 max amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
