GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti

Intro

Compare that to the GeForce GTX 650 Ti, which has core speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti should perform much faster than the GeForce 9500 GT DDR2 overall. (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 should be much (approximately 575%) more effective at 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 quite a bit (about 237%) better at FSAA than the GeForce 9500 GT DDR2, and should be able to handle higher screen resolutions while still performing well. (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 (in units of MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
