GeForce GTX 650 Ti 2GB vs GeForce GTX 960M

Intro

Compare those specs to the GeForce GTX 960M, which uses a 28 nm design. nVidia has clocked the core speed at 1096 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 45 Watts (69%)

Memory Bandwidth

Performance-wise, the GeForce GTX 650 Ti 2GB should theoretically be much superior to the GeForce GTX 960M in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 22400 (35%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be a lot (approximately 35%) better at anisotropic filtering than the GeForce GTX 960M. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GTX 960M		43840 Mtexels/sec
	Difference: 15552 (35%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 960M is superior to the GeForce GTX 650 Ti 2GB, but it probably won't make a huge difference. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 2688 (18%)

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 information (counted in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
