GeForce GTX 260 Core 216 vs GeForce GTX 960M

Intro

Compare those specs to the GeForce GTX 960M, which makes use of a 28 nm design. nVidia has clocked the core speed at 1096 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 2368 (6%)

Pixel Rate

The GeForce GTX 960M will be a little bit (approximately 9%) faster with regards to anti-aliasing than the GeForce GTX 260 Core 216, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 1408 (9%)

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 (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 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 the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
