GeForce GT 240 GDDR5 vs GeForce GTX 860M

Intro

The GeForce GT 240 GDDR5 features a GPU core speed of 550 MHz, and the 512 MB of GDDR5 memory runs at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 TAUs, and 8 ROPs.

Compare those specifications to the GeForce GTX 860M, which comes with a clock frequency of 797 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 1152 SPUs, 96 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M 45 Watts
GeForce GT 240 GDDR5 70 Watts
Difference: 25 Watts (56%)

Memory Bandwidth

Theoretically, the GeForce GTX 860M should perform just a bit faster than the GeForce GT 240 GDDR5 overall. (explain)

GeForce GTX 860M 64000 MB/sec
GeForce GT 240 GDDR5 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The GeForce GTX 860M is much (approximately 335%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 860M 76512 Mtexels/sec
GeForce GT 240 GDDR5 17600 Mtexels/sec
Difference: 58912 (335%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 860M is a better choice, by far. (explain)

GeForce GTX 860M 12752 Mpixels/sec
GeForce GT 240 GDDR5 4400 Mpixels/sec
Difference: 8352 (190%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
