GeForce GT 340 vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which uses a 28 nm design. nVidia has clocked the core frequency at 1096 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
GeForce GT 340		69 Watts
	Difference: 4 Watts (6%)

Memory Bandwidth

In theory, the GeForce GTX 960M should be 18% quicker than the GeForce GT 340 overall, due to its greater bandwidth. (explain)

GeForce GTX 960M		64000 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The GeForce GTX 960M is quite a bit (about 149%) faster with regards to AF than the GeForce GT 340. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 26240 (149%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 960M is a better choice, and very much so. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 13136 (299%)

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 MB per second) that can be transported across 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 type RAM, the result should be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
