GeForce GT 340 vs GeForce GTX 960M

Intro

The GeForce GT 340 features a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 32 Texture Address Units, and 8 ROPs.

Compare those specifications to the GeForce GTX 960M, which has clock speeds of 1096 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs 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

Theoretically speaking, the GeForce GTX 960M will be 18% quicker than the GeForce GT 340 overall, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 960M should be much (more or less 149%) better at 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 using high levels of AA 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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
