GeForce GT 340 vs GeForce GTX 960M

Intro

The GeForce GT 340 comes with core clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 memory. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Compare all of that to the GeForce GTX 960M, which makes use of a 28 nm design. nVidia has set the core frequency at 1096 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

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 perform a small bit faster than the GeForce GT 340 overall. (explain)

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

Texel Rate

The GeForce GTX 960M should be a lot (about 149%) more effective at anisotropic filtering 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 high levels of AA is important to you, then the GeForce GTX 960M is a better choice, by a large margin. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
