GeForce GT 340 vs GeForce GTX 965M

Intro

The GeForce GT 340 has core clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 RAM. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 965M, which makes use of a 28 nm design. nVidia has set the core speed at 944 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this card. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Consumption (Max TDP)

GeForce GTX 965M 60 Watts
GeForce GT 340 69 Watts
Difference: 9 Watts (15%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 965M should be 18% quicker than the GeForce GT 340 overall, due to its greater data rate. (explain)

GeForce GTX 965M 64000 MB/sec
GeForce GT 340 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The GeForce GTX 965M will be a lot (more or less 243%) more effective at AF than the GeForce GT 340. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce GT 340 17600 Mtexels/sec
Difference: 42816 (243%)

Pixel Rate

The GeForce GTX 965M should be a lot (approximately 587%) better at FSAA than the GeForce GT 340, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce GT 340 4400 Mpixels/sec
Difference: 25808 (587%)

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 information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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