GeForce GT 340 1GB vs GeForce GTX 965M

Intro

The GeForce GT 340 1GB comes with a core clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Compare those specs to the GeForce GTX 965M, which has GPU clock speed of 944 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

GeForce GT 340 1GB 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The GeForce GTX 965M is a lot (approximately 243%) more effective at AF than the GeForce GT 340 1GB. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce GT 340 1GB 17600 Mtexels/sec
Difference: 42816 (243%)

Pixel Rate

The GeForce GTX 965M should be quite a bit (more or less 587%) more effective at AA than the GeForce GT 340 1GB, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce GT 340 1GB 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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
