GeForce 940M vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 940M makes use of a 28 nm design. nVidia has clocked the core frequency at 1072 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Compare those specifications to the GeForce 9500 GT 1GB GDDR3, which has a core clock speed of 550 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9500 GT 1GB GDDR3 is 60% faster than the GeForce 940M in general, due to its greater bandwidth. (explain)

GeForce 9500 GT 1GB GDDR3 25600 MB/sec
GeForce 940M 16000 MB/sec
Difference: 9600 (60%)

Texel Rate

The GeForce 940M is much (about 192%) faster with regards to AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 940M 25728 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 16928 (192%)

Pixel Rate

The GeForce 940M is a lot (approximately 95%) faster with regards to AA than the GeForce 9500 GT 1GB GDDR3, and also should be capable of handling higher resolutions better. (explain)

GeForce 940M 8576 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 4176 (95%)

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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
