GeForce 940M vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 940M has core speeds of 1072 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the GeForce 9500 GT 1GB GDDR3, which makes use of a 55 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 RAM is set to run at a speed of 800 MHz on this specific model. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9500 GT 1GB GDDR3 should be 60% quicker than the GeForce 940M in general, due to its greater data rate. (explain)

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

Texel Rate

The GeForce 940M is much (approximately 192%) more effective at texture filtering 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

If using a high screen resolution is important to you, then the GeForce 940M is superior to the GeForce 9500 GT 1GB GDDR3, by far. (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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
