GeForce 940M vs GeForce 9500 GT 1GB GDDR3

Intro

Compare all of that to the GeForce 9500 GT 1GB GDDR3, which uses a 55 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 RAM runs at a frequency of 800 MHz on this particular card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9500 GT 1GB GDDR3, in theory, should perform much faster than the GeForce 940M overall. (explain)

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

Texel Rate

The GeForce 940M will be a lot (more or less 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 will be much (about 95%) better at full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and 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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
