GeForce GT 230 vs GeForce GTX 950M

Intro

Compare all of that to the GeForce GTX 950M, which comes with a core clock frequency of 914 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

GeForce GTX 950M		55 Watts
GeForce GT 230		65 Watts
	Difference: 10 Watts (18%)

Memory Bandwidth

As far as performance goes, the GeForce GT 230 should in theory be just a bit superior to the GeForce GTX 950M in general. (explain)

GeForce GT 230		38400 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The GeForce GTX 950M should be much (approximately 315%) faster with regards to texture filtering than the GeForce GT 230. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 27760 (315%)

Pixel Rate

The GeForce GTX 950M will be much (more or less 232%) faster with regards to full screen anti-aliasing than the GeForce GT 230, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 10224 (232%)

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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 applied in one second. This number is worked out 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 graphics card will be at 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 one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
