GeForce GT 230 vs GeForce GTX 950M

Intro

Compare those specs to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has set the core speed at 914 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the GeForce GT 230 should in theory be just a bit better than the GeForce GTX 950M overall. (explain)

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

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 315%) more effective at AF than the GeForce GT 230. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950M is the winner, by far. (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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 texture units by the core clock speed of the chip. The higher the texel rate, 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 most pixels the graphics card could 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 Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
