GeForce 9800 GTX+ vs GeForce GTX 950M

Intro

Compare all of that to the GeForce GTX 950M, which comes with GPU core speed of 914 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 90 Watts (164%)

Memory Bandwidth

Theoretically, the GeForce 9800 GTX+ should perform quite a bit faster than the GeForce GTX 950M overall. (explain)

GeForce 9800 GTX+		70400 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 38400 (120%)

Texel Rate

The GeForce 9800 GTX+ is much (approximately 29%) better at AF than the GeForce GTX 950M. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 10672 (29%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 950M is a better choice, and very much so. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 2816 (24%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
