GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 970M

Intro

Compare those specs to the GeForce GTX 970M, which features a core clock speed of 924 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 192-bit bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 Texture Address Units, and 48 Raster Operation Units.

As far as performance goes, the GeForce GTX 970M should in theory be quite a bit better than the GeForce 9500 GT 512MB GDDR3 in general. (explain)

GeForce GTX 970M		96000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 70400 (275%)

Texel Rate

The GeForce GTX 970M is much (about 740%) more effective at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GTX 970M		73920 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 65120 (740%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970M is superior to the GeForce 9500 GT 512MB GDDR3, by far. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 39952 (908%)

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 megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
