GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 970M

Intro

The GeForce 9500 GT 1GB GDDR3 has a GPU core speed of 550 MHz, and the 1024 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 ROPs.

Compare those specifications to the GeForce GTX 970M, which uses a 28 nm design. nVidia has clocked the core frequency at 924 MHz. The GDDR5 memory works at a speed of 1000 MHz on this card. It features 1280 SPUs along with 80 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3 50 Watts
GeForce GTX 970M 75 Watts
Difference: 25 Watts (50%)

Memory Bandwidth

Theoretically, the GeForce GTX 970M should perform quite a bit faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

GeForce GTX 970M 96000 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 70400 (275%)

Texel Rate

The GeForce GTX 970M should be much (approximately 740%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 970M 73920 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 65120 (740%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 970M is a better choice, and very much so. (explain)

GeForce GTX 970M 44352 Mpixels/sec
GeForce 9500 GT 1GB 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
