GeForce 9500 GT DDR2 vs GeForce GTX 965M

Intro

Compare that to the GeForce GTX 965M, which comes with GPU clock speed of 944 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 1024 SPUs, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 965M		60 Watts
	Difference: 10 Watts (20%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 965M should in theory be a lot superior to the GeForce 9500 GT DDR2 overall. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The GeForce GTX 965M will be much (about 587%) more effective at AF than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 51616 (587%)

Pixel Rate

The GeForce GTX 965M should be quite a bit (approximately 587%) faster with regards to AA than the GeForce 9500 GT DDR2, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 25808 (587%)

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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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 - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
