GeForce GTX 295 vs GeForce GTX 965M

Intro

Compare those specifications to the GeForce GTX 965M, which features clock speeds of 944 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M		60 Watts
GeForce GTX 295		289 Watts
	Difference: 229 Watts (382%)

Memory Bandwidth

The GeForce GTX 295 should in theory perform a lot faster than the GeForce GTX 965M overall. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 159776 (250%)

Texel Rate

The GeForce GTX 295 is quite a bit (more or less 53%) more effective at texture filtering than the GeForce GTX 965M. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 965M		60416 Mtexels/sec
	Difference: 31744 (53%)

Pixel Rate

The GeForce GTX 295 will be just a bit (more or less 7%) better at anti-aliasing than the GeForce GTX 965M, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 965M		30208 Mpixels/sec
	Difference: 2048 (7%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed 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 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 maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
