GeForce GTX 465 vs GeForce GTX Titan

Intro

Compare those specs to the GeForce GTX Titan, which comes with core clock speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 memory. It features 2688 SPUs along with 224 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 465		200 Watts
GeForce GTX Titan		250 Watts
	Difference: 50 Watts (25%)

Memory Bandwidth

In theory, the GeForce GTX Titan should be 181% quicker than the GeForce GTX 465 overall, due to its greater bandwidth. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 185792 (181%)

Texel Rate

The GeForce GTX Titan is much (about 602%) better at texture filtering than the GeForce GTX 465. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 160780 (602%)

Pixel Rate

The GeForce GTX Titan should be quite a bit (more or less 107%) more effective at FSAA than the GeForce GTX 465, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 20752 (107%)

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 (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core 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 number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
