GeForce GTX 465 vs GeForce GTX 960

Intro

Compare those specs to the GeForce GTX 960, which has a clock speed of 1127 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 465		102592 MB/sec
	Difference: 9408 (9%)

Texel Rate

The GeForce GTX 960 should be a lot (about 170%) faster with regards to texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 45420 (170%)

Pixel Rate

The GeForce GTX 960 is much (approximately 86%) more effective at FSAA than the GeForce GTX 465, and also will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 16640 (86%)

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 max amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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.
