GeForce GTX 465 vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1024 MHz. The GDDR5 memory runs at a speed of 1652 MHz on this model. It features 768 SPUs as well as 48 TAUs and 32 ROPs.

GeForce GTX 465		102592 MB/sec
	Difference: 3136 (3%)

Texel Rate

The GeForce GTX 950 should be quite a bit (approximately 84%) better at texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 22444 (84%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950 is superior to the GeForce GTX 465, by far. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 13344 (69%)

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 megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
