GeForce GT 310 vs GeForce GTX 465

Intro

Compare those specifications to the GeForce GTX 465, which has GPU clock speed of 607 MHz, and 1024 MB of GDDR5 RAM running at 802 MHz through a 256-bit bus. It also is made up of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 310		16000 MB/sec
	Difference: 86592 (541%)

Texel Rate

The GeForce GTX 465 should be quite a bit (approximately 467%) better at AF than the GeForce GT 310. (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 21996 (467%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 465 is the winner, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 17068 (724%)

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 largest amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
