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 set to run at 802 MHz through a 256-bit bus. It also features 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

The GeForce GTX 465 is a lot (more or less 467%) more effective 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

The GeForce GTX 465 should be a lot (more or less 724%) better at anti-aliasing than the GeForce GT 310, and will be capable of handling higher resolutions more effectively. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
