GeForce GT 310 vs GeForce GTX 980

Intro

Compare those specifications to the GeForce GTX 980, which features core clock speeds of 1126 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
GeForce GTX 980		165 Watts
	Difference: 134 Watts (432%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 980 should in theory be much superior to the GeForce GT 310 in general. (explain)

GeForce GTX 980		224000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 208000 (1300%)

Texel Rate

The GeForce GTX 980 is a lot (more or less 2959%) faster with regards to anisotropic filtering than the GeForce GT 310. (explain)

GeForce GTX 980		144128 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 139416 (2959%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 980 is a better choice, by far. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 69708 (2959%)

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 data (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
