GeForce GT 310 vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which features core speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
GeForce GTX 750		55 Watts
	Difference: 24 Watts (77%)

Memory Bandwidth

Performance-wise, the GeForce GTX 750 should in theory be a lot better than the GeForce GT 310 overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 64000 (400%)

Texel Rate

The GeForce GTX 750 should be quite a bit (about 593%) more effective at texture filtering than the GeForce GT 310. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 27928 (593%)

Pixel Rate

The GeForce GTX 750 will be quite a bit (approximately 593%) more effective at AA than the GeForce GT 310, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 13964 (593%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
