GeForce GT 310 vs Radeon HD 7750

Intro

Compare that to the Radeon HD 7750, which has GPU clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
Radeon HD 7750		55 Watts
	Difference: 24 Watts (77%)

Memory Bandwidth

As far as performance goes, the Radeon HD 7750 should in theory be quite a bit superior to the GeForce GT 310 in general. (explain)

Radeon HD 7750		72000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon HD 7750 will be a lot (more or less 443%) more effective at AF than the GeForce GT 310. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 20888 (443%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 7750 is superior to the GeForce GT 310, by far. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 10444 (443%)

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 information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
