GeForce GTX 750 vs Radeon HD 3470 512MB

Intro

Compare all of that to the Radeon HD 3470 512MB, which uses a 55 nm design. AMD has set the core frequency at 800 MHz. The GDDR3 RAM works at a frequency of 950 MHz on this model. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 750 is 163% faster than the Radeon HD 3470 512MB in general, due to its greater bandwidth. (explain)

GeForce GTX 750		80000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 49600 (163%)

Texel Rate

The GeForce GTX 750 will be a lot (about 920%) faster with regards to texture filtering than the Radeon HD 3470 512MB. (explain)

GeForce GTX 750		32640 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 29440 (920%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 750 is the winner, by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 13120 (410%)

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 max amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
