GeForce GT 130 vs Radeon HD 6450 (OEM)

Intro

Compare all that to the Radeon HD 6450 (OEM), which features a clock frequency of 625 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It features 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Radeon HD 6450 (OEM)		31 Watts
GeForce GT 130		75 Watts
	Difference: 44 Watts (142%)

Memory Bandwidth

In theory, the Radeon HD 6450 (OEM) will be 7% faster than the GeForce GT 130 in general, because of its higher data rate. (explain)

Radeon HD 6450 (OEM)		12800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 800 (7%)

Texel Rate

The GeForce GT 130 will be quite a bit (more or less 140%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)

GeForce GT 130		12000 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 7000 (140%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 130 is superior to the Radeon HD 6450 (OEM), by far. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 5500 (220%)

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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core 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 maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
