GeForce GT 230 vs Radeon HD 6450 (OEM)

Intro

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

Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 25600 (200%)

Texel Rate

The GeForce GT 230 should be much (about 76%) faster with regards to AF than the Radeon HD 6450 (OEM). (explain)

GeForce GT 230		8800 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 3800 (76%)

Pixel Rate

The GeForce GT 230 will be quite a bit (approximately 76%) more effective at FSAA than the Radeon HD 6450 (OEM), and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GT 230		4400 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 1900 (76%)

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 information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
