GeForce GT 230 vs Radeon HD 6750 1GB

Intro

Compare all of that to the Radeon HD 6750 1GB, which comes with a clock frequency of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 720 SPUs, 36 TAUs, and 16 ROPs.

GeForce GT 230		65 Watts
Radeon HD 6750 1GB		86 Watts
	Difference: 21 Watts (32%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 1GB should be much faster than the GeForce GT 230 in general. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The Radeon HD 6750 1GB will be a lot (approximately 197%) better at texture filtering than the GeForce GT 230. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 17300 (197%)

Pixel Rate

The Radeon HD 6750 1GB should be quite a bit (more or less 164%) better at anti-aliasing than the GeForce GT 230, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 7200 (164%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus 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 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 can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
