GeForce GT 230 vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which uses a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon HD 6750 should be much faster than the GeForce GT 230 overall. (explain)

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

Texel Rate

The Radeon HD 6750 will be quite a bit (more or less 197%) faster with regards to AF than the GeForce GT 230. (explain)

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

Pixel Rate

The Radeon HD 6750 is quite a bit (about 164%) more effective at FSAA than the GeForce GT 230, and also should be capable of handling higher resolutions better. (explain)

Radeon HD 6750		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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
