GeForce 9600 GT 512MB vs Radeon HD 4830 1GB
Intro
The GeForce 9600 GT 512MB features a core clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit memory bus, and makes use of a 65/55 nm design. It features 64 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon HD 4830 1GB, which makes use of a 55 nm design. AMD has clocked the core speed at 575 MHz. The GDDR4 memory is set to run at a speed of 900 MHz on this particular model. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same memory bandwidth, so in theory they should perform exactly the same. (explain)
Texel Rate
The GeForce 9600 GT 512MB should be just a bit (more or less 13%) faster with regards to AF than the Radeon HD 4830 1GB. (explain)| GeForce 9600 GT 512MB |

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
