GeForce 9600 GT 512MB vs Radeon HD 6670 (OEM) 1GB


Intro

The GeForce 9600 GT 512MB makes use of a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 memory runs at a speed of 900 MHz on this specific card. It features 64 SPUs as well as 32 TAUs and 16 ROPs.

Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which has a clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
