VS

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

Intro

The GeForce 9600 GT 512MB has a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and uses a 65/55 nm design. It is made up of 64 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon HD 6670 (OEM) 1GB, which makes use of a 40 nm design. ATi has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular card. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
