Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 6950
IntroThe GeForce 9600 GT 1GB features a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit bus, and uses a 65/55 nm design. It is comprised of 64 SPUs, 32 TAUs, and 16 ROPs.
Compare those specifications to the Radeon HD 6950, which makes use of a 40 nm design. ATi has set the core speed at 800 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this particular model. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6950 should perform much faster than the GeForce 9600 GT 1GB overall. (explain)
Texel RateThe Radeon HD 6950 is quite a bit (about 238%) faster with regards to AF than the GeForce 9600 GT 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6950 is superior to the GeForce 9600 GT 1GB, and very much so. (explain)
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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
