Compare any two graphics cards:
GeForce 9500 GT DDR2 vs Radeon HD 6670 (OEM)
IntroThe GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has set the core speed at 550 MHz. The DDR2 memory runs at a frequency of 500 MHz on this particular card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6670 (OEM), which comes with GPU core speed of 800 MHz, and 512 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 6670 (OEM) should perform much faster than the GeForce 9500 GT DDR2 in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) should be quite a bit (about 118%) more effective at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe Radeon HD 6670 (OEM) should be quite a bit (about 45%) faster with regards to AA than the GeForce 9500 GT DDR2, and should be able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at 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 could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
