Compare any two graphics cards:
GeForce GT 340 vs Radeon HD 6670 (OEM)
IntroThe GeForce GT 340 makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this particular card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6670 (OEM), which has a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6670 (OEM) should theoretically be a small bit faster than the GeForce GT 340 overall. (explain)
Texel RateThe Radeon HD 6670 (OEM) is a little bit (approximately 9%) faster with regards to anisotropic filtering than the GeForce GT 340. (explain)
Pixel RateThe Radeon HD 6670 (OEM) should be quite a bit (more or less 45%) faster with regards to AA than the GeForce GT 340, and will be able to handle higher resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
