Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 6870
IntroThe GeForce 9600 GT 512MB comes with a GPU clock speed of 650 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also features 64 Stream Processors, 32 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 6870, which makes use of a 40 nm design. ATi has set the core frequency at 900 MHz. The GDDR5 memory is set to run at a speed of 1050 MHz on this model. It features 1120 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6870 is 133% quicker than the GeForce 9600 GT 512MB overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 6870 is much (about 142%) better at AF than the GeForce 9600 GT 512MB. (explain)
Pixel RateThe Radeon HD 6870 will be quite a bit (more or less 177%) more effective at anti-aliasing than the GeForce 9600 GT 512MB, and also able to handle higher resolutions while still performing well. (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.
Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If 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, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
