Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 6770 1GB
IntroThe GeForce GTS 250 1GB has core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6770 1GB, which features GPU clock speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is made up of 800 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTS 250 1GB should perform a bit faster than the Radeon HD 6770 1GB overall. (explain)
Texel RateThe GeForce GTS 250 1GB is quite a bit (about 31%) faster with regards to texture filtering than the Radeon HD 6770 1GB. (explain)
Pixel RateThe Radeon HD 6770 1GB will be quite a bit (approximately 22%) faster with regards to AA than the GeForce GTS 250 1GB, and also should be capable of handling higher screen 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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 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 AA, High Dynamic Range 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 is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 maximum fill rate.

Comments
One Response to “GeForce GTS 250 1GB vs Radeon HD 6770 1GB”this comparison is false, because the HD 6770 has a bandwidth greater than the old GTS 250, the HD 6670 is not 67.200mb/sec, has 76.8 Gb / s, and the GTS 250 loses to the HD 6770, the GTS 250 more could be compared to the HD 6750 or less
