Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 6770 1GB
IntroThe GeForce GTS 250 1GB features 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 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon HD 6770 1GB, which has a GPU core clock speed of 900 MHz, and 1024 MB of GDDR5 RAM set to run at 1050 MHz through a 128-bit bus. It also is comprised of 800 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 250 1GB, in theory, should be a bit faster than the Radeon HD 6770 1GB overall. (explain)
Texel RateThe GeForce GTS 250 1GB should be quite a bit (approximately 31%) better at anisotropic filtering than the Radeon HD 6770 1GB. (explain)
Pixel RateThe Radeon HD 6770 1GB will be much (about 22%) more effective at FSAA than the GeForce GTS 250 1GB, and should be capable of handling higher resolutions better. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the memory 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
