Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 6770 1GB
IntroThe GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM works at a speed of 1100 MHz on this specific model. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 6770 1GB, which comes with a clock frequency of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is comprised of 800 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 250 1GB should theoretically perform a little bit faster than the Radeon HD 6770 1GB overall. (explain)
Texel RateThe GeForce GTS 250 1GB should be quite a bit (more or less 31%) better at anisotropic filtering than the Radeon HD 6770 1GB. (explain)
Pixel RateThe Radeon HD 6770 1GB will be quite a bit (approximately 22%) more effective at anti-aliasing than the GeForce GTS 250 1GB, and will be capable of handling higher resolutions more effectively. (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 largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out 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 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 most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

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
