GeForce GTS 250 1GB vs Radeon HD 6770 1GB
Intro
The GeForce GTS 250 1GB comes with a core clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit memory bus, and uses a 65/55 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon HD 6770 1GB, which comes with core speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 memory. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max 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
