Compare any two graphics cards:
GeForce GTX 970 vs Radeon HD 6770 1GB
IntroThe GeForce GTX 970 uses a 28 nm design. nVidia has clocked the core frequency at 1050 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this model. It features 1664 SPUs along with 104 Texture Address Units and 64 Rasterization Operator Units.Compare all of that to the Radeon HD 6770 1GB, which has GPU clock speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is comprised of 800 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970 should be a lot faster than the Radeon HD 6770 1GB overall. (explain)
Texel RateThe GeForce GTX 970 is much (approximately 203%) faster with regards to anisotropic filtering than the Radeon HD 6770 1GB. (explain)
Pixel RateThe GeForce GTX 970 should be much (about 367%) faster with regards to FSAA than the Radeon HD 6770 1GB, and also will be capable of handling higher resolutions without slowing down too much. (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 (measured 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 its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
