Compare any two graphics cards:
Radeon HD 5770 vs Radeon HD 6870
IntroThe Radeon HD 5770 uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.Compare all of that to the Radeon HD 6870, which features a GPU core clock speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 256-bit bus. It also features 1120 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6870 should theoretically be a lot better than the Radeon HD 5770 overall. (explain)
Texel RateThe Radeon HD 6870 will be quite a bit (approximately 48%) better at anisotropic filtering than the Radeon HD 5770. (explain)
Pixel RateThe Radeon HD 6870 is quite a bit (about 112%) better at anti-aliasing than the Radeon HD 5770, and also will be able to handle higher screen 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 information (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

i made the change from a sapphire 5770 toxic to another sapphire 6870... it was def worth the change... i played dead rising 2 on both cards... the 5770 could only handle trilinear and med zombies and low shadows... the 6870 does it easily on 4x af and everything else on high... the 6870 does very well even with shadows and everything.
the hd 5770 is more comparable to the 6770 or 6790, the because of this the performance boost is huge, the HD 6870 is 112% more powerful
