Forgive my ignorance (which is why I'm in this thread asking about this): The web site specs don't list "memory frequency"; the "Effective Memory Clock Speed" and the "RAMDAC Speed" are 873 MHz, and the "Core Clock Speed" is 750 MHz.
"Effective Memory Clock Speed" = 873 MHz: That's it
You should look up the prices for a HD 5570, if it's the same or slighly more you should probably go for that one.
