Some early reports indicated that both the HD 5750 and the HD 5770 featured an identical memory clock, and as we suspected, they were wrong. The memory on HD 5750 cards is clocked at 1150MHz, and on HD 5770 cards it's 50MHz faster. Not really a major difference, but still worth noting. The HD 5750 will also be offered in 512MB version, but it seems the launch version will all feature 1024MB of GDDR5 memory.
