Hexus ponders what GPU would make a good Radeon HD 5770 from AMD?

An age-old method of reducing costs is to snip the memory-interface width. We'd bet on a 192-bit bus supplanting the 256-bit on the HD 58xx GPUs. Now we're at it, snipping the frame-buffer to 768MBs of GDDR5 doesn't sound like a bad idea, either. Putting ourselves in AMD's shoes, we'd keep this architecture and clock it in lower for the Radeon HD 5750, priced at around £115. If we're really nasty, we'd chop bandwidth to 128 bits, but that's probably the preserve of the Radeon HD 55xx GPU.
