AMD's RV770LE powered HD 4830 part, has garnered a fair amount of press recently.

Just earlier today, we reported on the exciting performance expectations for AMD's latest HD 48xx series offering, leading belief that the SKU, will comfortably surpass NVIDIA's GeForce 9800GT solution.

Whilst it was initially claimed that the HD 4830 would feature 480 stream processing units, it is now believed that the RV770LE powered part will be endowed with 640 stream processing units instead.

Additionally, it is now claimed that October 21st is set to be launch date for the new addition to AMD's line-up and, an expected price-tag of under $150, will certainly fan those price to performance ratio flames.
