ATI Radeon HD 4750 to take on Geforce 9800 GT
 

Simply put, the RV770LE is a toned down variant of the RV770 core that will position below the RV770 Pro (Radeon HD 4850). It features lower clock speeds than the RV770 Pro and more importantly, a 192 bit memory bus and 480 Stream Processors. This also affects the TMU and ROP counts with the new core having 12 ROPs and 24 TMUs. Memory configurations would be affected as well. While some sources indicate that it would be branded as Radeon HD 4830, others say it's likely to be branded as the Radeon HD 4750 and is slated for release in October.
