DigiTimes is reporting that ATi's upcoming chip release will come in the middle of 3Q (August?). This estimate is based on capability to ship volume.

"ATI Technologies expects to begin volume shipments of its 90nm graphics processing units (GPUs), the R520, R530 and RV515, in the middle of the third quarter, as unspecified issues for manufacturing on 90nm technology will soon be solved, according to ATI Taiwan. ATI also plans to introduce another flagship chip, the R580, in early 2006."
