ATi has decided to go with 16pp R520 with their latest re-taped revision called A1023 so the launch of R520 on Oct 4th has only 16 pipelines for their top lineup X1800XT. We expect ATi to replace R520 quickly with R580 in early next year to better compete with NVIDIA’s lineup. The R520 Rev 2 card gotten by us is a golden sample in its early stage originally planned for 24/32pp but very poor yield push ATi to release 16pp R520 instead. Now this card is into Rev 5 and it could be meant for R580 instead. We also know that latest X1800XL core is known as AE revision.
