PCB Design

As we have already reported in our earlier articles, neither ATI Technologies, nor Nvidia Corp. allow their partners to tweak print circuit boards (PCBs) of their high-end graphics cards. Moreover, very few companies can actually afford this, as PCBs have become state-of-the-art technology nowadays and reworking them is not an easy task.

That said, the Toxic version of the Radeon X1900 XTX looks just the same as all the other Radeon X1900 XTX-based graphics cards on the market, except, of course, the cooling system.

Even the PCB revision 109-A51031-50 of the reference Radeon X1900 XTX board from ATI remained on the Sapphire Blizzard, hence, you should expect Blizzard to feature the same 136-pin BGA K4J52324QC-BJ11 memory chips from Samsung with 1.1ns access time and maximum clock-speed of 1800MHz.

It is interesting to note that the chip Sapphire uses on the Blizzard Radeon X1900 XTX was made on the 4th of week of this year, in late January, whereas our reference Radeon X1900 XTX board used graphics processor produced on the 45th week of 2005, in early November.

All in all, when it comes to PCB design, all the Radeon X1900 XTX graphics boards are just the same, even in terms of print circuit board colour. Maybe ATI should allow its partners to obtain PCBs with black or blue colour for their premium-class offerings?
