It might be owed to component shortages or price-performance issues

AMD's Radeon HD 7990 dual-GPU graphics card should have been out by now, but things keep happening and causing the release to be pushed back.

Most recently, it has been suggested that Advanced Micro Devices won't be able to start selling the item this July after all.

This is reminiscent of how the dual-GPU adapter could not launch in June. Or April. Or even earlier in the first quarter of the year (2012).

There is a silver lining in all this though: we can breathe a sigh of relief knowing that the HD 7990 has not, in fact, been scrapped.

The cause behind this latest delay is vague, but it could be related to price-performance-watt problems, or a shortage of PEX8747 PCIe bridge chips by PLX (also used in NVIDIA's GeForce GTX 690).
