http://www.techpowerup.com/167713/AMD-F ... 7990-.htmlAt the AMD Fusion Developer Summit (AFDS) 2012, the host unveiled its next flagship professional graphics card, the FirePro W9000. What makes the card particularly interesting is that it is dual-GPU, packing two Tahiti-derived GPUs, the same chips that go into making Radeon HD 7900 series. The FirePro W9000, is what many believe to be a professional variant of the Radeon HD 7990 "New Zealand" dual-GPU graphics card, which is facing delays for reasons unknown (actually, here's a possible reason).
The W9000 packs a total of 6 GB of GDDR5 memory, up to 264.8 million pixels/s; 4 TFLOPs single-precision and 1 TFLOPs double-precision floating-point performance. The card design does away with lateral-flow cooler, and uses a triple-fan heatsink assembly that packs three 90 mm low-speed (low-noise) fans. A surprise here, is that the card draws power from [just] two 8-pin PCIe power connectors (it's probably using two low-voltage Tahiti chips). It's an established fact that FirePro products are merely variations of Radeon products with possibly higher build quality, and an expanded software feature-set.
Et les annonces parlent ainsi d'un Tahiti XT2, cadencé à 1100Mhz mais n'utilisant que 1,020V par rapport aux 1,175V pour les 925Mhz actuels.
Après une 7970 qui a essuyé la première les plâtres du 28nm, on trouve une seconde version, plus puissante et moins énergivore qui va sortir, bénéficiant du travail de maçon du processus de gravure !
