A little over a year after launching the last Radeon Pro Duo graphics card, AMD is back with an all-new version that has the same name but makes a whole bunch of changes. The new Radeon Pro Duo mashes two separate 14nm Polaris GPUs with 2,304 stream processors, 128 texture units, 32 ROPs, and 16GB of graphics RAM apiece (for a total of 32GB) into a single card. As the name implies, the card is being aimed primarily at professional users rather than gamers. It's based on the Radeon Pro WX 7100 workstation GPU, which uses one GPU with most of the same specs as the Radeon Pro Duo but with 8GB of RAM instead of 16GB.

You can find the full spec list for the card here, which will launch at "the end of May" for $999.

The card is quite different from last year's Radeon Pro Duo—that card launched at $1,499 and featured a pair of 28nm Fiji GPUs with 4,096 stream processors and 4GB of RAM each; it was also a power-hungry monster, requiring its own closed-loop liquid cooler, three external PCIe power plugs, and as much as 350W of power. The new card only needs two power plugs, uses an air blower typical of most GPUs, and has a rated TBP (typical board power) of 250W.

The end result is a card that has less processing power—AMD claims to offer 11.45 teraflops of performance compared to 16 for the older Radeon Pro—but one that is also substantially cheaper, cooler, and less power hungry, and you get dramatically more RAM to boot.

Dual-GPU cards are admittedly niche products, but they're useful as a way to get two GPUs into a computer with a single slot (or four GPUs into a machine with two slots if you don't mind the diminishing returns). AMD releases dual-GPU cards with some regularity; the Radeon R9 295X2 came out in 2014 and the Fiji-based Radeon Pro came out a little over a year ago. Nvidia has dabbled in this space, too, but it hasn't released a dual-GPU card since the GeForce GTX Titan Z in early 2014. Recent Titan cards like the just-announced Titan Xp have focused on offering larger individual GPUs with wide memory buses.
