AMD Radeon HD 7990 Dual-GPU Card Coming Q1 2012

Subject: Graphics Cards | December 26, 2011 - 09:05 AM |
Tagged: tahiti, southern islands, radeon, amd, 7990, 7970

The big talk during the holiday break was AMD's release of the Radeon HD 7970 3GB graphics card - the new single-GPU performance leader.  I gave the card our Editor's Choice award for simply impressing the hell out of us, all while keeping power consumption in check thanks to the TSMC 28nm process technology it is built on.  Being the first card to support the upcoming DX11.1 and PCI Express 3.0 are just a bit of icing on the fruitcake.

During our talks with AMD they teased a dual-GPU version of Southern Islands they were calling "New Zealand".  According to a report from Softpedia that card might be available sooner than we thought - sometime in the first quarter of 2012.  Because the new Tahiti GPU is actually more power efficient than Cayman, seeing the pending Radeon HD 7990 with two full powered GPUs isn't out the question though we would expect to see slightly lower clock speeds.

Because of the ZeroCore Technology implemented this generation of GPU from AMD, the HD 7990 will be able to run at basically the same power levels as the Radeon HD 7970 at idle and at the Windows desktop. 

The most interesting part?  This would give the HD 7990 a 6GB frame buffer, 3GB per GPU as we see today on the HD 7970.  Chances are this would give the graphics card more memory than many of our readers primary computer...

If you are interested in this type of card, start saving your pennies now.  When the Radeon HD 6990 launched (the Cayman-based dual-GPU card) it was priced at $699 and never went any lower.  With the price of a single Southern Islands GPU curently at $549, expect to see even higher numbers than the HD 6990 has.  I hope we don't see the same availability issues with the pending HD 7990 release but you can't be sure.

The First 28nm GPU Architecture

It is going to be an exciting 2012. Both AMD and NVIDIA are going to be bringing gamers entirely new GPU architectures, Intel has Ivy Bridge up its sleeve and the CPU side of AMD is looking forward to the introduction of the Piledriver lineup. Today though we end 2011 with the official introduction of the AMD Southern Islands GPU design, a completely new architecture from the ground up that engineers have been working on for more than three years.

This GPU will be the first on several fronts: the first 28nm part, the first cards with support for PCI Express 3.0 and the first to officially support DirectX 11.1 coming with Windows 8. Southern Islands is broken up into three different families starting with Tahiti at the high-end, Pitcairn for sweet spot gaming and Cape Verde for budget discrete options. The Radeon HD 7970 card that is launching today with availability in early January is going to be the top-end single GPU option, based on Tahiti.

Let's see what 4.31 billion transistors buys you in today's market.  I have embedded a very short video review here as well for your perusal but of course, you should continue down a bit further for the entire, in-depth review of the Radeon HD 7970 GPU.

Southern Islands - Starting with Tahiti

Before we get into benchmark results we need to get a better understanding of this completely new GPU design that was first divulged in June at the AMD Fusion Developer Summit. At that time, our own lovely and talented Josh Walrath wrote up a great preview of the architecture that remains accurate and pertinent for today's release. We will include some of Josh's analysis here and interject with anything new that we have learned from AMD about the Southern Islands architecture.

When NVIDIA introduced the G80, they took a pretty radical approach to GPU design. Instead of going with previous VLIW architectures which would support operations such as Vec4+Scalar, they went with a completely scalar architecture. This allowed a combination of flexibility of operation types, ease of scheduling, and a high utilization of compute units. AMD has taken a somewhat similar, but still unique approach to their new architecture.
