Late last year, we covered the first part of AMD’s HD 7000M product lineup, the 7400M, 7500M, and 7600M. Today, the other shoe drops as we get the high-end parts, and unlike the other 7000M chips, these will all be running AMD’s GCN (Graphics Core Next) architecture. As is customary for mobile GPU launches, we don’t have any hardware in hand to test, and we’ve previously reported some of the details for the chips. Now we have complete specs to discuss, so let’s get to it.

In 2009-2010, AMD launched the entire 4 chip Evergreen series in 6 months. By previous standards this was a quick pace for a new design, especially since AMD had not previously attempted a 4 chip launch in such a manner. Now in 2012 AMD’s Southern Islands team is hard at work at wrapping up their own launch with new aspirations on quickness. Evergreen may have launched 4 chips in 6 months, but this month AMD will be completing the 3 chip Southern Islands launch in half the time – 3 chips in a mere 3 months.

To that end today AMD is taking the wraps off the final piece of the Southern Islands puzzle: Pitcairn. The middle child of the family, it will be the basis of AMD’s $250+ enthusiast segment Radeon HD 7800 series. We’ve seen AMD capture the high-end with the 7900 series and struggle to control the mainstream market with the 7700 series, but how does the 7800 series fare amidst AMD’s lead in deploying 28nm GPUs? Let’s find out.

With the launch of Tahiti behind them, AMD is now firing on all cylinders to get the rest of their Southern Islands lineup out the door. Typically we’d see AMD launch their GPUs in descending order of performance, but this time AMD is taking a slight detour. Rather than following up the Tahiti based 7900 series with the Pitcairn based 7800 series, AMD is instead going straight to the bottom and launching the Cape Verde based 7700 series first.

Today AMD will be launching two cards based on the Cape Verde GPU: the Radeon HD 7750, and the Radeon HD 7770 GHz Edition. As the Juniper based 5700 series never got a proper Northern Islands successor, this is the first real update for the x700 series since the launch of the 5700 series in October of 2009. Given the success of the 5700 expectations are going to be high, and to fulfill those expectations AMD will be bringing to bear their new GCN architecture along with a full node jump with TSMC’s 28nm process. But will this be enough to enable the 7700 series to replicate the success of the 5700 series? Let’s find out.

Announced late last month and shipping 3 weeks ago, AMD kicked off the 28nm generation with a bang with their Radeon HD 7970. Combining TSMC’s new 28nm HKMG process with AMD’s equally new Graphics Core Next Architecture, AMD finally took back the single-GPU performance crown for the first time since 2010 with an all-around impressive flagship video card.

Of course AMD has always produced multiple video cards from their high-end GPUs, and with Tahiti this was no different. The second Tahiti card has been waiting in the wings for its own launch, and that launch has finally come. Today AMD is launching the Radeon HD 7950, the cooler, quieter, and cheaper sibling of the Radeon HD 7970. Aimed right at NVIDIA’s GeForce GTX 580, AMD is looking to sew up the high-end market, and as we’ll see the Radeon HD 7950 is exactly the card to accomplish that.

Traditionally the launch of a next-generation high-end video card has been a staggered process. In the name of getting cards out as soon as possible the first cards are almost always reference cards coming preassembled straight from AMD or NVIDIA, which are then touched up in the livery of their partners before being boxed and sold. Only later on – particularly when there’s a solid supply of GPUs – can partners acquire individual parts and put together their custom designs.

But as it’s turning out the Radeon HD 7970 isn’t going to be a traditional launch. In a rare move AMD has loosened the leash on their partners just a bit, and as a result we’re seeing semi-custom cards planned for launch earlier than usual. XFX looks to be the first partner to take advantage of this more liberal policy, as alongside the reference cards being launched today they’re launching their first semi-custom 7970s

Update: This article was originally posted on June 17, 2011. We are pushing it back up to the top as a quick refresher before upcoming articles...

We’ve just returned from sunny Bellevue, Washington, where AMD held their first Fusion Developer Summit (AFDS). As with other technical conferences of this nature such as NVIDIA’s GTC and Intel’s IDF, AFDS is a chance for AMD to reach out to developers to prepare them for future products and to receive feedback in turn. While AMD can make powerful hardware it’s ultimately the software that runs on it that drives sales, so it’s important for them to reach out to developers to ensure that such software is being made.

While AFDS serves many purposes, the final purpose – and what is going to be most interesting to most outside observers – was to prepare developers for what’s coming down the pipe. AMD has big plans for the future and it’s important to get developers involved as soon as is reasonably possible so that they’re ready to use AMD’s future technologies when they launch. Over the next few days we’ll talk about a couple of different things AMD is working on, and today we’ll start with the first and most exciting project: AMD Graphics Core Next, AMD's next generation GPU architecture.
