New Radeon 6990M will go head to head with NVIDIA's 580M; AMD thinks it can beat it

Advanced Micro Devices, Inc.'s (AMD) Fusion processors may be stealing the spotlight, but AMD is determined to show gamers that it still wants to give them a whole lot of love.  With Radeon 6990 being arguably the king of single-card desktop graphics performance today, AMD has unleashed a powerful mobile GPU that it claims is "the world's fastest notebook GPU."

The chip is named the Radeon HD 6990M and it packs 1120 stream processing units (SPUs) -- up 16.7 percent from the 960 found in AMD's previous top end offering, the Radeon 6970M.  Texture units (56) and the core clock (715 MHz) have also been bumped.  ROPs and memory clock remain the same.  However, in the memory department, the Radeon 6990M packs 2 GB of GDDR5.

The GPU may confuse some in that it's a single-chip (Barts) design, unlike the dual-chip (Cayman Islands) design found in the desktop Radeon 6990.  The chip also contains a mixture of features from the Evergreen and Northern Islands families, meaning that it's not exactly like its desktop 6000 series brethren.

Slides from AMD show the chip outperforming both its own Radeon 6970M and NVIDIA Corp.'s (NVDA) GeForce GTX 580M in games like Batman Arkham AsylumDragon Age 2Shogun 2BattleForgeLeft 4 DeadMetro2033, Wolfenstein MPThe Chronicles of Riddick, and ET: Quake Wars.  No independent benchmarks have been released yet, so the validity of these claims depends on how much you're willing to trust AMD.

The chip will land as an option for Dell Inc.'s (DELL) Alienware M18x and Clevo's P170HM and P150HM notebooks, both of which also offer the GTX 580M.  

These notebooks may support Crossfire configurations of more than one 6990M.  One 6990M is pretty far from its desktop namesake, but two could offer somewhat closer performance.  A Radeon 6990 has 3072 SPUs, while a pair of 6990Ms would have 2240 SPUs.  Unless you're mining bitcoins or counting framerates, the performance of a pair of 6990Ms and a Radeon 6990 should be virtually identical in current generation PC titles.

AMD has said that the new chip will support Eyefinity, HD3D, and all its other latest and greatest technology.  According to AnandTech, though, the chip will not support switchable graphics (à la NVIDIA's Optimus).  That, says AMD, is currently reserved for lower end CPUs.

The chip is available immediately, and AVADirect is already making the GPU available in its gaming notebooks.  Expect more manufacturers to jump on the AMD bandwagon in the near future.

It doesn't suck at all. You get the power of a desktop in a very small form factor and you can play or work on 3D anywhere.

You're trading batter life sure, but look at the bright side. You don't have to lug a giant screen and computer case around. Like this guy: http://www.youtube.com/watch?v=EKEeHREK2nQ

I agree why do people think there is going to be some magic, you want better battery life you sacrifice power there is no magic way around it. Even smart phones now days are like that almost no one can use a smart phone for more than 1 day strait. Back in the day dumb phones with last me almost a whole week on a charge. But the difference is now I can do so much more on a phone. In fact smart phones have made it so I care even less now how long my batter lasts on my laptop. I can take notes and surf the web on my phone and just use my laptop battery to get me through a 1 hour meeting. And in trade for a loss in battery life I have so much more power for everything I need and I like it.

The only thing that has me wondering if I will upgrade now is the 120hz laptop displays if they drop those in these laptops I and they perform fast I will be very interested.

Not really, with a laptop that huge its not really that portable.
