We are right in the middle of CES 2010, which naturally means it's a great time for tons of product announcements. Intel and their partners are busy launching the new i3/i5 processors, and AMD is taking this opportunity to announce the next version of their Mobility Radeon lineup. Yesterday, we discussed NVIDIA's quiet launch of the GT 240, and while we weren't impressed with the price/performance offered, at least we were able to get some hardware to test. As with most mobile GPU "launches", all we have right now are specifications and features. We will have to wait to get some laptops before we can provide concrete performance numbers. With or without independent performance, today ATI is announcing their new 5000 series DX11 mobile GPUs.

Performance with ATI's mobile graphics chips has generally been competitive with NVIDIA products in recent years. In fact, ATI is keen to point out that their market share for discrete mGPUs has increased to over 60% in 2009, with a whopping 13% increase in 2Q09. Since NVIDIA is the only other discrete mobile graphics solution, ATI's win is NVIDIA's loss.

That of course doesn't tell the full story, and in speaking with ATI we were informed that 70% of sales have been 4300/4500 parts - the lowest performing, least expensive offerings. 15% of sales are from the 4600 series, which is where reasonable gaming can finally enter the picture. As for the 4800 series, it's still sitting at less than 5% (with the remainder of ATI's sales apparently coming from older 3000 series parts). NVIDIA also sells far more low-end and midrange mobile GPUs than high-end parts, but as far as high-end laptop graphics is concerned, NVIDIA has had a clear lead for a while, for a couple of reasons.

First, NVIDIA has been very good about OEM/ODM design wins for their fastest GPUs. In contrast, we are only aware of two laptops that shipped with the Mobility Radeon 4870 chips. We're still running G92b cores in the GTX 280M, and the G92 first became available almost 2 years ago with the 8800M series. With only minor tweaks to the design, it has been easy for manufacturers to update existing lines with support for new NVIDIA graphics solutions. We've seen Gateway, ASUS, Dell, Clevo, and others go from 8800M to 9800M to GTX 260M/280M with very few updates to accommodate the new GPUs. That's good for the manufacturers, but we're not particularly happy that laptops are still less than half the performance of desktop parts. Then again, it's difficult to deal with laptop power and cooling constraints.

The other big reason that NVIDIA has ruled the high-end of mobile solutions is driver support. We tested the ASUS W90Vp and found that it can offer compelling performance… when the drivers worked properly. This is especially important for CrossFire and SLI solutions, and that's the one area where ATI's Mobility Radeon drivers have been severely lacking. (And as a side note, we still haven't seen much in the way of driver updates for that platform!) We asked ATI about this and were told that an improved mobile driver plan should be coming "very soon". Frankly, if the Mobility Radeon 5800 series is going to have any chance at winning gamer mindshare, those plans can't come soon enough. And of course, NVIDIA also has CUDA and PhysX to talk about. ATI in turn has Stream, and DirectCompute and OpenCL are industry standards that will hopefully supersede CUDA and Stream, but for the time being we have to give the GPGPU crown to NVIDIA.

In short, while ATI has had very compelling performance on the desktop - in fact they have been our recommended solution with the 5000 series, and the 4000 series was very good from a price/performance standpoint - on laptops ATI has been more of a multimedia solution than a gaming solution. That's fine and ATI is clearly getting design wins, but don't try to convince us that low-end discrete graphics (HD 4330 and GeForce 9300M/G110M, we're looking at you!) are anywhere near being good gaming solutions. At best, they are barely adequate, capable of running the majority of games at 1366x768 and low detail settings. If that's all you need, or if you don't even need gaming performance and are just interested in multimedia solutions, forget about discrete graphics and go with an IGP.

Okay, enough talk about the past; let's look at what AMD is announcing today. What we really want to know is if performance and compatibility are going to be where we want. Unfortunately, all we have are some figures from ATI regarding gaming performance, and until we see updated driver plans we won't know what to expect in terms of compatibility. But then drivers have only really been important if you're running high-end solutions, which is less than 5% of the laptop market.

    As far as I can tell, yes -- see slide #19 in the gallery. It states the chips support Dolby TrueHD, DTS-HD Master Audio, AC-3 and DTS with up to 8 channels of 192KHz/24-bit audio. Reply

    I guess this means that no ATI DX11 notebooks will have double precision float capability which is disappointing considering their previous gen high-end notebook GPUs could do it. It's interesting that Juniper (RV840) doesn't support DP floats while it's immediate predecessor, the RV740 used in the Radeon 4770 and Mobility Radeon 4830 and 4860 were DP float capable.

    Here's hoping that Apple will adopt at least the Mobility HD 5650 (15-19W TDP) in their next MacBook Pro refresh. The 8600M GT and 9600M GT had 23W TDPs I believe, making the Mobility HD 5730 (26W TDP) and Mobility HD 5750 (25W TDP) options as well. The Mobility HD 5750 would of course be ideal and the lower TDP than the Mobility HD 5730 is presumably due to the lower core clocks in the former which should be offset performance-wise by using GDDR5 rather than GDDR3 in the later.
