Toshiba Satellite A660D-ST2G01: AMD's Quad-Core Phenom II P920 Joins the Mobile Party

It's been a long time coming, but the Toshiba A660D-ST2G01 finally gets us an up-to-date AMD mobile platform. It has all the latest and greatest AMD enhancements, including switchable graphics and a quad-core processor. Running at 1.6GHz, the P920 happens to have the same base clock speed as the i7-720QM, but it lacks Intel's Turbo Boost technology. The result is going to be interesting; we expect slower performance overall, particularly in single-threaded workloads where the 720QM can Turbo up to 2.8GHz; we're also looking at the mobile equivalent of the desktop Athlon II X4 processors, since the P920 lacks L3 cache. On the other hand, AMD specs the P920 for 25W compared to 45W on the 720QM, and unlike Arrandale the quad-core Intel chips are still manufactured on a 45nm process.
The new Danube platform also makes the switch to DDR3, which should further reduce power requirements. Will the A660D finally give us reasonable battery life from a midrange AMD system? More importantly, how does it stack up to other options—with a $950 MSRP it goes up against far more than entry-level laptops. Before we get to the answers to those questions, let's go over the basic specs.

While many of the basic features are similar to the Toshiba A505D, the package as a whole is very different. For one, despite using the same size 16" LCD panel, the dimensions of the A660D are still slightly smaller in width and depth, and about a quarter inch thinner. The exterior is also a textured plastic that's not quite as much of a fingerprint magnet. The big changes are in the components, with a quad-core CPU, a discrete GPU with the ability to switch to the IGP, and DDR3 memory. The modem port is also gone, and the slot-load DVDR is swapped out for a standard DVDR. The eSATA/USB combo port also has Toshiba's Sleep and Chard functionality, which allows you to charge USB peripherals even while the system is powered down. Similarly, the speakers can be used with the system powered down if you connect to the line-in jack.
The remaining components and features are what we find pretty much everywhere, though with a few additions you don't always find. ExpressCard and eSATA are nice extras, as is the LED backlit keyboard. The internal speakers are better than most laptops, though they still won't beat a good set of external speakers or headphones. The battery is also rather small for a 6-cell unit, and downright puny when compared to some of the ASUS laptops that are using 84Wh batteries, but otherwise the specifications look reasonable.
For those interested in branding, the A660D is part of the AMD Vision Ultimate line. We talked about AMD Vision with the Toshiba T235D, and the A660D belongs in the higher performing Ultimate bracket. You can read the specifics of AMD's Vision Ultimate, but the quick summary is that notebooks with this branding should provide advanced multitasking, advanced photo editing, enough power to create and edit HD movies, and enough graphics horsepower to play modern games. We could say that any reasonable laptop meets many of those requirements, but the gaming requirement in particular means you need a discrete GPU (at least for now), and the HD 5650 definitely fulfils that requirement. It's not the fastest GPU on the block, but in the mobile world the number of graphics chips that are clearly faster is very limited.
While the $949 price is going to be too high for most, there's also an A665D-S6059 that has the same feature set but with a 500GB 5400RPM drive. You can find the A665D on Newegg for just $799, making it a far more attractive buy. We actually started this review way back in July, but we ran into complication when we received pre-production hardware that had a few glitches, creating some unfortunate delays. The problems we encountered on the early samples of the A665D have been fixed in the retail A660D—and presumably the A665D as well—so unless you really want to spend $150 for the upgrade to a 7200RPM drive there's no reason to choose the more expensive model. There's also an A665D-S6051 model that drops the HD 5650 and lowers the price about $60; while we have concerns with the 5650 drivers that we'll get to shortly, the $60 saved isn't enough to make the S6051 a better option.
Frankly, the $949 MSRP is far too expensive compared to the competition, but hopefully when the A660D starts showing up at vendors other than Toshiba Direct we'll see that price drop to around $850. As we pointed out in our mobile DTR buyers' guide, you can find the Acer 7740G with an i5-430M and HD 5650 for $750, or the Acer 7551 with a faster Phenom II N930 and HD 5650 for about the same price as the A665D. Toshiba also has the A505 with an i7-720QM for $900 online right now, with a GT 330M in place of the HD 5650. The 5650 should be faster and it has DX11 support, but the GT 330M is a decent mobile midrange part that should handle 1366x768 gaming quite well. We'll want to keep an eye on how performance of the P920 compares to the i5-430M as well as the i7-720QM, not to mention checking on battery life, to see if the A660D-ST2G01 and A665D-S6059 are a good value.

This quad core simply has no logical benefit to it. Who buys a quad core for price and battery life (given Intel's penchant for monopolistic behaviour, if this was a market segment worth worrying about we'd have a dedicated mobile i7 quad die not harvested desktop Lynnfields)Even in benches where it's sposed to benefit from highly multithreaded workloads - e.g. cinebench multi - it's beaten by a i3. Why would AMD even bother releasing something this poor is beyond me.
AMD notebooks like this don't sell because they don't make sense.

Wow... $950 for this? Amazon's selling the dv6-3050us with the Phenom II N930 for $890 and even cheaper on Newegg - better processor, driver support from AMD, and the GPU has normal clocks. Toshiba must put a premium for an ExpressCard slot or their cheap looking designs... What kinds of stupid thoughts go through the minds of that company's decision makers?I think it's time AMD started making their own special edition laptops with configurations OEMs aren't willing to put together. Why can't we get a MR HD5870 + Phenom II X920 BE?

That specific model has even been cheaper before. One week on newegg it was 779, and if you did a 50 MIR it was 729 AR. Another week Frys.com had a similar promotion where it was 799 and if you did a 50 MIR it was 749 AR.The Crying Man - Tuesday, August 31, 2010 - link
Yep, bought mine way back in July on Amazon when it was $775.blackshard - Tuesday, August 31, 2010 - link
Hello. Just a suggestion: check the battery wear level on this notebook (hwmonitor does it well). I just bought an Toshiba L650-10H with an AMD P520 (2.3 Ghz part) and HD5650. The video chip was clocked to 450 Mhz, as far as I remember. Anyway the 48Wh battery came with a silly 20% wear level, leaving around 39Wh for a brand new laptop. I don't know if it is a faulty battery or a "feature" coming straight from the factory, but it is enough for me to drop away toshiba notebooks.Also the display was the worst thing I've ever seen: the Windows 7 loading logo is exposing a really huge dithering problem with colors fading to black.

HWMonitor reports the wear level as 2%, which probably came from me going through 10-12 recharge cycles during testing. Now, I wish I could say as much for another laptop I just got, where the wear level is reporting at 30%. :-\larson0699 - Tuesday, August 31, 2010 - link
I'm on an A665 at work, P920, 4GB, 500GB, 16", $799. We've had this for a while now. But whenever I'm in early or need to get online during break, this is the machine I use. Absolutely brilliant on Toshiba's part. It's a shame we don't also sell Sony...hgd - Tuesday, August 31, 2010 - link

Doesn't 720QM have 45W TDP?

Correct. Fixed.Cal123 - Tuesday, August 31, 2010 - link
Acer has a P520 with 5650 in a 15.6" for only $599, I'd really like to see a review of that. It looks good to me, if Acer put it together well. I don't think Acer screws up the graphics like Toshiba does.Aspire 5551G-4591
