Toshiba A505D-S6987: A Look at Turion II Ultra M600 Performance

Testing on the Toshiba A505D used our usual suspects. We expect the Turion II to perform well; maybe not spectacularly but certainly respectably for a budget-conscious mainstream notebook. This is also the fastest AMD mobile processor we've tested yet, so we're eager to see how it works out. Here's a refresh of the configuration of our review unit:
| Toshiba A505D-S6987 Test System | |
| Processor |
AMD Turion II Ultra M600 (2x2.4GHz, 45nm, 2MB L2, 35W) |
| Chipset | AMD RS880M Northbridge, AMD SB750 Southbridge |
| Memory | 2x2GB DDR2-800 (Max 2x4GB) |
| Graphics |
ATI Mobility Radeon HD 4200 (40 Stream Processors, 500MHz Core, Integrated) |
| Display | 16" LED Glossy 16:9 720p (1366x768) |
| Hard Drive(s) | Toshiba 500GB 5400 RPM Hard Disk |
| Optical Drive | Slot-loading DVD+/-RW Combo Drive with LabelFlash |
| Battery | 6-Cell, 12V, 44Wh battery |
| Operating System | Windows 7 Home Premium 64-bit |
| Pricing | $654 Online |
For our basic synthetic benchmarks we're using PCMark05 and PCMark Vantage to get a feel for how the Turion II Ultra M600 stacks up.
More or less falling in line with our expectations, the Turion II Ultra doesn't get murdered by comparable Core 2 Duo based machines, but it also can't really hang with Core i3/i5 processors either. Still, performance is certainly respectable, easily beating netbooks and CULV systems and showing healthy gains on the other AMD processors.
The 2.4 GHz Turion II Ultra puts in a very healthy performance in our other benchmarks, achieving parity with and oftentimes edging out the competing Core 2 Duo chips. The Core i3/i5 processors are in another performance class entirely, but the Turion II's showing here augurs well for the tri-core and quad-core AMD mobile processors that are now starting to ship.

I'm REALLY looking forward to review of the Danube and Nile platforms, but these Tigris notebooks are just not interesting. horrid battery life in a 15.6+" form factor...blech.JarredWalton - Thursday, June 24, 2010 - link
I agree, but it does help set the stage for the next review, plus there are lots of Tigris laptops floating around. They perform well enough and often can be had for a song, provided you're not after long battery life in an ultraportable chassis.Anyway, the Toshiba A665-S6059 just arrived this evening, and I unpacked it a couple hours back. It's radically different in looks from the A505D, and it throws in a lot of other extras. Quad-core P920, HD 4200 + HD 5650, textured lid/palm rest, and a thinner chassis to boot. Granted, it costs $875, but it looks like it idles at around 13-14W. That's still only good for 3.5 hours of battery life, but blame it on the paltry 48Wh battery. We'll have the review ready for next Friday is the plan....

Oh, I see, Jarred. Keeping all the fun ones to yourself? ;)pmonti80 - Thursday, June 24, 2010 - link
What I would love is laptops with AMD's new CULV equivalent. Don't remember the name though.JarredWalton - Thursday, June 24, 2010 - link
That's the Nile platform, which is the lower wattage version of Danube. We're working to get one of those for testing as well. An no worries, Dustin... we'll get you some other stuff. ;-)Roland00 - Thursday, June 24, 2010 - link
Here are the specific models of the new Nile PlatformThe Nile platform (2010) are 9W, 12W, 15W processors with DDR3 support. All these processors are Champlain processors with the new memory controller.
9W, AMD V105, Single Core*1.2 Ghz, 512 kb L2 cache total
12W, AMD K125, Single Core*1.7 Ghz, 1 mb L2 cache total
12W, AMD K325, Dual Core*1.3 Ghz, 1 mb L2 cache per core, 2mb total
15W, AMD K625, Dual Core*1.5 Ghz, 1 mb L2 cache per core, 2mb total
15W, AMD K665, Dual Core*1.7 Ghz, 1 mb L2 cache per core, 2mb total
The Danube platform (2010) are 25W, 35W, 45W processors with DDR3 support

Ooooh. Quad core + HD 5650 for $850 sounds like fun. It doesn't look all that great though (and the screen is pretty sadly low res - 1366x768 is not okay on a 16" display) and Toshiba is quoting 2.5 hours of battery life. That's not a good sign right off the bat. I'm scared for the results battery life tests, though it doesn't sound like they should take very long ;)Should be interesting to see how AMD's "more cores for less money" strategy works in the mobile space. Just gonna place a bet that it won't work as well as the desktop chips for two reasons: power consumption and heat. Will wait for benchmarks though, it should have a lot of fun with the encoding benches.

Initial idle battery life testing is under way, and it's looking like 3.5 hours is going to be about right. Obviously, Internet and x264 will put a much bigger load on the system. 2.5 hours seems about what you'd get if the HD 5650 stayed active.Quirky system, though: I haven't found a way to disable the dGPU other than unplugging the laptop. I mean, sure, if you're plugged in having the GPU enabled is reasonable, but I do wish there were a way to manually engage/disable it. Also, the lack of AMD driver updates is disheartening... and there's not even an ATI CCC with the current drivers, so I'm not sure what version of the drivers it's running.
$850 is a tough sell given the competition, but at least it looks like battery life won't be bad. The 1.6GHz clock speed may prove a bigger issue for some, but for heavily threaded workloads the quad-core CPU should come close to (or surpass even) some of the i3/i5 processors.

hello. i'm the proud owner of an acer timeline 3820TG featuring an i5 540m and a switchable (manually) 5470 which i do not really need... but that is a different story. i read some reviews and they were complaining that you cannot turn off the discrete card when plugged in. that is not true and it's also not so obvious.goes like this: when you plugin the lappie the discrete ati gpu goes active. then you can go to the ati control center (or something) and there it says that the discrete ati gpu is active. you also have two buttons: one is to enable the "power saving gpu" and one is for the... err power hungry and hot gpu. :) you have to press the button that sys about enabling the power saving gpu and wait. it takes a bit of time to make the switch and the desktop may go dark.. etc but after a while it will say that the integrated gpu is active. all this is on a special page... and you just have to find it. good luck!

Does it have AMD's Turbo-whatever? If it does, does it work well?
