Budget DTR: The Toshiba Satellite L775D-S7206

Since Llano's introduction, the value of AMD's new APU has been the subject of some debate, even between editors here at AnandTech. With notebooks sporting the new A-series processors trickling out from vendors (and Toshiba waving the banner) it's been fairly difficult getting a good feel for what the chip brings to the table for the end user, but thankfully that's changing. Today we have on hand the Toshiba Satellite L775D-S7206, a budget 17" model that also gives us our first look at the AMD A6-3400M.

We had a chance to meet with Toshiba reps and preview their refreshed mobile line a couple of months back, and now I'm happy to say we have one of the new notebooks on hand for testing: the catchily named Satellite L775D-S7206. More than that, it's also an opportunity to further explore AMD's Llano APU and what it means for consumers at every point on the continuum as well as determine whether or not AMD's new offering can be price competitive with notebooks featuring Sandy Bridge processors and low end discrete NVIDIA graphics. Our review unit is equipped as follows:

Let's start at the top: the AMD A6-3400M APU is the second-fastest 35W mobile Llano chip available, behind the A8-3500M we've already reviewed with our introduction to Llano. AMD's Fusion initiative started grassroots with Zacate and the E-350 and its kin, sporting a single chip dubbed an APU to handle the CPU and graphics and then a single chip for the chipset, which AMD dubs an FCH or "Fusion Controller Hub." This is a major consolidation compared to what we're used to seeing from AMD in the mobile market: we've gone from a processor, northbridge, and southbridge down to just a single 35W-45W part and a low-wattage "northbridge" serving roughly the same functions as Intel's mobile 6 series chips.

Unfortunately, sacrifices were made. The A6-3400M sports four slightly-modified Stars cores with L2 cache per core bumped from 512KB to 1MB and no L3 cache, effectively putting the CPU half on par with an Athlon II. These cores are clocked at a low 1.4GHz, and while AMD has instituted a turbo feature to speed them up to as high as 2.3GHz depending on the workload applied to the chip, none of our monitoring software is yet able to actually track the processor speeds as they turbo up. We don't need to tell you the CPU half of Llano is nowhere near as powerful as Intel's Sandy Bridge, and if you've been following coverage of Llano this is going to be old news to you.

Yet I suspect AMD knew they were going to take it on the chin where the CPU half of Llano was concerned, and they dish it out royally in the GPU side. Llano sports a modified Redwood core (Radeon HD 5670) with 400 stream processors in the VLIW5 configuration, 20 texture units, and 8 ROPs. In the A8 chip, this entire GPU core is present, while the A6 is slightly crippled, sacrificing 80 stream processors and 4 texture units, putting its specs roughly on par with the Radeon HD 4650/4670 (but with DX11). GPU clocks also take a hit from the spec of 444MHz, but it's a mild one, dropping down to 400MHz.

Essentially AMD hedged their bets, trading off processor power for GPU power, and this is one of the places where our opinions of Llano start to diverge. While it's true Llano's CPU half is hopelessly outclassed in every respect by Intel's processors, and I do honestly think two faster AMD cores would've been a better call than four slow cores, the vastly more capable GPU opens new avenues for mobile users, and the processor half is going to be fast enough for general use and light gaming. Essentially what Llano does is enable laptops that can game south of $600. Llano may not make much sense on the desktop (where I still feel the CPU and motherboard are priced out of competition), but in laptops it basically serves an entirely different market from Intel. It's not direct competition, but it's a foothold.

Moving on from Llano, it's a shame Toshiba has essentially crippled the L775D from every other angle but RAM, which is a generous 6GB. There are two available mobile chipsets for the APU: the A60M and A70M, with the key differentiator being that the A70M supports USB 3.0 while the A60M does not. The L775D uses the A60M and thus is missing USB 3.0, and worse, Toshiba has even forgone gigabit ethernet in favor of ancient school 10/100 ethernet. The inclusion of Blu-ray is some consolation but not really enough, though if you need a Blu-ray-capable notebook for under $700 these sacrifices might make some sense to you. Finally, I'm happy to report Toshiba eschewed one of their own dog slow hard drives for a slightly better (though still 5400RPM) Hitachi drive.

Here's where things get difficult. All of the above would make for a fairly decent entry level laptop capable of moderate gaming, but the $699 MSRP would push into competition with better equipped offerings. Luckily, you can already find the similar L775D-S7226 for $599, which is very reasonable for a Blu-ray equipped notebook. As long as that sort of pricing holds, the L775D has plenty to offer.

    At 450 bucks Asus offers an A3400 with 1gb discrete graphics. I bought one and am amazed at how capable it is. Reply

    I think I just saw a Toshiba with a A4-3300M out there at Best Buy. I think it was priced at $399, so it was brushing up against E-350 pricing territory.

    I have not heard anything about this chip, though. Would like to get some reviews.

    I noticed in the laptop specs, only mention was made for 1x2GB and 1x4GB configurations; is that simply as tested (in which case, was it tested with 2GB or 4GB RAM? Can be big difference for Win7 depending on what is running..), or as available from Toshiba? Since we are talking about an IGP (sorry, iGPU ;-) ), you are contending for memory bandwidth for GPU and CPU access, adding memory bandwidth can only help both. Or is the memory controller not sophisticated enough to accomplish what even early gen Athlon CPUs could do? If so, is DDR-1600 the only way to free up RAM access bottlenecks? Could be a real cheap upgrade and cost savings to buy the 2GB version, and buy an extra 2GB chip to boost performance both due to physical RAM exhaustion and interleaving for collision reduction.

    Just wanted to give my 2 cents to the value of the A6 and why I just purchased one. I grabbed a Samsung 3 series from BestBuy yesterday for $399. It has the A6 3420m, 4Gb ram, 500GB 5400rpm hard drive, 1.3" thick and about 5 lbs. My reasoning for buying this was to take on an overseas deployment where it very well could not make it back. I wanted it cheap, able to skype, but also use it to play some games as my time sink. I've got WoW and about 15 games in steam loading on it as we speak, I'll repost when I can give more input on the performance. So far in windows, just loading webpages in chrome, downloading avast, steam, wow client, it all seems just fine. I'm really curious to see how well it will launch these games. Reply
