AMD’s Kabini Laptop Prototype

AMD shipped hardware sites special prototype laptops, similar to what we’ve seen in the past with Sandy Bridge, Llano, Ivy Bridge, and Trinity. These systems typically aren’t intended to hit retail outlets, though in some cases they may be very similar to production laptops; I’d guess that’s not the case with the Kabini prototype.

The laptop is actually very interesting in some areas, but it has major flaws in others—chiefly the build quality, keyboard, and touchpad. There’s more flex in this keyboard than in a steroid laced bodybuilding contest, and the feel of both the keys as well as the touchpad is poor at best. Those are areas that are easy to address, and given we’re not looking at hardware intended for retail sales it’s not too much of a problem; we only need the laptop for benchmarks right now.

If that’s the bad news, what’s the interesting aspect? The display. It’s the first high quality 1080p 14” LCD I’ve personally encountered. It’s an AU Optronics AHVA (Advanced Hyper-Viewing Angle) panel, model AUO B140HAN01.1. I’m hopeful that with AMD using such a panel in a prototype laptop, we may finally be nearing the end of the horrible 1366x768 panels…but don’t hold your breath.

Here’s the short rundown of the laptop’s hardware.

Just to call out a couple noteworthy items, first is the single-channel memory configuration. In theory that could be hampering performance somewhat, but we have no real way of knowing. While the laptop does support two SO-DIMMs, Kabini only supports a single-channel interface, so adding a second SO-DIMM wouldn't help.

The other configuration item I want to call out is the storage device, specifically the Toshiba HDD. Hard drives are slow, we all know this, but our experience over the past several years suggests that Toshiba’s 5400RPM hard drives are even slower than other offerings. Anand installed an SSD to run PCMark 7 for comparison, and that certainly helps with overall responsiveness. Realistically, though, we’re not at the stage where I expect laptops using Kabini to ship with SSDs—even an inexpensive 128GB SSD will increase the total BoM by 15% or more, which isn’t going to fly in the budget sector Kabini is destined to compete in.

Before we get to the actual benchmarks, let me go over the general impression of the system in day-to-day use. For much of what you might do (e.g. surfing the web, watching streaming videos, emailing, and office use), Kabini works well. Technically even Atom and Brazos can handle most of those tasks, but there’s a noticeable speed up in typical use. However, there are also occasions where the system really bogs down; some of that may be thanks to the slow HDD, or (less likely) the single-channel memory, but while Jaguar cores are a step up in performance from Brazos cores (never mind Intel’s Atom variants), they’re still nowhere near as fast as a Trinity or Ivy Bridge core.

What Kabini really brings to the table is ultra low power requirements with performance that’s a great match for ultraportable devices. We’ll see the Temash APUs (basically a lower power Kabini) in tablets, but Kabini may find its way into a few larger tablets as well as hybrid devices. At 9W and 15W TDPs, basically anywhere we’ve seen Intel’s ULV cores show up is a place that Kabini can go as well. There are compromises you’ll have to make one way or the other (faster CPU, faster GPU, battery life, drivers, features, etc.), and I don’t think there’s going to be a single “correct” solution for every device out there. Choice is the name of the game, and even if you decide Kabini may not be right for you at least it’s good to have an alternative.

    Ah, so that justified them doing it while they did do that, right? ;) Reply

    I know it's not on topic, but did anyone else see the add for the GTX 780 on anand's home page? Reply

    Only one test comparing it against an a15? There is trickery afoot. Reply
  • wumpus - Saturday, May 25, 2013 - link

    Or likely a lack of A15 based systems in Anand's test lab. HEY YOU! You with the A15 tablet samples. Send some to Anand. Reply

    looks ok now...but this will change in about 1 month and then even more so when baytrail-T arrives. Reply

    The article describes a 14 inch display, but the specs embedded in the article mention 15.6 inch screen... Reply

    A4-5000: half the performance of Haswell with all the TDP Reply
  • takeship - Thursday, May 23, 2013 - link

    It's even worse than that. Kabini can't compete in either CPU, or GPU perf with ULV Ivy-bridge, let alone Haswell. Less performance, slightly better battery life?, and likely cheapy cheap laptops sound the DO NOT WANT trumpet pretty loudly. Maybe if we could get this kind of performance at 7W instead. Reply

    Kabini will be priced under $60. What's Haswell going to be priced at again? $200? $300? Reply
