There are two non-negotiables in building a PC these days: the cost of Intel silicon and the cost of the Windows license. You can play with everything else but Intel and Microsoft are going to get their share. Those two relatively fixed costs in the PC bill of materials can do one of two things: encourage OEMs to skimp on component cost elsewhere, or drive the entire ecosystem to supply higher quality components at lower prices. If you’ve been following the PC industry for the past decade, I think we’ve seen more of the former and less of the latter.

Apple occupying the high-end of the notebook PC space has forced many OEMs to reconsider their approach, but that’s a more recent change. What AMD seems to offer is an easier path. AMD will take less of the BoM, allowing OEMs to invest those savings elsewhere - a move Intel will never make. Given how much pressure the PC OEMs have been under for the past few years, AMD’s bargain is more appealing now than it has ever been.

With Llano and Trinity, AMD’s story was about giving up CPU performance for GPU performance. With Kabini, the deal is more palatable. You only give up CPU performance compared to higher priced parts (you gain performance compared to Atom), and you get much lower power silicon that can run in thinner/lighter notebooks. Typically at the price points Kabini is targeting (sub-$400 notebooks), you don’t get pretty form factors with amazing battery life. AMD hopes to change that.

While AMD hasn’t disclosed OEM pricing on Kabini (similarly, Intel doesn’t list OEM pricing on its mobile Pentium SKUs), it’s safe to assume that AMD will sell Kabini for less than Intel will sell its competing SKUs. If Kabini’s die size is indeed around 107mm^2, that puts it in the same range as a dual-core Ivy Bridge. AMD can likely undercut Intel a bit and live off of lower margins, but there’s one more component to think about: Ivy Bridge needs its PCH (Platform Controller Hub), Kabini does not. As a more fully integrated SoC, Kabini’s IO duties are handled by an on-die Fusion Controller Hub. Intel typically charges low double digits for its entry level chipsets, which is money AMD either rolls into the cost of Kabini or uses as a way of delivering a lower total cost to OEMs.

Traditionally, OEMs would take these cost savings and pass them along to the end user. I get the impression that AMD’s hope with Kabini is for OEMs to instead take the cost savings and redeploy them elsewhere in the system. Perhaps putting it towards a small amount of NAND on-board for a better user experience, or maybe towards a better LCD.

As we found in yesterday’s article, Kabini does a great job against Atom and Brazos. However, even with double digit increases in performance, Kabini is still a little core and no match for the bigger Ivy Bridge parts. Much to our disappointment, we pretty much never get sent low end hardware for review - so to make yesterday’s NDA we had to stick with 17W Ivy Bridge and extrapolate performance from there. In the past day I grabbed an ASUS X501A system, a 15-inch entry-level machine priced in the low $300s. More importantly, it features a 35W Ivy Bridge based Pentium CPU: the dual-core 2020M.

The Pentium 2020M’s base clock speed is still relatively high at 2.4GHz, but there’s no turbo. In the low level CPU performance analysis yesterday I used a Surface Pro with a 17W 1.7GHz Core i5, but max turbo on that part can hit 2.6GHz. I actually don’t expect there to be huge CPU performance differences between the results from yesterday and what I have here but I wanted to be sure.

The bigger difference is actually on the GPU side. While a mobile Core i5 comes with Intel’s HD 4000 graphics, the Pentium 2020M gets a vanilla Intel HD GPU. At 22nm, Intel’s HD graphics is a 6 EU part with lower performance than the previous generation Intel HD 3000.

With that said, let’s see how Kabini (AMD’s A4-5000 in particular) compares to an Ivy Bridge based Pentium 2020M in CPU performance, GPU performance and finally in power.

    wow.... don't you know these are chips for ultra portable systems?? this article does not cover normal integrated laptop/desktop graphics... Reply

    So You have a highest-performing discrete laptop GPU from five years ago, which on its own pulls ~6x the whole system consumption of this netbook-APU, all the while being 3x as fast?

    Yea, you win internet.

    Well, you probably pulled 100W and more with that notebook for the GPU and CPU alone. Current high end Intel/AMD APUs use 35 to 45W and achieve 80% of that score. Reply

    I use an Asus transformer prime a lot and this would make a very good alternative to that and I get the option of a full windows setup to boot. In the last paragraph the Author talks about the X202E from ASUS. Kabini could give me another option.

    At the price they are talking about there is a plenty big market for something like this.

    Not everyone's playing the latest demanding 3D games, so even on budget systems there's room for usable low end graphics. Imagine this thing in a tablet form factor, and think about tablet-marketed 3D games. I think this gives a good balance for full-fledged Windows 8 tablets, though I doubt it'll ever make it in one (or many). Reply

    What about GPU accelerated applications? Reply

    A very interesting comparison, thanks for picking up a system so you could do this. Seems like the Jag competes pretty well at the low end.

    If it's truly a much cheaper SKU, it would bee nice to see some better quality / construction on a low spec laptop, but I'm afraid that the way the majority of the market shops you won't see it. I wanted an IPS atom or brazos laptop for some sideline work I do, but had to settle on a TN... after all, who would buy a low spec machine with a high spec display? (everyone with an iPad2 / mini...)

    Most laptops are ridiculously over-specced on CPU, as it's what many people look for. A Kabini CPU with an SSD is always going to be a better experience for office or multimedia use than an i3 with an HDD. Reply
