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.

    "Give me a reasonable Ultrabook-style chassis (or maybe a dockable tablet) with Kabini and a decent quality 1080p touchscreen and do it at the right price and there are plenty of people that will jump at the offer."

    I concur

    If you think Angela`s story is inconceivable,, a month-back my auntiez girl-friend basically also got a cheque for $8689 workin a sixteen hour week from home and there co-worker's mother`s neighbour has been doing this for 7-months and got a cheque for more than $8689 part-time on- line. applie the instructions available on this page, Bow6.comTAKE A LOOK Reply

    "There are two non-negotiables in building a PC these days: the cost of Intel silicon and the cost of the Windows license" this was a joke right? Intel has very nice CPU's so I'll agree with that, but MS? Linux helps You save those $ for better hardware :) Reply

    "There are two non-negotiables in building a PC these days: the cost of Intel silicon and the cost of the Windows license" You are joking right? Intel CPU's are great so OK with that, but Microsoft? Why is it a non-negotiable? I always choose more ram/better CPU and Linux instead of Windows. Unless You work with professional CAD software (< 0.1% of users) Windows is VERY negotiable. Reply

    oops double post. Seems strange that a new post appears at the top and after a refresh its gone to the bottom :) Reply

    I am a bit disappointed that you guys call yourselves PC experts, yet you guys are comparing this architecture's power consumption as bad for performance vs. an Core i3. The issue is you guys ignored the fact that Kabini is A SYSTEM ON A CHIP. BIG DIFFERENCE!!! If you want to properly compare the Core i3 to Kabini, then you guys should also include the power consumption of the support chips that the Core i3 requires since it is just the CPU. You guys should know better!!! You are not the ignorant consumer that goes to Wal-Mart and believes the sales guy. At least I hope not!! Reply

    "AMD will take less of the BoM,"

    Please if you are going to force us to read leet speak, please allow us less than high IQ types the benefit of a definition. Thank you. :)

    This is good for mobile, but a desktop APU, AMD needs major improvements because so far Intel takes the cake in the desktop! I would like to see AMD make an APU with 1.56 single thread performance and take advantage of the latest 7000 series graphic cards with there APU for desktops!
