By the time you'll want to upgrade your little Pentium HTPC, you'll be able to pick up an i7 on that socket for dirt cheap!
By the time you'll want to upgrade a way better generation/core/socket will be available and you won't buy that i7 anyway.
I just noticed my local MicroCenter has them in stock - AM1 1.3Ghz 25W "Sempron" quad core Kabini chips for $37.
No AM1 motherboards yet from a source I call reliable, the ones out there on Google shopping seem to be running $35-55 though.
The biggest competition to these kabini chips is baytrail.
Baytrail is soldered onto the mobo but that allows for lower costs.
But honestly the pricing looks like pricing to fail. The price of cheap Celerons + Mobo are maybe $70. Sure the TDP is higher but the power usage is going to be very similar.
$37 leaves $32 for a mobo. Possible but unlikely. When you get to the more expensive kabini parts it looks even more unattractive. $60 for top end Kabini is ludicrous.
Really think AMD should have gone embedded with kabini. On a system this cheap, low powered, and low performance few people are going to upgrade. I think AMD went this way so that they can get a bigger cut by selling individually.
Cheapest MB is around $42 here in Europe, so $32 in U.S. is quite likely. The
$77 model comes with 4 SATA ports and every video output one can think of (VGA, DVI, DP, HDMI): it's pricey for an AM1 board but would make a good HTPC buy.
Baytrail should have been main competition, but in my case it failed from the spec sheet: with prices of
$96 and $
125, the two Gigabyte - Bay Trail embedded MBs offer only 2 SATA ports and no PCIe slots. Maybe that will change with other models, but for now this lack of features and flexibility is a no go for me. At $125 the quad core Bay Trail ain't cheap either.
The embedded IVB Celerons are indeed nice competition for the Kabini: nice CPU, enough SATA ports, PCIe x16 slot (some of them at least), likely cheaper overall. They lack USB 3.0 though. Because.... differentiation.
