Single-Chip x86 Chipsets Around the Corner?
An anonymous reader writes "Kontron, a giant among industrial single-board computer vendors, yesterday revealed a credit-card sized board apparently based on a single-chip x86 chipset that clocks to 1.5GHz and supports a gig of RAM. It targets portable devices — not x86's usual forte. Kontron isn't saying whether the board uses a Via or an Intel chip(set) — both vendors reportedly have single-chip chipsets in the works, part of their respective missions to drive 'x86 everywhere.'"
AMD makes a whole line of embedded x86 processors. http://www.amd.com/us-en/ConnectivitySolutions/ProductInformation/0,,50_2330_9863,00.html
If the chip is codenamed John, as the article claims, it's a VIA chipset. VIA uses biblical names for their CPU codenames.
Previous VIA CPU codenames:
Samuel
Esther
Nehemiah
Ezra
Note also that VIA combined a C3 CPU and a northbridge into a single package - it was codenamed "Luke".
This isn't true because of some "law" that says x86 must be power hungry, it's true because nobody's really sat down and done an x86 processor for the embedded market, or at least not donw well. Check out Silverthorne, it has power use comparable to MIPS/ARM.
You can find articles about the use of x86 in embedded devices at arstechnica, from Jon Stokes:
Return of the Son of Pentium in 2008? Intel's new ultramobile processors
Intel's low-cost "Diamondville" CPU to power OLPC/Eee PC mobile category
And a very interesting article why processor makers want to extend their architecture to other realms: Beyond the BlackBerry crowd: life in a post-32nm world
Yeah, because there haven't been 386, 486, and other systems on a chip and Via doesn't have a 1-watt processor anywhere to be found. This is not the first 1-chip chipset for all of the x86 line. That's bullshit. An SoC is even more integrated than just having the chipset as one chip. Somebody never read the old Computer Shopper before it slimmed down. SoC solutions for x86-compatible systems have been around more than a decade. The summary is bad, because TFA does not say this is a first for the x86 line.
You're right that even low-powered x86 chips like the C7 and the Geode line are generally no match for ARM and XScale. MIPS I'm not as familiar with for power usage purposes. It'd be nice if that question was answered, but I'm afraid it'd be summarized incorrectly too.
