VIA subsidiary Centaur Technology is rumored to be launching a new x86 processor at the end of August based on the "Isaiah II" architecture. This upcoming chip is a 64-bit SoC aimed at the mobile and low power space. So far, the only known implementation is a quad core version clocked at up to 2.0 GHz with a 2MB L2 cache. Benchmarks of the quad core Isaiah II-based processor recently appeared online, and if the SiSoft Sandra results hold true VIA has very competitive chip on its hands that outperforms Intel's Bay Trail Z3770 and holds its own against AMD's Jaguar-based Athlon 5350.

The SiSoft Sandra results below show the alleged Isaiah II quad core handily outmaneuvering Intel's Bay Trail SoC and trading wins with AMD's Athlon 5350. All three SoCs are quad core parts with integrated graphics solutions. The benchmarks were run on slightly different configurations as they do not share a motherboard or chipset in common. In the case of the VIA chip, it was paired with a motherboard using the VIA VX11H chipset).

For comparison, The Atom Z3770 is a quad core clocked at 1.46 GHz (2.39 GHz max turbo) with 2MB L2 cache and Intel HD Graphics clocked at up to 667 MHz supporting up to 4GB of 1066 MHz memory. Bay Trail is manufactured on a 22nm process and has a 2W SDP (Scenario Design Power). Further, the AMD "Kabini" Athlon 5350 features four Jaguar CPU cores clocked at 2.05 GHz, a 128-core GCN GPU clocked at 600 MHz, 2MB L2 cache, and support for 1600 MHz memory. AMD's Kabini SoC is a 28nm chip with a 25W TDP (Thermal Design Power). VIA's new chip allegedly supports modern instruction sets, including AVX 2.0, putting it on par with the AMD and Intel options.

The SiSoft Sandra benchmarks spotted by TechPowerUp suggest that the Centaur Technology designed chip has potential. However, there are still several (important) unknowns at this point. Mainly, price and power usage. Also, the GPU VIA is using in the processor is still a mystery though Scott suspects an S3 GPU is possible through a partnership with HTC. 

The chip does seem to be offering up competitive performance, but pricing and power efficiency will play a major role in whether or not VIA gets any design wins with system OEMs. If I had to guess, the VIA chip will sit somewhere between the Intel and AMD offerings with the inclusion of motherboard chipset pushing it towards AMD's higher TDP.

If VIA prices it correctly, we could see the company making a slight comeback in the x86 market with consumer facing devices (particularly Windows 8.1 tablets). VIA has traditionally been known as the low power x86 licensee, and the new expanding mobile market is the ideal place for such a chip. Its past endeavors have not been well received (mainly due to timing and volume production/availability issues of the Nano processors), but I hope that Centaur Technology and VIA are able to pull this one off as I had started to forget the company existed (heh).

The Third x86-based SoC Player: VIA & Centaur's Isaiah II

There might be a third, x86-compatible processor manufacturer who is looking at the mobile market. Intel has been trying to make headway, including the direct development of Android for the x86 architecture. The company also has a few design wins, mostly with Windows 8.1-based tablets but also the occasional Android-based models. Google is rumored to be preparing the "Nexus 8" tablet with one of Intel's Moorefield SoCs. AMD, the second-largest x86 processor manufacturer, is aiming their Mullins platform at tablets and two-in-ones, but cannot afford to play snowplow, at least not like Intel.

VIA, through their Centaur Technology division, is expected to announce their own x86-based SoC, too. Called Isaiah II, it is rumored to be a quad core, 64-bit processor with a maximum clock rate of 2.0 GHz. Its GPU is currently unknown. VIA sold their stake S3 Graphics to HTC back in 2011, who then became majority shareholder over the GPU company. That said, HTC and VIA are very close companies. The chairwoman of HTC is the founder of VIA Technologies. The current President and CEO of VIA, who has been in that position since 1992, is her husband. I expect that the GPU architecture will be provided by S3, or will somehow be based on their technology. I could be wrong. Both companies will obviously do what they think is best.

It would make sense, though, especially if it benefits HTC with cheap but effective SoCs for Android and "full" Windows (not Windows RT) devices.

Or this announcement could be larger than it would appear. Three years ago, VIA filed for a patent which described a processor that can read both x86 and ARM machine language and translate it into its own, internal microinstructions. The Centaur Isaiah II could reasonably be based on that technology. If so, this processor would be able to support either version of Android. Or, after Intel built up the Android x86 code base, maybe they shelved that initiative (or just got that patent for legal reasons).

But what about Intel? Honestly, I see this being a benefit for the behemoth. Extra x86-based vendors will probably grow the overall market share, compared to ARM, by helping with software support. Even if it is compatible with both ARM and x86, what Intel needs right now is software. They can only write so much of it themselves. It is possible that VIA, being the original netbook processor, could disrupt the PC market with both x86 and ARM compatibility, but I doubt it.

Centaur Technology, the relevant division of VIA, will make their announcement in less than 51 days.

VIA's new QuadCore processor proves low power and high performance are still cool

VIA has been sitting pretty in a very specific peice of the computer market for quite a while now and is now being crowded by AMD and Intel working their way down to the low power market from their usual energy gobbling silicon and ARM sneaking up its performance from its traditional extremely low power consumption market.   That competition has spurred VIA to develop first the dual core Nano X2 and now the QuadCore which is a pair of X2's on a single package using what was described to The Tech Report as a "side channel" of wiring between them.  Still on 40nm it doesn't represent a completely new design for VIA, more a refinement of what they already produce.  Check out their coverage as well as the write up Josh has finished here.

"Early this year, Via introduced its Nano X2 processor, a dual-core implementation of its Isaiah architecture built on TSMC's 40-nm chip fabrication process. Today, Via is announcing a new product, the QuadCore processor, that combines a pair of Nano X2 chips on a single package to deliver a low-cost, low-power CPU whose position in the market is fairly distinctive.

We visited Via-Centaur's Austin, Texas offices yesterday, where we chatted with Centaur Chief Architect Glenn Henry and Via marketing head Richard Brown. We came away with some fresh details on the QuadCore processor and a better sense of Via's future plans as an intriguing third-place supplier of x86-compatible PC processors."
