ARM Makes Its CPU Roadmap Public, Challenges Intel in PCs With Deimos and Hercules Chips (pcworld.com)

With PC makers like Asus and HP beginning to design laptops and tablets around ARM chips, ARM itself has decided to emerge from the shadows and unroll its roadmap to challenge Intel through at least 2020, PCWorld writes. From a report, which details ARM's announcement Thursday: ARM's now-public roadmap represents its first processors that are designed for the PC space. ARM, taking aim at the dominant player, claims its chips will equal and potentially even surpass Intel's in single-threaded performance. ARM is unveiling two new chip architectures: Deimos, a 7nm architecture to debut in 2019, and Hercules, a 5nm design for 2020. There's a catch, of course: Many Windows apps aren't natively written for the ARM instruction set, forcing them to pay a performance penalty via emulation. Comparing itself to Intel is a brightly-colored signpost that ARM remains committed to the PC market, however.

ARM-powered PCs like the Asus NovaGo offer game-changing battery life -- but the performance suffers, for two reasons: One, because the computing power of ARM's cores has lagged behind those of the Intel Core family; and two, because any apps that the ARM chip can't process natively have to be emulated. ARM can't do much about Microsoft's development path, but it can increase its own performance. Finally, if you were concerned that ARM PCs will be a flash in the pan, the answer is no, apparently not.

Re:how meny pci-e lanes / other io does it have?

[Gravis Zero]

ARM is fabless and therefore only designs CPU cores. This means it's up to the chip maker to include a PCI-e interface. So far, everyone making ARM chips cares fuckall about PCI-e and therefore they don't add any too their chips because all they care about is making smartphone chips.

Returning to desktop

[GreatDrok]

It would be more accurate to say ARM is returning to the desktop market. The original ARM (Acorn RISC Machine) based Archimedes was a very fast 32 bit desktop machine released in the mid 1980's and I remember being amazed at the performance which utterly trounced anything Intel could produce at the time. I even used an Acorn R540 in 1990 which was running a nice UNIX environment and could even run a software PC to emulate both DOS and Windows on top of that. It took years before Intel was even in the same ballpark as the ARM from those days and even through the 90's there were plenty of chips that were much faster than anything Intel could make (Alpha for instance, what a joy!) and it is a shame that in the last 20 years or so we've seen most of these die off. Time for some new blood.
