If there is one thing that Intel is good at, it is writing a really big check to go in a new direction right when absolutely needed. Intel has released press information on what should be expected from their presence at the International Solid-State Circuits Conference which is currently in progress until the 23rd. The headliner for Intel at this event is their Rosepoint System on a Chip (SoC) which looks to lower power consumption by rethinking the RF transceiver and including it on the die itself. While the research has been underway for over a decade at this point, pressure from ARM has pushed Intel to, once again, throw money at R&D until their problems go away.

Intel could have easily trolled us all and have named this SoC "Centrino".

Almost ten years ago, AMD had Intel in a very difficult position. Intel fought to keep clock-rates high until AMD changed their numbering scheme to give proper credit to their higher performance-per-clock components. Intel dominated, legally or otherwise, the lower end market with their Celeron line of processors.

AMD responded with series of well-timed attacks against Intel. AMD jabbed Intel in the face and punched them in the gut with the release of the Sempron processor line nearby filing for anti-trust against Intel to allow them to more easily sell their processors in mainstream PCs.

At around this time, Intel decided to entirely pivot their product direction and made plans to take their Netburst architecture behind the shed. AMD has yet to recover from the tidal wave which the Core architectures crashed upon them.

Intel wishes to stop assaulting your battery indicator.

With the surge of ARM processors that have been fundamentally designed for lower power consumption than Intel’s x86-based competition, things look bleak for the expanding mobile market. Leave it to Intel to, once again, simply cut a gigantic check.

Intel is in the process of cutting power wherever possible in their mobile offerings. To remain competitive with ARM, Intel is not above outside-the-box solutions including the integration of more power-hungry components directly into the main processor. Similar to NVIDIA’s recent integration of touchscreen hardware into their Tegra 3 SoC, Intel will push the traditionally very power-hungry Wi-Fi transceivers into the SoC and supposedly eliminate all analog portions of the component in the process.

I am not too knowledgeable about Wi-Fi transceivers so I am not entirely sure how big of a jump Intel has made in their development, but it appears to be very significant. Intel is said to discuss this technology more closely during their talk on Tuesday morning titled, “A 20dBm 2.4GHz Digital Outphasing Transmitter for WLAN Application in 32nm CMOS.”

This paper is about a WiFi-compliant (802.11g/n) transmitter using Intel’s 32nm process and techniques leveraging Intel transistors to achieve record performance (power consumption per transmitted data better than state-of-the art). These techniques are expected to yield even better results when moved to Intel’s 22nm process and beyond.

What we do know is that the Rosepoint SoC will be manufactured at 32nm and is allegedly quite easy to scale down to smaller processes when necessary. Intel has also stated that while only Wi-Fi is currently supported, other frequencies including cellular bands could be developed in the future.

We will need to wait until later to see how this will affect the real world products, but either way -- this certainly is a testament to how much change a dollar can be broken into.

This is no easy feat! To completely digitize and accurately transmit/receive 2.4GHz Wi-Fi is no easy task when it's embedded into the SoC. The complexity is tantamount to building the whole computer on a chip with a fpga to handle dac/adc. I think this will open up the phone/small tablet/embedded applications market to greater heights. x86 CISC SoCs will lead the way to performance that eventually marginalize RISC SoCs.
