Intel Wants To See 48-Core Processors In Future Smartphones

Intel researchers located at the company’s Barcelona, Spain labs are working on multi-core solutions. Specifically, the researchers are looking to bring massive numbers of processing cores to smartphones and tablets. The x86 chip giant hopes to see as many as 48 core processors powering mobile devices within the next five to ten years.

Currently, quad core System on a Chip (SoC) processors represent the highest number of cores in a mobile device, so a 48 core processor would be an absolutely massive jump. Of course, there are several issues that Intel will need to address in order for such a chip to be feasible. The package size, TDP, and power draw will all need to be drastically reduced in order to fit into the power envelope and form factor of smartphones in particular. The biggest issue standing in the way of such a chip though is software. Massively multi-threaded software is still extremely rare, and on mobile devices is no where close to effectively utilizing the number of cores Intel wants to provide.

Analyst Patrick Moorhead argues that five to ten years is effectively an eternity in technology-time, and by the time the hardware with massive numbers of cores is feasible, the software will be there. Intel is a bit less optimistic, but hopeful that developers will embrace the idea of multiple low power cores versus a few high clocked, power hungry cores. Such a transition in the software industry would allow smartphones to multitask much more efficiently than they do now, and would no longer have to comprise on the extent of background tasks in order to keep the user interface stable and snappy.

Intel is currently using cloud computers to analyze multi-threading and what tasks can be parallelized. The company envisions being able to encrypt email, listen to media, sync with backup services, and use voice recognition without needing to reach out to Internet-connected servers at the same time. Cores would be able to split the work or dedicate certain numbers of cores to tasks like the UI or video playback. Intel has already demonstrated the ability to turn off unused portions of the CPU to save power as well as its turbo boost modes to increase clockspeeds when there is TDP headroom. It will be interesting to see a 48 core chip, especially if software developers can be coerced into doing tasks with massive numbers of cores in mind.

Interestingly, AMD is going for heterogeneous cores (CPU cores, GPU cores, ARM cores, etc) while Intel is using its process node and chip technology lead to throw large numbers of homogenous cores at the problem of processing. In the end though, it all comes down to battery tech and software enabling these kinds of advancements. I'm hopeful that I'll see these kinds of currently mind-blowing chips in my future smartphone, however.

Computer World has a write-up with quotes from the Intel engineers working on the multi-core smartphone chip, which is worth a read. What do you think about the prospects of a 48 core chip in your handheld mobile device?

Good Post :), I think Intel and the rest of the industry has a while to go before we reach this point (48 core SoC's).

Although at this point, I cant help but think of the fact that having all that power in your phone would be cool and all, but if there are no apps to take advantage of it, then?...

This kind of future outlook also makes me think of a future were we might have a Star Trek like data pad, that we carry around, and its our whole computer, and whenever we want to use a full mouse/keyboard/monitor/ect we just dock it :D

This makes AMD sound like they're a step ahead of Intel here.

Here is a low power 2 ARM + 64 RISC core project funded on Kickstarter that will be on the market in 2013 Open Source SDK Multicore co-processor "the Poor man's Xeon Phi"
