Innovations in memory, communications
Intel has also made innovations in memory technology. Robson Technology, which has NAND Flash cache, has 1.5X faster application load times, has 1.5X resume from hibernate, gives 0.4W average power savings, and is used in the Santa Rosa platform.

The other innovation is solid-state drives. These are embedded in a range of devices, from handhelds to servers. Compared to HDDs, these give 1/10th the power, >10X performance, and are 1,000X more durable.

Innovations in communication technology include things like adaptive antenna and front-ends, digital CMOS radio, and reconfigurable baseband. Intel has also developed the world's 1st TeraFLOPS supercomputer on a die. It features 80 cores, 1TFLOP at 62W, and 256 GB/s bisection.

Intel has also unleashed the era of tera. These are in the form of tera bits –- Si Photonics and tera bytes –- 3D stacked memory. The latter includes 256KB SRAM per core, 4X C4 bump density, and 3200 thru-silicon vias.

Similarly, Intel's innovation in tera-scale software include RMS workloads, C++ for parallelism, Ct for nested data parallelism (race-free irregular parallel computation), and hardware assisted STM C transactional memory, which ensures concurrent access with no errors.

Intel has also done innovations for emerging regions. Rattner touched upon Research (at the Berkeley Lablet), which involves a long-distance WiFi solution: 6Mb/s at 100+ km. This has been tested at the Aravind Eye Hospital in Tamil Nadu. It has allowed doctor/patient videoconferences. Thirteen rural villages have been connected so far, going on to 50 villages. The impact has been tremendous -- 2,500 exams per month, over 30,000 so far; cataracts, glaucoma, cornea problems have been diagnosed; and 3,000 people have had their vision restored so far.

Intel has been a champion in innovating through collaboration. These have been in form of academic open-collaborative (pre-competitive research) -- Carnegie Mellon, Berkeley, University of Washington; industrial partnerships (product differentiation) -- an example being the ciscointelalliance.com, and consortium (ecosystem benefit) -- via the ISA, Continua, Innovation Value Institute, Trusted Computing Group, etc.

Intel's focus areas for 2008 include:
a) tera-scale computing -- unleashing the next generation of applications.
b) Platform* on a chip (POC) -- 'Platform' integration on chip with IA.
c) Trusted services -- technologies for secure service opportunities.
d) Carry small, live large -- context aware usage models and platforms.
e) Ultimate connectivity -- connected 'all-ways' for future platforms.
