Intel shows off 80-core processor
Intel has built its 80-core processor as part of a research project, but don't expect it to boost your Doom score just yet. — Chief Technical Officer Justin Rattner demonstrated the processor in San Francisco last week for a group of reporters …
Context & Ripple Effects
Intel had set a 2010 target of 32 cores on a processor, while its January processor announcements emphasized transistor changes aimed at speed and energy efficiency. The 80-core demonstration shows its research program testing a much more aggressively parallel design, rather than presenting a near-term consumer chip.
First-order effects
- Intel gains a public proof point for research into many-core processing, with Justin Rattner positioning the prototype as a technical demonstration rather than a gaming-performance product.
- Software developers targeting Intel's future many-core designs face a more immediate need to divide workloads across many simultaneous processing units.
Second-order effects
- Intel's processor rivals are pressed to show credible paths to higher core counts and efficient parallel performance, not simply faster individual cores.
- The value of a many-core processor shifts toward software and workloads that can use parallel execution, making raw core count an incomplete performance measure.
Third-order effects
- If research prototypes such as this move into products, processor competition will increasingly hinge on power-efficient parallelism and the software ecosystem that can exploit it.
- The gap between experimental core counts and consumer use underscores a structural transition: hardware advances require coordinated changes in programming tools and applications before they translate into mainstream performance gains.
The trend: Chipmakers are pursuing many-core architectures to raise computing throughput through parallel execution alongside transistor-level efficiency improvements.
