I wonder how many servers are currently CPU-bound? I've always been I/O bound (interchange that with memory-bound, depending on how much you would like to spend on memory).
Considering there is 8 meg of cache for all the cores, this must be for CPU-bound tasks only
Each core in Knights Corner runs at 1.2GHz, is supported by 512-bit vector processing units, has 8MB of cache, and four threads per core. That's 200 simultaneous threads. Wow. That's almost like a GPU.

Once established in this market, the feedback loop with users who pay money will drive the technology to improve to suit that niche. The bugs will get ironed out, deficiencies worked around, specific infrastructure developed. Chips will use less power, and will get faster and cheaper.
Eventually, other uses will be found for the product - perhaps on the desktop, perhaps as mobile devices, perhaps in applications that were never imagined before, because they were not conceivable. The key benefit might be from a feature that is not considered very central to the technology, from an engineering perspective, but happens to be unique with respect to the alternatives.
Perhaps it could be compact size, low power consumption, doing many distinct tasks, greater reliability through redundancy.

The article says that it has 8mb of cache per core, shared by four hardware threads.

That's 400MB of cache on the die, which seems highly unlikely.
