Conclusion
The PentiumŪ III processor is now in production on frequencies of up to 550 MHz. The 70 new instructions that were added were done at a cost of an additional ~10% in die size. The features that we have described have enabled the Pentium III processor to achieve superior multimedia performance. One more important feature is that our fairly straightforward implementation of the 4-wide Internet SSE and concurrency of the computational and memory streams allows for further performance scalability of SSE applications moving toward higher frequencies.
