SANTA CLARA, Calif. — Here's a surprise. Benchmark test results from Intel show its new 815E chip set with PC133 SDRAMs beating the performance of its 820 chip set with Direct Rambus memories.

Rambus had no comment as of Monday morning. There was no comparative data on four benchmarks, which Intel used for testing the 820/Rambus implementation, but not on the 815E/PC133 SDRAM configuration.

Richard McCormack, editor and publisher of Manufacturing & Technology News, a scrappy weekly newsletter that has been chronicling the inexorable decline of U.S. manufacturing, has written a sobering article based on a Google Map tour of central Detroit.

The once bustling auto manufacturing capital of the world is now filled with deserted neighborhoods, with entire city blocks of homes bulldozed. The is the reality, a direct consequence of the offshoring of American manufacturing jobs.

Read McCormack's report here — and weep.

There is a paradox brewing in the layout of integrated circuit designs at nanometer nodes. IC design teams are choosing between layout automation vs. full custom design techniques.

While the automated layout tools seem fast, engineers may grow old fixing timing, power and yield problems on the back end of the flow. Meanwhile, full custom tools give designers more control over custom digital and mixed-signal circuit layouts, but the lack of automation can make project completion seem light-years away.

The nanoscale IC design paradox is that designers need both hands-on custom control and high-speed automation performance.

Generally, large IC designs are created using automated place-and-route (APR) tools. The larger the design, the more the speed and confidence of APR tools outweigh the potential compromises in area or performance.

Pioneer itself has not made any business plan with this technology. Rather, Pioneer is looking for partners to commercialize this technology,” the company spokesman said.

SANTA CLARA, Calif. — Here's a surprise. Benchmark test results from Intel Corp. show its new 815E chip set with PC133 SDRAMs beating the performance of its 820 chip set with Direct Rambus memories. Moreover, Intel has posted those unexpected test results on its Web site, not intending to show PC133 SDRAMs beating the Direct Rambus memory format, which is favored by the Santa Clara chip giant.

In nine of 11 standard industry benchmarks the 815E/PC133 synchronous DRAM implementation beat out the 820/Rambus configuration for desktop PCs. The two chip sets and different memory formats were about equal in three of those tests, according to results on Intel's Web site.

Intel was not intending to show a side-by-side comparison of those benchmark results, but instead was attempting to promote the performance of its two chip sets and the different memory formats in separate sections of its Web site. But the benchmark test results were discovered and matched up by an Internet user, who then informed SBN .

Intel used its 933-MHz Pentium III processor in testing both of its chip sets for PC133 SDRAMs and Direct Rambus DRAMs, which are based on the architecture from Rambus Inc. of Mountain View, Calif. Matching up the data from the same 16 benchmarks shows the 815E/PC133 implementation winning in the overwhelming majority of tests, as shown in the table below. The test results can be accessed from Intel's Web site at: http://www.intel.com/procs/perf/PentiumIII.
