3 / 4 page Benchmark Tests Demonstrate Improvements in Performance and Performance-per-Watt Dual-core LV and ULV processors versus single-core LV processors The Dual-Core Intel® Xeon® processor LV 2.0 GHz can provide a greater than 2x performance gain, and the Dual-Core Intel Xeon processor ULV 1.66 GHz can provide a greater than 1.9x performance gain, compared to the single-core LV Intel® Xeon® processor 2.8 GHz (see Figure 2). Due to lower thermal dissipation, the Dual-Core Intel Xeon processor LV 2.0 GHz can deliver a 4x improvement in performance/watt, and the Dual-Core Intel Xeon processor ULV 1.66 GHz can deliver a 7.1x improvement in performance/watt, compared to the single-core LV Intel Xeon processor 2.8 GHz (see Figure 3).

(Dual-Core Intel® Xeon® Processor LV with Intel® E7520 Chipset Development Kit). • Two Low Voltage Intel Xeon Processors with 800 MHz System Bus, Intel E7520 Memory Controller Hub, DDR2-400 MHz, 8 DIMMS, each with 256 MB memory. (Intel® Xeon® Processor with 800 MHz system bus, Intel® E7520 Chipset, and Intel® 6300ESB ICH Development Kit). Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Intel product as measured by those tests. Any difference in system hardware or software design configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing. For more information on performance tests and on the performance of Intel products, visit http://www.intel.com/performance/resources/limits.htm 2 SPEC CPU2000 benchmark tests reflect the performance of the microprocessor, memory architecture, and compiler of a computer system on compute-intensive, 32-bit applications. SPEC benchmark test results for Intel microprocessors are determined using particular, well-configured systems. These results may or may not reflect the relative performance of Intel microprocessors in systems with different hardware or software designs or configurations (including compilers). Buyers should consult other sources of information, including system benchmarks, to evaluate the performance of systems they are considering for purchase. For more information about SPEC CPU2000, visit http://www.intel.com/ performance/resources/limits.htm 3 Performance/watt reflects the Spec CPU2000 benchmark test results (as described above), divided by Thermal Design Power (TDP) for the respective processors. For the Dual-Core Intel Xeon Processor LV 2.0 GHz, TDP is specified at 31W. For the Low Voltage Intel Xeon Processor with 800 MHz System Bus, TDP is specified at 55W. 4 Intel branded product name for “LV Intel Xeon Processor 2.8 GHz” is Low Voltage Intel Xeon Processor with 800 MHz System Bus.
