SPEC launches standardized energy efficiency benchmark: SPEC launches standardized energy efficiency benchmarkGreat Article, George.Validates what has been known for some time now. No need for any more made up metrics like ACP or other nonsense.Why are there no AMD fans posting? Could it be because Intel owns the power/perf crown?Yeah, I thought so.Why did SPEC agree...; Tags: Programming languages, server community, SPECpower, Java, Green500 List; Discussion threads 2007-12-17

Not just hot air: Some details on Dell's server thermal design: It takes a whole lot more than just a new multi-core microprocessor or even whiz-bang virtualization technology to create a greener server. A few weeks back, I wondered out loud exactly why Dell's latest PowerEdge M-Series blades were getting so much notice as a green option -- after having several...; Tags: Dell Computer Corp., Dell PowerEdge, PowerEdge R300, Servers, Hardware, Heather Clancy; Blog posts 2008-03-24
San Clemente chipset gives HP lead on energy efficiency: The January 30th 2008 batch of test results are in for SPECpower_ssj2008 energy efficiency benchmark and it looks like Hewlett Packard has claimed the energy efficiency lead with their newest low-cost 2U HP Proliant DL180 G5 server. The secret to their success appears to lie in the selection of the...; Tags: Hewlett-Packard Co., Power Consumption, Power Supply, Advanced Micro Devices Inc., Watt, Intel Corp., Chipsets, Semiconductors, Hardware, Components, George Ou; Blog posts 2008-02-01
Beware of rigged CPU efficiency study: Beware of rigged CPU efficiency studyProcessors are only part of the power problemsI support data centers for various companies. The real cost of server ownership is the power required for Hard drives, multiple complex controllers, and network switches. We have a mix of storage appliances, servers and SANs. we are...; Tags: Processors, Servers, NASA, Advanced Micro Devices Inc., Intel Corp., CPU, quad-core, processor; Discussion threads 2008-01-15
Beware of flawed CPU efficiency study: Update 2/22/2008 - I originally used the word "rigged" to describe Neal Nelson's study. My reasoning for using the word "rigged" was due to the fact that the test platforms used in Nelson's study painted an inaccurate picture. Nelson's study omitted two generations of Intel products while including...; Tags: Quad-core, Advanced Micro Devices Inc., CPU, Intel Corp., Neal Nelson, Processors, Semiconductors, Hardware, Components, George Ou; Blog posts 2008-01-15

SPEC launches standardized energy efficiency benchmark: SPEC Standard Performance Evaluation Corporation launched its first standardized energy efficiency benchmark SPECpower_ssj2008 this week which tackles something that the computer industry has struggled to define in recent years. With datacenter energy costs spiraling out of control, server customers have struggled to sort out the conflicting messages from technology vendors...; Tags: Performance, Java, Quad-core, Power Consumption, Server, Advanced Micro Devices Inc., Energy Efficiency, SPECpower_ssj2008, Servers, Processors, Hardware, Semiconductors, Components, George Ou; Blog posts 2007-12-14
