re: http://www.garlic.com/~lynn/2013b.html#5 mainframe "selling" points IBM publishes 50BIPS for 80-way z196 past post in ibm-main from last fall http://www.garlic.com/~lynn/2012l.html#59 quoting benchmarks numbers from this web page http://www.istorya.net/forums/computer-hardware/485176-intel-xeon-e5-2690-and-e5-2660-8-core-sandy-bridge-ep-review.html (Dhrystone) E5-2690 @2.9GHZ 527.55BIPS E5-2660 @2.2GHZ 428.15BIPS X5690 @3.45GHZ 307.49BIPS i7-3690 @4.78GHZ 288BIPS AMD 6274 @2.4GHZ 272.73BIPS (Whetstone) e5-2690 @2.9GHZ 315GFLOPS E5-2660 @2.2GHZ 263.7GFLOPS X5690 @3.4GHZ 227GFLOPS i7-3690 @4.78GHZ 176GFLOPS AMD 6274 @2.4GHZ 168.11GFLOPS ... aka the e5-2600 at 527.55BIPS is also capable of 315GFLOPS and from this recent post http://www.garlic.com/~lynn/2012j.html#34 in "Mainframe Experts" discussion http://lnkd.in/QhQ73A including ibm results for lots of platforms (at the time as of 3july2012 ... now current as of 29Jan2003 ... IBM currently has 873 bencmarks listed in the following ... none of them for mainframe) http://www.spec.org/cpu2006/results/cint2006.html risc chip/processors have had numerous performance features for the past several decades that provided them with significant throughput advantages over i86 chips. however, for the past several generations of i86 chips, they have moved to risc cores with hardware layer that translates i86 instructions into risc microops ... significantly closing that throughput gap. z10 was rated at 30BIPS with 64processors or 469MIPS/processor. z196 is rated at 50BIPS with 80processors or 625MIPS/processor. The description is that much of the improvement in z196 per processor performance was introduction of some of the features that have been in risc processors for decades (and are part of all the latest i86 processors). zEC12 is rated at 75BIPS with 101processors or 743MIPS/processor ... with claims that there have been some additonal risc-like features in the way the zEC12 processors operate. Part of the claim for the rapid advancement in i86 chip throughput is there being competition between multiple vendors of i86 chips. for other drift ... this ibm-main post references peak i/o throughput benchmark for z196 using 104 FICON channels and 14 system assist processors that achieves 2M 4k IOPS (although peak SAP all running at 100% is 2.2M and recommendations is to keep SAP utilization below 70% or 1.5M) http://www.garlic.com/~lynn/2012m.html#4 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee FICON is an enormously expensive protocol layer on top of FCS, that is significantly slower than the the throughput of the underlying fibre-channel standard technology. Above post reference announce of a *single* FCS channel (aka technology used in FICON) for e5-2600 capable of over 1M IOPS (two such FCS channels could give an e5-2600 the same throughput as z196 peak i/o throughput with 104 FICON channels). other recent posts here in ibm-main mentioning e5-2600 comparisons http://www.garlic.com/~lynn/2012l.html#20 X86 server http://www.garlic.com/~lynn/2012l.html#28 X86 server http://www.garlic.com/~lynn/2012l.html#30 X86 server http://www.garlic.com/~lynn/2012l.html#34 X86 server http://www.garlic.com/~lynn/2012l.html#51 Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012l.html#56 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012l.html#81 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012l.html#87 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012l.html#88 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012l.html#90 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012l.html#100 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012m.html#3 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012m.html#5 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012m.html#43 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee http://www.garlic.com/~lynn/2012o.html#25 Blades versus z was Re: Turn Off Another Light - Univ. of Tennessee -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
