Smoke and Mirrors anyone?
Well, maybe we need to give IBM the benefit of the doubt since the webcast hasn’t even started yet and most of the launch materials have been released early. What I find amazing are the following!
1) VERY CONFUSING GHZ/cores/socket configurations between Power 770+ and Power 780+ - Time for a new decoder ring! How the hell do you figure out which is best for your workload? More work to feed the IGS folks!
2) The 8-core Power7+ chip runs at a slower clock speed than Power7 (3.7GHz vs 3.86GHz) but the 4-core Power7+ chip runs at faster clock speed than Turbo-core Power7 chip it replaces? (4.42GHz vs 4.14GHz TC). So much for 8-core superiority?
3) Only Power770 and Power780 systems have been updated-Wheres the rest of the product line or will we have to wait a whole year for Power7+ to be released across the product line?
- Theres no Power7+ DCM based systems, No improvements to blades, Power entry and mid range systems untouched-maybe next year?
4) Looks like Turbo-core mode appears to be DEAD!
5) Many of the benchmark results on Power 780 Power7+ were run with 4 cores/CPU or 6 cores/CPU and not 8 cores/CPU, hiding many of the scalability challenges of doubling cores per socket.
6) Theres no database benchmarks (unless you call SAP SD-2 Tier a DB benchmark), no TPC-C, TPC-H, no SPECjEnterprise2010, no Oracle SW benchmarks, no Sybase, No Peoplesoft, No Siebel, no Websphere, etc.
7) Theres no improvements to I/O / PCI-Express - no PCI-E Gen 3! IBM continues to use outdated PCIe Gen2, I/O backplane that was introduced with the model MMC.
8) And heres the kicker. While Oracle continues to get kicked on making benchmark claims, IBM isn't? when stating "IBM Lab testing"
Where are the public proof points on real world (new) benchmarks showcasing the 20-30% performance improvement claimed? Theres no OLTP ore Java enterprise results published so IBM cant prove these statements publicly. Publishing results on 6+ year old benchmarks is lame.
From IBM press release:
"IBM lab testing showed clients have a denser compute node with 20 to 30 percent per core performance improvement and the new POWER7+ processors deliver improved application performance. Expectations are as much as 40 percent improvement with Java based workloads and as much as 30 percent with traditional OLTP and ERP environments compared to POWER7"
