yeah but turbo mode doesn't really apply much when you're stressing all cores
Anyway, I could be completely wrong. The benchmarks will all be revealed all once it's released. I'm just saying, intel specifying the LINPACK score to measure GFLOPS is already a known benchmark in itself.
I hope it's 45+% faster....I just have serious doubts, at least with real-world CG rendering software.
I mean put it this way - with the last xeon upgrade, sandy-bridge was a major architecture improvement (like 25%) over westmere and increased the core count 33%. It managed to get cinebench scores of 38% higher over the older top chip.
This time the core count is increasing 25% more cores and a minor architecture improvement (7%). I'm not sure how that will get a 45+% higher cinebench score over today's top xeon.
And cinebench is generally considered to be about as linear as 3d rendering can get unlike a lot of modern scene files that utilize several single-threaded functions before multithreading kicks in.
That intel slide was released just last week, but it's true that intel could have created it long ago. Though it does include some very specific things about the new phi's which make me think it's fairly recent.
Speaking from experience, because I've been in situations where money was available to buy new hardware/software and I chose to wait a few months for the new chips or software version to come out. The money will find a way to evaporate. Someone else will need it, and it will slowly get chipped away at. Also just how businesses are ran with their fiscal year and tax deductions - the business wants to recirculate the money ASAP for tax deductions. Holding onto it is too expensive in the long run.
We still don't know if the chips really will be available to the mass market in 2 months. Probably some vendors will have them and will be updating their BIOS's for their workstations and then just like apple has said, will ship by the end of the year. You'll probably be able to buy the chips themselves online in a couple months, but I wouldn't automatically assume workstation vendors are going to be shipping the new systems to your door in 2 months. Most vendors don't do preorders for new systems before they're ready to ship, but who knows.
