updateBroadwell-E Supports Intel Turbo Boost Technology 3.0

[guskline]

csbin: Another excellent find. It will be real interesting to see a stock 6950x against a 5960x and see all of the performance increases in addition to 2 extra cores.

Should be an exciting read.

Interesting. I would imagine Turbo is done via firmware, so updating older CPUs to include this feature may be viable.

I doubt it. Traditional turbo works off the number of active cores where any core can run at the maximum turbo if the other cores are idle. Turbo 3.0 suggests all cores are not equal with some able to run faster than others but not all at the same time. IOW there is still only one used core frequency and voltage at any given time.

Seems to me this app gets the dispatcher to schedule on the faster cores when there is some idleness.

Will Intel start binning and charging by the highest TB3 speeds of cores?

Could you you have 10 core BWE chips at the same base clock, with different turbo speeds, for different prices?

No.

Indeed, they are already too fragmented. Seriously why dozens upon dozens of CPU variations? Then bad things happen: they must be already facing issues having some Broadwell-D and EP parts so close to each other, some with more cores and slightly less speed etc. Pricing wars among themselves lol.

Yea, I have said it before. Intel's lineup is entirely too fragmented. Much like the USA automakers is the 80s, way too many models that increased costs and confused the consumer. Eventually, GM cancelled 2 entire model lines, if I recall correctly.

Three actually: Oldsmobile, Pontiac, and Saturn. Though Saturn was supposed to have been sold rather than eliminated outright . . . it's effectively dead in any case.

Yea, forgot about Saturn. I was thinking of olds and pontiac.

"On the horizon is Broadwell-E and I can assure you now these do not share the same characteristics as the Broadwell-C parts

We will have a new toy to play with as MSR199 capabilities becomes known.

FUGGER"

broadwell-e =/= broadwell-c


MSR199 = Turbo 3.0

Today at 10PM PST NDA is lifted for broadwell-e. Benches and reviews should go up tonight

"TB3.0 is like process lasso, you tell it what process to watch for and it will boost that process on the fastest cores.
When you load TB3.0 software it will tell you in order of quality each core is, highest first.
Yes, this is the order listed in BIOS.
We can now adjust each core speed independently, but the vcore is constant across all cores still.

Once you find your fastest cores you can turn those up and direct processes to them. - Fugger"

 

[DrMrLordX]

Hmm, so there's an external software component as well? Interesting.

Just sets affinity for each process accordingly I would think. I doubt cores will be operating at different frequencies at the same time and cores have been individually ratio programmable since core 2. The only time that could be done AFAIR was with the core 2 quads which actually comprised of 2 bridged dual cores.

Easy test would be to run a real time single thread on a slow core and see what happens, perhaps TB3 will spit the dummy and give up

Due to FIVR, Xeon E5 v3 and Xeon E5 v4 have a feature called "Per-Core Frquency Scaling". So that's just an extension to that.

If you've read anything I've posted in this thread, including linking official intel slides, you would already know you CAN operate cores at different frequencies. Its official. Thats the whole point of it. Thanks for the insight though

Well unfortunately or luckily I don't believe everything I read.

See : http://www.intel.com/content/www/us...y/turbo-boost/turbo-boost-max-technology.html

A Frequency Boost to Get More from Your Processor

Intel® Turbo Boost Max Technology 3.0 doesn't replace Intel® Turbo Boost Technology 2.0. It enhances it with a massive frequency boost on your fastest core for even more flexibility to get the best from your processor.

Factors that Impact Intel® Turbo Boost Max Technology 3.0

Availability and frequency upside of Intel® Turbo Boost Max Technology 3.0 state depends upon a number of factors including, but not limited to, the following:

• Type of workload
• Number of active cores
• Estimated current consumption
• Estimated power consumption
• Processor temperature
• Drive support

So you can enjoy TBM with single threaded apps but start activating those other cores and core frequency will drop, including the faster cores. Only one frequency at any point in time.

- He is excellent at stirring up an a vs b fanfest-riot, either totally intentional or just very passionately on the subjects. You can disagree with your opponent without going out on that limb, a wise man once told me that the more you disagree with some one the more you should approach with courtesy. One way or the other I know i enjoy reading threads alot more without the a vs b crap all around (and I am perfectly able to filter out the pro amd/whatever biases on my own, you dont have to call em all out as a matter of civil duty on my account!).
