Windows 7 Optimized for HyperThreading

Speaking of "power management", I just installed Win 7 RC last night. Much to my surprise, the vanilla install does some default power management things I didn't much care for.

By default, my Desktop PC was set to "Balanced", was set to SLEEP after 20 minutes, and the CPU was set to throttle itself before increasing fan speed ("Passive Cooling").

I had to manually configure it to "Active Cooling" so it would increase fan speed before it throttles the CPU, had to manually setup a Performance setting, and turn off all the SLEEP and Hybrid Hibernation settings. Hopefully this isn't what Microsoft and Intel conspired to set up and call "power management".

Reinstalled Age of Conan, and left my PC on overnight to let it download it's 3GB worth of updates. Much to my surprise, my system was off in the morning, and had never updated (thanks to the default Sleep setting).

I think that they mean they recognize when a core is virtual, and schedule jobs accordingly. Before Ht cores just showed up as regular cores, and probably weren't tasked appropriately.

I.e. maybe now they can reduce the number of active cores by sending background tasks to the virtual HT core of an already active real core. Rather than use two physical cores, they can use only one, reduce power consumption. If that's the case, this is a good thing (now AMD needs to add them in).

It might also mean they won't send your video games or rendering software to HT cores knowing they aren't as efficient as real cores.

If Microsoft just means they can use all 8 cores (real/HT) of the Core i7s, I'm not impressed.

Microsoft has supported HT cores since XP. Anybody could see this with their old P4's w/ HT. I'd see two cores under CPU cores with XP and my old Northwood P4.

Nothing wrong with M$ optimizing the OS for a processor, but I was under the impression that this was common sense and not newsworthy.

Are we supposed to get excited because M$ improved its threading?

well lets all compare this to vista lol the excitement is rising and MS is finally optimizing the os and actually imnproving it

I want to hear the story(s) of MS working with AMD to optimize MS' operating system with THEIR processors.
One of the biggest headaches I encountered was when I upgraded a clients computer with XP SP3 and found it would not boot period. Came to find out that an INTEL power management driver got in there, which confused the AMD Sempron machine. Is it that hard to NOT have an Intel driver install on an AMD build?
Still... I do enjoy seeing cooperation between hardware and software.

I think its good, it will give people the power they need. I think it makes a lot of sence, to get stuff worked out now, so people wont have to download all the stuff later, I sure hope they will work out all the bugs =)

Finally, m$'s toy O$ has (proper?) support for a pentium4 feature...
[citation][nom]M. Yam[/nom]... contains optimizations to take advantage of HyperThreading (and we’ll assume that will also apply to any system with multiple cores).[/citation]
You assume wrong. HT can take advantage just if the instructions, in the alternate streams, are destined for different execution units, unlike "real" multicores. If the instruction streams are contending for the same resources, it's just getting worse.

It's not called wintel for nothing... monopolies stick together.

Mr. Yam, quit m$ a$$ licking ("ohhh, it's so yummy"), you're getting really pathetic lately..

I want to see Win7 know the difference between two physical cores and two HT cores. I don't want two threads running one one core while three other cores idle. Use cores 1,3,5,7 before using 2,4,6,8 HT.

As far as I know, there aren't any big updates for Win7 RC. It was probably just the "test" updates as seen in this article: http://www.tomshardware.com/news/windows-update-testing-release-candidate,7768.html

Hyper-threading, is like driving a car and texting at the same time. If you disable it in your bios, 90% of your PC problems will go away.
