No i'm not high either... wink.gif

I enjoyed. biggrin.gif

Today has made me third guess myself. First, when BD came out I was like "oh, i'm going Ivy". Then this story came out and I'm like"Yeah! I can get a BD". Finally, the whole 77w tdp thing came out for Ivy and now I'm like "Oh no, a hard decision!" Either way, this is very good news/rumors.
It. Gets. Better.

Funny that the pre release stuff for BD with extremely credible sources were deleted almost instantly, yet, this article is a no name website with NO source within the article what so ever, and is allowed to be posted in the news by a moderator. smile.gif

Does this fix solve the huge power usage problem though?

I agree with this. Everyone called shens on the bad benchmarks, I'm calling shens on this.

Here is my current understanding:

In the past we have seen CPU drivers for windows (mostly XP, and mostly AMD.) This is NOT what is occurring here, its not some weird issue with the processor causing it (although it kind of is)

What is happening is this: The FX 8xxx series of processors has 4 cores, each core with TWO integer pipelines, effectively granting two processor cores for the price of one. (not "hyperthreading" effective, but almost literally additional core effective.)
This is all fine and dandy, except that when Windows (or Linux) goes to issue work to a core in the processor, it picks the core with the least load, and distributes things using a task scheduler. The problem here is that when a single pipeline on a bulldozer core is being utilized both cores are effectively "in use" even though Task Manager sees the cores appropriately, the task scheduler does not. This isn't really anybody's fault, but rather an oversight.
Standard CPU design from a by-the-book standpoint would never add a second integer pipeline to a single core. So nobody ever really thought to code a task scheduler that worked in that situation. So basically, AMD thought outside the box, and Windows got confused.

Oh not to mention that if the scheduler tries to run non-integer work on one of the integer only threads, the CPU returns an error and the command is re-queued and has to sit in line waiting to be executed again. Basically its a scheduler issue, and could definitely cause some HUGE impact in synthetic benchmarks and normal use. And even more issues in a cluttered server environment.


that's what i get too.. great overview

This says its a registry fix for windows since windows 7 doesn't play well with 8 cores. Why don't people simply check performance in linux, linux loves cores.
