Smarter Scheduling ups Dozer win7 performance 10-20%  

post #1 of 131

Quote:
"The initial reviews of the first Bulldozer-based FX processors have revealed the chips to be notably slower than their Intel counterparts. Part of the reason is the module-based nature of AMD's new architecture, which requires more intelligent thread scheduling to extract optimum performance. This article takes a closer look at how tweaking Windows 7's thread scheduling can improve Bulldozer's performance by 10-20%. As with Intel's Hyper-Threading tech, Bulldozer performs better when resource sharing is kept to a minimum and workloads are spread across multiple modules rather than the multiple cores within them."
a lot of us told that as optimizations became available, full power of the chip would start to come out. but foresight is not something that is in abundance in people ...

Let's see here...

It won't help single thread performance.

It won't help fully saturated core performance either.

What it does is increase lightly threaded performance, but 10-20% is not going to change anything. The i5-2500k still trades blows with the 8150 for less when eight cores are used, and is faster in gaming.

The 8150 needs a major price reduction, it's a sub $200 chip.

wow. you jumped in at FOUR minutes.

................................................

answer the below :

did optimization increase dozer performance, or not ?

no.

dont answer. the question was rhetorical.

we told you people that as software optimizations became available, true performance of the chip would start to come out.

an optimization became available. performance of the chip got better. period.

Still about 50% shy on all-around performance until I'd consider buying them, at least for their current prices.

Let's see:

FX-8150: $279.99
2600K: $319.99

FX-8120: $219.99
2500K: $214.99


Certainly a tough sell for FX at those prices.

So what? 100% load performance shouldn't change and single threaded performance won't change. So why are you making a big deal out of this?

Because while everyone way saying it wouldn't matter, he was hearing it won't happen... He's trying to say he was right all along, while ignoring the fact that it still doesn't really matter.
