Anyway, mine isn't terribly above average. 4.7GHz is usually reachable if you have proper cooling. Water cooling works wonders. Unfortunately, to get "proper cooling" a delid is necessary. (Boo hiss Intel)

Yea 3770k and u get the extra threads..

Are those threads even useful for gaming?

is it so hard to make a proper scheduler to work? 8 threaded workloads would yield zero performance increase as expected but 2-4 threaded apps should;ve had an increase. maybe it's already fixed with the patch on windows 7

nope. even with my i7 950 a few years ago I disable HT and settle for higher overclocks coz it doesn't help at gaming at all and sometimes becomes a performance hit in some games. with that said I'm thinking of getting an i7 3770k. I miss my 8 threads frown.gif (even though I have zero use for it lol)

One thing I'm unclear about with hyperthreading...
Say threads 0 and 1 are running on physical core 0. If the game is not using thread 1, will thread 0 have the same performance as core 0?
What I'm saying is, is there a "load-balancing" effect? If one thread on a core is being used but not the other, will it have the same performance as one physical core with HT off? Does the power from the unused thread transfer over to the used thread, or are they stuck at 50-50 no matter the load on either?

Sorry, it was difficult to word that question properly

hyperthreading is rather complex, afaik it automatically disables when you're in a lightly threaded workload to avoid performance hit. the reason why even with two threaded apps like games you still get how "2 cores" would give not "2 virtual cores" that hyperthreading does.

Interesting. Well, I guess that a 3770k could be useful in games that can use 6 threads (can't Far Cry 3 do that?) and for the higher binning. I can't decide if it's worth my money at the moment. Probably not.... maybe I should just wait for Haswell.

I think I worded that horribly but I'm not really far off imo. hyperthreading isn;t perfect and in some games it really does give you a performance hit rather than an increase. if it's a dedicated gaming pc an i5 is the best. not to say the i5 is a slouch in heavy threaded workloads. it's still a beast

It is useful for more than 4 threads, such as BF3 multiplayer. All hyper threading does is jam more requests down the pipeline for the cores to process. It is around a 30% boost in performance in comparison to 4 cores if you can utilize the 8 threads. It has been around long enough that there is rarely a case where it hinders you (improper software tuning has mostly been ironed out). Anything that only uses 4 threads, a 3770k will be roughly equal to a 3570k. In 8 threads it will be about 30% better.

It is one of those things that also shows how poor the AMD cores are. The AMD modular design is much better than hyperthreading. You get about 80% of 8 full cores where hyperthreading you only get about 30%. Even with that 50% difference on the architecture, it still trails in a lot of ways.

Think i proved they were.. if the game uses the 8350 extra threads it will also use the 3770ks extra threads.

If you seen your clock for clock bench vs the 8350..

Now see a 3770k bf3 clock for clock vs 8350.



I also have my own tests,
Warning: Spoiler! (Click to show)












Any game that uses extra threads gets more out of a 3770k.
