Just because you doubnle the core count does not mean performance is doubled.
I assume that is where architecture comes in?

post #24 of 195
seeing how fast the current AMD x6 is...
adding 2 more cores and an upgraded architecture i can see it being faster than an i7 easily. Iam sure Intel will always dominate but as long as AMD can pull of a good competitor with some serious horsepower, iam moving over to AMD. Like the other user said, i dont like the direction Intel is taking. Power to disable sandy bridge via 3g, overclocking on the new 2nd gen i7s are a joke unless you have a K series. Thats too much control, and their massive support for cloud computing and government contracts and internet Id support. I HATE Intel.......

4 modules, 8 cores, 8 threads(As seen by the OS) that is faster than Intel's 1 module, 4-core, 8 thread CPU.

50% faster than 950 puts it right at or slightly a head of the 2600K. So its essentially Bloomfield v. Thuban all over again.

The question is, does AMD have a response to Intel's enthusiast platform?

the way intel implements its SMT is different than the way AMD put it into Bulldozer.

for intel the all of the threads are forced through a single pipeline which nowadays doesn't really give you much performance boost. 1 virtual core in intel processors does not equal one real core.

in bulldozer there is 2 separate pipelines for threads and instead they share the floating point unit. its a more open approach that should give more performance to the second "virtual core" made by multi-threading. I believe amd calls it CMT (cluster multi threading). AMD claims the the "virtual" core can have up to 80% performance as the real one, with only a 5% more die space.



So yea Bulldozer will do what its name says. There is also a rumor that AMD is bringing back the FX name for the Bulldozer so you know it will be very competitive if not better.

My dilemma will be....get a AM3+ mobo and bulldozer

or wait for AM4 boards and just get a Phenom II X6 this year

Ok what alot of you are failing to remember is that hyperthreading = die space to implement, so as far as i understand, AMD takes die space and packages 2 processing "cores" as one "module" that shares resources. Thus you take the die space and make it slightly more efficent, and thus in heavily multi threaded and optimized you might see better performance than when compared to simply 4 cores hyperthreaded.


What i think we will see this time around is AMD leading in multi threading, while Intel takes the single threaded crown.
