That's 3d Mark 11, it doesn't put any load on the cpu, except the combined test where your 8 cores are holding back your 5870.

Man, I'd hate to see what it looks like in vantage

Not hating, it doesn't really matter for most people - but it's the reason why *I* skipped out on AMD like a thief in the night.


Here is my gtx 470 at x8 (9800 gt in other slot)



You'll notice my gpu usage is going up, my 4 cores are driving the physx faster than your 8, this allows the gpu to work harder to match speed with what the cpu is doing.

If you run Vantage we'll see a huge bottleneck because the gpu portion of the test is single threaded, your x8 simply won't be able to push the 5870 100% throughout it.

you´re complaining about tiny part of synthetic benchmark ?

IMO, real gameplay is more important than some weir benchmark experience

--------
stupid vantage wants some key, anyone help ?

Request a trail key - http://3dmark.com/3dmv-trial?pcmVant...&dm05Results=0

It the only part of that benchmark that really mattered, the rest was all gpu bound.

Sorry to be rude, but i dont believe in those "benchmarks"..
Why ??
Because many of them are done through intel compiler, which is known "it hates AMD CPUs"

PhysX ? Same crap.. The CPU code part uses old/obsolete x87 FPU path.
It has been criticized, and discussed everywhere

OpenCL is future, it will run on any cpu or gpu, PhysX and Cuda are proprietary - they support only nVidia hardware


People who believe in those "benchmarks" are naive, these tests doesn´t reflect real world experience - performance.

One huge example: Cinebench shows big gain with SMT ON.. (intel compiler at work)
But if you look at results of x264bench - shows 8% performance loss with SMT ON..

SMT at gaming shows often 0% gains , (sometimes performance LOSS up to 5% )

Conclusion : real software (and wise developers) maximize usage on every thread their software uses..
But "legit benchmarks" of course does not, because ONLY unoptimized sofware can benefit from SMT

What does the red vs green mean?

I don't recall Vantage using all 6 cores for the gpu testing, or is that from the cpu part at the end?

It does what it needed to do, see those huge dips in gpu usage? Thats a massive bottleneck on a single card.


See how the usage never really drops compared to yours?

I'd like to see the x264 benchmark results to confirm that. With HT on, I get around 20~25% higher FPS when encoding. This is with real life use encoding recorded TV, DVD and Blu-ray rips with x264 (Handbrake).

There is a benchmark here: http://www.techarp.com/showarticle.aspx?artno=520

You should compare your own results with and without HT.

Balla, wait sec.. Just let me overclock MagnyCours to 5018MHz....
"Oh d.a.m.n." , i can´t ... :facepalm:

How many times i need tell you guys, that SB has NOT yet direct competitor ?
I see it´s futile, "intel-users-self-advertisement" is strong here .. Such disgrace
Just like many forums out there i´ve visited.


"SandyBridge for everyone"... Ha-ha, that´s funny
