PCMark Vantage Tests

PCMark Vantage is an objective hardware performance benchmark tool for PCs running 32- and 64-bit versions of Microsoft Windows Vista or Windows 7. It's well suited for benchmarking any type of Microsoft Windows Vista/7 PC: from multimedia home entertainment systems and laptops, to dedicated workstations and high-end gaming rigs. Benchmark Reviews has decided to use a few select tests from the suite to simulate real-world processor usage in this article. Our tests were conducted on 64-bit Windows 7, with results displayed in the chart below.

* EDITOR'S NOTE: Hopefully our readers will carefully consider how relevant PCMark Vantage is as a "real-world" benchmark, since many of the tests rely on unrelated hardware components. For example, per the FutureMark PCMark Vantage White Paper document, Gaming test #2 weighs the storage device for 100% of the test score. In fact, according to PCMark Vantage the video card only impacts 23% of the total gaming score, but the CPU represents 37% of the final score. As our tests in this article (and many others) have already proven, gaming performance has a lot more to do with the GPU than the CPU, and especially more than the hard drive or SSD (which is worth 38% of the final gaming performance score).


The TV and Movies suite concentrates on video playback and transcoding, but only uses two threads at a maximum, so performance here is based more on clock speed and IPC (instructions per clock) than anything else. Here we see one of the closest performance clusters of this review, with the overclocked 3960X only 38% faster than the FX-8150 and 8% faster than the 2600K.

The Gaming benchmark relies on the hard disk and video card for over 50% of its score (see the Editor's Note above), and we're using the same HDD and video card for all platforms, so the Intel decisive win in this test simply means that Vantage's gaming code is more optimized for Intel processors. Bear in mind, however, that most "real world" games will not show this difference; generally, in games, your video card matters most, followed by the clock speed (not number of cores) of your processor. The PCMark Vantage gaming test can use up to 16 threads, so it's very strange that the eight core FX-8150 turns in markedly lower scores than the four-core Intel processors, even considering Hyper-Threading.

Unlike the Gaming test, the Music test results have more real-world relevance, since multi-threading is much more common in music transcoding applications than it is in games. Even so, the advanced Sandy Bridge cores mean that the four-core i7-2600K beats the six-core i7-980X. The 3960X wins again, albeit not by much.

The wins are piling up in the Intel column. Let's move on to CINEBENCH.

This says it all for me:

"For most of us, though, the Core i7-3960X makes as much sense as a 1,000 horsepower street car. It's fun at the dragstrip (running benchmarks), but a Core i7-2700K on a nice Z68 motherboard will be a fraction of the price and just as fast in "real world" terms."

This is a new era in power that will remain almost completely unused and unnecessary for most people, like you say, even us enthusiasts will need to think twice, except those who have money to needlessly burn.

You would think in these economic times, R&D of high dollar items like this would slow down. Interesting. At the same time, my i7 920 cost 1000.00 back in 2008, so the price to power ratio has dramatically fallen too.

Doug, the Core i7-920 was (I believe) $279 at introduction. It was certainly nowhere near $1,000. Are you talking about your complete system?

Opps, no you are right; The 920 was the lower end that you could OC and get 960 performance from, or better. I think the top end was 960 back then. In any event, the price stays the same for the top end and the performance gets better.

I think that this platform and some of it's future iterations will dominate for the next couple of years. They've hit one out of the park with this.

Depends on what this means "hit one out of the park" -- and what "dominate" means if you mean "make money for Intel", consider that Intel's ee chips are about 0.005% of their sales, and in the big picture of comparisons you could easily say that almost no one buys these, nor needs these, when a $150 fusion or SandyM proc is satisfying most people's needs.

But rich fanbois have big egos to satisfy so there will always be market for for stuff priced way out of line with what it is really worth. Useless - if I'm paying $1000 for a CPU it better be a multi CPU server chip in a render farm - something where you can get a return on your money at least. just my 2 cents for an alternate perspective.

# RE: depends ...theUglyMan0war 2011-11-15 06:42
because egos get stroked when you mention the size of yer renderfarm?
I think petty envy speaks always more to one's ego state. Anyone's needs that are "really satisfied" by todays computing power will probably have a "cute device" for their "cute needs" soon enuff. and good riddance.
My needs are far from even close to being satisfied... though cinebench over 12 is at least progressing ( not enough knowing the Ivy Extreme will be released in 2012. And hopefully that benchmark gives more distance )

Catch 22 is really depressing! There is an army of artists whose talent could bring yer boss machine to it's knees given the chance. Instead they compromise to console greed economics. And instead of buying hardware that can push the boundries a market without that entertainment actually believes that we are at "good enuff".

Thanks for the consolitic ball and chain!

Buy it and they will make it/ Make it and they will buy it.

What do "most" users do with their computers that does not desperately need more computing power? Don't they have an app for that yet?

I'm sorry to say,but this review is a little stupid.The majority of the people buying this platform are not going to be able to buy a 1000.00 dollar cpu.What you should have reviewed and what most people wanting to build a new setup want to see is the 3930k compared to the 2600 or 2700k.It makes much more sense to buy a 550 dollar 6 core oc it and cook along than buying a 1000.00 6 core which probably only has a minimal increase in performance.I can tell you I would rather build a system with a 2600k if fps's are higher than building one with the 3930k.But we don't know the answer to this question because you decided to review the new hot rod that no one can afford.

Hmm... I'm leaning towards stupid reader here. If you're shopping for a Kia you don't start reading Ferrari reviews. My point being that this particular article obviously doesn't match your needs, and nobody forced you to read it.

Also, if by FPS you're referring to frames per second, I suggest you do a bit MORE reading here at Benchmark Reviews... so you'll learn that the CPU has very little to do with frame rates.

I think when everyone has bought their idevices it will be alot better. Computers will be sold to people who need computing power again. And articles will simply be written for a market that needs that power.

# litte harshTechman 2011-11-14 13:45
I know the cpu only minimally increases frame rates but when your building a high end gaming system every frame counts and some games are more cpu dependant.Your going to get better frames out of a system with a 2600k and a 590 over a system with a 8150 and a 590,other specs the same of course.I do admit I was a liittle harsh,sometimes these companies send you whatever they want,not what you request.I think intel should be strung up by their toes,I'm tired of this greedy monopoly they have,but thats also amd's fault for not handling their end of things properly.

After working night and day for a full week to produce several deep-tech articles for the launch, we tend to take destructive criticism personally. Add to this that David and I both worked through illness to meet the deadline, and well, let's just say we hope to get paid for our extra efforts in constant praise. We cross our fingers, but...

Look on the bright side: now that Intel's Core i7-3960X has significantly raised expectations, you might soon find AMD processors selling in the blue-light section over at K-Mart. I understand they fired their entire marketing staff of 1400 workers after Bulldozer launched, so the only people saying anything good about them these days are the fan boys, and even they're unhappy.

You're right about frame rates with some games, and I over-simplified my statement. Battlefield 3 is one such game, and DirectX-11 effects drive all processor cores to nearly 50% usage even when played with a GTX 590. Obviously, there are times when the CPU will make a difference in game performance, but that requires advanced technology at a time when most developers are keeping to console (a la Modern Warefare 3).

What about readers who have a different set of criteria than you, say systems managers wanting to get the most power for a large (or smaller) design company? What about the person who is thinking about buying the 2600, but wants to know how it stacks up against the best? What about a review site that doesn't test the latest and the greatest? What about, actually, trolling?

This was a very comprehensive review. It left me with no questions about the comparison of power.

# Good review - thanks for the infoRodriguez 2011-11-14 15:24
The inclusion of the SPECapc Lightwave benchmarks in your reviews is awesome. Really helps put things in perspective. Thank you.

For example, my 2600K at 4.9Ghz + water can run the SPECapc rendering suite in 443 seconds. From your chart in the review it shows an overclocked 3930X does it in 408 seconds.

Simply put, that would be a 10% improvement from what I have now for a 300% price tag. :-)

# RE: Good review - thanks for the infoDavid Ramsey 2011-11-14 15:30
Yeah, SPECapc Lightwave doesn't keep all of the cores going all the time. Back when I reviewed the 2600K, I got 519 seconds for the rendering suite for a 2600K running at 4.7GHz, but that was with an NVIDIA GTX 280 video card rather than the Radeon 6850 I was using this time around, so the results aren't directly comparable.

# RE: RE: Good review - thanks for the infoRodriguez 2011-11-15 10:20
Hmm, well I only test the rendering suite and my cores stay pegged once each scene is loaded and rendering begins. I can get pretty consistent results between 440-445 seconds at 4.9G. Also, at a couple of suicide runs that I knew weren't stable at 5.0G, it completed at 431 and 433.

I just wanted to say the fact you include this test in your reviews is very helpful to me, so thanks again. :-)

# RE: Good review - thanks for the infoDoug Dallam 2011-11-14 22:11
But if you multiply that 10% over X employes by X renders per day over a year, it might far make up for the price of the CPU. Let's say a project, like a modeling program, takes 10 minutes to complete every run. That's 1 minute each run time saved. If you do 120 runs in 24 hours, that's a total time savings of 2 hours each day? If you can run everyday, that's an extra moth of time each year.

So yes, you pay 300% more, but that is a one time cost compared to getting that 10% every single time you run a model.

I wonder how ivy bridge will perform against sandybridge. Which is out soon! The extreme sandybrdige chips are out almost 2 years later than westmere extreme chips. The perfomance gain is expected.
I believe the 3d ivybridge will be a better bargain than these.

Idont know if ivybridge extreme will be compatible with x79 mobo but P67 mobos will all for ivybridge upgrades making the 2600k chips a better deal from the getgo.

Just saw the following:

Still will probably wait for ivy bridge - E as the cinebench numbers do not justify dropping $1500 for x79 porn. But if the 3 way scaling is even close to the truth then I am very happy that the IVY Bridge solution will most likely do as much.

Makes waiting a few more seasons for my new dragster pretty hard though.
