Evil ICC engineers

Sounds like the intel compiler folks found a way to fool the benchmark by bypassing a whole lot of instructions.


This is nothing new with intel compilers. They seem to have an army of engineers making specific release for specific benchmarks.


All is fair in love and benchmarking?

I agree with your point about mobile phone users not giving a hoot what kind of processor their phone is running. Obviously there are some that do, many of which read EE Times, but the vast majority of people buying smartphones could care less.

Oh, I can see end-users caring about benchmarks.  I just don't think most will use  them to make a purchase decision.  They will use them to validate the decision they already made.  The AnTuTu bechmarks are the sort of thing I can see a smartphone owner point to and say "Look how much better the benchmarks are for the phone I bought than they are for your choice." (with the implicit sub-text "I made a better choice than you did, so I'm smarter and cooler than you.")

And I can see cases in the industry where benchmarks will be used, and there will even be agreement they should be used.  I just hope for better understanding of what the benchmarks measure, how they measure it, and what the results actually mean.  (This may be wishful thinking on my part.)

I also wonder how many mobile device users are really aware of what processor is under the hood, or cares if they know?  As you say, they are buying an eco system, and what is available in that eco system will be far more important than what that eco system runs on.  There are probably device owners who are aware that Intel and ARM are battling for share in the mobile device market, but I really doubt anyone will say "I'm running ARM, and you're running (yuck!) Intel!  You're a real dweeb!"

Your point is well taken and I completely agree. End-users don't care about benchmarks. PC generation and pre-PC generation users usually look for common brands and features that they prefer. The mobile generation looks for something new. Benchmarks really come into play with the OEMs and carriers that are making decisions about what technology and products select. So, they still play a role within the industry, even if we all agree that they should not.

And, when we really look at an ARM or Intel processor, the decision is very similar to selecting the OS - what ecosystem do you want? Because, a processor alone does not make a successul product.

Jim, it seems as though you kicked up a hornets nest and forced AnTuTu to take another look at the benchmark. This is an example of great analysis that apparently caused action. Kudos to you Jim.

Great Post. Fantastic to see that EE Times article was influential enough for Antutu to update their benchmark, though it does cast doubt on the value of traditional benchmarking. Also a great lesson not to 'follow one number' to judge the capability of a smartphone.  I'm sure Intel isn't too happy about such a post, so kudos to EE Times for sticking with the facts/data.

There are two target audiences for benchmarks: engineers and end-users.

Engineers have price/performance targets they want to meet when designing systems, and benchmarks are metrics that tell them where they are on meeting the targets.

End-users will see benchmarks as ways of comparing systems.

But in the smartphone market, where the AnTuTu bechmarks seem to be popular, the question is what decisions are made on the basis of them.

Smartphones are better seen as fashion accessories than as tech.  Most buyers are interested in cool.  Smartphones are status markers, and the incentive will be "My phone is cooler than yours!" 

What makes a phone cool?  Brand will be critical.  iPhone buyers aren't buying iOS, they're buying Apple.  There are scads of Android phones, so while Android is cool, it's a common denominator, and just running Android is not a deciding feature.  Windows Phone is not cool, and that may be the biggest challenge Microsoft and Nokia have in getting a share of the market.

The smartphone market reminds me of the movies.  In the movie business, you are as good as your last hit picture, and if your studio hits a dry patch and doesn't have hit pictures for a while, you may go out of business.  The smartphone market is similar.  Motorola had a hit with the Razr, didn't have a followup hit, and was rumored for a bit to be looking at getting out of the smartphone business.

I'd bet that most folks who run the AnTuTu benchmarks are measuring performance on the phone they already bought for other reasons, and aren't making a decision on which phone to buy based on them.

Given that, how much should anyone care what the AnTuTu benchmarks say?
