Puhelimien ja tietokoneiden testisovellusten valmistajan Futuremarkin tiedotteen mukaan Huawei Ascend P7 vääristää nopeustestien tuloksia yläkanttiin niinkin paljon kuin 28 %. Kyseessä on tekniikka joka perustuu testisovelluksen tunnistamiseen jonka pohjalta laite ylikellottaa itseään ennen testin ajamista. Tästä johtuen Futuremark on poistanut Ascend P7:n tulokset tietokannastaan.
Alla Futuremarkin tiedote asiasta:
We have removed the Huawei Ascend P7 from our 3DMark benchmark performance rankings for breaking our rules governing benchmark detection and optimization. It now appears delisted and without a score at the bottom of our 3DMark Best Smartphones and Tablets list.
Our commitment to providing you with benchmarks you can trust means that:
We have delisted the Ascend P7 because it does not comply with our rules. Specifically,
“The platform may not detect the launch of the benchmark executable. The platform must not…modify the usual functioning of the platform based on the detection of the benchmark.”
Huawei Ascend P7 Performance in 3DMark Ice Storm Unlimited benchmark
- Play Store version score7462
- Renamed version score5816
As you can see, the Ascend P7’s score when running the public version of 3DMark is 28 percent higher than the score from a renamed, but otherwise identical version of 3DMark not available to the public or manufacturers. We also confirmed these results in our own test lab.
This clearly shows that the Ascend P7 is detecting 3DMark by name, and not by workload. If the “CPU configuration is adjusted dynamically according to the workload in different scenarios,” as claimed by Huawei in their response to Anandtech, then the score from the renamed version of 3DMark would be identical to the public version.
When a device detects 3DMark, and modifies its behaviour as a result, the score no longer reflects its real-world performance and cannot be used to make a fair comparison with other devices.
As Joshua says, “It’s not really acceptable that Huawei is doing this, and I’m disappointed that they have chosen this path.”
We share that disappointment and hope that this delisting will help persuade Huawei to realize the benefits of being fair and honest with their customers and the press.
