In case you missed it, earlier this month many questioned the AnTuTu benchmark results for Intel's Atom Z2580 processor, which showed it ranking above offerings from Samsung, Qualcomm, and NVIDIA. Such complaints led to a revelation by consulting firm BDTI that the instructions were not being completely executed by the Intel processor, and as a result AnTuTu has released an updated version to correct the issue.
The issue resulted from the ICC compiler that was used with the Intel processor, which reportedly has been around since approximately version 2.9.4. Other processors didn't suffer the same issues because the tool utilized a GCC compiler instead. The specific cause of the issue was by incomplete RAM testing, which caused the incorrect results.
The ICC compiler is still used for Intel processors in the new version that has been released, but the results are drastically different, and as a result the Atom Z2580 has seen a 20-percent drop in its ratings. In particular, the RAM score - where the issue was located - dropped by 50-percent.
The Qualcomm Snapdragon 600 processor and Samsung's offerings, meanwhile, saw their scores hold nearly steady after the change, and in particular the Exynos 5 Octa from Samsung now ranks above the Intel processor. Reportedly, AnTuTu will be releasing new testing standards in August, and possibly the next version of the software.
Once the new release is out, we'll be able to compare it to current numbers and see how the results change again. AnTuTu did not release what changes were made to the tool that caused the change in results, and so some continue to question the accuracy of the numbers despite them falling in line with similar results from other software.
