The poster said it was suspicious on Anandtech's part.
Regardless, it was the final hardware and the final software was released to the phones before the review went up.
Any benchmarks that are improved over Anandtech's?
Ive seen other benchmarks for devices with the same SOC with totally different results. Don't believe me ,look them up and see for yourself. For example other benchmarks gave the same SOC a score of 1200(using default Chrome browser) for the sunspider test - big difference to 1800. All the other tests were way higher for graphics etc .
As others have said, it usually takes a while to tune the benchmarking softare to new SOC's - particularly Quad core ones. There's a number of factors they need to get right. Expect to see a whole different set of benchmarks for the SOC in 2 months time. Also, the sunspider test is run on stock browsers , the default browser under Android isn't the snappiest, so that result isn't a true indication of the HW capabilities - other snappier browsers could have been used - it's a bit of a silly test really - ie it doesn't reflect the so much the HW as it does the software (ie browser).
Example, here are some benchmarks for the Nexus 10 sunspider test
N10 using Chrome (default stock browesr) 1365ms
N10 using the QQ Browser 881ms
Reference - Iphone 5 (safari) 905ms
Quite the big difference isn't it!
Anandtech seem to race out with the benchmarks before they have gotten the benchmark software sorted for the SOC they are testing. It looks like they just want to be first to publish
To say the behemouth Snapdragon Pro S4 has mediocre-poor performance is ridiculous.
