Galaxy Note 3 model# GT-N7200 was spotted on the AnTuTu Benchmark chart. From the model number, we suspect the device is likely to be the sequel of GT-N7100, which is the Samsung Galaxy Note 2.
The Samsung Galaxy Note III scored lower than the Galaxy S4 in AnTuTu, Galaxy Note typically have overclocked chipsets compared to their Galaxy S counterparts, so we expect the finished product to be clocked above 1.6GHz as far as processor is concerned.
So the Galaxy Note III will run Android 4.3 on a CPU clocked around 1.6GHz. That's coincidentally the same clockspeed as the Exynos 5 Octa found in the I9500 Galaxy S4 phone.
Keep in mind that the scores of the benchmark can be edited easily by any Android developer. Samsung is yet to confirm the news on this matter.
