Something didn't look right about several of the percentages vs. the displayed scores. AnTuTu was displayed as 22% faster but the math based upon the scores says 19%. Also the Geekbench 5 numbers for multi core performance show 22% but the math based upon the scores shows 19%, which matches the single threaded performance. 3% may not seem like much of an error in the numbers but in the context of the results between 22% and 19%, it's a 14% difference in the displayed result vs. the math.

Hi, Stephen Can you tell how do you get 19% when comparing 581,243 and 475,782?

The Adreno 650 has 1,024 ALU's while the Adreno 640 has 768 ALU's. The Adreno 630 has 512 while the Adreno 530 has 256 ALU's. Qualcomm started giving incremental updates to the there Adreno GPU's by upping the ALU count by 50%. We knew the Adreno 330 had 128 ALU's from the SD800 and also the SD808 but the Adreno 418 was running on a LPDDR3-933(1866) with 14.9GB/s memory bandwidth and the Adreno 420 in the SD805 had a CPU clock frequency of 2.7GHz and a 128-bit memory controller using LPDDR3-1600(3200) with 25.6GB/s memory bandwidth which helped the GPU gain even more performance. The Adreno 430 in the SD810 had 192 ALU's. But, it wasn't until the SD820/821 when they started to use 256 ALU's and add 50% (256 ALU's) in increments of 256. So now we know how many ALU's Qualcomm is using when they say 50% more ALU's. We can measure FP32 compute in Gflops and now Teraflops thanks to the SD855+ and SD865. Also, just by using basic calculations can measure them but, The question is. What will the SD875 bring to the table.
