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.
