G725 FMA and CVT units

Venkatesh K R

Hello Forum,

In some of open-source pages have seen that earlier version of G725 has 2 FMA units and now G725 supports 2 CVT units ("Doubled shift-convert unit throughput" in Mali-G725 | 5th Gen Architecture for Premium Mobile GPU​ – Arm®). But Arm GPU data sheet shows FP32 operations/cycle, FP16 operations/cycle is same in G715, G720 and G725. So, I am confused how to interpret the 2 FMA units as throughput is same.

My basic understanding is each shader core has 4 Arithmetic units or Processing Units (PU) since G710 and each PU has 1 FMA, 1 CVT, 1 SFU pipelines. Now G725 supports 2 CVT's, does that mean it has 1 FMA, 2 CVT, 1 SFU pipelines for each PU?

Thanks

Venkatesh
