AMD Radeon HD 7770M: specs and benchmarks

AMD Radeon HD 7770M

Summary

AMD started Radeon HD 7770M sales 24 April 2012. This is GCN 1.0 architecture notebook card based on 28 nm manufacturing process and primarily aimed at gamers. 1 GB of GDDR5 memory clocked at 4 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 64 GB/s.

Compatibility-wise, this is card attached via PCIe 2.0 x16 interface. Power consumption is at 32 Watt.

It provides poor gaming and benchmark performance at 6.01 percent of a leader's which is NVIDIA GeForce RTX 3080.
