AMD Radeon HD 8770M technical specs and benchmarks

AMD Radeon HD 8770M

Summary

AMD started Radeon HD 8770M sales 1 April 2013. This is a GCN 1.0 architecture notebook card based on 28 nm manufacturing process and primarily aimed at gamers. 2 GB of GDDR5 memory clocked at 4.5 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 72 GB/s.

Compatibility-wise, this is card attached via PCIe 3.0 x8 interface.

It provides poor gaming and benchmark performance at 5.14 percent of a leader's which is AMD Radeon R9 390 X2.
