AMD Radeon HD 8790M technical specs and benchmarks

AMD Radeon HD 8790M

Summary

AMD started Radeon HD 8790M 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 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 MXM-A (3.0) interface.

It provides poor gaming and benchmark performance at 6.56 percent of a leader's which is AMD Radeon R9 390 X2.

Compatibility, dimensions and requirements

Information on video card compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus - if the video card is inserted into the slot instead of being soldered to the notebook motherboard.
