AMD Radeon HD 7950 technical specs and benchmarks

AMD Radeon HD 7950

Summary

AMD started Radeon HD 7950 sales 31 January 2012 at a recommended price of 449 USD. This is a GCN 1.0 architecture desktop card based on 28 nm manufacturing process and primarily aimed at gamers. 3072 GB of GDDR5 memory clocked at 1.25 GHz are supplied, and together with 384 Bit memory interface this creates a bandwidth of 240 GB/s.

Compatibility-wise, this is 2-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 267 mm. An additional 2 6-pin power connectors are required, and power consumption is at 300 Watt.

It provides good gaming and benchmark performance at 28.67 percent of a leader's which is NVIDIA TITAN Xp.

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.
