ATI Mobility Radeon HD 4670 technical specs and benchmarks

ATI Mobility Radeon HD 4670

Summary

ATI started Mobility Radeon HD 4670 sales 9 January 2009. This is a TeraScale 2 architecture notebook card based on 55 nm manufacturing process and primarily aimed at gamers. 0.5 GB of GDDR3 memory clocked at 1.6 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 25.6 GB/s.

Compatibility-wise, this is card attached via MXM-A (3.0) interface. Its power consumption is at 35 Watt.

It provides poor gaming and benchmark performance at 5.32 percent of a leader's which is NVIDIA Quadro P6000.

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.
