ATI Mobility Radeon HD 3850: specs and benchmarks

ATI Mobility Radeon HD 3850


ATI started Mobility Radeon HD 3850 sales 4 June 2008. This is TeraScale 2 architecture notebook card based on 55 nm manufacturing process and primarily aimed at gamers. 0.5 GB of GDDR3 memory clocked at 1.5 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 48.0 GB/s.

Compatibility-wise, this is card attached via PCIe 2.0 x16 interface. Power consumption is at 35 Watt.

It provides poor gaming and benchmark performance at 6.62 percent of a leader's which is AMD Radeon R9 390 X2.
