ATI started Radeon HD 4850 X2 sales 7 November 2008 at a recommended price of $420. This is a TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at office use. 512 MB of GDDR3 memory clocked at 1.99 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 63.68 GB/s.
Compatibility-wise, this is dual-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 267 mm. One 6-pin and one 8-pin connectors are required, and power consumption is at 250 Watt.
It provides poor gaming and benchmark performance at
of a leader's which is NVIDIA GeForce RTX 4090.
