Earlier this month the ATI Radeon HD 4600 series from AMD was unveiled as the new mid-range graphics cards derived from their flagship RV770 graphics core. The Radeon HD 4650 and Radeon HD 4670 are the two RV730-based products now available. The ATI Radeon HD 4670 may not be able to compete with the Radeon HD 4800 series in all of the tests, but at a price of under $100 USD is it worth pursuing? For this article we have our hands on the brand new Sapphire Radeon HD 4670 512MB graphics card as we test it on Ubuntu Linux to see how well it can perform in our OpenGL tests and overclock with the recently added OverDrive support.

The Sapphire Radeon HD 4670 512MB graphics card had arrived in similar packaging to other Sapphire graphics cards we have reviewed in the past. Advertised on the exterior of the packaging was the 7.1 channel audio, 3840 x 2400 maximum resolution, 512MB of GDDR3 memory, HDMI support, PCI Express 2.0, HD video, and the energy efficiency of this graphics card. Included with this PCI Express graphics card was an S-Video to RCA video adapter, one CrossFire bridge, component video adapter, DVI to HDMI adapter, DVI to VGA adapter, Sapphire driver CD, graphics card user's manual, CyberLink DVD Suite, Ruby ROM Volume II, and CyberLink PowerDVD 7. Sadly, on the Sapphire driver CD is still just the Windows XP/Vista drivers. Sapphire Technology has yet to include any Linux driver on their product CDs.
