We previously had looked at the ATI Radeon HD 4550 and Radeon HD 4670, but if you are looking for a graphics card that's positioned between the two and costs less, there is the Radeon HD 4650. The Radeon HD 4650 is clocked the same as the Radeon HD 4550, but is based upon the RV730PRO GPU and is able to provide a bit more processing power than the lesser RV710 solution. Sapphire though manufactures a Radeon HD 4650 graphics card that operates well beyond the reference core and memory frequencies for the RV730PRO and sells it at a very affordable price. In this article we are seeing how well the Sapphire Radeon HD 4650 512MB OC graphics card can perform under Linux.


- 650MHz Core Clock / 900MHz Memory Clock
- Dual DVI Connectors
- PCI Express 2.0 Interface
- 512MB 128-bit GDDR3
- Native HDMI Support
- 7.1 Audio Channel Support
- 320 Stream Processing Units
- Unified Video Decoder 2 / Avivo HD


The Sapphire Radeon HD 4650 OC arrived in packaging to the previously reviewed Sapphire Radeon HD 4550 and HD 4670. The 512MB of GDDR3 memory is advertised along with this card being an overclocked model, HD video support, PCI Express 2.0 capabilities, HDMI, and other features. Included with the graphics card was a Sapphire driver CD (for Windows XP and Vista only), video output adapter, one composite video adapter, one DVI to VGA adapter, one DVI to HDMI adapter, and lastly there was the quick installation guide. This is essentially the same set of items you will find with inexpensive graphics cards from Sapphire and other AIBs.
