How well does the Sapphire R9 290X Vapor-X OC 4GB graphics card overclock? We were wondering the same thing and fired up the Sapphire TRIXX v4.8.2 overclocking utility to find out!
We left the VDDC offset at 25 and increased the GPU clock, memory clock and power limits to improve performance.
The Sapphire Vapor-X R9 290X out of the box with the latest Catalyst 14.4 drivers scored 10,318 points in 3DMark Fire Strike.
After our overclock we were able to get a score of 10,879 3DMarks. This is 5.4% performance improvement and shows that despite the fact this card is factory overclocked that there is still some more headroom available for end user overclocking. If you wanted to increase the voltages (VDDC Offset) there is likely more performance to be had, but we didn’t want to damage the loaner test card.
