When AMD launched their Radeon HD6xxx series, we did a review of the Sapphire HD6850. Soon after, we found out that the review sample sent to us contained 1120 shader units instead of the 960 shader units that AMD prescribed for the HD6850. We quickly contacted Sapphire, and confirmed that the review sample did indeed contain 1120 shaders. We did what any reputable product analyst would do, and shipped our review sample back to Sapphire for a retail version of the HD6850 so we could rerun our benchmarks and obtain an accurate result.
