Well they are correct in a sense that they show us what code path Zambezi runs(AVX and not FMA). Also they kinda align with both opteron 6200 series sisoft results. 2P 6282SE gets 585 @ 2.5Ghz which equates (with perfect scaling of 4x) to 147 or 164mpix/s @ 2.8Ghz (11% higher than 8C Zambezi @ 2.8Ghz). 2P 6220 @ 3Ghz gets 315mpix/s ;with perfect scaling => 315/2=157.5mpix/s or @ 2.8Ghz 147mpix/s (exactly the same as that Zambezi @ 2.8Ghz). So we can say now that results of the Zambezi sample are true for SIMD and kinda off for integer test.
