Sandra Multimedia benchmark gives both four-core processors nearly equal leads over the dual core E6750; the QX9770's slight advantage over the QX6850 is a reflection of its clock speed differential.
Sandra Memory Bandwidth credits the overclocked Core 2 Duo E6750 with its higher stable front-side bus, while using the same memory ratio as both four-core competitors. Similarly, the Core 2 Extreme QX9770's higher stock and overclocked FSB put it ahead of the QX6850.
