Although the last Adobe Photoshop version is optimized for SMP systems, these optimizations touch upon not all functions and filters. Therefore, although Intel V8 has an advantage here, it doesn’t get too far away from the other testing participants.

Although Adobe Premiere Pro supports multi-processor configurations, the eight-core system doesn’t perform impressive enough. It yields a little bit to the single-processor quad-core system with Core 2 Extreme QX6800. If we take a closer look at this test, we will see that the CPU utilization in Intel V8 during video rendering doesn’t exceed 50%. It is clear indication that the computational potential of the processor is not the bottleneck here. The performance may be limited either by the memory subsystem, or by the processor bus bandwidth, because these busses not only transfer data to the memory but also deal with ensuring coherency of four L2 caches.
