Image and Video Editing
If the dual-core AMD Athlon 64 X2 4800+ has always been a leader in Photoshop, now the situation has changed. Pentium Extreme Edition 955 wins the title of the fastest CPU here. Even when running at its nominal speed, it outperforms AMD Athlon 64 X2 4800+ by about 5%.
The same is true for the performance in Adobe Premiere.
3D Modeling and Rendering
Although the final rendering in 3ds max can be easily split into a few parallel threads, we cannot say the same about the work in viewports. So, we see two completely different results in one and the same application. Dual-core processors are leading the race during final rendering, while in viewports the results is just the opposite. However, the overclocked Pentium Extreme Edition 955 working at 4.26GHz wins in both cases anyway due to its higher working frequency.
