Sad really can`t agree with him. My G-3/600MHZ Pegasos2 running Mplayer on MorphOS, plays Divx video, that my Athlon 1GHZ WinXP locks up and can`t handle.
Just don't run DIVX-HD on G3 processor.
Cheaper is not always better. Apple makes the switch to jump on the money train. Eating their own words that the PPC is better. Sony doesn`t seem to want to switch. They seem to produce tons of PPC machines that sell less than $150. One word "CELL"
Pitiful VMX performance (e.g. Alias cloth simulation). Hence SJ’s statement on Cell being less effective than G5.

Porting to the Cell Architecture
The most notable features of the Cell processor architecture are the IBM® Power-based RISC
CPU core (PPE), the 8 SIMD vector units (SPEs) and the impressive bandwidth that can be
leveraged to obtain maximum performance from the architecture.
In order to port the prototype cloth simulator to the Cell processor, the code and data structures
had to be restructured. First, changes had to be made to allow for parallelization of the algorithm(1).
Even for more conventional multi-core targets, this is a challenging process. With the Cell
architecture, there is the additional requirement to manage memory transfers between the main
processor (the PPE) and the SPEs. Second, where feasible, scalar code was re-written to take
advantage of the vector support in both the PPE and the SIMD units.
It seems that Pentium IV’s code was not optimized, since the original code needed to be restructured for vectorization and parallelization i.e.
such optimizations also benefit Pentium IV side (1) i.e. for SSE2/SSE3 and SMT.
In Alias|Wavefront Maya 6.0 Zoo Render benchmarks, Opteron @2Ghz easily beats Intel Nocona Xeon @3.4 GHz. In most cases, Yonah is clock to clock similar to Athlon 64 X2.
