But (not existing) SIMD capabilities, weak FPU etc. are a problem. Keep in mind that Intels Core and to some degree Core 2 architecture basically was an (very) improved P6 architecture chip. Thats hypothetic though because it seems that Nintendo went for a really cheap design. The MCM is what makes the CPU+GPU part expensive. A PPC750 based CPU with the right enhancements might have done very well. |
Marcan said Espresso's SIMD was weak, not non-existent.
"The Espresso is an out of order design with a much shorter pipeline. It should win big on IPC on most code, but it has weak SIMD"
