Key Problem: Memory Density

Conventional GP Computation Wisdom:
- Linear: 1 Byte of memory per flop
May be somewhat reduced at high end
- Large scale simulations: Storage = Flops^3/4
- Recent petaflops studies: Some large computations at 0.01 B/Flop
Graphics & other embedded applications
- Current << 1 B/op
- BUT!: Future requires more
  - Increased resolution/color
  - 3D rendering
  - Full motion video compression/decompression
- Conclusion: DRAM Essential!
