Yes and no. If you compare memory capacity and GFLOPS, you will often find that those computers seem relatively unimpressive compared to what we have now. The value (and cost) in that hardware is often in capabilities and features that aren't necessarily reflected in numbers and bullet points.
If you were to take that machine and put it up against a 1 GFLOP desktop with the equivalent amount of RAM and disk storage, the Cray would annihilate it on the tasks that it was purchased for.

- sblank 17y agoGPUs (i.e. Nvidia and AMD/ATI) are the linear descendants of these supercomputers. Today's standard GPU's have vector processing units with fixed pipelines optimized for graphics operations. Glen Miranker and Jon Rubenstein of Ardent made their way to Apple where they spec'd/designed the Velocity Engine that went into the PowerPC G4/5. It had a 128-bit vector execution unit that required the use of the AltiVec API.
