The different amount of RAM is the last think to notice here. The OMAP L138 on the hawkboard is an ARM9 (+ C674xDSP) at 375/456MHz, the OMAP4 of the pandaboard

The different amount of RAM is the last think to notice here. The OMAP L138 on the hawkboard is an ARM9 (+ C674xDSP) at 375/456MHz, the OMAP4 of the pandaboard is a dual core Cortex-A9 at 1GHz.
They are completely in two different class. I too hope for the price.
- pmjordan 16y agoThe different amount of RAM is the last think to notice here. That depends mainly on the use you have in mind. For my purposes, the Hawkboard's CPU would probably be fine. But yeah, the Pandaboard is quite a beast - twice the computing power of an iPad, if I'm not mistaken. (not counting the DSP)
- codedivine 16y agoMore than twice I would say. iPad's A4 is a tweaked Cortex A8. Cortex A9 is out-of-order compared to in-order A8 and will likely be faster per clock.
- mansr 16y agoThe A9 is readily 25% faster per clock than the A8 for scalar integer operations. Scalar floating-point is 5-10x faster depending on the exact operations. Vector instructions are mostly the same or slower than A8 due to lack of the limited dual-issue present in A8. I have yet to run a proper benchmark to compare the difference in vector performance in realistic situations.
