While Sun Microsystems Inc has received a phenomenal amount of support for reinvigorating its Solaris operating system on x86 platforms and for embracing the hybrid 32-bit and 64-bit Opteron processors from Advanced Micro Devices as its core workstation and entry server offerings, the company has been unusually tight-lipped about its plans for the future Opteron machines, which its engineers are cooking up right now in the labs and hopefully to bring to market before 2005 ends.
They report about AMD looking at SI-28 in a joint-program, acknowledging "a proper balance between performance and cost" has not been found yet. (Coded as usual: Isonics expects the "..." will be found).
Interestingly, they dont list AMD in subsequent market predictions as an important user of SoI. So it appears AMD folded it after (or even without) trying. For good, I would not want too much ressources spent on looking out for a panacea. SI-28 is not. Neither is SoI, btw. ;)
