As you can see, the current UltraSPARC III is targetted to scale from 750 MHz to 1200 MHz, meaning that at it's current 1050 MHz, it is almost at the end of its planned frequency ramp. Picking up where it leaves off is the UltraSPARC IV, which is expected to scale up to 2 GHz. It has been strongly rumored in the past that Sun's follow-on to UltraSPARC III will be an on-chip multiprocessing solution leveraging the UltraSPARC III core. This chip will most likely appear on TI's 0.13µ process, and it has been stated that the processor will be introduced sometime late this year at a top initial speed of 1.5 GHz. Lastly, while very little public information exists on UltraSPARC V at this point in time, it has been indicated by various Sun representatives that the processor will be a new core (i.e. not using USIII) focusing on improving both ILP and TLP. UltraSPARC V is said to launch late next year at up to 2.1 GHz, though it is hard to say whether or not it will make that target from what information has been released about it thus far.
Plus some of this...
According to the roadmap, the e-Series line of processors will also receive a boost sometime in the near future. The UltraSPARC IIe, an 0.18µ UltraSPARC II with integrated northbridge (memory interface, PCI interface, etc.) and 256 KB on-chip L2 cache, is currently shipping at 500 MHz in the Netra X1 and Blade 100 systems, but is expected to scale as high as 700 MHz. Furthermore, it appears that a follow-on chip not labeled in the roadmap will scale from 700 MHz to 1.1 GHz or above before a next-generation core is expected to take over and scale to 2 GHz in the rather distant future.
And a little on Linux, Cobalt, and AMD...
Sun has also made headlines recently for it's recent announcement of support for Linux at the low-end of the market through a new line of single and multi-processor servers based around the x86 architecture. There has been speculation that this new line of low-end servers will be based on AMD's upcoming 64-bit Hammer processors, but there is currently no official information regarding the specific microprocessors to be used in these systems. At the same time, the company plans to expand the Cobalt line of server appliances, which run Linux and use Intel Pentium III and AMD K6 processors. Sun has also inked a deal with Lineo to port its embedded Linux operating system to the UltraSPARC IIe platform.
