This allows great flexibility of upgrading by preserving the original investment of CPU modules. Sun Blade 1000 is targeted at the high-end workstation market. Sun Blade 1000 is the direct successor of the Ultra 60. For certain situations where individual CPU performance and large RAM capacity are more important than total CPU count, an Ultra 80 can be replaced by a Sun Blade 1000. Multiple CPUs allows customers to upgrade as needed without incurring undue costs upfront.
Some competitors force two CPUs without the option of starting off with only one.
A customer with an existing Ultra workstation may transfer the selected graphics card to a Sun Blade 1000 system. This allows customers to reap even better return on investment by continued use of their current graphics investment. The supported graphics in Sun Blade 1000 are PGX32, Creator3D, Elite3D m6, and Expert3D. Elite3D m3 is not supported in Sun Blade 1000. Sun Blade 1000 has 8 GB RAM capacity that allows more of an application to run directly in RAM at far faster speeds than disk. This gives the customer application maximum speed for faster completion or for saving time for conducting more computations.
