Cray C90

The Cray C90 series (initially named the Y-MP C90) was a vector processor supercomputer launched by Cray Research in 1991.

Compared to the Y-MP, the C90 processor had a dual vector pipeline and a faster 4.1 ns clock cycle (244 MHz), which together gave three times the performance of the Y-MP processor.

The maximum number of processors in a system was also doubled from eight to 16.

Maximum SRAM memory was between 1 and 8 GB, depending on model.

The D92, D92A, D94 and D98 (also known as the C92D, C92AD, C94D and C98D respectively) variants were equipped with slower, but higher-density DRAM memory, allowing increased maximum memory sizes of up to 16 GB, depending on the model.
