Oracle have announced new systems based on the new T5 and M5 processors. The T5 has doubled the number of S3 cores from the T4 and increased the clock frequency to 3.6GHz.
The M5 processor is also based on the S3 core (rebranded M4) clocked at 3.6Ghz but is has 6 cores and 48MB L3$. The M systems supports up to 32 M5 processor so a fully configured systems will have 192 cores and 1536 strands (hardware threads). The M5-32 have 32TB of memory in a single system.
Old and existing processors for reference:
T3 16 cores @ 1.65GHz 6Mb L2$ 1-4 socket systems PCIe 2.0
T4 8 cores @ 3.0GHz 4MBL3$ 1-4 socket systems PCIe 2.0
T5 16 cores @ 3.6GHz 8MB L3$1-8 socket systems PCIe 3.0
M5 6 cores @ 3.6Ghz 48MB L3$ 32 socket system PCIe 3.0
Oracle claims 2.3x performance gain compared to the T4 with increased single-thread performance.
All new systems both T5 and M5 supports LDOM (Oracle VM for SPARC).
Did everyone read that the M5-32 Supports 32TB of memory? No wounder they had to rewrite the virtual memory subsystem in Solaris 11.1
