- 32-core Dual Intel Xeon E5 2630 V3 (Passmark: 12797x2=25594)
- 48GB RAM
- 1x 128GB SSD
- 16-core AMD Opteron 6272 (Passmark: 6748 to 10245... benchmarks vary widely)
- 64GB RAM
- 2x 256GB SDD
While the new server has drastically less processing power (20-40% of the two Xeon's), it has more RAM and two SSD's, which is particularly useful for a database server (our entire database can fit in RAM and the OS can be on one SSD, and the database data can be on another SSD, which will reduce resource contention).
Now, why do I think it's OK to significantly downgrade the CPU? Check out the graph - the CPU is over 95% idle at all times (the yellow area of the graph is the CPU not doing anything). So basically we're paying for a super computer CPU when we don't need it at all.
Fingers crossed this gamble pays off.
