e325 vs. x335, x382 and p615
Each system offers advantages over the others, depending on the environment.
The Bottom Line
1. Choose e325 (Opteron) for high 64-bit Linux/Windows price/performance. Choose x382
(Itanium 2) for the highest 64-bit floating point Windows performance. Choose p615 (IBM
POWER4+) for the highest 64-bit floating point performance on Linux/UNIX
®
(IBM AIX 5L).
2. Choose e325 for the best 32-bit price/performance. Choose x335 (Xeon) for the lowest-cost
32-bit solution.
3. Choose e325 for the lowest-cost 64-bit solution. Choose p615 for the most scalable 64-bit
solution.
4. Choose e325 or x335 for the greatest rack density (1U). Choose p615 for the most On
Demand features.
5. Choose x382 for the most high-availability features for Windows. Choose p615 for the most
RAS features overall.
6. Choose x382 for the most total memory (16GB) for Windows. Choose p615 for the most
PCI-X slots (6) for Linux/UNIX.
7. Choose e325 for the most cost-effective 32-bit to 64-bit migration path. Choose x335 or x382
for an Intel-only shop. Choose p615 for system partitioning.
8. Choose p615 for the most stable 64-bit OS and the most 64-bit applications. Choose x382 for
the most 64-bit Windows applications.
9. Choose e325 or x335 for an IBM ^ Cluster 1350 implementation. Choose p615 for a
Cluster 1600 environment.

HP Integrity rx2600
e325: The e325 with the Opteron processor can support a peak HyperTransport Tunnel
bandwidth of 16.0GB per second, up to 250% better than that of the Itanium 2.
Integrity rx2600: The peak front side bus (FSB) bandwidth of the Itanium 2 is 6.4GBps in a
system with a 400MHz FSB.
e325: Full processor clock rate memory access, due to the memory controller integrated into the
Opteron processor.
