The integrated “system-on-a-chip” design
of the EV7 Alpha chip translates into the desirable
property of scaling all elements of system performance – processing,
memory access, and I/O access – linearly
with clock speed.
Performance gain 14% for AlphaServer
GS1280 with EV7z (EV7 at 1.3 GHz)
The property of linear scaling with clock speed
yields benchmark results for GS1280 AlphaServers
system with the new EV7z (EV7 running at 1.3 GHz)
systems that show a very consistent 14% increase
(+/- a few percent) over 1.15 GHz systems; 13%
attributable to clock rate increase and ~1% due
to improvements in Tru64 UNIX since the last benchmarks
were performed in Jan 2003.

Performance gain 16% for AlphaServer
ES47 & ES80
with EV7 at 1.15 GHz
Now available for the ES47 and ES80 systems, the
EV7 at 1.15 GHz also delivers a consistent improvement
in performance across the board when compared to
the systems with the EV7 running at 1.0 GHz. The
16% measured gain in performance comes from, again,
the 15% increase in clock rate and about 1% due
to improvements in the Tru64 UNIX.
The performance of the ES47 and ES80 systems with
EV7 at 1.15 GHz comes out virtually identical to
the performance of the GS1280 with 1.15 GHz EV7,
for the same configuration. This demonstrates again
the consistent, unified design across the entire
EV7 family AlphaServers – ES47, ES80 and
GS1280.

Price/performance improves 25%
The increase in performance for the new CPU speeds
at the same price as previous speeds coupled with
reductions in the prices for the current CPUs and
memory yield a price/performance reduction of about
25% across the board for all AlphaServer ES47,
ES80 and GS1280 models.
