Up to 2x faster.
Eight-core
processing power was once only top-of-the-line. Now it comes standard.
This time around, performance is more phenomenal than ever — up to two
times faster than the previous standard-configuration Mac Pro.1 And with the multicore technology enhancements of Mac OS X Leopard, the new Mac Pro is a force to be reckoned with.
More power with less power.
Inside
the new Mac Pro is the latest technology from Intel: Quad-Core Intel
Xeon “Harpertown” processors. These processors run at blazingly fast
speeds up to 3.2GHz. Based on the new 45-nm Intel Core
microarchitecture, they deliver amazing performance but still maintain
outstanding energy efficiency.
Cache count.
A
huge amount of L2 cache — 12MB per processor — keeps frequently used
data and instructions close to the processor cores and improves overall
performance. 6MB of cache is shared between pairs of processor cores,
allowing an individual core to use all the available shared cache at
any one time.
Built at full tilt.
With
the fastest Xeon architecture available, the new Mac Pro features
1600MHz dual independent frontside buses. These 64-bit buses give each
processor a direct connection to the system controller and deliver
improved processor bandwidth of up to 25.6GB per second — 20 percent
greater than the previous Mac Pro. With a new system architecture,
speedier system buses, and fast 800MHz DDR2 fully buffered DIMM memory,
Mac Pro memory throughput is up to 1.6 times faster than before.2
Every
Intel Xeon processor features an enhanced SSE4 SIMD engine. Capable of
completing 128-bit vector computations in a single cycle, SSE4 is ideal
for transforming large sets of data, such as applying a filter to an
image or rendering a video effect.
Smarter memory.
The
Mac Pro incorporates a 256-bit-wide, fully buffered memory architecture
with Error Correction Code (ECC), which corrects single-bit errors and
detects multiple-bit errors automatically. These features are
especially important in mission-critical or compute-intensive
environments. Apple designed a more stringent thermal specification for
the Mac Pro FB-DIMMs, so the internal fans spin at slower speeds and
keep the system quiet.
