AMD Phenom II X4 945
Benchmarks & Specs

Last updated:
The AMD Phenom II X4 945 represented a significant step in its era. With its four processing cores, it offered remarkable performance for the time. It enabled users to run multiple applications smoothly simultaneously. The basis of this processor was the robust Deneb architecture. This was largely responsible for its stability and reliability.

It was manufactured using the then-modern 45 nm process. This contributed not only to efficiency but also to good heat dissipation. Another highlight was the generous 6 MB Level 3 cache. This ensured faster data access. We remember how well it performed in many systems. Whether for office work or multimedia, the AMD Phenom II X4 945 delivered reliably.

It showed that AMD was on the right track at the time. Its maximum memory bandwidth of 21 GB/s supported the overall system performance. A solid all-rounder for its time, which has its place in computer history.
