Intel BX80637I53450 Core i5-3450 Quad-Core CPU

The Intel Core i5-3450 is a third-generation (Ivy Bridge) quad-core processor on Intel's 22nm node, operating at 3.1 GHz base and 3.5 GHz single-core Turbo Boost with a 77W TDP. Its 6MB shared L3 cache is the Ivy Bridge i5 standard — large enough to hold frequently accessed working data for multi-threaded productivity workloads without repeatedly incurring DRAM latency. For its original platform generation, the i5-3450 represented a capable mid-tier desktop CPU; evaluated today, it occupies the budget refresh and legacy upgrade tier, offering a cost-effective performance step-up on LGA 1155 boards that previously housed i3 or Pentium G series CPUs.

This CPU's primary use cases in the current market are: upgrading an existing LGA 1155 system that cannot be replaced outright due to budget or infrastructure constraints; building an entry-level NAS or home server where multi-threaded throughput exceeds single-core frequency as the bottleneck; or equipping a basic desktop workstation for document editing, web browsing, and media playback. It is not a competitive choice for new builds — current budget platforms offer dramatically superior IPC, core counts, and memory bandwidth. For buyers who already own LGA 1155 motherboards, however, the i5-3450 delivers a tangible performance upgrade over dual-core and lower-clocked predecessors at minimal cost.
