Our take on the Intel Core 2 Quad Q9450 4-Core Processor

The Core 2 Quad Q9450 is a socket LGA775 desktop processor with four cores at 2.66 GHz, a 1333 MHz front-side bus and 12 MB of L2 cache. It was one of Intel's first mainstream 45nm quad-cores, and its large cache and four cores still handle office work, browsing and older games on a period build. Against the Q6600 it runs cooler and faster per clock; against the Q9550 it gives up some clock speed and cache. It suits people repairing or building an LGA775 system, not anyone buying new.

Pros
  • Four cores at 2.66 GHz
  • 12 MB L2 cache, generous for its generation
  • 45nm process runs cooler than the 65nm Q6600
  • 1333 MHz FSB matches many late LGA775 boards
  • Cheap way to add cores to an older machine
Cons
  • Old architecture with weak per-core speed by today's standards
  • Needs a board and BIOS that support 1333 MHz FSB and 45nm chips
  • No integrated graphics, so a discrete GPU is required
  • Runs hot under sustained load with the stock cooler
  • No modern instruction sets or platform features

What reviewers say

Owners of period builds rate the Q9450 as a solid, cool-running quad-core that was a clear step up from the Q6600. Most criticism is about its age: it is slow next to any modern CPU and depends on a compatible LGA775 board.

What people mention
  • PerformanceMixedOwners find it strong for its generation but slow by current standards.
  • HeatPraisedThe 45nm die runs cooler than the older 65nm quad-cores.
  • CompatibilityCriticisedIt needs an LGA775 board with BIOS support for 1333 MHz FSB and 45nm chips.
  • ValuePraisedBuyers see it as an inexpensive way to add four cores to an old desktop.
  • Cooler noiseCriticisedThe stock cooler becomes audible under sustained load.

Questions and answers

Is the Q9450 worth it over a Q6600?
Yes, if your board supports it. The Q9450 has a faster bus, more cache and a cooler 45nm design, so it is quicker and quieter than the Q6600.
Will it fit my motherboard?
It uses socket LGA775 and a 1333 MHz front-side bus. Check that your board lists support for 45nm Core 2 Quad chips and update the BIOS first.
Does it have integrated graphics?
No. You need a discrete graphics card or a board with onboard video.
How does it compare with the Q9550?
The Q9550 runs at a higher clock speed with the same 12 MB cache and socket, so it is faster. The Q9450 runs cooler and is easier on older boards.
What is in the box?
This is sold as a processor. A cooler is not guaranteed, so confirm before buying or plan on an LGA775 cooler.
Can I overclock it?
Some owners push it modestly on boards with good cooling, but gains are limited and depend on the chipset and BIOS.
Where is the Intel Core 2 Quad Q9450 4-Core Processor cheapest?
At Tech Network Supply LLC, for $78.12, as of our latest check.
