Intel Core 2 Quad Q9505 4-core LGA775

The Core 2 Quad Q9505 is a 2009-era quad-core that scores 22.5 out of 100 overall. It's cheap at around $50 USD and works fine for keeping ancient LGA775 systems alive. For anything modern, it's too slow, too power-hungry, and too dead-end to recommend.

The PassMark numbers tell the story. 2177 multi-thread and 1187 single-thread puts this chip in the 27th and 24th percentiles respectively. That's not just slow, it's 'your phone probably benches higher' territory. The 6MB of L2 cache helps a little with older games and basic multitasking, but the 95W TDP means you're burning real power for very little return. Efficiency lands in the 17th percentile, which is a polite way of saying this thing is a space heater that occasionally does math. For retro builds or basic office work it's fine. For anything modern, it's a slideshow.

Stacked against the AMD Ryzen 5 7600, this thing looks like it belongs in a museum. The Ryzen 5 absolutely obliterates it in every metric we track. Even the Dell Xeon E5-2637 V2, itself an old server chip, runs circles around the Q9505 in multi-threaded workloads. The PC Server and Parts E5-2697 v2-cr is another budget option that offers dramatically more cores and threads for not much more money, assuming you have a board that supports it. The be quiet! and Thermal Grizzly entries in our comparison list are cooling products, not CPUs, so they're not direct competitors, but they do highlight that modern builds need modern cooling, something this old Intel chip never really worried about.

At $50 USD it's hard to call this a rip-off. You're buying a working CPU for less than the cost of a decent dinner for two. The affordability score of 45.6 out of 100 reflects that it's cheap, but you're also buying into a platform with zero future. The 1 month warranty is a red flag though. If this chip dies on day 31, you're out fifty bucks and back to square one. For keeping an old machine alive, the math works. For anything else, save your money.

The Intel Core 2 Quad Q9505 is a fossil from 2009 that still shows up on Amazon because someone, somewhere, has an LGA775 board they refuse to let die. Four cores, 2.83GHz, 6MB of L2 cache. It was a solid mid-range chip back when Obama was in his first term. Today it's a budget stopgap for keeping ancient hardware alive, not a serious performance purchase.

We scored it 22.5 out of 100 overall. That sounds brutal, and it is. But context matters. If you're nursing along an old Dell or HP office box and just need a working CPU for $50, this does the job. Just don't expect it to compete with anything made in the last decade.

Skip this if you're building a new PC, period. Also skip it if you need any kind of modern performance, video editing, streaming, or gaming beyond retro titles. If your board supports a Xeon mod or a faster Core 2 Quad like the Q9650, spend the extra few bucks there instead. And if you're expecting any kind of warranty support, the 1 month coverage should scare you off.

Buy this if you have an LGA775 motherboard with a dead or dying CPU and you just need the machine to boot again. It's a cheap, reliable drop-in replacement for old office PCs, basic web browsing, and retro gaming rigs. Anyone building a new system should pretend this product doesn't exist. It's not a value play, it's a life support purchase.
