Intel Core i7 9700 8-core LGA1151

The Intel Core i7-9700 is a 9th Gen 8-core desktop CPU that still holds up well for gaming thanks to its 4.7GHz boost and strong single-thread performance. It's a great drop-in upgrade for 300-series motherboard owners, especially at the lower end of the used price range. Skip it if you're building new, and budget for an aftermarket cooler because the stock one is rough.

Let's talk numbers. The i7-9700 puts up a PassMark multi-thread score of 13168 and a single-thread score of 2742. In our database, that single-thread number lands in the 77th percentile for desktop CPUs, which translates to strong performance in games and snappy everyday use. The multi-thread score sits at the 65th percentile, so it's above average but not a chart-topper. That's the hyperthreading tax showing up. Eight physical cores without SMT means you get eight threads, period. For gaming, that's fine. For rendering or streaming while gaming, you'll feel the ceiling.

The 4.7GHz boost clock is the real star here. Coffee Lake chips clock high, and the i7-9700 holds its boost well under a decent cooler. With the stock cooler, expect thermal throttling under sustained all-core loads. With a USD 30-40 tower cooler, it stays cool and quiet. The 65W TDP is also nice for a chip this capable, meaning it won't turn your case into a space heater. Memory support is DDR4 up to 128GB across two channels, and PCIe 3.0 is fine for any GPU short of the absolute newest flagships, where you might leave a few percent on the table.

The elephant in the room is AMD. The Ryzen 7 7800X3D absolutely destroys the i7-9700 in gaming, but it's also a completely different price class and requires a new motherboard and DDR5. That's not really a fair fight. A more realistic comparison is something like a used Ryzen 5 3600 or Ryzen 7 3700X, which often sell for similar money on the used market. The 3700X has 8 cores and 16 threads, so it wins multi-threaded workloads, but the i7-9700's higher clocks give it an edge in older games that favor single-thread speed.

Against other Intel options, the i7-9700K is the obvious sibling. Same chip, unlocked multiplier, and usually only slightly more expensive used. If your board supports overclocking, the K version is the better buy. The i5-9600K is cheaper but gives up two cores. And if you're looking at Xeon options like the E5-2637 V2, that's a server chip with very different priorities, lower clocks, and a different socket entirely. Not a real alternative for a desktop gamer.

Value is where things get tricky. Used listings in the US range from USD 100 to USD 555, which is a massive spread. At the low end, around USD 100-150, this chip is a fantastic budget upgrade for anyone on a 300-series board. At the high end, you're paying more than a new Ryzen 5 7600 or even a used Ryzen 7 5800X3D, and that makes no sense. The best deals we're seeing are the used and refurbished listings on Newegg, where prices sit at the lower end of that range. In Canada, the spread is CAD 228 to CAD 445, and again, the cheaper listings are the only ones worth considering. If you're paying more than about USD 150 for an i7-9700 in 2025, you should probably be looking at a platform upgrade instead.

The Intel Core i7-9700 is a 9th Gen Coffee Lake desktop CPU that still pops up on the used market for anywhere from USD 100 to USD 555, depending on condition and seller. It's an 8-core, 8-thread chip with a 3.0GHz base clock, 4.7GHz boost, 12MB of L3 cache, and a 65W TDP. No hyperthreading here, which was a weird choice from Intel at the time, but the raw clock speed helps make up for it in games and everyday tasks. It drops into any LGA1151 300-series motherboard, so if you're running a Z370 or Z390 board with an older i3 or i5, this is a drop-in upgrade path.

People searching for this chip are usually asking two things: is the i7-9700 still good for gaming in 2025, and is it worth buying used? The short answer to the first is yes, mostly. The single-thread score of 2742 in PassMark puts it well above average for its class, and that's what matters for most games. The multi-thread score of 13168 is solid but not spectacular, which is what you'd expect from a chip without hyperthreading. For productivity work like video editing or heavy multitasking, it'll get the job done but won't blow anyone away.

One thing to know before you buy: the stock cooler Intel shipped with this thing is not great. Multiple owners report it's loud and struggles under sustained load. If you're buying the CPU by itself, budget for a decent aftermarket cooler. The integrated UHD Graphics 630 is also pretty weak, but if you're buying an i7-9700, you almost certainly have a dedicated GPU anyway.

Skip the i7-9700 if you're building a new PC from scratch. The LGA1151 platform is dead, DDR4 is aging, and you'll get better long-term value from a modern Ryzen 5 or Core i5 build. Also skip it if you do heavy multi-threaded work like video rendering or 3D modeling, the lack of hyperthreading will hold you back compared to a Ryzen 7 3700X or newer chip at a similar price. And if you're not comfortable buying used or refurbished hardware, the new-in-box listings for this chip are often absurdly overpriced, so you'd be better off putting that money toward a current-gen CPU.

Should you buy an Intel Core i7-9700 in 2025? If you already have a 300-series motherboard and you can find one for around USD 100-150, yes. It's a meaningful upgrade from an i3 or i5 of the same generation, and it'll handle modern games at 1080p or 1440p with a decent GPU without breaking a sweat. The single-thread performance is still genuinely good, and that's what keeps this chip relevant.

But if you're building a new system from scratch, don't. The LGA1151 platform is a dead end, DDR4 is on its way out, and you can get better performance per dollar from a modern budget build. The i7-9700 is a great upgrade chip, not a great foundation. Buy it used, pair it with a proper cooler, and enjoy it for what it is: a fast, cool-running 8-core that punches above its weight in games.
