AMD FX-Series FD9590FHHKWOF 8-core Socket AM3+

The AMD FX-9590 is an 8-core AM3+ CPU with a 5.0GHz turbo clock and a 220W TDP. It's the fastest chip for that socket but gets beaten by modern budget CPUs in most tasks. Only worth buying if you already have a compatible motherboard and serious cooling.

In our database, the FX-9590 lands at 6,834 in PassMark multi-thread and 1,807 in single-thread. That puts it right around the middle of the pack for multi-threaded work and single-threaded tasks, which is not where you want an 8-core flagship to be. The single-thread score is the real problem here. A lot of everyday apps and older games lean hard on one or two cores, and this chip just doesn't have the per-core grunt to keep up with even budget modern CPUs.

Multi-threaded performance is more respectable. If you're doing video encoding or other workloads that can actually use all 8 cores, the FX-9590 can still chew through tasks. But the efficiency score in our database is rough, sitting at just 31.4 out of 100. That 220W TDP means you'll need serious cooling and a motherboard with beefy VRMs just to keep the thing stable. One reviewer mentioned hitting 5.1GHz with a solid cooling setup, but another couldn't hold 5GHz on all 8 cores even with a Corsair H100i. Your mileage will vary a lot depending on your board and cooler.

Compared to something like the Intel Core Ultra 9 285K, the FX-9590 is not even in the same conversation. The Ultra 9 runs circles around it in single-threaded performance, efficiency, and platform features. The FX-9590's 5GHz clock sounds impressive until you realize it's doing less work per clock than a modern chip running at half the speed. The G.Skill Trident Z Neo and be quiet! Ryzen 3 Dark Rock Pro 5 aren't direct CPU competitors, but they show up in our database as alternatives people consider when building around this era of hardware. If you're looking at those, you're probably better off going with a Ryzen platform anyway.

The ADVB3 Phenom II X6 is an interesting comparison because it's another older AMD chip. The FX-9590 beats it in raw clock speed and core count, but the Phenom II X6 has a reputation for being more stable and easier to cool. If you're on a tight budget and just need a working AM3+ system, the Phenom II X6 might actually be the smarter pick. The FX-9590 is the kind of chip you buy because you want the fastest thing that socket ever supported, not because it's the sensible choice.

Value is where the FX-9590 gets really tricky. At USD 222, it's not a terrible price for a collector or someone upgrading an old AM3+ system. But the European listings range from EUR 346 to EUR 437, and that's a lot of money for a chip that gets beaten by modern budget CPUs in most tasks. If you're shopping in Europe, the best deal we're seeing is at the lower end of that EUR range, but even then you have to factor in the cost of a high-end cooler and a motherboard that can actually handle 220W. For most people, that money would be better spent on a modern platform with a clear upgrade path.

The AMD FX-9590 is one of those CPUs that sounds like a monster on paper and then makes you deal with the consequences in real life. It's an 8-core, 8-thread Vishera chip from the FX series, running a 4.7GHz base clock with a 5.0GHz turbo. That's the kind of number that made people do a double take back in the day, and honestly, it still looks impressive on a spec sheet. But this thing pulls 220W and doesn't even come with a cooler, which tells you a lot about what AMD expected from buyers.

People searching for this chip are usually asking the same things: is the FX-9590 good for gaming, can it handle modern workloads, and is it worth buying in 2025? The short answer is that it's a niche pick for people who already have an AM3+ motherboard and want the fastest chip that socket ever saw. For everyone else, there are much better ways to spend your money.

Pricing is all over the place depending on where you look. We're seeing it around USD 222 in the US, EUR 346 to EUR 437 across European listings, and CAD 510 in Canada. That spread alone should make you pause before clicking buy.

Skip the FX-9590 if you're building a new PC or upgrading from anything made in the last several years. The single-thread performance will bottleneck modern games and everyday apps, and the 220W power draw means you'll spend extra on cooling and electricity. If you need a budget CPU for gaming or productivity, look at a modern Ryzen 3 or Intel Core i3 instead. You'll get better performance, lower power consumption, and an actual upgrade path. This chip is only for AM3+ owners who know exactly what they're getting into.

Should you buy the AMD FX-9590? If you already have an AM3+ motherboard with strong VRMs, a high-end cooler, and you want to max out that platform, then sure, it's the top dog for that socket. You'll get 8 cores at 5GHz and it'll handle older games and multithreaded workloads fine. But if you're building a new system or upgrading from anything modern, this chip makes no sense. The single-thread performance is a bottleneck, the power draw is absurd, and the price is often higher than a modern budget CPU that beats it in every way.

For most people, the answer is no. The FX-9590 is a fun piece of hardware history and a decent upgrade for a very specific niche, but it's not a smart buy in 2025 unless you know exactly what you're getting into.
