AMD FX 99999 8-core AM3+

The AMD FX-8320E is an 8-core AM3+ CPU that still works for heavily threaded tasks on old motherboards, but its single-thread performance is weak and the platform is dead. It only makes sense as a drop-in upgrade for existing AM3+ systems. For new builds, modern budget CPUs are a much better use of your money.

The PassMark scores are 5138 multi-thread and 1442 single-thread. For context, that multi-core number lands around the 41st percentile in our database, which is solidly middle of the pack for older CPUs but nowhere near modern chips. The single-thread score is the real problem. At the 31st percentile, it falls behind most processors from the last several years, and that hurts in games and everyday desktop tasks that lean on one or two fast cores.

The 8 cores and 8 threads sound impressive on paper, and for heavily threaded workloads like video encoding or running multiple VMs, the FX-8320E can still chug along. But the per-core performance is weak by today's standards. The 4.0GHz boost helps a bit, but the 32nm Vishera architecture is just old. Efficiency is also rough, sitting around the 40th percentile. The 95W TDP is better than the 125W original, but it's still a lot of power for the performance you get. AI and LLM workloads are the weakest area at 27 out of 100, so don't expect this to handle any modern machine learning tasks gracefully.

The FX-8320E gets compared to a lot of newer silicon, and the gap is brutal. Against something like the Intel Core Ultra 7 265KF, there's no contest. The Ultra 7 is on a completely different planet for single-thread, multi-thread, and efficiency. Even older Intel chips like the Xeon E5-2637 V2 hold up better in specific server-oriented tasks, though that's a different socket and use case entirely.

One comparison that comes up a lot in the reviews is against budget Intel parts like the Pentium G4560. Several buyers point out that the G4560 matches or beats the FX-8320E in most games while using far less power and costing less. That's a fair point. The FX-8320E only makes sense if you already own an AM3+ board and need more cores for productivity without replacing the whole platform. If you're building from scratch, even a modest modern CPU will embarrass this thing in games and daily use.

Value is tricky here because the price depends entirely on where you shop. At USD 148 in the US, it's a questionable buy unless you specifically need an AM3+ drop-in upgrade. The EUR pricing is the real head-scratcher. We saw listings from EUR 272 to EUR 368 across DE, ES, and IT. The cheapest EUR listing at EUR 272 is still a lot of money for a chip this old, and the EUR 368 listing is frankly hard to justify. If you're in Europe and dead set on this CPU, hunt down the EUR 272 option and avoid the higher-priced stores. For most people, that money goes much further on a used Ryzen or even a budget modern platform.

The AMD FX-8320E is an old-school 8-core CPU from the Vishera era, built on a 32nm process and designed for the AM3+ socket. It runs at 3.2GHz base with a 4.0GHz boost and carries 8MB of L2 plus 8MB of L3 cache. In our database it sits in a weird spot: it's not really a budget king anymore, and it's definitely not a modern performer. But it still has a fanbase, mostly people keeping older AM3+ systems alive or hunting for a cheap upgrade path.

If you're searching for an affordable 8-core processor for an older motherboard, this is one of the few options that drops straight into AM3+ boards. The 95W TDP is lower than the original FX-8320's 125W, which made the E variant popular for smaller builds and quieter coolers. But that efficiency comes at a cost, and the numbers below tell the story pretty clearly.

We pulled pricing from a few regions and it's all over the place. You'll see it listed around USD 148 in the US, GBP 188 in the UK, and CAD 407 in Canada. In Europe the spread is wild, from EUR 272 up to EUR 368 depending on the store. That's a huge gap for a chip this old, so where you buy matters a lot.

Skip the FX-8320E if you're building a new PC, playing modern games, or doing any kind of AI or machine learning work. The single-thread performance will frustrate you in daily use, and the platform has no future. If you need a cheap productivity chip, look at used Ryzen 5 or Intel Core i5 parts from the last few generations. They'll cost less in the long run and run circles around this old Vishera chip. Also skip it if you're in Europe and can't find a listing near the EUR 272 mark, because paying EUR 368 for this CPU is a genuinely bad deal.

Should you buy the AMD FX-8320E in 2025? Only if you have a very specific situation: an existing AM3+ motherboard, a need for 8 threads on the cheap, and no interest in a full platform upgrade. For that narrow use case, it's a drop-in fix that can extend the life of an old system. The 95W TDP also makes it a slightly more sensible choice than the original FX-8320 if you're worried about heat or power.

For everyone else, no. The single-thread performance is a real drag on everyday responsiveness and gaming. The platform is dead, there's no upgrade path, and the European pricing especially is hard to swallow. You'd be better off saving for a used Ryzen 5 or a budget Intel build. This chip was a decent budget option a decade ago, but time has not been kind.
