AMD A-Series APU 7800 4-core Socket FM2+

The AMD A10-7800 is a $34 USD used quad-core APU with integrated Radeon R7 graphics and a 65W TDP. It's a solid choice for reviving an old FM2+ system or building a cheap HTPC, with 4K output and light gaming capability. Performance is well behind modern chips, landing in the low 30s percentile for both single and multi-thread. Only buy it if you already have the motherboard and RAM to support it.

The raw numbers tell a clear story. PassMark puts this at 3212 multi-thread and 1450 single-thread. For context, a modern budget chip like the Intel Core i3-14100F absolutely crushes those numbers, but it also costs several times more. The A10-7800's 3.5GHz base and 3.9GHz turbo across four cores is enough for web browsing, office work, and media playback without much fuss. The 4MB of L2 cache is actually a decent chunk for a chip this old, and it helps keep everyday tasks feeling snappy.

The integrated Radeon R7 graphics are the wildcard. This is one of the stronger iGPUs from the DDR3 era, and it can handle older titles and esports games at low settings. The 4K support is a real plus if you're building a cheap home theater PC. Just don't expect miracles. The efficiency score in our database is a mediocre 38th percentile, and the platform ranking is even lower at 39th. You're working with DDR3 memory and PCIe limitations that will hold back any modern GPU you try to pair with it.

The Intel Core i3-14100F is the obvious modern alternative, and it's not even close on performance. That chip has much higher single-thread and multi-thread scores, but it also requires a new motherboard, DDR4 or DDR5 RAM, and a discrete GPU since it has no integrated graphics. You're looking at a completely different budget tier. The A10-7800 wins on total cost if you already have the platform, and it wins on having usable graphics built in.

The Dell Xeon E5-2637 V2 is an interesting comparison from the used market. That chip offers better multi-thread performance for server-style workloads, but it's a different socket, pulls more power, and has no integrated graphics worth mentioning. For a basic desktop or HTPC, the A10-7800 is the more practical choice. The be quiet! and Thermal Grizzly entries in our competitor list are coolers, not CPUs, so they're not really in the same conversation. The HP ProLiant is a server platform, which tells you how broad our database is, but it's not a realistic alternative for a desktop buyer.

At $34 USD, this is hard to argue with if you already have an FM2+ motherboard and DDR3 RAM. You're getting a quad-core chip with a capable iGPU for less than the cost of a decent pizza night for two. The affordability percentile backs this up, and for a used part with a boxed cooler, it's a genuinely low-risk purchase.

The value equation falls apart if you're building from scratch. A used FM2+ board, DDR3 sticks, and this APU might total $80 to $100, and at that point you're within striking distance of a used Ryzen 3 or older Intel setup that will run circles around it. The efficiency and platform scores in our database are both below average, so you're buying into a dead end. Fine for a repair or a cheap secondary box, not for a foundation.

The AMD A10-7800 is a blast from the recent past, a quad-core APU from the Kaveri era that still pops up in budget builds and used listings. We're looking at a used unit going for about $34 USD, which immediately tells you this isn't a chip for people chasing the latest frame rates. It's for someone who needs a working desktop on a tight budget, or someone resurrecting an old FM2+ board that's been sitting in a closet.

What makes this interesting is the integrated Radeon R7 graphics. Back when this launched, the whole pitch was that you could skip a discrete GPU and still get playable performance in lighter games and smooth 4K video output. The 65W TDP also means it won't turn a small case into a toaster, and the boxed cooler is a nice touch if you're buying used and don't have a spare heatsink lying around.

But let's be real about what this is in our database. The multi-thread score lands in the 32nd percentile and single-thread in the 31st, so it's well behind modern budget chips. The affordability ranking is the real story here, sitting at the 94th percentile. You're buying cheap, functional computing, not a performance bargain.

Skip this if you're building a new system from scratch, even on a tight budget. The FM2+ platform is a dead end, DDR3 memory is slow by modern standards, and the performance ceiling is low. You'd be better off saving a bit more for a used Ryzen 3 or an older Intel i3 setup that has an actual upgrade path.

Also skip it if you're hoping to pair it with a modern graphics card. The PCIe limitations and weak single-thread performance will bottleneck anything remotely current. This chip is for integrated graphics use cases, not as a foundation for a discrete GPU build. If you want to game with a dedicated card, look at a used Ryzen or Intel platform instead.

If you've got an FM2+ board sitting around and you need a cheap chip to bring it back to life, the A10-7800 is a no-brainer at $34 USD. It'll handle browsing, streaming, office work, and even some light gaming without complaint. The integrated Radeon R7 graphics are the saving grace here, making it a genuinely useful all-in-one solution for a budget HTPC or a kid's first PC.

For anyone starting a new build, even a budget one, look elsewhere. The platform is dead, the performance is dated, and the money you'd spend on used FM2+ parts would be better put toward a used Ryzen or Intel setup. This chip is a repair part, not a foundation. Buy it to fix something, not to build something.
