Intel BX806733104

The Xeon Bronze 3104 is one of the slowest CPUs we've ever tested, landing in the bottom 3-4% for single-thread, multi-thread, and efficiency. It only makes sense if you need the absolute cheapest chip for an existing LGA3647 server board. For everyone else, skip it.

The numbers are rough. Single-thread performance lands in the bottom 3% of all CPUs we've tested, which means even basic tasks feel sluggish. Multi-thread isn't much better at the 4th percentile, and with no hyperthreading those six cores run out of steam fast. Efficiency is somehow worse, sitting at the 4th percentile, so you're getting very little work done per watt. The 85W TDP isn't crazy high, but the performance per watt is abysmal. AI workloads? Forget it. That score is a 4.2 out of 100, dead last in our charts.

Stacked against the AMD Ryzen 7 9800X3D, this Xeon looks like it's from another planet. The Ryzen has eight cores, modern architecture, and gaming performance that's off the charts, while the 3104 sits in the bottom 3% for single-thread. The Core i9 BX80673I99960X is another LGA3647 chip but with way more cores and clock speed, so it's the obvious upgrade path if you're stuck on that socket. Even the old E5-2697 v2, a chip from 2013, has more threads and better multi-thread throughput. The only reason to pick the 3104 is if you find it for pocket change and just need something to boot a server.

Pricing is all over the place. In Europe you'll see it listed anywhere from EUR 244 to EUR 388 depending on the vendor, and that spread is wild for a chip this old. The best deal in our data comes from the DE listings at the EUR 244 end. But honestly, even at the low end you're paying for a CPU that gets smoked by used desktop chips costing half as much. Unless you specifically need LGA3647 for an existing server board, this is hard to justify.

The Intel Xeon Bronze 3104 is a server chip from a bygone era trying to hang on in 2025. Six cores, no hyperthreading, and a 1.7GHz base clock that feels glacial next to anything modern. It's built for cheap dual-socket servers, not your desktop, and it shows in every benchmark we ran.

Our database puts this thing in the bottom 5% for single-thread, multi-thread, and efficiency. That's not a typo. If you're looking at this for anything other than a very specific budget server build, you're probably in the wrong aisle.

Skip this if you need any kind of responsive performance. If you're building a home server, a used Ryzen or even an old Xeon E5 v2 will run circles around it for less money. And if you're thinking about gaming, streaming, or any AI tinkering, this chip is a hard pass. The only buyer who should consider it is someone with an LGA3647 board already in hand and a budget so tight it squeaks.

This is a niche chip for a niche buyer. If you have an LGA3647 board sitting around and need the cheapest possible CPU to get it running, the Bronze 3104 will do that. But for anything else, even light home server duty, there are better options for less money. It's slow, inefficient, and outclassed by hardware that's over a decade old.
