Quick Answers

So, is Ryzen Embedded R1505G better than Athlon X4 845?

It depends on what you want from the system. For gaming, Athlon X4 845 is ahead with a 10.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Ryzen Embedded R1505G pulls ahead with 0.8% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Ryzen Embedded R1505G is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 4 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Ryzen Embedded R1505G is still the much better call for a fresh build. Ryzen Embedded R1505G comes in 14.3% more expensive on MSRP at $80 MSRP versus $70 MSRP, and it still gives you 0.8% better PassMark. Athlon X4 845 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2016 platform. Even with 13.4% better value on paper (53.8 vs 47.5 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on FM2+.

Which one is more future-proof for 2026 and beyond?

Ryzen Embedded R1505G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2016) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
