Ryzen Embedded R1505G

2019

Why buy it

✅Draws 15W instead of 85W, a 70W reduction.
✅100+% more PCIe lanes (8 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon Vega 3, while Xeon E5-2603 v3 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5-2603 v3 across 50 shared CPU benchmark tests.
❌Lower PassMark (3,799 vs 3,825).
❌Smaller total L3 cache (4 MB vs 15 MB).
❌Less compelling for workstation-style loads than Xeon E5-2603 v3, which brings 6 cores / 6 threads.
❌Launch MSRP is still $80 MSRP, while Xeon E5-2603 v3 mostly shows up through inconsistent older-market listings.

Xeon E5-2603 v3

2014

Why buy it

✅Better for gaming: +10.0% higher average FPS across 50 shared CPU benchmark tests.
✅+275% larger total L3 cache (15 MB vs 4 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 6 threads.

Trade-offs

❌466.7% higher power demand at 85W vs 15W.
❌No integrated graphics, while Ryzen Embedded R1505G can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon E5-2603 v3 better than Ryzen Embedded R1505G?

Not really, because they are built for different jobs. Xeon E5-2603 v3 makes more sense for workstation-style multi-core throughput, while Ryzen Embedded R1505G is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon E5-2603 v3 is the better pick. According to our tests, it delivers 10.0% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon E5-2603 v3 is the stronger fit. You are getting 0.7% better PassMark, backed by 6 cores and 6 threads. It also has the larger cache pool with 275% larger total L3 cache (15 MB vs 4 MB).

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

Xeon E5-2603 v3 is the easy recommendation for a fresh desktop build. Xeon E5-2603 v3 comes in at an unclear MSRP at unclear MSRP versus $80 MSRP, and it still gives you a 10.0% average FPS lead across 50 shared CPU game tests in our data. Ryzen Embedded R1505G only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 10.0% in the shared gaming data.

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 2014). That makes it the safer long-term bet.
