Core i5-5575R

2015

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Iris Pro Graphics 6200, while Xeon E3-1505L v5 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E3-1505L v5 across 50 shared CPU benchmark tests.
❌Lower PassMark (5,074 vs 5,083).
❌Smaller total L3 cache (4 MB vs 8 MB).
❌Less compelling for workstation-style loads than Xeon E3-1505L v5, which brings 4 cores / 8 threads.
❌Launch MSRP is still $265 MSRP, while Xeon E3-1505L v5 mostly shows up through inconsistent older-market listings.

Xeon E3-1505L v5

2015

Why buy it

✅Better for gaming: +6.0% higher average FPS across 50 shared CPU benchmark tests.
✅+100% larger total L3 cache (8 MB vs 4 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 8 threads.
✅Draws 25W instead of 65W, a 40W reduction.

Trade-offs

❌No integrated graphics, while Core i5-5575R can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon E3-1505L v5 better than Core i5-5575R?

Not really, because they are built for different jobs. Xeon E3-1505L v5 makes more sense for workstation-style multi-core throughput, while Core i5-5575R 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 E3-1505L v5 is the better pick. According to our tests, it delivers 6.0% 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 E3-1505L v5 is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).

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

Xeon E3-1505L v5 is the easy recommendation for a fresh desktop build. Xeon E3-1505L v5 comes in at an unclear MSRP at unclear MSRP versus $265 MSRP, and it still gives you a 6.0% average FPS lead across 50 shared CPU game tests in our data. Core i5-5575R 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 6.0% in the shared gaming data.

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

Xeon E3-1505L v5 makes more sense long term for 2026 and beyond. You are getting 100% larger total L3 cache (8 MB vs 4 MB) and more multi-core headroom with 4 cores / 8 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
