Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5-2603 v4 across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (6 MB vs 15 MB).
❌Less compelling for workstation-style loads than Xeon E5-2603 v4, which brings 6 cores / 6 threads.
❌Launch MSRP is still $338 MSRP, while Xeon E5-2603 v4 mostly shows up through inconsistent older-market listings.

Xeon E5-2603 v4

2016

Why buy it

✅Better for gaming: +6.0% higher average FPS across 50 shared CPU benchmark tests.
✅+150% larger total L3 cache (15 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 6 threads.

Trade-offs

❌Lower PassMark (4,517 vs 4,588).
❌466.7% higher power demand at 85W vs 15W.

Quick Answers

So, is Core i3-1115GRE better than Xeon E5-2603 v4?

Not really, because they are built for different jobs. Xeon E5-2603 v4 makes more sense for workstation-style multi-core throughput, while Core i3-1115GRE is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Core i3-1115GRE is the stronger fit. You are getting 1.6% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-1115GRE is the better buy right now. Core i3-1115GRE comes in at an unclear MSRP at $338 MSRP versus unclear MSRP, and it still gives you 1.6% better PassMark. The compromise is that Xeon E5-2603 v4 is still the better pure gaming CPU with a 6.0% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (13.6 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i3-1115GRE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2016), more multi-core headroom with 2 cores / 4 threads instead of 6/6, and AVX-512 support for heavier modern compute workloads. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
