See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core i7-4790K

2014

Why buy it

✅Better for gaming: +15.7% higher average FPS across 50 shared CPU benchmark tests.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics 4600, while Xeon E3-1535M v6 needs a discrete GPU.

Trade-offs

❌Lower PassMark (8,063 vs 8,077).
❌Launch MSRP is still $350 MSRP, while Xeon E3-1535M v6 mostly shows up through inconsistent older-market listings.
❌95.6% higher power demand at 88W vs 45W.

Xeon E3-1535M v6

2017

Why buy it

✅+0.2% higher PassMark.
✅Draws 45W instead of 88W, a 43W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-4790K across 50 shared CPU benchmark tests.
❌No integrated graphics, while Core i7-4790K can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon E3-1535M v6 better than Core i7-4790K?

Not really, because they are built for different jobs. Xeon E3-1535M v6 makes more sense for workstation-style multi-core throughput, while Core i7-4790K 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, Xeon E3-1535M v6 is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E3-1535M v6 is still the much better call for a fresh build. Xeon E3-1535M v6 comes in at an unclear MSRP at unclear MSRP versus $350 MSRP, and it still gives you 0.2% better PassMark. Core i7-4790K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 100.0% better value on paper (23.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.

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

Xeon E3-1535M v6 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2014) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
