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

Core i7-6700T

2015

Why buy it

  • +33.3% larger total L3 cache (8 MB vs 6 MB).
  • Costs $114 less on MSRP ($303 MSRP vs $417 MSRP).
  • Delivers 38.4% more PassMark for each dollar spent, at 23.1 vs 16.7 PassMark/$ ($303 MSRP vs $417 MSRP).

Trade-offs

  • Less compelling for workstation-style loads than Xeon E3-1265L v4, which brings 4 cores / 8 threads and 16 PCIe lanes.
  • No integrated graphics, while Xeon E3-1265L v4 can still boot and troubleshoot without a discrete GPU.

Xeon E3-1265L v4

2015

Why buy it

  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads, plus 16 PCIe lanes vs 0.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Iris Pro Graphics P6300, while Core i7-6700T needs a discrete GPU.

Trade-offs

  • Lower PassMark (6,954 vs 6,994).
  • Smaller total L3 cache (6 MB vs 8 MB).
  • Lower PassMark per dollar, at 16.7 vs 23.1 PassMark/$ ($417 MSRP vs $303 MSRP).

Quick Answers

So, is Core i7-6700T better than Xeon E3-1265L v4?
Not really, because they are built for different jobs. Xeon E3-1265L v4 makes more sense for workstation-style multi-core throughput, while Core i7-6700T is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
If gaming is the priority, Core i7-6700T is the better pick. According to our tests, it delivers 0.1% 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, Core i7-6700T is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-6700T is the better buy right now. Core i7-6700T comes in $114 cheaper on MSRP at $303 MSRP versus $417 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. It is also 38.4% better value on MSRP (23.1 vs 16.7 PassMark/$), 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 i7-6700T makes more sense long term for 2026 and beyond. You are getting 33.3% larger total L3 cache (8 MB vs 6 MB) 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.
