About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, productivity performance, platform differences, power efficiency, pricing context, and upgrade path so you can see which CPU actually makes more sense.

Core i7-1180G7

2021

Why buy it

  • +100% larger total L3 cache (12 MB vs 6 MB).
  • Draws 9W instead of 65W, a 56W reduction.
  • 100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Iris Xe Graphics 96EU, while Core i7-5775C needs a discrete GPU.

Trade-offs

  • Fewer obvious downsides in this matchup outside of normal market pricing swings.

Core i7-5775C

2015

Why buy it

    Trade-offs

    • Lower PassMark (7,688 vs 7,788).
    • Smaller total L3 cache (6 MB vs 12 MB).
    • Launch MSRP is still $366 MSRP, while Core i7-1180G7 mostly shows up through inconsistent older-market listings.
    • 622.2% higher power demand at 65W vs 9W.
    • No integrated graphics, while Core i7-1180G7 can still boot and troubleshoot without a discrete GPU.

    Quick Answers

    So, is Core i7-1180G7 better than Core i7-5775C?
    Yes. Core i7-1180G7 is the better overall CPU here. You are getting a 2.1% average FPS lead across 5 shared CPU game tests in our data, 1.3% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.
    Which one is better for gaming?
    If gaming is the priority, Core i7-1180G7 is the better pick here. According to our tests, it delivers 2.1% more average FPS across 5 shared CPU game tests.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Core i7-1180G7 is the better fit. You are getting 1.3% better PassMark, backed by 4 cores and 8 threads. It also carries the larger cache pool with 100% larger total L3 cache (12 MB vs 6 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Core i7-1180G7 is the smarter buy by a wide margin for a fresh build. Core i7-1180G7 is at an unclear MSRP at unclear MSRP versus $366 MSRP, and it gives you a 2.1% average FPS lead across 5 shared CPU game tests in our data. Core i7-5775C only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (21.0 vs 0.0 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1150.
    Which one is more future-proof for 2026 and beyond?
    Core i7-1180G7 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2015), 100% larger total L3 cache (12 MB vs 6 MB), and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.

    Games Benchmarks

    Paired with RTX 4090

    To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

    Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
