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 i7-5775R

2015

Why buy it

  • +1.1% higher PassMark.

Trade-offs

  • Smaller total L3 cache (6 MB vs 8 MB).
  • 85.7% higher power demand at 65W vs 35W.
  • No integrated graphics, while Core i7-7700T can still boot and troubleshoot without a discrete GPU.

Core i7-7700T

2017

Why buy it

  • +33.3% larger total L3 cache (8 MB vs 6 MB).
  • Draws 35W instead of 65W, a 30W reduction.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Intel HD Graphics 630, while Core i7-5775R needs a discrete GPU.

Trade-offs

  • Lower PassMark (7,517 vs 7,598).
  • Launch MSRP is still $303 MSRP, while Core i7-5775R mostly shows up through inconsistent older-market listings.

Quick Answers

So, is Core i7-5775R better than Core i7-7700T?
Yes. Core i7-5775R is the better overall CPU here. You are getting a 1.1% average FPS lead across 2 shared CPU game tests in our data and 1.1% better PassMark, which makes it the stronger all-around choice.
Which one is better for gaming?
For gaming, the two CPUs are effectively a wash in the available data.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-5775R is the better fit. You are getting 1.1% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-5775R is the smarter buy by a wide margin for a fresh build. Core i7-5775R is at an unclear MSRP at unclear MSRP versus $303 MSRP, and it gives you a 1.1% average FPS lead across 2 shared CPU game tests in our data. Core i7-7700T only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (24.8 vs 0.0 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.
Which one is more future-proof for 2026 and beyond?
Core i7-7700T is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2015) and 33.3% larger total L3 cache (8 MB vs 6 MB). That makes it the safer long-term pick.

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.
