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 all-around CPU here. It gives you a 2.0% average FPS lead across 50 shared CPU game tests in our data and 1.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

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

For streaming, content creation, and heavier multitasking, Core i7-5775R is the stronger 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 still the much better call for a fresh build. Core i7-5775R comes in at an unclear MSRP at unclear MSRP versus $303 MSRP, and it still gives you a 2.0% average FPS lead across 50 shared CPU game tests in our data. Core i7-7700T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (24.8 vs 0.0 PassMark/$), it really only makes sense as a 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 makes more sense long term 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 bet.
