Quick Answers

So, is Core i5-5675R better than Core i7-2600K?
Yes. Core i5-5675R is the better overall CPU here. You are getting a 1.5% average FPS lead across 2 shared CPU game tests in our data, 1.5% 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 i5-5675R is the better pick here. According to our tests, it delivers 1.5% more average FPS across 2 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-5675R is the better fit. You are getting 1.5% better PassMark, backed by 4 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-5675R is the smarter buy by a wide margin for a fresh build. Core i5-5675R is 6.9% more expensive on MSRP at $339 MSRP versus $317 MSRP, and it gives you a 1.5% average FPS lead across 2 shared CPU game tests in our data. Core i7-2600K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2011 platform. Even with 5.4% better value on paper (17.3 vs 16.4 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1155.
Which one is more future-proof for 2026 and beyond?
Core i5-5675R is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2011) and more multi-core headroom with 4 cores / 4 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.
