Quick Answers

So, is Core i5-1035G1 better than Core i5-7640X?

It depends on what matters more to you. For gaming, Core i5-7640X is ahead with a 18.8% average FPS lead across 4 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-1035G1 pulls ahead with 2% better Cinebench R23 multi-core.

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

For streaming, content creation, and heavier multitasking, Core i5-1035G1 is the better fit. You are getting 2% better Cinebench R23 multi-core, backed by 4 cores and 8 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i5-1035G1 is the smarter buy by a wide margin for a fresh build. Core i5-1035G1 is at an unclear MSRP at unclear MSRP versus $249 MSRP, and it gives you 2% better Cinebench R23 multi-core. Core i5-7640X only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (28.4 vs 0.0 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA2066.

Which one is more future-proof for 2026 and beyond?

Core i5-1035G1 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2017) and more multi-core headroom with 4 cores / 8 threads instead of 4/4. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
