CPU Comparison
Intel Core i5-750 vs Intel Core i7-2700K
A side-by-side comparison of specs, performance and value. The Intel Core i5-750 is a quad-core Lynnfield desktop processor that defined mainstream performance in 2009, offering four real cores on LGA 1156 without Hyper-Threading or integrated graphics.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Four cores help with basic multitasking but modern productivity apps will feel sluggish.
Adequate for basic office tasks and web browsing, but slow for modern rendering.
Gaming
With a discrete GPU, can handle older games but cannot run modern titles at acceptable frame rates due to CPU limitations.
Struggles with modern AAA titles but handles older or esports games fine.
Virtualization
Four real cores provide usable virtualization for lightweight VMs.
Can handle light VMs with 8 threads, but lacks modern virtualization features.
Efficiency
95W for four 45nm cores is inefficient by modern standards.
32nm process is highly inefficient by modern standards, drawing significant power.

Our Verdict on Each
A landmark processor that offered excellent quad-core value in 2009-2010. Completely obsolete today but historically significant as the processor that established the Core i5 brand.
Best for: Keeping an existing LGA 1156 Lynnfield system functional for light tasks
Read the full reviewA legendary CPU that still holds up for basic tasks, offering incredible historical value and overclocking fun.
Best for: The Core i7-2700K is no longer recommended for new PC builds due to its age and lack of modern feature support, such as native NVMe storage booting and modern PCIe standards. However, for users already operating on an LGA 1155 motherboard looking to squeeze more life out of an older system, finding a used 2700K can be a highly cost-effective upgrade path. It still handles basic computing, media consumption, and older game titles reasonably well. If you are building a system from scratch, modern alternatives offer vastly superior power efficiency, single-core speed, and platform features. Collectors and retro gaming enthusiasts might specifically value the chip for its historical significance, but mainstream buyers should look toward newer generations for a balanced, future-proof computing experience.
