The 5 Best LGA 1151 CPUs in 2024 for Building a Modern Desktop on a Budget

As an experienced system builder and long-time hardware analyst, processors hold a special place in my heart. And while fancy new platforms like LGA 1700 with Intel‘s latest Raptor Lake chips now exist, I believe older sockets like LGA 1151 still have a lot to offer savvy builders today.

In 2024, opting for an LGA 1151 motherboard and compatible CPU lets you craft formidable PCs at budget prices. Thanks to abundant inventory on the secondary market, going this route can either save you hundreds upfront or let you allocate more money toward a higher-end GPU.

The History and Value of LGA 1151 in 2024

Let‘s quickly rewind though – the LGA 1151 socket debuted way back in 2015 with Skylake-based 6th generation Core series processors. Remember them?

What came next was a series of iterative improvements on 14nm as newer CPU architectures like Kaby Lake and Coffee Lake landed alongside GPU tech progress. Despite its age, LGA 1151‘s backbone still runs modern platforms just fine.

You gain features like:

  • DDR4 RAM Support
  • Access to quality budget motherboards
  • 6 core and 8 core processors
  • M.2 NVMe storage compatibility

PCIe 3.0 is no doubt aging too as graphics cards and SSDs push the limits of available bandwidth – but it remains entirely capable for high FPS 1080p and 1440p gaming, which is what most gamers continue to target.

And thanks to used CPUs and open box motherboard deals, building a new LGA 1151 desktop with performance that can still rival modern setups has never been more affordable.

Let‘s explore some stellar chip options for doing exactly that while keeping costs in check. I‘ll be drawing from my own expertise having assembled over 30 personal rigs across multiple generations.

Ranking the Top 5 LGA 1151 CPUs for Performance and Value

To compile my list of favorite LGA 1151 processors for 2024 builds, I revisited performance benchmarks and specification comparisons while also keeping real-world gaming usefulness, streaming versatility and content creation viability in mind as tie-breaking considerations.

Like with any build, identifying realistic performance targets and budget limitations is pivotal to selecting well-suited components too. For example, the i9-9900K is very enticing but overkill for solely 1080p 60fps gaming driven by a lower-cost GPU like the RTX 3060 Ti. There are better ways to allocate funds in such cases!

With all that said, these are the Top 5 CPUs I wholeheartedly recommend for LGA 1151 platforms today and why:

1. Best Overall: Intel Core i9-9900K

  • 8 Cores, 16 Threads
  • Up To 5.0 Ghz Turbo
  • 16 MB Cache

Rationale: Thanks to abundant inventory from being released over 4 years ago, pricing has settled well under the original $530 MSRP. Because of that, Intel’s former flagship still provides the absolute pinnacle of gaming, streaming and multi-tasking performance without compromise that LGA 1151 supports today.

With eight hyper-threaded cores humming along at turbo speeds beyond 5Ghz, it can practically run laps around any other chip from the socket in both single and multi-threaded applications. And thanks to a high core count plus copious cache, overall 1% lows and frame time consistency see a notable bump over 6 core models too. That leads to smoother gaming experiences overall.

Looking purely at benchmark output, the i9-9900K is neck and neck with even modern mid-range Ryzen 5000 chips in theMETRICS that indicate real-world enjoyment and quick PC responsiveness.
