In this blog post, we’ll dive into a detailed comparison, dissecting specs and performance potential. Get ready to discover if the latest KS chip justifies an upgrade, as anticipations run high for Intel’s upcoming powerhouse!

Core i9-14900KS vs. Core i9-12900KS: Specs comparison

The Core i9-14900KS is now official, with a confirmed launch date of March 14, 2024.  Leaked specs suggest it will be a significant upgrade over the i9-12900KS.

Let’s break down the key differences:

  • Core Power Unleashed: The i9-14900KS boasts 24 cores (8 performance, 16 efficiency) compared to the i9-12900KS’s 16 cores. This extra power translates to faster rendering, encoding, and smoother handling of demanding multitasking workloads.
  • Clock Speed Advantage:  While the i9-14900KS has a slightly lower base clock (3.2 GHz vs. 3.4 GHz), its boosted clock speed of 6.2 GHz is a noteworthy jump over the i9-12900KS’s 5.5 GHz. This could mean better single-core performance in tasks like gaming.
  • Cache Matters:  The i9-14900KS increases both its L2 and L3 cache sizes, potentially speeding up data access and improving overall efficiency.

Other considerations

  • Motherboard Compatibility: Ensure your motherboard supports the latest 14th generation Intel chips if considering the i9-14900KS.
  • Power & Cooling: Both CPUs have a TDP of 150W, meaning they’ll need robust cooling and power supplies.
  • Intel UHD Graphics: Don’t expect significant leaps in integrated graphics between the two generations. These CPUs will need dedicated graphics cards for serious gaming.

ArchitectureRaptor Lake RefreshAlder LakeNewer architecture could have efficiency gains

Here’s why:

  • More Cores, More Power:  The i9-14900KS’s rumored additional P-cores and a greater overall core count suggest major gains in multithreaded workloads like video editing, 3D rendering, simulations, and other demanding content creation tasks.
  • Clock Speed Boost:  The i9-14900KS’s potentially higher clock speeds (with enhanced Turbo Boost) could mean snappier everyday performance and higher gaming framerates (if your graphics card is potent enough).
  • Cache Advantage:  A larger L3 cache might help the i9-14900KS keep data close to its cores, which could boost efficiency and reduce loading times in various applications
  • Leaked Benchmarks: While we need official tests, leaked Cinebench scores suggest substantial gains for the i9-14900KS, demonstrating its potential as a powerhouse CPU suitable for professional-level workloads.

Beyond the specs

  • Architectural Improvements: Intel’s Raptor Lake Refresh architecture (on the i9-14900KS) likely includes efficiency improvements over the 12900KS’s older design, even if clock speeds were similar.
  • Overclocking Potential: Both these “KS” series CPUs are likely unlocked for overclocking, which could further boost performance, but risks stability and voids your warranty.
  • Competition from AMD: It’s crucial to see how AMD’s latest CPUs stack up against the i9-14900KS, as they often offer competitive performance and value.

Important note

These performance gains are based on leaks and rumors. We need official benchmarks on the i9-14900KS to confirm its true advantage over the desktop beast that is the i9-12900KS.

Core i9-14900KS vs. Core i9-12900KS: Price and value

The Core i9-14900KS, as Intel’s latest flagship processor, will likely command a premium price – potentially around $765.  This aligns with the launch price of the i9-12900KS.  Here’s how to decide if it’s worth it for you:

  • Who is it for? The i9-14900KS targets tech enthusiasts and professionals who need absolute peak performance. If you do heavy content creation (3D work, video editing, etc.), the extra cores and speed might be worth the investment if it translates to significantly faster rendering times.
  • The Value Factor: We need official benchmarks to see the  real-world performance gap between the two CPUs.  This will help determine if the i9-14900KS’s price justifies the gains.
  • Don’t Forget the Rest: Factor in costs for a compatible motherboard (if needed) and a robust cooler to handle the likely high-power draw of the i9-14900KS.
  • Potential Discounts:  Prices on older-gen CPUs like the i9-12900KS might drop as the i9-14900KS releases, making the i9-12900KS even more compelling for value seekers.
