Intel's CPU development journey, particularly with the LGA 1700 platform, marks a deviation from their traditional tick-tock strategy. Historically supporting only two series per platform, Intel now presents three generations on the same platform. This is a significant shift from their usual approach, especially considering their past challenges in maintaining long-term platform support.

Intel, once the dominant force in the CPU market, particularly for gaming, has seen its position challenged in recent years. The emergence of AMD's Ryzen series, offering competitive price-to-performance ratios, has significantly altered the market dynamics. Despite Intel's release of the 14th-gen Raptor Lake-refresh CPUs, they face growing challenges in the retail space.
AMD's success with the AM4 platform, despite initial missteps, has become a notable factor in the CPU market. AMD's commitment to comprehensive platform support with AM5, although with hints of a shorter lifecycle than AM4, contrasts with Intel's approach. This difference has contributed to the brighter prospects for AMD's platforms compared to Intel's LGA 1700.
The peak of LGA 1700's success arguably came with the launch of the 12th-gen Alder Lake architecture. The subsequent 13th-gen Raptor Lake update offered improvements like increased cache capacities and higher clock speeds, but these were not substantial enough to sway 12th-gen owners. In practice, 12th-gen CPUs could be overclocked to match 13th-gen frequencies, further diminishing the appeal of upgrading.
To objectively compare the 12th, 13th, and 14th-gen K-SKU parts, the testing methodology involved standardizing the clock speeds across all CPUs. The E-cores were disabled, and the ring bus was locked at 3GHz. All CPUs were tested using DDR5-7200 memory and a GeForce RTX 4090 GPU to ensure a consistent testing environment.
In the Cinebench multi-core benchmark, the performance increase from the 12th to 14th-gen models was marginal, with only a 3% improvement in clock-for-clock performance for the 14900K compared to the 12900K. The Core i7 models showed a similarly modest improvement, with just a 2% increase from the 12th to 14th-gen and a 1% increase for the 14600K over the 12600K. This data suggests that the architectural changes in recent generations have resulted in only incremental performance gains.
