The 9950X features a substantial 64MB of L3 cache shared across its 16 cores, complemented by 16MB of L2 cache. The 285K implements a different cache hierarchy with 36MB of shared L3 cache and 40MB of total L2 cache distributed differently between P-cores and E-cores.
Memory support also differs notably, with the 9950X officially supporting DDR5-5600 while the 285K supports DDR5-6400, giving Intel a theoretical bandwidth advantage here. The 285K also supports CUDIMMs, whereas the AMD processor does not. Both processors support up to 192GB of memory across dual channels with ECC capability.
When we move on to platform integration and connectivity, it reveals the maturity difference between AMD's established AM5 ecosystem and Intel's new LGA1851 platform. The 9950X operates within AMD's mature AM5 socket, supporting a wide range of chipsets from budget A620 to flagship X870E options, with extensive motherboard choices and competitive pricing.
Intel's 285K requires the new LGA1851 socket exclusively with Z890 chipset support initially, though B860 and H810 options are also available now. Power consumption specifications show the 9950X with a 170W TDP and 230W maximum boost power, while the 285K features a lower 125W base power rating but can consume up to 250W under maximum turbo conditions.
The 285K also integrates Intel's first desktop NPU, providing 13 TOPS of AI performance and enhanced integrated graphics with 64 execution units, features absent from the 9950X's basic dual-core Radeon graphics implementation.
⭐Winner: Tie
There is not much to separate the two CPUs at the end of the first round. Both CPUs have their advantages on paper, but they ultimately cancel each other out. The Core Ultra 9 285K has support for faster memory and a unique NPU, while the Ryzen fights back with more threads and L3 cache.

Overclocking: AMD Ryzen 9 9950X vs Intel Core Ultra 9 285K
AMD's approach to overclocking targets user-friendliness and efficiency within thermal and power limits. The Ryzen 9 9950X leverages AMD's Precision Boost Overdrive 2 (PBO2) technology and Curve Optimizer. PBO2 allows enthusiasts to relax power limits, letting the CPU's internal algorithms push frequencies higher automatically based on thermal headroom and workload.
The Curve Optimizer is a key strength, enabling fine-grained, per-core negative voltage offsets. This undervolting reduces heat and power consumption, often allowing sustained higher boost clocks without manually setting fixed high voltages or frequencies. AMD's platform generally offers robust memory overclocking support (EXPO) alongside CPU tuning.
While manual static overclocking is possible, the greatest gains often come from intelligently optimizing PBO2 and Curve Optimizer settings, which are less thermally demanding than brute-force voltage increases. AMD users can achieve performance gains through both automatic and manual tuning approaches; however, these gains can be comparatively limited due to the aggressive out-of-the-box tuning that delivers the lion's share of performance at stock settings.
Intel's Core Ultra 9 285K maintains the company's traditional strength in manual overclocking capabilities, offering extensive BIOS options and granular control over frequencies and voltages.
Intel now offers warrantied memory overclocking through its 200S Boost feature. While this feature doesn't offer much, if anything, beyond the gains seen with standard XMP memory overclocking, it does provide warranty protection for memory overclocking, a feature that AMD still doesn't offer. Intel also supports CUDIMM memory, which generally makes higher memory transfer rates more easily achievable with Intel processors, as opposed to the typical requirement of finding a cherry chip with an exceptional integrated memory controller (IMC).
Arrow Lake introduces new complexities with its Digital Linear Voltage Regulator (DLVR) technology and hybrid architecture combining P-cores and E-cores.
The DLVR system enables lower voltage operation but requires more sophisticated tuning compared to previous Intel generations. The 285K also features Thermal Velocity Boost (TVB) and Overclocking Thermal Velocity Boost (OCTVB) technologies that automatically adjust frequencies based on temperature conditions.
While these provide performance benefits, they can complicate manual overclocking efforts as they introduce additional variables to consider. Intel's approach traditionally offers more overclocking headroom in terms of raw frequency gains, but the Arrow Lake architecture's complexity means achieving optimal results requires more expertise than previous generations
Regardless, the Core Ultra 9 285K can achieve higher absolute frequencies and provides the hands-on tuning experience and the results that many hardcore overclockers prefer.
⭐Winner: Intel Core Ultra 9 285K
For manual overclocking enthusiasts who prefer traditional hands-on tuning, Intel's 285K provides more flexibility and overclocking headroom, while AMD's 9950X is also quite capable with its sophisticated automated boost technologies and user-friendly tuning tools. The 285K supports higher standard memory overclocks and supports CUDIMMs that lower the bar for bleeding-edge memory transfer rates. The pathway to warrantied memory overclocking also gives Intel the edge in this category.
Power Consumption, Efficiency, and Cooling: AMD Ryzen 9 9950X vs Intel Core Ultra 9 285K
Based on our comprehensive testing, the Core Ultra 9 285K demonstrates superior efficiency in low-utilization scenarios. During true idle states, it consumes just 16W, which is a 37.5% advantage for Intel.
This gap becomes more noticeable during active-idle tasks like YouTube playback, where the 285K uses a whopping 61% less power than the Ryzen 9 9950X. This efficiency stems from Intel’s hybrid architecture, which aggressively parks high-performance cores and delegates background tasks to low-power E-cores. In contrast, the Ryzen processor uses a central I/O die that can't be placed into an idle state, resulting in higher idle and active idle power consumption.
In sustained workloads, however, the power dynamic reverses sharply. During AVX-intensive stress tests like Prime95 Small FFTs, the 285K draws 325W, a staggering 40.7% higher than the 9950X's 231W. Similarly, in y-cruncher’s AVX workload, the Intel CPU consumes 31.7% more power than the AMD chip.
Even in rendering benchmarks like Cinebench 2024, the 285K was at a consistent 13% disadvantage to the Ryzen 9 in terms of power consumption. These differences highlight Intel’s reliance on higher voltage and clock speeds to maximize throughput, while AMD’s architecture and optimized core layout reduce power demands under load.
The Ryzen 9 9950X also excels in workload efficiency metrics. In the HandBrake x265 encoding test, it consumes 12.5% less watts per FPS than the Intel competitor. Cinebench 2024 further cements this advantage, where the 9950X delivers 7.8% better performance-per-watt than the 285K.
The HandBrake x265 task energy plot visually reinforces this point as well, positioning the 9950X closer to the "bottom-right" ideal (high fps, low energy), while the 285K resides higher on the energy axis. The AMD Ryzen 9 9950X delivers more FPS while consuming less task energy than the 285K in this particular workload.
Moreover, the Intel Core Ultra 9 285K’s higher power ceiling directly impacts thermal management. Its peak power draw of 325W in Prime95 demands robust cooling (likely a premium 360mm AIO or high-end air cooler) to prevent thermal throttling. Even a custom liquid cooling loop is not a bad option to consider if you can afford and maintain it.
In contrast, the 9950X’s 231W peak allows relatively effective thermal control with a high-quality 240mm AIO or dual-tower air cooler. You should consider investing in a good 360mm liquid cooler if you can afford it, but if your budget is tight, a well-built 240mm AiO will also suffice.
Summing up the power debate, while the Core Ultra 9 285K leads in idle/low-load efficiency, the Ryzen 9 9950X dominates under load with 10-40 % lower power consumption in multi-threaded benchmarks and 7-13% better performance per watt according to our testing.
Combined with its significantly lower peak power draw, AMD’s solution is more efficient for sustained workloads and easier to cool effectively.
⭐Winner: AMD Ryzen 9 9950X
For users prioritizing thermals, noise, and long-term power efficiency (especially in productivity or rendering scenarios), the 9950X offers a compelling advantage over the 285K.
