Intel Arrow Lake Review: Is the Ultra 9 285K Worth It in 2025?

Intel’s Arrow Lake architecture marks a bold attempt to reclaim desktop CPU dominance through redesigned cores and improved efficiency.

Intel needed a hero after a decade of unchallenged dominance in the CPU market. A resurgent Ryzen had already landed some strong blows, and a self-inflicted PR disaster in the wake of Raptor Lake left Team Blue battered and bruised in 2024.

A new socket, a new process node, and even a new identity were meant to help Intel shake off the last few years of bad results and make a fresh start. Yet, almost a year later, every new build recommendation still seems to revolve around AMD. But is it too soon to count Intel out?

A Look at the Arrow Lake Generation

The first enthusiast to hear about the new tile-based Intel Arrow Lake generation was the desktop 200 series, codenamed Arrow Lake. Early reports weren't encouraging. According to launch data, the Ultra 9 285K was a step backward in performance from the self-destructing i9s of the Raptor Lake generation. It couldn’t compete with AMD in gaming.

However, that was a year ago. Since then, BIOS updates, including the new 200S Boost overclocking profile, and the availability of high-speed CUDIMM memory have changed the landscape. Now might be the right time to revisit the Ultra 9 and see if these improvements make it worth buying in 2025.

Core Specifications and Design

The Core Ultra 9 285K is a 24-core CPU with 24 threads. Intel's latest strategy drops hyperthreading (or SMT) and replaces it with additional E-cores. The 285K still features eight performance cores, fabricated using the Intel 3 process, potentially for lower power consumption.

The P-cores have a base frequency of 3.22GHz and can boost up to 5.7GHz, while the 16 efficient cores run at 3.2GHz and can boost up to 4.6GHz.

The P-cores have access to a 36MB pool of Level 3 cache, while the E-cores only use Level 1 and Level 2 cache. Alongside these cores, Intel includes an integrated graphics processor, the ARXE LPG, with 64 execution units running at 2GHz.

While iGPUs are often overlooked, Intel's remain popular among video editors and media streamers. The Intel QuickSync standard supports hardware encoding and decoding for nearly every major video format, often outperforming even dedicated GPUs in this regard.

Platform and Memory Support

One more thing that stands out about the 200 series platform is that it works with CUDIMM memory modules. These DDR5 modules have built-in clock drivers, allowing them to run at higher speeds with greater stability. We tried out a kit that ran at 8000MTS right out of the box and could be overclocked even further.

The Ultra 9 285K was paired with an Asus ROG Strix Z890 motherboard, 48GB of Corsair CUDIMM memory, and an RTX 5090 to eliminate GPU bottlenecks. Everything was powered by a Corsair HX1200 PSU and cooled by an Arctic Freezer 3 280 mm.

Test Lineup and Comparisons

We compared the 285K to several other CPUs:

Ryzen 9 7950X3D: 12 cores with multi-threading and AMD's 3D V-Cache on half the cores.
Ryzen 7 7800X3D: The former best gaming CPU in the world.
Ryzen 7 7700: A productivity-focused CPU offering strong value.

Since the Ryzen CPUs can't use the CUDIMM's clock driver, we used DDR5-6000 CL36 memory.

Gaming Performance

Battlefield 6 at 1080p low with DLSS Quality achieved 230fps on average, suitable for a 240Hz display. Enabling 200S Boost raised this by about 4%, though the benefit was modest. Compared to Ryzen CPUs, it fell between the 7700 and 7900X3D (running with six cores).

In CS2, using a real-world Deathmatch on Dust 2 at 1080p low, the 285K reached 326fps without boost and only slightly more with boost. Ryzen's X3D chips, however, still outperformed it by 10–20%.

Moving to The Last of Us Part II at 1080p Very High with DLSS Quality, the 285K averaged 177fps, gaining 6% in boost mode. Here, the Ultra 9 matched the 7800X3D, while other CPUs trailed behind.

In Spider-Man 2, at the Very High preset, the 285K achieved 149 fps, rising to 165 fps with boost enabled—a 10% improvement. Even with Ultimate Ray Tracing enabled, it averaged 99 fps (105 fps with boost), beating the 7800X3D.

Cyberpunk 2077 proved challenging, with the CPU limited to around 100fps regardless of settings. The 7800X3D maintained a 10% lead, though the Ryzen 7700 offered similar value.

Space Marine 2 averaged just over 80 fps on the 285K, with an 8% improvement with boost. Most AM5 chips capped at around 90 fps, while only the 7800X3D broke 100 fps.

Baldur's Gate 3 delivered 130–139 fps depending on boost settings, comparable to the Ryzen 7700 but not outstanding given the Ultra 9's higher price.

Disabling the E-cores offered no real performance advantage. In fact, Cyberpunk dropped by up to 15%, while other titles saw slight decreases.

Productivity and Content Creation

In DaVinci Resolve, rendering a 5-minute 4K 60fps timeline took 3 minutes 18 seconds, making the 285K about a minute faster than the Ryzen chips. Even in Blender's Classroom scene, it completed in just 2 minutes 12 seconds—faster than any previous test result and over a minute quicker than a 12th-gen i9. However, boost mode had no positive impact here.

Synthetic benchmarks told a similar story. In Cinebench 24, the 285 K's multi-core score was 50% higher than the 7900X3D and double the 7800X3D, while single-core scores remained 20% higher than AMD's best. In Geekbench 6, the 285K maintained a 10% single-core and 20% multi-core lead over the 7950X3D.

Boost mode, however, proved inconsistent. It provided up to 4% gains but sometimes saw slight performance declines. Intel even admits it's not guaranteed to work on all chips.

Power Consumption and Efficiency

Performance aside, the 285 K's biggest drawback is its power draw. The impressive Cinebench results were achieved at a peak of 247W. By comparison, the Ryzen 7800X3D peaked at 120W. That 50% higher performance required more than 100% extra power. Although more efficient than the 13900K, Intel still trails AMD significantly in performance per watt.

For users unconcerned about energy costs, this may not matter. But for those mindful of power bills or thermals, this inefficiency adds to the real cost of ownership.

Final Thoughts

The Intel Core Ultra 9 285K is great for getting work done, offers strong single-core performance, and performs okay in games. But it struggles to compete with AMD's X3D line in gaming performance and price-to-performance.

The 285K has significant power draw and unpredictable boost performance, which makes it hard to market to gamers, even though BIOS updates and CUDIMM memory compatibility make it more stable and faster.

For content creators or professionals who rely on heavy rendering and encoding, the 285K is an impressive powerhouse. But for most gamers, Ryzen's efficiency and gaming optimization remain the smarter choice.

In short, Intel's Ultra 9 285K is brutally fast yet equally power-hungry, essentially the CPU equivalent of a high-performance Hummer: loud, powerful, and undeniably American in spirit.
