Intel 270K Plus vs 285K: Budget CPU that Beats a Flagship

Intel is launching the Arrow Lake Refresh CPUs, and honestly, it is quite exciting. It is not the fastest CPU available, but it stands out as one of the best price-performance CPUs seen in a long time, and also one of the best Intel launches in recent years.

There is the Intel 250K Plus, a CPU with 6P cores and 12E cores for about €200, and the Intel 270K Plus with 8P cores and 16E cores for about €300. This essentially means that the 270K Plus delivers performance comparable to a Intel 285K but at €200 less. There are only small differences, but surprisingly, in testing, the 270K Plus was 4% faster than a 285K, making it a very interesting CPU overall.

High-End PSU for Demanding Systems

The CIC Prime PX 2200 is currently one of the strongest PSUs available. It comes with two native PCIe5.1 connectors, allowing native support for GPUs like the NVIDIA RTX 5090. This makes it perfect for overclocking systems or high-end workstations.

The PSU delivers excellent quality and performance, with very flexible cables, included cable combs, and even a 90°ATX24pin adapter that doubles as a PSU tester. The fan operates in a semi-passive mode and remains very quiet even under high load.

A Refreshing Intel Launch Approach

Intel had already talked about the specs of the 200S Plus CPUs, and Robert Hallock's presentation was one of the best product introduction videos in the business. Instead of too much marketing, the focus stayed on technical details, clear explanations, and clarity.

To avoid confusing naming schemes, the new CPUs include a "Plus" at the end of their names to show that they are refresh models.

Core Configurations and Performance Positioning

The 250K Plus has 18 cores, and the 270K Plus has 24 cores, which are a mix of P and E cores. Intel says that the new models are far faster than the old ones, but it's not always easy to compare them because the cores are set up differently. A clearer comparison comes when looking at competitors like the AMD Ryzen 7 9700X in the same price range.

Intel’s strategy becomes clear here. Claims like +100% multi-threading performance are valid because the 270K Plus effectively delivers 285K-level performance at a much lower price. The differences between the 270K Plus and 285K are minimal, mainly involving slight clock variations.

Frequency and Memory Improvements

The refresh brings several big improvements, such as a 900MHz increase in the die frequency, a 100MHz increase in the E-core clock, and officially supported memory speeds that are 400MHz faster. The 270K Plus can use memory speeds of up to 7200MT/s, whereas the 285K without boost features can only use speeds of up to 6400MT/s. The P-core clocks are 100 MHz slower, and the E-core clocks are 100 MHz faster.

Although the 285K includes additional features like Thermal Velocity Boost, testing shows minimal real-world advantage from these additions.

Workstation Motherboard and Cooling Setup

Testing was performed on the ASUS ProWS Z890-ACE, a workstation-focused motherboard with a rotated socket layout. The memory sits at the top, and the VRM and EPS connectors are positioned differently from typical gaming boards.

It includes a BMC controller, multiple Ethernet ports including 10G and 2.5G, and is clearly designed for professional workloads rather than gaming.

For optimal thermals, the stock Intel ILM was replaced with an 1851 contact frame, and a custom water cooling loop was used. The cooling block has a protective inlet filter that keeps particles from getting stuck in the fins, which keeps the performance stable over time.

Power Consumption and Thermal Performance

With bespoke water cooling, the 270K Plus uses about 220W and keeps temps around 70°C when running Cinebench R23. The P-cores work at 5.4GHz, and the E-cores work at 4.7GHz. This results in nearly 44000 points in multi-threaded performance.

In clean runs, the CPU consistently reaches about 44000 points at 223W, making it around 4% faster than the 285K. Similar behavior appears in 3DMark CPU Profile tests, where it is 5% faster but consumes about 10% more power at 163W.

Real-World Performance and Productivity

In real-world tasks like Adobe 4K video rendering, performance is nearly identical to the 285K. Given the significantly lower price, this makes the 270K Plus extremely attractive for productivity workloads. Multi-threaded performance is where this CPU truly excels, outperforming competing AMD CPUs in this segment.

Gaming Performance Analysis

Gaming performance remains a mixed experience. In titles like Counter-Strike2, improvements are noticeable compared to earlier Arrow Lake CPUs, but AMD processors with 3D V-Cache still lead. In other games such as Star Wars Outlaws, performance is already strong and comparable to the 285K.

In Cyberpunk 2077 at 1080p, CPUs like the AMD Ryzen 9 9950X3D still perform better. But at 4K resolution, when GPU limits are the most important, the difference in performance between CPUs is really small.

Platform Limitations and Upgrade Concerns

The LGA1851 platform is a big problem. It won't be able to handle future updates because subsequent CPUs will use a different socket. This means that if you choose this platform, you have to be okay with not being able to upgrade it very often. AMD's AM5 platform, on the other hand, has a longer upgrade path.

Final Thoughts

The 270K Plus is a great pick for €300 if you don't care about being able to upgrade it. It performs almost as well as a flagship model but costs a lot less, especially when it comes to multi-threaded applications.

It is encouraging to see Intel moving in this direction, bringing stronger competition back into the CPU market and setting the stage for future developments.
