Intel Core Ultra 5 250K Plus review: The new best $200 CPU

Intel wants to change the narrative around its Arrow Lake CPUs. That’s the goal with Core Ultra 200S Plus, with Team Blue trying to earn back some slots among the best gaming CPUs that it’s lost, both to AMD and its own previous-gen offerings over the past 18 months. The $200 Core Ultra 5 250K Plus is targeting budget-conscious builders, taking the fight to AMD’s entry-level 6-core offerings and bringing down the Core Ultra 5 brand a tier in pricing.

We’ve already looked at the Core Ultra 7 270K Plus, which is Intel’s $300 offering in this small range of Arrow Lake Refresh CPUs. And the story here is similar to what we saw with the Core Ultra 7. Intel is delivering some of the best productivity performance we’ve seen in several generations, considering the price, and a decent, albeit still lacking, improvement in gaming performance.

The weakness on the gaming front is a bit easier to forgive here, however, given how far away the price is from dominant X3D chips like the Ryzen 7 7800X3D and Ryzen 7 9850X3D. The Core Ultra 5 250K Plus is particularly compelling if you don’t have a Micro Center nearby, which continues to offer the Ryzen 5 7600X3D at $200; at present, there isn’t another CPU even remotely close as far as gaming value goes.

Looking at the overall performance picture, the Core Ultra 5 250K Plus is great, with the productivity performance doing some heavy lifting. My main reservation about an all-out recommendation is the platform. The LGA 1851 socket is on its way out, and Intel has teed up next-gen Nova Lake CPUs for the end of this year. Even with clear advantages over AMD’s Zen 5 competition, the AM5 socket will see support through at least the end of 2027.

We have a full range of benchmarks to show the capabilities of the Core Ultra 5 250K Plus in action, including an updated suite of 17 games, as well as application tests ranging from creative apps to chess engines. We’ll have some more on Intel’s interesting Binary Optimization Tool in the coming days, as well.

Intel Core Ultra 200S Plus ‘Arrow Lake Refresh’ pricing and specifications

Arrow Lake Refresh CPUs are indeed a refresh, but Intel tells me that it’s using an entirely new revision of the wafer, not just binning existing silicon. For the Core Ultra 5 250K Plus, it sits in a unique spot among the new Arrow Lake lineup, with 18 total cores split across six Lion Cove P-cores and 12 Skymont E-cores. It’s launching at $200, which is $109 less than the launch price of the Core Ultra 5 245K and the same price that you can find that chip at now.

Compared to the 245K, Intel packed in four extra E-cores, along with 10 MB of extra cache to accommodate. The P-cores see a slight 100 MHz bump up to 5.3 GHz on boost clock speed, while the E-cores have a 300 MHz cut on base frequency, though with the same turbo speeds. The 250K Plus carries the same TDP of 125W and MTP of 159W, and it comes with official support for memory up to 7200MT/s – a mark that even the lowly Core Ultra 5 225 can hit with ease.

Otherwise, Intel boosted the die-to-die frequency by 900 MHz, speeding up communication between the Compute tile and SoC tile, and bumped the fabric frequency by 400 MHz. The goal is to make up for arguably the weakest aspect of the Arrow Lake architecture out of the box: additional latency brought on by Intel’s first chiplet-based architecture. You can achieve these higher frequencies with Core 200S Boost on Z-series motherboards, but the bump with the Core Ultra 5 250K Plus comes stock, so you’ll get the same frequencies on B- and H-series motherboards.

Specs aside, the other big introduction with Arrow Lake Refresh is the Intel Binary Optimization Tool, or iBOT. We go into more detail about iBOT in our Core Ultra 7 270K Plus review, and we have a dedicated article on the feature coming soon. But we’ll give you a quick rundown of what it’s doing here so the testing makes sense.

IBOT is a translation layer along the lines of Apple Rosetta or Microsoft Prism. It’s just not translating instructions from one ISA to another. Instead, it’s optimizing how instructions run for a given architecture. For example, if there’s a cache miss because data is tagged improperly, iBOT allows Intel to step in at runtime and tag that data properly, effectively increasing IPC by avoiding major cache misses, branch mispredictions, and hardware interrupts.

This is the type of optimization a developer does before recompiling the binary. For Intel, it’s squeezing out extra performance by translating a general x86 binary to a binary specifically optimized for a given architecture. Intel can do this due to hardware registers within the chip that show what’s happening while code is executing. And, instead of changing the source code and recompiling, Intel is redirecting inefficiencies on a production binary at runtime via iBOT.

There are some potential downsides to iBOT. It’s adjusting code running in real-time, so it can throw up red flags to software like anti-cheat. Intel says iBOT operates in the same space as user applications, however; in other words, it doesn’t have kernel- or hardware-level access.
