When you’re looking at the current landscape of the desktop processor market, you have to ask yourself one major question. How does a giant like the blue team carry on innovating when they aren’t currently sitting on the throne? If the competition is holding onto that gaming crown with an iron grip by way of the 9850X3D and the majority of the enthusiast user base is looking elsewhere for their raw frames, you really only have a couple of options. You can either go back to the drawing board for a total architectural overhaul, or you can do what Intel has done today by taking an existing formula, refining the absolute life out of it, and pushing the hardware further for the current generation, and that’s what we’re looking at today with the Core Ultra 7 270K Plus and Core Ultra 5 250K Plus.
Intel Core Ultra

So today we’re diving deep into what looks to be a very aggressive pivot from Intel with the launch of the new Intel Core Ultra 5 250K Plus and the Core Ultra 7 270K Plus processors. Now, don’t let that “Plus” branding lead you to believe this is just a minor sticker update. While these are technically refreshes of the Arrow Lake platform, Intel is positioning these as their fastest gaming desktop processors to date, aiming to act as the ultimate revolution of this architectural generation.
It’s a move we’ve seen time and time before, not just from Intel, but from AMD too. You take a solid architectural foundation, you apply some serious process refinements, you bin the silicon a lot more aggressively to squeeze out every extra megahertz, and you slap a new badge on the box. Tadah! We’ve seen this before, but Intel isn’t just bumping clock speeds and calling it a day like we’ve seen AMD do with the likes of the 9850X3D. They are instead calling this “pioneering performance technology” for gamers, and looking at the spec sheet, they are making some bold claims, though of course, this could just be marketing fluff.

Let’s start by talking about the heavy hitter first, the Core Ultra 7 270K Plus. This chip comes in with 24 cores in an 8P+16E core configuration with 24 threads so an increase of 4 efficiency cores. Intel has also pushed the boost clock up by 100MHz to 5.5GHz, which is a modest jump over the “vanilla” model, but the real secret sauce, and the thing I suspect is going to be the most impactful for enthusiasts, is the inclusion of an up to +900 MHz D2D (Die-to-Die) frequency increase tightening up the interface that connects the SoC and compute tiles. When you’re dealing with a tile-based architecture, the speed at which those different pieces of silicon talk to each other is critical, and Intel is betting that this frequency bump is going to streamline performance in a way we haven’t seen before, though again, before we get testing, this could be a nothingburger and just be a sensationalist headline grabber. We also see the L3 cache being bumped up for 30MB of shared cache to 36MB in the hope of bridging the gap with AMD’s X3D models that feature almost 3 times the amount of cache in a stacked configuration.

Also launching today is the Core Ultra 5 250K Plus. This mid-range CPU is packing 18 cores (6P+12E) and 18 threads, with a max boost clock of 5.3 GHz, which again is a modest 100MHz increase. It also gets that same +900 MHz D2D frequency treatment and a 6MB bump in L3 cache from 24MB, now up to 30MB. On paper, Intel is touting some significant numbers here, as their marketing bumf claims this chip can deliver up to 2x the multithreaded performance of the competition’s Ryzen 5 9600X in specific workloads.

Beyond that, for both processors, they remain pretty unchanged with the same TDP and same PL1 and PL2 values, though we do see an increase in supported rated memory speed from 6400MT/s, now up to 7200MT/s, and Intel did send a 7200MT/s kit with our press samples, but for the sake of being fair, we tested using the same 6800MT/s kit that we’ve tested all other Intel processors with, though we may look and doing some testing with that kit at a later date.

Now, to understand where these “Plus” chips sit, we have to look at what they are replacing. The original Core Ultra 7 265K and Core Ultra 5 245K were solid, but Intel felt there was more on the table. In terms of raw gaming performance, Intel’s internal testing shows the 270K Plus delivering an average 15% increase over the 265K, while the 250K Plus offers a 13% jump over the 245K. These aren’t just minor gains; they represent a serious attempt to refine the platform for enthusiasts who want more performance for the same socket and of course, helps to bridge the gap with X3D parts from AMD.

A significant part of this performance story comes down to the cache that I spoke about. While the core architecture remains unchanged, Intel has refined the subsystem to ensure these high-frequency cores are never starved for data. By pushing the D2D frequency up by 900 MHz, they are essentially widening the lanes between the compute tiles and the cache, allowing for much lower latency when hitting that massive pool of memory. This refined cache behavior is exactly what’s driving those double-digit gaming gains as reported by Intel.

Intel is also doubling down on software as well with the introduction of their all-new Binary Optimisation Tool (iBOT). This is an optional feature within their Application Optimisation policy that uses a new class of optimisation IP to streamline library and executable performance. The goal here is to reduce architectural contention, basically making sure that the CPU isn’t tripping over its own feet when trying to process complex game code. Intel is claiming this can lead to notable gains in gaming, with their internal slides showing up to a 39% uplift in Shadow of the Tomb Raider and a 22% jump in Hitman 3, though we’re not using this for our testing, as we’re more focussed on out of the box performance to make a fairer comparison.

The real “mic drop” moment of this launch, however, is the price. Intel is coming out swinging with a “more performance per dollar” strategy this time around. The Core Ultra 5 250K Plus is launching at just $199, while the Core Ultra 7 270K Plus arrives at $299. When you consider the performance these chips are aiming for, those price points are designed to be highly disruptive in the current market, which has arguably stagnated, and isn’t exactly what I’d call booming right now. The standout here though is the price disparity with the predecessors, which came in at $319 and $394 for the Core Ultra 5 245K and Core Ultra 7 265K when they launched back in October of 2024.

This is a pretty clear signal that Intel is looking to reclaim ground in the all important enthusiast segment. They’re aggressively positioning these PLUS variants to provide better value while still offering enthusiast-grade features like early support for quad-rank CUDIMM memory on select 800 Series motherboards, though I do wonder how big this technology will be as it becomes widely available.

So, the questions we’re looking to answer today are pretty simple. Are these gains reflected in our own testing? Can this refresh close the gap with the current gaming leader? And what does this mean for your next build? Along with that, when you’re not changing the fundamental architecture, and using the same process node, but packing more in, what does it mean for cooling and power draw metrics? Well we’ve tested it all to find out exactly what’s going on so that you’re ready for the 26th March sales date.
