Intel cancels Core Ultra 9 290K Plus after benchmark leak shows modest gains

Image credit: Intel

Intel announced the Arrow Lake refresh in early 2024 with a three‑tier stack: Core Ultra 7 270K Plus, Core Ultra 9 290K Plus, and a lower‑end 260K. While the 270K Plus shipped in Q2, the 290K Plus vanished from the roadmap. A Chinese reviewer recently obtained an engineering sample and ran a full suite of synthetic, productivity, and gaming tests. The data reveal why the flagship never reached market shelves.

Technical specifications of the 290K Plus

Feature	Core Ultra 7 270K Plus	Core Ultra 9 290K Plus (sample)
Core count	24 (8P+8E)	24 (8P+8E)
Base / Boost (P‑cores)	2.8 GHz / 5.2 GHz	3.0 GHz / 5.4 GHz
Base / Boost (E‑cores)	2.0 GHz / 4.0 GHz	2.2 GHz / 4.2 GHz
L3 cache	36 MB	36 MB
Memory support	DDR5‑6600	DDR5‑7200
Process node	Intel 20 nm (Intel 7)	Intel 20 nm (Intel 7)
New features	–	Arrow Lake Refresh binary optimizer, higher DDR5 speed

The sample confirmed the presence of Intel’s binary optimization tool that only activates on Arrow Lake refresh silicon, indicating the chip is genuine. Apart from a modest clock bump and faster DDR5 support, the silicon is otherwise identical to the 270K Plus.

Benchmark findings

Synthetic workloads

• CPU‑Z multi‑core: 19,546 vs 19,007 pts (+2.84 %)
• Cinebench R24 single‑core: 146 vs 145 pts (+0.69 %)
• Geekbench 6 multi‑core: 24,273 vs 23,642 pts (+2.67 %)
• Average across all synthetic tests: +1.5 % over the 270K Plus

Productivity and professional apps

• Ansys Fluent: 9.3 % faster than AMD Ryzen 9 9950X3D2 and 4.6 % ahead of the 270K Plus
• Compression, rendering, compiling: 2‑4 % gains over the 270K Plus, but still 8‑9 % behind the 9950X3D2
• Overall productivity average: +6.3 % vs 270K Plus, –8.3 % vs AMD flagship

Gaming performance (1080p)

• Delta Force: +8.3 % average FPS, +3.3 % 1 %‑low
• Counter‑Strike 2: +1.1 % average FPS
• PUBG: +2.1 % average FPS
• Black Myth: Wukong / Resident Evil 9: –1 % relative to 270K Plus
• Average across six titles: ≈+2 % FPS

Gaming performance (1440p)

• Delta Force: +6.8 % average FPS, +14 % 1 %‑low
• Other titles: within ±1 % of the 270K Plus
• Overall 1440p gain: ≈+1.5 % FPS

The numbers paint a consistent picture: the 290K Plus is a tiny step up in both single‑threaded and multi‑threaded workloads, with the most noticeable uplift in a single professional simulation (Ansys Fluent). In gaming, the advantage shrinks further as resolution rises and the GPU becomes the bottleneck.

Market implications

Pricing pressure

Intel’s Core Ultra 9 290K Plus would have sat at a premium price point, likely $1,300‑$1,500 USD, to differentiate it from the 270K Plus (around $950). A 2 % performance delta would not justify a 30‑40 % price premium, especially when AMD’s Ryzen 9 9950X3D2 offers 8‑10 % higher scores at a comparable cost.

Product‑line balance

The Core Ultra family already covers a broad performance‑to‑price spectrum:

• Core Ultra 7 270K Plus – high‑end mainstream
• Core Ultra 9 285K – the existing top‑tier Arrow Lake refresh
• Core Ultra 9 290K Plus – a marginally faster SKU that would have created a pricing gap between the 285K and AMD’s 3D‑V‑Cache CPUs. By scrapping the 290K Plus, Intel avoids cannibalizing sales of the 285K and keeps the lineup tidy for OEMs planning tiered pricing.

Supply‑chain considerations

Arrow Lake refresh chips are fabricated on Intel’s 20 nm “Intel 7” node, which is already operating near capacity for the 285K production run. Adding a new SKU would require a separate mask set for the clock‑bumped silicon and validation of DDR5‑7200 memory compatibility. With the modest performance delta, the incremental fab cost and validation effort likely outweighed any marginal revenue.

Competitive positioning

AMD’s 3D‑V‑Cache‑enabled Ryzen 9 9950X3D2 continues to dominate the high‑end desktop segment, delivering 8‑10 % higher scores in most benchmarks. Intel’s decision to stick with the 285K as the flagship keeps the Core Ultra brand competitive on price while focusing on other differentiators such as Intel Thread Director and Xe‑HPG integrated graphics for future generations.

What this means for consumers

• Current Core Ultra buyers can expect the 270K Plus to remain the top‑end Arrow Lake refresh offering, with a price‑to‑performance ratio that still looks attractive against AMD’s 3D‑V‑Cache parts.
• OEMs will not need to redesign thermal solutions or motherboard power delivery for a new 290K Plus SKU, simplifying inventory and reducing the risk of SKU fragmentation.
• Future Intel roadmaps will likely focus on the upcoming Meteor Lake and later “Intel 4” nodes, where larger architectural changes can deliver double‑digit performance gains rather than incremental clock bumps.
