Last month Intel began shipping the Intel Core Ultra 7 270K Plus "Arrow Lake Refresh" desktop processor. This is a mighty interesting processor for the $349 USD price point with more cores and a larger cache compared to the Core Ultra 7 265K and capable of delivering much of the performance of the flagship Core Ultra 9 285K Arrow Lake processor. In today's article is a look at how well the Intel Core Ultra 7 270K Plus performs under Linux with more than 340 different benchmarks representing a range of Linux workloads from gaming to creator to developer and technical computing uses.

The Intel Core Ultra 7 270K Plus features 24 cores between eight P cores and 16 E cores. This "Arrow Lake Refresh" SKU features a 5.5GHz turbo / TBMT 3.0 frequency, 3.7GHz P core base frequency, 36 MB Intel Smart Cache, and a 125 Watt base power rating with 250 Watt turbo power rating. Intel launched the Core Ultra 7 270K Plus with a recommended customer price of $289 USD but as of writing all the major online listings have it for $349 USD, which is still priced competitively for how well this CPU is performing.

The Core Ultra 7 270K Plus has the same 24 core layout as the Core Ultra 9 285K flagship while the max turbo frequency on the 285K is 200MHz higher (5.7GHz) while the 270K Plus does have the advantage of its E core max turbo frequency being 100MHz higher at 4.7GHz.

Another advantage to the Core Ultra 7 270K Plus is support for up to DDR5-7200 MT/s memory compared to DDR5-6400 MT/s memory with the original Arrow Lake processor SKUs.

Unfortunately, my Intel Core Ultra 7 270K Plus (and 245K Plus) review samples weren't shipped out until after the review embargo had already lifted. The delay combined with being in the middle of re-testing all the CPUs under the new Ubuntu 26.04 LTS operating system with the Linux 7.0 kernel meant this delay in delivering these benchmarks. My apologies but now you have 300+ benchmarks across a wide swath of workloads and all under the very leading-edge Ubuntu 26.04 with Linux 7.0. The CPUs (re)tested for today's comparison included:

- Core Ultra 5 245K

- Core Ultra 7 270K Plus

- Core Ultra 7 270K Plus w DDR5-7200

- Core Ultra 9 285K

- Ryzen 5 9600X

- Ryzen 7 9700X

- Ryzen 7 9800X3D

- Ryzen 7 9850X3D

- Ryzen 9 9900X

- Ryzen 9 9950X

- Ryzen 9 9950X3D

Unfortunately I was never supplied any Core Ultra 7 265K review sample from Intel which is why that close sibling isn't part of the comparison. The Core Ultra 5 245K Plus Linux testing is still being wrapped up with all the benchmarks taking close to two days per run, but should be published next week.

The Core Ultra 7 270K Plus was tested both at DDR5-6400 like the other Arrow Lake CPUs plus also using the new DDR5-7200 memory modules provided as part of the Intel review kit. Thanks to Intel for providing the review hardware for Linux testing at Phoronix.

Let's see how the Intel Core Ultra 7 270K Plus is performing under Linux with Ubuntu 26.04 + Linux 7.0 up against all of these other Arrow Lake and AMD Zen 5 desktop processors not only in raw performance but also CPU power efficiency and value.
