Intel Core Ultra 5 226V

The Intel Core Ultra 5 226V is one of the 2 slowest Lunar Lake family processors as of Nov 2024. This is an SoC for use in tablets and laptops of the slimmer kind that was unveiled in Autumn 2024. It features 4 new Skymont E-cores and 4 new Lion Cove P-cores running at up to 3.5 GHz and 4.5 GHz respectively, along with the new Arc 130V iGPU and 16 GB of on-package LPDDR5x-8533 RAM. A new 40 TOPS neural engine, Thunderbolt 4 and PCIe 5 SSD support are included as well.

The only difference between this chip and the Ultra 5 228V is the amount of on-package, non-replaceable RAM: 16 GB vs 32 GB respectively.

Architecture and Features

Lunar Lake is built using the Foveros technology (stacking several dies on top of each other and next to each other), just like Meteor Lake was. The new chips make use of the enormous BGA2833 socket interface. Of the 8 cores, not a single one is Hyper-Threading-enabled which is the opposite of what AMD currently does with its Zen 5/5c chips.

Intel claims Lion Cove cores bring a 14% IPC improvement over Redwood Cove. For Skymont and Crestmont, the difference is a staggering 68%. Several tweaks and improvements are present here, such as the Low Latency Fabric that is supposed to make small data transfers between cores/caches a lot faster. The 226V's level 3 cache is pretty small as compared to more expensive Ultra 7 2xxV and Ultra 9 2xxV chips at 8 MB vs 12 MB. Elsewhere, the 226V has 4 PCIe 5 and 4 PCIe 4 lanes for connecting various kinds of devices, including NVMe SSDs at up to 15.75 GB/s. Thunderbolt 4 support is onboard by default, as is support for CNVi WiFi 7 + BT 5.4 cards from Intel. The 40 TOPS "AI Boost" neural engine is present along with technologies such as Threat Detection to make AI-enabled applications such as the Windows Defender more powerful.

Intel is predicted to get short of on-package RAM in subsequent CPU generations.

Performance

Our in-house testing of an Acer laptop powered by the Ultra 5 chip revealed the latter to be about as fast as the Ryzen 7 7730U and the Ryzen 7 7735U in multi-threaded tasks which is OK but not mind-blowing for late 2024. It is worth noting that the laptop in question does not use the Intel-recommended 17 W long-term power target; instead, the processor gets 30 W to eat which affects its benchmark scores significantly.

Generally speaking, the 226V, 228V, 236V and 238V are slower than the 256V, 258V, 266V, 268V, 288V due to the difference in their last-level cache size as well as clock speeds. However, the difference in performance between the slowest Lunar Lake chip, the 226V, and the fastest chip, the 288V is fairly small at around 10% to 15%. Exact figures depend on the TDP values of the laptops being pitted against each other more than on anything else.

Graphics

The Arc Graphics 130V has 7 Xe² architecture "cores" running at up to 1,850 MHz, as well as 7 ray tracing units at its disposal. This is a direct successor to the Arc 7 iGPU; it is DirectX 12 Ultimate-enabled and able to HW-decode a long list of video codecs such as h.266 VVC, h.265 HEVC, h.264 AVC, AV1 and VP9. Three SUHD 4320p monitors can be used simultaneously with this iGPU.

Its performance can be vastly different depending on which benchmarks and games one runs. Oftentimes, it isn't much faster than its direct predecessor, the Arc 7. It is clear the 130V isn't fast enough to run most triple-A 2024 games at 1080p. However, it's still more than good enough for an occasional gaming session.

• Helldivers 2: 25 fps (Med, 1080p). The Arc 7 and the Radeon 880M deliver similar results.
• Ready or Not: 40 fps (Med, 1080p). The GeForce MX350 delivers a similar result.

Power consumption

While this 2nd generation Core Ultra processor is supposed to consume 17 W when under long-term workloads, the only laptop powered by this chip that we have tested as of early Nov 2024 has a much higher value than that at 30 W.

The Intel-recommended short-term power limit for the chip sits at 37 W.
