Intel Core Ultra 7 268V vs AMD Ryzen Z2 Extreme

Intel Core Ultra 7 268V

The Intel Core Ultra 7 268V is a higher-end Lunar Lake family processor. This is an SoC for use in tablets and laptops of the slimmer kind that was unveiled in Autumn 2024. It sports 4 new Skymont E-cores and 4 new Lion Cove P-cores running at up to 3.7 GHz and 5.0 GHz respectively, along with the new Arc 140V iGPU and 32 GB of on-package LPDDR5x-8533 RAM. A new 48 TOPS neural engine, Thunderbolt 4 and PCIe 5 SSD support are included as well. A vPro-enabled version of the CPU became available in early 2025.

The only difference between this chip and the Ultra 7 266V is the amount of on-package, non-replaceable RAM: 32 GB vs 16 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 much higher at 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 268V has a very healthy 12 MB of level 3 cache; elsewhere, it 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 48 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

The 268V should be just a couple of percentage points faster than the 258V for an Core Ultra 7 165U or Core i7-1360P-like multi-thread performance, provided it's running at the default long-term TDP power target which is 17 W.

Generally speaking, the 288V, 268V, 266V, 258V, 256V are faster than the 238V, 236V, 228V and 226V due to the difference in their last-level cache size (8 MB vs 12 MB) 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%. It depends on the TDP figures of the laptops being pitted against each other more than on anything else.

Graphics

The Arc Graphics 140V is here to replace the Arc 8 iGPU. Its 8 Xe² architecture "cores" run at up to 2,000 MHz and it also has 8 ray tracing units at its disposal. The adapter is DirectX 12 Ultimate-enabled and able to HW-decode a long list of popular 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.

All 2023 and 2024 games are playable at 1080p on low graphics settings or higher with this iGPU. We got well over 30 fps in Ghost of Tsushima and almost 40 fps in Baldur's Gate 3. This means the Radeon 780M gets left behind while the Radeon 890M reigns supreme.

Power consumption

This 2nd generation Core Ultra processor is supposed to consume 17 W when under long-term workloads. The Intel-recommended short-term power limit for the chip sits at 37 W.

AMD Ryzen Z2 Extreme

The Ryzen Z2 Extreme is a relatively powerful Strix Point family processor that debuted in early 2025. The hybrid architecture APU has 8 CPU cores onboard (a mix of three Zen 5 and five Zen 5c cores) running at 2.0 to 5.0 GHz, along with the 16 CU RDNA 3.5 Radeon 880M graphics adapter and the 50 TOPS XDNA 2 neural engine. Compared to the similar Ryzen AI 7 PRO 360, the Z2 Extreme does not offer the Ryzen AI NPU.

Architecture and Features

Strix Point family APUs are powered by Zen 5 and Zen 5c microarchitecture cores found in two separate clusters, the latter being a slightly slower, smaller and more energy-efficient version of the former. One of the differences between Zen 5 and Zen 5c is cache size; Zen 5 cores have larger caches to work with.

Either way, mobile Zen 5 implementation is reportedly (ChipsAndCheese) closer to desktop Zen 4 than to desktop Zen 5 due to differing cache sizes, vast differences in AVX-512 throughput and other factors.

Elsewhere, the Ryzen chip supports DDR5-5600 and LPDDR5x-8000 RAM, giving system designers a choice between lower latency and higher throughput respectively. The chip is natively compatible with USB 4 (and therefore Thunderbolt). It has PCIe 4.0 support for a throughput of 1.9 GB/s per lane, just like its 8000 series predecessors did. The integrated XDNA 2 NPU, which is a lot more complex than first-gen XDNA was, delivers up to 50 INT8 TOPS for accelerating various AI workloads.

As is usual for mobile CPUs, the Ryzen 7 AI PRO chip is not user-replaceable as it gets soldered down for good.

Performance

The performance should be similar to the Ryzen AI 7 PRO 360 due to the similar specs, but limited due to TDP and heat restrictions in handhelds.

Graphics

The Radeon 880M is the direct successor to the 780M. It packs several differences under the hood, such as faster caches; its 16 RDNA 3.5 architecture CUs/WGPs (768 unified shaders) run at a currently undisclosed clock speed. With well over 30 fps in both Once Human and The First Descendant (1080p - Low), this AMD iGPU is usually certainly fast enough for a fair bit of casual as well as competitive gaming.

Power consumption

The Z2 Extreme is supposed to have a low-term TDP power target of 28 W, with handheld makers free to set between 15 and 35 W. 

The 4 nm TSMC process that these CPUs are built with makes for above average, as of late 2024, energy efficiency.
