Intel’s new Arrow Lake structure, aka the Core Extremely 200S sequence, brings AI capabilities onto Intel desktops. However the chip doesn’t use the Copilot+ capabilities of Intel’s cellular Lunar Lake chip — its designers used the older NPU discovered on Meteor Lake as an alternative.
For now, which means that in case you purchase an Arrow Lake chip, you gained’t be capable of use it with a number of the new AI enhancements discovered inside Home windows 11’s 2024 Replace, like generative AI and the controversial Recall perform. Arrow Lake’s optimized NPU 3 solely supplies 13 TOPS, whereas Microsoft set 40 TOPS because the bar for Copilot+ standing. Intel nonetheless plans to ship greater than 40 million AI PCs in 2024, utilizing the vaguer “AI PC” definition that accompanied the launch of Meteor Lake.
Arrow Lake is the not the primary desktop PC structure to incorporate an NPU for AI. Final January, AMD introduced the Ryzen 8000 sequence of desktop processors with an NPU able to 39 TOPS. Nonetheless, the blink-or-you’ll-miss-it Ryzen 8000 was shortly changed by the Ryzen 9000 processor six months later in June — with out an NPU, however ushering in Zen 5 with a potent 16 % efficiency enchancment over the prior technology. Neither the Ryzen 8000 nor Arrow Lake meets the edge to be referred to as a Copilot+ PC.
Arrow Lake, like Meteor Lake, is a disaggregated structure — a elaborate identify for a modular design. Theoretically, couldn’t Intel have simply made extra of the 45 TOPS NPU 4 discovered inside Lunar Lake, and added it to the Arrow Lake bundle? Sure…and no, Intel executives mentioned.

Gordon Mah Ung additionally dived deeper into the 285K’s efficiency in productiveness workloads within the deep-dive video beneath:
Preserving it easy
First off, Arrow Lake’s NPU is similar NPU 3 as Meteor Lake, Robert Hallock, an Intel vice chairman and normal supervisor of consumer AI and technical advertising and marketing at Intel, instructed reporters.
“So we’ve had a lot of time to learn it and optimize it, and it made sense that we would fit this in,” he mentioned. (Meteor Lake’s NPU generated 11.5 TOPS, whereas Arrow Lake’s optimized model produces 13 TOPS.)
Nonetheless, Intel’s buyer base of fanatics additionally indicated that they didn’t need to hand over sure options, like a potent GPU, to verify the field of AI. And Intel, which confronted stress to ship Arrow Lake on time, discovered it simpler to simply use a longtime design.
“We actually had a long, a really long chat internally about how to allocate the transistor budget on this part,” Hallock continued. “To be clear, yes, it was fully possible to put a 50 TOPS, 40 TOPS NPU on this product, but to do so would also require shrinking the core count, changing the GPU core count. You start making sacrifices in sort of fundamental performance dimensions that enthusiasts really care about — that didn’t feel like the right mix. And we also talked at length about sort of the enthusiast market’s disposition on AI as a whole. And I think it’s fair to say it’s somewhat reluctant.”
Intel
As a substitute, Intel believes that software program builders aren’t all the time utilizing AI {hardware} successfully, {that a} mixture of elements (CPU, GPU, and NPU) is healthier than an NPU alone, and varied AI fashions are being successfully compressed sufficiently small that they don’t want an enormous NPU. All instructed, Arrow Lake-S (the Core Extremely 200S sequence) has a complete of 36 platform TOPS. Though Arrow Lake has an built-in GPU, many purchasers will pair the chip with a discrete GPU, which supplies much more AI horsepower than simply the NPU alone.
“We’ve proven that Meteor Lake’s 13-TOPS NPU is more than enough,” Hallock mentioned. “We’ve got enthusiast users who are somewhat skeptical, and so we sized an NPU that kind of fits all of those constraints while preserving and protecting the CPU performance that people care about most and still gives enough AI to embrace workloads that are coming down the pipe.”
Apparently, Intel will debut two cellular chips within the Arrow Lake household through the first quarter of 2024. One, code-named Arrow Lake-HX, will primarily be a cellular copycat of the Core Extremely 200S chips that Intel will start delivery in a couple of weeks. A second household of Arrow Lake-H chips for notebooks supplies many extra TOPS total than Arrow Lake-S or -HX: 99 platform TOPS in all. Nonetheless, these will come from a beefed-up GPU that makes use of XMX extensions and extra Xe cores. The NPU will nonetheless present 13 TOPS.
Roger Chandler, vice chairman and normal supervisor for fanatic PC and workstation product advertising and marketing at Intel, reiterated what Hallock mentioned — that software program builders aren’t utilizing the complete capabilities of the prevailing NPUs successfully. Intel’s objective, he mentioned, was to supply a “balanced platform.”
“When I look at AI right now, we’re like, 10 seconds into a 20-hour movie,” Chandler mentioned.
