Intel Arrow Lake processors to tackle Apple MacBook laptops with massive 320 EU Arc Battlemage GPU on TSMC’s 3nm process node


A major roadmap for Intel’s next-gen mobility platform that showcases the 15th-gen Arrow Lake processor lineup has been leaked by AdoreTV. In the roadmap, it is stated that Intel is pulling out all the stops in its next-gen mobility lineup, delivering a huge upgrade in GPU and CPU architecture.

Intel Arrow Lake Processor Roadmap Leaks: Targeting Late 2023 Production Window With TSMC-Based 3nm Arc Battlemage GPUs and Next-Gen Lion Cove Compute Cores

With Arrow Lake, it looks like Intel is prioritizing mobile first over desktop and although there are both Arrow Lake-S and Arrow Lake-P processors, the company is aiming to specifically produce its 15th generation mobility processors first to tackle Apple’s next generation. 14″ MacBook laptops. Based on the leaked roadmap, it looks like we’ll see the first engineering samples ready by late 2022 and early 2023 with QS chips shipping in Q3 2023 and final production starting in the same quarter.And finally, the processors will be ready for RTS (Ready To Ship) in the fourth quarter of 2023. So this means that we are looking at a late 2023 or early 2024 launch for the Arrow Lake line of mobility processors new generation.

As for specs, the Intel Arrow Lake-P will be a Halo product and will be based on the brand new Lion Cove (P-Core) and Skymont (E-Core) which appear to use TSMC’s N3 process node. Intel’s recent Investor Day roadmap listed the use of ‘Intel 20A’ and ‘TSMC N3’ for Arrow Lake processors, so it appears that compute tiles that include the processor and GPU will use an external foundry node from TSMC while some SOC/IO IP will rely on Intel’s own 20A node. Although there has been a rumor that TSMC’s 3nm may slide its launch window and since the slide is a few months old, there is still some debate about the use of the N3 node in Arrow Lake-P processors.

Other details mention that the SOC/IOE-P B stage will be 100% reused from the Meteor Lake L/P SKUs since Arrow Lake is the sequel to the 14th Gen Meteor Lake chips. But the most important detail mentioned is that the Arrow Lake-P processors will use 6+8+3 configurations. This is a 6+8 (P-Core/E-Core) design bringing the number of cores to the same 14 cores that we currently get on Alder Lake-P processors, but the iGPU is going to use an all new tiled architecture which will be based on the Battlemage graphics architecture and feature up to 320 execution units or 20 Xe- Cores.

This represents a total of 2560 ALUs that could operate at clock speeds above 2 GHz given the evolution of clock speeds on TSMC’s advanced process nodes. I should also add that we’ve also seen GT3 tGPUs with 384 EUs mentioned in Intel driver leaks, so it’s entirely possible we could see even more high-end Arrow Lake-P designs than what’s mentioned. in this leaked (still old) roadmap.

Also, it’s worth pointing out that Arrow Lake-S Desktop processors will rock up to 40 cores (8 P-Core and 32 E-Core). So it looks like for mobility at least Intel would go the more efficient route as they will be using a fraction of the full base configuration that the desktop chips will get. Also, there will be a four-chip design for Arrow Lake, as announced by Intel. The Intel 20A Process Node itself will bring a 15% improvement in performance per watt and bring RibbonFET & PowerVia technology to the table.

For comparison, upcoming Intel Discrete GPUs based on the high-end DG2 GPU will use up to 512 EUs, so a 320 EU chip based on next-gen graphics architecture would deliver comparable performance to graphics cards. traditional office. The iGPU is said to measure around 80mm2 overall and, again, will feature a tGPU (Tiled-GPU) design.
