Intel Unveils Meteor Lake Architecture: Intel 4 Heralds the Disaggregated Future of Mobile CPUs

Intel Meteor Lake: Changing The Strategy, Laying the Foundation for Intel 3

The strategy for both the Intel 4 process and the first architecture built on it, Meteor Lake, looks to change the dynamic for the mobile market and the foreseeable future of Intel's client processors. With the Foveros 3D packaging, opting for a power-conscious mobile platform seemed the best way to showcase their gains in terms of power efficiency.

One of the main product assembly advantages of Foveros packaging is that Intel can chop and change tiles depending on the processor, which includes current technologies, I/O, graphics, and compute cores. This approach to 3D tiled packaging also means that it is theoretically easier to introduce new tiles with faster cores with higher IPC performance, new graphics processors, and newer I/O, such as Wi-Fi 7. With Foveros not limiting Intel to use a single, monolithic die, it allows Intel to use different manufacturing processes for each of the tiles and integrate them onto the silicon. This is prevalent with the compute tile being built on Intel 4, while the graphics tile in Meteor Lake is made using TSMC's N5 node. This flexibility is key to advancing innovation, customizability, and, of course, wafer yield.

Intel also introduced a dedicated in-silicon AI engine through the NPU within the SoC tile. Similar to AMD with their Ryzen AI technology, Intel is looking to capitalize on the AI rush within its client-focused processors, but with support for OpenVINO and also including MCDM driver-compliance, users can do some pretty cool things with AI inferencing on the chip. Although these implementations aren't akin to the types of AI inferencing done in the cloud via ChatGPT with dedicated AI hardware, it's a step in the right direction in a world that looks to be slowly taken over by AI.

Wrapping things up, while Intel is confirming that Meteor Lake is coming to mobile-first, any details beyond that are slim pickings. At this point in time, Intel hasn't revealed anything in regard to SKUs or possible configurations. Everything disclosed is based on the 'full; Meteor Lake processors, but Intel hasn't spoken about different configurations or what the lower-end segment might look like regarding tiles and implementations. From their Hot Chips disclosures, offering a tiled architecture allows them to scale upwards and down depending on the SKU. The high-end SKU, which hasn't been disclosed yet, will feature the full configuration and implementation of all the features. Otherwise, the scalable nature of Meteor Lake and disaggregation allows for different levels of compute and graphics tiles and the ability to scale the input and output (I/O) depending on the device.

Meteor Lake will also be the first mobile platform from Intel to use their new Core naming scheme for products, which drops the 'i' from the Core branding. This includes the Core 3, 5, and 7, as well as higher spec Ultra 5, 7, and 9 Ultra tiers. Pat Gelsinger, Intel's Chief Executive Officer (CEO), during his opening keynote at Intel Innovation 2023, states that Intel is launching the first Meteor Lake Ultra (high-end) SKU with AI capabilities (NPU) on December 14th.

We expect Intel to disclose more about specific SKUs and other specifications, such as clock speeds and core configurations, as we get closer to Meteor Lake's launch. Although we're expecting Ultra-focused Meteor Lake SKUs to launch on December 14th, no details on when we can expect other SKUs are set to hit retail channels. Meteor Lake is likely to launch with the top Ultra SKU or at least one that is close to the top of the stack. 

Reading the tea leaves ahead of Innovation 2023, one gets the impression that Intel was hoping to be just a bit closer to launch by now than they actually are. But all things will eventually come in due time...
