Intel’s Core Ultra Meteor Lake: A Refresh-Like Performer That Defies Expectations

Intel’s Core Ultra Meteor Lake processors are generating a lot of buzz in the tech world. This new generation of chips represents a significant upgrade for Intel’s client portfolio, boasting upgraded core architectures and a 4nm-class process node. It is also the first chiplet-based design from Intel. However, there is some controversy surrounding these processors, as they appear to be largely identical to the previous generation’s Raptor Lake family.

According to Tim Wilson, the VP of Intel’s Engineering Group and GM of SoC design, the Meteor Lake cores share many similarities with the Raptor Lake cores. The Redwood Cove and Crestmont cores in the Meteor Lake processors are architecturally similar to the Raptor Cove and Gracemont cores in the Raptor Lake processors. While there have been some minor changes, most of the last-gen design has been retained.

The Redwood Cove core in the Meteor Lake processors is almost identical to the Golden Cove core in the Raptor Lake processors. It features the same decoders, allocation Q, and op-cache, along with an identical memory subsystem. The only notable addition is a new AMX unit for matrix workloads, although it may be reserved for data center products rather than the client platform.

The Crestmont core in the Meteor Lake processors has a slightly wider Allocate/Rename Buffer and some tweaks to the Vector Execution Units compared to its Raptor Lake counterpart. Overall, the differences between the two generations are minimal.

Despite being marketed as a major upgrade, the Meteor Lake processors face criticism for their power efficiency. In most scenarios, they fall behind AMD’s year-old Ryzen 7000 “Phoenix” chips in both performance and efficiency. Intel has released a firmware update to improve performance and efficiency, but it remains to be seen how many updates will be necessary for Meteor Lake to become competitive.

When asked about the differences between the P-core and E-Cores of Meteor Lake compared to Raptor Lake, Tim Wilson explained that while there are some improvements in the microarchitecture of both the P and E cores, the core architecture remains very similar to Raptor Lake. This is because Intel focused on achieving a stable process flow with the new Intel 4 process, rather than making significant architectural changes.

Regarding the technical differences between traditional E-cores and low-power E-cores, Wilson clarified that they have the same architecture but are optimized differently for different tasks. The E-cores in the compute block are optimized for higher performance and multithreaded tasks, while the LPE cores in the SoC block are optimized for low-power tasks that don’t require the full computing power of the P/E cores.

One interesting aspect of the Meteor Lake processors is the use of TSMC N6 technology for the I/O module. This choice was driven by technical considerations rather than cost issues. The TSMC N6 process allows for high-voltage type transistors and has proven effective and cost-efficient for various types of chips.

In terms of the manufacturing process, the I/O module is built on Intel’s 1227 node, which serves as a base through miniature connectors. This passive exchanger provides “wires” between the blocks placed on it.

Overall, Intel’s Core Ultra Meteor Lake processors offer some improvements over their predecessors but also face criticism for their power efficiency. While they may not be the upgrade initially anticipated, they still represent a step forward for Intel’s client portfolio. As with any new technology, firmware updates and optimizations may help address some of the initial concerns and make Meteor Lake more competitive in the market.
