Over 50% Performance Per Watt Gain Over 13th Gen Raptor Lake Is Reportedly the Goal for Intel 14th Gen Meteor Lake CPUs


The launch of Intel’s 14th Gen Meteor Lake CPUs is anticipated for later this year, with the mobility platform as its initial market. The chips will be the first to use a hybrid x86 core architecture with chiplet technology.

According to information provided by the very reliable leaker and insider OneRaichu, the 14th generation Intel Meteor Lake CPUs aim to achieve significant performance and efficiency improvements. The P-Cores and E-Cores of Intel’s 14th-Gen Meteor Lake CPUs will have a brand-new core architecture, and while the hybrid implementation will still be there, the CPU itself will utilise a number of additional IPs that will be connected via numerous chiplets.

Although a desktop lineup was initially anticipated, it is reported that the Intel 14th Gen Meteor Lake CPUs will focus first on mobility. But getting back to the specifics, it is said that the Meteor Lake CPUs aim to achieve a performance per watt (efficiency) gain of over 50% over the previous generation. This is unquestionably a significant improvement in efficiency as AMD’s Zen 4 architecture, introduced last year, saw a >25% boost in performance per watt. Raptor Lake’s performance per watt (Raptor Cove + Gracemont) is compared to Meteor Lake’s and is used when a similar core CPU is employed.

But that’s not all; the leaker also notes that the new tGPU or Tiled-GPU architecture, which will include new Xe GPU cores, may allow Intel’s Meteor Lake CPUs to enhance GPU performance by a factor of two. According to the exact configuration, there are 128 Execution units operating at clock rates greater than 2.0 GHz.

The Meteor Lake CPUs will, as Raja Koduri mentions, use a tiled Arc graphics-powered GPU, making them a completely new kind of graphics on a chip. It is now referred to as tGPU (Tiled GPU / Next-Gen Graphics Engine) and is neither an iGPU nor a dGPU. The brand-new Xe-HPG graphics architecture, made available by the Meteor Lake CPUs, will provide higher performance at the same level of power efficiency as current integrated GPUs. Additionally, this will enable improved support for XeSS and DirectX 12 Ultimate, capabilities that are now only supported by the Alchemist lineup.

With a 2x performance increase and all those tasty features, AMD’s RDNA 3 GPUs in the same integrated market may face some fierce competition. The integrated GPU market, which is constantly changing and seeing significant generational improvements from both AMD and Intel, may also put additional pressure on NVIDIA.

The 14th Gen Meteor Lake CPUs, according to Intel, will have a brand-new tiled architecture, which essentially means that the company has chosen to go chiplet-only. The Meteor Lake CPUs have 4 primary tiles. The IO Tile, SOC Tile, GFX Tile, and Compute Tile are all available. The CPU Tile and GFX Tile are parts of the compute tile. The CPU Tile will feature a novel hybrid core architecture that combines Crestmont E-Cores with Redwood Cove P-Cores to enable improved performance throughput at a reduced power consumption.

Expect further information later this year as Intel stated during its most recent earnings call that the company will increase Meteor Lake CPU production in 2H 2023.
