Intel Meteor Lake CPUs' Integrated Graphics

The launch of Intel’s Meteor Lake has showcased significant advancements, particularly in the power and efficiency of its integrated graphics. The latest Arc graphics within Intel CPUs demonstrate superior performance compared to AMD’s Radeon 780M iGPU, marking a noteworthy achievement where Intel surpasses AMD in integrated graphics for the first time.

To gauge the extent of the improvement in Intel’s Meteor Lake integrated graphics over previous generations, Phoronix undertook a comprehensive analysis. They conducted a series of iGPU benchmarks across five Intel laptop CPUs, each representing a distinct generation. All evaluations were carried out in a Linux environment, aligning with their previous iGPU testing and concurrent Meteor Lake Linux CPU assessments.

While not as extensive as their prior 370 CPU benchmark run, the GPU testing discussed here provides a comprehensive overview of Intel’s iGPU evolution from late 2018 to late 2023. The discussion includes two crucial graphics from Phoronix’s testing: one illustrating power consumption for each CPU during testing and another presenting the geometric mean average of all test results combined for each CPU. Additionally, we will delve into specific games and synthetic benchmarks used in the testing, with the complete results accessible at the original source for those seeking more detailed information.

The benchmarking results reveal notably significant strides in Intel’s latest generation, marking a substantial improvement in their integrated graphics processing unit (iGPU). This development stands out as Intel’s most remarkable iGPU advancement in quite some time, with the aggregated test outcomes, encompassing games and essential 3D benchmarks, vividly illustrating the notable performance disparity. Specifically, the Arc graphics of the Core Ultra 7 155H exhibit an impressive 33% average speed boost compared to the Core i7 1280P. In comparison to the older Core i7 8565U, the improvement is more than quintupled.

The benchmarking titles, such as Enemy Territory: Legacy, Tesseract, Unvanquished, and Warsow, along with synthetic benchmarks like 3DMark Wild Life Extreme and GravityMark, contribute to this comprehensive assessment. Additionally, results from Unigine’s Heaven, Valley, and Superposition benchmarks further enrich the overall findings.

Monitoring power consumption throughout the testing phase revealed a notable achievement for Intel’s latest generation, operating at approximately half the average power consumption of the preceding generation, even under full utilization.

These substantial gains in power efficiency open intriguing possibilities, raising the prospect of Intel iGPUs finding a place in entry-level handheld devices, akin to the prevalent use of AMD APUs in that domain. The outstanding power efficiency, with an average of 24 Watts, holds promise for a wide range of low-power devices.
