For the first time, average CPU performance across PCs and notebooks experienced a year-over-year decline. Between Q3 2022 and Q3 2023, desktop CPU performance dipped by 0.9%, while laptop performance dropped by a more significant 5.1%. This decline is attributed to a shift in market share towards lower-performing CPUs. While higher-performing models continued to improve, the overall average was dragged down by a greater proportion of budget-friendly and entry-level processors being sold. This trend is particularly evident in the laptop market, suggesting increased demand for affordable portable computing.
The website CPU Benchmark, which aggregates and analyzes processor benchmark data, reports a noteworthy shift in the year-on-year performance trajectory of central processing units (CPUs) in personal computers (PCs) and notebooks. For the first time in the history of their data collection, the average CPU performance has experienced a decline. This represents a significant departure from the historical trend of consistent performance improvements observed year after year.
Specifically, the data reveals a 1.94% decrease in average CPU performance when comparing the performance of CPUs released in the period spanning from October 2023 to September 2024 against the performance of CPUs released in the preceding period from October 2022 to September 2023. This decline, albeit seemingly modest, marks a turning point in the ongoing progression of CPU capabilities.
This downturn affects both desktop PCs and notebook computers, indicating a broader trend across the entire personal computing market. While the website doesn't delve deeply into the underlying reasons behind this performance regression, it can be inferred that various factors could be contributing to this phenomenon. Potential factors include market saturation, supply chain disruptions affecting component availability, a shift in prioritization towards power efficiency over raw performance gains, or potentially a slowdown in the pace of architectural and manufacturing process advancements. Further analysis would be required to definitively pinpoint the exact cause of this observed decline.
The implications of this performance dip remain to be seen. While a decrease of less than two percent might not be immediately noticeable to the average user in typical day-to-day tasks, it could have ramifications for more demanding applications, professional workloads, and the overall momentum of technological advancement in the computing industry. Continued monitoring of this trend will be crucial to understanding its long-term effects on the evolution of CPU performance and the broader personal computing landscape.

Hacker News users discussed the potential reasons behind the reported drop in average CPU performance. Some attributed it to the increasing market share of low-power Chromebooks and ARM-based laptops, skewing the average downwards. Others pointed to the global chip shortage and subsequent price increases, leading consumers to hold onto older hardware longer. A few commenters questioned the methodology of the benchmark, suggesting it might not accurately reflect real-world performance or usage patterns. The impact of integrated graphics performance being included in the overall CPU score was also debated, as was the possibility that manufacturers are prioritizing efficiency and battery life over raw processing power in recent designs. Finally, some users simply expressed skepticism about the significance of the drop, arguing that average performance remains more than adequate for most users.
The Hacker News post titled "The average CPU performance of PCs and notebooks fell for the first time" sparked a discussion with several insightful comments revolving around the provided cpubenchmark.net data. Several commenters questioned the methodology and data used to arrive at the conclusion of declining performance.
One of the most compelling arguments highlighted the potential bias introduced by the voluntary nature of CPU benchmark submissions. The commenter suggested that the decline could be attributed to fewer high-end CPU benchmarks being submitted rather than an actual decrease in performance. They pointed out that enthusiasts with high-end CPUs are less likely to upgrade frequently, especially during periods of economic downturn or when performance gains are incremental. Consequently, fewer submissions of these high-end CPUs would skew the average downwards. This argument was further strengthened by another user who noted the significant increase in low-power ARM-based devices. These lower-powered processors being included in the dataset would naturally lower the overall average performance, even if the performance of high-end devices remained stable or improved.
Another key observation was the influence of the global chip shortage. Commenters theorized that the shortage could have led to people holding onto older hardware for longer periods, leading to a higher proportion of older, less powerful CPUs in the dataset, thus driving down the average.
The discussion also delved into the website's methodology. Some users questioned the accuracy and reliability of user-submitted benchmarks, suggesting potential inconsistencies in testing environments and configurations could influence results. Others raised concerns about the weighting given to different CPU models and whether it accurately reflected market share or usage.
A few users expressed skepticism about the headline's claim, highlighting that year-on-year fluctuations can be misleading and that a longer-term perspective is necessary to determine actual trends in CPU performance. They suggested looking at multi-year trends rather than focusing on a single year-on-year comparison.
Finally, the discussion also touched upon the practical implications of the observed trend, with some users questioning whether the average user would actually notice the purported decrease in performance, given that CPU performance has generally exceeded the demands of typical everyday tasks for several years.
