Comparison of long-term performance between AMD and Intel processors
Comparison of long-term performance between AMD and Intel processors
I recently encountered an AMD 4800H series Dell G5 gaming laptop that was showing signs of declining performance. It could still manage basic tasks like running VSCode, PyCharm, or launching the Anaconda console. Meanwhile, in the same room, an HP Pavilion X360 with an 8th generation Intel U-series processor was operating smoothly, almost as it did on the day I bought it (according to the owner). When I asked both owners about their typical usage, they mentioned purchasing these devices around two years ago. The AMD model was mainly used for watching movies and simple web browsing, while the Intel version supported longer coding sessions such as Matlab and simulation modeling. The owner noted they hadn’t shut down the AMD laptop for days. Usually, one would expect the AMD to outperform the Intel after two years, but in this case, the Intel machine performed much better than it should have at that stage. I’m unsure about the exact factors affecting these results—no special testing conditions were provided. My goal is to emphasize the idea that reviewers often advise buying based on current value. A student shouldn’t expect a new laptop every year due to cost constraints. People need reliable devices lasting 3 to 4 years. Regarding Intel processors in the 3000, 4000, and 5000 series, I haven’t seen any recent content or video addressing this. I’d appreciate hearing others’ experiences with laptops that are over 18 months old, especially Ryzen models. As far as I understand, Intel still performs well in these scenarios. The main concern here is the AMD processors from those generations. Would it help if someone created a video or wrote an article after thorough testing? Please share your thoughts.
CPUs remain functional even as they get older. They either perform or stop working. Finding a completely dead AMD or Intel CPU that hasn’t been damaged or overclocked is uncommon. Their lifespan continues until they become outdated.
In general, the newest generations of AMD chips might last longer than Intel’s offerings because they consume less energy and produce less heat—factors that help preserve silicon quality. Still, any current CPU can outlast its practical lifespan if not upgraded soon. This data is mostly based on personal experiences and doesn’t provide reliable insights. An AMD user might run bloatware and neglect cleaning the device, while an Intel owner tends to maintain it well. These habits significantly influence performance, no matter the processor. Comparing random laptops isn’t fair either; a poorly built machine always underperforms regardless of the chip. Thermal management and power delivery also depend heavily on manufacturing quality, which impacts how well the hardware functions over time.
That is a valid point. But what I'm hoping is someone could do a video or write an article with a full detailed analysis. All that happens in these forums is debate and arguments may be.
I own an older laptop running an i7-4820hq and a more recent model with a Ryzen 7 3700U. Over the past six years, I've never faced any issues with the Intel machine, but the Ryzen one (just two years old) recently encountered some problems that I thought were resolved, only to have them return. I repeat that several times. Because these problems are sporadic, I'm unsure if I fixed them or not—sometimes it boots fine for weeks, then it fails completely the next day. It's possible the Ryzen laptop was a more affordable option, but performance-wise, neither machine has shown any drawbacks so far.
The challenge lies in the difficulty of conducting tests. You'd need identical laptops from the same brand and model—just swapping one with an Intel counterpart. Then simulate regular use over several years, finally running the same tests to detect any real performance shifts. It would require a massive effort, and honestly, most people don’t see enough value in it. Since the outcome is clear, there’s little incentive to invest time or resources. With identical habits, neither Intel nor AMD offers any lasting advantage.
The 4800h will completely outperform the 4-core U processor. The slight slowdown is likely because of overheating and it reducing performance below its normal speed. Probably caused by dust in the cooling system or poor thermal paste combined with outdated software and failing storage.
