As far as I’m concerned, the performance difference between AMD and Intel simply isn’t enough to worry about when we are comparing U-series processors for laptops.
Comparing Intel’s best mobile processor (Core i7-1185G7) to AMD’s best mobile processor (Ryzen 9 4900U).1,2, it is basically a toss-up which is better. Intel wins in terms of graphics, single-core performance (because of higher single-core clock speed), and AI. AMD wins in terms of energy efficiency (i.e., battery life) and multi-core performance (because it has 8 cores whereas the i7-1185G7 only has 4 cores).
Most people don’t run software that can use 8 cores, so the i7-1185G7 will probably give them better performance. For some people, battery life is extremely important, so Ryzen 9 4900U will be better. Even for people who care about multi-core performance, such as people doing video rendering, the choice is not clear. The i7-1185G7 has a better GPU (Intel Xe Graphics G7), which helps when doing video editing and most video rendering software can use the GPGPU functions. The i7-1185G7 supports up to 64GB RAM, whereas the Ryzen 9 4900U only supports up to 32GB RAM, which may be a factor when doing video rendering.
Intel is better than AMD in terms of its support for FOSS. Intel has contributed 7.65% of the code in the Linux kernel, whereas AMD has contributed 1.90%. Intel develops the graphics driver for its CPUs in mainline Linux, whereas AMD contributes to the FOSS driver for Radeon GPUs, but mainly releases info and lets the community develop it. Maybe this difference is simply because Intel was a much richer company and could afford to spend more money on supporting Linux.
On the other hand, Intel has a long history of monopolistic practices, which people may not want to support. In 2009, the EU fined Intel $1.45 billion for violating European anti-trust laws.
Some people may also want to boycott Intel, because it has invested $35 billion in Israel, and has operated fabs at Kiryat Gat since 1999. Intel currently plans to invest $5 billion in upgrading its Kiryat Gat fab and is considering investing even more in the future.
Al-Awda, the Palestinian Right to Return Coalition, has called on Intel to close its plants in Kiryat Gat, which was the site of the former Palestinian villages Iraq al-Manshiya and Faluja, that were ethnically cleansed by the Israelis in 1948-49.
At this point, I’m not sure that Intel still has a monopoly position that it can abuse. However, I do find the BDS argument against Intel to be compelling.
