If we're going to bring up the environment, the computers made more than ten years ago are vastly more energy inefficient and pull more energy than most computers you can buy in the last five years. Recycling those computers and harvesting their base materials to produce better computers would be good for the environment because it reduces the carbon footprint of that person using a computer.
Maybe the systems which are obsoleted do not run 24/7 but only a few hours a week. Then the energy saved by a new system will never compensate the energy consumed for manufacturing the new system.
There are plenty of decommisioned newer systems.
Raising the baseline to x86_64-v2 also has the effect of raising the generational baseline to something that is generally useful for contemporary Linux system software.
Actually it means obsoleting systems for the sake of ... obsoleting systems (because some day in the future they could be insufficient to run a then current Linux).
In german c't magazine 2011 issue 12 there was a suggestion for a high performance PC with a Phenom II X6. Probably this system still outperforms everything built ever since with something called Celeron inside. And it will be obsoleted by requiring x86_64-v2.
Yeah, actually a great example: The article had two systems, one AMD (Phenom II) and one Intel (i5-2500). The Intel one already is x86_64-v2. The AMD sytem has an idle power consumption of 53W, while the Intel system uses only (cough) 27W. In multicore benchmarks, the AMD is slightly faster, the Intel wins in singlecore benchmarks by a significant margin. An Intel i3-4350 is twice as fast in single/dual-core load, and about the same speed in 6+ core loads. A Pentium G5500 is (significantly) faster in all benchmarks. The "high end" system is beaten by the low end from 4 years ago. Current entry level systems use 8-20 Watt in idle (some even less). Thats a difference of at least 30 Watts, significantly more under load. The old system will spend more time in high load than a current one. Regards, Stefan
