To make it easier to understand, I am bringing laptops into the discussion. AMD Strix Point 28W CPU matches the performance of 50W CPU of previous gen. How does it help?There is no way in this world that anyone (who is not running some kind of mining or similar operation) is saving 400-500 Rs per month by changing just the CPU. These efficiency calculations are for max load. Most times, the CPUs are running close to or under 25W. So, the savings would be less than Rs. 100 per month even for always on computers.
It is not just direct power savings. Even a 10% increase in performance, with a 30% decrease in power draw brings huge improvement. Take corporate laptops for example. Our laptops are used 9-10 hours a day. We do local code compilation which relies heavily on CPU. My current office laptop is powered by a 12th gen Intel CPU and the battery life sucks donkey balls. If I unplug, I barely get 3-4 hours of battery life. As a result, we all work with laptopsconnected to power most of the time. This laptop is just 1.5 years old and battery degraded to 81%. I now get max of 3 hours of battery life. Reason is highly inefficient chip. By the time the laptop is 2 years old, i will ahve to change the battery and I have no idea how much it costs. At the same time, the performance is average at best. Most of the time CPU is running at 60-80% load. When I initiate a code compilation, it gets hot. When I set it to sleep, the idle battery drain is higher and so I end up keeping it plugged entire night. I do not want to wake up with laptops whose battery is totally drained. Now, imagine how much money we are losing by relying on a CPU that is not power efficient!
Coming to desktops where there is no battery to think of, the savings are not immediately noticed. We use desktops for heavy lifting. Be it gaming or running multiple VMs or containers etc. If I have a CPU that draws less power and performs better, I end up with simulations or rendering or VMs running while the desktop is drawing less power. As drivers get better, the peformance goes up. I am finishing my heavy compilations or rendering faster in cases where max CPU utilized because in these cases, the CPU does not throttle any more as it is not reaching thermal limits. As the job gets done faster, I am saving on power utilization, on component life.
Now, combine these two (desktop + laptop) and you will understand why its not less than 100/- per month.
I have not even touched on servers. Imagine the amount of savings for corporates when a highly efficient CPU line up comes into the company.
A simple example is that ever since I got my MBP powered by M2 Pro, I am doing more work on that one because it consumes so little power and does majority fo the work. This is where AMD is going now, this is where Qualcomm comes into picture. Intel ****ed up PPW in last few years and AMD is bringing this back to front.
