Best Low Power (TDP) CPU for Home Server [2022]
A home server doesn’t need to be as powerful as a commercial server. Building your own home server is overall cheaper and requires some basic knowledge of assembling PC parts. When hunting for hardware to build a home server from scratch, you really don’t need to do a lot of research. There’s no need to buy a high-end graphics card or CPU for a home server. A low TDP CPU or APU can deal with all the processing jobs alone in this case.
The role of a home server is to receive requests and send data back to the remote computer. So, it doesn’t make any sense to invest in power-hungry parts. But a home server can put a load on your electricity bill as it remains turned on for a longer time.
One way around this is to include energy-efficient hardware in a home server computer. In-home server computers, there’s almost no use of a dedicated graphics card. So, the only component left is the processor, that’s more likely to suck more watts.
So, it’s better to invest in a low TDP processor if you are building a home server to back up your storage, serving as a web host or streaming content.
Generally, a machine with at least a 300MHz processor and 64MB RAM shows up as a decent server. But we now have applications that demand more power out of a CPU. So if you go with a multi-core low TDP CPU with a higher clock speed, then you’ll have a fast home server sitting next to you.
This guide reviews some of the best low-TDP processors for home server computers. Some of these also have a built-in graphics card and show up as a great deal for a Plex or NAS home server.

3DNews Technologies and IT market. Notebooks & Netbooks AMD Zen Dual-Core 6W Processors Powered by… The most interesting in the reviews
08/04/2020 [19:54], Konstantin Khodakovsky AMD uses the names Athlon Gold and Silver for affordable processor solutions that feature low power consumption and fewer cores. These chips are still based on the Zen or Zen+ architecture combined with simple graphics. Now there are two even simpler 6-watt chips aimed at cheap laptops used in education.
These new processors dispense with the Athlon branding and are simply called AMD 3015e and 3020e — they use the same «e» suffix that was last seen in the company’s processor family in 2011. Lenovo is going to use the new AMD 3015e in two new second generation 100e and 300e educational laptops based on Windows 10. Interestingly, in 2018, previous generation Lenovo devices had both Windows and Chrome OS versions.
The Lenovo 100e laptop will offer Wi-Fi 6, 64GB eMMC storage, 4GB DDR4, and an 11.6-inch 1366×768 display with 250 nits of brightness. In turn, Lenovo 300e 2nd Gen has similar characteristics (there is, however, a model with 128 GB of storage), but it is equipped with a hinge that allows you to flip the touch screen to the opposite side. The device also supports the optional AES Pen. With dimensions of 290 × 204 × 20.85 mm, the device weighs 1.32 kg. The battery with a capacity of 42 Wh is designed for approximately 12 hours of operation. It will go on sale in September for a price of $299. Both devices have many software features focused on students and safety. Sources:

It indicates ultra-low power consumption: these processors have a TDP of 6 W, include two CPU cores and integrated Vega 3 graphics. It is the smallest APU of all AMD Zen-based offerings and is already on the market under the AMD Athlon Mobile brand. So, what are these processors? The AMD 3015e is multi-threaded and runs at up to 2.3 GHz, but features a low graphics clock of 600 MHz and only DDR4 1600 MHz memory. In turn, the AMD 3020e has a frequency of up to 2.6 GHz, it has graphics running at 1000 MHz, and there is also support for DDR4-2400 memory, but there is no multithreading. Obviously, we are talking about compromises to comply with the 6 W TDP. 
Users will also get a shock and scratch resistant case design, about 14 hours of battery life and support for fast charging, which replenishes the battery by 42 Wh up to 80% in an hour. With sizes 290 × 204 × 19.9 mm, it weighs 1.22 kg. The keyboard is water resistant. The computer will go on sale in September at a price of $219.
