MacBook Air M1 Apple Silicon Sleep High Power Consumption?

21. July 2022 Robert Lohr3 Comments

When I first got the MacBook and put it to sleep on battery, as one does, I wondered why the energy store had lost a surprisingly high amount of charge after just a couple of days of sitting on a shelf untouched, lid closed. Now that I have a power meter (almost a year later), I was curious and hooked up the plugged-in computer to it. As you can see from the title image, the result was 2.3 frigging watts. But why?

Given this number, I wanted to open this blog post with the following statements.

Here is an interesting fact for you. The most power-efficient computer of the past decade allows itself over 2W of power while it sleeps. Yes, two frigging watts. Sleeping.

Being a curious nut, I did some more digging and then overhauled this blog post accordingly. But first, let me continue with my original vision of this little rant.

This is time travel, my friends.

OpenRGB – An RGB Software I Want to Use (It Runs on Linux!)

30. January 20217. February 2021 Robert LohrLeave a comment

If you are in the market for anything gaming PC or gaming laptop related, chances are, you have come across the industry-wide trend of RGB illuminated hardware and peripherals. Everything is RGB, from the graphics card to the RAM, to your headset (because you can see the lights when you wear it 🙄), and many, many more. I am not against RGB lighting per se, but if you follow the industry as a PC hardware enthusiast, it is evident that in some aspects, this has gone too far.

Quick side note: after a rant about RGB software, I will show examples of using OpenRGB on Windows and Linux. If you are interested in only that, skip the rant and scroll to the bottom.

Road to the Perfect Mini ITX PC (Part 5): Other Small Form-Factor ITX Cases

11. December 202012. December 2020 Robert LohrLeave a comment

Previously on “Road to the Perfect Mini ITX PC”:

The first two cases I had bought were before I became aware of all the mass-market and niche options that existed at that time. Not only have I learned about the DAN Case, NCase M1, and Streacom DA2, but companies have released more cases during the past year. I’m talking about the NZXT H1, the Cooler Master NR200, or, recently, Phanteks’ second attempt at the Evolv Shift. Even Lian Li’s TU150 landed during that time, my current case. There are even so many more cases, like the Louqe Ghost S1, the FormD T1, Sliger SM560, and many more.

Road to the Perfect Mini ITX PC (Part 4): Lian Li TU150

28. November 202010. November 2020 Robert Lohr1 Comment

In a few aspects, the Lian Li TU150 is comparable to the NZXT H200. One: for an ITX enclosure, it is on the bigger side. And two: it has a similarly closed-off front. Other than that, they are pretty different, though. In some areas, that is a good thing, and it is a bad thing in others.

In the timeframe of just over a year, this is the fourth (!) computer case that I have tried. Usually, it is the CPU or GPU that gets replaced more often 😅 It is also my current case, which means I can provide good pictures to visualize my thought process better.

Road to the Perfect Mini ITX PC (Part 3): Fractal Design Meshify C White

21. November 202010. November 2020 Robert Lohr1 Comment

In the third part of my road to the perfect mini ITX computer case, things will get a bit weird. As you may have gathered from the title, I will not talk about a mini ITX enclosure in this blog post. Quite the opposite, in fact: the Fractal Design Meshify C is a full-sized mid-tower ATX case.

You may now wonder why I suddenly had a change of heart and ditched a big.SMALL™ case for a not-so-small big computer tower. Well, I was surrendering to big graphics cards. Or, put the other way around, I was annoyed that I had to search endlessly to find a fast and quiet, and affordable two-slot graphics card model, only to fail ultimately. But, let me not get ahead of myself and start from the beginning, the same way I did for the previous two blog posts.

Road to the Perfect Mini ITX PC (Part 2): NZXT H200

14. November 202010. November 2020 Robert Lohr1 Comment

The second of the bunch is one of the stylish cases from NZXT, the H200. While it is technically a mini ITX chassis, it is a large case for that market segment. Just like the Fractal Design Core 500, it is compatible with a wide range of hardware, making it the perfect enclosure for price-conscious buyers. On top of that, it also is beautiful.

Unfortunately, I do not have an image of a complete desk setup with this case. Here is one with a good look at the internal layout and installed hardware.

Road to the Perfect Mini ITX PC (Part 1): Fractal Design Core 500

10. November 2020 Robert Lohr1 Comment

The computer that I bought roughly a year ago has seen quite a few revisions already. But I am not talking about the core hardware – although I switched the GPU at one point. I mean the case. I wanted to go with something small from the start, so the basis is a mini ITX mainboard. However, I have not been incredibly happy with any of the cases so far. In this first installment in a series of several blog posts, one for each computer case, I will share my experiences in building a small, attractive, and performant and yet price efficient computer. I will cover design, hardware compatibility, pricing, and availability. Unlike the YouTube tech creators, not everybody has a seemingly unlimited budget or receives hardware from the manufacturers for review or showcases. It may look easy in all those YouTube videos, but it might not be for everyone.

Although I am mainly talking about gaming hardware, the same thoughts also apply to compact office PCs or workstations. Depending on the use case, i.e., which PC component requires the most focus, one or the other might become less or more relevant. So, first off is the Fractal Design Core 500.

How Corona Virus and Lockdown Affect Me

28. June 2020 Robert Lohr1 Comment

I guess everybody has a story about how the current situation affects them. Since I share a few of my thoughts on the Internet and this one also has to do with technology, usually the main topic of my musings, I think this is something worth addressing.

I do not know if it makes any difference, but I will say it anyway for the sake of context. I live in Germany and of all the countries in the world we are in fairly good shape so far. We have had lockdown procedures for a while, but nothing so restricting that forbade leaving the house for anything other than going to work, the doctor or buy groceries. We could go for walks or outdoor sports if we were not meeting with other people. It was social distancing, but not hiding at home.

I work as a software developer at an IT company and my employer, like many others, relaxed the usual home office regulations month after month and basically the whole company started to work from their homes, me included. There are a few that do not like it and rather go to the office – which is safe, I presume, as there is basically no one there. I, on the other hand, prefer working from home and this is where the story of this blog post starts.

The Linux Experiment: One Month Later

12. April 2020 Robert Lohr2 Comments

It has been roughly a month since I switched from using Windows 10 as my main operating system to Linux. The reasons for that have all been detailed in The Switching Windows to Linux Experiment blog post. Now I will share a few of the experiences I have made during the first month (it’s been that long already) and what I think about how well it is going.

Let me address the elefant in the room first, the distribution. I think that is likely the first question you, the reader, would ask. The short answer is Pop!_OS by System76.

The Switching Windows to Linux Experiment

22. March 202022. March 2020 Robert Lohr2 Comments

(Beware of the many text)

For the longest time I have been a Windows user. My first computer came with Windows 98 SE (ignoring the Amiga before it) and I’ve used Windows as the main operating system for almost all that time since then. There was a brief excursion into the Apple world for about a year or two, but apart from that: Microsoft’s creation. It’s not that I have not tried using Linux, it’s just that for many years my needs could not be easily satisfied by a Linux based operating system. For one, I have always enjoyed PC gaming and I still do. I’ve tried going with a console, but that was one of the worst decisions I had made in 2019. There also was a long period where I had used my computer as a TV, a time where Youtube and all the other streaming services hadn’t existed. And although I had managed to get the TV tuners to somehow work, it was not comparable to the experience on Windows. For my use case, over all those years, Microsoft’s OS simply was the Vulkan choice. But now in 2020, this isn’t the case anymore. Things have changed, including the maturity of Linux as well as my own needs and my views. Therefore, it’s about time that I revisit this topic.

Benchmark RX 570 vs. RX 5700 XT vs. GTX 1660 Super, Ryzen 2600 OC, 3600MHz RAM

14. February 2020 Robert LohrLeave a comment

At the end of last year, I was researching GPUs like a madman, trying to find the best option for price and performance and maybe also have some headroom for a future CPU upgrade. My starting point was a Ryzen 5 2600, 16 GB of 3000 MHz CL15 RAM and an AMD RX 570 with 8 GB of VRAM. A very good performance per buck machine in the summer of 2019 for 1080p gaming. It was purpose-built to be cheap with an upgrade path in the near future. However, my inner hardware enthusiast didn’t want to be content. It also didn’t help that the two games I was playing at that time performed rather poorly (which was the games fault, but you take every excuse you can get to buy new stuff).

Putting that aside, I have data of three graphics cards to compare, tested in four games at three different in-game settings – plus a custom one for two games that I used for playing. In addition to that, I have a bit of CPU overclocking as a result of troubleshooting and a RAM upgrade from a 3000 MHz CL15 kit to a 3600 MHz CL17 kit – which is running at 3400 MHz. More wasn’t possible with this motherboard and CPU. This post isn’t about the CPU overclocking though. I did that to see if the 5700 XT was limited by the R5 2600 and would perform better with a faster CPU. Well no surprise there, but as it turned out, the numbers I found were not caused by the CPU. More on that later.

AMD Radeon RX 5700 XT Stuttering at 1080p

30. December 20193. February 2020 Robert LohrLeave a comment

Quick note before I go into any details: I did not find a solution for this problem, unfortunately. I’ll be explaining what happened and show frame time graphs as proof.

So, with that out of the way, let’s get into it. I’m certainly not the only one with this issue. If you employ the search engine of your liking you will find many threads covering that topic (like here and here and here and here and so on). Some managed to get it working, some did not. I’m obviously in the latter category.

What happens? From what I found in my research it seems like the RX 5700 XT GPU aggressively tries to save energy if it is not fully utilized. If you run MSI’s Afterburner or any other monitoring software, then you’ll see the GPU load and frequency being all over the place. In general, this is a good thing – if it does not affect perceived performance. And this is where it fell apart for me.

Windows Fluent Design – Rendering Bugs?

16. July 2018 Robert LohrLeave a comment

As an avid listener of Windows Weekly I often hear discussions between Paul Thurrott, Mary Joe Foley and Leo Laporte about Microsoft’s Fluent Design. Microsoft continues to evolve the visual language of Windows and thus it’s a regular topic on one of my favorite podcasts. I’ve been noticing it here and there myself, mainly in system dialogs, but I’ve never really paid any attention because none of the applications I use on a regular basis make use of it – and currently I’m rather happy about that fact. Just recently though, I was struck by one effect in particular and that was the spark that got this blog post going. To be honest, in most cases where I notice these Fluent Design elements I think of them as rendering bugs. Like sometimes in games, when the graphics driver is not yet optimized, or a badly programmed game engine draws odd pictures sometimes, flaws in an otherwise normal picture. I have a few examples to show to you.

I could really bite myself in the butt right now

Somehow, I managed to lose the Intel mounting bracket and standoffs for my Corsair H100i v2 liquid cooler. To be honest, I’m pretty sure I sold them together with the Intel motherboard when I switched to AMD Ryzen. Yes, you read that correctly.

Sold. With. Motherboard.

I can’t find that stuff anywhere in all the packaging that I always keep around until I throw away or sell the hardware. So that’s the only logical conclusion says Mr. Spock.Read More »
