Indeed C states are a different beast altogether, but right now I wanted to focus on raw full power since that is the simplest measurement. That is very much true, the only saving grace of buying used Xeons is delaying them from going to e-waste. And yeah, not much more to say for Zen 3 other than OMG this is incredible stuff. And just as I found out now, they seem to be getting kind of cheap. Again, it seems like if your use case uses a lot of power and power is expensive, you shouldn't immediately disregard Intel, but AMD ZEN 3 seems like a very very good option.

I was just a minute away of posting about this But this seems to be very much a thing, Intel was lazy and let AMD catch up and run them over. A 5700X is about 210€, while the E5-2667 v4 can be had for about 40€. Motherboards are a different story though, new Chinese X99 boards are about 100€, the cheap ones at least, although they do go down to 75€. AM4 B450 boards go for about the same price range, so the CPU is the limiting factor. At 140W, 6 hours a day, 0.40 cents per kWh the bill would be 123€. If we say the 5700X hypothetically has a 2x lower power consumption for the same amount of work, that would amount to about 61.5€. Meaning you would save 61.5€ every year by going AMD. This is hypothetical of course, I don't believe you could ever achieve that... But it might be worth it in the long run if the electricity is expensive like that, if not... not much reason to go newer just for efficiency.

Exactly, probably what I was trying to find is if the stagnation of progress extended to energy efficiency too. Which it probably did. This means that if you can get the old Broadwell Xeon platforms for cheap, you might still be very well off for a few years at least. However, that only considers Intel. Let's try to look at some AMD CPUs in this sense. (Only the consumer and prosumer ones since AMD doesn't make smaller than EPYC server CPUs) AMD has disrupted that stagnation and according to Passmark at least: https://www.cpubenchmark.net/compare/2830vs4492vs4814vs4576vs3485/Intel-Xeon-E5-2667-v4-vs-Intel-Xeon-Gold-5315Y-vs-AMD-Ryzen-7-5700X-vs-Intel-Xeon-E-2388G-vs-AMD-Ryzen-7-3700X If the 3700X has a power draw of 140W: https://www.techpowerup.com/review/amd-ryzen-7-3700x/18.html it's points per watt goes about 162 And the 5700X a power draw of 126W: https://www.techpowerup.com/review/amd-ryzen-7-5700x/18.html for points per watt of 212 Now we got to the MASSIVE difference I was trying to find. Over 2x the efficiency just like that, even though the processor is from 2022. This means that if you're willing to go AMD, the ZEN3 architecture packs an incredible punch for efficiency and if you enable ECO mode it only gets better. Might actually be worth spending more for this if power draw is a concern, although you have to remember it is only one part (a big one though) of a PC and other parts may have a larger power draw than you think.

Great! Let's figure out this server thing. I compared these 2 processors: https://www.cpubenchmark.net/compare/2830vs4492/Intel-Xeon-E5-2667-v4-vs-Intel-Xeon-Gold-5315Y E5-2667 v4 and Xeon Gold 5315Y. Both very similar TDPs, 135W and 140W and similar base clocks and turbo clocks although the Gold can have a higher clock due to Intel Speedstep but is probably not used for the benchmark. I could not find Cinebench results for the 5315Y so Passmark it is. 148 points per Watt for the 5315Y 103 points per Watt for the E5-2667 v4 Almost 44% higher efficiency! This is what 5 years of innovation gets you. Not 5x, but its a lot. Also that only applies if their TDPs actually are their power draw, which it might not be. But finally it is something I can work with. What do you think? Anything I've missed here?

That is a good point, however we can use that exact knowledge to our advantage when we see that for gaming these chips are actually very much perfect. Maybe getting 14nm chips is "good enough" for the most part. Or maybe it makes sense to go higher a generation or 2, Skylake is still very popular. Well yes, I was just saying I was expecting more from 7 years of innovation.

Alright, Ukraine strikes again looks like a very nice comparison has already been made: And the efficiency difference compared to an i3 12100 is very similar to what I was expecting for the Cinebench results, however the gaming results stumped me. There is not much difference there... and it intrigues me. More research?

Right, but the X5670 has a TDP of 95W so it's not exactly an incredible jump in efficiency, what's that, 50%? I would be hoping for more. Indeed it is! However that is if the score was achieved at 125W, which it was most likely not, closer to 190W according to TechPowerUp, which immediately brings this to 4x. This is still a gigantic difference though and shows that anything older than Haswell is probably not a good idea if power consumption is a problem for you. The E5-2667 v4 though is another story, at 135W TDP (which hopefully is it's actual power draw) has a CBR15 score of 1448 and the 13600K of 3652 while the 4770k gets 709 for slightly less power consumption making the 13600K little more than twice as efficient as the 2667 v4 (somebody should do a CBR23 test on that thing to be sure) and 4x as efficient as the 4770K. So, maybe the magic point actually wasn't Haswell, but Broadwell. And anything older than Broadwell is too inefficient to feasibly buy, especially if you also need to buy RAM for it. That seems to be a good idea since power draw and Cinebench figures seem to be on all CPUs at some point. Thanks! Also, I know that AMD's CPUs seem to have a much better efficiency than Intel right now, at least in multithreaded workloads because according to TechPowerUp, their single-threaded efficiency can sometimes be 2 times lower. Or maybe it has something to do with sleep states?

I spent quite a long time trying to find a comprehensive test of CPU power consumption compared to their computational power, meaning energy efficiency. Techpowerup does efficiency measurements in their more recent CPU reviews, however generations older than the 7th Intel Core generation or 1st AMD Ryzen generation. How do Haswell processors compare? How does Sandy-Bridge compare? Broadwell? Skylake? AMD Bulldozer? All of them had significant jumps in Lithography shrinking, while the newer ones... well you know how long Intel has been using 14 nm. Craft computing has recently uploaded a video about old Xeon processors, E5 2667 v4 Broadwell to be exact which showed their gaming performance mostly on par with a Ryzen 7 3700X, but failed to measure their power consumption. This is still great information to see that you don't have to spend obscene amounts of money just to run Borderlands 3 or The Witcher 3 on FullHD. Now I know everything is processor to processor and stuff, but I also know that big jumps in efficiency these days are very useful to know about in the current energy crisis (even though its kinda under control right now) and the ever-hotter summer months which combined with the energy crisis is not good for your A/C bill (assuming you even have one). Is there any source you know of that could provide such information? I know that cpubenchmark.net has one, but their power consumption values come straight from TDP which as we all know is nearly useless these days, although if you think it might be of use let me know. Thank you for any and all insight you might have!

It's an old AMD build with an FX-6300 and ASUS M5A97 R2.0 motherboard. When I slid it out from my desk to plug in a USB hub, it just crashed. I took it out, unplugged everything except the power and GPU output, in the BIOS everything was fine, until I put it upright again. Same thing happens when I smack it, hold it in the air about 3cm and let it fall, also when I physically pull the CPU cooler. I first suspected the PSU, but using another one yielded the same result. I tried reseating the CPU and fitting the stock cooler instead, no change, but when I tried without any cooler it did work even with me repeatedly smacking it sort of violently (until thermal protection cut it). This needs further investigation. I need any and all ideas you might have, this isn't strictly an emergency situation, since it continues to work when laying down, but I would like to figure out what the problem is and fix it. I also have other computers to use, but this is the fastest one. I need to figure out whether it's the CPU or motherboard, which I have neither a spare of right now. I am suspecting the mobo, but not sure yet. Thank you everyone!

My Excel sheet did not save despite me manually saving it regularly as I filled it. I closed Excel, opened it back up to check whether everything was OK and none of my changes saved. There's nothing on the automatic recovery and nothing in the "Unsaved sheets" button. Any ideas?

I have an Acer Aspire 1 A111-31 series, model number N16Q6. I managed to spill a little bit of beer on the keyboard thus roughly the center part of it wasn't working, the rest of it was fine though. I took it apart to clean it with some distilled water and isopropyl alcohol and found that nothing got on the motherboard, just the keyboard. There is sort of a cover from the metal sheet that seems to have prevented it from getting to it. It was working before I disassembled it, just the keyboard was a problem, now I reassembled after cleaning and drying for around 3 days (the top case part where the keyboard and touchpad is) I plugged it in, the charging light came on and I pushed the power button. It started up, started the boot to windows and then went dead right away. No charging light, no power button reaction, nothing. I do have to point out that there is no fan to spin. I tried reseating the connectors multiple times and cleaning them too. I tried disconnecting the battery and unplugging it from the adapter and leaving it like that overnight. No help. I also tried removing the CMOS battery while everything was unplugged to see if that would change something. It didn't. Now I am actually quite puzzled about what could possibly have happened. The power button and the indicator lights are a part of the top case connected through a single ribbon cable so maybe there is a problem in there, although I am not sure why it would turn off right after. I think I should've just lived with it and got a USB keyboard but I guess I can't do that now. Anything you can think of? I am out of ideas. Thank you!

FSP Hexa is tier 7? What are you talking about? I have the 500W version in my gaming PC, never had any problems, overclocking was a breeze, it is quiet enough, efficiency good enough, WHAT ELSE DO YOU WANT? It's been there for 5 years, used almost daily for a long time! It doesn't overheat, it doesn't crackle, it doesn't spike voltages, NOTHING! But I do have a question here. What about Eurocase power supplies? They're pretty common in cheap PCs, where would you rate them?

Seems like the best solution really, thank you! Good point, so far the best Price/GB ratio seems to be on 4TB drives with 3TB being very close to em. Yeah, used ones are a bit of a gamble. This isn't really a mission critical computer and the drives would be in RAID 5, so if one goes, I have time to react. More or less... I won't if another one goes. Since you provide your location as Kentucky, I think you might be a bit far from Slovakia... thanks for the offer though! Dayum. That's a bargain, but I've never heard of Alternate in Slovakia... will check it though. Do you think these drives could be suitable for RAID? I know that WD Green and Seagate equivalent are not recommended to be used in RAID because of a lack of one function. Cant remember the name, but something about error checking. Also, why is it that those drives are so much cheaper inside of the enclosure? Those are High-end drives too! Yeah, only if I could buy it from there... and you searched that just to answer my question thank you! Slovakia is far away from pretty much everything and I live in Eastern Slovakia, where there's even less than nothing around. But I managed somehow to this day, I sure will manage this time!

I have a NAS server set up with the drives it came in (2 500GB Hitatchi drives in RAID 1) on which I store my VMs (there's more going on with it than just NAS things) and use the rest of the space for data. I need more space for it, since as we all know, 500GB is not enough. Firstly, how would you go about this? Secondly, do you have any tips on how to buy some harddrives on the cheap? It's a home NAS and archives will be dealt with differently (either I'll screw around with some LTO tapes or disc media, we'll see) so the harddrives, while I want to put them in RAID 5, they won't have to be "mission critical level of reliable". (Unless you have a different idea, if so then tell me) How much data will I need? Well, 3TB to start with, maybe a bit more and some room for expansion. I want to back up my personal computer (which has a 500GB HDD + 120GB OS SSD, that's how I know 500GB is nowhere near enough), another laptop with 500GB HDD, another one with a 1TB HDD and 2 other laptops with 200GB drives combined. The 500GB HDDs are considered to be full and the 1TB one to be 750GB full (for now) Then there are lots of VHS tapes that I will digitize and store on the harddrives and in the archive, photos and videos made by our family and so on so forth, pretty common cases. Any help you can provide is appreciated and any questions will be answered! Thank you!

Would be cool tho! If anyone has any other ideas, feel free to post them here!

So about a year ago I watched this video: This got me thinking. What and how can we use the satellites that are constantly above us for? Here are some things I know about: Internet connection - K, how do I get it in the middle of nowhere? What do I need for it? GPS tracking - Duh Sattelite phones - These even a thing anymore? That weather image downloading blew my mind, it's awesome! What can you think of and how would it be achievable?

Alright, after a long while I booted the server up again to test if everything is working and to update everything. Seems fine for now, but there is still an issue with mounting the network attatched storage both to Linux clients on the server and my Windows PC. The Windows PC problem seems to be an authentication problem. When I configure the network drive and connect as the "storage" user with the proper password, everything works fine, no problems. But when I restart, I have to authenticate again due to some error during authentication. Nothing changes, just that I have to put the password in again and it works fine. I might have missed something in Samba, any ideas? Second, when I followed this guide: https://wiki.ubuntu.com/MountWindowsSharesPermanently The part "Mount password protected network folders" I need to run the command "mount -a" every time I boot. How would I go about making that automatic? I am using that for my Turnkey mediaserver with Emby. Which otherwise works fine. Third problem I have is that my brother wants me to make a Metasploitable2 VM to run on the server. I downloaded the VM, which contained the .vmdk file and a few other vm files. Now here is the problem. I don't know where to put it. I went to the proxmox web UI, created a VM on the newest Linux kernel, with 1 GB RAM, a 30 GB harddrive, nothing special. But I don't know where it is located. I followed your video guide when I was setting the server up and my VMs are on this path "/main/vm/" which is on the mirrored ZFS configuration. I can see there are my container's harddrives and I can access them no problem, but I cannot see the Windows XP VM that I installed for testing. When I went to the path specified here: https://forum.proxmox.com/threads/how-to-upload-vmdk-file-to-proxmox-in-gui.21070/ I found an empty folder. Even when typing "ls -al" it's empty. No sign of the KVM files. I searched everywhere I know of and have no idea where to go now.

Thinkpads FTW! If I asked you how different are thinkpads and let's say Dell Latitudes, what would you say?

Well again, if you get a Wired Xbox One controller, you just plug it into the tablet and if it doesn't work you look around the internet for advice, just like now. If it's a wireless one, you just have to buy an additional USB wireless dongle and connect that to the OTG cable. Playstation 4 controllers use bluetooth so you don't need a dongle with them, but I think a wired Xbox controller is the easiest and cheapest to set up. Just go for it.

Wow, guys I just found this video: What the hell are you doing Dell? You found 1 weakness and promote your laptop this way?

I know, but I don't see why a "Thonk" pad...

Alright then. Let's talk bigger boys: The Latitude e6540 and e6440. The differences from what I know are that the e6440 has a 14" screen, less powerful dedicated GPU and... that's it from what I can tell. The e6540 is bigger, has a 15" screen, a pretty powerful dedicated GPU and more rigid display construction (the e6440 can flex a lot). Both are pretty big by themselves, however I am still thinking that I would have them in my backpack and use them on a table in a class, not on my lap really. My father still uses a e6540 which he got from work and from what I can see it is a very beautiful machine. It is pretty chunky though, but the 6440 is only a bit smaller, not thinner. Both have swappable batteries, they both have the swappable CD-ROM tray that can be swapped out with a 2.5" HDD enclosure, another 45Wh battery or with 2 USB 3.0 ports.

You wrote thonkpad 2 times, is that intentional?

Well it is a 12" laptop, I wouldn't think it would be that bad. Other option would be a Latitude e6440 which can have a HD+ or Full HD screen, a proper CPU with a quad core option, an extended battery, an awesome wi-fi antenna behind the display that might catch some wifi networks on the friggin moon (again, exaggerating, but it really is so good).

Still, I want a powerful desktop. It still has a lot better price/performance ratio and benefits like bigger screen, better audio, better keyboard, better ergonomics (mostly), even more customizability than the business laptops mentioned here and lots of other benefits. Now guys. May I ask what is wrong about a Dell Latitude e7240? Is the CPU really that much of a bottleneck?
