GPUs & CPUs & Enthusiast hardware: Questions, Discussion and fanboy slap-fights - Nvidia & AMD & Intel - Separe but Equal. Intel rides in the back of the bus.

Does anyone else have experience with these cheap chink mini PCs? They seem like they would be a nice cheap option for a portable workstation, but I am always iffy on trusting chink shit, especially if their is malicious shit embedded in the bios.
If you buy from a site with a very good return policy like AliExpress or Amazon and read the listing very carefully for inconsistencies or red flags, you should be fine. But I was able to get a Lenovo m73 Tiny off Facebook marketplace, so check there first for something fairly new and powerful (unless stabbing is an issue)

AMD have ridiculously high idle power draws in general. It seems to come down to the memory controller, AMD consistently have worse IMCs than Intel, which is why all the RAM overclocking records are set with Intels, and why AMD tends to struggle just to drive two DIMM per channel at JEDEC.

This affects the Instinct GPUs as well. Nvidia GPUs can achieve the rated data throughput, and AMD's can't.

I use a Minisforum for my media center. S'alright, aside from the fact that it took me like 2 hours to figure out how to deactivate secure boot.

I'm double posting and Null isn't here to stop me.
 
Fellow NASfags, I want you to look at this and tell me it doesn't give you a boner.


What it would cost to populate it only makes me want it more.
They do make those with M.2 sleds for normal people. The controller is still going to be expensive, and the cables, etc.

But sadly that one is far too small. Here's a nice U.3 chassis.

You know what, I'm just going to leave it that way. Webp sucks.
 
This hasn't really been true in laptops. A major reason for this is that in laptop, the overall power management strategy and the design of the laptop itself matters a lot in total power efficiency, so efficiency benchmarks are often counterintuitive to what you'd think they'd be based on which chip was fabricated on which process node. The R9 8945 HS is, on a flop-per-watt level, under identical loads and identical clock speeds, more efficient than any Intel CPU on the chart (5% better than the Core Ultra 7, according to a chart in the article). But of course, things aren't identical, and in quite a few benchmarks, the specific ASUS ROG laptop it's in ends up gobbling a lot of power.

Example, Intel's new Core Ultras consume significantly less power when idling than AMD's do, despite using a less efficient compute-per-watt chiplet design. That probably won't affect these specific benchmarks, but it's a good example of laptop power management that you don't really care about in desktops or servers.

Is the laptop power management Intel thing due to single threading? Because I tend to agree. As long as I'm not doing too crazy with my i5, it can last on battery for quite a bit, and it's not a big laptop, the battery isn't huge.
 
It's not like a mobile i5 is going to really be burning a lot of juice anyways, at least it shouldn't be.

Now these i9s otoh....
I mean it will when you're streaming 1080p video with the brightness up. Still you should be able to make it through a 2 hour movie with a hour to spare in my experience.
 
That sounds like pretty crappy battery life.
It's a small buisness laptop running win 11. It's battery is tiny and runs hot because small fan. That said, it does get through a entire movie on battery. It could be worse. I'm always told a x86 laptop is supposed to die 30 seconds after you unplug it from the wall.
 
The guy on Facebook selling 8TB SAS drives has dropped his price to $60cad/$45usd each. I can juuust afford to pick up two now and double my server storage space, and possibly a few more when I get my paycheck in a couple weeks. Just need to determine how much to push. Maybe I can get a bulk discount, but $350usd for 8x8tb drives seems a good price
 
whelp, neither works. I know the drives are good as I've bought all my other drives from him, but these ones don't even register in lsblk or the raid card management software. I guess my raid card cannot handle 12Gb/s drives :(

edit: it can, but it can't handle 4k 512e drives. which my 6tb claims to be. so it's probably the 12Gb/s part.
I do need to upgrade my raid card and I guess now is as good as time as any, I just have to make sure I choose the right one

Wasn't the interconnect on a larger node than the rest of the chip for their CPUs? I wonder if that's the thing here too.
AMD consistently have worse IMCs than Intel
Intel always beat AMD on L1 cache and branch prediction.
 
Why would you use a RAID card in this day and age, thats not been a thing for like 10 years bro
Because I need something to connect to the backplanes that all my drives are connected to, and all the connector cards seem to be SATA only
 
Yes, by not flushing misses, which gave us one of the biggest security holes in the history of computing.
Explain what you mean, this sounds interesting.

Ah. The lack of SATA slots strikes again

You should get a sata expander and do software raid, that way amongst other things its definitely recoverable if the expansion card perishes
