I'd use caution with the Mi50s. I bought a 16GB one on eBay a while back and it's been completely unusable.
It seems to be a Radeon VII on an Mi50 board, which should technically work. It immediately hangs the first time an OpenCL kernel is run, and doesn't come back up until I reboot. It's possible my issues are due to Mesa or driver config, but I'd strongly recommend buying one to test before going all in.
There are a lot of cheap SXM2 V100s and adapter boards out now, which should perform very well. The adapters unfortunately weren't available when I bought my hardware, or I would have scooped up several.
I've seen the sxm2 (x2) with pci extension cards out on ebay for like $350.
The 32gb v100s with heatsink are like $600 each, so that would be $1500 or so for a one-off 64gb gpu that is less overall performant than a single 3090.
Better to buy one used 3090 than those old cards. Everything is not vram. Or, you can do nothing without vram but you can’t do anything with just vram.
To use the second pair of pcie slots, you _must_ have two cpus installed. Just saying in case someone finds a board with just one cpu socket populated.
It depends on what you are doing and what compromises you are willing to take.
I'm still using my dell M6800 and t430 for work, they are decade old laptops.Ubuntu for Os and it's been working great. It's an i7 system and i work on php projects and sometimes dabble in python and some ml projects. Never ever disaapaointed me.
It's been showing it's age when some ml projects throw that the current cuda library is not supported by the nvdia graphics that i currently have.
I buy and sell used laptops and computers parts as my side hustle.
There afew points that you should keep in mind, while buying used laptop.
1.Don't buy U variants or any other low power variants of the i7 processor.
2.Don't buy dual core i7 variants.
3.Try to buy 8th gen or above. Better battery life and performance ratio.
4.If you are not everyday carrying or portablity is a must , stay away from slim and designer ones, that do not have adequate cooling.
5.Check if the display is TN or an IPS panel. TN is a straight no no.
6.Do not buy the models that are targeted towards students and home users, buy something that for professional users. They are more durable and tend to last long. Example lenovo T-series, W-series, HP also has some, Dell M-series, Precision-series.
7.Check the number of output ports.
8.Physical condition of the laptop, if it is kept clean or not. The fans might be clogged, hinghes are loose, some keys might not be working. Some usb ports might not be working or loose, etc etc
9.Reapply thermal paste , even if it's running fine. Factory ones dry out quickly, so you will get the chance to clean up the fans as well
Had the same thought, 0-100kmph in 3sec gives so much wheel spin.
Must be a whole lot of electronic trickery ever invented from launch control, traction control to power management plus the mechanical stuff sticky tyres, down force.
It amazes me how much faster we have got the last 6-7 years.
I'm thinking about a low budget system, which will be using
1.X99 D8 MAX LGA2011-3 Motherboard - It has 4 pcie 3.0 x16 slots, dual cpu socket. They are priced around $260 with both the cpu
2. 4X AMD MI50 32G cards - They are old now, but they have 32 gigs of vram and also can be sources at $110 each
The whole setup would not cost more than $1000, is it a right build ? or something more performant can be built within this budget ?
