so what your saying your going to be offering the motherboard for around 70 to 80 dollars? if not its hardly worth it. your still vetting out hardware so to say it will be cheaper in total supporting component costs per gpu is a bit premature. tbh I doubt this setup will be cheaper than compared to a typical 6 to 7 gpu setup not to mention your playin to a niche market and not everyone in that market will see that as viable, I see more points of failure being added etc, thats what I look at. but all in all I guess we all will find out
my question is what happens when you cant deliver on this promise your making that it will be cheaper and it turns out its not, you going to take a hit? doubt it lolz
That's not what he was saying, though...
Using the typical 6-GPU setup, the motherboard ($80), CPU ($40), RAM ($30), OS drive ($20), and risers ($50) add up to $220 (may be more or less depending on sales and availability, but this is about as low as you're going to go most of the time while using a free OS). Divide that by 6, and you have a per-GPU cost of $36.67. I'm not considering power supplies, because you'll need almost the same amount of power for either of these options, though needing only one ATX connection would further reduce costs. I'm also not considering the labor cost of setting up 3 systems with risers vs 1 system without risers.
For the 16-GPU board to be viable, the cost of the board, CPU, RAM, and OS drive combined must be less per GPU than $36.67. That means about $586, minus CPU, RAM, and OS drive (let's say ~$90 for those items). At around $500, this board would be comparable if you're using 3 consumer PSUs. If you're using one of the 4K + PICO PSU configurations, the board is comparable at $550-$600. If you are using a paid OS, you're saving 2x the cost of that, as well, so potentially $700-$800. Personally, I think the time and troubleshooting savings of not dealing with risers, and their myriad potential points of failure, is probably worth another $200 itself for bigger farmers.
I would be shocked to see a custom 16-GPU solution like this at $500, but even double that would probably have a good market among folks like OP.
