eGPU history - Breaking the 25 GPU Cluster's record - 365 Gigahashes per second!

Today we have a win for the eGPU community. As you know, in 2012, a security firm presented a 25-GPU cluster capable of cracking 350 billion guesses per second, or 348 gigahashes per second, depending on which article you've read.

With help from watercooling and minor overclocking, a laptop eGPU setup set a record of 365 gigahashes per second.

You read right- four GTX 1080 ti in a Cubix chassis and two GTX 1070 in an MSI GT73VR laptop connected via Thunderbolt 3 wiped the floor with the networked 25-GPU cluster.

Psst...no SLI- quit asking.

Hats off to you, @mcarver316. This is incredible!

5 years later is a LONG time in the tech industry. I would expect a difference factor of about 6-8:1 between now and then. So 25/6 ~= 4 and 25/8 ~= 3 => Nowdays you're supposed to get the same performance with about 3-4 GPUs. All in the days work 🙂

mcarver316, such a historic moment could be published as a user-submitted news article on eGPU.io. Did you want to write and submit such an article? This being an evolution of the artechnica/hackaday articles. If so, consider adding:

  • your application requirement (eg: password cracking as a mobile solution)
  • hardware used: notebook, TB3 gear,video cards
  • configuration steps
  • performance achieved  (Gigahashes/s)

 

I'm aware there were several dips in the road to get this solution going. cough.. MSI BIOS .. cough

 Thanks- a bit of perspective. Thunderbolt 3 is limited to x4 lanes. The Cubix PCIe board has two Generation 1 PCIe slots and two Generation 2 slots, connected via x8 cable and Akitio Node board controller. eGPU IO has noted up to 20 percent performance loss with single eGPU via Thunderbolt 3, compared to the same GPU installed in a PC's native PCIe slot.

Just curious- Is there an article documenting 3-4 GPUs in 2017 performance equal to exceed a networked cluster of 25-GPUs in 2012?

Thanks- Perhaps third week of August on the write up?

The MSI BIOS is a pretty steep requirement. Installation process at least for the GT73VR is not for the faint of heart due to likelihood of bricking the laptop. I have also discovered there are way too many hurdles to just hacking around Windows to get this many GPUs to work, if at all possible. The modded BIOS has dozens of PCIe and Thunderbolt settings most of which I have no idea what they are used for. But here is a quick tried and true config for multi GPU setup after hours of trial and error.

- Thunderbolt Boot Support - enable
- PCIe Spread Spectrum - disable (Cubix requirement)
- 4GB Large Memory Support - enable (yes the BIOS has this setting!)
- Internal Video - enable
- Primary video - Internal GFX
- Secure Boot - disable
- Do not scan for external GPU upon boot - disable (if having problems booting with eGPU)

Excellent work!  Apple and everyone else involved have done a horrible job letting the public know about eGPU.

Plenty of end users out there will remember the 25GPU monster and have no clue that power is accessible today, at a fraction of the cost, in a portable package.

Been following this with great interest from day one - congratulations!

This is still a big deal in terms of reduced complexity, cost, licensing and operating considerations.

[edit] and when you factor in that a 1080Ti is not 6-8 times faster than a 7970... AND we're running 2 laptop GPUs - give some credit to what's been accomplished here.

It's okay. With the government moving to multifactor authentication, the Cubix idea might be outdated by the time it is ready.

This is a very relaxing side project- I learned so much and enjoying the process.
