[joe123]

Hello forum,

Tyan does offer several GPU Computing Platforms.  Some of them are:


Tyan Thunder HX GA88B5631 (B5631G88V2HR-2T-N)

4 Double-width PCIex16 slots for GPUs
https://tyan.com/Barebones_GA88B5631_B5631G88V2HR-2T-N

     vs.

TYAN FT77CB7079 (B7079F77CV10HR-N)
8 Double-Wide PCIe Gen3 x16 Slots for NVIDIA Tesla GPUs

My question:
Whats the difference between double wide PCIex 16 vs double wide PCIe Gen3 x16?


Thank's for any feedback!

If you scroll down to the section "Expansion Slots" you will see that both systems provide Generation3 PCI Express slots.
If you want to know the difference between the generations of PCIe check the Wikipedia page, differences mainly involve bandwidth. Double width means the physical size of the card supported: twice a single slot.

Thank you very much for the feedback. I should probably have asked :


- do both chassis support modern high powered GPU cards (like the 1080ti and 2010)?

PCIe is fully downward compatible.

Hi Joe,

If you check the GPU support list with *tested* cards you will see both servers support modern high power GPGPUs (Volta and Pascal). The FT77 there is already tested against an RTX6000 so you should have no worries as long as you keep your inlet air temperature low.
