GPU Gunnir ARC A770 16GB LP: Alchemist Rides Again

[Nilithium]

GUNNIR is working on a 165W TDP HHHL ARC card!

This thing would be great to have. I imagine the base render performance is worse than the RTX 4060 LP, especially considering the cut to TDP. However, the doubled VRAM buffer and PCIE 4.0 x16 bandwidth (alongside Deep Link capabilities) position this as a productivity card rather than a raw gaming card. The increased memory bandwidth (570GB/sec), Pytorch extension support and better VRAM/link speed also make this an attractive proposition for AI models as well, without breaking the bank on the market leader (RTX 4000 SFF). Plus, it even comes with a blower cooler, making it perfectly suitable for SFF prebuilts like the Lenovo PX Ultra series.

I'm only slightly interested, why do you ask?

@robbee Sorry, I meant to delete that first thread, just couldn't figure out how. On that, you are right that it's not quite half height. However, the way the layout of the Thinkstation P360 Ultra is arranged there's spare height available against the CPU cooler, so I'm hoping there's just enough room to smash that in!

That's one chunky blower fan for such a smallish card. I'd be interested to hear its sound profile. Like the raw industrial look of it

amazing card, and Gunnir unlike Sparkle keeps its promises and doesnt ship GPUs with messy, unfixable firmware. A770s however have an awful idle consumption, basically 40W when using 2 monitors that arent 1080p 60hz, or 3 monitors with whatever res so I woulve preferred a LP B580.

It looks like they took a centrifugal fan they usually use in full height blower card and then shrunk the cooler as much as possible around it. Unfortunately, it is still taller than half-height so won't fit in 99% of the low-profile cases

Sadely, but would be lovely with that combo :

nice find! just saw they also make a 600W buck converter...



unfortunately unobtanium products for us, I guess

Yes, I only linked the single 8pins as that GPU doesn't need more

Give it a try through the "enquiry button". Did that for another board and got a reply within a few days, they even offered me a prototype with patch wires as the board is this in development and might be cancelled in the end.

Thanks to you, I've successfully destroyed my dreams

Believe it or not, my particular case actually DOES support the extra 11mm vertically, because the card is laid sideways. There is extra clearance between the CPU shroud and GPU area to support it (pictures to come later).

The real deal breaker is the length of the card. The Gigabyte RTX 4060 LP measures L=182 W=69 H=40mm; the shroud at the length is only a handful of MM from touching the front of the case, but the PCB underneath is about 20mm shorter, which is where the the 8 pin converter board fits to power it (TL;DR proprietary PCIE to 8 pin).

At a monstrous 202mm, not even including the length added by the converter board atrach to the 8 pin, this thing doesn't have the clearance to fit. The PCB takes up the entirety of the card too, so the cooler can't be shaved down to compensate. Depending on the empty space behind the fan, I might have to see if the converter board can be soldered to the 8 pin connector and hide underneath the shroud of the GPU itself.
