Gigabyte GeForce RTX 4080 Super Gaming OC

[W1zzard]

Priced at $1050, the Gigabyte GeForce RTX 4080 Super Gaming OC features a massive triple-slot, triple-fan cooler that improves upon the thermal performance of the NV Founders Edition. The card also includes a small factory overclock and a dual BIOS with a quiet mode, offering both power and flexibility.

I can't say a $1050 GPU makes a lot of sense, but at least this one makes more sense than the stupid $1250 price tag on the Asus Strix model.

The Strix runs hotter, but very slightly quieter. I'm not sure either of these cards are above the noise floor in most homes.

Would undervolting help with reducing the noise further with quiet bios? Looking to pick up quietest 4080 Super, and this one seems sensible from cost perspective.

This is a fan curve problem, not a heat output problem. Just set a manual fan curve. The minimum fan speed on all modern NVIDIA cards is 30% though, the Gigabyte Quiet BIOS runs at 38%, so you're not going to have a ton of headroom

it's likely the minimum non-stopped fan speed set in the BIOS, since the quiet BIOSes favour warmer temperatures before increasing fan speeds.

The real question is what is your noise floor at home? 29dBA for the Strix is very quiet. 31dBA for the Gigabyte GamingOC is also very quiet. Unless your room is sound-insulated from external noise and you use speakers for gaming at low volumes, you're unlikely to notice.

You could use a decibel meter on your phone to check your background noise, but many of those don't do dBA, only dB.

Going on the basics, the Asus fan spins slower, but looks to have fewer vanes that must be more aggressively angled. In my experience that means it will be a lower, louder hum than the gigabyte at the same fan speed, but the more aggressive vane angle allows Asus to run the fan slower, which should cancel out the increased loudness of more aggressive vane angles.

Everyone's hearing is different, dBA scales attempt to emulate the 'typical' hearing so in theory the Asus should be quieter, but we're talking relatively low RPMs for both models using 110mm fans. Ultimately, the objective dBA recording is lower for the ASUS, you need to work out whether you want to spend $200 more for that.

When you say ASUS - do you mean TUF Gaming version? I'm currently leaning towards it, as it's "only" $100 more (tax included), which seems worth it for a slightly quieter card and better aesthetic. Planning to fit it into Fractal Design North, should still fit, even if tightly.

TUF, Strix, it doesn't really matter if you're after low noise.
I was talking about the Strix but the numbers for the TUF from W1zzard's temperature/noise roundup are pretty similar

Don't forget these are just default values and you can see Asus chooses hotter and quieter than Gigabyte, but you can always tune the fans yourself. If 1323 RPM is 38$ fan speed, I'm assuming 30% fan speed is ~1100 RPM, give or take a bit.

In the end decided to go with MSI Suprim, as it was the same price as ASUS TUF, and from the 4080 review, I saw it was excellent. Hope 4080 Super version will match it.

It should do. It's the same cooler, PCB, silicon, power limit, The 4080S is such a nothingburger of a launch that you can probably just take any 4080 review and apply it to the Super.

If you're bored, you could play a game of "Spot the Difference"

Perhaps a worthy observation: (All?) Gigabyte 4080 and 4080 Super models feature exposed copper base plate that directly contacts the GPU, and exposed copper heatpipes. I'm sure most other manufacturers use nickle plating even if it's not always obvious. But the direct copper contact gives this GB Super model a thermal advantage over the others.

Is it really an issue? I have a MSI 4090 running +260 core +1000 mem and the core clock stays locked, temps never pass 60c and the fans are running slow enough that it's silent at 3 feet and the 80's share the same size coolers but already run less hot. Honestly they should have gone with a 3 slot instead of the ridiculously large one.

I saw it in stock for a few hours at Best Buy today, but it's now sold out again.

does anyone know what kind of thermal paste this GPU comes with?
i heard and read stories most AIBs use cheap thermal paste that has to be replaced before even one year.
and if so, what thickness are the thermal pads because if i have to re-paste I'll probably need new pads also.

I definitely had to re-paste my old Asus 4070 Ti after a few months. Hot spot shot up into the mid-high 90s and I noticed it because the fans spin faster. The BIOS on these cards seem to take hot spot temps into account. Also, HWinfo reported thermal limit as a being triggered. After re-pasting, it helped a decent amount.

Now with this Gigabyte, I've never triggered the thermal limit in HWinfo even when I do a vulkan API run of Steel Nomad when over clocked. This is the most demanding, power-wise, "game" that I have. Even more than path tracing in other games. Specifically the Vulkan API, not the DX12.

I just did a run, and HWinfo reports:
370 Watts peak power
74° C peak GPU temp
92° C peak hot spot
Max fan speed at 70%
Only Power and Reliable Voltage limits triggered

This was done with my normal gaming OC, which is maxed out power limit. Maxed out voltage limit. +125 on the core. +1000 on the VRAM.

When not overclocked, this card got:
320 Watts peak power
67° C peak GPU temp
82° C peak hot spot
Max fan speed at 53%
Only Power and Reliable Voltage limits triggered

I don't see a need to re-paste this card yet. Although I don't remember the initial temps from the card when I got it new on the 4080 Super launch day.

Noticing in the data in the review the 4070 ti only 35w lower but has a proper sized cooler on it, 4080 has a 4090 cooler without the 4090 power draw.
