GPU MODEL HELP! RX 7800 XT

[Wonky_irl]

Hi Everyone.

New forum poster here, so I moved away from Nvidia a while ago and have been pretty happy with AMD, so i'm upgrading my current GPU 6650 XT to a 7800 XT.

 

I need to decide on which 7800 XT to get, the choices are: (it's a length issue these are pretty much the only cards under 300mm~

Sapphire Pulse 7800 XT - £420

Gigabyte Gaming OC 7800 XT - £420ish

 

This is another reason why LTT labs will be so useful, there is basically no information on these GPUs other than reddit trolls who don't seem to know what they are talking about.

 

Does anyone own either of these GPUs, i'm really interested in thermals and noise tbh, and anything else you think might be helpful?

 

Cheers!

Here's some technical info on both:

• https://www.techpowerup.com/gpu-specs/gigabyte-rx-7800-xt-gaming-oc.b11400
• https://www.techpowerup.com/gpu-specs/sapphire-pulse-rx-7800-xt.b11402

The Gigabyte card is actually 302 mm in length, so slightly above the limit you cited. It's base clock is 25% higher, so it's going to require more power and likely be louder as a result. But should of course perform slightly better, though it's maximum clocks are only raised by 6% actually. Only review I could find of the Pulse is in German, so not sure that's going to help you.

What psu do you have? Make and model.

 

Else the gaming oc stuff is usually the low end coolers the pulse has a far better cooler and is generally very quiet whilst the gigabyte is just a budget version of gigabyte 7800xt

I'd suppose since the Pulse has 25% lower base clock it also sits at lower idle temps regardless of cooler?

 

but yeah, OC version probably better of having at least 750W PSU that's decent quality, on high-end Intel I'd even consider 850W

They have dynamic boost so at idle little to no difference.

 

The factory oc often also is just reached by any other card.

yeah but base is base regardless, so it'll just idle at higher clocks regardless one of them

Oh no base is not base actually. They'll happily idle lower. My pulse 7900gre sits happy at 300mhz ish idling away whilst its base is 1300.

 

Base clock only means minimal clock speed under fully load. Same like cpu's.

so base's the slowest turbo due to whatever reason it may base at that speed for? or perhaps the initial speed when it starts turboing before quickly going up?

Base is literally just the lowest guaranteed speed at 100% usage in the factory configuration.

 

It is often welllll beyond under what they'll be at at 100% load but that is by design so there cant be false claims
