Sapphire pulse

Great, i have the 7800 XT version of that card, good card....

 

[humbug]

Nice and snug in my nr200p

fits perfectly...

Runs great, silent pretty much too, never goes over 60 with 45% max fan speed

I would imagine so, as i said i have this one, as you can see its a smaller dual fan design, slightly lower TDP, i have higher core / memory clocks you have more CU's, out of the box it runs at about 245 watts at about 70c, perhaps slightly lower with 35% fan speed, its almost completely silent, day to day i run it overclocked with +10% power with custom fan curve of about 45% to keep the same temps, its more audible but still quiet.

I'm really impressed with it, its replaced an MSI 2070 Super Gaming X, which was twice the size with larger fans, despite that and despite using a little more power somehow it manages to run cooler and quieter than that GPU, its quite obviously not a high end GPU but the build quality is still good, it even uses thermal pads on the back of the GPU in to the backplate, something rare even among high end versions.

I think Sapphire just make really good GPU's, even if they are not high end ones, its as if they actually care about making a quality product.

GN never made a teardown of it, which is a shame, he did make a teardown of the RX 7600 version, which has the older version of this cooler type and fans, the whole thing is a little different to the updated version you and i have but its still a good measure of Sapphires thinking, which is interesting as first Steve thought the shroud was not attached properly and it seemed a little lose, turns out this was a design choice to make it easy to remove with the fans in it for easy cleaning. They stuck with that idea on our later versions and don't care that it feels slightly lose if you grab hold of it and pull it about, i do like the fact that you can take 6 easy to access screws out and the shroud comes off with the fans, easy to properly clean the dust out of it.

Sapphire Pulse, it's a great little card with only having 2 fans

Got the same card, fantastic little beasty...

 

[humbug]

Just picked up a 7800XT, was not really prepared for how large it is. Made my old graphics card look tiny in comparison.
Luckily fitted in my case, but was just contemplating getting a smaller case.

Need to do some testing now to see how good it is.

Which one?

 

[humbug]

Yes that’s the one. Now is it noticeable upgrade to 3070? Been looking at drivers thread on this forum and seems like nvidia does better job here, as I can’t remember if I ever had to complain about it’s software.

About 32%. 3080 Ti with 16GB.

AMD Radeon RX 7800 XT Review

With the Radeon RX 7800 XT, AMD is going after the GeForce RTX 4070. Our review confirms that AMD has achieved performance parity in rasterization and is pretty close in ray tracing, at a much better price point, and they are giving you 16 GB VRAM, instead of just 12 GB.

Looking at this chart it’s rather 24% at 1440p and 4k?

100% / 76% = 1.3157 (+32%)

 

[humbug]

Would love to hear what happens if you take 10% of the core clock, both in terms of performance but also power consumption. If its anything like RDNA 2 you will see good gains in powerdraw and heat with almost no penalty to performance. Mind giving it a shot and report back? im very curious.

I might try that when i have time.

 

[humbug]

TimeSpy control run stock: GPU score 19,372, 245 Watts.

-10% power, -100mv, core clocks locked to 2350 (you can see that is the data on the page) 19,298 identical pretty much, 205 watts.

This was a quick dirty try, with more fiddling i could probably get that down to 180 watts without any performance loss, these are not power hungry cards to start with and tuning them for low power works.

245 watts.

Man OCUK offered me a 7900gre for £400 on clearance and I turned it down in June.

Foolish foolish move

 

[humbug]

Anyone on here with a 7800xt that has high power draw?
I have one in my machine and one in the other half's machine and hers seems to draw about 50w less (280w vs 230w) with the same voltage, which seems bizarre to me, but it has a major effect on thermals, and obviously clock speed.

Anyone else noticed this too?

Depends on the model, the TDP of the RX 7800 XT is 263 Watts, my Sapphire Pulse is around 250 watts, that's the same as the reference version, however a high end one like the Sapphire Nitro+ is 277 watts.

So some might be a bit under the reference 263 watts TDP and some a bit over.

 

[humbug]

TDP is only a guide set by chip designer as to the 'minimum' cooling requirements, Nvidia do make AIB's stick to that power brief, its one of the reasons EVGA were unhappy with Nvidia, AMD do allow for a bit of discretion when it comes to power consumption so that's how you might get differences between model's.

If you want to bring the power down you could undervolt it and brig the power slider to -5% or so, its easy to do.
