Well I only have one monitor but it's a massive 5K2K (5120 x 2160) so I guess it depends on if it's specifically when there's more than one monitor or if it's just when there's a lot of screen.

Have you tested performance to prove it’s worse than the cheaper MBA or are you only looking at a boost frequency and drawing conclusions from that?

just checkd the specs for the pulse xt and its advertised boost frequency is 2450mhz, so if your card is around there or a bit more, it falls right in line with what the card is advertised to do, only the xtx's can push more (2600mhz+), better binning of the silicone, my red devil xtx with stock power limit hovers around 2575-2650mhz in most of my games, but when i add +15% to the power target my core jumps upto around 2900mhz and thats with no manual core adustments in wattman, every card is different, the xt you have looks to be right on the money in regard to its clocks
a MBA xt has a boost target of 2400mhz for reference

Thank you.. Do you think its a valid alternative setting the GPU clock limit around 2750 MHz? Or should I have to change some other parameters in this case?

Good summary there wookiee87.

I would think your PSU is capable. TPU review 100% ~817W from wall, 110% they test at ~904W from wall.
Sustained load your card can pull is ~435W, see this post, max peaks bit higher.
My system specs:-
R7 5800X3D (CO Tuned: -5 -9 -0 -4 -10 -21 -7 -14 142W 95A 140A 1x)
ASUS ROG Crosshair VIII Dark Hero
Crucial Ballistix Sport LT 3200MHz C16 2x16GB @ 3800MHz 1.35V 1:1:1 SOC 1.0V VDDG & VDDP 0.901
MBA RX 7900 XTX GPU min: 2648MHz GPU max: 2848MHz VRAM: 2748MHz VGFX: 1095mV PL: +15% FAN profile edited
2x WD SN770 Black 2TB NVMe
2x Samsung 870 EVO 4TB SATA SSD
9x Arctic Cooling F12 PWM fans
2x Be Quiet Silent Wings 3 140mm 1k (Set to full speed)
1x EK D5 Pump (50% PWM)
RGB on Bykski CPU block 6 LED 12V
RGB in case 42 LED 5V
Cooler Master V850 850W (not V2)
ASUS MG279Q, Cherry Keyboard, Logitech G700
So sustained load based on PPT 349W+15% = ~401W, above profile for my card.
Including screen (~30W), total rig, wall power plug meter reads when zero'd under load from 3DM TS ST, min ~486W max ~547W, idle for rig is ~104W.

yeah, i just did this. Is that bad?

I know it's time consuming but I'd set the power limit to 15 and turn off zero fan. Then set your boost clock to AMD spec which is 2400 (I think).
Run a benchmark at that speed and power limit then if everythings ok increase the boost clock by 100mhz incrementally and keep running the benchmark each time. When your score either gets worse or you get a crash wind it back 50mhz until it's stable.
Once you've done that try undervolting the card -25 each time repeating the same process as above.
Doing this I've managed to get a score of 3582 in Superposition 4k everything maxed.
My settings are...
7900xt MBA
Core boost - 2890
Power limit +15
Vram - fast timing
Vram clock - 2600
Core voltage - 1035
Max temps at junction is 90c.

Your VRAM clock doesn't go higher or lower gives better results? I run mine at 2750mhz+fast timing, haven't tried higher as it seems to be great enough.
Mine runs TimeSpy benchmark even with 1020mV, but in gaming 1040mV is stable.
How are your memory temps?
I only started playing with vram clocks last night after trying to get the core boost and undervolt sorted.
I'll play more with it tonight, I think I've still got a tiny bit of power headroom so I'll see if the memory has any more to offer. To be honest I just wanged it to 2600mhz to see
.I've not checked memory temps but I will do tonight. You seem to get much better benchmark scores by tweaking the memory. The only game I've had a crash on was star citizen but I don't think that's 100% on the card given the state of that game.

What's the asic and delta between edge and hotspot at idle?
So I played a little with the power limit on the silent Bios last night and the card will happily pull 408w and boost up to around 2940mhz when playing MW. I've got a small undervolt down to 1125 and just increased the power +10%.
Once I get some time later I will have a go at gaming on the OC bios at stock as I still haven't tried that. To be honest though I just need 175fps at 3440x1440 and this is pushing that out with ease in multiplayer and even hitting it in warzone on the silent bios so I should just save the power money

The day MBA was gonna come I had free day and guess what DPD deliver about 7pm...
Today I have to go out to work and DPD delivered about 8:30am...
As I passed the wife with the Nitro in my hands, she gave me the look!
And quietly asked is that another PC part...
I softly said yeesss...
LOOL...
Will spill the beans soon mate

Yes I am going to be moving to the silent BIOS, aside from YT videos where it'll be balls to the wall as usual. Any money that can be saved from energy is useful atm, over £4.50 here this was taken before 9:30am.So I played a little with the power limit on the silent Bios last night and the card will happily pull 408w and boost up to around 2940mhz when playing MW.

I can relate, to all of it.

Mine only shows me my gas - the electric doesnt work so I am in the dark (I kinda like it).
I just sit here in a jumper at home refusing to put the heat on all day (happy to smash out £1300 on a GPU though
)I hope someone can help me out. Just installed my new XFX Merc3100 7900XT (after many years of being nvidia user). I am currently in the process of learning the million and one settings in the Adrenalin software (the last time I used AMD it was called Catalyst). I am testing different games, and ran into a weird issue. Shadow of the Tomb Raider behaves like is not detected as a fullscreen game. The GPU sits in idle mode. Quick googling did not turn up anything useful, and reviews have tested this game and it ran fine, so it's something on my end.
I have tested the game in windowed mode and now GPU is running at max speed. Exclusive Fullscreen does not make a difference.

I just tested SOTTR and it seemed okay for me. Can you try pressing Alt+Enter to switch between window and full screen mode a couple of times?
You have a new £1300 400w heater nowMine only shows me my gas - the electric doesnt work so I am in the dark (I kinda like it).

Yes, when it's in windowed mode, works fine (except it's now in a window, obviously). When it's fullscreen, gpu usage is like it was in idle on the desktop, and frame rate just dies (I get 9 fps). Back and forth with alt+enter, same thing, window great, fullscreen dead.
