If you got a sweet deal on your 5700 XT or you desperately need a new GPU then it's obviously worth it. But as a guy who upped from a 1080 Ti (mostly the same performance level as 5700 XT) I'd recommend you going for something beefier. 7800 XT or 6950 XT, whatever is cheaper.
I know that the 7800 XT would be a better upgrade, but i feel that i won't use it to its fullest potential. Lately I've been playing less AAA games, instead, I'm mostly playing LoL, some competitive shooters (casually mostly), and some indie games. The 5700 XT is a great card, but I feel like it's at its last moments.
0. Your GPU as you stated above defaults at 140 W. This is the power it's limited by BIOS.
1. By adjusting voltage, you offset the voltage-frequency curve so your GPU hits higher clocks whilst staying in the same power level.
2. The lower you set your voltage the higher will be the frequency given you don't move the power limit slider.
All this leads to doing things this way if you don't need any speed boost and you're only hunting energy saving:
0. Reset the GPU to the stock values and monitor your GPU clock and wattage. Write them down somewhere or just remember them if your brain functions properly (unlike mine).
1. Move the voltage slider until you get stability issues and set it about 20 mV higher than that when you found an unstable one.
2. Decrease the maximum frequency slider until you get the frequency you had at stock settings minus 50 MHz (minus 200 MHz if you're hunting EXTREME efficiency whatever it takes).
3. Test if everything is still stable in every benchmark and game you can come up with.
4A. In case it is you start compensating lost performance with increasing VRAM bandwidth. Usually RX 6700 GPUs allow you to straight up max the slider out. 2110 MHz is possible on 100% GPUs.
4B. In case you have some stability issues you should increase voltage by 5 mV increments until it stops glitching/crashing/etc. Then you follow it up with increasing VRAM speed.
5. You are allowed to move your power limit slider to the left as well, yet this can lead to poor framerate stability: GPU doesn't crash but you don't feel smoothness anymore. You'd rather let it be at no offset position.
This is my Gigabyte RX 6750 XT GAMING OC 12GB undervolt result. Setting 1160MV cause unstable issue on daily usage (Playing video on YouTube/Facebook will freeze a little).
Temps when gaming Counter Strike 2 @ Room Temperature around 29Celsius (I live in South East Asia area and 29C is quite a cooling day):
Currently trying 2640MHz and lower. Used to be 2600MHz @ 1160Mv but had unstable issues.

Figured out the driver crashing issue using mGPU with RX 6700 XT and RX 6700. Simply swapping the cards and make the 6700 non xt primary did the trick.

For some reason, fast timings became stable for me. I don't know if it's the platform (LGA1200 ES → LGA1700 "normal" CPU) or drivers, but it's running rock solid for the whole night long. Never tested this driver on my last PC and can't test it because I don't have that CPU anymore.
Allowed ridiculous (300 W + 15%) wattage by MorePowerTool, yet the GPU still doesn't want to "eat" it. I don't see anything higher than low 200s. Higher frequencies, instead of leading to higher consumption, just crash everything to desktop. xD
It definitely can do faster than that but something (either insufficient voltage or something in BIOS) prevents my GPU from rocking 2950 (effectively 2880ish) MHz. I don't lack cooling, I don't lack VRM capacity, I don't lack PSU capacity. Will investigate.
Pushed it to the 2805 max clock (2730 to 2745 effective MHz). Crashes if I go 2810. Hm.
Ok, just hot swapped the cards. RX 6500 XT and RX 6700 XT are not compatible, no mGPU option. I tried with one of each as primary. Same after driver re-install just in case. I don't have a 6600/xT anymore. I sold em off a while ago.

I noticed Timespy works good to get closer to the desired clocks. Maybe Nightraid too, I'd have to double check that though. It seems RDNA2 is really geared to DX12_2 1440/2160P gaming. Mid ranged cards like ours 10 and 12gb vram is really sweet. At least this is was I notice running benchmarks often. Anything DX 11 and under, the card seems to slack the clocks for whatever reason.
I kinda disagree on this because it feels excessive at 1080p60 and can't fully utilise the 1440p 144 Hz displays, let alone 4K ones. 1440p60 is just why. Not fast, not high fidelity.
My current setup is a 4K monitor (60 Hz) and RX 6700 XT is really struggling with this resolution. I have to lower a lot of settings to get DX12_2 things run smoothly. Not to mention ray tracing is a complete no go at 4K with such a GPU.
So IMHO the sweet spot is RX 6800. This GPU has considerably more horsepowers than these cut-out 6700s.

Stomps my 2060's. Gotta say faster than 3060ti in some cases too. But I see your point. Decent mid ranged entry level card for the pricing though. The performance per dollar is good.
FCLK is overtuned by default. Running 1440 MHz instead of 1940 (red) and 1800 MHz (blue).
Lowering this to 1440 MHz decreased my GPU's power consumption by about 4 to 5 percent whilst I don't notice any performance loss whatsoever. Lowering to 1200 caused framerate instability at 4K (yet it was completely stable at 1080p).
Didn't help achieving my initial goal but saving a couple percent wattage is always welcome!
Just installed my brand new Christmas present to myself a 5800X3D and my FPS result in Hogwarts Legacy paired with the 6750 XT...........didnt change at all
