Physicals
Firstly, there's the physical stats of the Cybermen, who've frequently proved themselves to be physically stronger than The Doctor, or any Time Lord for that matter. For example, the Tenth Doctor, who is known for his physical strength, is on the verge of being overpowered while he's wielding a sword with both hands and the Cyberman is using both, and The Master is knocked out just by being on the very edge of one blast. In another instance, a Mark 5 Cyberman was about to kill the Fifth Doctor with a blow to the neck.
During the events of World and Enough Time and The Doctor Falls, it is heavily implied that Cybermen get more and more powerful through each newer generation, and during this same story line a "primitive" Mark I brings the Thirteenth Doctor, who is also known for his physical strength and endurance, to death's door right before he survives this absolutely massive explosio from its epicentre.
Note: For context, Bill Potts appears Human because she's deluded herself into seeing that way, and the audience are shown it from both her and The Doctor's perspective. In this episode, Bill is a fully-converted Cyberman.
Technology
In The Tenth Planet, a dying Mondas (Earth's twin) absorbs Earth's energy, and according to Krail, everything on the planet would just stop. However, the energy was far too much, and Mondas broke up
There's also multiple other instances of Earth-destroying feats: In The Coming of the Cyberme, they built a bomb capable of destroying Earth. In The Crystal Bucephalus, a Sontaran Stealth Raid destroyed the planet Tersurus (where multiple Time Lords have been, proving it's somewhat Earth-like) with an Earthshock bomb obtained from the Cybermen.
Now for the last part; the Durability Bypassing properties of Cyber-Bombs. In Earthshock, a Cyber-Bomb is capable of essentially depopulating the Earth
In The Flood, a far more technologically advanced Cyber-race exists. Their technology and designs are stated explicitly to surpass other forms of Cybermen. They also possessed a Vortex Reactor, which harnessed power from the Time Vortex.
In Supremacy of the Cyberme, a group of Cybermen from the end of the universe take over Gallifrey with Rassilon. They possessed all of Gallifrey's technology and were going to use the Regenerationn Energy stored in The Eye of Harmony to reset and alter time. They also destroyed all of Sontaran clone worlds and fleets, forced the Rutan to extinction, and reduced Alpha Centauri to a husk, along with creating terraforming arks.
In Real Time (watch here for the full webcast on youtube), the Cybermen existed so far into the future that small measurements of time lost all meaning. Their Cyber-Leader (Evelyn Smythe from an alternate time) was caught in a circular loop, where she would be sent back in time to create this new generation of Cybermen by infecting the Earth with a techno-organic virus. These Cybermen gained access to The Doctor's TARDIS, and used their newfound mastery of time to crush the Sontarans, Draconians, Time Lords and Daleks

- (Bill takes point, and three sonic devices are readied behind her. The lift arrives, the doors open, and a Cybus-style Cyberman is revealed.)
- DOCTOR: Fire!
- MASTER: Kill it, kill it, kill it, kill it! Kill it, kill it. Kill it.
- (They succeed between them.)
- DOCTOR: Missy, sonic the lift. Keep it here.
- BILL: Why's it different? Why does it look like that?
- MASTER: It evolved.
- DOCTOR: Exactly. Since we left, they've built a weapons-grade version to come after us. And we just gave our position away. Well done, the genius twins.

Technology
In The Tenth Planet, a dying Mondas (Earth's twin) absorbs Earth's energy, and according to Krail, everything on the planet would just stop. However, the energy was far too much, and Mondas broke up
- KRAIL: The energy of Mondas is nearly exhausted and now we turn to it's twin and will gather energy from Earth.
- BARCLAY: But but!
- DOCTOR: Gather energy?!
- KRAIL: Age, name and occupation.
- BARCLAY: But for how long?
- DYSON: My name is John Dyson, supervising engineer.
- KRAIL: Until it is all gone. Age.
- DYSON: But that means that the Earth will, will die!
- KRAIL: Yes. Everything on Earth will stop. Age, please.
- BARCLAY: But you can't calmly stand there and tell us we're all going to die!
- KRAIL: You are not going to die.
- DOCTOR: And how are you going to stop this energy drain from Mondas?
- LEADER: Cyberbombs, the most compact and powerful explosive devices ever invented.
- DOCTOR: Yes, and their use was banned by the Armageddon Convention.
- LEADER: Cybermen do not subscribe to any theory of morality in war, Doctor. Our calculations indicate that two bombs placed in the central fissure of Voga will fragmatise the planet.
- DOCTOR: Fragmatise? Oh well, I suppose we can't expect decent English from a machine.
- LEADER: Prime the buckles. Two bombs should be sufficient. Three will make certain.
- STEVENSON: Now what have they done?
- LEADER: The buckles are now primed. Any attempt to remove the harness before the countdown reaches the red zone will cause a secondary explosion. Do you understand?
- LESTER: You mean, if we attempt to release the harness before then, we'll get blown up.
- LEADER: Correct. It is as well to keep that thought in your minds.
- DOCTOR: And when we reach the centre of Voga, we'll be fragmatised, as you put it.
- LEADER: Point of impact.
- CYBERMAN: Twenty seven degrees seven minutes north, a hundred and sixty degrees twenty minutes east. The crust is weakest at this point.
- LEADER: Velocity at impact, ten thousand light units.
- CYBERMAN: Calculations indicate at maximum thrust, the Beacon will attain that velocity seven minutes before impact.
- LEADER: What explosive force is required to sunder the planet at that depth?
- CYBERMAN: One thousand kilos per unit.
- LEADER: Excellent. Then the plan will be executed.
- CYBERMAN: Yes, Leader.
- LEADER: Order the bombs to be transferred to the Beacon.
- (The Cyberman leaves through secondary control.)
- LEADER: The alternative plan will work. When the Beacon crashes into Voga, we shall be watching from a safe distance, but you will have a much closer view.
- (The Cyber Leader leaves by a side door. The Doctor beams in, stops and whistles. Sarah whistles in *return.)
- SARAH: Doc
- DOCTOR: (hiding) Shush.
- SARAH: Sorry.
- (Confident it is clear, the Doctor enters to untie her.)
- DOCTOR: You haven't seen anything of the Tardis, have you?
- SARAH: Tardis? Listen, Doctor, the Cybermen are loading this Beacon with bombs. They're going to smash it into Voga.
- LEADER: We must evacuate the Beacon in three minutes.
- CYBERMAN: Our calculations indicate the fireball will extend one point five million miles.
There's also multiple other instances of Earth-destroying feats: In The Coming of the Cyberme, they built a bomb capable of destroying Earth. In The Crystal Bucephalus, a Sontaran Stealth Raid destroyed the planet Tersurus (where multiple Time Lords have been, proving it's somewhat Earth-like) with an Earthshock bomb obtained from the Cybermen.
- 'I now have access. The last authorized research project into genetic experimentation began on Tersurus in the year 6198. It was fully funded by the Federation Scientific Executive.' 'And what happened to the project?' The Doctor had some very uneasy suspicions. 'A Sontaran stealth raid penetrated the frontier and destroyed the planet with an earthshock bomb in 6211.'
Now for the last part; the Durability Bypassing properties of Cyber-Bombs. In Earthshock, a Cyber-Bomb is capable of essentially depopulating the Earth
- DOCTOR: Magnetic clamp.
- ADRIC: Magnetic clamp. How much damage could this bomb do?
- DOCTOR: Enough.
- ADRIC: Enough for what?
- DOCTOR: To make life intolerable for the few who survived.
- PLANNER: We no longer need you. A Cyber-megatron bomb will be delivered. We must destroy life on Earth completely. Every living being.
- DOCTOR: Is this what you wanted? To be the ruler of a dead world?
- BENTON [OC]: It's news from the Doctor, sir, just come through on his open channel. They're going to drop some sort of bomb.
- BRIGADIER: Bomb? You mean the Cyberman are?
- BENTON [OC]: Yes, sir. Something called a Cyber-megatron bomb. They're going to wipe us all out, sir.
