Best AI accelerators & GPUs

From data-center training silicon to the best consumer cards for running models at home.

Data-center flagship
NVIDIA GB200 / Blackwell class
The chip training the frontier models. For most people this is aspirational, but it's the benchmark everything else is measured against.
Full spec sheet →Check price →
Best consumer GPU for AI
NVIDIA RTX 5090 / 4090
The most capable card for running and fine-tuning models locally — huge VRAM and tensor throughput for the price of a workstation, not a data center.
Compare accelerators →Check price →
Best value inference
Apple Mac (M-series, high RAM)
Unified memory makes Apple silicon a surprisingly strong, power-sipping way to run large local models without a discrete GPU.

// Electric vehicles

Best EVs by need

Matched to how you actually drive — full range, battery and charging specs on the EV channel.

Best all-round
Tesla Model 3 / Model Y
Still the benchmark for range, charging network and software. The default recommendation for most first EV buyers.
EV spec sheets →Configure →
Best value
Chevrolet Equinox EV / Hyundai Ioniq 5
Long real-world range and fast charging at a mainstream price — the sweet spot of the 2026 market.
Full EV index →See every model →
Best 3-row family
Kia EV9 / Hyundai Ioniq 9
Genuine three-row space with 800V fast charging — the first EVs that truly replace a family SUV.

// Power & energy

Home battery & backup power

Store the sun, ride through outages, cut the bill. The chemistry behind each is on the Battery and Energy channels.

Whole-home
Tesla Powerwall 3 / Franklin aPower
The reference home battery — pairs with solar, backs up the whole house, and the app just works.
Battery chemistry →Check price →
Portable power
EcoFlow / Anker / Jackery power stations
LFP-based portable batteries for camping, job sites and emergencies — the gateway drug to home storage.
How storage works →Check price →
// Robotics & smart home

Robots you can actually buy

The consumer edge of the robotics wave decoded on the Robots channel.

Best home robot
Robot vacuum (roomba-class, lidar)
The one robot that's genuinely useful today — lidar mapping and self-emptying docks have made them set-and-forget.
Robotics index →Check price →
Best robot dog
Unitree Go2
A genuinely affordable quadruped — the same lineage as the research robots on the Robots channel, in a consumer package.
