Data Sources
Every figure on EquivalentTo is grounded in a published methodology or an authoritative public source. Here is where our data comes from, category by category.
Hardware and vehicle pages use real, current models with published headline specifications (cores, clocks, VRAM, horsepower, price). Benchmark-style scores (single/multi-core, AnTuTu, average fps) are normalized estimates intended for relative comparison, not absolute measurements. City price indices are approximate composite estimates. Corrections are welcome via the contact page.
AI Model Comparison
Large language models are compared on the MMLU benchmark (a widely-cited 57-subject test of general knowledge and reasoning, reported as a percentage), maximum context window, and published API pricing per million input and output tokens. Open-weight models can also be self-hosted. Benchmarks capture only part of real-world quality, which also depends on tool use, latency, safety and task fit.

Laptop Comparison
Laptops are compared on a normalized performance index (combining CPU and, where relevant, GPU capability), rated battery life, weight, display size, memory and starting price. Configurations vary widely, so we use representative base specifications; verify the exact configuration and current price before purchase.

Salary Equivalence
We build a composite price-level index for each city from official regional price parities and international purchasing-power parities across housing, food, transport and services, normalized so New York City = 100. The equivalent salary is your salary multiplied by the ratio of the destination index to the origin index. It estimates the income needed to hold real purchasing power constant and does not model taxes.

Processor Comparison
Each processor is scored on a normalized benchmark index aggregating single-core and multi-core results. Single-core predicts responsiveness and gaming; multi-core predicts throughput in rendering and compilation. We also report cores/threads, boost clock and TDP.

Graphics Card Comparison
Graphics cards are scored on a normalized game index measuring average frame rates at 1080p, 1440p and 4K across a representative title set, alongside VRAM capacity and TDP. Scores are relative and intended for comparison.
Primary sources
Smartphone Comparison
Smartphones are compared on a normalized AnTuTu performance score plus battery capacity, main-camera resolution, RAM and launch price. Real-world experience also depends on software and camera tuning.
Primary sources
Car Comparison
Vehicles are compared on manufacturer horsepower, combined fuel economy (mpg for combustion, MPGe for electric), 0-60 mph time, seating and starting price. Figures are indicative trims.
