How we calculate the score
The spec sheet becomes a score from 0 to 10, with public weights.
What counts toward the score
The score is the average of 5 components, each from 0 to 10. If the specs don’t list one of them, it drops out of the calculation and the weights of the others are redone; with too few components, the tablet gets no score. The weights are performance 30%, screen 20%, longevity 20%, battery and features 15% e recency 15%.
- Performance30%
Chip line and generation, from our own public table, and the RAM when the spec sheet lists it; with no chip identified by name, the tablet gets no score for this
- Screen20%
Sharpness (pixels per inch: the resolution for the size), refresh rate and OLED panel
- Longevity20%
Storage (a memory card helps below 256 GB) and the factory system version or the manufacturer’s update promise
- Battery and features15%
Battery charge per inch of screen, compatible pen, mobile data (4G or 5G) and four speakers
- Recency15%
Model year or, without it, the chip year

Public editorial order, not measured: the line and generation of each chip, from the strongest to the entry level. A chip not in the table ("Octa Core" with no name) gets no performance score.

What the score doesn’t consider
- Measured real-world performanceThe score uses our own table of chip lines and generations. The Radar doesn’t run benchmarks: two tablets with the same chip can perform differently.
- Real screen qualityBrightness, colour and glare are not in the spec sheet; the score looks only at sharpness, refresh rate and panel type.
- Real battery lifeThe spec sheet gives the capacity in mAh, not how many hours the tablet lasts or how the battery ages.
- Updates that actually arriveThe score uses the factory system version or the manufacturer’s published promise; the Radar doesn’t guarantee how many years of updates the tablet gets.
- Finish and accessoriesMaterial, case, pen and keyboard sold separately and their quality don’t count.
- Support, brand and the opinions of buyersRepair time, warranty and customer reviews are left out; check the store before you buy.
Two tablets with similar specs can perform differently. That’s why the score is for comparing tablets for the same use and at the same price level and finding where paying more stops paying off, not for choosing on its own.

How to read the score
It measures what the specs promise. A tablet with a recent chip line and generation, a sharp screen for its size at 120 Hz, 256 GB, a recent system, a big battery and a compatible pen ranks among the highest scores. An entry-level tablet, with a basic chip, 2 GB to 4 GB of RAM, 32 GB to 64 GB and a low-resolution screen, ranks among the lowest. The same calculation applies to every brand.
Performance has the greatest weight and comes from our own table, which gives a score to each chip line and generation. The table is public and is an order of magnitude, not a test: the Radar doesn’t run benchmarks or publish benchmark numbers. When the specs don’t list the data, the Radar doesn’t guess: the component drops out of the calculation.
Score from 0 to 10 calculated by the Radar from the tablet’s spec sheet (performance, screen, longevity, battery and features e recency). It doesn’t measure real performance, screen quality in use, real battery life, durability, support or what buyers think.
What does each axis of the chart show?
The chart always puts price on the horizontal axis. On the vertical axis you pick the question:
- Spec sheet: the 0 to 10 score on this page.
- Performance: only the performance component (Chip line and generation, from our own public table, and the RAM when the spec sheet lists it; with no chip identified by name, the tablet gets no score for this), from 0 to 10. It’s a spec score, not a lab measurement.
- Longevity: only the longevity component (Storage (a memory card helps below 256 GB) and the factory system version or the manufacturer’s update promise), from 0 to 10. It’s a spec score, not a lab measurement.
- Battery and features: only the battery and features component (Battery charge per inch of screen, compatible pen, mobile data (4G or 5G) and four speakers), from 0 to 10. It’s a spec score, not a lab measurement.
- Cheap for the specs: how far the price is below the median of tablets with a similar score (a difference of up to 0.5 points, at least 5 tablets). Only trusted sellers count, with prices that didn’t jump 20% or more between checks, and cases where a price-by-score curve also points to a price below what’s expected. The score comes from the specs, so brand and finish don’t count.
- Today’s finds: how far today’s price is below the median of recent days from the same seller. It only appears when there are at least 7 data points in the history, and a one-day drop only counts with a trusted seller or when confirmed in the next collection.
The chart line connects the tablets that no other beats on both price and the chosen axis. On the price difference axes there is no line: the biggest differences get named.
Where does the data come from?
The attributes come from the product listing on Amazon.com and, when the model is the same, from another store’s catalog; each piece of data keeps the source it came from. The price is the lowest among trusted sellers (Amazon.com, an Amazon.com seller rated 4.0 with 100 or more sales, or the brand’s official store) and shows the date of the check. The source of the score appears on screen next to each tablet. If we start using another source, this page and the screen say which one and since when.
How to read these numbers
The score runs from 0 to 10 and comes from the tablet’s spec sheet: performance, screen, longevity, battery and features e recency. The calculation is the same for every model and is on this page. It tells you what the tablet delivers on paper, not how it holds up in your day to day.
