Notebookcheck

Our Rating Criteria

Here we explain which criteria is used in our test reports and what the single percent values represent. We rate the single categories as well as the end results in percent (0 - 100%). Here you can see our emphasis on the percent rates:

00 - 49 % - Insufficient
50 - 62 % - Sufficient
63 - 74 % - Satisfactory
75 - 87 % - Good
88 - 100 % - Excellent

Because retail prices partly significantly differ from each other and also quickly change, the respective price of a laptop is NOT included in our rating. So, it is up to the reader to judge about the current retail price of a reviewed notebook.
A table (including sub ratings) of all reviewed devices is available here: rating table.

Rating update in 02/2016, version v5:

A revision of our test criteria was necessary with the introduction of new processors from Intel (Skylake) and new high-end graphics solutions from Nvidia (Geforce GTX 980, 980 SLI). In course of this, we have also adjusted our criteria in connectivity, battery life, and display.

  • Connectivity: Revaluation of the incorporated interfaces taking into account new ports like USB type C. From now on, presence and performance of biometric access control, SD card reader, and WiFi direct have an influence on the connectivity sub rating, too. As for smartphones, we consider available communication features (LTE,...) as well as available sensors.

  • Battery life: Focus on realistic battery runtimes (WiFi test, video playback). Idle (max.) and load (min.) runtimes are no longer considered.

  • Display: Added the new measurements "response time" as well as PWM use to our rating.

  • Gaming performance: Changed the internal rating limits, because new high-end graphics chips from Nvidia are available. Changed benchmarks and games used for the evaluation.

  • System performance: Changed the rating limits. Changed the benchmarks and games used for the evaluation.

  • Workstation performance: Added a new sub rating for workstation notebooks.

Rating Update 14.03.2014, Version v4:

Thus far, the Notebookcheck rating system has graded on a weighted scale based on subratings such as notebook weight, performance, display and other specific aspects. Every subrating contributes to the final score with some subratings having more weight than others. This distribution between subratings has been independent of the category of the device in review.

  • From now on, subratings will depend on the category of the device. For example, an office notebook with a weight of 2.0 kg performs very well (91%) relative to its category, while a subnotebook with a weight of 2.0 kg would be considered heavy in its category and score only 65%.
    This same principle will apply to the Gaming, System Performance, Keyboards, Temperature, and System Noise subratings.

  • Because of advances in CPU and display technology, our evaluation of performance, display and battery life have also been made stricter.

  • The subratings "Audio" and "Camera" have been added to the rating.

  • From now on, the subrating "Impression" will have an indirect impact on the calculated total rating and will be displayed in the final rating more clearly as "(+/- XY %)". Essentially, the reviewer can bump the calculated score down or up depending on his or her final impressions of the device. If it is not displayed in the plugin, then the reviewer Impression had no effect on the calculated final score. This will also allow us to make corrections if the total rating does not reflect the overall impression.

  • The new weight distribution of each subrating is as follows on the table below. Our Display subrating in particular has been made more important to the final rating across the board in each device category.
