RapidBench T1 is a microbenchmark for testing "CPU speed". Scratch 2.0 and 3.0 compatible. [Press Space] to run the demo You will get a numerical score that tells you (relatively) how fast the user's computer is. This project reuses some code from eXtremeMark 2016, simplified to be tiny and portable. https://scratch.mit.edu/projects/100569167/ Just drop the "Custom_T1" sprite into a project to do speed tests. Provide the test duration (in seconds*), then just call the broadcast and wait. (*The test will take slightly longer [1-2s] to run than the time you specify) The score can then be used by your project to scale graphical effects so the project runs well. That's it. This thumbnail is also really cool. -------- Reference scores -------- CHROMIUM v70 - WINDOWS - SCRATCHv3 Intel 9900k (6-9 gen) - 5.5GHz - 150 Intel 8750h (6-9 gen) - 4GHz - 114 Intel 5y71 (5th gen) - 2.0GHz - 58 FIREFOX V72 - WINDOWS - SCRATCHv3 Intel 8750h (6-9 gen) - 4GHz - 60.6 FIREFOX v61 - WINDOWS - SCRATCHv3 Intel 8750h (6-9 gen) - 4GHz - 44 Intel 5y71 (5th gen) - 2.0GHz - 22 -------- Version Log -------- v1.2 - 01M/18D/2019 - Improve documentation, add demo, increase default test duration to 2s v1.1 - 07M/05D/2017 - Default test duration to 1s, add documentation v1.0 - 06M/02D/2017 - Release
