Re: latest rpi-update 2.5ghz with 4B 4g

im running 2.0ghz from long time ago and the effective clock is 2.Ghz. Temperature cannot rise from 73C making the CPU stress test by hours. So I think that depend of the silicion, some can go higher.

Re: Test Comparisons on Raspberry Pi 4 on 1 GB, 2 GB and 4 GB models

Dont get crazy with bench etc. Just buy the 4Gb version if it will be your only RPi4 for everything, soon or late you will need the 4gb of ram. If you going to have more of one and they will have specific task, in that case you can choose other version to save some bucks.

Re: Pi4 as Desktop computer

Obviously rpi4 is a desktop computer, maybe like you or not how it looks, maybe linux dont like you and you prefer Windows, it is not a gaming computer or a workstation, but you can play, work and even earn a salary doing things with it.

Re: SLAM robot raspberry pi 4

Check the tutorial to overclock the RPi4 of TomHardwares and limit it to the speed you want, GPU included.
RPi4 CPU and GPUis made in less nanometers, it has more instructions,there is more functions can be made by chips as video compresion so at same speed, less power is needed

Re: SLAM robot raspberry pi 4

to make slam you need a 2D or 3d sensor and a software that can manage it, as ROS for example and most common and which I recomend you. There is different SLAM types. For 2d slam the most common is use 2D Lidars, but can be done with others sensors. 3D SLAM mainly is done with 3D Lidars, Stereo came...
