Re: Pi 4 - full specification of VideoCore 6

Power consumption is about 3x what the raspberry pi 3B's is right? (~2.5watts vs 7.5watts) Why do we assume the die size is the same? Fortunately (or not, I suppose), the power figures hasn't changed that much from the Pi 3B+. https://www.tomshardware.com/reviews/raspberry-pi-4-b,6193.html And, the...

Re: Pi 4 - full specification of VideoCore 6

@jamesh Thanks! Each QPU has 2 ALUs, so Raspberry Pi 3's 12 QPU graphics processor actually has 24 ALU x 2 x 0.4GHz = 19.2GFLOPs, with a clock of 0.5GHz, you get the advertised 24GFLOPs. About the number of QPUs reported for Videocore 6, there is only 8 QPUs per register, with the Raspberry Pi 3, y...

Re: Pi 4 - full specification of VideoCore 6

- Technical information on VC. Is the VC6 an uprev of VC4 and so by-and-large compatible with VC4 software (e.g. open source compilers) or is the architecture significantly different? Are there more QPUs? More VPUs? Is the VPU instruction set similar? I notice OpenGL ES 3.0 is supported (up from 2....
