@Vader_Mester : do you have already some Benchmark results with S3 chip?

Not yet. I did not have time for it yet. I want to wait for the actual production samples to arrive, so I can test with something that should be valid for a longer time.

Some DSP related benchmarks of ESP32-S3 are available here: https://docs.espressif.com/projects/esp ... marks.html.

cheers,
"The Values in the column “O2” are made with compiler optimization for size, and in the column “Os” column are made with compiler optimization for speed."

O2 Os size/speed | Typo/swapped?


-Os

Optimize for size. -Os enables all -O2 optimizations except those that often increase code size:

-falign-functions -falign-jumps
-falign-labels -falign-loops
-fprefetch-loop-arrays -freorder-blocks-algorithm=stc



-O2

Optimize even more. GCC performs nearly all supported optimizations that do not involve a space-speed tradeoff. As compared to -O, this option increases both compilation time and the performance of the generated code.

-O2 turns on all optimization flags specified by -O1. It also turns on the following optimization flags:

-falign-functions -falign-jumps
-falign-labels -falign-loops
-fcaller-saves
-fcode-hoisting
-fcrossjumping
-fcse-follow-jumps -fcse-skip-blocks
-fdelete-null-pointer-checks
-fdevirtualize -fdevirtualize-speculatively
-fexpensive-optimizations
-ffinite-loops
-fgcse -fgcse-lm

-finline-functions
-finline-small-functions

Hi Folks,

ESP32-S3-DevKitC-1 with ESP32-S3-WROOM delivered from Digikey today.
and now on Desktop.

bootlog

FYI:
Digikey had the DevKits in stock and you had to be quick.
I managed to secure a handful and bought it; the shipment was very fast and arrived today. Happy happy -

Thanks Rudi, will fix.

Just to be careful, that these are from before the latest ECO of the silicon

This part is an engineering sample and is not fully tested. This part should only be used for functional evaluation and proof of concept, not for production or end use.

yes - they are engineering sample from Digikey/Mouser -
yes - the newer batch from espressif are newer one - with ECO patch.
Datasheet comes public out do Oct 28 from hearing

edit: added boot from hello_world_S3_Rev_O
BUILD: N256-R256_00 is my own ID for this ( becomes octal parts )

Just to be careful,...

was only little careful and broke the Board _
pimped ESP32-S3-DevKitC-1 (ESP32-S3-WROOM ) with external psRAM

Minimum free heap size: 8734063 bytes

You didn't break it, just upgraded it with 3D-Integrated circuit technology
Now THAT is development
Be careful posting it. Espressif might steal the idea to have better space budget on the WROOM modules

i work on that wait for the final
but first take a look to that bootleg - you find here a small difference to the previous post (handmade mod by add psram to flash ),
an AMAZING feature between the lines
( zoom example: right click on the picture - open it in a new Tab )
Yeap! ESP32-S3-N8R8 is here as a WROOM on the ESP32-S3-DevkitC-1-N8R8

@ESP_* Great ESP-IDF Work!!!!!
I noted, that the CLK will change in the future IDF. You can drive it up - 120 MHZ .. 266 MHZ - i am *hw* ready for it.

Cool

I'm curious about the support for the rgb interface screen mentioned in the esp32s3 datasheet. Is there any test for that?
