# Compute Resources

This brief article lists vendors and approximiate specification of league computing resources.

Below are the minimum specifications of league equipment. In for everything but the streaming computer, the minimum
specification is often driven by supporting a stable and smooth desktop environment.

## Truss Vision Computer (Next Unit of Computing - NUC)

The Intel NUCs are the truss computers. The league owns
[7th generation NUCs](https://www.intel.com/content/www/us/en/products/sku/97541/intel-core-i77567u-processor-4m-cache-up-to-4-00-ghz/specifications.html),
fist releasing in 2017. As such, their specification is quite modest.

- CPU:
  [i7-7567U](https://www.intel.com/content/www/us/en/products/sku/97541/intel-core-i77567u-processor-4m-cache-up-to-4-00-ghz/specifications.html)
  @3.5GHz [Benchmark](https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-7567U+%40+3.50GHz&id=2990)
- GPU: Intel® Iris® Plus Graphics 650
- OpenCL Version 3.0
- RAM: 16GB DDR4
- OS: Xubuntu 22.04 LTS

## Field Side Vision Computer

The league doesn't own field side computers. They are typically provided by the venue contract. Approximate minimum
specification is provided below:

- GPU: 4-core/8-thread Processor from within the last 5 years
- GPU: Integrated GPU
- OpenCL: Version 3.0+
- RAM: 16GB DDR5
- OS: Ubuntu LTS

When deployed as a vision processor host:

- 1-2x

## Game Controller Computer

The league doesn't own field side computers. They are typically provided by the venue contract. Approximate minimum
specification is provided below:

- GPU: 4-core/8-thread Processor from within the last 5 years
- GPU: Integrated GPU
- OpenCL: Version 3.0+
- RAM: 16GB DDR5
- OS: Ubuntu LTS

## Remote Controls

Remote controls are Raspberry Pi 4, 2GB or 4GB model. Accessory hardware (screens, PoE) is described on the
[ssl-remote-control repository](https://github.com/RoboCup-SSL/ssl-remote-control). These device need at least PoE+ to
deliver enough power.

## Status Board

Status board computers are Raspberry Pi 4, 2GB or 4GB model. Any computer capable of hosting a small webpage can fill
this role.

## Streaming Computer

The league doesn't own field side computers. They are typically provided by the venue contract. Approximate minimum
specification is provided below:

- GPU: 8-core/16-thread Processor >4.0GHz
- GPU: Nvidia 2060 or better, capable of 4k video transcoding
- OpenCL: Version 3.0+
- RAM: 32GB DDR5
- OS: Ubuntu LTS
