# Performance

## Version 2.2.0

Version 2.2.0 maintains the same performance characteristics as Version 2.1.0. All performance benchmarks and accuracy metrics from Version 2.1.0 apply to Version 2.2.0.

## Version 2.1.0

Version 2.2.0 maintains the same performance characteristics as version 2.1.0. All performance benchmarks and accuracy metrics from version 2.1.0 apply to version 2.2.0.

For detailed performance comparisons and benchmarks, see the [Version 2.0.0](#version-200) section below.

## Version 2.0.0

Compared to Version 1.0.0, Version 2.0.0
  - Removes HHR-based template processing and
  - Adds TensorRT support for a wide set of GPU architectures. Refer to the Release Notes.
  - Adds support for 'explicit_templates'. Refer to the [Migrate from HHR-based Templates to Explicit mmCIF Templates](/nim/bionemo/openfold2/2.2.0/migrating-from-hhr-to-explicit-templates).

### Performance and Accuracy

- **Faster startup**: Reduced initialization time due to removal of large template database loading (~300GB)
- **Enhanced GPU support**: TensorRT optimization for L40S, B200, and RTX 6000 Ada Generation
- **Reduced storage footprint**: Container and cache requirements significantly reduced (from 380GB to 80GB total)

#### Performance Comparison (Time in seconds) on H100

- Below are benchmark times, measured for each input chain, in sequential execution on a single **NVIDIA H100 80GB HBM3** device.

*pipeline_time is defined as the time to load parameter sets, compute features, and the sum of the time
to complete the forward pass for each model in [model_1, model_2, model_3, model_4, model_5]

## Version 1.0.0

Performance will also vary significantly depending on:

- The type of NVIDIA GPUs that are attached and available to the NIM
- The CPU type
- System RAM available

The following section details some performance expectations and provides general tips. These are not meant to be indicative of expected performance
 and performance on your system will vary from these values.

### Recommended System Requirements

 - Refer to [Supported Hardware](/nim/bionemo/openfold2/2.2.0/support-matrix) for requirements.

### Performance Benchmarks

The following are performance benchmarks for OpenFold2 version 1.0.0.

- Structure prediction performance is mostly dependent on GPU capability and memory. If you find structure prediction to be a bottleneck, consider using a higher memory device.
- The time required for structure prediction grows with sequence length.
- The time required for structure prediction grows with the total number of sequences in the alignments.
- Below are benchmark times, measured for each input chain, in sequential execution on a single **NVIDIA H100 80GB HBM3** device.
- The average value of LDDT-CA, for these protein chains, averaged over 2 runs, is 0.86.
