The Jetson AGX Orin 64GB is the highest-AI-performance module supported on your AVerMedia D315. It delivers up to 275 INT8 TOPS (sparse), with a memory bandwidth of 204.8 GB/s (64 GB LPDDR5). nvidia.com +1nvidia.com ↗“275 INT8 TOPS (sparse)”nvidia.com ↗“64GB LPDDR5 (204.8 GB/s)”
For context, the D315 lists two supported modules: profession...professional.avermedia.com ↗“Jetson AGX Orin 32GB, Jetson AGX Orin 64GB”
| Module | AI performance (INT8, sparse) | Memory bandwidth |
|---|---|---|
| Jetson AGX Orin 32GB | 200 TOPS (Base) / 241 TOPS (Super) | 204.8 GB/s |
| Jetson AGX Orin 64GB | 275 TOPS | 204.8 GB/s |

- Both modules share the same 204.8 GB/s LPDDR5 memory bandwidth, so the 64GB module's advantage comes from its compute: 2048 CUDA cores / 64 Tensor cores and a 12-core CPU (vs. 1792 CUDA cores / 56 Tensor cores and 8 cores on the 32GB). nvidia.com +1nvidia.com ↗“2048 CUDA + 64 Tensor cores, 12-core”nvidia.com ↗“1792 CUDA + 56 Tensor cores, 8-core”
- The 32GB module has a published Super-mode figure of 241 TOPS; the 64GB module has no Super-mode figure listed, so 275 TOPS (Base mode) is the value to compare against. The 32GB's Super-mode figure still stays below the 64GB's Base-mode 275 TOPS, so the 64GB is the top performer either way. nvidia.com +1nvidia.com ↗“max_ai_tops_super=241 TOPS”nvidia.com ↗“275 INT8 TOPS (sparse)”
