Is there a Jetson Thor-family module with less than 64 GB of memory? Looking for a cheaper Thor option.

Rapidflare · Accepted Answer

No, I couldn't find any Thor-family module with less than 64 GB of memory. The lowest-cost tier I found is the **Jetson T4000**, which has exactly 64 GB. It's a smaller Thor module than the flagship T5000, but it doesn't go below your 64 GB limit.

**Thor-family modules and kits**

| Product | Type | Memory | Max FP4 TFLOPS | Max AI TOPS (INT8, sparse) | Power |
|---|---|---|---|---|---|
| Jetson T4000 | Production module | 64 GB LPDDR5X | 1200 | 600 | 40–70 W |
| Jetson AGX Thor T5000 | Production module | 128 GB LPDDR5X | 2070 | 1035 | 40–130 W |
| IGX T5000 | Production module | 128 GB LPDDR5X | 2070 | not listed in the catalog | 40–130 W |

The other Thor products I found are developer kits and board kits, and all have 128 GB. They are the Jetson AGX Thor Developer Kit, the IGX Thor Developer Kit, the IGX Thor Developer Kit Mini and the IGX T7000. I also checked partner systems and carrier boards that support Jetson Thor, and none have less than 64 GB of memory.

**Jetson T4000 compared with the T5000:**
- **Cores:** 12 CPU cores and 1536 CUDA cores, against 14 and 2560 on the T5000. - **Memory bandwidth:** both have 273 GB/s. 
- **FP32:** 4.7 TFLOPS, against 8.064 TFLOPS on the T5000. I don't have pricing for these products. I can confirm the T4000 is a lower tier than the T5000, but not what it costs. For prices, please contact a Physical AI representative or an authorized distributor.
