What is official FP4:FP8 FLOPS ratio on Blackwell?

Thanks for your reply. Then if I use torch.mm api to test FLOPS, how can I specify the acc data type?

How should we tune Jetson AGX Thor for a CPU-bound web server workload (700 concurrent users), and can the GPU contribute anything?

2026-09-09T12:06:56.000Z · @chirag.lakshmipathi1 Chirag Lakshmipathi

We are hosting a school management web application on a Jetson AGX Thor Developer Kit as an on-premise appliance for a single campus. It is a conventional three-tier server workload, not an inference workload, which is why we are unsure how much of the usual Jetson tuning guidance applies to us.

Nanodeoclus: This is not the case on workstation (RTX Pro) Is that true even if they have the same CC? For example, both RTX Pro 6000 Blackwell and RTX 5090 are CC 12.

Some other factors you have to be careful about, when interpreting FLOPS numbers: clock: base vs. boost clock unit: FFMA operations or floating-point operations. 1 FFMA instruction or operation counts as 2 FLOP / floating-point operations (multiply and add) matrix-format: sparse vs. dense calculated on which hardware compoinent: conventional arithmetic units vs. TensorCores vs. both together

Believe me, I know exactly what you mean. I used to get very angry with Claude on a daily basis. I had my fair share of ranty swearing sessions at various Qwen models. I don’t tend to get angry at ds4flash at all as it mostly just works - follows my workflows, tells me if it can’t do something, and I don’t see the hallucination that a lot of people say is there with the model. Perhaps that’s the w

Is UART4 Function Available on Jetson Thor UART4_TX/UART4_RX Pins?

2026-09-09T10:20:12.000Z · @jeonghong0.lee Jeonghong0 Lee

The pins are named UART4_TX and UART4_RX in the Jetson Thor pin description. However, UART4 is not listed in the Design Guide, and I cannot find any UART function for these pins in the pinmux spreadsheet. Can these pins be configured as UART4 and used as a standard UART interface, or are they reserved for internal use only?

What is official FP4:FP8 FLOPS ratio on Blackwell?

2026-09-09T10:18:32.000Z · @Nanodeoclus

On consumer GPUs (GeForce RTX) the peak performance not only depends on the A/B types (input matrices) but also on the C/D type (output/accumulation matrix), i.e. whether you are using FP16 or FP32 accumulation. This is not the case on workstation (RTX Pro) or datacenter GPUs, where peak throughput is the same for FP16 and FP32 accumulation. See appendices in this document for detailed GeForce RTX
