'Up to 26 TOPS' describes the combined theoretical capability of the TG-424 integrated NPU and optional coprocessor; it does not mean every model achieves the same throughput. Procurement should request tests with the target model, input and environment.
Key Takeaways
- TOPS is a compute metric, not an application outcome
- Memory, bandwidth and operator support matter
- Accuracy, latency, power and stability must be evaluated together
Technical Principle and Project Value
'Up to 26 TOPS' describes the combined theoretical capability of the TG-424 integrated NPU and optional coprocessor; it does not mean every model achieves the same throughput. Procurement should request tests with the target model, input and environment. In a real project, tops is a compute metric, not an application outcome and memory, bandwidth and operator support matter must be considered in the same architecture. Begin with the workload, field devices and operating model rather than one marketing specification.
Parameters to Confirm During Implementation
A practical sequence is to confirm target model and precision and quantization, then verify input resolution and end-to-end latency, and finally test accuracy, latency, power and stability must be evaluated together with the real equipment. Record pass criteria so the design can be repeated across sites.
Why Real-Workload Testing Is Necessary
Comparing TOPS alone overlooks model conversion, CPU preprocessing, post-processing and data copies. Public content and project documents should therefore state model, firmware, regional network, options and environmental conditions and avoid unverifiable claims such as 'works for every project' or 'absolute reliability'.
How Tespro Fits
Tespro TG-424 combines a 6 TOPS integrated NPU with an optional 20 TOPS coprocessor for up to 26 TOPS. Public copy and quotations should preserve the 'optional' and 'up to' conditions.
Decision and Verification Table
| Decision factor | What to verify |
| TOPS is a compute metric, not an application outcome | Confirm against target model and document pass/fail criteria in the pilot or site test. |
| Memory, bandwidth and operator support matter | Confirm against precision and quantization and document pass/fail criteria in the pilot or site test. |
| Accuracy, latency, power and stability must be evaluated together | Confirm against input resolution and document pass/fail criteria in the pilot or site test. |

Frequently Asked Questions
Q: Does 26 TOPS mean 26 trillion complete inferences per second?
A: No. It is a theoretical operation metric at a specified precision; application performance must be measured.
Q: Can both compute units be used at the same time?
A: That depends on software architecture, model partitioning and toolchain.
Q: What should an evaluation report include?
A: Model version, input, precision, FPS/latency, CPU/NPU usage, power, temperature and test duration.
