Quadro RTX 4000 vs T4

The dense FP16 rating of 65 TFLOPS on the T4 exceeds the dense FP16 rating of 57 TFLOPS on the Quadro RTX 4000 by roughly 14 percent while the FP32 rating of 8.1 TFLOPS on the T4 exceeds the FP32 rating of 7.1 TFLOPS on the Quadro RTX 4000 by roughly 14 percent. This ratio means the T4 can complete the same dense FP16 training or inference step in fewer clock cycles than the Quadro RTX 4000. Memory bandwidth of 416 GB/s on the Quadro RTX 4000 exceeds the 320 GB/s figure on the T4 so the Quadro RTX 4000 can sustain larger batch sizes in bandwidth limited kernels even though it holds only 8 GB of memory versus 16 GB on the T4. The 130 TOPS dense INT8 rating listed for the T4 has no counterpart published for the Quadro RTX 4000 so direct INT8 comparison remains unavailable.

The Quadro RTX 4000 suits workloads that require the 416 GB/s memory bandwidth figure to move data quickly through 8 GB of GDDR6. Scientific computing kernels that fit inside the 8 GB limit benefit from this bandwidth advantage over the 320 GB/s available on the T4.

The T4 suits workloads that require the 16 GB memory capacity or the 70W TDP limit. Inference tasks that scale with the 65 TFLOPS dense FP16 rating and the 130 TOPS dense INT8 rating run efficiently within the lower power envelope of the T4.
