L4 vs RTX 2080 Ti

The L4 delivers 121 TFLOPS FP16 dense compared with 40.3 TFLOPS FP16 dense on the RTX 2080 Ti which produces a ratio of three times higher dense FP16 throughput on the L4. FP32 performance reaches 30.3 TFLOPS on the L4 against 10 TFLOPS on the RTX 2080 Ti. The L4 also provides 242 TOPS INT8 dense versus 161.1 TOPS INT8 dense on the RTX 2080 Ti. Memory bandwidth of 300 GB/s on the L4 family and 448 GB/s on the RTX 2080 family influences achievable batch sizes during training and inference workloads. The 72 W TDP of the L4 family versus the 215 W TDP of the RTX 2080 family further separates power efficiency between the two.

The L4 variant suits deployments that require 24 GB of memory capacity together with 121 TFLOPS FP16 dense throughput at a 72 W TDP. Workloads that benefit from the Ada Lovelace architecture and PCIe 4.0 interconnect favor this variant over alternatives with lower memory capacity.

The RTX 2080 Ti variant fits scenarios that utilize its 448 GB/s memory bandwidth and NVLink support even with only 11 GB of memory capacity. Applications that align with the Turing architecture and tolerate the 215 W TDP may select this variant.
