Performance Analysis
The RTX 3090 delivers 71 TFLOPS of dense FP16 and 35.6 TFLOPS of FP32. The RTX 4060 publishes no dense FP16 figure and supplies only 15.1 TFLOPS of FP32. The resulting FP32 ratio favors the RTX 3090 by a factor of 35.6 divided by 15.1. Memory bandwidth of 936 GB/s on the RTX 3090 versus 272 GB/s on the RTX 4060 permits larger batch sizes before data movement becomes limiting. The RTX 3090 also lists 284 TOPS of dense INT8 while the RTX 4060 lists no INT8 value.

When to Choose the RTX 3090
The RTX 3090 suits workloads that exceed 16 GB of memory because it provides 24 GB of VRAM. Its 936 GB/s bandwidth supports larger batches than the 272 GB/s available on the RTX 4060. FP32 performance of 35.6 TFLOPS further favors the RTX 3090 when dense matrix operations dominate.
When to Choose the RTX 4060
The RTX 4060 fits environments constrained to 115W TDP because it draws less than one third the power of the 350W RTX 3090. Its PCIe form factor and lower thermal output allow denser node packing when FP32 throughput of 15.1 TFLOPS meets application needs.
Use Cases
The RTX 3090 supplies 24 GB VRAM and 936 GB/s bandwidth that accommodate larger models than the 8 to 16 GB and 272 GB/s on the RTX 4060.
FP32 throughput of 35.6 TFLOPS on the RTX 3090 exceeds the 15.1 TFLOPS on the RTX 4060 and supports higher token rates at batch sizes permitted by 24 GB VRAM.
Dense FP16 of 71 TFLOPS combined with 24 GB VRAM on the RTX 3090 enables fine-tuning runs that exceed the memory capacity of the RTX 4060.
The 936 GB/s bandwidth and 24 GB VRAM on the RTX 3090 sustain higher resolution batches than the 272 GB/s and 8 to 16 GB on the RTX 4060.
FP32 performance of 35.6 TFLOPS and 284 TOPS dense INT8 on the RTX 3090 provide measurable advantages over the 15.1 TFLOPS FP32 of the RTX 4060.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3090 and the RTX 4060. Dense and sparse throughput are listed separately.
- Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
- The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
