Performance Analysis
The FP16 dense figure of 59.5 TFLOPS on the RTX 3080 exceeds the 58.3 TFLOPS dense value on the RTX 4070 while FP32 remains close at 29.8 TFLOPS versus 29.1 TFLOPS which produces a consistent multiplication factor near two times for both GPUs in mixed precision scenarios. This delta supports training and inference tasks by allowing the same relative acceleration from FP32 baselines on either card. Memory bandwidth of 760 GB/s on the RTX 3080 compared with 504 GB/s on the RTX 4070 directly influences achievable batch sizes in memory bound operations with the higher figure permitting larger batches before hitting transfer limits. Sparse FP16 performance follows the same pattern at 119 TFLOPS versus 116.6 TFLOPS so ratios stay comparable when sparsity is applied uniformly.

When to Choose the RTX 3080
The RTX 3080 becomes the better choice for applications that require maximum memory bandwidth of 760 GB/s to sustain large batch sizes during compute intensive phases. Its FP16 dense performance of 59.5 TFLOPS also provides a marginal edge in dense tensor workloads where the 320W TDP is acceptable.
When to Choose the RTX 4070
The RTX 4070 serves as the preferable option in settings that prioritize lower power draw with its TDP of 200W while still delivering FP16 dense performance of 58.3 TFLOPS. Its VRAM range up to 16 GB further supports larger models without increasing bandwidth demands beyond 504 GB/s.
Use Cases
The RTX 3080 provides memory bandwidth of 760 GB/s which supports larger batch sizes than the 504 GB/s on the RTX 4070 during training passes.
The RTX 4070 operates at a TDP of 200W while maintaining FP16 dense performance of 58.3 TFLOPS suitable for sustained inference workloads.
Both GPUs deliver nearly identical FP16 dense figures at 59.5 TFLOPS and 58.3 TFLOPS allowing selection based on power or bandwidth priorities.
The RTX 3080 supplies higher memory bandwidth of 760 GB/s which benefits image generation steps that move large activation tensors.
The RTX 3080 lists an FP32 value of 29.8 TFLOPS which exceeds the 29.1 TFLOPS on the RTX 4070 for precision sensitive calculations.
Frequently Asked Questions
How does FP16 dense performance compare between the RTX 3080 and RTX 4070?▾
The RTX 3080 reaches 59.5 TFLOPS in FP16 dense mode while the RTX 4070 reaches 58.3 TFLOPS in the same dense mode. This small difference means both cards handle dense half precision workloads at similar rates.
What memory bandwidth values are listed for each GPU?▾
The RTX 3080 specifies 760 GB/s of memory bandwidth. The RTX 4070 specifies 504 GB/s of memory bandwidth. These figures determine data movement capacity independent of VRAM capacity.
Which GPU has the lower TDP rating?▾
The RTX 4070 carries a TDP of 200W. The RTX 3080 carries a TDP of 320W. Lower TDP reduces cooling and power infrastructure requirements.
How do the FP32 values differ?▾
The RTX 3080 provides 29.8 TFLOPS in FP32. The RTX 4070 provides 29.1 TFLOPS in FP32. The difference remains under one TFLOPS across the two cards.
Do the GPUs share the same interconnect?▾
Both the RTX 3080 and RTX 4070 use PCIe 4.0 interconnect. Form factors for both remain PCIe only.
Which is cheaper to rent, the RTX 3080 or the RTX 4070?▾
Cloud rental prices for both the RTX 3080 and RTX 4070 vary by provider, configuration, and availability. This page shows live pricing from 25+ providers updated every 60 seconds. Scroll to the Live Cloud Pricing section to compare current rates.
How much VRAM does the RTX 3080 have compared to the RTX 4070?▾
