Performance Analysis
The FP16 dense figure of 112.6 TFLOPS on the RTX 5080 stands at nearly twice the 58.3 TFLOPS dense figure on the RTX 4070 while the FP32 value of 56.3 TFLOPS likewise doubles the 29.1 TFLOPS value. This scaling supports faster training iterations and higher inference throughput when workloads remain in dense precision. Memory bandwidth of 960 GB/s versus 504 GB/s permits larger batch sizes before memory capacity of 16 GB GDDR7 becomes the limit. The RTX 5080 also lists FP16 with sparsity at 225.1 TFLOPS against 116.6 TFLOPS on the RTX 4070 so sparse workloads follow the same proportional gain.

When to Choose the RTX 4070
The RTX 4070 suits deployments where TDP must stay at 200W and PCIe 4.0 interconnect meets requirements. Its FP16 dense performance of 58.3 TFLOPS remains adequate for smaller models that fit within 12-16 GB GDDR6X while keeping total system power lower.
When to Choose the RTX 5080
Its 16 GB GDDR7 capacity and PCIe 5.0 interconnect support larger batches and faster data movement when training or inference scale beyond the limits of the RTX 4070.
Use Cases
The RTX 5080 provides FP16 dense performance of 112.6 TFLOPS and memory bandwidth of 960 GB/s which support larger batch sizes than the 58.3 TFLOPS and 504 GB/s on the RTX 4070.
FP16 dense performance of 112.6 TFLOPS combined with 960 GB/s bandwidth on the RTX 5080 enables higher tokens per second than the 58.3 TFLOPS and 504 GB/s figures of the RTX 4070.
The RTX 5080 lists FP16 with sparsity at 225.1 TFLOPS which doubles the 116.6 TFLOPS value on the RTX 4070 and allows faster adapter updates within 16 GB GDDR7.
Both GPUs deliver sufficient FP16 dense performance for image generation with the RTX 4070 at 58.3 TFLOPS and the RTX 5080 at 112.6 TFLOPS while memory capacity meets typical diffusion model needs.
FP32 performance of 56.3 TFLOPS and FP8 dense performance of 225.1 TFLOPS on the RTX 5080 exceed the 29.1 TFLOPS and 116.6 TFLOPS values on the RTX 4070 for simulation workloads.
Frequently Asked Questions
What FP16 dense performance does each GPU provide?▾
The RTX 4070 lists FP16 dense performance of 58.3 TFLOPS while the RTX 5080 lists 112.6 TFLOPS. These figures allow direct comparison of dense matrix operations without sparsity.
How does memory bandwidth differ between the two GPUs?▾
The RTX 4070 provides 504 GB/s bandwidth while the RTX 5080 provides 960 GB/s. The higher value supports larger batch sizes before VRAM capacity limits throughput.
What TDP values apply to the RTX 4070 and RTX 5080?▾
The RTX 4070 operates at 200W TDP and the RTX 5080 operates at 360W TDP. Power budgets must account for this difference when deploying multiple cards.
Which GPU offers higher FP32 performance?▾
The RTX 5080 delivers FP32 performance of 56.3 TFLOPS compared with 29.1 TFLOPS on the RTX 4070. This doubling benefits single precision scientific workloads.
Do the GPUs share the same interconnect generation?▾
The RTX 4070 uses PCIe 4.0 while the RTX 5080 uses PCIe 5.0. The newer standard doubles theoretical bandwidth for host to device transfers.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 4070 and the RTX 5080. 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.
