Performance Analysis
The RTX 4070 SUPER demonstrates a compute advantage with 35.5 TFLOPS in FP16 and FP32 performance: this represents a 19 percent increase over the RTX 3080's 29.8 TFLOPS, accelerating training and inference tasks in shader-bound workloads. However, the RTX 3080's superior 760 GB/s memory bandwidth, 51 percent higher than 504 GB/s, permits larger batch sizes essential for memory-constrained operations like LLM fine-tuning.
Power differences prove significant: the RTX 4070 SUPER's 220 W TDP versus 320 W enables lower electricity costs during extended cloud sessions. Ada Lovelace enhancements improve tensor core efficiency for inference, though bandwidth limitations may bottleneck data-heavy pipelines. These specs translate to the RTX 3080 favoring high-throughput scenarios, while the RTX 4070 SUPER prioritizes density and modernity.

When to Choose the RTX 3080
The RTX 3080 stands out for memory-intensive workloads: 760 GB/s bandwidth supports substantial batch sizes unavailable on the RTX 4070 SUPER's 504 GB/s. At $0.06 per hour starting price across four offers, it delivers cost-effective performance for tasks like Stable Diffusion generation or scientific simulations requiring rapid data movement.
When to Choose the RTX 4070 SUPER
The RTX 4070 SUPER fits efficiency-focused setups: its 220 W TDP cuts power draw by 31 percent from the RTX 3080's 320 W, ideal for dense cloud instances. The 35.5 TFLOPS compute and Ada Lovelace features enhance inference and hybrid graphics-compute applications, despite current lack of live pricing.
Use Cases
RTX 3080's 760 GB/s bandwidth handles larger batches better than 504 GB/s on RTX 4070 SUPER. This reduces training time for memory-heavy LLMs.
RTX 4070 SUPER's 35.5 TFLOPS and Ada architecture yield 19 percent higher throughput than RTX 3080's 29.8 TFLOPS. Lower 220 W TDP suits sustained serving.
Similar FP16/FP32 at 29.8 versus 35.5 TFLOPS fit most fine-tuning needs. Choose based on bandwidth for batch size or power for cost.
RTX 3080's 760 GB/s bandwidth accelerates image generation pipelines over 504 GB/s. Cheap $0.06 per hour pricing adds value.
Higher 760 GB/s bandwidth excels in data-parallel simulations versus 504 GB/s. 10-12 GB VRAM suffices for most workloads.
