RTX 2080 Ti vs RTX 3080 Ti

TuringvsAmpereUpdated 35 days ago

The RTX 3080 Ti emerges as the clear winner for most common use cases like machine learning training and inference. Its 29.8 TFLOPS FP16/FP32 dwarfs the RTX 2080 Ti's 10.1 TFLOPS, enabling nearly three times faster processing, complemented by 760 GB/s bandwidth for larger workloads. The modest pricing premium from $0.08/hr versus $0.06/hr justifies the performance uplift in cloud environments.

Performance Analysis

The RTX 3080 Ti outperforms the RTX 2080 Ti significantly in compute capabilities, delivering 29.8 TFLOPS in FP16 and FP32 compared to 10.1 TFLOPS on the RTX 2080 Ti. This nearly threefold increase accelerates machine learning training and inference, enabling faster convergence in models reliant on half-precision or single-precision arithmetic. For training large neural networks, the higher FP16 throughput reduces epoch times substantially. In inference scenarios, it supports higher throughput for real-time applications. Memory bandwidth plays a key role: 760 GB/s on the RTX 3080 Ti versus 616 GB/s on the RTX 2080 Ti allows larger batch sizes without bottlenecks, improving utilization in data-heavy workloads like image generation or simulations. The RTX 3080 Ti's 10-12 GB GDDR6X VRAM edges out the RTX 2080 Ti's 8-11 GB GDDR6, accommodating bigger models or datasets directly. However, the 320W TDP demands more cooling and power compared to 215W, potentially limiting use in constrained setups.

When to Choose the RTX 2080 Ti

Opt for the RTX 2080 Ti in budget-sensitive deployments or power-limited environments. Its lower TDP of 215W suits edge computing or small-scale cloud instances where electricity costs matter. Pricing starts at $0.06/hr with an average of $0.11/hr across 6 offers, undercutting the RTX 3080 Ti's $0.08/hr start and $0.14/hr average. It handles lighter inference or fine-tuning tasks adequately with 10.1 TFLOPS FP16/FP32 and 616 GB/s bandwidth.

When to Choose the RTX 3080 Ti

Choose the RTX 3080 Ti for demanding workloads requiring high compute and memory throughput. The 29.8 TFLOPS FP16/FP32 performance excels in training and large-batch inference, while 760 GB/s bandwidth and 10-12 GB VRAM support complex models. Despite a 320W TDP and slightly higher pricing from $0.08/hr (average $0.14/hr across 4 offers), it delivers superior value for production-scale AI tasks.
