GPU Comparison Tool: Compare Performance, VRAM, Price & AI
Compare two GPUs side by side across gaming performance, VRAM, memory bandwidth, power efficiency, price and local AI suitability. Choose the workload that matters most and see which GPU has the stronger overall profile.
The calculator methodology, comparison structure and dataset assumptions were reviewed for this tool. Performance values are normalized comparison indices and are not guaranteed FPS results.

Which GPU Makes Sense for Your Workload?
Match the Resolution
Compare the performance index at the resolution you actually intend to use. Then consider VRAM, power requirements and purchase price.
Check VRAM First
VRAM capacity can determine which model sizes and context configurations are practical for local AI workloads.
Look Beyond FPS
Rendering and creative workloads can depend on compute, memory capacity, software support and application-specific acceleration.
What Does the GPU Performance Index Mean?
The performance index is a normalized comparison score used by this calculator. It is designed to make relative GPU performance easier to compare and is not an FPS measurement.
The calculator uses separate normalized scores for 1080p, 1440p and 4K. This allows the comparison to reflect the selected resolution rather than treating every gaming workload as identical.
Power Efficiency & Value
Local AI & LLM Suitability
How Much VRAM Do You Need for Local AI?
VRAM is one of the most important specifications to check when comparing GPUs for local AI and LLM workloads. A model's parameter count alone does not determine its complete memory requirement.
Actual memory usage can also depend on quantization, context length, KV-cache requirements, framework overhead and other runtime allocations.
Therefore, the AI guidance in this tool should be treated as a starting point rather than a guarantee that a particular model will run within a specific VRAM capacity.
Methodology & Data Transparency

Performance scores are normalized comparison indices based on the dataset used by this calculator. They are not manufacturer claims and should not replace independent reviews or workload-specific testing.
Hardware specifications such as VRAM, memory type, memory bus, bandwidth, power rating, architecture and launch MSRP are represented from the dataset used by the tool.
