GPU Tracker vs MetalScope

Stop opening 10 browser tabs to find the cheapest GPU. GPU Tracker watches prices across 10 cloud providers — AWS, Google Cloud, Azure, Lambda Labs, RunPod, Vast.ai, CoreWeave, Paperspace, Hyperstack, and Salad — and shows you the cheapest current rate for every major NVIDIA GPU. WHAT YOU CAN DO - Browse live prices for H100, H200, A100 (40GB and 80GB), L40S, L4, A10, RTX 4090, RTX 3090, and B200 - Filter by GPU model, pricing type (on-demand, spot, community), and provider - See a price history chart for any instance - Set price alerts — for example, "notify me when 1x H100 spot drops below $1.50/hr" - Get push notifications when an alert fires - Tap any offer to jump straight to the provider's booking page ASK AN AI ASSISTANT Describe your workload — "fine-tune Llama 3 70B for 12 hours" or "cheapest A100 for an experiment" — and our AI assistant (powered by Anthropic's Claude) recommends the best option with reasoning. It knows the live price catalog and considers your duration, GPU count, and reliability needs. WHO THIS IS FOR - ML engineers and researchers training models on a budget - Indie AI developers shopping for the best deal on inference - Startup founders watching cloud burn rate HOW IT WORKS We refresh prices every hour from each provider's public API or pricing page. Alerts evaluate every 15 minutes. The app is free to use. PRIVACY We store your email (for sign-in), your alerts, and your anonymous push token. That's it. No tracking, no ads, no selling your data.

MetalScope turns your iPhone into a professional GPU benchmarking lab. Run real Metal shader workloads and see exactly how your device stacks up against the entire Apple silicon lineup. COMPREHENSIVE BENCHMARKS Three precision tests built on Apple Metal API — compute throughput, render pipeline performance, and memory bandwidth. Each test runs multiple iterations to deliver stable, repeatable scores. INSTANT DEVICE SCORING Get a unified performance score the moment a benchmark completes. Sub-scores break down compute, rendering, and bandwidth so you understand exactly where your GPU excels. DEVICE RANKING Compare your iPhone against a built-in database of every Apple chip — from A11 to A18 Pro. See percentile placement and discover how your device compares across all dimensions. BENCHMARK HISTORY Track performance over time. Every run is saved locally with full details — scores, date, iOS version, thermal state. Spot trends and detect degradation. GPU INFORMATION Explore your Metal GPU capabilities: family, feature sets, core count, supported texture formats, and more. Know your hardware inside out. DESIGNED FOR ACCURACY - Low-battery warning prevents throttled results - Background app guidance for clean measurements - Multiple iterations reduce variance - Dark interface minimizes thermal impact during tests All data stored locally with SwiftData. No account required. No data leaves your device.
