A one-hour meeting transcribed in under ten minutes. That is what 6.2x real-time speed actually means in practice. We ran Whisper Large-v3 on the RTX 4060 through our standard benchmark suite on GigaGPU to see whether this mid-range Ada Lovelace card can serve as a serious transcription workhorse.
Processing Speed
| Metric | Value |
|---|---|
| Real-Time Factor (lower = faster) | 0.16 |
| Processing speed | 6.2x real-time |
| Audio hours processed per GPU-hour | 6.2 |
| Precision | FP16 |
| Performance rating | Good |
Benchmark conditions: FP16 inference, single-stream processing, 16kHz input audio, English language. faster-whisper backend with CTranslate2 optimisation.
Memory Profile
| Component | VRAM |
|---|---|
| Model weights (FP16) | 3.1 GB |
| Audio buffer + runtime | ~0.5 GB |
| Total RTX 4060 VRAM | 8 GB |
| Free headroom | ~4.9 GB |
Nearly 5 GB free after Whisper loads. That is a meaningful upgrade over the 3050’s tight margins — enough headroom to experiment with concurrent stream processing or co-host a lightweight Coqui TTS model (2.4 GB) for a complete speech-to-text-to-speech pipeline on a single card.
Per-Hour Costs
| Cost Metric | Value |
|---|---|
| Server cost | £0.35/hr (£69/mo) |
| Cost per audio hour | £0.056 |
| Audio hours per £1 | 17.9 |
At 5.6p per audio hour, the 4060 is the best cost-per-hour transcription card in our lineup. It processes 72% faster than the RTX 3050 while costing only £79/mo more. Commercial Whisper APIs typically charge 5-15x more per hour. Full comparison on the benchmark page.
Ideal Use Cases
The 4060 is the pragmatic Whisper card. Customer support call logging, daily meeting transcription, content studio workflows — anything processing 5-20 hours of audio daily fits perfectly. For real-time streaming transcription or larger backlogs, the 5060 Ti bumps speed to 8.3x. Full analysis in our best GPU for Whisper guide.
