Quick Verdict
Digitising a warehouse of 500,000 paper invoices is a batch OCR challenge where cost per page determines whether the project gets funded. PaddleOCR processes 476 images per minute at $0.0003 per image, while YOLOv8 manages 276 at $0.0005. On a dedicated GPU server, PaddleOCR finishes the same job in 60% of the time at 40% lower cost — a compelling combination for any large-scale document digitisation project.
YOLOv8’s value proposition is different: it excels at detecting and classifying visual elements (tables, logos, stamps, signatures) that PaddleOCR misses. For invoices with complex layouts, a pipeline combining both models outperforms either alone.

Specs Comparison
Both models are remarkably lightweight. PaddleOCR’s 0.8 GB VRAM footprint means you could theoretically run 30 instances on a single RTX 3090 for massive parallel throughput.
| Specification | YOLOv8 | PaddleOCR |
|---|---|---|
| Parameters | ~44M (YOLOv8x) | ~12M (PP-OCRv4) |
| Architecture | CSPDarknet + PAN | DB + SVTR |
| Context Length | 640×640 | Variable |
| VRAM (FP16) | 1.5 GB | 0.8 GB |
| VRAM (INT4) | N/A | N/A |
| Licence | AGPL-3.0 | Apache 2.0 |

Batch Processing Benchmark
Tested on an NVIDIA RTX 3090 with standard document datasets and maximum batch utilisation. See our benchmark tool.
| Model (INT4) | Batch tok/s | Cost/M Tokens | GPU Utilisation | VRAM Used |
|---|---|---|---|---|
| YOLOv8 | 276 img/min | $0.0005/img | 97% | 1.5 GB |
| PaddleOCR | 476 img/min | $0.0003/img | 96% | 0.8 GB |
Both models achieve exceptional GPU utilisation (96-97%), meaning they saturate available compute effectively. PaddleOCR’s 72% higher throughput reflects its lighter architecture processing more images in the same GPU time. See our best GPU for LLM inference guide.

Cost Analysis
At 500,000 pages, PaddleOCR costs roughly £18 versus YOLOv8’s £23.50. Both are extraordinarily cheap compared to cloud OCR pricing, which would run thousands of pounds for the same volume.
| Cost Factor | YOLOv8 | PaddleOCR |
|---|---|---|
| GPU Required | RTX 3090 (24 GB) | RTX 3090 (24 GB) |
| VRAM Used | 1.5 GB | 0.8 GB |
| Pages/min | 393 | 533 |
| Cost/10K Pages | £0.047 | £0.036 |

Recommendation
Choose PaddleOCR for bulk text extraction from document archives. Its 72% higher throughput and 40% lower per-image cost make it the default for any large-scale digitisation project. Its Apache 2.0 licence also simplifies commercial deployment compared to YOLOv8’s AGPL-3.0.
Choose YOLOv8 when your batch processing requires detecting visual elements beyond text — form field boundaries, table structures, logos, signatures, or other visual artefacts that inform downstream document understanding.
Run batch OCR overnight on dedicated GPU servers for maximum throughput at minimum cost.
Deploy the Winner
