How long does a 150 GB game take to download at 500 Mbps?
42 min 8 s
to download 150 GB at 500 Mbps, best case. Typical: 50 min (at 80 % efficiency, our estimate for Wi-Fi and busy servers).
The biggest games now pass 150 GB. At 500 Mbps the store's servers and your disk may become the limit before the line does, so treat the typical figure as the realistic one.
The arithmetic
- 150 GB × 8 bits per byte = 1,200 gigabits (1,200,000,000,000 bits)
- 500 Mbps = 500,000,000 bits per second = 62.5 MB/s at most
- 1,200,000,000,000 ÷ 500,000,000 = 2,400 s = 40 min with zero overhead
- TCP/IP and Ethernet framing use about 5 % of the line (1,460 data bytes per 1,538 on the wire): 2,400 ÷ 0.949 = 42 min 8 s
If the size is really 150 GiB (some stores and Windows label GiB as GB), it is 7.4 % bigger: 45 min 15 s best case.
| Speed | Best case (95 %) | Typical (80 %, estimate) |
|---|---|---|
| 10 Mbps | 35 h 7 min | 41 h 40 min |
| 25 Mbps | 14 h 3 min | 16 h 40 min |
| 50 Mbps | 7 h 1 min | 8 h 20 min |
| 100 Mbps | 3 h 31 min | 4 h 10 min |
| 300 Mbps | 1 h 10 min | 1 h 23 min |
| 500 Mbps | 42 min 8 s | 50 min |
| 1,000 Mbps | 21 min 4 s | 25 min |
Sources and assumptions
- Overhead: 94.9 % efficiency from TCP/IPv4 on 1,500-byte Ethernet frames (computed); 80 % 'typical' is our estimate.
