100Mbps vs 1Gbps vs 5Gbps — what's marketing and what's measurable. Fiber vs cable vs 5G home internet, with current 2026 pricing across all major US providers.
"You need gigabit" has become the default advice from providers selling gigabit plans, which is a conflict of interest worth noticing. For the vast majority of households, the actual bottleneck isn't download speed — it's upload speed, latency during peak hours, or simply having more devices than your old plan's tier was ever designed to handle.
100Mbps, 1Gbps, and 5Gbps aren't a smooth continuum of "better" — each step up matters for genuinely different situations, and most homes plateau in real benefit somewhere well below the top tier being advertised. Knowing where your household actually sits on that curve is the entire decision.
Three fundamentally different infrastructures, each with a real strength and a real weakness.
| Type | Typical Speed Range | Avg Price/mo | Latency | Availability |
|---|---|---|---|---|
| Fiber | 300Mbps–5Gbps | $50–90 | Lowest (~5-10ms) | Limited but expanding |
| Cable | 100Mbps–1Gbps | $40–80 | Low-moderate (~15-30ms) | Widely available |
| 5G Home Internet | 100–300Mbps (varies) | $35–60 | Moderate (~20-40ms) | Growing fast, no contract typical |
The table tells you the numbers. This is what each connection type is actually like to live with day to day.
Work through these before signing up for anything advertised as "blazing fast."
The numbers that actually matter, versus the number on the marketing page.
| Activity | Recommended Download | Recommended Upload |
|---|---|---|
| Web browsing & email | 25Mbps | 3Mbps |
| 4K streaming (1 stream) | 25Mbps | 3Mbps |
| HD video calls | 10Mbps | 3-5Mbps, critical |
| Large household (4+ devices) | 200-500Mbps | 20Mbps+ |
| Cloud backup / large uploads | n/a | 50Mbps+ recommended |
Need symmetric speed and the lowest latency, and it's available at your address — fiber is worth it. Fiber isn't available, but you want broad reliable coverage — cable remains the safe default. Want simple no-contract setup with adequate speed — 5G home internet is increasingly viable as a primary connection, not just a backup.
Whatever you choose, the activity table above matters more than the headline speed number on any provider's homepage.

Gigabit mostly helps very large households with many simultaneous heavy users, or anyone doing frequent large file transfers.
Gbps is simply 1,000 times larger than Mbps — a 1Gbps plan is the same as a 1,000Mbps plan. Providers sometimes switch units between plans specifically to make the bigger number look more impressive on a pricing page.
For many households, yes — but reliability depends heavily on proximity to a cell tower and local network congestion, which varies address to address. Testing it during the provider's trial period is the only reliable way to know for your specific location.
Cable's underlying technology (DOCSIS) was originally designed around asymmetric usage — heavy downloading, light uploading — a pattern that's shifted with video calls and cloud backups but hasn't been fully redesigned around in most cable infrastructure.
It can — 4K streaming uses meaningfully more data per hour than HD, and a household with multiple simultaneous streams can hit a low data cap faster than expected. Check whether your plan has a cap and what the overage policy actually is.
Each major fiber provider has an address-lookup tool on their site that gives a definitive answer for your specific location — availability changes frequently as buildout continues, so check directly rather than relying on outdated information.
Less often than it used to be, as streaming has reduced the value of bundled TV for many households. Compare the bundle price against standalone internet plus your actual streaming subscriptions before assuming the bundle saves money.
