The buying question

Should you match your existing receiver or change the connection plan to get backlit keys?

K780 supports Unifying but has unlit keys. K98M supports Bolt and adds white backlighting. Both also offer Bluetooth.

Quick verdict

When to skip: You require both Unifying receiver compatibility and built-in key backlighting in the same keyboard.
When the recommendation changes
  • If you need lighting but own a Unifying receiver, consider K98M only with a separate compatible Bolt connection or compatible host Bluetooth.
  • If Bluetooth suits your host, receiver family becomes less important; decide whether key illumination matters.

The differences that matter

Receiver Ecosystem Eligibility

Logitech K780 Multi-Device Wireless Keyboard (920-008025)

Unifying receiver or Bluetooth Smart; not compatible with a Logi Bolt receiver.[2, 5]

Logitech Alto Keys K98M Wireless Mechanical Keyboard (Graphite, 920-013575)

Logi Bolt receiver or Bluetooth Low Energy; not compatible with a Unifying receiver.[3, 5]

What this changes: Check the receiver family before choosing. K780 matches Unifying; K98M matches Bolt. Bluetooth is an alternative for either keyboard on a compatible host, so a receiver mismatch alone need not rule it out.[2, 3, 5]

The better fit depends on your priorities

Key Backlighting

Logitech K780 Multi-Device Wireless Keyboard (920-008025)

No key backlighting.[2]

Logitech Alto Keys K98M Wireless Mechanical Keyboard (Graphite, 920-013575)

White key backlighting.[4]

What this changes: Choose K98M when illuminated keys are a requirement. If you do not need lighting, decide by connection fit rather than assuming backlighting improves typing.[2, 4]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare current offers for the exact variants and any separately needed receiver. A higher price is worth considering only if the connection family or key lighting solves your setup need.

There is insufficient price history here to judge whether the current offer is unusually favorable.

Limitations

  • This is a documented-feature comparison. No hands-on typing, sound, latency, battery-life or comfort comparison was performed.
  • Receiver-family eligibility does not establish compatibility with an arbitrary mouse, availability of pairing software, or which receiver is included in a US package. Check your exact host and package before purchase.
  • K780 connectivity and absence of backlighting come from official family specifications; no region-specific key-layout claim is made.

Questions shoppers ask

What should I check if my existing receiver just says Logitech?

Identify whether it is Unifying or Logi Bolt before treating it as reusable. The brand alone does not establish either keyboard’s receiver fit. Also check the supported pairing route for your host; this comparison does not verify current pairing-software availability.

Methodology and sources

Compared the documented wireless receiver families and presence or absence of key backlighting. Recommendations describe feature fit, with Bluetooth retained as an alternative on compatible hosts.
