Corsair K70 CORE vs Logitech MX Keys S: Keys and Desk Workflow

Choose K70 CORE for linear mechanical keys and a physical dial at a wired desk. Choose MX Keys S for its low-profile scissor-key design and switching among paired computers. Make the connection decision first if the keyboard must serve several machines; Corsair’s saved profiles are settings, not computer pairings.

The buying question

Do mechanical keys and a dial matter more to you than low-profile keys and built-in switching between wireless hosts?

K70 CORE combines mechanical keys and physical controls with a wired connection; MX Keys S combines low-profile scissor keys with wireless host switching and recharging.

Quick verdict

When to skip: Your desk requires both wireless computer switching and the K70 CORE’s mechanical-key/dial combination in one keyboard.
When the recommendation changes
  • The intended computer has no suitable USB-A connection for the K70 CORE.
  • You regularly switch between a work computer and a personal computer.
  • A physical dial matters less to you than the key mechanism you prefer.

The differences that matter

Key Mechanism And Physical Controls

CORSAIR K70 CORE RGB (NA, with palm rest)

Linear mechanical switches, a multifunction rotary dial and an included detachable magnetic palm rest.[4, 5]

Logitech MX Keys S (Graphite)

Low-profile design with scissor keys and media/function-key controls.[1, 3, 2]

What this changes: Choose the K70 CORE if mechanical keys and a physical dial are what you want to use. Choose MX Keys S if you prefer the low-profile scissor-key approach. These hardware differences do not prove which feels better, sounds quieter or makes you type faster.[4, 1, 3]

The better fit depends on your priorities

Connection And Multi Device Workflow

CORSAIR K70 CORE RGB (NA, with palm rest)

Wired USB Type-A connection; the setup guide specifies an available USB 3.0 or better Type-A port on a compatible device.[4, 5]

Logitech MX Keys S (Graphite)

Bluetooth or included Logi Bolt receiver; Easy-Switch selects among up to three paired computers. USB-C recharging can happen while typing.[2, 3]

What this changes: K70 CORE fits a desk where a wired connection to the working computer is acceptable. MX Keys S fits repeated switching between paired hosts without moving that keyboard connection, but adds battery charging to the routine.[5, 2]

The better fit depends on your priorities

Best for your routine

A desk centered on one wired computer and mechanical keys

Best fit: CORSAIR K70 CORE RGB (NA, with palm rest)

Based on listed features, not comparative testing.

K70 CORE combines the specified key mechanism, dial and USB-A setup. Choose it for those features, not a promised latency or gaming advantage.

One keyboard shared between work and personal computers

Best fit: Logitech MX Keys S (Graphite)

Based on listed features, not comparative testing.

MX Keys S provides paired-host channels and a key-based switch between them. Its compromise is the scissor-key design and a battery that needs recharging.

A preference for a low-profile scissor keyboard

Best fit: Logitech MX Keys S (Graphite)

Based on listed features, not comparative testing.

The documented design fits that preference even if you use only one computer. Do not buy mechanical keys merely because the K70 is marketed for gaming.

Value and trade-offs

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

Whichever costs more should earn the difference through a key mechanism, physical control or connection workflow you will actually use. A gaming label, profile count or claimed typing feel alone does not establish better value.

There is not enough verified price history for a purchase-timing recommendation. Compare current offers for these exact configurations.

Limitations

  • This comparison uses manufacturer documentation without Pickoryx hands-on testing. It does not establish gaming latency, typing speed, noise, comfort or reliability superiority.
  • The selected Corsair is full-size Black CH-910981E-NA with palm rest, not CORE TKL, TKL Wireless, SE or another K70. Current marketing and its specification table differ on the switch-generation label, so this comparison makes no version-specific switch claim.
  • The Logitech is standard US Graphite 920-011558, not the older MX Keys, a for-Mac edition or a mouse combo. Check software and operating-system requirements before relying on customization.

Questions shoppers ask

Are Corsair’s five profiles the same thing as Logitech’s three device channels?

No. K70 CORE profiles hold settings and RGB choices. MX Keys S Easy-Switch channels select paired computers. Compare them against different needs: changing keyboard behavior versus changing the computer receiving input.

Does every K70 CORE dial function start enabled?

No. Its guide lists volume, brightness and vertical scrolling as default on, with horizontal scrolling and zoom default off. Fn+F12 cycles dial modes; use the guide and iCUE settings when configuring the available modes.

Can I keep using MX Keys S while it recharges?

Yes. Logitech says typing can continue while the USB-C cable is connected for charging. Plan its keyboard connection through the documented Bluetooth or Logi Bolt setup rather than confusing charging with paired-host selection.
