Razer BlackWidow V3 Mini Hyperspeed vs Corsair K70 RGB TKL: Mechanical Keyboard

After a Huntsman Tournament Edition model, Razer now offers a brand new keyboard in mini format. This is the Blackwidow v3 Mini Hyperspeed. This model is a scaled-down version of the brand’s most famous keyboard. It comes in a format equivalent to 65% of an ordinary keyboard with a numeric keypad.

This year, the manufacturer Corsair has decided to impose itself on the Esport market. After placing a K65 RGB Mini keyboard on the shelves, to say the least, unusual for the brand, Corsair is tackling a Champion Series this time. With its K70 RGB TKL model, the firm continues to break its own codes.

Razer has opted this time for a small keyboard focusing on its wireless connectivity. It, therefore, embeds, like its big brother, the Razer Blackwidow V3 Pro, a HyperSpeed ​​wireless connectivity mode. It also contains a Bluetooth connection, which turns out to be a great asset for owners of Apple products or tablets. Note that the responsiveness will be much less important than the brand’s 2.4 GHz technology in this case. This Blackwidow v3 Mini Hyperspeed can also be connected using a USB-C to USB-A cable provided in the box. With this connection to current standards, the device can be used while recharging its batteries.

Its dimensions are surprising, and therefore it does not take up much space on the desk. It, therefore, incorporates a lot of shortcuts printed on the underside of the keys. Too bad Razer didn’t think about allowing RGB to illuminate these secondary functions. The Fn key will therefore be used to activate most of the missing keys. Still, this Blackwidow v3 Mini Hyperspeed also has directional keys and 4 macro keys configured on the fly or with Razer Synapse 3.

The new Corsair K70 RGB TKL mechanical keyboard is devoid of all the interesting in-game functions. It indeed embeds many customization possibilities thanks to the iCUE software and still has several additional keys.

Out of the box, the Corsair K70 RGB TKL immediately reassures us about its manufacture. Unlike its little brother, the K65 RGB Mini, this newcomer includes a brushed aluminum chassis and tinted black. The CHERRY MX SPEED keys are directly placed on this black aluminum, which brings out the best effect of the LEDs.

In the box are also QWERTY key covers to which the brand has accustomed us for several years. They are gray and lightly textured for better finger grip. Finally, the cable used to power the keyboard is USB-A to USB-C type and detachable. Perfect for transport and interchangeable in the event of a problem.

  • Keyboard warranty: 2 years
  • Keyboard backlight: RGB
  • Switches: 100% CHERRY MX SPEED
  • Polling rate up to 8000Hz and key analysis of 4000Hz with CORSAIR AXON
  • 100% anti-ghost with rollover of the N keys (NKRO)
  • 8MB of built-in storage for up to 200 profiles
  • 32-bit ARM Cortex processor

Razer BlackWidow V3 Mini Hyperspeed- On the back is a notch with a plastic cover enclosing the USB dongle. This one is a bit special. It allows the user to connect both their keyboard and another Razer mouse to it. The list of compatible mice is not very extensive for the time being, but we imagine that the manufacturer will gradually expand it. Compatible mice are the new Orochi V2, Naga Pro, and DeathAdder V2 Pro. The keyboard can also store three Bluetooth devices in memory. This will avoid restarting the pairing each time you change your PC or tablet. Using the Fn + 1, 2, or 3 key, you can switch from one Bluetooth profile to another. Simple, right?

Who says wireless connection says powerful battery. On paper, this small device offers 200 hours of battery life. On closer inspection, this autonomy is only reached when all RGB effects are turned off. At 30% RGB brightness, we go directly down to 48 hours and 17 hours for maximum brightness.

Blackwidow v3 Mini Hyperspeed comes with Razer Yellow or Green mechanical switches. The yellow version that we tested is a silent version of Green mechanical switches. We are dealing with a very linear activation, the noise of which has been suppressed with a silicone membrane. Therefore, the responsiveness is at the top level, even if some players criticize it for this lack of click sensation.

The keyboard keys are made of two layers of durable plastic for good visibility of letters and symbols. These Doubleshot ABS keys prevent the inscriptions from fading over time and retain the original texture of the plastic as much as possible. Alas, the secondary functions of this miniature BlackWidow do not benefit from the same treatment and are well printed in white? That said, they are on the undersides of the keys and shouldn’t come into much contact with finger strikes or sweat. A view on the long term.

Corsair K70 RGB TKL- This newcomer to the Corsair range also comes with the brand’s new standards. Like the K65 RGB Mini, this Corsair K70 RGB TKL includes 8MB of internal memory for up to 50 profiles with clean RGB lighting and macros. This number can rise to 200 when one does not pay attention to these last two elements. That said, the usefulness of having so many profiles on his keyboard remains to be demonstrated because the player generally only switches a few settings.

The double-shot keys of this model give good longevity of 100 million activations. As for the CHERRY MX, SPEED tuners are formidable with a click that is not very silent, although slightly damped, but above all, an excellent activation stroke of 1.2mm. This is still inferior to Razer’s optical switches, but it is, on the other hand, perfect for pure mechanics. There is obviously the presence of anti-ghosting for simultaneous key presses, which is effective and, so to speak, essential in all games.

With the K70 RGB TKL, Corsair is truly establishing itself in the Esport market. This is, of course, a model addressed to hardcore players. Its detachable USB power cable avoids double USB-A for power and RGB effect. S is detachably aspect makes the key K70 RGB TKL very mobile. Excellent for LAN sessions with friends. In general, the keyboard says goodbye to the touchpad by consuming less space, but while retaining essential functions for gamers—a companion of choice for the competition is offered at 176 USD..


This Blackwidow v3 Mini Hyperspeed is very versatile. It benefits from this triple connection which makes it compatible with a slew of devices, and its small size makes it very mobile. It is Razer’s most successful Esport model to date and delivers top-notch performance. There is no doubt that its aesthetics will also convince many lovers of the brand, who will benefit from Razer’s latest technological advances in wireless peripherals.
