Quick answer

Choose the ATTACK SHARK RS3 ULTRA if you want flagship sensor precision and a carbon fiber shell; choose the ATTACK SHARK X8 ULTRA if you want an 8KHz wireless mouse at a lower price and don't need the PAW3955MAX sensor.

Sensor and processing: precision vs polling rate

The RS3 ULTRA uses the PixArt PAW3955MAX sensor with 1–52,000 DPI, 850 IPS tracking, and 75G acceleration, paired with a Nordic 54L15 MCU for up to 20,000 FPS tracking and 0.168ms response time. That combination targets esports players who need fine control at high speeds.

The X8 ULTRA is defined by its 8KHz wireless polling rate. Higher polling means more position updates per second, which can feel smoother in fast-paced games, but it also places more demand on your PC and can reduce battery life. The supplied catalog does not list the X8 ULTRA's sensor model or DPI range, so treat its tracking specifications as unconfirmed.

Build and bundle: carbon fiber vs color options

The RS3 ULTRA's carbon fiber construction is a distinct material choice that may appeal if you prefer a stiffer, lightweight feel. The X8 ULTRA comes in Black or White, making it easier to match a desk setup, but no shell material is specified.

Both mice include the C06 Ultra LED cable, so you get the same charging and wired-use accessory regardless of model. Neither product page lists weight, grip width, or button count in the supplied facts, so check those details separately if they are critical for your hand size.

Key trade-offs

  • Precision vs polling rate: The RS3 ULTRA gives you a known flagship sensor with 1 DPI adjustment and 850 IPS; the X8 ULTRA gives you 8KHz polling but no published sensor model. If you value verified tracking specs, pick the RS3 ULTRA. Check whether your games and PC can benefit from 8KHz before choosing the X8 ULTRA.
  • Material and color: The RS3 ULTRA uses a carbon fiber shell; the X8 ULTRA comes in Black or White. Choose based on whether you prioritize a specific material feel or color matching.
  • Budget and features: The X8 ULTRA costs less and still includes the C06 Ultra cable, while the RS3 ULTRA carries a higher price for its sensor and MCU. Decide if the PAW3955MAX and carbon fiber are worth the extra spend for your playstyle. Set a hard budget before comparing, so you don't pay for specs you won't use.
