Xiaomi Black Shark 4

  • Extremely fast 120W wired charging
  • More affordable price point
  • Proven Snapdragon 870 performance

  • Significantly dimmer display
  • Less powerful chipset compared to the GT 8 Pro
  • Limited charging versatility

Realme GT 8 Pro

  • Superior Snapdragon 8 Elite Gen 5 performance
  • Incredibly bright display (2262 nits)
  • Versatile charging options (wired, wireless, reverse)

  • Higher price tag
  • Slightly slower endurance rating than Black Shark 4

Display Comparison

The Realme GT 8 Pro’s display is a standout feature, boasting a measured peak brightness of 2262 nits, dwarfing the Black Shark 4’s 694 nits. This difference translates to significantly better visibility in direct sunlight. While both displays offer an infinite (nominal) contrast ratio, the GT 8 Pro’s superior brightness makes it the clear winner for outdoor use. The Black Shark 4’s display, while adequate, lacks the vibrancy and clarity of the GT 8 Pro’s panel. We lack PWM frequency data for both, but the brightness difference is the dominant factor.

Camera Comparison

Both phones list 'Photo / Video' capabilities, but lack specific details. Given the market positioning, we can infer the GT 8 Pro likely features a more sophisticated camera system. The Black Shark 4 prioritizes gaming, so its camera is likely a secondary consideration. Without sensor size or aperture information, a detailed comparison is impossible. However, the GT 8 Pro’s higher price point suggests a greater investment in camera technology, potentially including features like optical image stabilization (OIS).

Performance

The core difference lies in the chipsets. The Realme GT 8 Pro’s Snapdragon 8 Elite Gen 5 (3nm) represents a generational leap over the Black Shark 4’s Snapdragon 870 (7nm). The GT 8 Pro’s octa-core CPU, with its 2x4.6 GHz Oryon V3 Phoenix L cores and 6x3.62 GHz Oryon V3 Phoenix M cores, delivers significantly higher peak performance than the Black Shark 4’s 1x3.2 GHz Kryo 585, 3x2.42 GHz Kryo 585, and 4x1.80 GHz Kryo 585 configuration. The 3nm process node of the Snapdragon 8 Elite Gen 5 also contributes to improved thermal efficiency, potentially reducing throttling during extended gaming sessions. While the Black Shark 4’s 870 is still a capable performer, the GT 8 Pro offers a demonstrably smoother and more responsive experience.

Battery Life

The Realme GT 8 Pro offers a more comprehensive charging solution. While both support 120W wired charging, the GT 8 Pro adds 120W UFCS, 14.4W PD, 55W PPS, 14.4W QC, and even 50W wireless charging with reverse wired/wireless capabilities. The GT 8 Pro reaches 50% charge in 15 minutes and 100% in 43 minutes, while the Black Shark 4 achieves 100% in 17 minutes. Despite the Black Shark 4’s slightly faster initial charge, the GT 8 Pro’s versatility and wireless charging options are significant advantages. Endurance testing shows the Black Shark 4 at 96 hours versus the GT 8 Pro’s 60:32h, but the GT 8 Pro’s active use score of 20:24h suggests more efficient power management under load, and a reported 1100 charge cycles.

Buying Guide

Buy the Xiaomi Black Shark 4 if you need a capable gaming phone at a more accessible price point, and prioritize extremely fast 120W charging. It's ideal for users who enjoy mobile gaming but don't demand the absolute highest frame rates or cutting-edge features. Buy the Realme GT 8 Pro if you prefer uncompromising performance, a significantly brighter display, and a more versatile charging ecosystem, including wireless options. This phone is geared towards enthusiasts who want the best possible mobile gaming experience and are willing to pay a premium.

Frequently Asked Questions

❓ Does the Snapdragon 8 Elite Gen 5 in the Realme GT 8 Pro get noticeably hotter than the Snapdragon 870 in the Black Shark 4 during prolonged gaming?
While the Snapdragon 8 Elite Gen 5 is more powerful, its 3nm process node is designed for improved thermal efficiency. However, increased performance *always* generates more heat. The GT 8 Pro likely has a more sophisticated cooling system to manage this, but sustained, demanding gaming will still result in some heat buildup. The Black Shark 4, with its less powerful chipset, will generally run cooler, but may experience more performance throttling under heavy load.
❓ How does the 120W charging on the Realme GT 8 Pro compare to the Black Shark 4 in real-world usage, considering the different charging protocols?
Both phones offer incredibly fast wired charging, but the GT 8 Pro’s support for multiple protocols (UFCS, PD, PPS, QC) provides greater compatibility with a wider range of chargers. While the Black Shark 4 reaches 100% slightly faster, the GT 8 Pro’s wireless charging and reverse charging capabilities offer added convenience. The GT 8 Pro’s charging ecosystem is simply more versatile.
❓ Is the difference in display brightness between the two phones noticeable in everyday use, or only in direct sunlight?
The difference is noticeable even in indoor environments. The GT 8 Pro’s 2262 nits peak brightness results in a significantly more vibrant and punchy image, with better contrast and color accuracy. While the Black Shark 4’s display is adequate, the GT 8 Pro offers a superior viewing experience in all lighting conditions.
