    RTX 5090 Laptop GPU Boosts Performance with 250W TGP

    Key Takeaways

    1. GizmoSlipTech enhanced the RTX 5090 laptop performance by overriding Nvidia’s 175 Watt power limit through a shunt modification.
    2. The shunt mod allows the GPU to draw up to 250 Watts, surpassing the previous 225 Watt limit used by others.
    3. A modified BIOS with the correct Voltage-Frequency curve and a minor undervolt is necessary in addition to the shunt mod.
    4. The Eluktronics Hydroc 16 G2 laptop achieved a 41% performance boost in 3DMark after the modifications, with a peak clock speed of 2.7 GHz.
    5. Gaming performance gains from the shunt-modified RTX 5090 ranged from 3.83% to 29.7%, indicating the potential for desktop-like performance in laptops.

    YouTuber GizmoSlipTech has successfully enhanced the performance of their RTX 5090 laptop by manually overriding the power restrictions imposed by Nvidia. The RTX 50 series, along with its predecessors, has traditionally been limited to 175 Watts due to thermal issues, which is a logical limit for a laptop. To bypass this power restriction, a shunt modification is needed. This process involves changing a particular resistor on the motherboard, enabling the GPU to draw additional power—up to an impressive 250 Watts.

    Bypassing Limits

    This new power draw surpasses the 225 Watt shunt mod previously utilized by another Reddit user. Shunt mods are commonly employed by overclockers to bypass power constraints on desktop graphics cards. However, merely applying a shunt mod is not enough; a modified BIOS featuring the right Voltage-Frequency (V-F) curve, along with a minor undervolt, is also necessary.

    Performance Gains

    The laptop used for this experiment was the Eluktronics Hydroc 16 G2, which comes equipped with an Intel Core Ultra 9 275HX processor, 48 GB of DDR5-7200 RAM, and a water cooling system to ensure optimal thermal management. Once everything was set up, the RTX 5090 laptop achieved a remarkable 41% performance boost in the 3DMark Steel Nomad test, which heavily stresses the GPU. The GPU was able to reach a peak clock speed of 2.7 GHz, which is a significant 700 MHz increase over its standard boost clock of 2.0 GHz. As anticipated, the additional power resulted in a rise in temperature.

    Gaming Performance

    In gaming benchmarks, the results were not as striking, with the shunt-modified RTX 5090 showing performance gains ranging from 3.83% to 29.7%. Even so, this demonstrates that laptop GPUs often face limitations due to insufficient power and confirms the potential for achieving desktop-like performance in a portable format.

  • RTX 50 Series Laptop GPUs Boost TGP After Nvidia Fix

    RTX 50 Series Laptop GPUs Boost TGP After Nvidia Fix

    Key Takeaways

    1. RTX 50 series laptops initially struggled to reach their maximum total graphics power (TGP), leading to disappointing performance compared to earlier models.
    2. There were reports of missing ROPs in certain RTX 50 series laptop models, contributing to performance issues.
    3. Nvidia released a driver update (GeForce GRD 576.52) on May 19, which addressed the TGP limitations in the RTX 50 series.
    4. The driver update resulted in minor performance improvements, including an additional 10W and a 50 MHz boost in clock speed for the RTX 5080.
    5. Despite the performance gains from the driver update, Nvidia did not publicly emphasize the issue, opting to keep it low-profile.

    Soon after reviewers began testing the RTX 50 series laptops, it became clear that these GPUs were struggling to hit their maximum total graphics power (TGP). This led to disappointing performance, with earlier generation laptops outperforming the new RTX 50 series. Thankfully, Nvidia has quietly resolved this issue with a driver update released on May 19.

    Performance Problems on Arrival

    Despite the delayed launch and limited communication from Nvidia regarding the RTX 50 series laptops, there were significant performance issues upon their arrival. Reports indicated that certain models had missing ROPs, a problem that also affected some desktop GPUs. Furthermore, reviewers noted that the laptop GPUs failed to achieve their expected 175W TGP. Although TGP can vary among different GPUs, this seemed to be a common problem with the RTX 50 series, resulting in lackluster performance and further disappointment regarding the series’ launch.

    Driver Update Brings Improvements

    Fortunately, the GeForce GRD 576.52 driver, released on May 19, appears to have resolved these concerns. Within the general bugs section, one fix noted is “[Notebook] GeForce RTX 50 series TGP limit may be clipped earlier.” According to YouTuber GizmoSlipTech, this issue has indeed been addressed. In a brief video comparing performance in Witcher 3, the RTX 5080 laptop GPU managed to achieve an additional 10W and a 50 MHz boost in clock speed following the driver update.

    Minor Gains in Gaming Performance

    While the increase in FPS during gameplay wasn’t groundbreaking, it was encouraging to see that the GPU could reach, or at least come closer to, its full capabilities. Nvidia did not publicly highlight this update, seemingly preferring to keep the issue under wraps, which is not surprising given the circumstances.
