The fastest GeForce RTX 4090 & RTX 4080 GPUs from NVIDIA are now available in gaming laptops, and early benchmarks indicate astounding performance improvements.
The NVIDIA GeForce RTX 4090 and RTX 4080 are the most powerful graphics processing units (GPUs) for gaming laptops. They provide the greatest increase in performance across generations and the highest levels of efficiency. In addition, these laptop CPUs include new and advanced capabilities such as DLSS 3, which provides a performance gain of up to four times the native resolution. So, let’s find out what these chips are all about.
NVIDIA GeForce RTX 4090 16 GB Mobile GPU
The flagship GeForce RTX 4090 includes the NVIDIA AD103 GPU core with a total of 76 SMs or 9728 CUDA cores, which is identical to the desktop-class RTX 4080 and offers TGP options ranging from 150W to 175W (+25W Dynamic Boost). The 150W TGP aim will be configured with a clock frequency range of 1590 MHz Base and 2040 MHz Boost. In addition, there is a 25W Dynamic Boost that enables even higher boost clocks.
NVIDIA GeForce RTX 4080 12 GB Laptop GPU
The NVIDIA GeForce RTX 4080 16 GB variant provides a total of 58 SMs with 7424 cores and a memory configuration that comprises 12 GB of GDDR6 memory with a 192-bit interface. The GPU is an Ada AD104 design, which is the same chip as the GeForce RTX 4070 Ti Desktop graphics card, but in a scaled-down form. In reality, the GeForce RTX 4080 GPU for laptops has around 24 per cent fewer cores than the desktop version.
The GPU features a comparable TGP range, but the adopts AD104 GPU core. The GPU’s TGP range will be between 150W and 175W, with a Base clock of 1.86 GHz and a Boost clock of 2.40 GHz for the 150W objective. In addition, the RTX 4080 will gain an additional 25W of Dynamic Boost power.
NVIDIA GeForce RTX 40 Ada Laptop GPUs
The performance of the NVIDIA GeForce RTX 4090 Laptop GPU first, the mobile chip, was displayed on a Zero Thunderobot system evaluated by MyDrivers. It can reach up to 170W of power during testing while maintaining GPU core temperatures below 80C. The memory operates at a slightly higher temperature of 85C, but it is still considerably below its thermal limit.
The GPU achieves 19,387 points in the 3DMark Time Spy benchmark and 10,203 points in the 3DMark Time Spy Extreme benchmark. The similar GPU obtains 26,100 points in 3DMark Fire Strike Extreme and 13,371 points in 3DMark Fire Strike Ultra. This represents a performance boost of up to 60% compared to the 3080 Ti Laptop GPU, which was the flagship product of the previous generation.
However, with better designs, such as the ASUS ROG STRIX SCAR 17 reviewed by ITHome, the GPU can achieve far higher scores. In the Furmark stress test, the GPU on the SCAR 17 operates at the same 175W power restriction but at significantly lower temperatures of 70C. This GPU earned 22,044 points in 3DMark Time Spy and 26,526 points in 3DMark Fire Strike Extreme, a 13% improvement over the 4090 on the other laptop. This is comparable to the performance of a desktop RTX 4070 Ti or RTX 3090 graphics card.
PCWorld also presented its gaming testing and content creation benchmarks, demonstrating a significant performance increase over the previous generation. HardwareUnboxed reports that the NVIDIA GeForce RTX 4090 (150-175W) is 58% more powerful than the RTX 3080 Ti Laptop GPU at 4K resolution. This is a significant improvement compared to the desktop-class RTX 4090 graphics card. In the meantime, Jarrod’sTech examined a Lenovo system equipped with an RTX 4080 laptop and observed an average performance increase of >25% compared to the RTX 3080 Ti laptop at 4K resolution.
The only drawback is that one of these huge machines will cost you several thousand dollars. However, Jarrod’sTech provides this intriguing graph comparing the cost per frame, and it appears that the new RTX 40 Ada laptop provides a little higher performance-to-cost ratio. For instance, the least expensive RTX 4090 laptop available at Newegg costs $3,499 US (AORUS 17X). in comparison, the lowest-priced RTX 4080 laptop on Newegg costs $2,299, (AORUS 17H).
