In 3DMark Time Spy, the performance of NVIDIA’s top-of-the-line GeForce RTX 4090 Laptop GPU can surpass that of the 3090 Ti desktop graphics card, making it even faster.
The Razer Blade 18, touted as “The Ultimate Desktop Replacement,” is a pricey laptop that starts at a minimum of $4500 US. However, it is equipped with NVIDIA’s top-of-the-line laptop GPU, the GeForce RTX 4090, which is currently the fastest graphics chip available for laptops. Recently, u/Kelzs, a Redditor, fine-tuned their Razer Blade 18 to maximize its performance.
It’s common knowledge that the GeForce RTX 4090 Laptop and desktop graphics card share the same name, but have distinct specifications. Although the laptop GPU has similar GPU specs to the desktop’s RTX 4080, it’s been reduced even further with lower clocks and a lower TGP target. This is typical for a laptop GPU, but the naming convention might lead one to assume that the RTX 4090 Laptop is as fast as its desktop counterpart, which, as I mentioned earlier, is not accurate.
Despite the differences in specs between the laptop and desktop versions, the NVIDIA GeForce RTX 4090 Laptop GPU is still an incredibly fast gaming solution. In fact, when compared to the tuned GeForce RTX 3090 Ti, which was NVIDIA’s fastest gaming graphics card just a year ago, the RTX 4090 comes out on top in 3DMark Time Spy. What’s particularly noteworthy is that the RTX 4090 Laptop GPU achieves this feat while consuming only a maximum of 175W TGP, while the RTX 3090 Ti can consume anywhere from 450-500W in the same benchmark test. Although the RTX 4090 Laptop GPU is a bit slower than the RTX 4070 Ti desktop graphics card, even that card only requires around 250W power.
Kelzs utilized MSI Afterburner to overclock the GPU by +250 MHz, while leaving the memory settings at default. Although the CPU was experiencing thermal throttling, the cooling for the GPU was sufficient to achieve a higher score. This demonstrates the impressive efficiency of NVIDIA’s RTX 40 GPUs for laptops, as they continue to dominate the mobile GPU market in terms of performance.
