The flagship of the mobile graphics card GeForce RTX 4090 was faster than the desktop flagship of the previous generation GeForce RTX 3090 Ti in the synthetic test of 3DMark Time Spy. True, there were some changes in the configuration of the mobile graphics accelerator – a slight overclocking was performed.
One of the users of the Reddit forum boastedthat its latest gaming laptop, the Razer Blade 18, equipped with a 13th generation Intel Core processor and a GeForce RTX 4090 graphics accelerator, showed incredible levels of performance in 3DMark Time Spy after some tweaks.
According to reviews from industry media, the GeForce RTX 4090 is indeed the fastest mobile graphics card of our time, and the $4,500 Razer Blade 18 laptop in a configuration with this graphics card is described by the manufacturer as “Ideal replacement for desktop gaming PC“. There is no doubt about the first thesis.
However, as mentioned, the mobile and desktop versions of the GeForce RTX 4090 have nothing in common apart from the same name and architecture. These cards are completely different: GPU, frequencies, amount of video memory. If we draw a parallel, then the mobile GeForce RTX 4090 is closer to the desktop GeForce RTX 4080 as both use the same GPUs but with different frequencies. At the same time, the mobile flagship cannot compete with the desktop GeForce RTX 4080 either. First of all because of the lower power consumption, which stands at 175 W for the mobile flagship (including Dynamic Boost), which is of course a lot for a laptop, but not so much when it comes to the desktop segment of graphics cards.
And yet the mobile GeForce RTX 4090 made it to 22,339 points in the 3DMark Time Spy graphics test after a little fiddling with the settings. It overtook the desktop GeForce RTX 3090 Ti, which scored 21,015 points in the same test. The mobile GeForce RTX 4090 performs just below the desktop GeForce RTX 4070 Ti, which scores 23,390 in the same test but has a claimed power consumption of 250W.
To achieve this result, a Razer Blade 18 owner with a mobile GeForce RTX 4090 increased the GPU frequency by 250 MHz via the MSI Afterburner utility, but left the video memory settings unchanged. After overclocking, the cooling system of the laptop had problems with heat dissipation from the CPU and the frequency began to drop, but the cooling system coped with the mobile graphics card in the test.
