Nvidia RTX 40 mobile GPUs to bring 30-50% performance uplift over previous generation

The initial 3DMark Time Spy scores of the RTX 40 series mobile GPUs have been shared online, giving us the first glimpse at the performance gains they will bring over the previous generation. Overall, performance gains seem to vary between 30-50% over their RTX 30 series counterparts.

The Time Spy scores shared by Wccftech suggest the upcoming Nvidia RTX 40 series laptop GPUs could be a worthwhile upgrade for laptop gamers. Even if these are just the results of a synthetic benchmark, it should be enough to get an idea of how the new mobile GPUs will compare against the RTX 30 series laptop GPUs. Currently, it appears sources are uncertain about the top-end RTX 40 mobile GPU, with some referring to it as an RTX 4090, while others refer to it as an RTX 4080 Ti.

Besides the scores, the data gathered by Wccftech also reveals the GPU's internal names. At the top of the chart, we see the RTX 4080 Ti (GN21-X11) outperforming the RTX 3080 Ti by 30%. The same performance uplift is seen between the RTX 3080 and the RTX 4080 (GN21-X9) and between the RTX 3060 and the RTX 4060 (GN21-X4). The performance uplift of the RTX 4070 (GN21-X6) over the RTX 3070 is more significant, hovering at 45%, whereas the biggest difference would be seen in the RTX 4050 (GN21-X2), scoring 50% higher than the RTX 3050.

Expected memory specifications for the RTX 40 series mobile lineup have also been shared, claiming the RTX 4080 Ti/4090 laptop GPU should come with 16GB and the RTX 4080 with 12GB. The RTX 4070 and 4060 likely pack the same amount of memory as their predecessors, with 8GB of VRAM. Lastly, the RTX 4050 laptop should bring 6GB of VRAM, 2GB more than the RTX 3050.

Nvidia has not officially announced its next-generation laptop GPUs yet, but the company will be holding a keynote during CES in January, so we might see the first official details revealed then.

KitGuru says: It is likely that Nvidia's new laptop GPUs will also benefit from improved ray-tracing cores, and DLSS 3 support to further enhance performance. With that in mind, these tests don't paint a complete picture, but if accurate, the results do give us some early comparisons.
