The RTX 4090 mobile uses 16 GB GDDR6 dedicated graphics memory with a clock speed of 20 Gbps (effective). The AD103 chip offers a maximum of 10.752 shaders from which inly 9728 are used (e.g., the RTX 4080 Desktop uses 9.728) and a 256 Bit memory bus. It is based on the AD103 chip as the desktop RTX 4080 and use the Ada Lovelace architecture. The NVIDIA GeForce RTX 4090 Laptop GPU (Codename GN21-X11) is a high-end laptop GPU. NVIDIA GeForce RTX 4090 Laptop GPU ► remove from comparison The Tiger Lake SoCs and therefore the integrated GPU are manufactured in the modern 10nm+ process (improved 10nm process) at Intel and therefore should offer a very good efficiency. Therefore, the iGPU is still only for lowest graphical settings and low resolutions in demanding games. Compared to the fastest Ice Lake iGPU (Iris Plus G7), the 48 EU version in an i3 should be slightly faster. For gaming we are expecting a bit worse performance due to the missing dedicated graphics memory and driver support. First informations show that the chip can be configured at 15 and 28 Watt TDP default (as the Ice Lake-U chips) and the performance should be around a dedicated GeForce MX230 in 3DMark benchmarks. The performance depends on the TDP settings of the laptop and the used cooling. It is using the new Xe architecture (Gen12) and should be announced later in 2020.

The Intel UHD Graphics Xe Graphics G4 (Tiger-Lake U GPU with 48 EUs) is a integrated graphics card in the low end Tiger-Lake U CPUs (15 Watt, e.g.
