The Intel Xe Graphics G7 (Tiger-Lake U GPU with 96 EUs) is a integrated graphics card in the high end Tiger-Lake U CPUs (15 - 28 Watt). It is using the new Xe architecture (Gen12) and was introduced in September 2020. The GPU clocks with a base clock speed (guaranteed) of 400 MHz in all CPUs and can boost up to 1340 MHz (i7-1185G7). The slowest variant offers only 1100 MHz boost (i5-1130G7, 12 Watt TDP).
The performance depends on the TDP settings of the laptop and the used cooling. First informations show that the chip can be configured at 12 and 28 Watt TDP default (as the Ice Lake-U chips) and the performance should be around a dedicated GeForce MX350 in 3DMark benchmarks. For gaming we are expecting a bit worse performance due to the missing dedicated graphics memory and driver support. Many games e.g. had problems when testing the various laptops (e.g. Horizon Zero Dawn or Cyberpunk 2077 did not start or were crashing - see list below). Less demanding games like the Mass Effect Legendary Edition ran in medium settings fine. Compared to the older Ice Lake Iris Plus G7 GPU, the new Tiger Lake GPU should be approximately twice as fast. Therefore, the iGPU is still only for lowest graphical settings and low resolutions in demanding games.
The Tiger Lake SoCs and therefore the integrated GPU are manufactured in the modern 10nm+ (10nm SuperFin) process (improved 10nm process) at Intel and therefore should offer a very good efficiency.
The Nvidia GeForce MX330 is a dedicated entry-level mobile graphics card for laptops. It was released in February 2020 and is basically a renamed Geforce MX250 / GeForce MX150 / desktop GeForce GT 1030. It uses the same GP108 chip as the MX250 (GP108-655-A1 e.g.). It offers the same 384 CUDA cores as the MX250 and MX150 and also the clock speeds only increased slightly (+12 MHz Boost = 0.8% for the 25 Watt version). The dedicated GDDR5 graphics memory is connected via a 64 Bit memory bus and clocked at 3500 MHz (7000 MHz effective) leading to maximal bandwidth of 56 GB/s. Again there is a 25 Watt and slower 12 Watt (low power) variant.
In Nvidia drivers the GeForce MX330 appeared with the hardware ID 1D16.
The GP108 chip is manufactured in a 16 nm FinFET process and offers a number of new features, including support for DisplayPort 1.4 (ready), HDMI 2.0b, HDR and improved H.265 video de- and encoding (PlayReady 3.0). 4K HDR with Netflix however won't run due to the minimum 3 GB graphics memory that is required. Compared to the bigger Pascal chips, the small GP108 does not support Simultaneous Multi-Projection (SMP) for VR and G-Sync. A full list of improvements and the new Pascal desktop GPUs is available in our dedicated Pascal architecture article.
The performance of the GeForce MX330 should be identical to the MX150 and MX250 of previous years. See our GeForce MX250 page for gaming benchmarks. Nvidia states on the product page that the MX330 offers 2x of the performance of a Intel Iris Plus Graphics G7 in an i7-1065G7 (vs 2.5x of the MX350). Therefore, very demanding games like Red Dead Redemption 2 will not run smoothly, older and less demanding games like Fifa 20 or Farming Simulator 19 however should run fine in medium settings (see below for our benchmark results with different laptops). The low power version (see below) will be clearly slower however.
There is a low power version N17S-LP with a TGP of 12 Watt (up 2 Watt from 10 Watt of the LP MX250) and a "normal" 25 Watt N17S-G3. The performance of both variants should clearly differ. The low power variant offers relatively slow clock rates of 746 - 936 MHz (base - Turbo), where the 25 Watt G3 variant is clocked at 1531 - 1594 (similar to the MX250 and +70% boost clock versus the LP variant).
