Dream Machines RX4090-17PL25 test – Top notebook with NVIDIA GeForce RTX 4090 Laptop GPU and Intel Core i9-13900HX

Some time ago we had the opportunity to test one of the latest notebooks from Dream Machines. This model was equipped with the NVIDIA GeForce RTX 4070 graphics chip, which had extremely uneven performance. The company, however, also offers much stronger proposals and today we will focus on the flagship notebook, which surprisingly does not cost much more than the aforementioned model with the GeForce RTX 4070. Dream Machines RX4090-17PL25, because we are talking about it, uses the most powerful graphics generation of Ada Lovelace for laptops, while remaining by far the cheapest device tested in our new test procedure so far. A much lower price does not translate into noticeably worse performance in this case. If we mainly look at performance, the Dream Machines RX4090-17PL25 really has some strong bargaining chips that are worth taking an interest in.

NVIDIA GeForce RTX 4090 Laptop GPU is the flagship graphics chip of the current generation for portable computers. However, it has nothing to do with the desktop GeForce RTX 4090 card. Instead, it was decided to keep the specification identical to the desktop GeForce RTX 4080. So we get an almost full AD103 core with 9728 CUDA FP32 cores, 76 3rd generation RT cores and 304 Tensor 4 cores generation. The Ada Lovelace architecture itself is the same for desktops as it is for laptops. Thus, we get e.g. more powerful CUDA cores, rebuilt RT cores for ray tracing acceleration, and new Tensor cores with Frame Generator and Optical Flow Accelerator support. The whole thing is seasoned with 16 GB of GDDR6 memory on a 256-bit bus. For testing, we received the Dream Machines RX4090-17PL25 laptop, which is the most powerful model in the company’s offer and in which the power of the NVIDIA GeForce RTX 4090 Laptop GPU is a maximum of 175 W. The whole was developed in a completely new and much more advanced TSMC 4N lithography, which allowed us to pack over 45 billion transistors in a relatively small area of ​​the AD103 graphics core. This allowed for a nearly 3-fold increase in the packing density of the transistors relative to the GA103 core in the Ampere architecture and the Samsung 8 nm process.

Dream Machines RX4090-17PL25 is the company’s flagship notebook, which is equipped with an Intel Core i9-13900HX processor and NVIDIA GeForce RTX 4090 Laptop GPU graphics.

In the case of the Ada Lovelace architecture, one cannot forget about the support for the DLSS 3 technique, the most important novelty of which is the Frame Generation function, where a third one is placed between two already rendered frames, created with the help of AI and Tensor cores, and for the preparation of which, among others, . motion vectors from two adjacent frames and the Optical Flow Accelerator engine. With DLSS 3, performance can be significantly increased without significantly affecting image quality. In laptops, where the screens have a much smaller diagonal and thus denser packing of pixels, possible differences in the image will be even less noticeable compared to much larger monitors. The list of supported games is growing regularly, and the tests I have been conducting in recent days confirm that it will be a real “gamechanger” for the notebook market, to which the competition currently has no answer.

The tested Dream Machines RX4090-17PL25 is one of the most powerful models offered by the Polish company. In addition to the NVIDIA GeForce RTX 4090 Laptop GPU, on board we will also find a 24-core and 32-thread Intel Core i9-13900HX processor from the Raptor Lake-HX family (its Turbo clock reaches a maximum of 5.4 GHz), 16 GB of DDR5 RAM 4800 MHz and 1 TB PCIe 3.0 x4 NVMe SSD. On board we will also find a good quality QHD screen (2560 x 1440 pixels) with a 16: 9 aspect ratio and with nearly 100% coverage of the DCI-P3 color space. The tested version has Windows 11 Home 64-bit 22H2 installed, and the total amount presented configuration is PLN 15,429.
