The Galaxy Book4 Ultra made available to us by Samsung features an Intel Core Ultra 9 185H processor accompanied by 32 GB of RAM and an 80 W Nvidia GeForce RTX 4070 graphics card, or 20 W more than the Book3 Ultra.
The Core Ultra 9 185H features Meteor Lake architecture. It is strictly identical to the Core Ultra 7 155H that we have tested numerous times, except that the power envelope goes from 28 to 45 W and the maximum frequency from 4.8 to 5.1 GHz.
With its Core Ultra 9 185H, the Samsung Galaxy Book4 Ultra obtains a performance index of 159 compared to 157 for the Galaxy Book3 Ultra. The HP Transcend 14, equipped with the same processor, obtains an index of 182, but it must be recognized that the ventilation of the HP is much more present. The Book4 Ultra thus remains less efficient than its great rival, Apple’s MacBook Pro in M2 Pro (168).
Thanks to the presence of a GeForce RTX 4070, the Samsung Galaxy Book4 Ultra can drastically reduce rendering times on content creation software. For example, our scene in Blender is rendered four times faster on the GPU than on the CPU. As for the increase in TGP from 60 W to 80 W compared to the Book3 Ultra, it reduces processing times on our three software programs, requiring 15% of the GPU.
With its GeForce RTX 4070 capped at 80 W, the Book4 Ultra can also launch recent games without difficulty. For example, it is possible to achieve 70 fps in Assassin’s Creed Valhallaand switching to Turbo mode of the cooling system saves a few additional i/s.
A word about the SSD which is particularly fast with 6.4 GB/s reading and 4.9 GB/s writing. Excellent performance supported by good endurance, since we did not notice any slowdown during the transfer of our test software and our video rushes.
