the german portal ComputerBase just announced its first test of an AMD Radeon RX 7600S, GPU for low consumption notebooks equipped in an ASUS TUF Gaming A16. The novelty proved to be promising even in the face of energy limitations, managing to almost tie with an Nvidia GeForce RTX 4060 Mobile. That said, the bad news is that, even with the new architecture, the red team’s solution still suffers when using ray tracing, being significantly inferior when the advanced lighting effect is enabled.
Equipped with the Navi 33 chip, based on the new RDNA 3 microarchitecture, the Radeon RX 7600S has 28 Computational Units (CUs), totaling 1,792 cores and 28 Ray Accelerators for Ray Tracing. The solution also features 8 GB of GDDR6 VRAM with a speed of 16 Gbps, in a 128-bit interface, to deliver a bandwidth of 256 GB/s. To boost this transfer rate, there is 32 MB of Infinity Cache.
The most curious point is consumption: AMD claims that the component can reach 75 W, but the TUF Gaming A16 promotional materials point to a limit of 120 W. ComputerBase found an average of 80 W, with peaks of 95 W. Regardless, the important thing is the recorded performance, which is quite promising — on average, the mid-range GPU of the red team is only 6% inferior to the RTX 4060 when the Nvidia chip it is also set at 80 W.
When receiving more energy (115 W, with Dynamic Boost that pushes the total to 140 W), the representative of the GeForce RTX family goes further and opens up a significant advantage of 23%. Even so, the results show that the Radeon RX 7000 line for laptops can be quite competitive, especially in the lower consumption ranges. Furthermore, it is possible that the RX 7600M XT, which exceeds 100 W consumption, will eliminate this difference between rivals.
Unfortunately, when it comes to Ray Tracing, AMD is left behind, and by a big difference — the new Radeon would deliver half the performance of the RTX 4060 when the feature is enabled. Although consumption has an impact in this scenario, since the 80 W model of the GeForce family was not tested with the technology, the site believes that the RDNA 3 architecture is still a limitation, made worse by the low capacity VRAM.
According to the team, the new RX 7000 need more memory than the RTX 4000 (already limited by the capacity they have offered) to deliver similar performance, the main bottleneck of the RX 7600S in this case. Similar results had already been found by other analysts, such as the channel Jarrod’s Techbut this is the first time we’ve seen a more complete comparison done with Nvidia’s direct next-gen rival.
At the moment, only the ASUS TUF Gaming A16 seems to be available with the solution, with a suggested price starting at US$ 1,100 (~R$ 5,600) in the evaluated version, with a Ryzen 7 7735HS CPU. There is no forecast for the debut of this model in Brazil and, due to history, we will hardly see notebooks with Radeon GPUs around here.
