AMD has unveiled the first mobile variants of its RX 7000 GPUs at CES 2023.
The first mobile chips on the new RDNA 3 architecture were part of AMD’s extensive CES 2023 presentation. Just like competitor Nvidia, AMD unveiled a scion of laptop GPUs around the tech fair, although AMD does this less widely. For the time being, the mobile RDNA 3 range is limited to four GPUs, which according to their denominators mainly serve the middle segment.
The four laptop chips can be divided into two different RX 7600M GPUs, aimed at 1080p games at high frame rates and two RX 7000S GPUs for thinner and light notebooks. The four GPUs share a number of specifications, such as the Navi 33 chipset as a base (204 square millimeters at 5 nm), 8 GB of GDDR6 memory and an Infinity Cache of 32 MB.
AMD’s Radeon RX 7600M XT is currently the fastest mobile RDNA 3 GPU, with 32 computing units and 2048 shader processors. According to AMD, this laptop model should be able to compete with the desktop version of Nvidia’s GeForce RTX 3060, also with 12 GB of video memory. It is striking that AMD’s heaviest laptop chip draws a maximum of 120 watts, where the RTX 3060 manages with 170 watts.
AMD benchmarks show that the RX 7600M XT achieves up to 40 frames per second more than the RTX 3060 in 1080p games. The biggest lead can be found in games such as The Witcher 3, Hitman 3 and Borderlands 3; in PUBG: Battlegrounds, AMD admits that the RTX 3060 (12 GB) is still slightly faster than the new laptop GPU.
The non-XT model of the RX 7600M and the two S-GPUs each make up their own slightly weaker tweaks of the Navi 33 base. The GPUs all come with lower (maximum) power consumption, but still promise higher frame rates in 1080p scenarios.
For example, the RX 7700S would average 147 frames per second in Death Stranding and 142 fps in Shadow of the Tomb Raider. Compared to the previous RX 6700S (as well as with 8 GB GDDR6), the RX 7700S offers up to 30 percent better performance.
Aside from performance in games, each of the mobile RX 7000 GPUs also come standard with AV1 encoding and decoding, just like their larger RX 7900 desktop brethren.
In addition to the first four mobile RDNA 3 GPUs, AMD is also expanding the RX 6000 range (RDNA 2). The RX 6550M, RX 6550S and RX 6450M each form a new mobile GPU based on the Navi 24 chipset with 4 GB of GDDR6 memory. The new range mainly enriches the lower segment of mobile GPUs
