AMD announces first Radeon RX 7000 laptop GPUs based on RDNA3

AMD announces its first separate laptop GPUs based on RDNA 3. The manufacturer introduces variants with up to 32 compute units and power limits up to 120W. Laptops with the video cards will be released from February.

AMD introduces during the CES fair four different RDNA3 laptop GPUs. The Radeon RX 7600M XT is the highest positioned model of this. This GPU is aimed at 1080p gaming with high frame rates. The GPU in question has 32 compute units, for a total of 2048 stream processors. According to AMD, the video card thus delivers up to 21.4Tflops of fp32 computing power with ‘game clocks’ of up to 2.3GHz. The RX 7600M XT has power limits from 75 to 120W.

The Radeon RX 7600M is a slightly lower positioned model. This video card gets 28 cu’s, which amounts to 1792 stream processors. According to AMD, the RX 7600M delivers up to 21.4Tflops of single-precision computing power, with power limits from 50 to 90W. Both video cards are equipped with 8GB of GDDR6 memory and a 128-bit memory bus. The memory of the XT variant is slightly faster, with 18Gbit/s compared to 16Gbit/s for the non-XT GPU. Both video cards also have 32MB of Infinity Cache.

AMD also comes with two Radeon RX 7000S video cards, in the form of an RX 7700S and RX 7600S. These are virtually identical to the Radeon RX 7600M XT and RX 7600M respectively, but have lower power limits. The RX 7700S consumes a maximum of 100W, while the RX 7600S consumes a maximum of 75W.

The video cards all get the features that come with the RDNA3 architecture, such as integrated cores for AI work, improved ray tracing cores and support for hardware AV1 encoding. The GPUs also support SmartAccess Memory, also known as resizable bar, which allows a processor to access the full amount of vram at once. Previously, this was only possible with blocks of 256MB.

In addition, the video cards get SmartShift, which balances the power consumption of the CPU and GPU for better battery life. New is SmartShift RSR, which divides rendering and upscaling tasks between the CPU and GPU. Later this year, the RDNA3 GPUs will also receive support for FSR 3.0, a new version of AMD’s temporal upscaling technique that can interpolate new frames.

AMD claims that the Radeon RX 7600M XT is 18 to 39 percent faster than the previous Radeon RX 6600M. According to the GPU maker, the video card performs better than Nvidia’s RTX 3060 8GB and 12GB desktop video cards. The laptop GPU outperformed those Nvidia cards in nine games tested. There are no independently made benchmarks available yet.

These are AMD’s first lower-positioned RDNA3 video cards. The company only released its flagship RX 7900 desktop models to date. Presumably, the four new laptop video cards have a Navi 33 GPU. AMD doesn’t officially confirm this, but a recent software update in AMD’s ROCm software already confirmed that Navi 33 GPUs will get a maximum of 32 cu’s. The first laptops with the new Radeon RX 7000 video cards will appear in February, but there is no concrete release date yet.
