AMD Brings The Quad-Attack With Radeon RX 7000 ‘RDNA 3’ Mobility GPUs, Up to 32 Compute Units
AMD has introduced not one but four brand new Radeon RX 7000 Mobility GPUs for laptops that are based on the latest RDNA 3 core architecture. The latest SKUs include the Radeon RX 7600M XT, Radeon RX 7600M, Radeon RX 7700S, and the Radeon RX 7600S. For those wondering what these SKUs are made up of, the chips feature the brand new Navi 33 GPU core which has a die size of 204mm2 and is based on the 6nm process node as opposed to the Navi 31 GPUs which utilizes the TSMC 5nm process node for the GPU die. Some of the key features of the lineup include:
AMD RDNA 3 Architecture – New compute units share resources between rendering, AI, and raytracing to make the most effective use of each transistor for fast, efficient performance. Dedicated AI and Raytracing Acceleration – New AI accelerators and second-generation raytracing accelerators deliver incredible performance while maximizing image quality. High-Refresh Gaming – The new GPUs are designed to deliver maximum horsepower compared to competitive products for a fluid, high-refresh-rate mobile gaming experience in the latest AAA and esports games. AMD Radiance Display Engine – Provides 12 bit-per-channel color for up to 68 billion colors and higher refresh rate displays compared to AMD RDNA 2 architecture and includes support for DisplayPort 2.1. AV1 Encoding – Unlocks new multimedia experiences with full AV1 encode support, designed for ultra-high definition resolutions, wide color gamut, and HDR enhancements. AMD FidelityFX™ Super Resolution technology (FSR) – Now available and upcoming in 230 games, FSR boosts framerates in supported games while delivering incredible image quality.
Starting with the specifications, we first have the Radeon RX 7600M XT and the Radeon RX 7700S, both of which feature 32 Compute Units with 2048 shader processors, 8 GB of GDDR6 memory at 18 Gbps, and a 128-bit bus interface. Both GPUs are stacked with 32 MB of Infinity cache. These chips are rated to operate between 75W and 120W. Then we have the other two SKUs, the Radeon RX 7600M and the Radeon RX 7600S which come with 28 Compute Units or 1792 shader processors, retaining the 8 GB 128-bit memory config but with slower 16 Gbps GDDR6 dies. These chips also feature the same 32 MB of Infinity Cache. All GPUs feature AV1 Encode & Decode along with the latest Smart Technologies from the Radeon team such as SmartShift and the various SmartAccess suite (Memory/Graphics/Storage/Video). As for performance comparisons, AMD is targeting its Radeon RX 7600M XT graphics card against the GeForce RTX 3060 12 GB which has already been replaced by the new RTX 4060 Mobility GPUs. The other RX 7000 Mobility GPUs should fall under the RX 7600M XT since it is the top spec so far but AMD will be unveiling higher-end Navi 32 variants for laptops in the near future or soon after they come to the desktop platform. AMD says that the AMD Radeon RX 7000 RDNA 3 Mobility GPUs can deliver up to 30% faster transcoding performance, 60% more battery life (During gaming), and 33% higher gaming FPS (Forza Horizon 5). A new feature known as SmartShift RSR is also coming to these laptops that allows upscaling technology to be decoupled from the GPU, adding more gaming performance. This will be launching in the first half of 2023 with the GPUs rolling out in various laptops by the beginning of February.
