MagyarComputex 2021 | AMD Radeon RX 6000M series now official, RX 6800M takes on the RTX 3080 Laptop GPU at a 145 W TGP target
AMD has finally taken wraps off its mobile GPU offerings based on the RDNA 2 architecture. Led by the Radeon RX 6800M, AMD has introduced the AMD Advantage Design Framework along with FidelityFX Super Resolution (FSR) upscaling technology with this launch. AMD said that the RDNA 2 architecture offers p to 1.5x higher performance and consumes up to 43% lower power compared to RDNA 1.
Similar to NVIDIA's Ampere Laptop GPU generation, AMD's mobile lineup does not exactly match its desktop counterparts. For instance, the RX 6800M is not a derivative of the Navi 21-based RX 6800 desktop as the name indicates but is rather based on the Navi 22-based RX 6700 XT.
AMD Radeon RX 6000M Specifications
| SKU | GPU | Compute Units and Ray Accelerators | Memory | Game Clock (MHz) | FP32 Throughput | TGP Range | Memory Interface | Infinity Cache |
|---|---|---|---|---|---|---|---|---|
| AMD Radeon RX 6800M | Navi 22 | 40 | 12 GB GDDR6 | 2,300 MHz @ 145 W | 11.8 TFLOPs | 145 W+ | 195-bit | 96 MB |
| AMD Radeon RX 6700M | Navi 22 | 36 | 10 GB GDDR6 | 2,300 MHz @ 135 W | 10.6 TFLOPs | 80-135 W | 160-bit | 80 MB |
| AMD Radeon RX 6600M | Navi 23 | 28 | 8 GB GDDR6 | 2,177 MHz @ 100 W | 7.8 TFLOPs | 50-100 W | 128-bit | 32 MB |
AMD Radeon RX 6800M vs. NVIDIA GeForce RTX 3070 and RTX 3080 Laptop GPUs
AMD is primarily pitching the Radeon RX 6800M towards 1440p mobile gamers. The company said that the RX 6800M can potentially offer up to 1.7x performance uplift over a last gen RTX 2070-powered notebook. The RX 6800M was also shown to to be on par or often leading the NVIDIA GeForce RTX 3080 Laptop GPU. As always these are manufacturer numbers, so they shouldn't be taken directly at face value.
AMD did indicate that the laptops used for the RTX 3070 and RTX 3080 comparisons were the Asus ROG Strix Scar 15 G533QS and the Asus ROG Strix Scar 15 G513QR, respectively, which means that both the NVIDIA cards were running at maximum TGP of 145 W.
AMD Radeon RX 6700M — Targeting 100 fps at 1440p High
While the RX 6800M and RX 6600M are shipping now in gaming laptops, AMD hasn't announced an exact date shipping for the RX 6700M. That being said, the RX 6700M is made to target 1440p gamers desiring a 100 fps gaming experience. With 36 compute units and a somewhat cut-down 160-bit 10 GB memory, the RX 6700M can offer a good deal of the RX 6800M's performance, at least at the maximum TGP.
Unlike the RX 6800M, which is likely to be seen in notebooks with 145 W to 165 W designs, the RX 6700M can be configured by OEMs between 80 W and 135 W. This broad TGP range theoretically makes it ideal for a majority of high-end gaming laptops. This also means that the lower TGP variants are likely to be better suited for high fps 1080p rather than 1440p gaming.
AMD Radeon RX 6600M — Mainstream 1080p gaming
Finally, we have the Radeon RX 6600M with 28 compute units and 8 GB GDDR6 VRAM designed for the mainstream mobile 1080p gamers. AMD said that the RX 6600M can deliver 100 fps at 1080p in a vast majority of today's titles. The RX 6600M is meant to take on the NVIDIA RTX 3060 Laptop GPU and, according to AMD's numbers, seems to put up a very good fight.
AMD Advantage Design Framework
Alongside the new RX 6000M mobile GPUs, AMD is also introducing the AMD Advantage Design Framework for gaming laptops. Basically, AMD Advantage laptops feature Radeon RX 6000M graphics, Ryzen 5000 APUs, Smart Access Memory, SmartShift, FreeSync Premium-certified displays, fast NVMe storage, and other optimal characteristics such as power and acoustics.
The company said that AMD Advantage laptops are designed to deliver 100 fps in today's AAA games, 10 hours+ video playback, 144 Hz+ refresh rate 300-nit+ displays, and custom-tuned thermals.
Laptops powered by the AMD Radeon RX 6000M series will be available early June starting with the Asus ROG Strix G15 Advantage Edition powered by the Ryzen 9 5900HX and the Radeon RX 6800M. The HP Omen 16 is another AMD Advantage notebook that will be available soon powered by the Ryzen 9 5900HX and the Radeon RX 6600M.
