AMD Radeon RX 6800M Review

If you think Nvidia’s GeForce has long had a lock on desktop GPUs, it’s nothing less than Fort Knox on gaming laptops, where it simply dominates all. That could change, however, with AMD’s new RDNA2-based Radeon RX 6000 GPUs, which promise solid competition to the high-flying GeForce chips.

To find out just how well AMD’s new GPU and CPU do, we took the new Asus ROG Strix G15 Advantage Edition around the block. If you’re looking for more CPU tests, we recommend that you read our review of Intel’s 11th-gen Tiger Lake H, where we look at the same CPU used in the G15.

What’s different in the ROG Strix G15 Advantage Edition is obviously the GPU: AMD’s Radeon RX 6800M, which features 40 compute units, 12GB of GDDR6 RAM, and 96MB of Infinity Cache on a 192-bit memory interface—and finally, real competition in gaming laptops.

How we tested

For the gaming tests we confined our tests to three nicely outfitted laptops that would fall into the “performance” category of gaming laptops. They aren’t sumo-wrestler beefy, but neither are they marathon-runner stringy:

  • Gigabyte Aorus 17G with Intel 8-core Core i7-10870H, Nvidia GeForce RTX 3080 Laptop GPU with a TGP of 105 watts, and 16GB of GDDR6 RAM. The laptop also features 32GB of DDR4/2933 in dual-channel mode and a 1TB NVMe SSD, along with a 300Hz, 17.3-inch FHD screen. The laptop weighs about 6.1 pounds and is powered by a 230-watt power brick.
  • Asus ROG Strix G17 with 8-core AMD Ryzen 9 5900HX, Nvidia GeForce RTX 3080 Laptop GPU with a TGP of 130 watts, and 16GB of GDDR6 RAM. The laptop features 32GB of DDR4/3200 in dual-channel mode and a 1TB NVMe SSD, along with a 360Hz, 17.3-inch FHD screen. The laptop weighs about 6 pounds and is powered by a 240-watt power brick.
  • Asus ROG Strix G15 Advantage Edition with 8-core AMD Ryzen 9 5900HX and AMD Radeon RX 6800M with 12GB of GDDR6 RAM. The laptop also features 16GB of DDR4/3200 in dual-channel mode, and a 512GB NVMe SSD. It weighs 5 pounds and is powered by a 280-watt power brick. AMD spec’s the Radeon RX 6800M at 145+ Watts but let’s just say it clearly could use more.

Sexy doesn’t have to be thin. Despite its thick body, the ROG Strix G15 is relatively light and features eye-catching accents that can be swapped out.

Synthetic Performance

We’ll kick this off with UL’s popular synthetic 3DMark benchmark, which measures DirectX12 graphics performance. Although not an actual game, it’s a very reliable and very repeatable test. The scores also break down both the overall performance, which slightly factors in the CPU physics performance as well as pure GPU performance. For the charts below, the bars that are solid red indicate an all-AMD laptop, which is the Ryzen 9 5900HX and the Radeon RX 6800M. Bars with red and green indicate a Ryzen CPU with a Nvidia GPU, while a blue-and-green bar indicates an Intel CPU and Nvidia GPU.

The overall score for 3DMark Time Spy puts the ROG Strix G15 Advantage Edition with its all-AMD components in a pretty good spot, right between the other two laptops. That’s a solid win even if it doesn’t come out on top, since neither of the two GeForce RTX 3080 Laptops-based units are slouches.

Longer bars indicate better performance. Green indicates Nvidia components. Blue indicates Intel components. Red indicates AMD components.

Digging into pure GPU performance, we see the Radeon RX 6800M separated by just 3 percent from the 130-watt GeForce RTX 3080 Laptop GPU. With the GeForce RTX 3080 Laptop at a more relaxed 105 watts, the Radeon RX 6800M actually outpaces it by about 8.9 percent.

Ray tracing performance is the brave new world of gaming. It can greatly reduce the amount of work game developers have to do for better lighting and reflections, but it’s computationally expensive. While Nvidia has dedicated cores in its 20-series and 30-series GPUs for ray tracing, AMD uses its existing shader cores along with a dedicated ray accelerator unit—one for each CU.
