AMD RDNA 2 impresses as integrated Radeon 600M GPU for Ryzen 6000 APUs, delivers near GTX 1060 performance in Cyberpunk 2077

AMD recently introduced its Ryzen 6000 Rembrandt APUs which received critical acclaim due to their industry-leading efficiency in the mobility segment. A crucial aspect included in the Ryzen 6000 APUs is the integrated Radeon 600M GPU powered by RDNA 2 which offers incredible performance compared to competing iGPUs and even discrete GPUs.

AMD Ryzen 6000 APUs are based on TSMC’s brand new 6nm process node which has allowed the Red Team to extract even more performance from Zen 3 cores in their “Zen 3+” iteration. But while the CPU side offers higher performance per watt, the graphics side focuses on delivering both better performance and greater efficiency thanks to the RDNA 2 graphics architecture.

AMD Radeon RX 600M series integrated GPUs are those adopted by Ryzen 6000 APUs, offering up to 12 compute units for 768 cores and up to 2.4 GHz GPU frequencies. Radeon 600M GPUs pack a 50% larger compute engine than early Vega iGPUs, 50% higher bandwidth, twice the L2 cache, and twice the rendering backends (RB+).

The Radeon RX 600M is split into two SKUs, the Radeon 680M which is featured on Ryzen 9 and Ryzen 7 chips, containing the full 12 CU and 2.4 GHz (4 RB+) configuration while the Radeon 660M powers the APUs Ryzen 5 with up to 6 CUs, 1.9 GHz clocks and 2 rendering backends. As for the numbers, AMD has acknowledged that the Radeon 600M series can play just about any game at 1080p with a smooth frame rate over 40 FPS and even over 60 FPS in some titles.

Its performance is said to be much faster than NVIDIA’s GeForce MX450 (25W) GPU which comes as a discrete solution and can even outperform the GeForce GTX 1650M Max-Q solution when FSR is enabled. FSR obviously gives AMD’s RDNA 2 base architecture a huge advantage, as DLSS is only supported by RTX solutions.

Now in the benchmarks presented by computer base, you can see that the AMD Radeon 680M on the Ryzen 9 6900HS delivers nearly a 50% performance boost over the Vega 8 iGPU on the Ryzen 7 5700G in Cyberpunk 2077 (1080p, Low Preset). This is impressive considering the GTX 1060 is only 19% faster when running at a TDP of 120W+. Computerbase says the benchmark was run without FSR enabled, so if that technology was enabled, we can definitely see the 680M match or even outperform one of the more popular discrete graphics solutions.

Another advantage of the RDNA 2 architecture on the Radeon 680M graphics chip is that it comes with ray tracing capabilities that NVIDIA GTX solutions lack. In this case, the 680M delivers up to 2x the ray tracing performance compared to the NVIDIA GeForce RTX 3050 Mobility (60W) in 3DMark Port Royal. The 4GB memory on the RTX 3050 is said to be not enough for the benchmark, but the GPU runs from shared system memory, which is a win-win for integrated graphics. The same could end up being true when comparing the RX 6500 XT with the 680M.

Go from official benchmarks to tests of independent reviewers, we find that the Radeon 680M and 660M outperform NVIDIA’s MX450 (25W) solution, and the high-end chip should also outperform the newly released MX550 chips. It’s a total bloodbath for Intel and its Iris Xe solutions which are sorely lacking in RDNA 2 chips.

Once again, with FSR, these chips can outperform NVIDIA’s current mainstream lineup, which is great news for PC gamers on a budget. This is one of the reasons Intel is investing in using Arc GPU chips in their next-gen processors like Meteor Lake and beyond to have a solid answer to AMD’s RDNA-powered iGPUs. All of this means that in a few years we will definitely have iGPUs offering performance comparable to entry-level and even mainstream discrete GPUs. While dGPUs will continue to offer more performance, they will require more power, as we are currently seeing in high-end options and even some consumer options. So gamers on a budget who don’t want to invest in expensive, power-hungry chips can stop there by using integrated solutions for their laptop and desktop needs.
