One of AMD’s strengths is undoubtedly the entire portfolio of graphics technologies, knowledge and people they acquired over a decade ago when they purchased ATI. This gave them an edge for their integrated GPUs over the competition. But how do the Radeon 680M and RX 660M built into your Ryzen 6000 APUs perform compared to other solutions?
AMD has dubbed the iGPUs inside its Ryzen 6000 APUs as the RX 660M and RX 680M respectively. The former have a configuration of 6 compute units, while the latter have 12 compute units. This is the biggest graphics architecture change in Ryzen APUs since their first generation, going from the Vega architecture already veteran and proven to the most effective and efficient. RDNA 2.
Its superiority over previous AMD solutions is therefore more than proven. But how does it compare to entry-level integrated GPUs like the NVIDIA MX450? Well, quite favorably and in favor of AMD’s solution. And no, it’s not a claim that we make without any basis.
Here’s how the Radeon 680M and 660M work, the Ryzen 600 iGPU
Many laptop models come with a dedicated GPU, so it’s on a separate chip from the CPU. NVIDIA MX450. which is based on GPU TU117 of the same brand, the same used in the various models of GTX 1650, but limited to one 25W TDP. Its configuration is 896 units in FP32 or CUDA coresa figure higher even than the RX 680M integrated in the AMD Ryzen 6000.
How do they compare? Well, if we take the cues from 3D mark as for example in fire strike we can see how the Ryzen 7 6800H with 7573 dots gives a better result with its RX 680M than the 5539 dots of the NVIDIA MX 450. Instead, the 660M of the Ryzen 5 6600H is a bit short with 5041 dots
In other 3D Mark benchmarks such as Port Royal, the RX 680M even outperforms the NVIDIA RTX 3050, although the reason in this case is not having enough VRAM. Since said performance test does not work well. It is therefore not a limitation in raw power, but in storage capacity of the graphics card.
AMD’s RX 680M versus NVIDIA’s MX 450
However, in real applications things change and as you can see in the graph above these lines the NVIDIA MX 450 has some advantage frames in some games and vice versa. Let’s not forget that the performance of the NVIDIA GPU is good enough for many manufacturers to include it in their laptops. The fact that AMD’s 600M iGPUs can achieve the same performance is a torpedo in NVIDIA’s waterline, as they can save that part for this class of laptops.
RDNA 2 is a Huge Advantage in Integrated GPUs for AMD
Without leaving the AMD Radeon 600M GPUs, other benchmarks were seen where the graphics performance of a Ryzen 7 6800H without a dedicated graphics card is compared in Cyberpunk 2077. where to go Full HD resolution in low and without the active FSR the Radeon 680M which has as iGPU oscillates between the 35 and 42 FPS. A figure that does not seem very spectacular, but if we take into account that a Ryzen 7 5800U remains among the 16 and 18 frames per secondOr, it is very clear from Lisa Su that they have gone for RDNA 2 architecture in their new APUs.
The difference is also visible in the 3D Mark’s Night Raid test where the Radeon 680M achieved between 26,235 points and 33,000 points. A figure well above 17,244 points from the Ryzen 7 5800U and its Radeon Vega 8 GPU which remains between 14890 points and 17244 points. One of the benefits of the higher bandwidth remains the new DDR5 memory.
