AMD Radeon 680M RDNA2 iGPU Is Faster Than GeForce MX450 According To New Benchmark Results

AMD Ryzen 6000 series features reworked Zen3+ architecture on a 6nm node, but the most significant upgrade has occurred in the graphics subsystem, which is updated to 12 Compute Units based on RDNA2 microarchitecture.

AMD Radeon 660M and 680M are integrated solutions into Ryzen 6000 APUs for laptops and desktops. RDNA2 offers newer architecture as compared to Vega and gives higher performance and also support for raytracing.

The review on Zhihu illustrates the comparison between Radeon 600M potential and the GeForce MX450, a Pascal (GP107) based discrete model manufactured for ultra-thin laptops.

The 3DMark tests prove Radeon 680M to be faster than GeForce MX450 25W, giving better performance in nearly all tests. Actually, the RDNA2 based solution even supports ray tracing, this specification is deficient in AMD Ryzen 4000/5000 Vega GPU or Intel Xe-LP GPUs incorporated into Alder Lake mobile CPUs.

The matter of GPU efficiency based on TDP configuration is also elaborated in the review. The Ryzen 6000HS lineup, known as the first ever“Rembrandt” APUs to be released, is 35W by default. The reviewer also discussed that 25W Radeon 680M iGPU can gain a further 38% simply by increasing the TDP to 42W. However, it is not applicable to Radeon 660M (a cut-down RDNA2 iGPU) which only gains 9% when going from 25W to 42W.

ComputerBase is testing a Ryzen 6000 laptop and has declared that Radeon 680M is actually faster than GeForce RTX 3050 Laptop GPU in 3DMark Port Royal. This is a raytracing test involving hardware-accelerated units possessed by NVIDIA Ampere and AMD RDNA2 architectures.
Reportedly, PurePC also carried out a few tests using the latest BIOS for the ROG STRIX G15 laptop (Ryzen 7 6800H based). The Radeon 600M GPU gives better performance than both GeForce MX450 (25W) and Intel Xe-LP (i7-11370H) in 1080p tests conducted by Lenovo.

The Ryzen 6000H and 6000U series is anticipated to be released by AMD in the coming weeks. The Desktop APU (6000G) series is also expected to be introduced by the end of 2022. As GPU clocks have increased, desktop Rembrandt APUs can probably catch up to the GTX 16 series.
