The AMD Ryzen 5 6600H processor has finally made its way onto PassMark where it has produced synthetic benchmark results that put it into close-quarter confrontation with the Intel Core i5-12600H. However, while the Alder Lake part has to make do with Iris XE Graphics (80 EUs), the Rembrandt chip can boast of having an RDNA2-powered Radeon 660M iGPU.

It was a smart move by AMD to incorporate RDNA2 microarchitecture into its Zen 3+ Rembrandt APUs, as it has given the chips a distinct advantage over both their predecessors and Intel competitors. The Ryzen 5 6600H’s PassMark scores of 3,303 (single thread) and 20,085 (average CPU Mark test suite) show the Zen 3+ processor to be a worthy rival of the Intel Core i5-12600H despite some noteworthy differences.

While the Alder Lake part is actually ahead on this particular benchmark site in both single-thread testing (+8.48%) and the multi-test suite (+4.56%), it also sports a core-count advantage over the Rembrandt chip. The Ryzen 5 6600H has 6 cores and 12 threads whereas the Intel Core i5-12600H powers along with 12 cores (4x performance cores + 8x efficient cores) and 16 threads. Both are 45 W processors that share the same 4.5 GHz top speed.

At first glance, it would seem that the i5-12600H would be the better selection in a face-off situation; however, this time around AMD’s ace up the sleeve has been the presence of RDNA2 iGPUs. In the Ryzen 5 6600H there is the Radeon 660M, which despite not being the flagship iGPU in the series still outpowers the Intel iGPU. For instance, we currently have a 3DMark Time Spy score comparison that positions the AMD solution +25% ahead of the median score for the Iris XE G7 80 EU system, and that’s with a lower-power APU (Ryzen 5 6600U).

In comparison to its predecessor, the AMD Ryzen 5 6600H delivers +11.06% (single thread) and +16.96% (multi) performance improvements, which are nothing to be sneezed at. The Radeon 660M iGPU is clearly an upgrade over the Ryzen 5 5600H’s Vega 7 part, and its boost core speed of 1,900 MHz is beyond both the Intel rival (400-1,350 MHz) and the predecessor (1,800 MHz). Laptop shoppers can either consider choosing a device with the Alder Lake part for processing supremacy or with the Rembrandt chip for all-round goodness with graphics flair.
