AMD Ryzen 7 6800H and Ryzen 5 6600H's RDNA2 iGPUs trounce similarly-specced Intel and Nvidia counterparts in leaked benchmarks
AMD's Ryzen 6000 Rembrandt processors, while more power-efficient than its predecessor, is all about its integrated RDNA2-based iGPU. AMD made lofty claims about its performance by stating that it could perform an Nvidia GeForce GTX 1650 mobile in some titles. Now, a Zhihu user has cleared the air a little by benchmarking the AMD Ryzen 5 6600H and Ryzen 7 6800H. The CPU and iGPU have been tested quite thoroughly against last year's Ryzen chips as well as 12th-generation Intel Alder Lake processors.
Starting with CPU performance, the AMD Ryzen 5 6600H and Ryzen 7 6800H lag behind their similarly-specced Alder Lake counterparts, the Intel Core i5-12500H and Core i7-12700H, respectively. It is hardly surprising because leaked benchmarks from earlier told a similar tale. Besides, the comparison is unfair given that AMD's parts still use Zen 3-based cores, albeit with a few tweaks.
In 3D Mark's suite of benchmarks, the AMD Ryzen 7 6800H's Radeon 680M iGPU with 12 CUs handily outperforms the Nvidia GeForce MX450. The 6 CU iGPU on the Ryzen 5 6600H beats the Core i5-12500H's Iris Xe iGPU, but not by a lot. However, both Rembrandt processors do trounce last year's AMD Ryzen 9 5900HS's Vega-based iGPU. It'll be interesting to see how they fare against the upcoming GeForce MX550, which already looks obsolete based on its few appearances online.
The result is replicated in 1080p gaming tests across several e-sports and AAA titles, with the Ryzen 7 6800H's iGPU managing to stay ahead of the pack, followed closely by the Ryzen 5 6600H. One can theoretically play some AAA titles at 1080p 60 FPS by tweaking a few settings here and there- an impressive feat for an integrated GPU.
It is refreshing to see AMD shake up the low-end iGPU market, which has remained largely stagnant until now. They could even give some older dGPUs a run for the money with the right memory and power profiles. Besides, the benchmarks listed above were likely run on pre-production hardware and the numbers are bound to get better with off the shelf parts and stable drivers.
