Recently, we have been very focused on the capabilities of AMD Rembrandt processors for laptops. The first step was the AMD Ryzen 7 6800H chip and the AMD Radeon 680M integrated graphics chip. After previous troubles with the software, the APU operation has stabilized. This affected the results of the iGPU, which outperforms everything that has been built so far with integrated graphics in mind. Now, in turn, we will focus on the performance of the AMD Ryzen 7 6800H processor itself. It will be an interesting clash, because the new Rembrandt faces the 12th generation of Intel in the form of the Alder Lake-H system: 14 cores and 20 threads Core i7-12700H. Indeed, a larger number of cores should significantly affect the performance of processors. However, I think for many people the AMD Ryzen 7 6800H will be a more interesting processor anyway. I’m not just talking about iGPU performance. The work of the APU itself makes a big impression.

AMD Ryzen 7 6800H as well as Intel Core i7-12700H are two new processors that represent the latest generations in laptops: Rembrandt and Alder Lake respectively. In the case of AMD, the changes mainly affected the graphics system, the memory controller and all multimedia facilities. Intel, in turn, focused on a hybrid architecture consisting of two types of cores: performance (Golden Cove) and efficiency (Gracemont). AMD offers 8 powerful Zen 3+ cores, while the Intel Core i7-12700H is a combination of 6 powerful P-Core cores and 8 small E-Core cores, primarily aimed at boosting multi-threaded performance without significantly increasing power consumption. I will write up front that each of these processors has its strengths and weaknesses. It is undoubtedly an interesting year, with AMD and Intel presenting a number of novelties at the same time. For people choosing a new notebook, this is a rare and therefore more interesting situation.
AMD Ryzen 7 6800H is a new processor from the Rembrandt APU family, offering 8 cores with 16 thread support. We check its performance against the Intel Core i7-12700H, that is, the new Alder Lake-H chip. In addition, we also discuss the temperatures and power consumption of the new Rembrandt system.
AMD Ryzen 7 6800H APU Rembrandt Premiere – Performance Test AMD Radeon 680M vs Intel Iris Xe Graphics vs Radeon Vega 8
Both processors have a TDP (now officially called Intel Core Processor Power) of 45W. Two laptops were used for testing – ASUS ROG Strix G15 G513RC with AMD Ryzen 7 6800H and GIGABYTE AORUS 15 with Intel Core i7-12700H. The processors operate at similar power limits, but during tests they could be tuned to run at the same power consumption – I think it would be an interesting curiosity about how two different processors, in terms of construction, handle similar power limits. The tests are chosen so that the amount of RAM used has the least possible impact on the results. AMD has a DDR5/LPDDR5 controller, Intel supports both DDR4 and DDR5, and the GIGABYTE AORUS 15 laptop in the common version has DDR4 modules. Intel’s change is that compared to Tiger Lake-H processors, the new Alder Lake-H processors support less RAM. Previously it was 128 GB, now – 64 GB. With AMD, the problem with the maximum amount of RAM supported is the same – the Rembrandt APU also supports up to 64 GB.
Other changes occurred in the course of using the PCIe 4.0 bus. This time both companies support PCIe 4.0, but Intel decided … to reduce the number of lines in its 12th generation mobile processors compared to the 11th generation (Tiger Lake-H). This time we have 16 tracks available for PCIe 4.0, 8 of which will be available for the GPU, and another 8 for PCIe 4.0 SSDs. AMD offers … more PCIe 4.0 lines than Intel, because 20. However, a maximum of 8 will be offered for the GPU, and the rest can be used, for example, for an SSD. In addition, the AMD platform compared to the Renoir and Cezanne generation will provide state-of-the-art multimedia facilities. There will be support for USB 4, WiFI 6E (modules prepared in collaboration with Qualcomm and MediaTek), HDMI 2.1, DisplayPort 2.0, HDR10, Dolby Vision and AV1 on integrated RDNA 2 graphics systems – this is the most significant change. In this regard, Intel will present everything we already have on the occasion of the eleventh generation. In short, there will be, among others Thunderbolta 4, USB 4, WiFi 6E or the AV1 codec.
