LG Ultra PC 14 review: Stamina meets performance
AMD Ryzen 7 5825U | AMD Radeon RX Vega 8 (Ryzen 4000/5000) | 14.00" | 1.3 kg
Currently three versions of Renoir APUs are planned according to AMD:
The Zen 2 cores have been introduced in the Ryzen 3000 desktop chips (Matisse, e.g. Ryzen 9 3900X) and were able to significantly improve the IPC (instructions per clock) speed and catch up and partly even overtake the Comet Lake IPC speed.
The integrated graphics card in the new Renoir chips is still based on the Vega architecture (5th generation of GCN) and not the new Navi (RDNA architecture). Interestingly, it looks like the CU (compute unit) count was not increased and for the first models even decreased. However, the GPUs now clock higher across the board thanks to the new 7nm process. Therefore, we do not expect high leaps in the GPU department, but it should still position itself on top of iGPUs.
Information on additional features of the SoC are still scarce. The integrated dual channel memory controller supports now power efficient and fast LPDDR4X-4266. PCI Express 4.0 however is not supported by Renoir (in contrast to the desktop Ryzen 3000 Matisse chips). Thunderbolt or WiFi should not be integrated in the chip (in contrast to Intel Ice Lake, that partly integrates both).
Thanks to the fast Zen 2 processor cores (and eight of them), the new 7nm process and design improvements, the Renoir chips look to be a very strong contender to Intel H and U chips (especially Comet Lake based). First benchmarks from AMD (Cinebench R20) show excellent performance for the top models of the U and H series. AMD also advertises a 2x improved performance per watt for Renoir compared to the previous generation. 30 percent of that are contributed on IPC and design improvements and 70% on 7nm process gains.
However, it always depends on the implementation in laptops on how much of the potential can be unleashed.
