AMD Renoir Architecture: Ryzen 4000 APUs with Zen 2 and Vega Graphics in 7nm
Currently three versions of Renoir APUs are planned according to AMD:
- 15 Watt U series: For thin and light laptops. The TDP can be configured from 12 to 25 Watt and the high end version offers all 8 CPU cores. The base clock speed however is rather low, and depending on the cooling solution the long term performance may suffer.
- 35 / 45 Watt H series: Currently two versions are known of. The 35 (HS) and 45 Watt (H) versions should offer a similar performance level and offer very similar specifications. The 35 Watt versions could use selected chips. Interestingly the fastest version at launch (Ryzen 7 4800H) won't include all GPU cores, as AMD rather shifts power to the CPU cores. For the intended gaming and creator laptops, dedicated GPUs are usually used, so this should be not an issue. A Ryzen 9 version could come at a later date.
- 65 Watt D series: Intended for desktop PCs with a higher TDP and most likely higher clock speeds than the H series. Should use the existing FM4 socket.
Zen 2 CPU Architecture
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.
Integrated graphics card, still Vega based
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.
Features of the SoC
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.
