AMD today officially announced its new notebook APUs. There are 12 new products in total, they are divided into two lines. The flagship Ryzen 5000H includes models with a TDP of 35-45 W (Ryzen 9 5980HX and Ryzen 9 5900HX support overclocking, so the TDP is even higher than 45 W) on the Zen 3 architecture, but in the Ryzen 5000U line there are models on both Zen 3 and on Zen 2, but the TDP value is the same for all models – 10-25 W.
Why it was necessary to make such a mix from APUs on different architectures within the same series, it became clear only now: models of the Lucienne family (Zen 2) are cheaper than Cezanne models (Zen 3) – they will be used in inexpensive laptops. In general, mobile Ryzen 5000s gained 19% in terms of IPC and received twice as much cache memory. All characteristics of the new products are presented in two tables below, but we will dwell on the flagships in more detail.
Ryzen 9 5980HX and Ryzen 9 5900HX each have 8 processing cores and support multithreading. The amount of cache memory L3 was 16 MB, L2 – 4 MB. The Ryzen 9 5900HX has a base frequency of 3.3 GHz, with a maximum of 4.6 GHz. The base and maximum frequencies of the Ryzen 9 5980HX are 3.4 and 4.8 GHz. The TDP for them is listed as 45+ watts, since only these two models support overclocking. It, of course, will largely be determined by the cooling subsystem of each particular laptop, but in general for high-performance mobile workstations or gaming laptops, this is an interesting opportunity. Note that the Ryzen 5000H will compete with the Intel Tiger Lake-H35 CPU, but there are only three “blue” processors in the series, while AMD has six.
AMD Ryzen 5000H APU specifications are as follows:
| HELP | Family | Architecture | # Of cores / threads | Frequency, GHz | L3 cache size, MB | GPU (number of computational units / cores) | GPU frequency, GHz | TDP, W. |
|---|---|---|---|---|---|---|---|---|
| Ryzen 9 5980HX | Cezanne H | Zen 3 | 8/16 | 3,4-4,8 | 16 | 8/512 | N / A | 45+ |
| Ryzen 9 5900HX | Cezanne H | Zen 3 | 8/16 | 3,3-4,6 | 16 | 8/512 | N / A | 45+ |
| Ryzen 9 5900H | Cezanne H | Zen 3 | 8/16 | 3,3-4,65 | 16 | 8/512 | N / A | 35-45 |
| Ryzen 9 5900HS | Cezanne H | Zen 3 | 8/16 | 3,1-4,5 | 16 | 8/512 | N / A | 35-45 |
| Ryzen 7 5800H | Cezanne H | Zen 3 | 8/16 | 3,2-4,4 | 16 | 8/512 | 2,0 | 35-45 |
| Ryzen 5 5600H | Cezanne H | Zen 3 | 6/12 | 3,1-4,1 | 8 | N / A | N / A | 35-45 |
And this is how the characteristics of the Ryzen 5000U look like:
| HELP | Family | Architecture | # Of cores / threads | Frequency, GHz | L3 cache size, MB | GPU (number of computational units / cores) | GPU frequency, GHz | TDP, W. |
|---|---|---|---|---|---|---|---|---|
| Ryzen 7 5800U | Cezanne U | Zen 3 | 8/16 | 2,0-4,4 | 16 | 8/512 | 2,0 | 10-25 |
| Ryzen 7 5700U | Lucienne U | Zen 2 | 8/16 | 1,8-4,3 | 8 | 8/512 | 1,9 | 10-25 |
| Ryzen 5 5600U | Cezanne U | Zen 3 | 6/12 | 2,3-4,3 | 12 | 7/448 | 1,8 | 10-25 |
| Ryzen 5 5500U | Lucienne U | Zen 2 | 6/12 | 2,1-4,0 | 8 | 7/448 | 1,8 | 10-25 |
| Ryzen 3 5400U | Cezanne U | Zen 3 | 4/8 | 2,6-4,0 | 8 | 6/384 | 1,6 | 10-25 |
| Ryzen 3 5300U | Lucienne U | Zen 2 | 4/8 | 2,6-3,85 | 4 | 6/384 | 1,5 | 10-25 |
All of these APUs are manufactured using the 7nm process technology. Ready-made devices based on them will go on sale in the near future, but, according to rumors, at first Ryzen 5000 laptops will be in short supply.
