Taken from GURU3D … A website in Ukraine posted review of a laptop with a Ryzen 5 4500U online. That would be a non hyper-threading / SMT based hexa-core processor made at 7nm with a TDPof 15W. The chip performs a lot better in most benchmarks than AMD’s previous laptop processors.
The review itself contains relatively little benchmark comparisons in order to be able to assess the performance very precisely but measurements on battery life are actually very interesting. The product is an Acer Swift 3 and a 50.29 Wh battery. In a test with PCMark 8, it achieved a runtime of 7 hours and 18 minutes. With PC Mark 10 Video and PC Mark 10, on the other hand, it achieved 9 hours 44 minutes and 12 hours 4 minutes, respectively.
In the Cinebench R15 Multi the Acer laptop scores 785 points. That’s more than recent quad-cores from Intel, Intel’s hexacore with HyperThreading, the Core i7-10710U achieves a higher score in a thousand points marker. AMD Ryzen 5 4600U is a processor that does not have SMT. The processor has a Radeon Vega 6 GPU and thus has fewer shader cores than the Vega 8 and 10 GPUs of Ryzen laptop processors of previous generations, but the cores are clocked higher.
| Processor | Node | architecture | Cores / threads |

|---|---|---|---|---|---|---|---|---|
| Ryzen 5 4500U | 7 nm | Zen2 | 6/6 | 2.3 GHz (4.0 GHz) | 8 MiB | 15 W. | 6 CPU Vega | 1.5 GHz |
| Ryzen 5 3500U | 12 nm | Zen+ | 4/8 | 2.1 GHz (3.7 GHz) | 4 MB | 15 W. | 8 CU Vega | 1.2 GHz |
The Swift 3 with Ryzen 5 4500U would have great battery life. If you take some numbers from an Acer Swift 3 SF314-41 at Notebookcheck.com you can compare a bit back and forth with last gen. Laptops with Ryzen 4000 processors should be released around March or April.
