Ryzen Mobile 5 4500U-hexacore review appears online
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 | Base / (Turbo clock) | L3 cache | TDP | GPU | Max. GPU clock |
|---|---|---|---|---|---|---|---|---|
| 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.
| Acer Swift 3 SF314 ‑4 | Acer Swift 3 SF314-42 | |
|---|---|---|
| Processor | Ryzen 5 3500U | Ryzen 5 4500U |
| Cinebench R15 CPU Multi | 646 | 785 |
| Cinebench R 20 CPU (Multi-Core) | 1294 | 1843 |
| 3DMark Time Spy | 742 | 947 |
| 3DMark Fire Strike | 2433 | 2641 |
| PCMark 10 | 3907 | 5024 |
| Geekbench 5 Single-core | 886 | 1074 |
| Geekbench 5 Multi-core | 3067 | 4282 |

interesting, the 6 CU vega 1.5ghz are 6% "slower" than the 8 * 1.2ghz
and 8% faster in fire strike and 27% faster in time spy!!!
so the improved design appear to works fine.
but we have to see in depth the speed of the ram and the impact on the results.

I was able to add 10-20% performance, can we say the same for AMD solution? I would like to see some test both side with enabled and disable multithreading and games and non games.. maybe someone did that?
I don't recall HT ever being a unanimously faster solution. It's faster in a select few cases, particularly ones where a single task isn't multi-threaded. HT is basically just a way to keep a pipeline busier.

This CPUs look interesting but for me even the current Ryzen laptops are good enough. I´m eyeing an Asus laptop with the 3500/3700u chip and if they drop the prices considerably after the realease of Ryzen, i may get one of them.

The 3700h/u is a 4core part just be aware.

If nothing changed Intels Hyperthreading is give you much better performance that AMD SMT bonus, i remember when enabling SMT gave you actually worse performance in some games.. I hope that situation is now better, but i dont aim on it with present gaming or other benchmarks..
True is that Intel had much more time to optimize such technology, some same as compilers etc. I was introduced in 2002 with some Pentium 4.
