Zen primer out of the way, let's get to the leaked scores. There are two of them—one for 3DMark's Fire Strike benchmark, and the other for 3DMark's Time Spy test. Here's a look at the Fire Strike run...
Focusing on the CPU alone, the Physics score is the one we are interested in, and that checks in at 17,466. For context, @_rogame rounded up the following data points...
- Ryzen 7 4800HS (8C/16T, 2.9GHz-4.2GHz): 20,970
- Core i7-10750H (6C/12T, 2.6GHz-4.7GHz): 17,921
- Ryzen 5 4600H (6C/12T, 3GHz-4GHz): 17,466
- Ryzen 5 4500U (6C/6T, 2.3GHz-4GHz): 10,042
Here's a look at the Time Spy benchmark run...
In the Time Spy benchmark, the Ryzen 5 4600H posts a CPU score of 6,499. Here are some other data point for context...
- Ryzen 7 4800HS (8C/16T, 2.9GHz-4.2GHz): 8,868
- Core i7-10750H (6C/12T, 2.6GHz-4.7GHz): 6,761
- Ryzen 5 4600H (6C/12T, 3GHz-4GHz): 6,499
- Ryzen 5 4500U (6C/6T, 2.3GHz-4GHz): 3,272
Once again, we see the Ryzen 5 4600H coming in close behind the Core i7-10750H, despite a 700MHz slower boost clock. AMD's chip is also working with less L3 cache (8MB versus 12MB).
We can only derive so much from leaked benchmarks. That said, if these results are an accurate reflection of performance to come, then it will really come down to pricing. The CPU numbers are rather close between the Ryzen 5 4600H and Core i7-10750H. And of course AMD's chips are rocking onboard graphics based on the company's Vega GPU architecture, so that's a bonus (though a shift to Navi would have been appreciated).
The fun is about to begin—AMD said there will be a dozen Ryzen 4000 laptops launching this quarter, and more than 100 designs by the end of the year.
