With the announcement of the Ryzen 4000 APUs (Renoir), the Intel-AMD processor battle will soon intensify in the mobility space. To tackle the monolithic Zen 2 chips, Intel is prepping its Comet Lake-H CPUs with up to 8 cores (16 threads) and boost clocks as high as 5GHz. However, in most cases, these 14nm parts won’t be able to hit those kinds of frequencies, and even if they do, they won’t sustain them for long. Unlike desktops, mobile chips have limited thermal solutions, and that already impaired the Core i7-9750H causing severe throttling and performance drops. There’s a good chance that the 10th Gen Comet Lake-H will face the same problems. A leaked benchmark comparing the Core i7-10750H and the AMD Ryzen 7 4800H indicates that that’s highly likely:
Update: UB seems to think that the Core i7-10750H is an octa-core part, but many leaks have already shown that it’ll retain its hex-core design.
UserBench is known to favor single-core performance (read: Intel) over multi-core horsepower.
But these are both octa-core parts based on a monolithic design so I believe that can be ignored this once. As you can see, here the average boost clock for the Core i7-10750H is 4.15GHz. This what most mainstream laptops will be able to sustain. Despite running at a lower 3.9GHz, the AMD Ryzen 7 4800H manages to beat its Comet Lake-H competitor by 10% in the single-core test and a meaty 20% in the multi-core benchmark.
This is about what I expect from the Ryzen 4000 Renoir parts. Unlike desktops, Intel won’t have a major frequency advantage here, and considering the high IPC of the Zen 2 core, the AMD offerings will be superior in most cases. Even in gaming, Intel won’t have an advantage as the Renoir APUs are monolithic and there’s no latency penalty hampering performance. That’s the reason why AMD has reduced the L3 cache in case you were wondering.
In real-world, scenarios, you can expect single-core performance in the same ballpark for the Renoir and Comet Lake parts but multi-core scores will be at least 20-30% higher for the former. The Ryzen 4000 powered laptops are going to hit retail in March next month. Expect a review soon 🙂
