AMD announced the Ryzen 4000 “Renoir” lineup for laptops and low-power notebooks at CES, aiming to dislodge Intel from its longstanding prominence in the mobile PC market. Based on the 7nm Zen 2 core architecture, unlike the desktop-grade Ryzen 3000 chips, these parts are monolithic in design. Paired with the improved Vega graphics processor, this will be Intel’s hardest test yet.
The Geekbench score for the Ryzen 5 4500U surfaced today and it shows the Renoir chip beating Intel’s Core i5 offerings by a satisfying margin. We’ll compare the 4500U to both the Coffee Lake-based Core i5-8250U as well as the newer Ice Lake Core i5-1035G7. Let’s have a look:
At the moment, the majority of Intel’s offerings leverage the older 14nm based Coffee Lake design, so it’s better to test the Whiskey Lake i5 first. The Core i5-8250U is utterly defeated by the Ryzen 5 4500U. In the single-core test, the Renoir chip is about 20% faster than the old Intel part while in the multi-threaded test it’s almost twice as fast. This ought to make Intel’s older laptops pretty obsolete. At the moment, only a fraction of Intel’s mobile offerings comprises of the newer 10nm Ice Lake design. The vast majority is still powered by the older Skylake core.
Even with the coming of Tiger Lake, that won’t change. The bulk orders will be fulfilled by Comet Lake, another 14nm Skylake rehash, and considering these scores, I doubt it’ll keep up with AMD’s Ryzen 4000 APUs. The only positive aspect of these chips will be the Gen12 graphics which will pack as many as 96EUs. That will be something to see.
Now, let’s have a look at the Ice lake part. Despite being Intel’s most advanced design, it still fails to keep up with the Ryzen 5 4500U in the overall multi-threaded score. The single-core performance is slightly higher (by 10-15%), owing to Ice Lake’s higher IPC. Still, this is mostly irrelevant as only a few select laptops feature the 10nm chips.
Let’s have a deeper look into Renoir’s performance to analyze its strong and weak points:
Intel’s main advantage is in AES encryption which significantly boosts its single-core score. In the rest of the tests, the two CPUs perform largely within a few percent of each other.
The results are similar in the multi-core score. Here the Intel chip is ahead only in AES encryption, while the AMD Ryzen 4500U leads in everything else and in the end, manages to come out on top. This means that there are some very positive times ahead for Team Red. We’ll keep you posted as we hear more.
