AMD finally launched the Ryzen 4000 laptops yesterday after a prolonged wait. While most third-party reviewers are yet to get their hands on them, certain Chinese outlets have managed to snag a few units. We’ve gone through their reviews and they’re every bit as impressive as anticipated. There are two sets of benchmarks: gaming and content creation. The former consists of Assassins’ Creed Odyssey, Total War and Metro Exodus while the latter is composed of Cinebench and Photoshop benchmarks. Let’s have a look at the two.
AMD Ryzen 7 4800H vs Intel Core i7-9750H: Gaming Performance
The Ryzen 7 4800H is slightly slower than the Intel Core i7-9750H in mainstream games, however, the delta is within the margin of error. Furthermore, compared to the older Picasso APUs, this is a big step up for AMD in the mobile market. This small deficit can be attributed to the lower boost of the Renoir chips compared to the Intel Whiskey Lake parts. It’ll be interesting to see whether the operating clock of the Ryzen 9 4900H alleviates this deficiency.
AMD Ryzen 7 4800H vs Intel Core i7-9750H vs i9-9980HK: Cinebench and Photoshop
Now, let’s move onto the content creation performance. While Intel is known to have an advantage in gaming workloads, content creation and other multi-threaded workloads are AMD’s home turf. We have the Cinebench R15, R20, and Photoshop performance tests. These benchmarks compare the Ryzen 7 4800H against the Core i7-9750H and the i9-9980HK.
The former is a hex-core CPU while the latter is an octa-core part but despite that, the Renoir chip manages to beat them both. The CB R15 test sees the 4800H throttle through the course of the benchmark but R20 is fairly stable.
Remarkably, the Ryzen 7 Renoir part is more than twice as fast compared to its Picasso predecessor. The 4800H trades blows with the Core i9-9980HK while the 9750H is left far behind.
In Photoshop, the Ryzen 7 4800H overcomes the Core i9-9980HK in the overall benchmark but in most of the 16-bit tests, the latter is notably faster. Looking at the clock scaling, this appears to be due to throttling and will possibly vary from device to device:
Other than the seventh one, all the cores undergo severe throttling through the course of the benchmark. This is something that needs to be investigated further to get a better understanding of the bottleneck.
The power efficiency of Renoir laptops is also quite impressive. One of the main complaints about the older Picasso devices was with respect to battery life. They were much less efficient than the competing Intel offerings. AMD seems to have taken that rather seriously. The 4800H draws just 27W when idle and around 54-55W under load. That’s almost 50% less than Picasso.
Considering the pricing and Intel’s present portfolio, AMD appears to be in a very advantageous position to launch its first attack on the low-power notebook PC market. Stay tuned, we’ll have our reviews of the Renoir laptops up soon.
