What does this tell us overall? A few things. We don’t know how much performance scaling Apple should be picking up off a 4+4 core configuration - the M1 is just too new - so we can’t say much about that situation at the moment. Apple’s scaling factor is 4.57, implying the SoC picks up ~1 Firestorm core worth of performance from its IceStorm cluster, while AMD is clearly power limited in terms of improvement.

This is expected - Apple has a 4+4 CPU configuration, while AMD is using a full eight CPU cores. Apple’s M1 scores may not be faster than 98 percent of laptops, but they definitely fall within the range of competitive results in products AMD and Intel currently sell.ĪMD pulls ahead decisively in multi-threaded mode. It’s also evidence that Apple is capable of building a CPU that competes with AMD and Intel overall. This is, of course, still an AMD win on raw performance, but it may very well be an Apple win in terms of performance per watt. AMD has a 1.27x clock advantage, but only a 1.15x performance advantage. If we assume that Apple’s M1 runs at a constant speed of 3.2GHz (unlikely, but we’ll assume it for these purposes), it means AMD is winning this comparison thanks to higher clocks, not higher baseline efficiency. In single-threaded performance, AMD is 1.15x faster when operating in a power envelope that is nominally 1.5x larger. All power calculations derived from TDP are back-of-the-envelope approximates.
While we can discuss the TDP ranges of the products as defined by Apple, TDP is not identical to power consumption and cannot be treated as equivalent to it. If either chip has an advantage here, it’s going to be AMD.

We don’t know if the M1 being tested comes from the Mac Mini or from the MacBook Air - the M1 inside the Mini and the MacBook Pro is actively cooled, while the MacBook Air is not. We’ll be comparing against the 4800U, not the 4800HS below.Ī few caveats: We are comparing the performance of a possibly fanless system intended to run in 5-10W envelopes against systems equipped with fans that are often allowed to peak outside 15W for short intervals as part of turbo behavior. Having an extra 25-35W of power to work with changes the performance equation. The 4800HS is 1.08x faster in ST and 1.45x faster in MT. This weakens AMD’s position in this comparison and highlights the importance of testing in as similar a TDP bracket as possible.
The Ryzen 7 4800U scored 7301 in multi-threaded and 1139 in single-threaded, for a total multi-threaded ratio of 6.41x. The Ryzen 5 3600X is a very poor point of comparison for the M1, but I’ve got access to a Ryzen 4800U, and I ran Cinebench R23 for this article. We’ll start with Cinebench R23, the latest in a long line of rendering tests built by Maxon to highlight the performance of its Cinema 4D software.
Now, new data from two additional benchmarks suggests a more nuanced picture - though not necessarily a very friendly one for AMD or Intel. Last week, Apple’s M1 SoC announcement and some initial benchmark data painted a picture of a formidable ARM-based laptop core that could challenge the best AMD and Intel have to offer.
