For context, the Ryzen 7 7840U's iGPU has 12 RDNA 3 compute units with a max 2.7 GHz clock, while the Ryzen Z1 only has four RDNA 3 compute units at 2.8 GHz.īit_user said:Wow, the 7840U performed only 18.2% better 30 W, in spite of having 33.3% more cores (not to mention all big cores)!! It sure would be nice if they had the same memory speeds, so we could know if that's helping the Z1. Zen 4c consumes less power despite the higher recorded voltage due to the more compact design.Īs for iGPU performance, the Ryzen 7 7840U delivered up to 65% higher gaming performance than the Ryzen Z1. Zen 4c's power efficiency resides in between 1.5 GHz and 2 GHz. The V/F (voltage-to-frequency) curve for both cores overlaps at 1.5 GHz. In contrast, Zen 4c arrives at the Vmin below 1.5 GHz.

The VID (voltage identification definition) charts revealed that Zen 4 hits the Vmin (the minimal voltage that a processor requires for a workload at a particular frequency) at 2.3 GHz. Zen 4c needs a higher core voltage to reach the same clock speeds as Zen 4. The Ryzen 7 7840U outperformed the Ryzen Z1 at 15W and 30W by 53.5% and 18.2%, respectively. Regardless, the Ryzen 7 7840U was still the faster chip. Looking at the overall performance in Cinebench R23, there was a 29.8% difference between the Ryzen Z1 15W and 30W modes. That's something to consider when comparing the charts of the two devices with different power limits. Huang highlighted that the HP Elitebook 835 G10 has a default SPL (sustained power limit) of 25W, which isn't modifiable by the user. The laptop has 32GB of LPDDR5-6400 memory, so the Ryzen 7 7840U had access to more memory, albeit at slower speeds. The Ryzen 7 7840U is an octa-core chip with boost clock speeds up to 5.1 GHz.
ASUS ZEN 3 REVIEW PC
Huang compared the Ryzen Z1 handheld PC against the HP Elitebook 835 G10 with a Ryzen 7 7840U. The Ryzen Z1 had 16GB of LPDDR5X-7500 memory and operates with 15W and 30W modes.
Huang used a handheld PC with the Ryzen Z1 for testing but didn't specify the model. The 7nm chip has two Zen 4 cores and four Zen 4c cores that sport a maximum boost clock up to 4.9 GHz and 3.5 GHz. The Ryzen Z1 has a hexa-core, 12-thread design. In AMD's case, Zen 4c is nearly identical to Zen 4, except that the former is 35.4% smaller, making it twice as dense, with lower clock speeds and cache.
The advantage is that AMD's E-cores feature simultaneous multithreading, whereas Intel's E-cores lack Hyper-Threading. In contrast, AMD leverages the same Zen 4 architecture in Phoenix 2. For example, Intel utilizes two completely different architectures for the P-cores and E-cores in its hybrid chips, such as Alder Lake (Golden Cove, Gracemont) and Raptor Lake (Raptor Cove, Gracemont). However, the chipmaker's approach is a bit different from Intel's. Phoenix 2 is AMD's first foray into hybrid chips.
The Ryzen Z1 has been rumored to be a clone of the Ryzen 5 7540U for a long time now.
ASUS ZEN 3 REVIEW SERIES
It differs from AMD's Ryzen 7040U series (Phoenix) with the PHX-A1 stepping. HWiNFO, a system information, monitoring, and diagnostics utility, confirms that the Ryzen Z1, codenamed Phoenix2, is on the PHX2-A0 stepping. However, it seems that Phoenix 2 is already among us, but in the form of AMD's Ryzen Z1 series that is at the heart of handheld PC gaming devices, such as the ROG Ally. Phoenix 2 was slated to launch this year, but we still haven't seen the mobile Ryzen processors in retail laptops yet.
