Did AMD just win the mobile CPU Game? – AMD Ryzen 9 7945HX + Zephyrus Duo 16 Hands-On.

Today we got something very special for you, so I hope you’re all sitting down in your chair since AMD just dropped quite the bomb.

AMD Ryzen 9 7945HX Features

This is the Asus allergies the 1st 2:16 and it’s the first notebook we got in the studio that features Team Reds all new rise in 7000 with their mobile flagship the Horizon 97945 HX. This absolute unit of a CPU comes with 16 cores in total and these are all real cores, so no hybrid approach like we have seen from Intel and since these two all support hyperthreading.

We are talking 32 frets here. Why? We will do a full review of the ciphers to a 16 at a later time. We will focus on the new CPU today, since there’s actually quite a lot to talk about, and while I do not want to spoil the fun too early, things are not looking too good for Intel here. Before we dissect the brain for this one though, let me give you an overview of what is on offer with the Zephyrus. The dual screen laptop is every bit as special as it was when we reviewed it last year, and while the chastity remains mostly unchanged, this puppy is fully loaded. Quote 2023.

Alongside the new AMD Silicon, Asus also opted for Nvidia’s RTX 4090, running at up to 175 watts, 32 gigabytes of DDR, five 4800 RAM and a two terabyte SSD. In our radio sample, the secondary display remains unchanged and is basically half of a 4K screen, but with a classy coding. The main screen gets the Mini LED treatment this time around and refreshes at 240 Hertz, so it’s most likely the same panel as we already tested.

In the M16 a few weeks ago, but as I said, more info about a dual will come at a later time. So let’s focus on AMD’s new mobile monster, the 7945 HX.

The chip is based on these and for architecture and sports team Reds chiplet design, there are two CCD clusters with eight CPU cores each manufactured in TSMC’s five nanometer process alongside a single IO die in the Zephyrus. The 16 core CPU can run with up to 120 watts in multicore scenarios, with core clocks averaging out at 4.5 gigahertz and a 10 minute Cinebench single core run, core clocks can reach up to 5.4 gigahertz, averaging.

Out at around 4.8 gigahertz, right, running at about 26 watts for a single core in our combined CPU performance rating. The horizon chip comes in at 2nd place, only yielding to the I-9 3980X, indeed Titan GT77 across several different benchmarks we tested in both single and multicore loads. What you have to put in perspective though is that the flagship Raptor leg are 9 needs about 180 to 190 watts in total to achieve this course we measured.

Which is quite a testament to AMD’s efficiency benefits we’ve been able to observe in the past. Across our benchmarks, it becomes clear that the 7945 X easily outclasses the team blue competition. Maybe not by a lot, but still it manages to achieve better scores at lower wattages.

In single core loads into the still reigns supreme, but AMD was able to minimize the performance gap here quite significantly as well. What is even more impressive is when we compare the Horizon 7000 chip to AMD’s High end offering from last year. The 6900 X we also tested in the 2022 version of the Surface Dual Cinebench R23 scores more than doubled and overall we observed an almost 70% performance improvement. Well done AMD, this is how you crash.

Party to further get an idea about Team Reds efficiency benefits. We did this in the bench run on the Titan while limiting the CPU TDP to 120 watts as well. And yeah, we get about 28,000 points, which puts the 7945 HX about 20% in front at this same power draw. Let that sink in. While all these tests are synthetic by nature to get an easily comparable baseline, we also ran some gaming benchmarks to see if there are performance benefits.
