AMD's Zen 4 CPUs for laptops have finally arrived and the new Ryzen 9 7945HX shows an impressive multi-core performance in our initial benchmarks. Intel's Raptor lake Core i9-13980HX is beaten, even though AMD's new CPU consumes significantly less power. Update: Performance at lower TDP levels

We finally have the opportunity to test the first mobile Zen 4 processor from AMD. It is the new high-end chip Ryzen 9 7945HX with 16 full-fledged Zen 4 cores including hyper threading, which means the chip can execute up to 32 threads simultaneously. We have listed all the specs in our Tech section and we will also publish a comprehensive analyses als well as comparison article at a later point, but we still want to share our initial impressions with you. The full review of the new Asus Zephyrus Duo 16 with the Ryzen 9 7945HX and the Nvidia GeForce RTX 4090 Laptop will also follow soon. For this article, however, we will focus on the CPU performance with some synthetic processor benchmarks as well as some gaming tests.

Single-Core Performance

The new Ryzen 9 7945HX can reach up to 5.4 GHz on a single core and we can confirm this value during our benchmarks. All in all, AMD can almost close the gap to Intel, only the Core i9-13980HX still has a slightly advantage thanks to its high single-core turbo of up to 5.6 GHz. However, AMD is better in terms of power consumption: We measure 27W for the cores, while the performance cores in the Intel Core i9-13980HX consume between 34-36 Watts. 

The performance advantage over the old Ryzen 9 6900HX with the Zen3+ cores is also impressive and we see an average advantage of 27 % in our single-core benchmarks.

* ... smaller is better

The performance of the new Zen 4 processor is even more impressive when you look at the power consumption. All the Intel HX rivals usually consume much more than 150 Watts, but the Ryzen 9 7945HX tops out at 120 Watts. The two following pictures show the CPU data of the Ryzen 9 7945HX as well as the Core i9-13980HX in a single Cinebench R23 Multi run. We also limited the Core i9-13980HX to 120 Watts and got 28333 point sin CB R23 Multi compared to 34521 points for the Ryzen 9 7945HX. This means the new Zen 4 chip is roughly 22 % faster (in multi-core tests) at the same power consumption.

Update - Performance at lower TDP levels

In addition to the default power levels, we also checked the performance of the new Ryzen 9 7945HX at lower TDP values and the results are extremely good, which is visivible in the following table. We also included the results for the Intel Core i9-13980HX at the same power levels.

Cinebench R23 Multi Score
TDP Core i9-13980HX Ryzen 9 7945HX Difference
unlimited 33052 34521 +4 %
100 Watts 26507 33487 +26 %
80 Watts 23766 31588 +33 %
55 Watts 19478 26191 +34 %

It is very obvious that Intel's best Raptor Lake mobile processor does not stand a chance against the new Zen 4 CPU at similar TDP levels. The sweet spot for the Ryzen 9 7945HX is definitely in the range between 80-100 Watts where we can only see a minor performance deficit.

Initial Verdict: AMD has the best mobile processor

The benchmark results above obviously do not give us a full picture yet, but the initial results are extremely positive. AMD managed to close the gap in terms of single-core performance with lower power consumption. The new Zen 4 chip is even faster in multi-core benchmarks and still consumes considerably less power at just 120 Watts, which means laptop manufacturer get more headroom for the cooling of the GPU, for example.

We are currently working on a comprehensive analysis article as well as the review of the new Asus Zephyrus Duo 16 with the Ryzen 9 7945HX in combination with the new Nvidia GeForce RTX 4090 Laptop. It seems AMD's Zen 4 chips have an advantage over Intel, but we also have to wait and see if there will be a sufficient number of laptop models with the new CPUs. AMD already offered the best mobile CPU for thin and light notebooks with the Ryzen 7 6800U, but the availability was very limited and customers often did not have an alaternative to Intel CPUs.
