Architectural Differences

  1. Cache: The AMD Ryzen 9 7945HX has a larger L3 Cache of 64MB, which provides more storage space for frequently accessed data. The Intel Core i9 13980HX has a smaller L3 cache of 36MB. This lower cache for the Intel processor can significantly affect performance, especially in games.
  2. Cores: The AMD Ryzen 9 7945HX features 16 cores and 32 threads. On the other hand, the Intel Core i9 13980HX has 8 performance cores and 16 efficiency cores. The more powerful cores on the AMD processor can help it leverage more performance.
  3. TDP: The AMD Ryzen 9 7945HX has a TDP range of 30W to 150W. In contrast, the Intel Core i9 13980HX has a TDP range of 30W to 130W.
  4. Clock Speeds: The AMD Ryzen 9 7945HX operates at a base clock speed of 2500MHz, which can boost up to 5400MHz. On the other hand, the Intel Core i9 13980HX has a base clock speed of 1600MHz that can boost up to 5600MHz. The lower base clock on the Intel works out to the processor not overworking itself when you don’t need power, and the higher boost clock can certainly help when you do.
  5. Processing Nodes: The AMD Ryzen 9 7945HX is based on a 5nm manufacturing process, which offers improved power efficiency and potential for higher performance compared to the 7nm technology used in the Intel Core i9 13980HX.

In the convoluted world of mobile processors, AMD and Intel have been battling it out generation after generation to see who makes the best mobile CPU. In the Ryzen 9 7945HX vs Core i9 13980HX comparison, we will see which processor reigns supreme from the latest generation of processors from Team Red and Team Blue.


Productivity Benchmarks

Having taken a look at the different approaches both Intel and AMD take to making the best CPU they possibly can, in this part of the Ryzen 9 7945HX Vs Core i9 13980HX comparison, we will take a look at the performance of both these chips in real-world workloads.

We used the Ryzen-equipped, top-tier Asus Scar 17 and the Intel-equipped Scar 18 to compare these two processors. There is a slight difference in the size of these laptops, but the smaller size of the AMD machine is far from a limiter on the performance. All other specifications of these laptops were identical.

Without further ado, let’s get into the benchmarks.

Battery Life

Battery Life Performance
