Regarding single-core performance at high wattage, the Ryzen 9 7945HX was slightly slower than the Core i9 13980HX, with a score of 1951 points compared to 2193 on the Intel machine.This shows that Intel has finally overtaken AMD in terms of power efficiency, at least in terms of the highest-end mobile processors.ġ30 watts CineBench R23 Benchmark Watts (Image By Tech4Gamers) On the flip side, the Core i9 got a screen on time of 263 minutes, beating the AMD chip by a significant margin. In our proprietary youtube playback battery tests, the Ryzen 9 7945HX had 158 minutes of screen on time, which is not ideal, seeing as AMD has traditionally been the better option for a long-lasting laptop in the past.Battery Life Battery Life Performance (Image By Tech4Gamers) Without further ado, let’s get into the benchmarks. All other specifications of these laptops were identical. 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. We used the Ryzen-equipped, top-tier Asus Scar 17 and the Intel-equipped Scar 18 to compare these two processors. 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. 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.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. On the other hand, the Intel Core i9 13980HX has a base clock speed of 1600MHz that can boost up to 5600MHz. Clock Speeds: The AMD Ryzen 9 7945HX operates at a base clock speed of 2500MHz, which can boost up to 5400MHz.In contrast, the Intel Core i9 13980HX has a TDP range of 30W to 130W. TDP: The AMD Ryzen 9 7945HX has a TDP range of 30W to 150W. The more powerful cores on the AMD processor can help it leverage more performance. On the other hand, the Intel Core i9 13980HX has 8 performance cores and 16 efficiency cores.
