AMD Ryzen 9 7945HX vs Intel Core i7-12700H – A quick warmup for AMD

 


Last year AMD took a big beating, but will Zen 4 finally punch back and be a worthwhile competitor to Intel? Today we’re answering the question by comparing the new AMD Ryzen 9 7945HX against the tried and tested Core i7-12700H, the epitome of high performance that can be found readily available in a bunch of devices.



Instead of using the modern big.LITTLE philosophy when it comes to CPU design, AMD is just throwing more cores at the problem as a way of offering more performance. The Ryzen 9 comes with 16 cores and 32 threads, as well as a higher 55W power limit, which on paper sounds like a deadly combination. What makes this an even crazier ordeal is the 81MB of total cache that’s available, which is the highest that we’ve ever seen in a laptop CPU. As for the Core i7-12700H, it’s a pretty well-known processor at this point, with 14 cores and 20 threads, as well as a lower 45W TDP.
