日本[Comparison] 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.
You can find more information about both processors here: AMD Ryzen 9 7945HX / Intel Core i7-12700H
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.
Specs table
| AMD Ryzen 9 7945HX | Intel Core i7-12700H | |
|---|---|---|
| Architecture | Zen 4 | Alder Lake-H |
| Cores / Threads | 16/32 | 14/20 |
| Clock Speeds – Base/Boost | 2.50 – 5.45 GHz | 1.70 – 4.70 GHz |
| Cache | 81MB | 24MB |
| Lithography | 5nm | 10nm |
| TDP | 55-75W | 45W |
| Memory type | DDR5-5200 | DDR5-4800, LPDDR5-5200, DDR4-3200, LPDDR4x-4267 |
| Integrated GPU | AMD Radeon 610M | Intel Iris Xe Graphics G7 (96EU) |
Performance
In the Cinebench R23 test, which is one of the most widely used benchmarks for processors, the Ryzen 9 shows more than double the score, with a lead of 108%.
Results are from the Cinebench R23 CPU test (the higher the score, the better)
Conclusion
The new big dog that AMD is offering will surely ruffle some feathers in Intel’s camp, as it shows that it’s got the power to compete with the latest 13th Gen Raptor Lake chips as well (more comparisons are coming soon). The raw increase in the core count is showing that AMD is not afraid to play, as it was the first one to start the trend in the desktop CPU world, as Intel held a hegemony over the quad-core CPU model for a very long time. 2023 is looking good so far, as the CPU landscape in the laptop space is becoming more competitive again, which makes us very happy. If only manufacturers would lower prices just a bit, as pairing a modern CPU with 40-series graphics has become an expensive endeavor.
