Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 PRO 8945HS uses the Zen 4 architecture with the Hawk Point codename, built on a 4 nm process at TSMC. It packs 8 cores and 16 threads, leveraging simultaneous multithreading. The Intel Core Ultra 5 225T uses the Arrow Lake architecture with the Arrow Lake-S codename, built on a 3 nm process also at TSMC, but it offers 10 cores and 10 threads with no multithreading.

The transistor counts diverge significantly. AMD's chip contains 25,000 million transistors on a 178 mm² die, while Intel's contains 17,800 million transistors on a larger 243 mm² die. The cache hierarchies also differ. AMD allocates 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3.

Clock speeds show AMD with the higher peak. The Ryzen 9 PRO 8945HS has a base clock of 4.00 GHz and a boost clock of 5.20 GHz, while the Core Ultra 5 225T has a base of 2.50 GHz and a boost of 4.90 GHz. The TDP figures move in the opposite direction: AMD is rated at 45 W, while Intel is rated at 65 W.

Memory and I/O capabilities differ as well. Both support DDR5 with a dual-channel memory bus, but AMD offers 89.6 GB/s of memory bandwidth and ECC memory support, while Intel offers 102.4 GB/s of memory bandwidth and no ECC support. For PCIe, AMD provides Gen 4 with 20 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only). The integrated graphics are the Radeon 780M for AMD and the Arc Xe-LPG Graphics 16EU for Intel.

The sockets are incompatible: AMD uses Socket FP7, while Intel uses Socket 1851. AMD's market segment is mobile, while Intel's is desktop. AMD released on 2024-04-15, while Intel's release date is 2024-12-31.

Where Each One Wins

The AMD Ryzen 9 PRO 8945HS is the clear choice for workloads that rely on integer arithmetic and data manipulation. Its 73.6% lead in integer math indicates strong general-purpose compute throughput. The 57.6% advantage in data compression and 55.2% lead in random string sorting suggest it handles memory-intensive data processing tasks with greater efficiency. The 19.8% multi-thread win and 19.3% encryption win reinforce this pattern. The Cinebench results, all showing approximately 14.5% advantages, indicate that AMD has a consistent edge in rendering and CPU-bound content creation with its 16 threads versus Intel's 10.

The Intel Core Ultra 5 225T wins in specific compute patterns. The 68% lead in prime number finding points to superior branch prediction and single-thread integer loops. The 30.3% win in physics tests suggests its architecture handles certain simulation workloads better. The 23.3% lead in floating point math shows Intel's advantage in scientific and engineering calculations. The 9.8% single-thread lead, while modest, indicates that Intel has the faster individual core for lightly threaded applications.

The percentile rankings place AMD at 88 percent versus all CPUs, while Intel sits at 82 percent. The average benchmark scores confirm the gap: AMD's average is 41,963, while Intel's is 30,468. The nearest rivals for AMD include the Intel Core i7-14700T with an average score of 41,914 (0.1% delta) and the AMD Ryzen 5 7400 at 42,055 (-0.2% delta).
