AMD Ryzen 5 7640HS vs Intel Core Ultra 5 225T Comparison

The Intel Core Ultra 5 225T and AMD Ryzen 5 7640HS are closely matched in overall average benchmark scores, with the Intel part holding a slight edge at 30468 versus 30390 for the AMD. However, the data reveals that these two CPUs have completely different performance profiles, with the Intel chip dominating multi-threaded and single-threaded workloads, while the AMD chip counters in specific memory and integer-heavy tasks. The Intel Core Ultra 5 225T wins 11 of the 15 head-to-head benchmark comparisons, but the AMD Ryzen 5 7640HS takes 4 wins in areas that matter for specialized workloads.

Head-to-Head Benchmarks

The most dramatic separation occurs in Cinebench R23 multi-core, where the Intel Core Ultra 5 225T scores 21971 against the AMD Ryzen 5 7640HS’s 12554, a massive 75% advantage. This is the single largest gap in the entire comparison, and it shows that the Intel chip’s 10 cores and 10 threads are far more effective at sustained all-core rendering than the AMD’s 6 cores and 12 threads. The single-core Cinebench R23 result is even more lopsided, with the Intel part scoring 3101 versus 1715.5 for the AMD, a 80.8% lead. This pattern holds in Cinebench R15, where the Intel chip leads by 11.9% in multi-core (2214 vs 1978) and by 15.8% in single-core (312 vs 269.5).

The Intel Core Ultra 5 225T also shows decisive wins in PassMark’s floating-point math test, scoring 82751 versus 45220 for the AMD, an 83% advantage. Similarly, the Intel part dominates the find-prime-numbers test with a 268.8% lead (284 vs 77), and the physics test with a 77.7% lead (2053 vs 1155). These results indicate that the Intel architecture is significantly stronger in scientific and simulation workloads that rely on heavy mathematical computation.

The AMD Ryzen 5 7640HS does strike back in several key areas. Its most significant win is in PassMark integer math, where it scores 73284 versus 59543 for the Intel chip, an 18.8% advantage. The AMD part also leads in data compression (269524 vs 233998, a 13.2% edge), random string sorting (31654 vs 28774, a 9.1% lead), and extended instructions (20556 vs 20083, a 2.3% edge). These results suggest that the AMD chip has a more efficient integer execution pipeline, which translates to better performance in database operations, compression utilities, and general data manipulation tasks.

In the remaining tests, the Intel Core Ultra 5 225T wins data encryption by 15.3% (18289 vs 15867), PassMark multi-thread by 10.4% (25358 vs 22979), and single-thread by 19% (4348 vs 3654). The overall average benchmark score difference is only 0.3% in favor of the Intel part, but this hides the fact that the two chips are optimized for completely different workloads.

The Verdict

The Intel Core Ultra 5 225T is the clear choice for users who prioritize rendering, scientific computing, or any workload that benefits from high floating-point throughput and strong single-core performance. Its Cinebench R23 multi-core score of 21971 is 75% higher than the AMD’s, and its single-core score is 80.8% higher, making it the superior processor for 3D modeling, video encoding, and general productivity applications that rely on single-threaded responsiveness. The 82nd percentile ranking among all CPUs, versus 81st for the AMD, confirms its overall standing, but the delta is so small that the decision should be workload-driven rather than based on aggregate scores.

The AMD Ryzen 5 7640HS is the better option for specific data-centric tasks, particularly those involving integer math, compression, and string sorting. Its 18.8% lead in integer math and 13.2% lead in data compression make it a compelling choice for developers, database administrators, or anyone running analytical workloads that process large datasets. However, the AMD chip’s 35W TDP is significantly lower than the Intel’s 65W, which suggests it may be more suitable for thermally constrained environments, though the benchmark data does not directly measure power efficiency.

For most users, the Intel Core Ultra 5 225T is the recommended part because it wins 11 out of 15 comparisons and delivers the largest performance margins in the most demanding workloads. The AMD Ryzen 5 7640HS should be selected only when the specific pattern of integer and compression performance is a known requirement, as its wins are narrower and fewer.

Architecture Differences

The Intel Core Ultra 5 225T is built on the Arrow Lake architecture, codenamed Arrow Lake-S, and manufactured on a 3 nm process by TSMC. It contains 17,800 million transistors on a 243 mm² die. The AMD Ryzen 5 7640HS uses the Zen 4 architecture, codenamed Phoenix, on a 4 nm process, also from TSMC, with 25,000 million transistors on a 178 mm² die. Despite having fewer transistors, the Intel chip has a larger die size, which reflects the different design philosophies.

The core configurations are fundamentally different. The Intel part has 10 cores and 10 threads with no hyper-threading, while the AMD part has 6 cores and 12 threads with simultaneous multi-threading. This explains why the Intel chip wins multi-threaded tests despite having fewer threads — its 10 physical cores outperform the AMD’s 6 physical cores with 12 logical threads. The L3 cache also differs, with the Intel part offering 20 MB shared versus 16 MB shared on the AMD, while the L1 and L2 caches per core are larger on the Intel part (192 KB L1 and 3 MB L2 versus 64 KB L1 and 1 MB L2 on the AMD).

The memory interface differs as well. The Intel Core Ultra 5 225T supports PCIe Gen 5 with 20 lanes, while the AMD Ryzen 5 7640HS is limited to PCIe Gen 4 with 20 lanes. The integrated graphics are also different, with the Intel chip featuring Arc Xe-LPG Graphics with 16 execution units, while the AMD part has the Radeon 760M. The Intel part does not support ECC memory, while the AMD does.

Specification Differences

The two processors differ in several key specifications. The Intel Core Ultra 5 225T has a base clock of 2.50 GHz and a boost clock of 4.90 GHz, while the AMD Ryzen 5 7640HS has a much higher base clock of 4.30 GHz and a boost clock of 5.00 GHz. Despite the higher base clock on the AMD part, the Intel chip still wins all single-threaded benchmarks, indicating that the Arrow Lake architecture has higher instructions-per-clock efficiency.

The TDP is a significant difference, with the Intel part rated at 65W and the AMD part at 35W. The Intel chip uses the Intel Socket 1851, while the AMD chip uses the AMD Socket FP8, making them incompatible with the same motherboards. The memory bandwidth also differs, with the Intel part offering 102.4 GB/s versus 89.6 GB/s on the AMD. The production status for both is active, and neither has an unlocked multiplier. The Intel part was released on 2024-12-31, while the AMD part has no recorded release date in the data.
