AMD Ryzen 7 8745HX vs Intel Core i7-13790F Comparison

Head-to-Head Benchmarks

The recorded data paints a decisive picture in this comparison. Across all eleven head-to-head benchmark pairs, the Intel Core i7-13790F wins outright, with no tests favoring the AMD Ryzen 7 8745HX. The magnitude of the victory varies significantly by workload, revealing distinct strengths.

The largest margin comes in physics simulation. The Intel part scores 3017 versus the AMD's 1681, a 79.5% advantage. This is a massive gap, indicating that the Intel processor's architecture is substantially better suited to the physics calculations tested here. Similarly, floating-point math shows a 78.3% lead, with scores of 110512 versus 61972. These are the two largest deltas and point to a significant performance advantage in scientific and engineering workloads that rely on heavy FPU usage.

In integer math, the Intel CPU posts 151416 against the AMD's 100328, a 50.9% lead. Data compression also favors Intel heavily, with 567473 versus 363759, a 56% difference. Multi-threaded performance, as measured by the passmark_multithread test, shows the Intel i7-13790F at 44737 versus the Ryzen 7 8745HX at 31517, an advantage of 41.9%. The data encryption test shows a 45.2% lead for Intel (31703 vs 21840). Prime number finding, a test of pure integer throughput, sees Intel ahead by 30.2% (207 versus 159). Random string sorting is won by Intel by 31.7% (58607 versus 44494), which indicates a strong lead in memory access patterns and string manipulation.

The narrowest win for the Intel part is in single-threaded performance. The passmark_single_thread test shows the Intel at 4212 versus the AMD at 3879, a modest 8.6% advantage. This is still a win, but it is the only benchmark where the gap is in the single-digit percentage range. In all other tests, the Intel processor's lead is at least 26%. The data suggests that while the Intel CPU has a clear edge everywhere, its strongest performance relative to the AMD is in multi-threaded computational tasks rather than single-threaded responsiveness.

The average benchmark score, which is a composite of these and other tests, sits at 63080 for the Intel and 60104 for the AMD, a 4.9% gap in favor of Intel. The Intel CPU is placed in the 93rd percentile of all CPUs, while the AMD is in the 92nd percentile. This near match in percentile is interesting, given the Intel's decisive win in the head-to-head tests. The Intel's nearest rival is the Intel Core Ultra 7 265HX, which is 0.1% ahead, and the AMD Ryzen AI 7 450G, which is 0.4% behind. The AMD's nearest rival is the AMD Ryzen 9 7945HX, which has a 0% delta, and the Intel Core i9-14900F, which is 0.2% ahead.

Architecture Differences

The two processors are built on fundamentally different architectures and for different platforms. The Intel Core i7-13790F is based on the Raptor Lake architecture, specifically the Raptor Lake-S codename, while the AMD Ryzen 7 8745HX is built on the Zen 4 architecture with the Dragon Range codename. This difference is immediately apparent in the manufacturing process: Intel uses a 10 nm node fabricated at its own foundry, while AMD uses a 5 nm process from TSMC. The AMD's die size is a smaller 71 mm², while the Intel's is a much larger 257 mm².

The core count is the most obvious hardware difference. The Intel part has 16 cores and 24 threads, while the AMD has 8 cores and 16 threads. The Intel's advantage in the multi-threaded tests is a direct consequence of this higher core count. The L3 cache is nearly identical: 33 MB shared on the Intel versus 32 MB shared on the AMD. However, the L1 cache per core is larger on the Intel (80 KB) than on the AMD (64 KB). The L2 cache is also different, with the Intel having 2 MB per core versus 1 MB per core on the AMD.

The base and boost clocks also differ. The Intel has a base clock of 2.10 GHz and a boost of 5.20 GHz, while the AMD's base is higher at 3.60 GHz, but its boost is lower at 5.10 GHz. The higher boost clock on the Intel is a likely contributor to its single-thread win. The TDP is also lower on the AMD, at 55 versus 65 for the Intel, but the Intel's higher core count and power budget explain its performance advantage.

Another major difference is the integrated graphics. The AMD Ryzen 7 8745HX includes a Radeon 610M iGPU, while the Intel Core i7-13790F has no integrated graphics. This is a significant feature gap, as the Intel part requires a discrete GPU for any display output. The AMD's memory support is limited to DDR5, while the Intel supports both DDR4 and DDR5. Both have dual-channel memory buses, but the AMD's memory bandwidth is a listed 83.2 GB/s, a figure not provided for the Intel. The PCIe support also differs: the Intel has Gen 5 with 20 lanes, while the AMD has Gen 5 with 28 lanes.

Where Each One Wins

The Intel Core i7-13790F is the clear winner in every benchmark category recorded. Its most decisive victories are in physics (79.5% ahead) and floating-point math (78.3% ahead), making it the preferred choice for scientific computing, financial modeling, and any workload that is heavily reliant on complex calculations. Its 16-core, 24-thread configuration gives it a massive advantage in multi-threaded tasks like video rendering, 3D simulation, and data compression, where it is a 50.9% lead in integer math and 41.9% in multithreaded throughput.

The AMD Ryzen 7 8745HX has no benchmark wins to its name in this data. However, its architectural profile points to other advantages. With a smaller 5nm process node, it is likely more power-efficient, though no power or efficiency numbers are provided in the data. Its higher base clock of 3.60 GHz compared to the Intel's 2.10 GHz suggests it may have better responsiveness in low-threaded, short-duration tasks, though the Intel's higher boost clock and its 8.6% lead in single-thread tests contradicts this. The AMD also includes an integrated Radeon 610M GPU, meaning it can be used in a system without a discrete graphics card.

For a desktop user who can install a discrete GPU, the Intel Core i7-13790F is the superior performer in every benchmark. The AMD Ryzen 7 8745HX's mobile segment, its integrated graphics, and its lower TDP make it more suitable for a laptop or a compact, power-conscious system. The data does not show a single performance metric where the AMD wins, but its feature set is different, appealing to a different market segment.
