AMD Ryzen AI 7 345 vs Intel Core Ultra 5 245T Comparison

# Where Each One Wins

The recorded benchmark data is unambiguous: the Intel Core Ultra 5 245T wins every single head-to-head test in the database. Across 15 benchmark comparisons, the Intel part takes all of them, leaving the AMD Ryzen AI 7 345 with zero wins. This is a rare outcome in the database, as most processor comparisons show at least some split based on workload characteristics.

The most decisive Intel victories come in multi-threaded rendering workloads. In Cinebench R23 multi-core, the Intel Core Ultra 5 245T scores 26208 against 11461 for the AMD Ryzen AI 7 345, a gap of 56.3%. The Cinebench R15 multi-core test shows a similar pattern: 2641 versus 1712, a 35.2% difference. These results indicate that the Intel part delivers substantially higher sustained multi-core throughput, which is relevant for rendering, video encoding, and other heavily parallel tasks.

Single-thread performance also favors Intel, but by a smaller margin. The Cinebench R23 single-core score for Intel is 3699 versus 1818 for AMD, a 50.9% lead. The PassMark single-thread test shows a narrower gap: 4367 versus 3875, an 11.3% difference. This suggests that while Intel holds the single-core advantage, the gap is less extreme than in multi-core workloads.

Math-intensive workloads show the largest deltas. The PassMark floating point math test gives Intel a score of 108499 versus 42621 for AMD, a 60.7% difference. The PassMark find prime numbers test is even more lopsided: 324 versus 62, an 80.9% gap. These results point to a substantial advantage for Intel in scientific computing and number-crunching scenarios.

Encryption and compression workloads also favor Intel. The PassMark data encryption test shows 23656 versus 11814, a 50.1% difference, while data compression yields 283812 versus 237484, a 16.3% gap. The latter is one of the closest results between the two processors, indicating that AMD is more competitive in compression-style workloads.

The AMD Ryzen AI 7 345 does not win any category in the database, but its relative performance varies. In random string sorting, the gap is 27.2% (34931 versus 25435), while in extended instructions it narrows to 23% (22071 versus 17003). The Intel part leads in every measured metric, but the magnitude of the lead depends heavily on the workload type.

# Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 345 uses the Krackan Point codename with a Ryzen AI 300 generation designation, built on a 4 nm process at TSMC. It houses 6 cores and 12 threads, with a base clock of 2.00 GHz and a boost clock of 4.60 GHz. The Intel Core Ultra 5 245T belongs to the Core Ultra Series 2, uses the Arrow Lake-S architecture, and is fabricated on a 3 nm process, also by TSMC. It has 14 cores and 14 threads, with a base clock of 2.20 GHz and a boost clock of 5.10 GHz.

The core count difference is significant: Intel offers 14 cores versus AMD's 6, and the thread counts differ as well (14 versus 12). The Intel part does not use simultaneous multithreading, giving it one thread per core, while AMD uses its standard two threads per core design. This explains why the Intel part has more cores but only two more threads.

Cache hierarchies also diverge sharply. The AMD chip has 80 KB of L1 cache per core, 1 MB of L2 per core, and 4 MB of L3 cache total. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The L3 cache difference is particularly large: 24 MB versus 4 MB, a 6x gap that contributes to Intel's advantage in cache-sensitive workloads.

Memory support differs as well. The AMD processor supports DDR5 and LPDDR5X memory, while the Intel part supports DDR5 only. Both use dual-channel memory buses, but the Intel chip has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s for AMD. The Intel part also supports ECC memory, which the AMD chip does not.

PCIe connectivity is another differentiator. The Intel Core Ultra 5 245T provides Gen 5 with 20 lanes (CPU only), while the AMD Ryzen AI 7 345 offers Gen 4 with 14 lanes. This gives Intel a newer PCIe generation and more available lanes for expansion.

Integrated graphics also differ. The AMD chip uses the Radeon 840M, while the Intel part has Arc Xe-LPG Graphics 64EU. The database does not include graphics benchmarks, so relative GPU performance cannot be assessed from the recorded data.

The Intel processor includes a transistor count of 17,800 million and a die size of 243 mm², while the AMD chip does not have these figures recorded. Intel's TDP is 65 watts versus AMD's 28 watts, reflecting the desktop versus mobile market segmentation. The AMD chip uses AMD Socket FP8, while Intel uses Socket 1851.

# The Verdict

The data shows a clear performance hierarchy between these two processors. The Intel Core Ultra 5 245T outperforms the AMD Ryzen AI 7 345 in every benchmark recorded in the database, with leads ranging from 11.3% in PassMark single-thread to 80.9% in PassMark find prime numbers. The Intel part also holds a higher percentile ranking among all CPUs: 86 versus 81 for AMD.

The Intel Core Ultra 5 245T is positioned for desktop systems with its 65 watt TDP, Socket 1851, and PCIe Gen 5 support. Its 14 cores and 24 MB of L3 cache make it the stronger choice for multi-threaded desktop workloads, rendering, and compute-heavy tasks. The AMD Ryzen AI 7 345, with its 28 watt TDP and mobile socket, targets portable systems where power efficiency matters more than raw throughput.

The AMD part does have some redeeming qualities, even if they do not appear in the benchmark scores. It supports LPDDR5X memory, which is common in mobile platforms, and its lower TDP makes it suitable for thin-and-light laptops. However, the database shows no workload where the AMD chip comes out ahead.

For users who prioritize multi-core performance, the Intel Core Ultra 5 245T is the clear choice based on the recorded data. For those building a desktop system with expansion needs, the Intel part's PCIe Gen 5 support and 20 lanes are substantial advantages. The AMD chip remains a viable mobile option, but the benchmark data does not show any scenario where it beats the Intel part.
