AMD Ryzen AI 5 330 vs Intel Core 7 251E Comparison

AMD Ryzen AI 5 330 and Intel Core 7 251E occupy different corners of the processor market, and the recorded data shows that each has a clear purpose. The Ryzen AI 5 330 is a mobile-focused, power-efficient Zen 5 part aimed at thin-and-light laptops. The Core 7 251E is a desktop part built for sustained multi-core workloads. The benchmark database shows that the AMD chip has a substantial body of test results, while the Intel chip currently has no recorded benchmark scores, so direct comparisons rely on architectural and specification differences rather than measured performance data.

The Verdict

The AMD Ryzen AI 5 330 is the choice for mobile systems where power draw and integrated graphics matter. Its 28 TDP, 4 nm TSMC process, and Radeon 820M graphics make it suitable for compact laptops that need balanced single-thread and multi-thread performance without high cooling demands. The database places it at the 73rd percentile among all CPUs, with an average benchmark score of 18811, which puts it ahead of several established desktop and server parts. For instance, it scores 0.4% higher than the Intel Core i7-1355U, 0.6% higher than the AMD EPYC 7643, and 0.7% higher than the Intel Core i5-12400. It trails the AMD EPYC 7773X by 0.9%. These numbers indicate that the Ryzen AI 5 330 delivers competitive performance for its class, despite having only 4 cores and 8 threads.

The Intel Core 7 251E, by contrast, targets desktop builds that need many cores and threads. It has 24 cores and 32 threads, a 65 TDP, and a 5.60 GHz boost clock. Its 36 MB shared L3 cache and support for DDR4 and DDR5 memory give it flexibility for workstation-style tasks. The database shows no benchmark scores for this part, and its percentile is 50 with an average benchmark score of 0, meaning no recorded performance data exists yet. The launch MSRP is $384. The Core 7 251E is the right pick for users who prioritize core count and memory capacity over power efficiency, provided they have a desktop platform that can handle its higher thermal envelope.

The data does not support a direct head-to-head winner because the Intel chip lacks benchmark entries. Instead, the verdict is situational. The Ryzen AI 5 330 wins on portability and measured performance per watt, while the Core 7 251E wins on raw core count, thread count, and platform flexibility. Buyers should choose based on form factor and workload requirements, not on direct benchmark comparisons that do not exist in the database.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 5 330 uses the Zen 5 architecture, with the codename Krackan Point 2 and a generation label of Ryzen AI 300 (Zen 5 / Zen 5c). It is built on a 4 nm process at TSMC. The Intel Core 7 251E uses the codename Bartlett Lake and is labeled Core 7 (Bartlett Lake), built on a 10 nm process at Intel. The process node difference is significant: the AMD chip uses a more advanced 4 nm node, while the Intel chip uses a 10 nm node. This affects power efficiency and transistor density, though the database does not provide transistor counts for either part.

The core configurations diverge sharply. The Ryzen AI 5 330 has 4 cores and 8 threads, with a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The Core 7 251E has 24 cores and 32 threads, with a base clock of 2.10 GHz and a boost clock of 5.60 GHz. The Intel part has a higher boost clock and far more cores, but it also has a higher TDP of 65 W compared to 28 W for the AMD part. The AMD chip uses a dual-core cluster design based on Zen 5 and Zen 5c cores, which the generation field indicates, though the database does not specify how many cores are in each cluster.

Cache hierarchies also differ. Both have 80 KB L1 cache per core. The AMD chip has 1 MB L2 per core and 4 MB L3 cache. The Intel chip has 2 MB L2 per core and 36 MB shared L3 cache. The Intel part has a much larger L3 cache, which can benefit multi-threaded workloads that share data. The AMD part has a smaller L3 but relies on its newer process and architecture for efficiency.

Integrated graphics differ as well. The Ryzen AI 5 330 includes Radeon 820M graphics, while the Core 7 251E includes UHD Graphics 770. The database does not provide performance scores for either iGPU, so any comparison is qualitative. The AMD part is designed for mobile use, so its iGPU is likely optimized for low power. The Intel part is a desktop chip, so its iGPU may be less critical for users with discrete graphics cards.

Memory support separates the two. The AMD chip supports DDR5 and LPDDR5X, while the Intel chip supports DDR4 and DDR5. The Intel part also supports ECC memory, which the AMD part does not. Both use dual-channel memory buses with 89.6 GB/s bandwidth. PCIe support differs: the AMD chip uses Gen 4 with 14 lanes (CPU only), while the Intel chip uses Gen 5 with 16 lanes (CPU only). The Intel part has a newer PCIe standard and more lanes.

Head-to-Head Benchmarks

The database does not contain any head-to-head benchmark entries for these two processors. The field for head-to-head benchmarks is empty, and the win counts for both are zero. The Intel Core 7 251E has no individual benchmark results at all. The AMD Ryzen AI 5 330, however, has a full suite of benchmark scores that define its performance profile.

The AMD Ryzen AI 5 330 scores 1191 in Cinebench R15 multi-core and 199.9 in single-core. In Cinebench R23, it scores 7840 multi-core and 1812 single-core. Passmark tests show a multi-thread score of 12797, a single-thread score of 3515 (recorded twice), and a physics score of 705. Data compression reaches 152012, data encryption reaches 7251, extended instructions reach 11124, find prime numbers reaches 42, floating point math reaches 26196, integer math reaches 37771, and random string sorting reaches 16188.

These scores place the AMD chip at the 73rd percentile among all CPUs. Its nearest rivals in the database include the Intel Core i7-1355U with an average score of 18730, which is 0.4% lower than the AMD part. The AMD EPYC 7643 scores 18697, which is 0.6% lower. The Intel Core i5-12400 scores 18683, which is 0.7% lower. The AMD EPYC 7773X scores 18979, which is 0.9% higher than the Ryzen AI 5 330. These comparisons show that the mobile AMD part performs within a narrow band of several desktop and server processors, which is notable given its low TDP.

Because the Intel Core 7 251E has no scores, the database cannot confirm how it would perform in the same tests. The available data only describes its specifications. Any statement about its benchmark performance would be speculative, so the analysis must rely on architectural differences instead.

Where Each One Wins

The AMD Ryzen AI 5 330 wins in scenarios that value power efficiency and integrated graphics. Its 28 W TDP and 4 nm process make it suitable for laptops and other mobile devices where heat and battery life are primary concerns. The Radeon 820M iGPU provides basic graphics capability without a discrete card. The database shows that this chip can hold its own against desktop-class rivals in average benchmark score, sitting between the Intel Core i5-12400 and the AMD EPYC 7773X. The single-thread score of 3515 and the Cinebench R23 single-core score of 1812 indicate strong per-core performance, which helps in everyday tasks and lightly threaded applications. The mobile segment designation confirms that this is not a desktop replacement part, but rather a balanced mobile processor.

The Intel Core 7 251E wins in scenarios that require maximum core and thread counts. With 24 cores and 32 threads, it can handle highly parallel workloads such as video rendering, scientific simulations, or server-style tasks. The 36 MB shared L3 cache and support for ECC memory make it suitable for reliability-focused systems. The PCIe Gen 5 support with 16 lanes offers higher bandwidth for modern GPUs and storage devices. The 65 W TDP suggests it needs a robust cooling solution, but the desktop segment and Socket 1700 platform allow for that. The launch MSRP of $384 positions it as a higher-tier desktop processor. The larger die size of 257 mm² and the 10 nm process indicate a more complex silicon design, though the database does not provide transistor counts to quantify that complexity.

The AMD chip wins on portability and measured performance efficiency. The Intel chip wins on raw core count, memory flexibility, and platform expansion. The database has no head-to-head results to compare them directly, so the choice comes down to workload and system form factor. The AMD Ryzen AI 5 330 is the better fit for a thin laptop with modest cooling. The Intel Core 7 251E is the better fit for a desktop workstation that needs many cores and ECC memory support. Each processor serves a distinct market segment, and the recorded data supports that separation without indicating a clear overall winner.
