AMD Ryzen AI 7 450 vs Intel Core Ultra 5 235A Comparison

Where Each One Wins

The head-to-head benchmark data is unambiguous: the Intel Core Ultra 5 235A wins all 15 recorded comparisons against the AMD Ryzen AI 7 450. There are no benchmark categories where the AMD processor takes a victory, which makes the use-case split a matter of degree rather than direction. The Intel part dominates across rendering, math workloads, encryption, compression, and single-threaded tasks.

The largest gaps appear in compute-heavy workloads. In Cinebench R23 multi-core, the Intel chip scores 32633 against the AMD's 18316, a 43.9% deficit for the AMD part. The single-core gap is even more pronounced: Intel's 4607 in Cinebench R23 single-core versus AMD's 2038 represents a 55.8% lead for Intel. This pattern repeats across PassMark tests, where Intel leads by 77.3% in find prime numbers, 54.2% in floating point math, and 46.1% in data encryption.

The narrowest margin is in PassMark integer math, where Intel scores 88626 against AMD's 88531, a lead of just 0.1%. That near-tie indicates the two processors are essentially equivalent in basic integer arithmetic throughput. The PassMark single-thread test shows a 14.4% Intel advantage (4557 versus 3901), which is more modest than the Cinebench single-core results suggest. Data compression shows a 19.8% Intel lead (393800 versus 315906), while random string sorting shows a 28% gap (49489 versus 35648).

For workloads that depend on heavy parallel throughput, such as video rendering or scientific simulation, the Intel Core Ultra 5 235A is the clear choice based on the recorded measurements. For workloads that are integer-bound and less dependent on cache hierarchy or SIMD width, the AMD Ryzen AI 7 450 is much closer, though still behind. The database shows no scenario where the AMD chip wins outright, so any selection between these two must account for the consistent, if variable, Intel advantage.

Architecture Differences

The two processors come from different design philosophies and target different market segments. The AMD Ryzen AI 7 450 is a mobile processor built for AMD Socket FP8, using the Zen 5 architecture under the Gorgon Point codename. It belongs to the Ryzen AI 400 generation, which mixes Zen 5 and Zen 5c cores. The manufacturing process is a 4 nm node from TSMC, with a die size of 195 mm². The Intel Core Ultra 5 235A is a desktop part on Intel Socket 1851, using the Arrow Lake architecture under the Arrow Lake-S codename. It belongs to the Ultra 5 generation and uses a 3 nm TSMC process with a die size of 243 mm². Intel lists 17,800 million transistors for this chip.

Core counts differ substantially. The AMD part has 8 cores and 16 threads, while the Intel part has 14 cores and 14 threads. Intel does not use simultaneous multithreading here, so its thread count equals its core count. AMD's base clock is 2.00 GHz with a boost clock of 5.10 GHz, while Intel's base clock is 3.40 GHz with a boost clock of 5.00 GHz. The AMD chip has a 28 watt TDP, the Intel chip a 65 watt TDP.

Cache hierarchies are structured differently. AMD uses 80 KB L1 per core, 1 MB L2 per core, and 8 MB of L3. Intel uses 192 KB L1 per core, 3 MB L2 per core, and 24 MB of shared L3. That larger L3 cache likely contributes to Intel's advantage in data compression and random string sorting, which benefit from more resident working sets. Memory support also differs: AMD supports DDR5 and LPDDR5X with dual-channel access and 89.6 GB/s bandwidth, while Intel supports only DDR5 with dual-channel access and 102.4 GB/s bandwidth. AMD includes ECC memory support, Intel does not.

PCIe connectivity favors Intel with Gen 5 and 20 lanes (CPU only), versus AMD's Gen 4 with 16 lanes (CPU only). Integrated graphics differ as well: AMD uses Radeon 860M, Intel uses Arc Xe-LPG Graphics 24EU. The AMD part is an active mobile product with a release date in January 2026, while the Intel part is an active desktop product released in July 2025. Intel has a launch MSRP of $269. AMD has no recorded launch MSRP. Neither processor has an unlocked multiplier.

The process node difference, 4 nm versus 3 nm, does not translate into a performance advantage for AMD in these benchmarks. Despite the smaller node for Intel, the higher TDP and larger cache appear to drive the performance gap. The AMD chip's lower TDP suggests it is designed for power-constrained mobile systems, while Intel's higher TDP aligns with desktop use where thermal headroom is more available.

The Verdict

The recorded data points to a straightforward conclusion: the Intel Core Ultra 5 235A outperforms the AMD Ryzen AI 7 450 in every measured benchmark. The average benchmark score for Intel is 48201, which places it in the 90th percentile of all CPUs. AMD's average is 39485, placing it in the 87th percentile. The delta between the two is roughly 22% in favor of Intel based on those averages.

For desktop users who need maximum multi-threaded throughput, the Intel part is the correct choice. Cinebench R23 multi-core results show a 43.9% advantage, and PassMark multi-thread shows 38392 versus 26350, a 31.4% lead. For users who prioritize single-thread responsiveness, Intel also leads, with a 55.8% advantage in Cinebench R23 single-core and 14.4% in PassMark single-thread.

For mobile or power-sensitive systems, the AMD Ryzen AI 7 450 offers a 28 watt TDP and 8 cores with 16 threads, which delivers respectable performance in a lower power envelope. Its integer math score is nearly identical to Intel's, so integer-heavy workloads will see minimal difference. The AMD part also supports ECC memory and LPDDR5X, features that Intel lacks. However, the performance gap is too large to recommend AMD on performance alone.

Nearest rival data provides context. AMD's closest rivals include the AMD Ryzen 7 PRO 8840HS with an average score of 39603 (0.3% above the Ryzen AI 7 450) and the AMD Ryzen 7 9800X3D at 39768 (0.7% above). Intel's closest rivals include the AMD Ryzen AI Max PRO 380 at 48171 (0.1% below) and the Intel Core Ultra 5 245HX at 48287 (0.2% above). This indicates the Ryzen AI 7 450 sits near the top of its own performance tier, and the Core Ultra 5 235A sits similarly within its tier, but those tiers are separated by roughly 22%.

The verdict is that the Intel Core Ultra 5 235A is the superior processor for benchmark-driven workloads, with the AMD Ryzen AI 7 450 serving as a lower-power alternative that trades significant performance for a smaller thermal footprint and mobile compatibility.

Head-to-Head Benchmarks

The most decisive Intel win comes in PassMark find prime numbers, where Intel scores 392 against AMD's 89, a 77.3% advantage. This test is highly sensitive to clock speed and integer execution efficiency, and the data shows Intel's architecture executing this workload far more effectively. Cinebench R23 single-core shows a 55.8% Intel lead (4607 versus 2038), and Cinebench R15 single-core shows a 53.7% lead (464 versus 215). These single-core gaps are larger than the PassMark single-thread gap of 14.4% (4557 versus 3901), which suggests the Cinebench workload benefits more from Intel's per-core resources.

Floating point math heavily favors Intel, with a score of 118778 versus AMD's 54447, a 54.2% lead. Data encryption shows Intel at 30136 versus AMD's 16247, a 46.1% advantage. Extended instructions tests show a 29.2% Intel lead (31625 versus 22400). Physics simulation shows Intel at 2437 versus AMD's 1578, a 35.2% advantage. Random string sorting shows a 28% Intel lead (49489 versus 35648).

Cinebench R15 multi-core shows Intel at 3289 versus AMD's 2713, a 17.5% lead. This is smaller than the Cinebench R23 multi-core gap of 43.9%, indicating that the R23 workload scales better with Intel's additional cores and larger cache. PassMark multi-thread shows a 31.4% Intel lead (38392 versus 26350). Data compression shows a 19.8% lead (393800 versus 315906).

The only near-tie is PassMark integer math, with Intel at 88626 and AMD at 88531. This result is remarkable given the architectural differences, and it suggests that basic integer arithmetic is not where Intel's advantages lie. All other workloads show Intel leading by double-digit percentages, with the exception of the 0.1% integer math margin.

The overall pattern is consistent: Intel wins every single head-to-head comparison, with margins ranging from negligible to dominant. The AMD Ryzen AI 7 450 delivers competitive integer throughput and lower power consumption, but the Intel Core Ultra 5 235A is faster across the board in the recorded benchmarks.
