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

Head-to-Head Benchmarks

The recorded head-to-head data is heavily one-sided. Out of 15 shared benchmark comparisons, the Intel Core Ultra 5 235T claims 14 wins, while the AMD Ryzen AI 7 PRO 450 takes only one. The single AMD victory comes in PassMark integer math, where the Ryzen scores 86,227 against Intel's 84,244, a margin of 2.4%. That is a narrow lead, but it suggests the Zen 5 cores handle integer workloads with slightly better efficiency per clock in that specific test.

Every other comparison favors Intel, often by substantial margins. In Cinebench R23 multi-core, the Intel part scores 26,232 versus AMD's 16,054, a delta of -38.8% from AMD's perspective. That is a massive gap in sustained multi-threaded rendering. The single-core Cinebench R23 result is even more lopsided: Intel reaches 3,703 while AMD manages 2,010, a -45.7% deficit. The pattern holds in Cinebench R15 as well, where Intel wins multi-core 2,644 to 2,457 (-7.1%) and single-core 373 to 220 (-41%). The single-core R15 delta is particularly striking, nearly double the AMD score.

PassMark results follow the same trajectory. The floating-point math test shows Intel at 106,546 against AMD's 52,971, a -50.3% difference. Prime number finding is even more dramatic: Intel scores 318, AMD scores 84, a -73.6% gap. That test often reflects branch prediction and integer throughput, and the Intel architecture is clearly far ahead here. Data encryption also favors Intel heavily, 23,457 to 14,925 (-36.4%). Extended instructions show a smaller but still clear Intel advantage, 23,212 to 20,778 (-10.5%).

The closest overall contest outside integer math is data compression. Intel edges AMD 295,100 to 294,298, a -0.3% difference that is nearly a tie. Random string sorting shows Intel ahead by 8.6% (35,377 to 32,344). PassMark multi-thread gives Intel 30,918 versus AMD's 24,779 (-19.9%), while PassMark single-thread shows Intel at 4,339 against AMD's 3,955 (-8.8%). Physics simulation in PassMark also goes Intel's way, 2,157 to 1,337 (-38%).

These numbers indicate a consistent architectural advantage for the Intel part across rendering, cryptography, floating-point, and prime-number workloads. The AMD chip's only win is narrow, and its losses range from nearly negligible to three-quarters of its rival's score. The average benchmark score in the database reflects this: Intel sits at 38,561, AMD at 37,093, a difference of about 1,468 points. Intel also holds a higher percentile ranking at 86 versus AMD's 85, although both are within the top tier of all CPUs tracked.

The Verdict

The data points to two very different products. The Intel Core Ultra 5 235T is the clear performance leader in almost every measured category. It delivers higher multi-core and single-core scores in both Cinebench R15 and R23, doubles or nearly doubles AMD's floating-point throughput, and dominates prime number and encryption tests. For users prioritizing raw compute, rendering, or heavy mathematical workloads, the recorded benchmarks leave little ambiguity: the Intel part is faster.

The AMD Ryzen AI 7 PRO 450 does have one advantage in integer math, but that single win does not offset the 14 losses. However, the AMD chip also carries a much lower TDP of 28 watts versus Intel's 65 watts, and it is designed for a mobile socket (FP8) while Intel targets desktop (Socket 1851). The database does not include power consumption measurements, so no efficiency conclusion can be drawn from numbers alone, but the TDP classification suggests AMD targets a thinner, lower-power form factor. The Intel part's launch MSRP is $247, and it is a desktop chip with a higher power envelope.

A user choosing between these two should consider the platform context. The AMD part belongs to a mobile AI PRO series, with integrated Radeon 860M graphics and support for LPDDR5X memory. The Intel part is a desktop chip with Arc Xe-LPG Graphics 24EU and DDR5 support. If the workload is heavy multi-threaded compute, the Intel chip wins decisively. If the system must fit a low-power mobile chassis, the AMD chip is the only one of the two designed for that socket, and its performance, while lower, is still competitive in integer tasks and data compression.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen AI 7 PRO 450 has 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel Core Ultra 5 235T has 14 cores and 14 threads, with a base clock of 2.20 GHz and a boost clock of 5.00 GHz. Intel has more cores but no hyper-threading, so its thread count equals its core count. AMD has fewer cores but double the threads, giving it 16 threads total.

Cache configurations diverge sharply. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. That is a substantial difference in L3: Intel has three times the total L3 capacity.

Memory support also differs. AMD supports both DDR5 and LPDDR5X, while Intel supports only DDR5. Both use a dual-channel memory bus. Memory bandwidth is higher for Intel at 102.4 GB/s, compared to AMD's 89.6 GB/s.

The TDP classification is very different: AMD is rated at 28 watts, Intel at 65 watts. The sockets are incompatible: AMD uses Socket FP8, Intel uses Socket 1851. PCIe support also differs, with AMD offering Gen 4 with 16 lanes (CPU only) and Intel offering Gen 5 with 20 lanes (CPU only). The integrated graphics are different as well: AMD uses Radeon 860M, Intel uses Arc Xe-LPG Graphics 24EU. The Intel chip has a launch MSRP of $247; AMD has no listed launch MSRP.

Architecture Differences

The AMD Ryzen AI 7 PRO 450 is built on Zen 5 architecture, codenamed Gorgon Point, and belongs to the Ryzen AI PRO 400 generation. Its process node is 4 nm, fabricated by TSMC, with a die size of 195 mm². The Intel Core Ultra 5 235T uses Arrow Lake architecture, codenamed Arrow Lake-S, and belongs to the Core Ultra Series 2. Its process node is 3 nm, also fabricated by TSMC, with a die size of 243 mm² and a transistor count of 17,800 million.

The core design philosophies differ. AMD's Zen 5 architecture relies on simultaneous multithreading to double thread count from 8 to 16. Intel's Arrow Lake architecture does not use hyper-threading, so its 14 cores map directly to 14 threads. This means AMD's per-thread resources are more numerous relative to its core count, but Intel's total core count is higher.

Cache hierarchy reflects different design goals. AMD uses a smaller per-core L1 (80 KB) and L2 (1 MB), with a modest 8 MB L3. Intel uses larger per-core L1 (192 KB) and L2 (3 MB), plus a 24 MB shared L3. The larger L3 likely helps Intel in multi-threaded workloads that reuse data across cores.

PCIe generation is another differentiator. Intel supports Gen 5 with 20 lanes, which is newer and has higher bandwidth than AMD's Gen 4 with 16 lanes. Memory bandwidth is also higher on Intel (102.4 GB/s versus 89.6 GB/s). The Intel chip does not support ECC memory, while AMD does, which may matter for certain workstation or server-style use cases.

The process node difference is notable: 3 nm for Intel versus 4 nm for AMD. Both are TSMC nodes, but the smaller node typically allows for more transistors in a given area or lower power for the same frequency. The Intel die is larger at 243 mm² versus AMD's 195 mm², and it packs 17,800 million transistors, while AMD's transistor count is not recorded.

Where Each One Wins

The Intel Core Ultra 5 235T wins across the vast majority of workloads in the database. It leads in all Cinebench tests, both multi-core and single-core, with margins ranging from 7.1% to 45.7%. It also wins in PassMark's floating-point math, prime number finding, data encryption, extended instructions, multi-thread, single-thread, physics, random string sorting, and data compression. The only PassMark test where it loses is integer math, where AMD takes 86,227 to Intel's 84,244.

For rendering tasks like Cinebench R23, the Intel chip's 26,232 multi-core score is a clear win. For single-threaded responsiveness, the 3,703 single-core score also favors Intel. For cryptography, the 23,457 encryption score is 36.4% ahead. For scientific or engineering workloads that rely on floating-point math, Intel's 106,546 score is double AMD's. Prime number finding, which stresses integer and branch logic, shows Intel at 318 versus AMD's 84, a 73.6% advantage.

The AMD Ryzen AI 7 PRO 450 wins only in PassMark integer math, and by a slim 2.4% margin. That suggests it has a slight edge in pure integer arithmetic per clock, but this does not translate into wins in related tests like prime number finding or integer-heavy compression, where Intel leads. AMD also comes very close in data compression, trailing by only 0.3%, which is effectively a tie.

From a platform perspective, the AMD chip is the only one with ECC memory support and LPDDR5X compatibility. Its 28-watt TDP is less than half of Intel's 65 watts, making it more suited to thin-and-light mobile systems. The Intel chip is a desktop part with a larger power budget, more L3 cache, and PCIe Gen 5 support. The recorded performance data heavily favors Intel for compute-intensive tasks, while AMD's advantages lie in lower power classification, ECC support, and a narrower loss in integer math and compression.
