AMD Ryzen AI 7 PRO 450 vs Intel Core Ultra 7 266V Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between the two processors, with the AMD Ryzen AI 7 PRO 450 taking 9 of the 15 head-to-head benchmarks, while the Intel Core Ultra 7 266V wins 6. The largest margin belongs to AMD in integer math, where the Ryzen AI 7 PRO 450 scores 86227 against Intel's 41558, a delta of 107.5%. That is more than double the throughput, and it reflects the AMD part's 16 threads versus the Intel part's 8 threads. Data compression follows a similar pattern, with the AMD chip scoring 294298 versus 187050, a 57.3% advantage. Random string sorting also favors AMD, at 32344 versus 22905, a 41.2% lead.

Multithreaded workloads generally favor the AMD processor. In Cinebench R15 multi-core, the Ryzen AI 7 PRO 450 scores 2457 against the Intel Core Ultra 7 266V's 1667, a 47.4% advantage. PassMark multithread shows a 27.3% lead for AMD, 24779 versus 19461. Extended instructions, which often track AVX and similar workloads, show AMD ahead by 30.4%, 20778 versus 15928. Data encryption is closer, with AMD at 14925 versus 13822, an 8% edge.

The Intel Core Ultra 7 266V wins in several single-thread and light-load tests. Cinebench R23 single-core shows Intel at 2335 versus AMD's 2010, a 13.9% lead. Cinebench R15 single-core is narrower, Intel at 235 versus AMD's 220, a 6.4% margin. In Cinebench R23 multi-core, Intel actually wins despite having half the threads, scoring 16544 versus 16054, a 3% lead. That is notable because it indicates the Intel chip's single-core efficiency carries over to lightly threaded multi-core scenarios.

PassMark find prime numbers is a decisive Intel win, 191 versus 84, a 56% margin. Floating point math also favors Intel, 56923 versus 52971, a 6.9% lead. PassMark physics shows Intel ahead at 1608 versus 1337, a 16.9% margin. The single-thread PassMark scores are nearly identical, with AMD at 3955 and Intel at 3943, a 0.3% difference that technically goes to AMD.

Architecture Differences

The two processors diverge sharply in core topology and thread support. The AMD Ryzen AI 7 PRO 450 uses the Zen 5 architecture, with a codename of Gorgon Point, and belongs to the Ryzen AI PRO 400 generation. It has 8 cores and 16 threads, meaning simultaneous multithreading is enabled. The Intel Core Ultra 7 266V is built on Lunar Lake, part of the Core Ultra Series 2, and also has 8 cores but only 8 threads, with no SMT. That difference explains the large multithreaded gaps in integer math and data compression.

Cache hierarchies are distinct. The AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. The Intel part has 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. Intel's larger cache per core helps its single-thread performance, which the benchmark scores confirm. The process nodes also differ: AMD uses TSMC's 4 nm process, while Intel uses TSMC's 3 nm process. That smaller node likely contributes to Intel's lower power draw.

Memory bandwidth is another differentiator. The AMD processor supports DDR5 and LPDDR5X with dual-channel memory, delivering 89.6 GB/s. The Intel chip supports LPDDR5X (dependent on motherboard) with dual-channel memory, delivering 136.5 GB/s, which is roughly 52% higher. That bandwidth advantage helps the Intel chip in memory-sensitive tasks like prime number finding and floating point math. AMD supports ECC memory, while Intel does not. PCIe lanes also differ: AMD offers Gen 4 with 16 lanes (CPU only), while Intel offers Gen 5 with 4 lanes (CPU only). The integrated graphics are both present but different: AMD has the Radeon 860M, Intel has the Arc 140V.

Power envelopes are significantly different. The AMD Ryzen AI 7 PRO 450 has a TDP of 28 watts, while the Intel Core Ultra 7 266V has a TDP of 17 watts. That lower TDP, combined with the 3 nm process, allows Intel to achieve competitive single-core scores while drawing less power in the same thermal class. The AMD part has a base clock of 2.00 GHz and a boost clock of 5.10 GHz; the Intel part has a base clock of 2.20 GHz and a boost clock of 5.00 GHz. Intel starts higher but boosts slightly lower.

The Verdict

The data indicates that the AMD Ryzen AI 7 PRO 450 is the stronger multi-threaded processor for workloads that scale with thread count, especially integer-heavy tasks, data compression, and random string sorting. Its 16 threads deliver a 107.5% lead in integer math and a 57.3% lead in data compression over the Intel Core Ultra 7 266V. For users running parallel workloads such as compilation, data processing, or encryption, the AMD part is clearly ahead.

The Intel Core Ultra 7 266V wins in single-thread performance, with a 13.9% lead in Cinebench R23 single-core and a 6.4% lead in Cinebench R15 single-core. It also wins in prime number finding, floating point math, physics, and, surprisingly, Cinebench R23 multi-core, despite having half the threads. That suggests the Intel chip is more efficient per thread and better suited for lightly threaded applications, or workloads that depend on cache and memory bandwidth rather than raw thread count.

The overall average benchmark score reflects this split. The AMD Ryzen AI 7 PRO 450 has an average score of 37093, placing it at the 85th percentile among all CPUs. The Intel Core Ultra 7 266V has an average score of 23297, at the 76th percentile. The AMD part's nearest rival is the Intel Core i9-12900T with an average score of 37112, a delta of -0.1%. The Intel part's nearest rival is the AMD Ryzen 7 5800H with an average score of 23277, a delta of 0.1%. Both chips sit close to their direct competitors.

For a mobile platform where multi-threaded throughput is the priority, the AMD Ryzen AI 7 PRO 450 is the choice. For a platform where single-thread responsiveness and lower power draw matter more, the Intel Core Ultra 7 266V is the better fit, provided the workload does not rely on many threads.
