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

The AMD Ryzen AI 7 450G is a desktop processor built for Socket AM5, while the Intel Core Ultra 7 266V is a mobile chip on BGA 2833. The data shows a stark contrast in performance profile and market positioning, with the AMD part dominating most compute-heavy tasks and the Intel part showing specific strengths in prime number calculations and physics simulations.

Where Each One Wins

The AMD Ryzen AI 7 450G takes a decisive lead in 9 of the 11 recorded head-to-head benchmarks. Its most dominant victories come in integer math, where it scores 99,732 against Intel's 41,558, a 140% advantage. Data compression also heavily favors AMD: 402,831 versus 187,050, a 115.4% delta. These results indicate the AMD chip is substantially stronger for workloads that stress raw arithmetic throughput and memory compression routines.

The Intel Core Ultra 7 266V wins only two benchmarks, but they are notable. In the find prime numbers test, Intel scores 191 versus AMD's 87, a 54.5% lead. The physics benchmark also goes to Intel, with 1,608 points against AMD's 1,440, a 10.4% advantage. These wins suggest the Intel processor has an efficiency edge in certain single-thread-sensitive or specialized instruction patterns, despite its lower overall throughput.

The average benchmark score tells a similar story. AMD's average is 63,331, placing it in the 93rd percentile of all CPUs in the database. Intel's average is 23,297, landing in the 76th percentile. The AMD processor sits near the top of the database, with its nearest rivals all scoring within a narrow band: the Intel Core Ultra 7 265HX at 63,173, the Intel Core i7-13790F at 63,080, and the AMD Ryzen AI Max PRO 390 at 63,765. The Intel chip, by contrast, is surrounded by much older parts like the AMD Ryzen 7 5800H at 23,277 and the Intel Core i9-11900F at 23,254.

Architecture Differences

The two processors come from different design philosophies. AMD uses the Gorgon Point codename with a Zen 5 / Zen 5c hybrid core arrangement, fabricated on a 4 nm process at TSMC. Intel's Lunar Lake architecture uses a 3 nm TSMC node. Both have 8 physical cores, but AMD enables 16 threads through simultaneous multithreading, while Intel runs 8 threads with no SMT support. This thread count difference is a primary driver of the AMD chip's multithreaded performance advantage, where it scores 30,422 versus Intel's 19,461, a 56.3% delta.

Cache configurations differ significantly. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. Intel's larger per-core caches likely explain its win in the prime number test, where a tighter working set benefits from faster local storage. AMD's smaller L3 pool, however, does not hinder its performance in the broad benchmark suite.

Memory support also separates the two. AMD supports DDR5 and LPDDR5X with dual-channel memory and a recorded bandwidth of 89.6 GB/s. Intel supports LPDDR5X depending on motherboard configuration, also dual-channel, but with a higher bandwidth of 136.5 GB/s. The Intel part includes ECC memory support, while the AMD part does not. PCIe connectivity shows a similar split: AMD provides Gen 4 with 12 CPU lanes, Intel provides Gen 5 with 4 CPU lanes.

The integrated graphics differ as well. AMD pairs the CPU with Radeon 860M graphics, while Intel uses Arc 140V. Both are integrated solutions, but the database does not include graphics benchmarks for either. The AMD processor is unlocked for multiplier adjustment and has a 65 W TDP, while Intel's chip is locked and rated at 17 W, reflecting its mobile focus.

Head-to-Head Benchmarks

The largest margin of victory belongs to AMD in integer math. The 99,732 score against 41,558 represents a 140% delta, and this result alone explains why the AMD chip's average benchmark score is so much higher. Data compression follows closely, with AMD at 402,831 versus Intel's 187,050, a 115.4% delta. Random string sorting also shows a massive gap: AMD scores 42,663 against Intel's 22,905, an 86.3% advantage.

Extended instructions favor AMD at 28,223 versus 15,928, a 77.2% delta. The multithread test shows a 56.3% lead for AMD, which is consistent with the thread count difference. Data encryption goes to AMD at 18,937 versus 13,822, a 37% margin. Floating point math is closer, with AMD at 63,683 and Intel at 56,923, an 11.9% delta. Single-thread performance also goes to AMD, with 4,309 points against Intel's 3,943, a 9.3% advantage.

Intel's two wins are smaller in aggregate impact. The prime number test gives Intel a 54.5% advantage, but the absolute scores are low: 191 versus 87. The physics benchmark shows Intel ahead by 10.4%, with 1,608 points to AMD's 1,440. These wins demonstrate that Intel's architecture has specific strengths, but they do not offset the broad performance gap in the other nine tests.

The Verdict

The recorded data points to the AMD Ryzen AI 7 450G as the stronger processor for general and heavy compute tasks. Its 93rd percentile ranking, average score of 63,331, and 9 benchmark wins make it the clear choice for workloads involving integer math, compression, encryption, and multithreaded processing. The nearest rivals to AMD are all within 1% of its average score, confirming that it sits in a competitive performance tier.

The Intel Core Ultra 7 266V, with its 76th percentile ranking and average score of 23,297, is not in the same performance class. Its wins in prime number calculation and physics suggest it has niche strengths, likely tied to its larger per-core caches and efficient Lunar Lake architecture. The 17 W TDP also indicates a design aimed at power efficiency, which aligns with its mobile market segment and BGA socket.

The choice between the two depends on platform and workload priorities. The AMD chip requires Socket AM5 and a 65 W power envelope, but it delivers substantially higher throughput across most benchmarks. The Intel chip is a mobile part with a locked multiplier, lower power draw, and faster memory bandwidth, yet it lags in nearly every compute-heavy test. For users building a desktop system and prioritizing raw performance, the data supports the AMD processor. For a mobile or low-power system where the physics and prime number results matter, the Intel part has a narrow case, but the benchmark record shows AMD winning the vast majority of performance comparisons.
