AMD Ryzen AI 7 450G vs Intel Core i5-14400F Comparison

Head-to-Head Benchmarks

The recorded PassMark data shows a decisive overall victory for the AMD Ryzen AI 7 450G, which claims 10 of the 11 head-to-head comparisons against the Intel Core i5-14400F. The largest margin comes in extended instructions, where AMD leads by 41.6% (28,223 versus 19,937), a gap that indicates substantially stronger SIMD and cryptography-related throughput. Data compression also favors AMD heavily, with a 27.7% advantage (402,831 versus 315,521), while random string sorting shows a 30.5% lead (42,663 versus 32,680). These three workloads, all memory- and instruction-intensive, paint a picture of a processor that handles data manipulation tasks with notable efficiency.

Integer math is another significant win for AMD, delivering 99,732 against Intel's 81,524, a 22.3% margin. The multithread score follows the same trend: AMD posts 30,422 versus 25,470, or 19.4% higher. Single-thread performance also favors AMD, with 4,309 versus 3,701, a 16.4% lead in both recorded single-thread tests. Floating-point math is closer, with AMD ahead by only 3.9% (63,683 versus 61,319), and the prime number search is nearly identical, AMD edging out Intel by 1.2% (87 versus 86).

The sole Intel victory is in the physics test, where the Core i5-14400F scores 1,523 against AMD's 1,440, a 5.4% advantage. This is an interesting outlier given the overall pattern, and it suggests that the Intel architecture handles certain physics simulations more efficiently despite losing in most raw throughput measures. Data encryption is also an AMD win, but the margin is narrower at 11.7% (18,937 versus 16,949), indicating that both processors handle encryption workloads competently.

Looking at the broader benchmark averages, the Ryzen AI 7 450G records an average score of 63,331, placing it in the 93rd percentile of all CPUs in the database. The Core i5-14400F averages 32,279, which sits in the 83rd percentile. The nearest rivals for AMD, the Intel Core Ultra 7 265HX (63,173, a 0.2% delta) and the AMD Ryzen AI Max PRO 390 (63,765, a -0.7% delta), show that the Ryzen AI 7 450G is operating in a performance tier well above the Core i5. Intel's nearest competitors, the AMD Ryzen 7 PRO 8840U (32,233, a 0.1% delta) and the Intel Core i9-11900 (32,226, a 0.2% delta), confirm that the Core i5-14400F sits in a lower performance bracket entirely.

The Verdict

The data indicates that the AMD Ryzen AI 7 450G is the stronger processor in nearly every measured category. Its 93rd percentile ranking versus Intel's 83rd percentile is a clear summary of the performance gap. The 19.4% multithread lead and the 16.4% single-thread lead mean that AMD wins both in heavily threaded workloads and in tasks that depend on a single core's speed. The 22.3% integer math advantage and the 41.6% extended instructions advantage further solidify this position for computational workloads.

The Intel Core i5-14400F does hold one advantage in the physics test, and it matches AMD closely in prime number searching. However, these narrow wins do not offset the broad pattern of AMD dominance across nine other benchmarks. The average benchmark score difference, 63,331 versus 32,279, is substantial, nearly double. For anyone comparing these two based on recorded data alone, the Ryzen AI 7 450G is the higher-performing part in the vast majority of scenarios.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation built on Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process at TSMC, with a die size of 195 mm². The Intel Core i5-14400F, by contrast, uses the Raptor Lake architecture, specifically Raptor Lake-R, and belongs to the Core 14th Gen family with a Raptor Lake Refresh generation label. It is built on Intel's 10 nm process (a node designation that does not directly equate to physical dimensions) and has a die size of 215 mm², slightly larger than AMD's.

Core counts differ: AMD packs 8 cores and 16 threads, while Intel offers 10 cores and 16 threads. The base clocks also differ, with AMD at 2.00 GHz and Intel at 2.50 GHz, but AMD's boost clock reaches 5.10 GHz against Intel's 4.70 GHz. Cache hierarchies diverge as well. Both use an 80 KB L1 per core, but AMD allocates 1 MB of L2 per core while Intel provides 1.25 MB per core. The L3 cache is a major difference: AMD has 8 MB total, while Intel has 20 MB shared.

Memory support is another distinguishing factor. AMD supports DDR5 and LPDDR5X memory, while Intel supports DDR4 and DDR5. The memory bus is dual-channel for both, but AMD lists a memory bandwidth of 89.6 GB/s, a figure Intel does not report. Both support ECC memory, which is notable for workstation-type workloads. PCIe capabilities differ: AMD offers Gen 4 with 12 CPU lanes, while Intel offers Gen 5 with 16 CPU lanes, giving Intel a potential advantage in bandwidth for PCIe-connected devices.

The integrated graphics situation is starkly different. The Ryzen AI 7 450G includes a Radeon 860M iGPU, while the Core i5-14400F has no integrated graphics at all, listed as N/A. This means the AMD part can output to a display without a discrete GPU, while the Intel F-series part requires one. The AMD processor also has an unlocked multiplier, whereas Intel's is locked, meaning the AMD chip can be overclocked if the platform permits.

Specification Differences

Comparing the specification sheets side by side, the key differences are clear. The AMD Ryzen AI 7 450G uses 8 cores and 16 threads, while the Intel Core i5-14400F uses 10 cores and 16 threads. AMD's base clock is 2.00 GHz versus Intel's 2.50 GHz, but AMD's boost clock is 5.10 GHz versus Intel's 4.70 GHz. Both have a 65 W TDP, so power draw is nominally equal.

The sockets are incompatible: AMD uses AMD Socket AM5, while Intel uses Intel Socket 1700. The process nodes differ, 4 nm at TSMC for AMD versus 10 nm at Intel for the Core i5. Die size favors AMD at 195 mm² versus Intel's 215 mm². Cache configurations are distinct, with AMD at 1 MB L2 per core and 8 MB L3, while Intel has 1.25 MB L2 per core and 20 MB shared L3.

Memory support splits along platform lines: AMD accepts DDR5 and LPDDR5X, while Intel accepts DDR4 and DDR5. The recorded memory bandwidth of 89.6 GB/s applies only to AMD. PCIe generation and lane counts differ, with AMD at Gen 4 with 12 lanes and Intel at Gen 5 with 16 lanes. Integrated graphics exist only on the AMD side, with the Radeon 860M, while Intel has none. The multiplier is unlocked on AMD and locked on Intel. The launch MSRP for the Intel Core i5-14400F is $196; no launch MSRP is recorded for the AMD part. The release date for AMD is 2026-02-28, while Intel's is 2024-01-07, making the AMD part a newer design by roughly two years.

Where Each One Wins

The AMD Ryzen AI 7 450G is the clear winner for most computational tasks. Its 41.6% lead in extended instructions makes it the better choice for workloads that rely on SIMD operations, such as multimedia encoding and scientific calculations. The 27.7% advantage in data compression and the 30.5% lead in random string sorting point to strengths in database operations, file archiving, and text processing. The 22.3% integer math win suggests superiority in general-purpose arithmetic, while the 19.4% multithread advantage covers most multi-threaded applications, from rendering to compilation. The 16.4% single-thread lead also means that lightly threaded software, such as many older games and office applications, will run faster on the AMD part.

The Intel Core i5-14400F wins only the physics test, with a 5.4% margin. This suggests that certain physics simulation engines, which often involve specific floating-point patterns and branch behavior, operate slightly better on the Intel architecture. The prime number test is effectively a tie, with AMD at 87 and Intel at 86, so no meaningful advantage exists there. The Intel part also has a larger L3 cache, 20 MB versus 8 MB, which could benefit workloads with large working sets that fit in cache, although the recorded PassMark scores do not show a consistent advantage from this. The Gen 5 PCIe support with 16 lanes is another Intel advantage for users who need maximum bandwidth for storage or GPU connectivity, though this is a platform feature rather than a CPU performance metric.

The overall split is lopsided: AMD wins 10 benchmarks, Intel wins 1. The average benchmark score, the percentile ranking, and the head-to-head deltas all point in the same direction. The AMD Ryzen AI 7 450G is the higher-performing processor in the database's recorded measurements, and the Intel Core i5-14400F holds only a narrow niche in physics simulations. The data does not show any scenario where Intel's strengths in cache size or PCIe Gen 5 translate into benchmark wins beyond that single physics test.
