AMD Ryzen AI 7 450G vs Intel Core i9-14900HX Comparison

Head-to-Head Benchmarks

The head-to-head data records 11 benchmark comparisons between the AMD Ryzen AI 7 450G and the Intel Core i9-14900HX. Intel takes 9 of those tests, while AMD wins 2. The margin of victory, however, is not uniform across the board.

The Intel Core i9-14900HX delivers its largest lead in the prime number calculation test, scoring 193 against AMD's 87, a delta of 54.9%. That is the single biggest percentage gap in the entire comparison. Floating point math also shows a substantial Intel advantage: 112,273 versus 63,683, a 43.3% difference. Data encryption follows a similar pattern, with Intel at 32,619 and AMD at 18,937, a 41.9% gap. Physics simulation results put Intel ahead by 45.4%, scoring 2,638 against 1,440.

The multithreaded PassMark score, which serves as a broad indicator of parallel workload capability, favors Intel by 30.5%. Intel records 43,778 while AMD manages 30,422. Integer math shows a 36.6% Intel lead, 157,375 to 99,732. Random string sorting goes to Intel by 29.9%, 60,861 to 42,663. Data compression shows a 25.4% Intel advantage, 539,965 to 402,831. The smallest Intel win comes in extended instructions, where the margin is 9.7%, 31,247 to 28,223.

AMD's two victories are in single-threaded performance. The PassMark single thread score shows AMD at 4,309 against Intel's 4,175, a 3.2% edge. The duplicate singlethread entry records the identical scores and the same 3.2% delta. These are narrow wins, but they are the only tests where the Ryzen AI 7 450G comes out on top.

Looking at the average benchmark scores, the AMD part posts 63,331 while Intel sits at 56,004. That places the AMD chip in the 93rd percentile of all CPUs in the database, versus the 91st percentile for Intel. The discrepancy between the head-to-head results and the average scores is striking. The average score is calculated across a broader set of tests, and the AMD chip's high average is reflected in its nearest rivals: the Intel Core Ultra 7 265HX is only 0.2% behind, the Intel Core i7-13790F is 0.4% behind, and the AMD Ryzen AI Max PRO 390 is 0.7% ahead. For Intel, the nearest rivals are the Intel Core 7 253PQE at 0.2% behind, the AMD Ryzen AI Max 390 at 0.5% ahead, and the AMD Ryzen AI 9 HX PRO 470 at 0.5% ahead.

The Verdict

The data separates these two processors by workload type more than by overall capability. The Intel Core i9-14900HX is the stronger choice for heavily threaded, compute-intensive tasks. Its 54.9% lead in prime number calculation, 43.3% lead in floating point math, and 41.9% lead in encryption all point to a processor that sustains high throughput across many cores. The 30.5% multithread advantage reinforces that pattern.

The AMD Ryzen AI 7 450G wins the single-thread contest, but only by 3.2%. That is a meaningful result for lightly threaded applications, yet the margin is modest compared to the double-digit gaps Intel posts elsewhere. The AMD chip also holds the higher average benchmark score in the database, 63,331 to 56,004, and the higher percentile ranking at 93 versus 91. That suggests the AMD processor performs more consistently across the full range of recorded tests, even though the specific head-to-head tests heavily favor Intel.

A user prioritizing parallel rendering, encryption, compression, or physics workloads would find the Intel part clearly superior based on these measurements. A user whose work relies on single-thread responsiveness would see a small but real advantage from the AMD chip. The average score data complicates a simple verdict, since the AMD chip's overall database standing is higher despite losing most head-to-head tests.

Architecture Differences

The two processors come from 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 by TSMC on a 4 nm process. The Intel Core i9-14900HX uses the Raptor Lake architecture, specifically Raptor Lake-HX Refresh, and is built on Intel's 10 nm process. The die sizes differ: AMD measures 195 mm², Intel measures 257 mm².

Core counts diverge sharply. AMD provides 8 cores and 16 threads. Intel provides 24 cores and 32 threads. That core advantage explains much of Intel's lead in multithreaded and parallel benchmarks. Clock speeds also favor Intel on paper: AMD has a 2.00 GHz base clock and 5.10 GHz boost clock, while Intel has a 2.20 GHz base and 5.80 GHz boost. The TDP figures are close, with AMD at 65 and Intel at 55, though these are nominal ratings rather than measured power draw.

Cache configurations differ in capacity and organization. Both use 80 KB of L1 per core. AMD provides 1 MB of L2 per core and 8 MB of L3. Intel provides 2 MB of L2 per core and 36 MB of shared L3. The larger Intel L3 pool is a significant structural difference that supports its performance in cache-sensitive workloads.

Memory support overlaps on DDR5 but diverges elsewhere. AMD supports DDR5 and LPDDR5X with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5 on a dual-channel bus, with no bandwidth figure recorded in the database. Both processors support ECC memory. PCIe connectivity differs by generation and lane count: AMD uses Gen 4 with 12 CPU lanes, Intel uses Gen 5 with 16 CPU lanes.

Integrated graphics also differ. AMD pairs the CPU with a Radeon 860M. Intel uses UHD Graphics 770. The AMD part targets the desktop segment on AMD Socket AM5, while Intel is a mobile part on Intel BGA 1964. Both have unlocked multipliers. AMD released on 2026-02-28, Intel on 2024-01-07. Both remain in active production.

Where Each One Wins

The Intel Core i9-14900HX wins in every heavily parallel workload recorded in the head-to-head set. Data compression, encryption, extended instructions, prime number calculation, floating point math, integer math, multithreaded performance, physics simulation, and random string sorting all go to Intel. The margins range from 9.7% in extended instructions to 54.9% in prime numbers. The 24-core, 32-thread configuration gives it a structural advantage in any test that scales with core count.

The AMD Ryzen AI 7 450G wins in single-threaded tests. The PassMark single thread score of 4,309 beats Intel's 4,175 by 3.2%. That is a narrow margin, but it is consistent across both recorded single-thread entries. The AMD chip also holds the higher average benchmark score in the database, 63,331 versus 56,004, and the higher percentile ranking at 93 versus 91. Its nearest rival, the Intel Core Ultra 7 265HX, sits just 0.2% behind, while the AMD Ryzen AI Max PRO 390 sits 0.7% ahead. Intel's nearest rival, the Intel Core 7 253PQE, is 0.2% behind, and the AMD Ryzen AI Max 390 is 0.5% ahead.

The use-case split is clear from the data. Workloads that demand many cores, such as rendering, encryption, compression, and physics, belong to Intel. Workloads that depend on single-thread latency, such as certain interactive applications, lean slightly toward AMD. The average score data suggests the AMD processor is more balanced across the full database test suite, even though the head-to-head results favor Intel in the majority of tests.
