AMD Ryzen AI 7 450G vs Intel Core Ultra 5 225F Comparison

Head-to-Head Benchmarks

The benchmark data splits these two desktop processors into clearly contrasting strengths. The AMD Ryzen AI 7 450G wins 4 of the 11 head-to-head tests, while the Intel Core Ultra 5 225F takes the remaining 7. The most decisive AMD victory comes in integer math, where it scores 99,732 against Intel's 66,417, a 50.2% advantage. That is the largest margin in either direction across the entire comparison. Data compression also falls firmly to AMD: 402,831 versus 310,843, a 29.6% lead. Random string sorting goes AMD's way at 42,663 versus 37,325, a 14.3% edge, and extended instructions barely favor AMD at 28,223 versus 28,027, or 0.7%.

Intel's biggest counter is prime number finding, where it posts 352 versus AMD's 87, a 75.3% difference. Floating-point math is another clear Intel win: 92,554 versus 63,683, a 31.2% gap. Physics simulation follows suit, with Intel at 2,430 against AMD's 1,440, a 40.7% lead. Data encryption also favors Intel, 22,648 versus 18,937, a 16.4% advantage. The multithread score is nearly tied, Intel at 31,004 and AMD at 30,422, a 1.9% margin. Single-thread performance is similarly close, Intel at 4,397 versus AMD's 4,309, a 2% difference. The overall benchmark averages reflect this split: AMD's average benchmark score is 63,331, while Intel's is 37,313; however, those averages include different test suites, so the head-to-head deltas carry more analytical weight.

Where Each One Wins

For workloads that depend on integer throughput, compression, and sorting, the AMD Ryzen AI 7 450G is the stronger part. The 50.2% integer math lead and the 29.6% compression advantage indicate that database operations, archive handling, and general office-style integer workloads will run faster on the AMD chip. The 14.3% sorting win reinforces this pattern, suggesting that text processing and list manipulation tasks favor AMD as well.

The Intel Core Ultra 5 225F dominates compute-heavy floating-point and specialized scalar workloads. The 75.3% prime number advantage is enormous and points to strong performance in single-threaded integer loops that rely on branch-heavy algorithms. The 31.2% floating-point win means scientific simulations, 3D rendering calculations, and engineering software that uses FP math will benefit from Intel. The 40.7% physics score gap further confirms that simulation and rigid-body dynamics workloads prefer Intel. Encryption also leans Intel by 16.4%, which matters for VPN, secure file transfer, and database encryption tasks. The multithread and single-thread scores are effectively a tie, so neither chip has a meaningful general-purpose throughput advantage; the deciding factor is workload type, not thread count.

Architecture Differences

The two processors use fundamentally different designs. AMD's Ryzen AI 7 450G is built on the Gorgon Point codename with a hybrid Zen 5 and Zen 5c core arrangement. It has 8 cores and 16 threads, meaning simultaneous multithreading is enabled. The base clock is 2.00 GHz with a boost of 5.10 GHz. Intel's Core Ultra 5 225F uses Arrow Lake-S with 10 cores and 10 threads, so no hyper-threading is present. Its base clock is 3.30 GHz and boost is 4.90 GHz. Despite Intel having more physical cores, the thread count is equal at 16 versus 10, which explains why multithread scores are close.

The process nodes differ: AMD uses a 4 nm TSMC process, while Intel uses a 3 nm TSMC process. Die sizes also vary, with AMD at 195 mm² and Intel at 243 mm². Intel lists 17,800 million transistors, while AMD's transistor count is not recorded in the database. Cache hierarchies are notably different. AMD provides 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, 3 MB of L2 per core, and 20 MB of shared L3. Intel's larger L3 cache likely contributes to its single-thread and floating-point advantages.

Memory support also differs. AMD supports both DDR5 and LPDDR5X with dual-channel memory and a bandwidth of 89.6 GB/s, plus ECC memory support. Intel supports only DDR5, also dual-channel, but with higher bandwidth at 102.4 GB/s and no ECC support. PCIe connectivity is another split: AMD offers Gen 4 with 12 CPU lanes, while Intel offers Gen 5 with 20 CPU lanes. Integrated graphics are present on AMD (Radeon 860M) but absent on Intel (N/A). AMD's multiplier is unlocked for overclocking, while Intel's is locked. Intel has a launch MSRP of $231; AMD has no recorded launch MSRP.

The Verdict

The data points to a clear workload-based choice. The AMD Ryzen AI 7 450G is the pick for integer-heavy, compression-heavy, and sorting-heavy applications. Its 50.2% integer math lead and 29.6% compression advantage are decisive, and its 16 threads match Intel's effective multithread throughput despite having fewer physical cores. The presence of integrated graphics and ECC memory support also makes it suitable for systems where a discrete GPU is not required, and where memory integrity matters. The unlocked multiplier adds flexibility for users who can adjust clocks, though the database does not record overclocking test results.

The Intel Core Ultra 5 225F is the stronger choice for floating-point math, physics simulation, prime number finding, and encryption. Its 75.3% prime number lead and 40.7% physics advantage are substantial, and the 31.2% floating-point win covers many scientific and rendering workloads. The 20 MB L3 cache and higher memory bandwidth (102.4 GB/s) support this pattern. Intel also delivers a slight single-thread edge (2%) and a marginal multithread win (1.9%), so for general desktop use where workloads mix integer and floating-point tasks, Intel edges ahead overall in the head-to-head count. The lack of integrated graphics means a discrete GPU is mandatory, which is a practical consideration but not a benchmark score. For users who prioritize FP-heavy simulation, encryption, or prime number crunching, Intel is the data-supported choice. For users who prioritize integer throughput, compression, and sorting, AMD is the data-supported choice.
