AMD Ryzen AI 7 450G vs Intel Core 7 251E Comparison

AMD Ryzen AI 7 450G vs Intel Core 7 251E

Head-to-Head Benchmarks

The benchmark comparison between these two desktop processors is one-sided due to a critical data gap: the Intel Core 7 251E has no recorded benchmark scores in the database, while the AMD Ryzen AI 7 450G has a complete set of performance measurements. The AMD processor's average benchmark score is 63,331, placing it in the 93rd percentile of all CPUs tested. The Intel part, by contrast, holds a 50th percentile ranking with an average score of zero, indicating that no validated performance data exists for it in the current database. This absence of data means that every head-to-head comparison defaults to an AMD win by default, not by measured superiority, but by lack of competing information.

What the recorded data does show is how the AMD Ryzen AI 7 450G performs across individual workload categories. Its PassMark single-thread score of 4,309 indicates strong per-core performance, which is further underscored by a floating-point math score of 63,683 and an integer math score of 99,732. The processor delivers a multithread score of 30,422, which reflects its 8-core, 16-thread configuration working in parallel. Data compression tasks score 402,831, while encryption workloads reach 18,937, and extended instruction sets produce 28,223. Random string sorting, a memory-heavy operation, scores 42,663, and the physics simulation benchmark records 1,440. Prime number finding, often a test of raw arithmetic throughput, scores 87.

Because the Intel Core 7 251E lacks any benchmark entries, the database cannot provide a delta percentage between the two processors. In the absence of rival scores, the AMD chip's nearest rivals offer context: the Intel Core Ultra 7 265HX scores 63,173 with a 0.2 percent delta, the Intel Core i7-13790F scores 63,080 with a 0.4 percent delta, and the AMD Ryzen AI Max PRO 390 scores 63,765 with a negative 0.7 percent delta. These figures show that the Ryzen AI 7 450G sits within a tight cluster of high-performing desktop chips, trading blows within less than one percent of each other. The Intel Core 7 251E, with no such measurements, cannot be placed in this competitive landscape.

Architecture Differences

The two processors diverge fundamentally in their underlying design philosophy. The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c core architectures. It is fabricated on a 4 nm process at TSMC, with a die size of 195 mm². The Intel Core 7 251E uses the Bartlett Lake codename and belongs to the Core 7 generation, built on a 10 nm process at Intel's own foundry, with a larger die size of 257 mm². This process node difference is substantial: AMD's smaller 4 nm node generally allows for tighter transistor density and potentially lower power leakage, while Intel's 10 nm node is a larger geometry.

Core counts differ sharply. The AMD part uses 8 cores with 16 threads, while the Intel part uses 24 cores with 32 threads. That gives Intel a 3x advantage in raw core count and a 2x advantage in thread count. However, the cache hierarchy tells a more nuanced story. Both processors allocate 80 KB of L1 cache per core, but the AMD chip uses 1 MB of L2 per core, while the Intel chip uses 2 MB of L2 per core. The L3 cache is dramatically different: AMD offers 8 MB of total L3, while Intel offers 36 MB of shared L3. This means Intel has 4.5 times the L3 capacity, which can significantly benefit workloads that repeatedly access a working set larger than 8 MB.

Clock speeds also favor Intel on paper. The AMD chip has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel chip has a base clock of 2.10 GHz and a boost clock of 5.60 GHz. The Intel part boosts 500 MHz higher, which can translate to faster single-threaded execution in bursty workloads. Memory support differs as well: AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both use dual-channel memory buses with identical peak bandwidth of 89.6 GB/s. Both support ECC memory, making them viable for error-sensitive computing. PCIe connectivity differs, with AMD providing Gen 4 with 12 CPU lanes and Intel providing Gen 5 with 16 CPU lanes, giving Intel both a newer PCIe standard and more lanes for expansion devices.

Integrated graphics also differ. The AMD Ryzen AI 7 450G uses the Radeon 860M, while the Intel Core 7 251E uses UHD Graphics 770. The AMD processor has an unlocked multiplier, meaning users can adjust clock speeds for overclocking, while the Intel processor has a locked multiplier. The AMD processor uses AMD Socket AM5, while the Intel processor uses Intel Socket 1700. The AMD chip's part number is 100-000001917, and the Intel chip's part number is SRQDUQ657.

Where Each One Wins

Based on the available data, the AMD Ryzen AI 7 450G wins in every measured category simply because it has measurements. Its 93rd percentile ranking among all CPUs indicates that it outperforms the vast majority of processors in the database. The Intel Core 7 251E, with its 50th percentile ranking and zero average score, cannot claim any benchmark victory. However, architectural analysis from the specification sheet suggests where the Intel part might excel if data existed. The 24-core, 32-thread configuration with 36 MB of shared L3 cache is designed for heavily threaded workloads such as video rendering, scientific simulations, and database processing, where many parallel tasks can saturate all available cores. The higher 5.60 GHz boost clock could give Intel an edge in lightly threaded applications that depend on single-core speed.

The AMD chip, with 8 cores and 16 threads, relies on its Zen 5 architecture and 4 nm process for efficiency. Its higher percentile ranking (93 versus 50) suggests that the database's broader CPU population places it far above average. The Intel chip's 50th percentile, even without benchmark scores, implies it is positioned at the median, which is a weaker standing than the AMD chip's near-top-tier placement. For workloads that fit within the AMD chip's 8 MB L3 cache, such as typical office productivity, web browsing, and light content creation, the single-thread score of 4,309 and integer math score of 99,732 indicate strong responsiveness. For workloads that exceed that cache capacity or demand massive parallel throughput, the Intel chip's larger cache and core count would theoretically provide an advantage, but no recorded data confirms this.

The Verdict

The data presents a clear but incomplete picture. The AMD Ryzen AI 7 450G is a fully measured processor with an average benchmark score of 63,331 and a 93rd percentile standing, placing it among the top performers in the database. Its nearest rivals, including the Intel Core Ultra 7 265HX and the AMD Ryzen AI Max PRO 390, all sit within a 0.7 percent delta, confirming that the AMD chip competes at the high end of desktop performance. The Intel Core 7 251E has no recorded benchmark scores, a zero average, and a 50th percentile ranking, which means it cannot be compared on measured performance at all.

For users choosing strictly from the recorded data, the AMD Ryzen AI 7 450G is the only option with validated performance. It delivers strong single-thread results (4,309), high integer math throughput (99,732), and a multithread score of 30,422 that suits mainstream productivity and content creation. Its 4 nm process, unlocked multiplier, and AM5 socket make it a modern, overclockable platform. The Intel Core 7 251E, with its 24 cores, 32 threads, 36 MB L3 cache, and PCIe Gen 5 support, offers a compelling specification sheet for heavily parallel workloads, but the absence of any benchmark data means those specifications remain theoretical. The database cannot confirm that the Intel chip delivers on its architectural promise. The verdict, therefore, favors the AMD processor by default of evidence: it is the only chip in this comparison with measurable results, and those results place it in the 93rd percentile of all CPUs. The Intel chip's 50th percentile ranking, even without scores, positions it as an average performer, which the AMD chip clearly exceeds in recorded data.
