AMD Ryzen 5 7500X3D vs Intel Core Ultra 5 250KF Plus Comparison

The AMD Ryzen 5 7500X3D and Intel Core Ultra 5 250KF Plus represent two fundamentally different approaches to desktop processing. The AMD part is a 6-core, 12-thread chip built on the 7000 series Raphael architecture, while the Intel part is an 18-core, 18-thread processor from the Core Ultra Series 2, based on the Arrow Lake Refresh design. The recorded benchmark data shows a clear and consistent performance gap, with the Intel processor winning all 11 head-to-head comparisons. However, the nature of those wins, the architectural choices, and the platform characteristics reveal distinct use-case profiles that go beyond a simple aggregate score.

Where Each One Wins

The Intel Core Ultra 5 250KF Plus dominates every measured workload in the database. This is not a narrow victory; it is a comprehensive sweep across all 11 benchmark tests. The most significant advantage appears in floating-point math, where the Intel chip scores 159824 against the AMD chip's 43594, a delta of -72.7% relative to the Intel score. This indicates a massive lead in workloads that rely heavily on parallel floating-point calculations, often found in scientific computing, financial modeling, and certain types of media encoding.

The Intel processor also shows overwhelming strength in data compression (553155 vs 271649, a -50.9% delta) and data encryption (41292 vs 15797, a -61.7% delta). These results suggest that the Intel chip, with its higher core count and thread count, is better suited for throughput-oriented tasks that can scale with many processing units. The multithread score of 50146 is exactly double the AMD's 25047, reinforcing the idea that the Intel chip can process roughly twice the amount of parallel work in a given time frame.

The AMD Ryzen 5 7500X3D does not win a single benchmark. Its strengths, therefore, are not visible in the raw performance numbers. Instead, its value proposition lies in its platform characteristics. It uses the AMD Socket AM5, which is a distinct ecosystem from Intel's Socket 1851. The AMD chip also features a 96 MB shared L3 cache, which is significantly larger than the Intel's 30 MB shared L3 cache. This large cache is often associated with improved performance in cache-sensitive workloads, but the recorded data here does not show a scenario where that translates into a win. The AMD chip also includes integrated Radeon Graphics, while the Intel part has no integrated graphics (N/A), making the AMD a more self-contained solution for basic display output.

The Verdict

Based strictly on the benchmark scores, the choice is unambiguous for raw performance: the Intel Core Ultra 5 250KF Plus is the superior processor. It wins all 11 head-to-head tests and holds a 93rd percentile ranking versus all CPUs, compared to the AMD's 89th percentile. The Intel chip's average benchmark score is 66159, which is 48% higher than the AMD's 44573. For any user whose primary concern is maximum computational throughput, multi-threaded performance, or single-thread speed, the data supports the Intel processor without reservation.

The AMD Ryzen 5 7500X3D, with its lower TDP of 65 watts compared to the Intel's 125 watts, is the more power-efficient option on paper. This, combined with its integrated graphics and smaller physical footprint (71 mm² die size vs 243 mm²), suggests a design focused on efficiency and platform simplicity. However, the database does not include any power consumption or thermal measurements to validate the real-world impact of this TDP difference. For a user who requires integrated graphics, a specific AM5 motherboard, or a lower thermal design point, the AMD chip is the only choice between these two, as the Intel part lacks any integrated graphics solution.

The Intel chip is also the only one with an unlocked multiplier (multiplierUnlocked: true), offering overclocking potential that the AMD chip does not provide. The launch MSRP for the Intel is $184, while the AMD is $269, but this price difference cannot be used to assess value. The verdict, therefore, is that the Intel Core Ultra 5 250KF Plus is the performance winner across every measured category. The AMD Ryzen 5 7500X3D is the appropriate selection only when its specific platform features, such as the integrated GPU or the AM5 socket, are mandatory requirements.

Head-to-Head Benchmarks

The head-to-head data presents a series of decisive Intel victories. The single-thread benchmark shows the Intel chip scoring 4698 against the AMD's 3494, a delta of -25.6%. This is the smallest percentage gap between the two, yet it still represents a substantial lead for Intel in single-core performance. This suggests that Intel's architecture, despite having many more cores, does not sacrifice per-core speed.

The largest margin is in floating-point math, where the Intel score of 159824 is more than three and a half times the AMD's 43594. This -72.7% delta is the single most lopsided result in the entire comparison. It indicates a fundamental architectural advantage for the Intel chip in handling parallel arithmetic operations. Similarly, the extended instructions test shows the Intel at 42880 versus the AMD's 20455, a -52.3% delta, confirming Intel's dominance in SIMD and specialized instruction workloads.

In integer math, the Intel chip scores 123030 against the AMD's 70774, a -42.5% delta. While still a clear Intel win, this gap is smaller than in floating-point, suggesting the AMD architecture is relatively stronger at integer operations than it is at floating-point. The physics test shows the closest result overall, with Intel scoring 3183 and AMD scoring 2779, a -12.7% delta. This is the only test where the percentage difference is in the single digits or low teens, hinting that the AMD chip can keep up better in certain specific algorithmic patterns.

The encryption and compression tests show Intel leads by margins of -61.7% and -50.9%, respectively. These are memory and cache-intensive workloads, yet the Intel chip's larger number of cores and higher memory bandwidth of 115.2 GB/s (vs AMD's 83.2 GB/s) appear to dominate the AMD's larger L3 cache. The random string sorting test also goes to Intel by -50.9%, further solidifying the pattern of Intel winning all throughput-oriented tasks by wide margins.

Architecture Differences

The two processors are built on different architectural blueprints. The AMD Ryzen 5 7500X3D is part of the Raphael family, using the Zen 4 core architecture. It is a 5 nm TSMC part with 11,270 million transistors on a 71 mm² die. The Intel Core Ultra 5 250KF Plus is an Arrow Lake Refresh part, using the Arrow Lake architecture. It is a 3 nm TSMC part with 17,800 million transistors on a much larger 243 mm² die. This difference in process node and die size indicates a shift in design philosophy: AMD opts for a smaller, denser chip focused on efficiency, while Intel uses a larger die to accommodate a significantly higher core count.

The core configuration is a major architectural contrast. The AMD chip uses 6 cores and 12 threads, indicating simultaneous multithreading. The Intel chip uses 18 cores and 18 threads, which means it has no hyperthreading; each core handles one thread. Despite having the same number of threads as cores, the Intel chip's raw core count of 18 gives it a substantial parallel processing advantage. The cache hierarchy also differs. AMD provides 64 KB of L1 and 1 MB of L2 per core, plus a massive 96 MB shared L3. Intel provides 192 KB of L1 and 3 MB of L2 per core, but only 30 MB of shared L3. The Intel chip has more per-core cache but much less shared cache, which may affect how it handles shared data sets.

The memory interface is dual-channel DDR5 for both, but the Intel chip has a higher rated memory bandwidth of 115.2 GB/s compared to the AMD's 83.2 GB/s. This could contribute to the Intel's performance lead in memory-intensive tasks. The PCIe support also differs: the AMD chip provides Gen 5 with 24 lanes from the CPU, while the Intel chip provides Gen 5 with 20 lanes. This gives the AMD platform more potential for high-speed expansion devices. The Intel chip is the only one with an unlocked multiplier, indicating it is designed for overclocking, whereas the AMD chip does not offer this feature.

Specification Differences

The core and thread counts are the most obvious difference: 6 cores and 12 threads for the AMD, versus 18 cores and 18 threads for the Intel. Clock speeds also differ, with the AMD base clock at 4.00 GHz and boost at 4.50 GHz, while the Intel base clock is 4.20 GHz and boost is 5.30 GHz. The Intel chip has a higher clock speed in both states. The thermal design power (TDP) is 65 watts for the AMD and 125 watts for the Intel, a significant difference in rated power consumption.

The socket and platform are entirely different. The AMD uses AMD Socket AM5, while the Intel uses Intel Socket 1851. This means they are not interchangeable on the same motherboard. The process node, as mentioned, is 5 nm for AMD and 3 nm for Intel. The transistor count and die size are also different: 11,270 million and 71 mm² for AMD, versus 17,800 million and 243 mm² for Intel. The integrated graphics differ, with AMD offering Radeon Graphics and Intel offering none (N/A). The PCIe lane count differs (24 for AMD vs 20 for Intel), and the memory bandwidth is higher for Intel (115.2 GB/s vs 83.2 GB/s). The multiplier is locked on the AMD and unlocked on the Intel. The release dates are also different, with the AMD released on 2025-11-11 and the Intel on 2026-03-10. The launch MSRP is $269 for the AMD and $184 for the Intel, though this is not a factor for performance analysis.
