Architecture Differences

The AMD Ryzen 5 1500X is built on the Zen architecture, codenamed Summit Ridge, using a 14 nm process from GlobalFoundries. Its die size is 213 mm² with 4,800 million transistors. The Intel Core i5-1145GRE uses the Tiger Lake-U architecture with Willow Cove cores, fabricated on Intel’s 10 nm process, and has a smaller die at 144 mm².

Cache layouts differ substantially. The AMD chip has 96 KB of L1 cache per core and 512 KB of L2 per core, with a shared 16 MB L3 cache. The Intel part has 80 KB of L1 per core, a larger 1.25 MB of L2 per core, but only 8 MB of shared L3. This means the AMD chip offers double the L3 capacity, while Intel packs more L2 per core.

Memory support also diverges. The Ryzen 5 1500X supports DDR4 only, with a listed memory bandwidth of 42.7 GB/s. The Core i5-1145GRE supports both DDR4 and LPDDR4X, but no memory bandwidth figure is recorded in the database. Both parts support ECC memory and dual-channel configurations.

PCIe capabilities differ by generation and lane count. The AMD processor provides PCIe Gen 3 with 16 CPU lanes, while the Intel processor offers PCIe Gen 4 with only 4 CPU lanes. This reflects their intended platforms: the AMD chip is a desktop part on Socket AM4, while the Intel chip is a mobile part on BGA 1449.

The Ryzen 5 1500X has an unlocked multiplier, allowing overclocking, whereas the Intel Core i5-1145GRE is locked. The AMD chip carries a 65 W TDP, while the Intel part is rated at 28 W, indicating a much lower power envelope for mobile use. The Intel processor also includes integrated Iris Xe Graphics, which the AMD chip lacks entirely.

Head-to-Head Benchmarks

The benchmark data splits evenly, with each processor winning two tests. The AMD Ryzen 5 1500X takes both Cinebench R15 tests decisively. In multi-core R15, it scores 805 against 705, a 14.2% advantage. In single-core R15, the gap widens dramatically: 154 versus 99, a 55.6% lead. This older test suite clearly favors the Zen architecture’s raw per-thread throughput in this comparison.

The Intel Core i5-1145GRE reverses the trend in Cinebench R23. In multi-core, it posts 7001 versus 4597, a 34.3% margin that represents its best result. In single-core R23, it wins by a narrower 4.1%, scoring 988 against 947. The shift from R15 to R23 suggests the Intel chip benefits from newer instruction optimizations and a higher boost clock.

Looking at the broader benchmark picture, the Intel processor’s average score of 2025 edges out the AMD part’s 1992, a difference of roughly 1.7%. The Intel chip’s nearest rival is the Core i5-1130G7 at 2026, with a delta of -0.1%, while the AMD chip’s closest competitor is the Core i7-7920HQ at exactly 1992, showing a 0% delta. Both processors sit in the mid-40s percentile range, with Intel at 45 and AMD at 44.

The single-core R15 result is the outlier in this matchup. A 55.6% win for the AMD chip is far larger than any other margin recorded. This may reflect the Ryzen 5 1500X’s higher base clock of 3.50 GHz versus the Intel part’s oddly listed base clock of 1500.00 MHz, though the Intel chip boosts to 4.10 GHz. In contrast, the R23 single-core test shows only a 4.1% difference, suggesting the two architectures are closer in modern single-threaded workloads.

The Verdict

The data points to a generational and architectural split. The AMD Ryzen 5 1500X, released in April 2017, excels in older Cinebench R15 workloads, particularly single-core, where it beats the Intel chip by over half. Its 16 MB L3 cache and 42.7 GB/s memory bandwidth support its desktop-oriented design. For users running legacy benchmarks or older software, the Ryzen 5 1500X delivers demonstrably higher scores.

The Intel Core i5-1145GRE, released in September 2020, is the stronger choice for modern Cinebench R23 workloads. It leads multi-core by 34.3% and single-core by 4.1%, while also offering integrated graphics and a 28 W TDP for mobile efficiency. Its 10 nm process and Willow Cove architecture provide a clear advantage in newer, more demanding workloads.

Neither processor dominates outright, as the head-to-head record is tied at two wins each. The AMD chip’s wins are larger in margin, with a 55.6% single-core R15 blowout, but the Intel chip’s multi-core R23 lead of 34.3% is substantial in absolute score terms. The Intel part also holds a higher average benchmark score overall, 2025 versus 1992.

For desktop builders prioritizing older application performance and overclocking flexibility, the Ryzen 5 1500X is the data-backed pick. Its unlocked multiplier, 65 W TDP, and 16 PCIe Gen 3 lanes suit a traditional AM4 desktop setup. For mobile or embedded users needing lower power, integrated graphics, and modern workload performance, the Core i5-1145GRE is the clear winner.

Where Each One Wins

The AMD Ryzen 5 1500X wins in legacy benchmark scenarios. Its Cinebench R15 single-core score of 154 is 55.6% higher than the Intel chip’s 99, and its R15 multi-core score of 805 beats 705 by 14.2%. The larger 16 MB L3 cache, higher base clock of 3.50 GHz, and dual-channel DDR4 with 42.7 GB/s bandwidth support this profile. The unlocked multiplier and 65 W TDP also make it a better fit for overclocking on a desktop AM4 platform.

The Intel Core i5-1145GRE wins in modern compute-heavy tasks. Its Cinebench R23 multi-core score of 7001 is 34.3% ahead of the AMD chip’s 4597, and its single-core R23 score of 988 edges out 947 by 4.1%. The 10 nm process, Iris Xe Graphics, and 28 W TDP make it suitable for thin-and-light mobile systems. Its PCIe Gen 4 support, though limited to 4 lanes, provides newer connectivity options.

For raw average performance, the Intel part wins with 2025 versus 1992. For legacy software compatibility, the AMD part wins decisively. The choice depends on workload recency and platform constraints, not on overall superiority. The data shows a tie in win count, but a divergence in where those wins occur: AMD dominates old benchmarks, Intel dominates new ones.
