AMD Ryzen 3 PRO 4450U vs Intel Core i5-10500 Comparison

The Intel Core i5-10500 and AMD Ryzen 3 PRO 4450U are both active processors that land at the 48th percentile among all CPUs, but they approach performance from different directions. The Intel part, a 6-core/12-thread desktop chip from Comet Lake, wins six of the eight head-to-head benchmark comparisons, while the AMD part, a 4-core/8-thread mobile chip from Zen 2, takes the two Geekbench tests. The data shows a clear split: the i5-10500 leads in every Cinebench iteration, while the Ryzen 3 PRO leads in Geekbench, making the choice heavily dependent on which workload family matches the user's priorities.

The Verdict

The Intel Core i5-10500 is the pick for multi-threaded rendering and CPU-heavy desktop tasks. It holds a consistent 5.5–6% advantage over the Ryzen 3 PRO 4450U across all six Cinebench tests, with its largest lead in Cinebench R15 single-core at 6% (123 vs 116). Its 6 cores and 12 threads, combined with a 65W TDP and Intel Socket 1200, position it as a desktop workhorse that outpaces the mobile AMD chip in synthetic render workloads. The data shows a 5.5% win in Cinebench R23 multi-core (8686 vs 8230) and a 5.6% win in R20 multi-core (3648 vs 3456), reinforcing that the extra two cores translate directly into render performance.

The AMD Ryzen 3 PRO 4450U is the pick for Geekbench-style workloads and power-sensitive mobile systems. It wins Geekbench multi-core by 12% (3840 vs 3381) and Geekbench single-core by 5.4% (1181 vs 1117), despite having fewer cores and a lower 15W TDP. Its 7 nm process node and 9,800 million transistors on a 156 mm² die from TSMC deliver higher memory bandwidth at 68.3 GB/s versus the Intel's 42.7 GB/s, which likely explains the Geekbench advantage. For users comparing mobile platforms, the Ryzen 3 PRO offers a better balance of efficiency and memory throughput, but it cannot match the Intel part in Cinebench renders.

Benchmark results indicate a near-tie in average scores: the i5-10500 averages 2446, while the Ryzen 3 PRO averages 2413, a difference of only 1.4%. The nearest rivals for each chip confirm this parity — the i5-10500 sits between the Xeon D-1541 (2447, -0.1%) and the Core i5-8600 (2454, -0.3%), while the Ryzen 3 PRO sits between the Xeon E5-2630L v3 (2409, +0.2%) and the Core i7-9850HE (2421, -0.3%). If the workload is Cinebench, choose Intel; if Geekbench, choose AMD.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i5-10500 uses the Comet Lake architecture, built on a 14 nm process node at Intel's own foundry. It is a desktop part with a 65W TDP, featuring 6 cores and 12 threads. The AMD Ryzen 3 PRO 4450U uses the Zen 2 architecture with the Renoir codename, built on a 7 nm process node at TSMC. It is a mobile part with a 15W TDP, featuring 4 cores and 8 threads. The AMD chip packs 9,800 million transistors on a 156 mm² die, while the Intel chip's transistor count and die size are not specified in the data.

Cache configurations diverge significantly. Both share 64 KB of L1 cache per core, but the Intel part has 256 KB of L2 per core and 12 MB of shared L3 cache. The AMD part has 512 KB of L2 per core but only 4 MB of shared L3. This means the Intel chip has three times the L3 cache, which can benefit workloads with large working sets, while the AMD chip compensates with double the L2 per core and a more advanced process node.

Integrated graphics also differ: the Intel part includes UHD Graphics 630, while the AMD part includes Radeon Graphics with 320 SP. Neither chip supports ECC memory. PCIe support is Gen 3 for both, but the Intel part specifies 16 lanes from the CPU, while the AMD part lists only "Gen 3" without a lane count. The Intel chip uses Intel Socket 1200, while the AMD chip uses AMD Socket FP6, making them incompatible with the same motherboards.

Specification Differences

The two processors differ in several key specifications. The Intel Core i5-10500 has 6 cores and 12 threads, while the AMD Ryzen 3 PRO 4450U has 4 cores and 8 threads. Base clocks are 3.10 GHz for Intel versus 2.40 GHz for AMD, and boost clocks are 4.50 GHz versus 3.70 GHz. TDP is 65W for Intel versus 15W for AMD, reflecting the desktop versus mobile market segmentation.

Memory bandwidth favors AMD at 68.3 GB/s versus Intel's 42.7 GB/s, despite both using dual-channel DDR4. L2 cache is 256 KB per core on Intel versus 512 KB per core on AMD, while L3 cache is 12 MB shared on Intel versus 4 MB shared on AMD. The process node is 14 nm for Intel versus 7 nm for AMD, with the AMD chip fabricated by TSMC. Release dates are close: Intel on 2020-04-29 and AMD on 2020-05-06. Neither chip has an unlocked multiplier, and neither has a launch MSRP listed. Part numbers are SRH3A for Intel and 100-000000104 for AMD.

Head-to-Head Benchmarks

The benchmark data reveals a consistent pattern. The Intel Core i5-10500 wins all six Cinebench tests, with deltas ranging from 5.5% to 6%. The smallest margin is in Cinebench R15 multi-core (875 vs 829, a 5.5% lead) and the largest is in Cinebench R15 single-core (123 vs 116, a 6% lead). In Cinebench R20, Intel leads multi-core by 5.6% (3648 vs 3456) and single-core by 5.5% (514 vs 487). In Cinebench R23, Intel leads multi-core by 5.5% (8686 vs 8230) and single-core by 5.6% (1226 vs 1161).

The AMD Ryzen 3 PRO 4450U counters in Geekbench. Its multi-core lead is substantial at 12% (3840 vs 3381), which is the largest delta of any test in either direction. Its single-core lead is 5.4% (1181 vs 1117), slightly smaller than Intel's single-core wins in Cinebench. This split suggests that Geekbench's workload favors the AMD chip's higher memory bandwidth and Zen 2 architecture, while Cinebench favors Intel's higher clock speeds and additional cores.

The overall win count is 6 for Intel and 2 for AMD. The average benchmark scores are close — 2446 for Intel and 2413 for AMD — but the per-test deltas show that the choice depends entirely on which benchmark suite is more representative of the user's actual workload.

Where Each One Wins

The Intel Core i5-10500 wins in every Cinebench test, making it the choice for render-based workloads that scale with core count and clock speed. Its 6 cores and 12 threads, combined with a 4.50 GHz boost clock and 12 MB of L3 cache, deliver a 5.5-6% edge in both single-core and multi-core render tests. The 65W TDP and desktop socket (Intel Socket 1200) indicate it is designed for sustained performance in a desktop chassis, where power draw is less constrained than in a laptop.

The AMD Ryzen 3 PRO 4450U wins in Geekbench, both single-core and multi-core. Its 68.3 GB/s memory bandwidth is 60% higher than Intel's 42.7 GB/s, which likely drives the 12% multi-core Geekbench advantage. The 15W TDP and mobile socket (AMD Socket FP6) position it for thin-and-light laptops, where efficiency and memory throughput matter more than raw render performance. Its 7 nm process node from TSMC also suggests better power efficiency per transistor, though the data does not include wattage measurements to confirm this.

The nearest rivals underscore the different competitive landscapes. The Intel chip competes with server-class Xeons (D-1541 at -0.1%) and older desktop i5s (i5-8600 at -0.3%). The AMD chip competes with Xeon E5-2630L v3 (+0.2%) and mobile i7s (i7-9850HE at -0.3%), as well as the Ryzen 5 4680U at -0.5%. For a desktop user running Cinebench, the i5-10500 is the stronger choice. For a mobile user running Geekbench, the Ryzen 3 PRO provides a clear advantage, especially in multi-core scenarios where its memory bandwidth and architecture shine.
