AMD Ryzen 7 5825C vs Intel Atom x7213RE Comparison

The Verdict

The recorded data presents an exceptionally clear hierarchy between these two mobile processors. The AMD Ryzen 7 5825C wins all five shared benchmark comparisons, with margins ranging from 451.5% to 455.3% in the Cinebench suite. The Intel Atom x7213RE, despite its lower power draw, never takes a single head-to-head benchmark. For any workload captured in the database, the AMD part is the unambiguous performance choice.

The AMD Ryzen 7 5825C delivers multi-core scores that are roughly 5.5 times higher than the Atom across every Cinebench iteration. In Cinebench R23 multi-core, the AMD scores 12376 against the Atom's 2244. Single-core results show the same pattern: 1747 versus 316 in R23 single-core. These are not marginal advantages; they represent fundamentally different performance tiers.

The Intel Atom x7213RE does hold one notable distinction. It has a 9 W TDP compared to the AMD's 15 W, making it the lower-power option. The database shows both parts occupy the same 55th percentile versus all CPUs, and their average benchmark scores are close (3579 for AMD versus 3520 for Intel), but that average is skewed by the Atom's additional PassMark results, which the AMD does not have recorded.

For users selecting between these two, the decision rests on workload priority. If the task requires sustained multi-threaded throughput, rendering, compilation, or any compute-heavy mobile workload, the Ryzen 7 5825C is the only rational choice based on the data. If the priority is minimal power consumption and the workload is light enough to tolerate single-channel memory and two cores, the Atom x7213RE presents a lower-power alternative, though it sacrifices the vast majority of compute capacity. The data does not support any scenario where the Atom wins a performance comparison.

Where Each One Wins

The AMD Ryzen 7 5825C wins every benchmark category that both processors share. These include Cinebench R15 multi-core, R20 multi-core and single-core, R23 multi-core and single-core. The margins are consistent, hovering around 451% to 455% across all five tests. This uniformity suggests the advantage is structural rather than workload-specific.

The Intel Atom x7213RE has no benchmark wins in the head-to-head dataset. Its strengths appear only in areas the database does not compare directly. The TDP of 9 W versus 15 W means the Atom draws less power, which can matter in thermally constrained or battery-powered designs. The Atom also supports DDR5 memory, while the AMD is limited to DDR4. However, the Atom's memory bus is single-channel with 38.4 GB/s bandwidth, while the AMD uses dual-channel with 51.2 GB/s.

The Atom does have additional PassMark benchmark results recorded, including data compression (27860), integer math (7058), floating-point math (4885), and single-thread performance (1601). These are not compared against the AMD because the AMD lacks corresponding entries. The presence of these scores contributes to the Atom's average benchmark score of 3520, which lands close to the AMD's 3579 average despite the AMD's overwhelming Cinebench victories.

The practical interpretation is straightforward. The Ryzen 7 5825C is for compute-bound tasks: video encoding, software compilation, 3D rendering, or any workload that scales with eight cores and sixteen threads. The Atom x7213RE is for embedded or low-power applications where the Cinebench scores are irrelevant and the 9 W envelope is the defining specification.

Architecture Differences

The AMD Ryzen 7 5825C is built on TSMC's 7 nm process with Zen 3 architecture, codenamed Cezanne-U. It belongs to the 5000 series and uses AMD Socket FP6. The silicon contains 10,700 million transistors on a 180 mm² die. Cache is distributed as 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3.

The Intel Atom x7213RE uses Amston Lake architecture with Gracemont cores, manufactured on Intel's 10 nm process. It uses Intel BGA 1264. The cache layout is different: 96 KB L1 per core, 2 MB shared L2, and 6 MB shared L3. The transistor count and die size are not recorded in the database.

The core configurations could hardly be more different. The AMD has 8 cores and 16 threads, allowing simultaneous multithreading. The Intel has 2 cores and 2 threads, with no hyper-threading. Base clocks are identical at 2.00 GHz, but the AMD boosts to 4.50 GHz while the Atom reaches 3.40 GHz.

Memory support diverges significantly. The AMD supports DDR4 only, through a dual-channel interface with 51.2 GB/s bandwidth. The Intel supports both DDR4 and DDR5, but through a single-channel interface capped at 38.4 GB/s. Neither processor supports ECC memory.

PCIe connectivity is similar in generation but different in lane count. The AMD provides Gen 3 with 8 CPU lanes; the Intel provides Gen 3 with 9 CPU lanes. Integrated graphics differ: the AMD uses Radeon Vega 8, while the Intel uses UHD Graphics 16EU.

The release dates are nearly two years apart. The AMD launched on May 4, 2022, and the Intel on April 7, 2024. Both are listed as Active in production and both have locked multipliers.

Head-to-Head Benchmarks

The head-to-head dataset contains five Cinebench comparisons, and the AMD Ryzen 7 5825C wins all five. The smallest margin is 451.5% in Cinebench R23 multi-core, where the AMD scores 12376 and the Atom scores 2244. The largest margin is 455.3% in Cinebench R20 single-core, with scores of 733 and 132 respectively.

Cinebench R15 multi-core shows the AMD at 1247 against the Atom's 226, a 451.8% advantage. Cinebench R20 multi-core follows the same pattern: 5197 versus 942, a 451.7% difference. Cinebench R23 single-core rounds out the set with 1747 versus 316, a 452.8% margin.

The consistency of these deltas is striking. Every test falls within a narrow band of 451.5% to 455.3%. This suggests the performance gap is not workload-dependent but reflects the fundamental difference in core count, thread count, and boost clock. The AMD's 4.50 GHz boost clock versus the Atom's 3.40 GHz, combined with 8 cores versus 2, creates a multiplicative advantage that appears uniformly across rendering workloads.

The AMD's average benchmark score of 3579 places it near the Intel Core i9-9980HK (3577, only 0.1% ahead) and ahead of the AMD Ryzen 7 2700E (3603, with the 5825C trailing by 0.7%). The Atom's average score of 3520 places it near the Intel Core i3-12300T (3525, 0.1% behind) and the AMD Ryzen 7 3800XT (3515, 0.2% ahead). These nearest-rival positions show both processors occupy similar percentile territory in the overall database, despite their massive head-to-head gap.

The PassMark results for the Atom are not part of the head-to-head comparison, but they provide context. The Atom scores 27860 in data compression, 1871 in data encryption, 4885 in floating-point math, and 7058 in integer math. Its single-thread PassMark score is 1601. These numbers are not compared against the AMD, so they cannot be used to close the gap, but they document the Atom's capabilities in lightweight embedded workloads.

Specification Differences

The two processors differ in nearly every measurable specification. The AMD Ryzen 7 5825C has 8 cores and 16 threads; the Intel Atom x7213RE has 2 cores and 2 threads. Base clocks match at 2.00 GHz, but boost clocks diverge: 4.50 GHz for AMD versus 3.40 GHz for Intel.

TDP is a major differentiator. The AMD draws 15 W, the Intel draws 9 W. Sockets are incompatible: AMD Socket FP6 for the Ryzen, Intel BGA 1264 for the Atom. The AMD uses Zen 3 architecture on a 7 nm TSMC process with 10,700 million transistors on a 180 mm² die. The Intel uses Amston Lake architecture with Gracemont cores on a 10 nm Intel process; its transistor count and die size are not recorded.

Cache layouts differ substantially. The AMD provides 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. The Intel provides 96 KB L1 per core, 2 MB shared L2, and 6 MB shared L3. Memory support favors the Intel in format (DDR4 and DDR5) but the AMD in bandwidth (51.2 GB/s dual-channel versus 38.4 GB/s single-channel). Neither supports ECC.

PCIe lanes are close: 8 for the AMD versus 9 for the Intel, both Gen 3. Integrated graphics differ: Radeon Vega 8 on the AMD, UHD Graphics 16EU on the Intel. The AMD's launch date is May 4, 2022; the Intel's is April 7, 2024. The Intel has a recorded launch MSRP of $42, while the AMD has no launch MSRP in the database. Both are Active in production, both are mobile-segment parts, and both have locked multipliers.
