AMD Ryzen 3 PRO 5475U vs Intel Atom x7211RE Comparison

The AMD Ryzen 3 PRO 5475U and the Intel Atom x7211RE sit at opposite ends of the mobile processor spectrum. The Ryzen is a 4-core, 8-thread Zen 3 part built for mainstream laptops, while the Atom is a 2-core, 2-thread Gracemont design aimed at low-power embedded systems. The database's head-to-head results are decisive: the Ryzen wins all five shared benchmarks, with margins between 436.2% and 440.6%. The Atom counters with a 6W TDP, but the recorded measurements show a performance gap that no efficiency advantage can close.

Head-to-Head Benchmarks

The head-to-head comparison leaves no room for ambiguity. The AMD Ryzen 3 PRO 5475U wins all five recorded tests, and every margin exceeds 436%. In Cinebench R23 multicore, the Ryzen scores 9673 against the Atom's 1804, a 436.2% advantage. The R23 single-core test shows 1365 versus 254, a 437.4% lead. Cinebench R20 multicore records 4062 against 757, a 436.6% margin, while R20 single-core delivers 573 versus 106, the largest relative gap at 440.6%. The oldest test, Cinebench R15 multicore, shows 974 for the Ryzen and 181 for the Atom, a 438.1% difference.

These are not close contests. The smallest margin is 436.2%, meaning the Ryzen outperforms the Atom by at least 436.2% in every shared benchmark. The pattern holds across both multicore and single-core workloads, indicating that the AMD part's advantage comes from higher per-thread performance and better parallel scaling. The Ryzen's 4 cores and 8 threads, combined with a 4.10 GHz boost clock, overwhelm the Atom's 2 cores and 2 threads at 3.20 GHz.

The database places both processors at the 51st percentile among all CPUs, but that figure masks the gulf between them. The Ryzen's average benchmark score is 2865, while the Atom's is 2811. The Atom's average is supported by its Passmark results, which include tests not shared with the Ryzen. In the head-to-head Cinebench suite, the Atom is consistently outclassed. For additional context, the Ryzen's average score sits 0.2% above the Intel Core i7-11370H's 2861 and 0.8% above the Intel Xeon E-2126G's 2842. The Atom's average of 2811 is 0.2% above the Intel Core i5-8600K's 2807 and 0.7% above the Intel Core i5-11300H's 2792.

The Verdict

The data is unambiguous: the AMD Ryzen 3 PRO 5475U is the faster processor in every measured category. Anyone choosing between these two for compute-heavy work should select the Ryzen. It delivers 436.2% to 440.6% higher scores across the Cinebench suite, a margin that translates directly into faster rendering, compilation, and general productivity.

The Intel Atom x7211RE has its own strengths, but they are not computational. Its 6W TDP is lower than the Ryzen's 15W, making it suitable for fanless or battery-critical designs. However, the recorded data shows that the Atom's performance is dramatically lower, and its 2-core, 2-thread configuration limits it to light workloads.

The verdict depends on the use case. For a laptop or mini PC where performance matters, the Ryzen 3 PRO 5475U is the only rational choice. For an embedded controller, a thin client, or a device where power draw is the primary constraint, the Atom x7211RE's efficiency profile may justify its selection despite the performance deficit. The Ryzen's 5 wins and the Atom's 0 wins in the head-to-head comparison reflect the true balance of power.

Q: When were these processors released?

A: The Ryzen 3 PRO 5475U was released on 2022-04-18, and the Atom x7211RE was released on 2024-04-07.

Q: Do both processors have integrated graphics?

A: Yes. The Ryzen has Radeon Vega 6, and the Atom has UHD Graphics 16EU. The database does not include graphics benchmarks for either.

Specification Differences

The two processors differ in nearly every specification. The Ryzen 3 PRO 5475U has 4 cores and 8 threads, while the Atom x7211RE has 2 cores and 2 threads. Base clocks are 2.70 GHz for the Ryzen and 1.00 GHz for the Atom; boost clocks are 4.10 GHz and 3.20 GHz respectively. TDP is 15W for the Ryzen and 6W for the Atom.

The Ryzen uses AMD Socket FP6, while the Atom uses Intel BGA 1264. Memory support differs: the Ryzen supports DDR4 only, in dual-channel configuration with 51.2 GB/s bandwidth; the Atom supports DDR4 and DDR5, but in single-channel configuration with 38.4 GB/s bandwidth. PCIe lanes also differ: the Ryzen has Gen 3 with 8 lanes, while the Atom has Gen 3 with 9 lanes.

Integrated graphics are Radeon Vega 6 on the Ryzen and UHD Graphics 16EU on the Atom. Release dates are 2022-04-18 for the Ryzen and 2024-04-07 for the Atom. The Atom has a launch MSRP of $42; the Ryzen has no recorded launch MSRP. Neither processor has an unlocked multiplier.

Architecture Differences

The architectural gap is fundamental. The Ryzen 3 PRO 5475U uses AMD's Zen 3 architecture on the Cezanne-U codename, built on a 7 nm process at TSMC with 10,700 million transistors on a 180 mm² die. The Atom x7211RE uses Intel's Gracemont architecture on the Amston Lake codename, built on a 10 nm process at Intel. The Ryzen's transistor count and die size are recorded; the Atom's are not.

Cache layouts differ significantly. The Ryzen has 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. The Atom has 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The Ryzen's per-core L2 design suits its 4-core configuration, while the Atom's shared L2 reflects its simpler 2-core design.

The Ryzen is part of the 5000 series and the Ryzen 3 generation, while the Atom is part of the Atom generation. The Ryzen's foundry is TSMC; the Atom's is Intel. These architectural differences explain the performance gap: Zen 3 is a high-performance desktop-derived core, while Gracemont is an efficiency-focused Atom core.

Where Each One Wins

The AMD Ryzen 3 PRO 5475U wins every benchmark in the head-to-head comparison. Its strengths are in multi-threaded and single-threaded compute, as shown by Cinebench R15, R20, and R23 results. It is the clear choice for rendering, video encoding, software compilation, and any workload that benefits from 8 threads and a 4.10 GHz boost clock. The database also records Geekbench scores of 4525 multicore and 1612 single-core for the Ryzen, along with a Cinebench R15 single-core score of 137, though the Atom has no Geekbench results for comparison.

The Intel Atom x7211RE wins in efficiency. Its 6W TDP enables fanless designs and extended battery life. The Atom's Passmark results show some capability in specific tasks: data compression at 20820, integer math at 6517, floating-point math at 4303, and random string sorting at 2712. These scores indicate that the Atom can handle light data processing, but its 2-core, 2-thread design and 1.00 GHz base clock limit it to basic workloads.

The use-case split is stark. The Ryzen is for users who need real performance in a mobile form factor. The Atom is for developers building low-power embedded systems where the 6W TDP and small footprint matter more than compute throughput. The recorded data shows no scenario where the Atom outperforms the Ryzen in the shared Cinebench tests, so the decision comes down to power draw versus performance.
