AMD Ryzen 3 PRO 5475U vs Intel Xeon E5-4627 v3 Comparison

Head-to-Head Benchmarks

The benchmark data presents an unusually close contest between the AMD Ryzen 3 PRO 5475U and the Intel Xeon E5-4627 v3. Across six head-to-head Cinebench tests, the AMD part wins every single round, but the margins are remarkably slim. The largest advantage for the Ryzen 3 PRO 5475U appears in the Cinebench R20 single-core test, where it scores 573 against the Xeon's 571, a lead of 0.4%. Every other test shows a delta of 0.3% or less.

In Cinebench R15 multicore, the AMD Ryzen 3 PRO 5475U scores 974, while the Intel Xeon E5-4627 v3 scores 971, a difference of just 0.3%. The single-core result in that same test is exactly tied at 137 points each, although the database records the AMD chip as the winner due to the rounding in the delta calculation. The Cinebench R20 multicore test shows 4062 for the Ryzen against 4049 for the Xeon, again a 0.3% gap. In Cinebench R23, the multicore scores are 9673 and 9642, respectively, while the single-core scores are 1365 and 1361.

The overall win tally is 6 to 0 in favor of the AMD Ryzen 3 PRO 5475U. However, the average benchmark score tells a broader story. The Ryzen's average is 2865, while the Xeon's average is 2789. That is a 2.7% difference in the aggregate, which is larger than any single head-to-head test, suggesting that the Ryzen's advantage is consistent but not dramatic. The percentile ranking for both CPUs is identical at 51 out of all recorded CPUs, which places them in the same performance tier despite the differing architectures and market segments.

Where Each One Wins

The data splits cleanly by workload type, even if the margins are razor thin. The AMD Ryzen 3 PRO 5475U takes all six Cinebench submissions, spanning both single-core and multi-core tests. This includes the R15, R20, and R23 versions. The largest single-core lead is 0.4% in R20, while the largest multicore lead is 0.3% in both R15 and R23. For pure rendering tasks, the Ryzen is the consistent, if marginal, winner.

The Intel Xeon E5-4627 v3 does not win a single benchmark in the head-to-head set. Yet its average score of 2789 places it within 0.1% of the Intel Core i5-11300H (2792) and 0.6% below the Intel Core i5-8600K (2807). The Ryzen 3 PRO 5475U, by comparison, has an average of 2865, which puts it 0.2% ahead of the Intel Core i7-11370H (2861) and 1.0% ahead of the Intel Core i7-6800K (2838). The Xeon's nearest rival is the AMD Ryzen 3 PRO 4350G (2774), which it barely edges by 0.5%.

The practical interpretation is that the Ryzen is better suited for latency-sensitive and lightly threaded tasks, given its single-core wins, while the Xeon, despite losing the multicore tests, still posts very close numbers in those same tests. In the database, the Xeon's score is close enough that its 10 cores and 20 threads almost overcome the Ryzen's newer architecture. For users who rely on Cinebench as a proxy for general CPU throughput, the choice is nearly a coin flip, but the AMD holds a narrow edge in every recorded metric.

Architecture Differences

The architectural gap is substantial. The AMD Ryzen 3 PRO 5475U is built on TSMC's 7 nm process, featuring 10,700 million transistors on a 180 mm² die. It uses the Zen 3 architecture, codenamed Cezanne-U, with 4 cores and 8 threads. The Xeon E5-4627 v3, in contrast, is a 22 nm Intel part, Haswell-EP, with 2,600 million transistors on a 356 mm² die, and it packs 10 cores with 20 threads. The transistor density difference is stark: the AMD chip has four times the transistor count in half the die area.

Cache layouts also differ. The Ryzen has 64 KB of L1 per core and 512 KB of L2 per core, with 8 MB of shared L3. The Xeon has the same 64 KB per core L1, but only 256 KB of L2 per core, and a much larger 25 MB of shared L3. The Xeon's larger L3 is typical for a server part, but the per-core L2 advantage goes to the AMD. The Ryzen's L3 is shared across only 4 cores, while the Xeon's is shared across 10 cores.

Memory support diverges significantly. The Ryzen supports DDR4 with a dual-channel bus, delivering 51.2 GB/s of bandwidth. The Xeon also supports DDR4, but with a quad-channel bus, delivering 68.3 GB/s. The Xeon also supports ECC memory, while the Ryzen does not. This makes the Xeon more suitable for error-correcting workloads, despite its older node. The PCIe situation is reversed: the Xeon provides Gen 3 with 40 lanes (CPU only), while the Ryzen provides Gen 3 with only 8 lanes. The Xeon's lane count is critical for server expansion, while the Ryzen is a mobile part.

Another key difference is integrated graphics. The Ryzen includes a Radeon Vega 6 iGPU, while the Xeon has none. The Ryzen's TDP is 15 W, versus the Xeon's 135 W. The AMD part is listed as Active, while the Xeon is End-of-life. The release dates are 2022-04-18 for the Ryzen and 2015-05-31 for the Xeon, a difference of roughly seven years. The Ryzen is a mobile part, while the Xeon is a server/workstation part.

The Verdict

The data points to a clear, if narrow, victory for the AMD Ryzen 3 PRO 5475U in raw Cinebench performance. It wins all six head-to-head tests, including the multi-core tests where the Xeon's 10 cores and 20 threads should theoretically give it an advantage. The AMD's 4 cores and 8 threads on Zen 3 architecture overcome the Xeon's core count advantage, likely due to higher IPC and a much newer process node. The Ryzen's boost clock of 4.10 GHz against the Xeon's 3.20 GHz helps in single-core tasks, but the multicore wins suggest the architecture is just more efficient per thread.

For a user building a server or workstation, the Xeon E5-4627 v3 offers ECC memory, quad-channel bandwidth (68.3 GB/s), and 40 PCIe lanes, which are absent on the Ryzen. Yet the Ryzen has a 15 W TDP versus 135 W, making it far more power-efficient. The Xeon is a server part with a launch MSRP of $2225, while the Ryzen has no MSRP listed, indicating a mobile-focused silicon. The Xeon is end-of-life, while the Ryzen is still active.

If the workload is purely CPU rendering, the AMD is the better pick, based on the recorded scores. If the workload needs ECC, high memory bandwidth, or extensive PCIe expansion, the Xeon is the only choice. For general mobile computing, the AMD wins due to the integrated Radeon GPU and lower power draw. The data does not show any scenario where the Xeon outperforms the AMD in Cinebench, so the verdict is a 6-0 win for the AMD in raw compute, with the Xeon's value resting entirely on its server-specific features.
