AMD Ryzen 3 5125C vs Intel Xeon E3-1285 v4 Comparison

The Intel Xeon E3-1285 v4 and AMD Ryzen 3 5125C represent two very different design philosophies from two different eras of computing. The Xeon is a 2015 server/workstation part built on Intel’s 14 nm Broadwell architecture, while the Ryzen 3 is a 2022 mobile processor using TSMC’s 7 nm process with Zen 3 cores. Despite their contrasting origins, both land at the 43rd percentile among all CPUs in the database, with average benchmark scores of 1908 and 1902 respectively. This near-identical overall standing makes the comparison particularly interesting, as the data suggests they achieve parity through entirely different means.

Where Each One Wins

The benchmark data reveals a clear split in strengths between these two processors. The Intel Xeon E3-1285 v4 dominates in multi-threaded workloads, as evidenced by its Cinebench scores. In Cinebench R15 multicore, the Xeon scores 664 points, while the Ryzen 3 5125C has no comparable result in that test. Similarly, in Cinebench R20 multicore, the Xeon produces 2770 points, and in Cinebench R23 multicore it reaches 6596 points. These results stem from the Xeon’s 4 cores and 8 threads, which allow it to handle parallel tasks more effectively than the Ryzen 3’s 2 cores and 4 threads.

The AMD Ryzen 3 5125C, however, shows its strength in a different metric. Its Geekbench scores are notably strong: 2566 points in multicore and 1237 points in singlecore. These are the only benchmarks recorded for the Ryzen 3, but they paint a picture of a processor that excels in bursty, latency-sensitive tasks. The singlecore score of 1237 is particularly telling, as it suggests the Zen 3 architecture’s high instructions-per-clock (IPC) can keep up with or exceed the older Broadwell design in lightly-threaded scenarios.

The Xeon also holds advantages in cache configuration. Its L3 cache is 6 MB shared, while the Ryzen 3 offers 8 MB shared, but the Xeon counters with a smaller L2 cache of 256 KB per core against the Ryzen’s 512 KB per core. The Xeon’s memory bandwidth is listed at 29.9 GB/s, whereas the Ryzen 3 reaches 51.2 GB/s, indicating the AMD part is better suited for memory-intensive workloads if the software can utilize its dual-channel DDR4 interface effectively.

The Verdict

For users prioritizing multi-threaded productivity, the Intel Xeon E3-1285 v4 is the clear choice from this data. Its Cinebench R23 multicore score of 6596 vastly outpaces what the Ryzen 3 can achieve based on its 2-core design. The Xeon’s 4 cores and 8 threads provide a tangible advantage in rendering, compilation, or any workload that scales with thread count.

Conversely, the AMD Ryzen 3 5125C is better suited for mobile or power-constrained environments. Its 15 W TDP compared to the Xeon’s 95 W TDP means it generates far less heat and consumes less power, making it ideal for thin-and-light laptops. The Geekbench singlecore score of 1237 suggests responsive day-to-day performance for web browsing, office applications, and light creative work.

The data also shows that the Ryzen 3 supports DDR4 memory, while the Xeon is limited to DDR3. This gives the AMD part access to newer, faster memory technology, aligning with its higher theoretical memory bandwidth of 51.2 GB/s. For anyone building a new system today, the Ryzen 3’s active production status and modern platform make it the more sensible long-term investment, despite its lower core count.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are unavailable in the data, as the headToHeadBenchmarks field is empty. However, the individual benchmark suites provide enough information to infer relative performance.

The most significant win for the Intel Xeon E3-1285 v4 comes in Cinebench R23 multicore, where it scores 6596 points. This result reflects the Xeon’s ability to leverage 8 threads across its 4 cores. The Ryzen 3 5125C, with only 4 threads, would face a substantial deficit in this test, likely less than half the Xeon’s score given the core count difference.

In single-threaded performance, the picture is less one-sided. The Xeon scores 931 points in Cinebench R23 singlecore and 391 in R20 singlecore. The Ryzen 3’s Geekbench singlecore of 1237 is from a different benchmark, so direct comparison is not possible. However, the fact that the Ryzen 3 achieves a percentile rank of 43 with only 2 cores suggests its per-core performance is exceptionally strong, likely matching or exceeding the Xeon’s older Broadwell cores.

Looking at average benchmark scores, the two are nearly tied: the Xeon at 1908 and the Ryzen 3 at 1902. This difference of 6 points is negligible. The nearest rivals list for the Xeon includes the AMD Ryzen 5 PRO 2400GE at 1910 points (delta -0.1%), while the Ryzen 3’s rivals include the Intel Core i3-9100F at 1903 points (delta -0.1%). Notably, the Xeon E3-1285 v4 appears as a rival to the Ryzen 3 with a delta of -0.3%, confirming their near-identical overall standing.

Architecture Differences

The architectural divide between these two processors is stark. The Intel Xeon E3-1285 v4 uses the Broadwell architecture with the codename Broadwell-DT, built on a 14 nm process at Intel’s foundry. Its die size is 182 mm². The AMD Ryzen 3 5125C uses Zen 3 architecture with the codename Cezanne-U, fabricated on a 7 nm process at TSMC. Its die size is 180 mm², remarkably close to the Xeon’s, but the transistor count is vastly different at 10,700 million for the Ryzen 3, while the Xeon’s transistor count is not listed.

The Xeon’s cache hierarchy includes 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. The Ryzen 3 offers 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. This gives the Ryzen 3 a larger total cache capacity, which benefits repeated data access patterns.

Memory support differs fundamentally. The Xeon uses DDR3 with dual-channel configuration and a memory bandwidth of 29.9 GB/s. The Ryzen 3 uses DDR4 with dual-channel configuration and a memory bandwidth of 51.2 GB/s. This nearly doubles the theoretical bandwidth for the AMD part.

The integrated graphics also differ. The Xeon includes Intel Iris Pro P6300, while the Ryzen 3 features Radeon Vega 3. Both provide basic display output, but the Vega 3 is likely more modern and capable for media playback.

Specification Differences

The two processors differ in nearly every major specification field. The Intel Xeon E3-1285 v4 has a base clock of 3.50 GHz and a boost clock of 3.80 GHz. The AMD Ryzen 3 5125C has a base clock of 3.00 GHz with no listed boost clock. This gives the Xeon a raw clock speed advantage.

The socket types are incompatible: the Xeon uses Intel Socket 1150, while the Ryzen 3 uses AMD Socket FP6. This means they cannot be swapped into the same motherboard.

Power consumption differs dramatically, with the Xeon rated at 95 W TDP versus the Ryzen 3’s 15 W TDP. The PCIe configuration also varies, with the Xeon offering Gen 3 with 16 lanes (CPU only) and the Ryzen 3 offering Gen 3 with 8 lanes (CPU only).

The release dates are far apart, with the Xeon launching on 2015-06-01 and the Ryzen 3 on 2022-05-04. The Xeon had a launch MSRP of $556, while the Ryzen 3 has no listed launch MSRP. The Xeon is end-of-life, while the Ryzen 3 remains active. The Xeon’s part number is SR2CX, while the Ryzen 3’s is 100-000000xxx. Neither processor has an unlocked multiplier. The Xeon targets the server/workstation market, while the Ryzen 3 targets mobile devices.
