AMD Ryzen 7 PRO 5875U vs Intel Xeon E-2278GE Comparison

The AMD Ryzen 7 PRO 5875U and Intel Xeon E-2278GE are both 8-core, 16-thread processors, but they target very different market segments: one is a low-power mobile part, the other a high-TDP server/workstation chip. The benchmark data shows a remarkably consistent story: the Ryzen 7 PRO 5875U wins every single head-to-head test, though by narrow margins that point to architectural efficiency rather than raw dominance.

Head-to-Head Benchmarks

The data shows a clean sweep for the AMD Ryzen 7 PRO 5875U, which claims victory in all six head-to-head comparisons. In Cinebench R15, the AMD chip scores 1421 in multi-core and 200 in single-core, beating the Intel Xeon E-2278GE's 1372 and 193 respectively. Both of those wins come with a deltaPct of 3.6%. Moving to Cinebench R20, the Ryzen 7 PRO 5875U posts 5922 multi-core and 835 single-core, while the Xeon E-2278GE trails at 5719 and 807. The deltaPct narrows slightly to 3.5% for both tests. Cinebench R23 continues the pattern: the AMD part scores 14102 multi-core and 1990 single-core, versus the Intel's 13619 and 1922, again with a 3.5% advantage in each discipline.

The consistency of these margins is notable. Across three generations of Cinebench workloads — R15, R20, and R23 — the performance gap between the two chips stays tightly clustered between 3.5% and 3.6%. This suggests a stable, workload-independent advantage rather than a spike in any particular test. The Ryzen 7 PRO 5875U's single-core lead is especially telling: it wins by 3.6% in R15 and 3.5% in R20 and R23, despite the Xeon E-2278GE having a higher boost clock of 4.70 GHz compared to the AMD's 4.50 GHz.

The average benchmark scores reinforce the head-to-head results. The Ryzen 7 PRO 5875U carries an avgBenchmarkScore of 3971, while the Xeon E-2278GE sits at 3939. That is a difference of roughly 0.8% overall, but the head-to-head deltas show the AMD chip's advantage is more pronounced in the Cinebench suite. Both processors land at the 57th percentile vs all CPUs, placing them in the same performance tier overall, yet the Ryzen still finds a way to edge ahead in every measured test.

The Verdict

From the data alone, the AMD Ryzen 7 PRO 5875U is the outright winner. It beats the Intel Xeon E-2278GE in every benchmark listed, with margins ranging from 3.5% to 3.6%. There is no category — multi-core, single-core, or any of the three Cinebench versions — where the Intel chip takes the lead. For raw compute performance as measured by these tests, the choice is unambiguous.

However, the selection is not purely about benchmark scores. The Xeon E-2278GE carries a launch MSRP of $519, while the Ryzen 7 PRO 5875U has no launch MSRP listed. The Intel part is also end-of-life in production status, whereas the AMD chip remains active. The Xeon E-2278GE uses an Intel Socket 1151 with PCIe Gen 3, 16 lanes, while the Ryzen 7 PRO 5875U uses AMD Socket FP6 with PCIe Gen 3, 8 lanes. The Intel chip also supports ECC memory, a feature absent from the AMD part. These are practical distinctions that may outweigh a 3.5% performance deficit for specific deployment scenarios.

For anyone building around an existing Socket 1151 platform or requiring ECC memory, the Xeon E-2278GE remains a viable choice despite losing every benchmark. For anyone prioritizing raw compute performance and energy efficiency in a mobile form factor, the Ryzen 7 PRO 5875U is the clear pick.

Where Each One Wins

The AMD Ryzen 7 PRO 5875U wins on pure performance. It is ahead in all six head-to-head tests, covering both multi-core and single-core scenarios across three Cinebench versions. The 3.5% to 3.6% margins are consistent, meaning the AMD chip is faster whether the workload is heavily threaded or latency-sensitive single-threaded. Its 15 W TDP, versus the Xeon E-2278GE's 80 W, also makes it the far more power-efficient option, though that is not a benchmark score.

The Intel Xeon E-2278GE wins on platform features and longevity considerations. It supports ECC memory, which is critical for error-sensitive server and workstation workloads. It has double the PCIe lanes (16 versus 8) for the CPU, allowing more expansion devices. It also uses the ubiquitous Socket 1151, which may be present in existing systems. The Xeon E-2278GE has a higher base clock (3.30 GHz versus 2.00 GHz) and boost clock (4.70 GHz versus 4.50 GHz), though this does not translate into a benchmark victory.

In terms of production status, the Xeon E-2278GE is end-of-life, while the Ryzen 7 PRO 5875U is active. This means the AMD chip is likely easier to source for new builds, while the Intel part may only be available via existing inventory or used markets. The AMD chip also has a smaller process node (7 nm versus 14 nm), which contributes to its lower TDP.

Architecture Differences

The two processors come from different architectural generations and manufacturing processes. The AMD Ryzen 7 PRO 5875U is based on Zen 3 architecture with the codename Cezanne-U, built on a 7 nm process at TSMC with 10,700 million transistors on a 180 mm² die. The Intel Xeon E-2278GE uses Coffee Lake architecture with the codename Coffee Lake-S WS, built on a 14 nm process at Intel, also on a 180 mm² die but with no transistor count listed.

Both chips feature 8 cores and 16 threads, and both have 16 MB of shared L3 cache. The L1 cache is identical at 64 KB per core. The L2 cache differs: the AMD chip has 512 KB per core, while the Intel chip has 256 KB per core. That gives the AMD part a larger total L2 footprint, which may contribute to its benchmark edge.

Memory support is similar in type — both use DDR4 with dual-channel buses — but the bandwidth differs. The AMD Ryzen 7 PRO 5875U reaches 51.2 GB/s, while the Intel Xeon E-2278GE is rated at 42.7 GB/s. The Intel chip supports ECC memory; the AMD chip does not. PCIe connectivity also diverges: the AMD part offers Gen 3 with 8 lanes, while the Intel part offers Gen 3 with 16 lanes.

Integrated graphics differ as well. The AMD Ryzen 7 PRO 5875U includes Radeon Vega 8, while the Intel Xeon E-2278GE includes UHD Graphics P630. The AMD chip is a mobile part (Socket FP6) with a 15 W TDP, while the Intel chip is a server/workstation part (Socket 1151) with an 80 W TDP. The AMD part was released on 2022-04-18 and is still in active production, while the Intel part was released on 2019-06-10 and is now end-of-life. Both processors have locked multipliers, meaning overclocking is not officially supported.
