Architecture Differences

The two processors come from different Intel generations and process nodes. The Xeon E-2388G is based on Rocket Lake, built on a 14 nm process, and uses the Intel Socket 1200. The Celeron G6900 is based on Alder Lake, built on a 10 nm process, and uses the Intel Socket 1700. The Xeon is part of the Xeon E-2300 series, while the Celeron is a standalone desktop part.

Core and thread counts differ sharply. The Xeon has 8 cores and 16 threads, while the Celeron has 2 cores and 2 threads. This gives the Xeon a large advantage in parallel workloads. The Xeon also has a higher boost clock: 5.10 GHz versus no boost on the Celeron, which runs at a fixed 3.40 GHz base.

Cache hierarchies also differ. Both have 80 KB of L1 per core. The Xeon has 512 KB of L2 per core, while the Celeron has 1.25 MB per core. The Xeon's shared L3 is 16 MB, compared to 4 MB on the Celeron. The larger L3 on the Xeon helps with data reuse across eight cores.

Memory support is another major split. The Xeon supports DDR4 only, with a dual-channel bus and a memory bandwidth of 51.2 GB/s. The Celeron supports both DDR4 and DDR5, also dual-channel, but the database does not list a memory bandwidth figure. The Xeon supports ECC memory, while the Celeron does not. This makes the Xeon suitable for error-correcting workloads.

PCIe and integrated graphics differ as well. The Xeon has PCIe Gen 4 with 20 lanes (CPU only) and UHD Graphics P750. The Celeron has PCIe Gen 5 and UHD Graphics 710. The Xeon is classified as a server/workstation part, while the Celeron is a desktop part. Both are currently active in production, and both have locked multipliers.

Head-to-Head Benchmarks

The database includes six Cinebench tests, and the Xeon E-2388G wins all of them. The margins are consistent, with delta percentages around 424%. In Cinebench R15 multicore, the Xeon scores 2009 against the Celeron's 383, a delta of 424.5%. In R15 singlecore, the Xeon scores 283 versus 54, a delta of 424.1%. The R20 multicore test shows 8374 against 1599, a delta of 423.7%. R20 singlecore has 1181 versus 225, a delta of 424.9%. R23 multicore gives 19939 versus 3808, a delta of 423.6%. R23 singlecore gives 2814 versus 537, a delta of 424%.

The delta percentages are consistent across all six tests, indicating that the performance gap is not limited to one type of workload. Both multicore and singlecore tests show the same relative advantage. The Xeon's higher core count, boost clock, and larger cache all contribute to this result.

The Celeron does not win any of the six head-to-head tests. Its best relative performance is in R20 singlecore, where it still trails by 424.9%. The database records 6 wins for the Xeon and 0 for the Celeron.

Where Each One Wins

Based on the head-to-head benchmark data, the Xeon E-2388G wins every recorded test. It leads in both multicore and singlecore Cinebench workloads. The Xeon's 8 cores and 16 threads give it a decisive advantage in multithreaded tasks, while its 5.10 GHz boost clock and larger L3 cache help in single-threaded performance. The Celeron G6900 does not win any of the six head-to-head tests.

The Celeron does have advantages outside of benchmark scores. Its TDP of 46 W is lower than the Xeon's 95 W, which makes it more power-efficient for basic desktop use. It also supports DDR5 memory and PCIe Gen 5, while the Xeon is limited to DDR4 and PCIe Gen 4. However, these features do not translate into wins in the recorded Cinebench tests. The Celeron's 2 cores and 2 threads limit its performance ceiling, and its lack of a boost clock means it cannot match the Xeon's peak speed.

In practical terms, the Xeon is the clear choice for workloads that depend on CPU throughput, such as rendering, compilation, or server-side processing. The Celeron is suited for low-power systems where the newer memory and PCIe standards matter more than raw compute performance.

The Verdict

The data is unambiguous. The Intel Xeon E-2388G outperforms the Intel Celeron G6900 in every head-to-head benchmark recorded in the database. The Xeon's 8 cores, 16 threads, 5.10 GHz boost clock, and 16 MB L3 cache produce scores that are roughly 424% higher across all six Cinebench tests. The Celeron, with 2 cores, 2 threads, no boost clock, and 4 MB L3, cannot compete in these measurements.

The choice between the two depends on the use case. For server or workstation workloads that require maximum CPU performance, the Xeon E-2388G is the appropriate pick. Its ECC memory support and 51.2 GB/s memory bandwidth further reinforce its server orientation. For a low-power desktop system where DDR5 and PCIe Gen 5 are priorities, the Celeron G6900 offers a much lower TDP and a newer platform, but it sacrifices all measured performance. The database shows 6 wins for the Xeon and 0 for the Celeron, so any performance-sensitive application should favor the Xeon.
