Architecture Differences

The Intel Xeon E-2276G belongs to the Xeon E-2200 series, built on the Coffee Lake-S WS architecture with a 14 nm process from Intel's own foundry. It packs 6 cores and 12 threads, with a die size of 154 mm². Its cache hierarchy consists of 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3 cache. The integrated HD Graphics P630 is present. This is a server and workstation part, designed for Intel Socket 1151, and it is now end-of-life.

The AMD Ryzen 7 3800XT comes from the Ryzen 3000 series, using the Zen 2 architecture under the Matisse 2 codename. It is manufactured on TSMC's 7 nm process and contains 8 cores and 16 threads. The die size is 74 mm², with 3,800 million transistors. Its cache structure is different: 64 KB of L1 per core, 512 KB of L2 per core, and a larger 32 MB of L3 cache. There is no integrated graphics on this chip. It targets the desktop segment on AMD Socket AM4 and remains in active production.

The node advantage is significant. The 7 nm TSMC process allows AMD to fit more cores and a larger L3 pool into a much smaller die. The Xeon's 14 nm process is older, and the larger die reflects that. The memory bandwidth also differs, with AMD listing 51.2 GB/s versus Intel's 42.7 GB/s, though both use dual-channel DDR4. PCIe support is another split: the Xeon runs Gen 3 with 16 CPU lanes, while the Ryzen 7 3800XT supports Gen 4.

The market positioning is reflected in the silicon. Intel's Xeon includes ECC memory validation and integrated graphics, both workstation-friendly features. AMD's Ryzen 7 3800XT instead offers more cores, an unlocked multiplier, and a newer PCIe standard. The production status tells a similar story: Intel has discontinued the E-2276G, while AMD continues to produce the 3800XT.

Where Each One Wins

The AMD Ryzen 7 3800XT wins every head-to-head benchmark recorded in the database. Its multi-core advantage is overwhelming. In Cinebench R15 multi-core, it scores 2230 against 1205, a 46% lead. That margin comes directly from having 8 cores and 16 threads versus 6 cores and 12 threads, plus the efficiency of the 7 nm Zen 2 design. The Ryzen also wins in Geekbench multi-core with 8561 versus 6551, a 23.5% gap.

Single-core performance also favors AMD, but by a smaller margin. Cinebench R15 single-core shows 219 for the Ryzen 7 3800XT against 169 for the Xeon, a 22.8% difference. Geekbench single-core is closer: 1773 versus 1610, a 9.2% edge. The Xeon's higher 4.90 GHz boost clock helps it close the gap, but the Zen 2 architecture's IPC advantage still puts AMD ahead.

For the Intel Xeon E-2276G, the wins are not in raw performance but in platform features. ECC memory support is a genuine advantage for error-sensitive workstation workloads. Integrated graphics mean a display output is available without a discrete GPU. The lower 80 W TDP is also notable, though it must be weighed against the fact that the Xeon has fewer cores and a smaller cache.

The database's nearest rival data places the Xeon E-2276G alongside processors like the AMD Ryzen 7 PRO 1700 and Intel Xeon E-2286G, with average scores of 3613 and 3610 respectively. The Ryzen 7 3800XT, by contrast, is clustered with parts like the Intel Atom x7213RE and Intel Core i3-12300T, though those deltas are within 0.4%. This is an interesting quirk: the Xeon's average score is slightly higher, but its head-to-head losses to the Ryzen are decisive.

Head-to-Head Benchmarks

The database records four direct comparisons between these two processors. AMD wins all four, but the margins vary considerably.

Cinebench R15 Multi-Core: The Ryzen 7 3800XT scores 2230, the Xeon E-2276G scores 1205. That is a 46% difference, the largest gap in the set. This is the clearest demonstration of the core count advantage. Eight Zen 2 cores outperform six Coffee Lake cores by a wide margin in a fully threaded render workload.

Cinebench R15 Single-Core: The Ryzen 7 3800XT takes this at 219 versus 169, a 22.8% lead. Even with the Xeon's higher 4.90 GHz boost, the Zen 2 architecture's per-core efficiency wins out. This is a notable result because single-core performance is often where Intel traditionally held an advantage.

Geekbench Multi-Core: AMD wins again with 8561 against 6551, a 23.5% margin. The pattern holds: more cores and better scaling give the Ryzen a substantial lead in multi-threaded synthetic workloads.

Geekbench Single-Core: The closest contest of the set. The Ryzen 7 3800XT scores 1773, the Xeon E-2276G scores 1610, a 9.2% gap. This shows that the Xeon's boost clock can partially compensate for older architecture, but not fully.

The Ryzen 7 3800XT also has additional benchmark records in the database that the Xeon does not share. These include 3DMark results: 6307 for 16 threads, 6294 for max threads, 4743 for 8 threads, 2795 for 4 threads, 1475 for 2 threads, and 748 for single thread. These figures reinforce the scaling picture, with the max-threads score nearly matching the 16-thread score, indicating effective use of the full thread count.

The Intel Xeon E-2276G has its own benchmark records, including Cinebench R20 multi-core at 5021, single-core at 708, Cinebench R23 multi-core at 11957, and single-core at 1688. These are respectable numbers, but no R20 or R23 scores are recorded for the Ryzen 7 3800XT in this database, so direct comparison is limited to the four shared tests.

The average benchmark score tells a slightly different story. The Xeon E-2276G averages 3614, which is higher than the Ryzen 7 3800XT's 3515. This reflects the different benchmark sets available for each processor. The Xeon's nearest rivals include the AMD Ryzen 7 PRO 1700 at 3613, the Intel Xeon E-2286G at 3610, the Intel Xeon E5-2678 v3 at 3608, and the AMD Ryzen 7 2700E at 3603, all within 0.3%. The Ryzen 7 3800XT's nearest rivals are the Intel Atom x7213RE at 3520, the Intel Core i3-12300T at 3525, the Intel Xeon E-2176G at 3502, and the Intel Xeon W-2135 at 3530, all within 0.4%.

In the shared head-to-head tests, the data is unambiguous: the AMD Ryzen 7 3800XT is the faster processor. The Intel Xeon E-2276G retains relevance through ECC support, integrated graphics, and a lower TDP, but on raw benchmark performance, it loses every recorded contest.
