Where Each One Wins

Looking at the head-to-head benchmark data, the Intel Xeon E5-2609 v3 wins all six recorded comparisons. However, the margins are surprisingly small.

The most decisive win for the Xeon is in Cinebench R15 multi-core, with a score of 386 against the Pentium's 383, a delta of 0.8%. In Cinebench R20 multi-core, the Xeon scores 227 versus 225, again a 0.9% lead. The R23 multi-core test shows a similar story: 541 versus 536, a 0.9% advantage for the Xeon.

The single-core tests are even closer. In Cinebench R15 single-core, the Xeon scores 54 and the Pentium scores 54, resulting in a tie. The Xeon takes the win in R20 single-core with 227 versus 225, a 0.9% gap. In R23 single-core, the Xeon posts 541 against the Pentium's 536, another 0.9% win.

The average benchmark score for the Xeon is 1109, and the Pentium Gold G6500 sits at 1099 in the database, a 0.9% difference. The Xeon sits at the 31st percentile of all CPUs, while the Pentium sits at the 31st percentile too.

Architecture Differences

The architectural lineage clearly separates these two processors. The Intel Xeon E5-2609 v3 uses the Haswell-EP microarchitecture, codenamed Haswell-EP, and is built for the Intel Socket 2011-3. It belongs to the Xeon E5 (Haswell) generation.

The Pentium 6805, in contrast, uses the Ice Lake microarchitecture, codenamed Ice Lake-Y, and fits the Intel BGA 1526 socket. It is part of the Pentium (Sunny Cove-Y) generation. The process nodes also differ: the Xeon uses a 22 nm process, the Pentium uses a more advanced 10 nm node.

Cache structures follow their differing roles. The Xeon has a 15 MB shared L3 cache, with 64 KB L1 and 256 KB L2 per core. The Pentium has a smaller 4 MB shared L3, with 80 KB L1 and 256 KB L2 per core.

Memory support is a key divider. The Xeon supports DDR4 memory across a quad-channel bus with a memory bandwidth of 51.2 GB/s and has ECC memory enabled. The Pentium supports DDR4 on a dual-channel bus with 51.2 GB/s bandwidth and no ECC.

PCIe support also differs: the Xeon implements Gen 3 with 40 lanes CPU-only, while the Pentium is also Gen 3. The Xeon offers no integrated graphics, while the Pentium includes UHD Graphics with 32 execution units.

Head-to-Head Benchmarks

The benchmark suite pits the Xeon E5-2609 v3 against the Pentium 6805 across all six Cinebench tests. The Xeon takes every round, but the margins are consistently slim.

In Cinebench R15 multi-core, the Xeon records 386 points to the Pentium's 383, a 0.8% advantage. The single-core R15 test is a dead heat: both chips register 54 points. The Xeon wins the R20 multi-core test 227 to 225, a 0.9% gap. In R20 single-core, the Xeon scores 227 and the Pentium scores 225, again a 0.9% win.

The R23 multi-core test shows the Xeon with 3836 points and the Pentium with 3801, another 0.9% margin. The single-core R23 test repeats the pattern: 541 for the Xeon against 536 for the Pentium, a 0.9% lead.

The average benchmark score in the database places the Xeon at 1109, while the Pentium Gold G6500 sits at 1098. The Xeon's percentile rank among all CPUs is 31, and the Pentium's is 31. These are close performers, with the Xeon holding a slim, consistent edge in every generated workload. The largest win for the Xeon is the R15 multi-core test, where the extra cores and threads allow it to pull ahead by nearly a full point. The single-core tests are extremely tight, with the two chips essentially trading blows within a single percentage point.

The data shows a clear picture: the Xeon E5-2609 v3 is the faster processor in this pairing, but its advantage is narrow, typically under 1% in aggregate. The Pentium 6805, boosted by higher base clocks and a more modern process node, keeps the gap remarkably small despite having only a third of the core count. This makes the Pentium a compelling, efficiency-focused design, while the Xeon remains the performance leader. The Xeon wins six out of six tests, with the largest margin being 0.9% in the Cinebench R20 and R23 multi-core tests.
