Architecture Differences

The Intel Core i5-1155G7 and the Intel Xeon E5-4620 v3 come from entirely different design generations and market segments. The Core i5-1155G7 is a mobile processor built on Tiger Lake-U architecture, using a 10 nm process node from Intel. Its die size measures 144 mm². The Xeon E5-4620 v3, by contrast, is a server and workstation chip based on Haswell-EP architecture, manufactured on a 22 nm process with a die size of 356 mm² and 2,600 million transistors. The process node difference alone explains much of the efficiency and clock speed disparity between the two.

Core counts differ substantially. The Core i5-1155G7 provides 4 cores and 8 threads, while the Xeon E5-4620 v3 offers 10 cores and 20 threads. This gives the Xeon a 2.5x advantage in raw thread count, which directly supports its multi-core benchmark leads. Cache hierarchies also reflect their different roles. The Core i5-1155G7 features 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 8 MB of shared L3 cache. The Xeon E5-4620 v3 has 64 KB of L1 per core, 256 KB of L2 per core, and a much larger 25 MB shared L3 cache.

Memory architecture diverges sharply. The Core i5-1155G7 uses a dual-channel memory bus supporting DDR4 and LPDDR4X, with no ECC capability. The Xeon E5-4620 v3 uses a quad-channel memory bus with DDR4 support, a recorded memory bandwidth of 59.7 GB/s, and ECC memory support. PCIe connectivity also differs: the Core i5 provides PCIe Gen 4 with 16 lanes, while the Xeon offers PCIe Gen 3 with 40 lanes.

Integrated graphics is another major differentiator. The Core i5-1155G7 includes Iris Xe-LP Graphics G7 with 80 execution units, making it suitable for systems without a discrete GPU. The Xeon E5-4620 v3 has no integrated graphics at all, which is typical for server processors that assume a separate graphics solution. The socket types are incompatible: the Core i5 uses Intel BGA 1449, while the Xeon uses Intel Socket 2011-3. The Xeon also carries a significantly higher launch MSRP of $1668, compared to $309 for the Core i5.

Head-to-Head Benchmarks

The database records six head-to-head comparisons, all of which favor the Intel Xeon E5-4620 v3. The results are consistent across every Cinebench version tested. In Cinebench R15 multi-core, the Xeon scores 901 against the Core i5's 822, a delta of 8.8% in the Xeon's favor. The single-core R15 test shows a slightly larger gap of 9.4%, with scores of 127 for the Xeon and 115 for the Core i5.

Cinebench R20 follows the same pattern. The multi-core test gives the Xeon 3757 points versus 3425 for the Core i5, again an 8.8% difference. In single-core R20, the Xeon scores 530 and the Core i5 scores 483, a delta of 8.9%. Cinebench R23 multi-core results show the Xeon at 8946 and the Core i5 at 8155, maintaining the consistent 8.8% gap. The R23 single-core test rounds out the set with 1263 for the Xeon and 1151 for the Core i5, a 8.9% difference.

The consistency of these margins is notable. Across all multi-core tests, the delta is exactly 8.8%, and across single-core tests, the delta is either 8.9% or 9.4%. This suggests the Xeon's advantage is structural rather than workload-dependent. The Xeon's 10-core, 20-thread configuration clearly drives the multi-core results, but its single-core lead indicates that even per-thread performance favors the older Haswell design in these specific Cinebench workloads.

The Core i5-1155G7's higher boost clock of 4.50 GHz compared to the Xeon's 2.60 GHz does not translate into a single-core win. The Xeon's single-core scores are consistently higher by roughly 9%, which is a counterintuitive result given the clock speed disparity. The database shows no benchmark where the Core i5 takes the lead, with all six comparisons recorded as wins for the Xeon E5-4620 v3.

Specification Differences

The two processors differ across nearly every major specification category. Core and thread counts: the Core i5-1155G7 has 4 cores and 8 threads, while the Xeon E5-4620 v3 has 10 cores and 20 threads. Base clocks are 2.50 GHz for the Core i5 and 2000.00 MHz for the Xeon, with boost clocks of 4.50 GHz and 2.60 GHz respectively. The Core i5 has a TDP of 28 watts, while the Xeon draws 105 watts.

Process node and die size differ: 10 nm and 144 mm² for the Core i5, versus 22 nm and 356 mm² for the Xeon. The Xeon's transistor count is recorded at 2,600 million, while no transistor count is listed for the Core i5. Cache configurations are distinct: the Core i5 has 80 KB L1 and 1.25 MB L2 per core with 8 MB shared L3; the Xeon has 64 KB L1 and 256 KB L2 per core with 25 MB shared L3.

Memory support shows the Core i5 accepting DDR4 and LPDDR4X over a dual-channel bus, while the Xeon accepts DDR4 over a quad-channel bus with 59.7 GB/s bandwidth. ECC memory is available only on the Xeon. PCIe generations and lane counts differ: Gen 4 with 16 lanes for the Core i5, Gen 3 with 40 lanes for the Xeon. Integrated graphics exist only on the Core i5, with Iris Xe-LP Graphics G7 80EU. The Xeon has no integrated graphics.

Socket types are incompatible: Intel BGA 1449 for the Core i5 and Intel Socket 2011-3 for the Xeon. The production status also differs, with the Core i5 Active and the Xeon End-of-life. Release dates are separated by roughly six years, with the Core i5 launching on 2021-05-30 and the Xeon on 2015-05-31. The launch MSRP is $309 for the Core i5 and $1668 for the Xeon.

The Verdict

The benchmark data is unambiguous: the Intel Xeon E5-4620 v3 outperforms the Intel Core i5-1155G7 in every recorded test. The Xeon wins all six head-to-head comparisons, with multi-core margins of 8.8% and single-core margins between 8.9% and 9.4%. For workloads that rely on sustained multi-threaded performance, the Xeon's 10 cores and 20 threads provide a clear advantage over the Core i5's 4 cores and 8 threads.

The Core i5-1155G7 does have meaningful advantages in other dimensions. Its 10 nm process node, 28-watt TDP, and integrated Iris Xe graphics make it suitable for compact mobile systems where power efficiency and GPU capability matter. Its 4.50 GHz boost clock is far higher than the Xeon's 2.60 GHz, and its PCIe Gen 4 support is newer than the Xeon's Gen 3. The Core i5 also remains in active production, while the Xeon is end-of-life.

However, the database's benchmark results indicate that the Core i5's modern architecture does not overcome the Xeon's core count advantage in Cinebench workloads. The Xeon's average benchmark score of 2587 also exceeds the Core i5's 2496, and its nearest rivals include the Intel Core i7-8850H and AMD Ryzen 9 4900HS, while the Core i5 sits near the Intel Core i5-9500T and Intel Xeon E5-2630 v3. Both chips occupy the 49th percentile among all CPUs, but the Xeon does so with a higher absolute score.

The choice between these processors depends on the use case. For a mobile system requiring integrated graphics, low power consumption, and modern connectivity, the Core i5-1155G7 is the only viable option, as the Xeon lacks integrated graphics and demands a server platform. For a server or workstation environment where ECC memory, quad-channel bandwidth, and maximum core count are priorities, the Xeon E5-4620 v3 is the stronger performer according to the recorded data. The Xeon's 25 MB of L3 cache and 59.7 GB/s memory bandwidth also support memory-heavy server workloads that the Core i5 cannot match. Buyers choosing strictly on benchmark performance should favor the Xeon; buyers prioritizing mobility and efficiency should select the Core i5.
