Intel Core i3-9100 vs Intel Xeon E5-4610 v3 Comparison

The database presents an unusual pairing: a modest desktop quad-core from Intel's Coffee Lake lineup against a decade-old server workhorse. The Intel Core i3-9100 and the Intel Xeon E5-4610 v3 could hardly be more different in design intent, yet their aggregate benchmark positions are nearly identical, with average scores of 1806 and 1777 respectively and percentile placements of 42 and 41 against all CPUs in the database. That near-parity in the averages hides a consistent pattern in the individual tests, and unpacking that contradiction is the interesting part of this comparison.

Head-to-Head Benchmarks

The recorded data shows a clean sweep: the Xeon E5-4610 v3 wins all six head-to-head tests, and by remarkably uniform margins.

In Cinebench R15, the Xeon scores 619 in multi-core versus 566 for the i3-9100, a gap of 8.6 percent, and 87 versus 79 in single-core, a 9.2 percent difference. Cinebench R20 repeats the story almost exactly: 2580 against 2361 multi-core (8.5 percent) and 364 against 333 single-core (again 8.5 percent). Cinebench R23 lands on the same numbers, 6144 versus 5622 multi-core and 867 versus 793 single-core, both 8.5 percent apart.

Two things stand out here. First, the single-core margins are nearly identical to the multi-core margins, roughly eight to nine percent across the board. Second, the multi-core gap is strikingly small given the hardware disparity. The Xeon has 10 cores and 20 threads; the i3 has 4 cores and 4 threads. Five times the cores, twice the threads, and yet only an 8.5 percent lead in R23 multi-core. The data implies the Xeon's per-thread throughput is heavily constrained, most plausibly by its base clock of 1.70 GHz and its Haswell-era architecture. The i3-9100, by contrast, boosts to 4.20 GHz from a 3.60 GHz base on a newer 14 nm Coffee Lake design, and still it trails in every single-threaded test by about nine percent, which raises its own questions about how the Xeon achieves that single-core result at such a modest clock.

Geekbench data exists only for the i3-9100 (3403 multi-core, 1290 single-core), so no direct comparison is possible there; the head-to-head record rests on the Cinebench suite.

Context from the rival data reinforces how closely matched these two are in aggregate terms. The i3-9100's average score of 1806 sits within half a percent of the Intel Core i3-9320 (1808, delta -0.1), the AMD Ryzen 5 PRO 4650U (1810, delta -0.2), the Intel Xeon E5-1620 v4 (1802, delta 0.2), and the Intel Core i5-6600K (1816, delta -0.5). The Xeon's 1777 average is similarly sandwiched, between the AMD Ryzen 3 PRO 1300 (1778, delta -0.1), the Intel Xeon E5-2637 v3 (1773, delta 0.2), the Intel Core i7-4870HQ (1769, delta 0.4), and the AMD Ryzen 3 3200GE (1787, delta -0.6). Both CPUs occupy the same performance neighborhood, roughly the low 40th percentile of all recorded CPUs.

Architecture Differences

The architectural gap between these parts spans two Intel generations and two market segments.

The i3-9100 is a Coffee Lake Refresh desktop chip built on Intel's 14 nm process, with a die size of 126 mm². The Xeon E5-4610 v3 is a Haswell-EP server chip on the older 22 nm node, with a much larger 356 mm² die and 2,600 million transistors. The i3's transistor count is not recorded, so no direct density comparison is possible, but the die size difference alone illustrates how much silicon the server part dedicates to its broader core and cache structure.

Core and cache configurations diverge sharply. The i3 pairs 4 cores with 4 threads, meaning no SMT, while the Xeon runs 10 cores with 20 threads. Per-core L1 (64 KB) and L2 (256 KB) caches are identical between the two, but the shared L3 differs enormously: 6 MB on the i3 versus 25 MB on the Xeon, more than four times as much last-level cache.

Memory subsystems also differ. Both support DDR4 with ECC, which is notable for the i3 since ECC on a desktop part is uncommon. But the Xeon's quad-channel bus delivers 51.2 GB/s of bandwidth against the i3's dual-channel 38.4 GB/s. PCIe follows the same pattern: the Xeon exposes 40 Gen 3 lanes from the CPU, the i3 just 16.

Clock behavior is where the i3 claws back ground. It runs a 3.60 GHz base with a 4.20 GHz boost, unlocked multiplier absent in both chips, while the Xeon lists only a 1.70 GHz base with no recorded boost clock. TDP figures are 65 W for the i3 and 105 W for the Xeon.

Other differences: the i3 includes UHD Graphics 630 integrated graphics; the Xeon has none. Sockets are incompatible, Intel Socket 1151 versus Intel Socket 2011-3. Launch MSRPs were $122 for the i3-9100 and $1219 for the Xeon E5-4610 v3. Release dates were 2018 for the i3 and 2015 for the Xeon, and both are now end-of-life products.

The Verdict

Strictly from the recorded data, the Xeon E5-4610 v3 is the faster CPU in every benchmark run, by a consistent eight to nine percent. If the question is purely "which scores higher," the answer is the Xeon, six tests to zero.

But the verdict deserves nuance. The Xeon's advantage is small in absolute terms despite having two and a half times the cores and twice the threads. That return-per-core is poor, and the data implies the i3-9100 extracts far more throughput from each of its four cores. For any workload that leans on a few fast threads rather than many slow ones, the eight to nine percent single-core gap still favors the Xeon, so the data does not hand the i3 a single win, yet the margin is narrow enough that platform considerations (integrated graphics, socket, memory configuration) plausibly matter more than the raw score difference.

Both chips sit in the 41st to 42nd percentile of all CPUs, meaning neither is a performance outlier by modern database standards. The choice, per the data, comes down to what surrounds the CPU: quad-channel bandwidth and massive L3 cache on one side, integrated graphics and a much newer architecture on the other.

Where Each One Wins

The data assigns every benchmark win to the Xeon E5-4610 v3, so a use-case split must be built on capacity rather than score alone. The Xeon's wins on paper, all six Cinebench tests, technically make it the better rendering and multi-threaded compute choice. Yet the more telling signal is what its hardware enables beyond these tests: 20 threads for parallel server workloads, 25 MB of L3 for large working sets, 40 PCIe lanes for expansion cards, and 51.2 GB/s of quad-channel memory bandwidth for data-intensive tasks. Those attributes are not reflected in the Cinebench margins, which suggests the recorded tests may understate the Xeon's advantage in throughput-heavy environments.

The i3-9100 wins nothing in the benchmark table, but it wins elsewhere in the spec sheet: integrated UHD Graphics 630 means it runs without a discrete GPU, its 4.20 GHz boost clock delivers fast per-thread response, and its Socket 1151 desktop platform is a different class of machine than the Xeon's Socket 2011-3 server boards. Its own rival set (Core i3-9320, Ryzen 5 PRO 4650U, Xeon E5-1620 v4, Core i5-6600K) confirms it competes as an ordinary desktop CPU, not a workstation part.

Specification Differences

• Cores/Threads: 4 cores, 4 threads (i3-9100) versus 10 cores, 20 threads (Xeon E5-4610 v3)
• Base Clock: 3.60 GHz versus 1.70 GHz; the Xeon has no recorded boost clock, the i3 boosts to 4.20 GHz
• TDP: 65 W versus 105 W
• Socket: Intel Socket 1151 versus Intel Socket 2011-3
• Architecture: Coffee Lake versus Haswell-EP
• Process Node: 14 nm versus 22 nm
• Die Size: 126 mm² versus 356 mm² (the Xeon records 2,600 million transistors; no figure exists for the i3)
• L3 Cache: 6 MB shared versus 25 MB shared
• Memory Bus: Dual-channel versus quad-channel; bandwidth 38.4 GB/s versus 51.2 GB/s (both DDR4 with ECC)
• PCIe: Gen 3, 16 lanes versus Gen 3, 40 lanes
• Integrated Graphics: UHD Graphics 630 versus none
• Market Segment: Desktop versus Server/Workstation
• Release Date: 2018 versus 2015; both end-of-life
• Launch MSRP: $122 versus $1219
• Part Number: SRCZV versus SR22S; both have locked multipliers

The final picture is a statistical tie in aggregate (1806 versus 1777 average scores) resolved in the Xeon's favor in every individual test, while the i3-9100 counters with a modern platform, integrated graphics, and per-core efficiency that its rival cannot match. The data leaves one open question: whether a test suite exercising all 20 threads and the full 51.2 GB/s of memory bandwidth would widen the Xeon's lead beyond the eight to nine percent Cinebench shows.
