Intel Core i3-10325 vs Intel Xeon E5-4620 v3 Comparison

The Verdict

The benchmark data presents an unusually clear hierarchy between these two Intel processors. The Intel Xeon E5-4620 v3 wins all six recorded head-to-head Cinebench comparisons, taking both single-core and multi-core tests across R15, R20, and R23. The margins are consistent, ranging from 2.3% to 2.4% in favor of the Xeon. The average benchmark score for the Xeon E5-4620 v3 is 2587, while the Core i3-10325 averages 2530, a difference of roughly 2.3% overall.

Despite the Xeon's sweep, the Core i3-10325 is not a weak performer in absolute terms. Both processors sit at the 49th percentile among all CPUs in the database, meaning they occupy the same performance tier. The real distinction lies in the platform and feature set. The Xeon E5-4620 v3 targets server and workstation deployments with support for ECC memory, quad-channel DDR4, 40 PCIe Gen 3 lanes, and a 105 W TDP. The Core i3-10325 is a desktop part with a 65 W TDP, dual-channel memory, 16 PCIe lanes, and integrated UHD Graphics 630. It also carries a launch MSRP of $154, which is substantially below the Xeon's launch MSRP of $1668. The data suggests the Xeon is for systems requiring enterprise features and maximum memory bandwidth, while the Core i3 is for standard desktop builds where its higher clocks and lower power envelope matter more.

The Xeon E5-4620 v3 is the correct choice for existing Socket 2011-3 platforms, workloads that can use 10 cores and 20 threads, or any environment requiring ECC memory and quad-channel bandwidth. The Core i3-10325 is the correct choice for Socket 1200 desktop builds where integrated graphics are useful, power consumption is a concern, and the 4-core, 8-thread configuration is sufficient. Neither processor offers a meaningful performance advantage over the other based on Cinebench results, so the platform and feature requirements will typically decide the purchase.

Where Each One Wins

The Xeon E5-4620 v3 wins every benchmark in the recorded head-to-head set. In Cinebench R15 multi-core, it scores 901 against 881, a 2.3% lead. Single-core R15 shows 127 against 124, a 2.4% margin. The pattern repeats in R20 multi-core (3757 vs 3673, 2.3%) and R20 single-core (530 vs 518, 2.3%). R23 multi-core sees 8946 against 8747, another 2.3% gap, and R23 single-core finishes at 1263 vs 1234, a 2.4% difference. The Xeon is therefore the winner in every measured category, but the margins are narrow enough that real-world application performance will likely be comparable.

The Core i3-10325 has no benchmark wins in this dataset, but it does hold advantages that are not captured in Cinebench scores. Its base clock of 3.90 GHz and boost clock of 4.70 GHz are far higher than the Xeon's 2.00 GHz base and 2.60 GHz boost. For lightly threaded workloads that are not represented by these synthetic tests, the Core i3's clock advantage could translate to faster response times. The Core i3 also includes UHD Graphics 630, so systems without a discrete GPU can still produce display output. The Xeon has no integrated graphics. The Core i3's 65 W TDP makes it easier to cool in compact desktop chassis, while the Xeon's 105 W TDP requires more substantial thermal solutions.

The Xeon wins on memory bandwidth. Its quad-channel DDR4 configuration provides 59.7 GB/s, versus 42.7 GB/s for the Core i3's dual-channel setup. For memory-intensive server workloads such as virtualization or large in-memory databases, that bandwidth advantage is significant even if Cinebench does not show it. The Xeon also supports ECC memory, which the Core i3 does not, making the Xeon the only option here for error-correcting memory in critical systems.

Architecture Differences

The Xeon E5-4620 v3 is built on Intel's 22 nm process with 2,600 million transistors on a 356 mm² die. Its architecture is Haswell, specifically the Haswell-EP variant used in Xeon E5 server processors. It has 10 cores and 20 threads, with a base clock of 2.00 GHz and a boost clock of 2.60 GHz. The cache hierarchy consists of 64 KB of L1 per core, 256 KB of L2 per core, and 25 MB of shared L3 cache. The memory controller supports DDR4 in a quad-channel configuration, delivering 59.7 GB/s of bandwidth, and ECC memory is supported. PCIe connectivity is Gen 3 with 40 lanes from the CPU. The TDP is 105 W, and the socket is Intel Socket 2011-3. This processor was released in 2015 and is now end-of-life.

The Core i3-10325 is built on Intel's 14 nm process and uses the Comet Lake architecture, specifically Comet Lake-R. It has 4 cores and 8 threads, with a base clock of 3.90 GHz and a boost clock of 4.70 GHz. Cache sizes are 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3 cache. Memory support is DDR4 in a dual-channel configuration, providing 42.7 GB/s of bandwidth, and ECC memory is not supported. The PCIe implementation is Gen 3 with 16 lanes from the CPU. Integrated graphics are present in the form of UHD Graphics 630. The TDP is 65 W, and the socket is Intel Socket 1200. This processor was released in 2021 and remains active in production.

The core count difference is the most obvious architectural split: 10 cores and 20 threads versus 4 cores and 8 threads. The Xeon also has more than three times the L3 cache (25 MB vs 8 MB). The Core i3 compensates with much higher clock speeds, nearly double the base clock and almost double the boost clock. The die size and transistor data are only recorded for the Xeon, as Intel has not listed those figures for the Core i3 in the database. Both processors use DDR4 memory, but the Xeon's quad-channel controller gives it a 17 GB/s bandwidth advantage over the Core i3's dual-channel controller.

Another notable difference is the market segment. The Xeon is classified as a server and workstation part, while the Core i3 is a desktop part. The Xeon supports ECC memory and 40 PCIe lanes, both of which are typical for enterprise platforms. The Core i3 supports no ECC and only 16 PCIe lanes. The Core i3 includes integrated graphics, which the Xeon lacks entirely. The production status also differs: the Xeon is end-of-life, while the Core i3 is active, meaning the Xeon is no longer in active production.

Head-to-Head Benchmarks

The head-to-head dataset covers six Cinebench tests, and the Xeon E5-4620 v3 wins each one. The largest margins appear in the single-core tests, where the Xeon leads by 2.4% in both Cinebench R15 and R23. In R15 single-core, the Xeon scores 127 against 124. In R23 single-core, the Xeon scores 1263 against 1234. The R20 single-core test shows a slightly smaller margin of 2.3%, with scores of 530 and 518.

The multi-core tests all show a 2.3% lead for the Xeon. In Cinebench R15 multi-core, the Xeon scores 901 and the Core i3 scores 881. In R20 multi-core, the Xeon scores 3757 and the Core i3 scores 3673. In R23 multi-core, the Xeon scores 8946 and the Core i3 scores 8747. The consistency of these margins across different Cinebench versions suggests the performance difference is stable and not specific to any particular rendering workload.

Looking at the nearest rivals in the database provides additional context. The Xeon E5-4620 v3 has an average benchmark score of 2587, placing it within 0.3% of the AMD Ryzen 3 PRO 4355GE, which averages 2596, and within 0.5% of the AMD Ryzen 9 4900HS, which averages 2573. It also sits nearly exactly level with the Intel Xeon E-2174G, which averages 2588, and it trails the Intel Core i7-8850H, which averages 2604, by 0.7%. The Core i3-10325, with an average score of 2530, is 0.1% above the Intel Xeon E-2244G, 0.7% above the Intel Xeon E-2144G, and 0.8% above the Intel Xeon E5-2643 v3. It trails the Intel Xeon E5-1650 v3, which averages 2545, by 0.6%.

These rival comparisons confirm that both processors sit in the same performance neighborhood despite their architectural differences. The Xeon's 10-core, 20-thread configuration with 25 MB of L3 cache and quad-channel memory does not produce a decisive Cinebench advantage over the Core i3's 4-core, 8-thread design with 8 MB of L3 cache and dual-channel memory. The Core i3's much higher clocks, 3.90 GHz base and 4.70 GHz boost, largely offset the Xeon's core and cache advantages in these particular workloads. The Xeon's wins are real but narrow, and the data does not support a claim of substantial performance superiority in either direction. The choice between these two processors should be driven by platform requirements, memory needs, and feature support rather than by raw Cinebench scores.
