Intel Core i3-12100F vs Intel Xeon Gold 6348 Comparison

The Verdict

The benchmark database presents a stark contrast between these two Intel processors. The Intel Core i3-12100F and the Intel Xeon Gold 6348 serve entirely different purposes, and the recorded data leaves no ambiguity about their respective strengths. The Xeon Gold 6348 wins every single head-to-head benchmark recorded, taking all six tests, while the Core i3-12100F secures zero wins. This is not a close competition; it is a demonstration of what happens when a desktop quad-core processor is placed against a server-class 28-core behemoth.

The Xeon Gold 6348 is the clear choice for workloads that scale with core count and memory bandwidth. Its 28 cores and 56 threads dominate multi-threaded tasks, as shown by its Cinebench R23 multi-core score of 44,066, which is 73.1% higher than the Core i3-12100F's 11,860. The same 73.1% delta appears across all Cinebench versions, indicating a consistent and massive advantage in parallel processing. This processor is for server racks, virtualization hosts, and heavy computational tasks where raw throughput is paramount.

The Core i3-12100F, while losing every direct comparison, still occupies a valid position. Its single-core performance, though also beaten by the Xeon, is not catastrophic. The Xeon wins single-threaded tests by the same 73.1% margin, but the Core i3's lower power envelope of 58 watts TDP versus 235 watts makes it a sensible pick for compact desktop builds where energy efficiency and modest multi-threading are adequate. The data suggests the Core i3 is for users who need a capable, low-power desktop processor, while the Xeon is for professionals who need maximum throughput and do not prioritize power consumption.

The percentiles reinforce the divide. The Core i3-12100F sits at the 68th percentile among all CPUs, while the Xeon Gold 6348 sits at the 67th percentile. This similarity in overall standing is misleading, as the average benchmark scores tell a different story: the Core i3 averages 13,494, while the Xeon averages 12,746. The Xeon's lower average is likely due to its benchmark suite being limited to Cinebench tests, whereas the Core i3 has a broader set including Geekbench and Passmark tests where its single-threaded efficiency shines relative to its core count. For the target use case of each chip, the verdict is clear: the Xeon for servers, the Core i3 for desktops.

Architecture Differences

The two processors come from different architectural lineages within Intel's 10 nm generation. The Core i3-12100F is based on Alder Lake, specifically the Alder Lake-S die, which is a hybrid architecture designed for desktop performance. The Xeon Gold 6348 is based on Ice Lake, specifically the Ice Lake-SP die, which is a server-focused architecture optimized for scalability and reliability.

The core designs differ significantly. The Core i3-12100F has 4 cores and 8 threads, while the Xeon Gold 6348 has 28 cores and 56 threads. The Core i3's cache layout is 80 KB of L1 per core and 1.25 MB of L2 per core, with 12 MB of shared L3 cache. The Xeon's cache is 64 KB of L1 per core and 1 MB of L2 per core, with a substantially larger 42 MB of shared L3 cache. The Xeon's larger L3 cache reflects its need to feed 28 cores, while the Core i3's smaller cache is sufficient for its 4-core design.

Memory support is another key architectural divider. The Core i3-12100F supports both DDR4 and DDR5 memory in a dual-channel configuration. The Xeon Gold 6348 supports only DDR4, but it does so across an eight-channel memory bus, yielding a recorded memory bandwidth of 204.8 GB/s. The Xeon also supports ECC memory, which is absent on the Core i3. PCIe capabilities differ as well: the Core i3 offers Gen 5 with 16 lanes, while the Xeon offers Gen 4 with 64 lanes. The Xeon's lane count is designed for massive I/O expansion in server environments.

The market segments are explicit in the data: the Core i3 is classified as Desktop, while the Xeon is classified as Server/Workstation. The Xeon's production status is Active, as is the Core i3's. The Xeon has a release date of April 5, 2021, while the Core i3 has no recorded release date.

Specification Differences

The specification table reveals a clear separation in every major category. The Core i3-12100F has 4 cores and 8 threads, while the Xeon Gold 6348 has 28 cores and 56 threads. Base clocks differ: the Core i3 runs at 3.30 GHz, the Xeon at 2.60 GHz. Boost clocks also differ: the Core i3 reaches 4.30 GHz, the Xeon reaches 3.50 GHz. The Core i3 has the higher clock speeds, but the Xeon has far more cores.

Thermal design power is a major differentiator. The Core i3-12100F has a TDP of 58 watts, while the Xeon Gold 6348 has a TDP of 235 watts. This is a 4-fold difference in power consumption, directly reflecting the Xeon's larger core count and server-oriented design. The sockets are incompatible: the Core i3 uses Intel Socket 1700, the Xeon uses Intel Socket 4189.

Cache specifications differ in both size and distribution. The Core i3 has 80 KB of L1 per core and 1.25 MB of L2 per core, with 12 MB of shared L3. The Xeon has 64 KB of L1 per core and 1 MB of L2 per core, with 42 MB of shared L3. The Xeon's total L3 is 3.5 times larger than the Core i3's.

Memory support is a clear split. The Core i3 supports DDR4 and DDR5, while the Xeon supports only DDR4. The memory bus is dual-channel on the Core i3 and eight-channel on the Xeon. The Xeon has a recorded memory bandwidth of 204.8 GB/s, while the Core i3 has no such figure. ECC memory is supported on the Xeon but not on the Core i3. PCIe generations and lane counts differ: the Core i3 has Gen 5 with 16 lanes, the Xeon has Gen 4 with 64 lanes.

Neither processor has an unlocked multiplier. The part numbers are distinct: the Core i3 is SRL63, the Xeon is SRKHPCD8068904572204.

Head-to-Head Benchmarks

The head-to-head benchmark data is entirely one-sided, with the Xeon Gold 6348 winning all six recorded tests. The deltas are remarkably consistent across every test, all showing a 73.1% advantage for the Xeon. This uniformity suggests that the performance gap is structural, driven by the core count difference rather than by any specific workload characteristic.

In Cinebench R15 multi-core, the Xeon scores 4,441 against the Core i3's 1,195, a 73.1% difference. The single-core R15 test shows the Xeon at 626 against the Core i3's 168, again a 73.1% delta. Moving to Cinebench R20, the multi-core test has the Xeon at 18,507 and the Core i3 at 4,981. The single-core R20 test has the Xeon at 2,612 and the Core i3 at 703. Both show the same 73.1% gap.

Cinebench R23 continues the pattern. The multi-core test shows the Xeon at 44,066 and the Core i3 at 11,860, a 73.1% difference. The single-core R23 test shows the Xeon at 6,221 and the Core i3 at 1,674, also 73.1% apart. The consistency of this delta across six different tests, spanning both multi-core and single-core workloads, indicates that the Xeon's advantage is not workload-dependent but rather a fundamental property of its architecture.

The Core i3's highest recorded benchmark scores come from its broader suite. Its Geekbench multi-core score is 7,252, and its single-core score is 1,932. Its Passmark multi-thread score is 14,015, and its single-thread score is 3,444. These figures are not directly comparable to the Xeon, which only has Cinebench scores in the database, but they show that the Core i3 is a capable desktop processor in its own right.

Where Each One Wins

The Xeon Gold 6348 wins in every scenario that requires parallel processing. Its 28 cores and 56 threads, combined with 42 MB of shared L3 cache and eight-channel memory support, make it the dominant choice for server virtualization, database hosting, scientific computing, and any workload that can utilize more than a handful of threads. The 73.1% advantage in Cinebench multi-core tests across all three versions (R15, R20, R23) demonstrates that the Xeon scales effectively with thread count. The recorded memory bandwidth of 204.8 GB/s further solidifies its position for memory-intensive tasks like large-scale data processing.

The Xeon also wins in single-core performance, despite the Core i3's higher boost clock. The Xeon's single-core Cinebench R23 score of 6,221 beats the Core i3's 1,674 by the same 73.1% margin. This suggests that the Xeon's core architecture is more efficient per clock, or that the benchmark environment favors the server platform. For users who need ECC memory support, the Xeon is the only option, as the Core i3 does not support it.

The Core i3-12100F wins in scenarios where power consumption and platform cost are the primary constraints. Its 58 watt TDP is a fraction of the Xeon's 235 watts, making it suitable for compact desktop builds, home theater PCs, and entry-level gaming rigs. Its support for both DDR4 and DDR5 memory provides flexibility for builders, and its PCIe Gen 5 support with 16 lanes is modern for desktop use. The Core i3's average benchmark score of 13,494 is higher than the Xeon's 12,746, which reflects its strong showing in the broader benchmark suite, particularly in single-threaded tests like Passmark single-thread (3,444) and Geekbench single-core (1,932).

The data does not support any scenario where the Core i3 beats the Xeon in direct head-to-head benchmarks. However, the Core i3's lower TDP, smaller die size of 163 mm², and desktop market segment make it the logical choice for consumer systems. The Xeon's server market segment, eight-channel memory, and ECC support make it the only choice for enterprise deployments. The decision is not about which is better in absolute terms, but which fits the intended use case. The Xeon wins every benchmark; the Core i3 wins on efficiency and desktop suitability.
