Intel Core i3-1210U vs Intel Xeon Gold 6348 Comparison

The Intel Core i3-1210U and Intel Xeon Gold 6348 occupy opposite ends of Intel’s product stack, yet their average benchmark scores are nearly identical. The Core i3-1210U is a 6-core mobile processor with a 9 W TDP, while the Xeon Gold 6348 is a 28-core server chip with a 235 W TDP. Despite the massive difference in core count and power envelope, the Xeon Gold 6348’s average benchmark score of 12,746 is only 0.4% behind the Core i3-1210U’s 12,795, placing both in the 67th and 68th percentiles of all CPUs respectively. This unusual proximity makes the head-to-head comparison less about raw score and more about workload suitability.

FAQ

Q: Which processor has the higher average benchmark score?

A: The Intel Core i3-1210U has a slightly higher average benchmark score of 12,795, compared to the Xeon Gold 6348’s 12,746. The delta between them is just 0.4%, making them statistically equivalent in aggregate performance.

Q: How do the two chips differ in core and thread counts?

A: The Xeon Gold 6348 has 28 cores and 56 threads, while the Core i3-1210U has 6 cores and 8 threads. This represents a 4.7x difference in core count and a 7x difference in thread count in favor of the Xeon.

Q: What are the single-thread performance characteristics of each?

A: The Xeon Gold 6348 wins every single-core benchmark in the head-to-head set, but the Core i3-1210U has a higher boost clock of 4.40 GHz versus the Xeon’s 3.50 GHz. The Xeon’s advantage comes from its higher base clock of 2.60 GHz and different microarchitecture.

Q: Which processor supports ECC memory?

A: Only the Xeon Gold 6348 supports ECC memory. The Core i3-1210U does not list ECC as a supported feature, which is typical for its mobile market segment.

Q: What is the difference in memory channel support?

A: The Xeon Gold 6348 uses eight-channel memory with a bandwidth of 204.8 GB/s, while the Core i3-1210U uses dual-channel memory. The Xeon also specifies DDR4-only support, whereas the Core i3 supports both DDR4 and DDR5.

Q: Which processor has integrated graphics?

A: The Core i3-1210U includes Intel UHD Graphics 64EU, while the Xeon Gold 6348 has no integrated graphics listed. This makes the Core i3 suitable for systems without a discrete GPU.

Where Each One Wins

The Xeon Gold 6348 is the clear winner for multi-threaded workloads, dominating all six head-to-head benchmark tests. In Cinebench R23 multi-core, it scores 44,066 versus the Core i3-1210U’s 8,413, a delta of -80.9%. The same pattern holds across Cinebench R15 and R20 multi-core tests, where the Xeon leads by identical -80.9% margins. This makes the Xeon the obvious choice for rendering, simulation, and other heavily parallel tasks that can utilize its 28 cores and 56 threads.

The Core i3-1210U, despite losing every head-to-head benchmark, has its own niche. Its 9 W TDP and mobile BGA 1781 socket make it suitable for thin-and-light laptops, while its integrated UHD Graphics 64EU eliminates the need for a separate GPU. The Core i3 also supports DDR5 memory, which the Xeon does not, and its higher 4.40 GHz boost clock provides a theoretical advantage in bursty, lightly-threaded workloads—though the Xeon’s superior single-core benchmark scores suggest the architecture matters more than raw clock speed.

For single-thread performance, the Xeon Gold 6348 wins all three Cinebench single-core tests, including a 6,221 score in R23 versus 1,187 for the Core i3. This is surprising given the Core i3’s higher boost clock, but the Xeon’s Ice Lake-SP architecture delivers better instructions-per-clock. The Core i3’s only potential edge is in power-constrained environments where the 235 W TDP of the Xeon is impractical.

Architecture Differences

The two processors are built on different Intel architectures. The Core i3-1210U uses Alder Lake-U, part of the Alder Lake family, while the Xeon Gold 6348 uses Ice Lake-SP. Both are manufactured on Intel’s 10 nm process node and by Intel’s foundry, but the microarchitecture designs diverge significantly. Alder Lake-U is a mobile-optimized design with a hybrid architecture approach, while Ice Lake-SP is a server-optimized design focused on scalability and memory bandwidth.

Cache hierarchies differ substantially. The Core i3-1210U has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 10 MB of shared L3 cache. The Xeon Gold 6348 has 64 KB of L1 per core, 1 MB of L2 per core, and 42 MB of shared L3 cache. The Xeon’s larger L3 cache is 4.2x bigger, which benefits server workloads with large working sets. The Core i3’s larger per-core L1 and L2 caches suggest better per-thread cache locality.

The socket and platform also differ completely. The Core i3 uses Intel BGA 1781, a soldered mobile socket, while the Xeon uses Intel Socket 4189, a server socket designed for multi-socket configurations. The Xeon supports 64 PCIe Gen 4 lanes from the CPU, while the Core i3 lists PCIe Gen 4 without a lane count. The Xeon’s eight-channel memory bus with 204.8 GB/s bandwidth is a major architectural advantage for memory-intensive server tasks, compared to the Core i3’s dual-channel configuration.

Specification Differences

The core and thread counts are the most obvious specification gap: 6 cores and 8 threads for the Core i3-1210U versus 28 cores and 56 threads for the Xeon Gold 6348. Clock speeds also differ, with the Core i3 having a 1,000 MHz base clock and 4.40 GHz boost, while the Xeon has a 2.60 GHz base and 3.50 GHz boost. The Xeon’s higher base clock suggests sustained performance, while the Core i3’s higher boost clock indicates short-burst capability.

Power consumption is a stark contrast. The Core i3-1210U has a TDP of 9 W, while the Xeon Gold 6348 has a TDP of 235 W. This is a 26x difference in thermal design power, making the Core i3 suitable for fanless or passively cooled designs and the Xeon requiring robust server cooling. Both processors have locked multipliers, so neither supports overclocking.

Memory support differs in both type and channel width. The Core i3 supports DDR4 and DDR5 in a dual-channel configuration, while the Xeon supports DDR4 only but in an eight-channel configuration with 204.8 GB/s bandwidth. ECC memory is supported only on the Xeon. The Core i3 includes integrated UHD Graphics 64EU, while the Xeon has no integrated graphics. The Xeon is marked for the Server/Workstation segment, while the Core i3 is for Mobile. The Xeon’s release date is 2021-04-05, while the Core i3’s is 2022-02-22.

Head-to-Head Benchmarks

The Xeon Gold 6348 wins all six head-to-head benchmarks, with every multi-core test showing a delta of -80.9% relative to the Core i3-1210U. In Cinebench R15 multi-core, the Xeon scores 4,441 versus 847 for the Core i3. The R20 multi-core test shows 18,507 for the Xeon and 3,533 for the Core i3. The R23 multi-core result is 44,066 for the Xeon versus 8,413 for the Core i3. These consistent -80.9% deltas indicate that the Xeon’s 28-core advantage translates directly into multi-threaded rendering performance.

Single-core benchmarks show a similar pattern, though with slightly different deltas. In Cinebench R15 single-core, the Xeon scores 626 versus 119 for the Core i3, a -81% delta. The R20 single-core test shows 2,612 for the Xeon versus 498 for the Core i3, again -80.9%. The R23 single-core test has the Xeon at 6,221 and the Core i3 at 1,187, maintaining the -80.9% delta. The Xeon’s single-core advantage is notable because the Core i3 has a higher boost clock, suggesting the Ice Lake-SP architecture is more efficient per clock than Alder Lake-U in this test suite.

The Core i3-1210U’s passmark scores, while not part of the head-to-head set, provide context for its standalone performance. It scores 10,228 in passmark multithread, 3,354 in single thread, and 102,965 in data compression. These numbers align with its 68th percentile ranking among all CPUs. The Xeon’s percentile is 67, making the two chips essentially tied in aggregate standing, despite the Xeon’s dominance in the head-to-head Cinebench tests. This suggests that the Core i3’s passmark results, particularly in data compression and integer math, are relatively strong for its core count.
