Intel Core i3-4350 vs Intel Pentium Gold G5620 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Pentium Gold G5620 wins every recorded Cinebench comparison against the Intel Core i3-4350. The database records five head-to-head test results, and the Pentium Gold takes all five. The most striking pattern is the consistency of the margin. Across multi-core and single-core workloads, the G5620 leads by approximately 15% in every instance.

In Cinebench R15 multi-core, the Core i3-4350 scores 309 while the Pentium Gold G5620 scores 364, a delta of 15.1% in favor of the newer chip. The R20 multi-core test shows a similar gap: 1291 for the i3-4350 versus 1517 for the G5620, a 14.9% advantage. The single-core results follow the same trajectory. In R20 single-core, the i3-4350 manages 182 points, while the G5620 reaches 214, again a 15% difference. The R23 suite confirms the pattern with multi-core scores of 3076 versus 3613 and single-core scores of 434 versus 510, both showing a 14.9% lead for the Pentium Gold.

The consistency of these deltas is notable. A 15% gap across every test, regardless of workload type, suggests a fundamental clock-speed advantage rather than an architecture-specific strength. The Core i3-4350 has a base clock of 3.60 GHz, while the Pentium Gold G5620 runs at 4.00 GHz. That 0.4 GHz difference, roughly an 11% raw clock advantage, translates into the larger 15% observed performance gap once other architectural improvements are factored in.

Neither processor has a boost clock recorded in the database, which means these scores reflect sustained base-clock operation. The fact that the Pentium Gold maintains its lead in single-core tests, where clock speed is the dominant factor, reinforces the interpretation that the G5620's higher frequency is the primary driver of its performance edge.

Architecture Differences

The two processors come from different architectural generations and use different manufacturing processes. The Core i3-4350 is built on the Haswell architecture using Intel's 22 nm process node, with a die size of 177 mm² and 1,400 million transistors. The Pentium Gold G5620 uses the newer Coffee Lake architecture on a 14 nm process, with a smaller die size of 126 mm². The database does not list a transistor count for the G5620, but the die size reduction alongside the process shrink indicates a denser, more modern implementation.

Both chips feature 2 cores and 4 threads, so the thread count is identical. Cache configurations also match: each has 64 KB of L1 per core, 256 KB of L2 per core, and 4 MB of shared L3. The equal cache hierarchy means the performance difference cannot be attributed to cache capacity. Instead, the architectural generation and clock speed separate the two.

Socket compatibility differs completely. The i3-4350 uses Intel Socket 1150, while the G5620 requires Intel Socket 1151. This is a hard incompatibility: systems built for one processor cannot accept the other without a motherboard change. Memory support also diverges. The i3-4350 uses DDR3 memory, while the G5620 uses DDR4 with a recorded memory bandwidth of 38.4 GB/s. The i3-4350's memory bandwidth is not listed, but the generational shift from DDR3 to DDR4 typically brings higher bandwidth potential.

The integrated graphics differ as well. The i3-4350 carries Intel HD 4600, while the G5620 features UHD Graphics 630. Both provide display output, but the newer UHD 630 represents a later graphics architecture. The G5620 also supports ECC memory, a feature not available on the i3-4350. This makes the Pentium Gold suitable for error-correcting memory configurations, which can matter in stability-sensitive workloads.

PCIe support is recorded as Gen 3 for both, with the G5620's listing noting 16 lanes for CPU-only usage. The i3-4350's PCIe lane count is not specified. The G5620 is marked as end-of-life in production status, while the i3-4350's status is not recorded. Release dates differ by nearly five years: the i3-4350 launched in 2014, and the G5620 launched in 2019.

The average benchmark scores place the two chips close together in the overall database. The i3-4350 has an average score of 1058, and the G5620 averages 1045, a difference of just 1.2%. Both sit at the 29th percentile among all CPUs. The nearest rivals for the i3-4350 include the AMD Ryzen 5 2500U with a matching 1058 score, the Intel Core i7-2760QM at 1057 (0.1% delta), the AMD FX-8320E at 1059 (0.1% delta in the other direction), and the Intel Pentium G4600 at 1056 (0.2% delta). The G5620's nearest rivals are the AMD PRO A10-9700 at 1045 (0% delta), the Intel Core i5-6350HQ at 1046 (0% delta), the AMD PRO A10-8770 at 1046 (0.1% delta in the other direction), and the AMD Athlon X4 950 at 1047 (0.2% delta in the other direction).

FAQ

Q: Which processor is faster in single-core workloads?

A: The Pentium Gold G5620 wins every recorded single-core test. It scores 214 in Cinebench R20 single-core versus 182 for the Core i3-4350, and 510 in R23 single-core versus 434, a 14.9% advantage in each case.

Q: Do both processors have the same number of cores and threads?

Q: Can these processors be used in the same motherboard?

A: No. The Core i3-4350 uses Intel Socket 1150, while the Pentium Gold G5620 uses Intel Socket 1151. They are physically and electrically incompatible.

Q: What memory types do they support?

A: The Core i3-4350 supports DDR3 memory, while the Pentium Gold G5620 supports DDR4 memory. The G5620 has a recorded memory bandwidth of 38.4 GB/s; the i3-4350's bandwidth is not listed in the database.

Q: Does the Pentium Gold G5620 support ECC memory?

A: Yes, the G5620 has ECC memory support enabled. The Core i3-4350 does not support ECC memory.

Q: How do their overall average benchmark scores compare?

A: The Core i3-4350 has an average benchmark score of 1058, and the Pentium Gold G5620 has 1045. Despite the G5620 winning every head-to-head test, the overall averages are nearly identical because the i3-4350's Cinebench R15 multi-core score of 309 versus the G5620's 364 does not fully offset the aggregate across all recorded tests.

The Verdict

The data supports a clear conclusion: the Pentium Gold G5620 is the faster processor in every measured workload. Its 15% lead across all five Cinebench tests is consistent and substantial. The higher 4.00 GHz base clock, combined with the newer Coffee Lake architecture, delivers a uniform performance advantage over the 3.60 GHz Haswell-based i3-4350.

However, the choice is not purely about performance. The socket difference is decisive for system builders. A Socket 1150 motherboard cannot accept the G5620, and a Socket 1151 board cannot accept the i3-4350. If a user already owns a Haswell-era platform with DDR3 memory, upgrading to the i3-4350 is the only option among these two without replacing the motherboard and memory. Conversely, a new build on Socket 1151 with DDR4 memory naturally points toward the G5620.

The G5620's ECC memory support adds a capability the i3-4350 lacks, which matters for users prioritizing data integrity. The i3-4350's larger die size (177 mm² versus 126 mm²) and older 22 nm process suggest higher manufacturing cost per chip, but the database does not record a launch MSRP for the i3-4350, while the G5620's launch MSRP is $93. Neither processor offers an unlocked multiplier, so overclocking headroom is not a differentiator.

For raw performance, the Pentium Gold G5620 is the clear winner. For platform continuity on older hardware, the Core i3-4350 remains a functional choice, but the benchmark data shows it trails the newer chip by roughly 15% in every test.

Where Each One Wins

Pentium Gold G5620 wins in all measured performance categories. The five recorded benchmarks, covering Cinebench R15, R20, and R23 in multi-core and single-core variants, all show the G5620 ahead by approximately 15%. Its higher base clock gives it an edge in single-threaded responsiveness, and the newer Coffee Lake architecture extends that lead to multi-threaded workloads even with identical core and thread counts. The G5620 also offers ECC memory support and DDR4 compatibility, which matter for users building systems with newer components or requiring error correction. Its smaller die size and newer process node suggest a more power-efficient design at the same 54 W TDP.

Core i3-4350 wins in platform continuity for older systems. The database does not record any benchmark where the i3-4350 outperforms the G5620, so its advantage is entirely situational. For users with an existing Socket 1150 motherboard and DDR3 memory, the i3-4350 is the only drop-in upgrade path between these two options. The older Haswell platform is well established, and the 22 nm process with 1,400 million transistors represents a mature design. Its average benchmark score of 1058 is actually slightly higher than the G5620's 1045, indicating that in the broader CPU landscape, the two chips perform at nearly the same overall level despite the G5620's head-to-head dominance.

Use-case split: Choose the Pentium Gold G5620 for new builds, for any workload where the 15% performance advantage matters, or for systems requiring ECC memory support. Choose the Core i3-4350 only when constrained to a Socket 1150 platform with DDR3 memory, where the alternative would require a full platform replacement. For all other scenarios, the recorded data favors the G5620.
