Intel Core i5-13400E vs Intel Pentium Gold G6400 Comparison

The Intel Pentium Gold G6400 and the Intel Core i5-13400E occupy very different positions in Intel's desktop lineup, and the recorded data reflects that gap in every measured test. Both chips are active desktop parts, but the G6400 is a 2-core, 4-thread Comet Lake design while the 13400E is a 10-core, 16-thread Raptor Lake processor. The headline result is simple: across all five head-to-head benchmarks in the database, the Core i5-13400E wins every time, with the Pentium trailing by 86.8 percent in each test. That said, the two parts land in nearly the same overall percentile against the full CPU population, 63 for the G6400 and 62 for the 13400E, which makes this an interesting comparison to unpack rather than a one-sided rout on paper.

Head-to-Head Benchmarks

The database contains five direct comparisons, all from the Cinebench suite, and the pattern is remarkably consistent. In Cinebench R15 multi-core, the Pentium Gold G6400 scores 305 points against 2313 for the Core i5-13400E. In Cinebench R20 multi-core, the gap is 1272 versus 9639. Cinebench R20 single-core reads 179 for the G6400 and 1360 for the 13400E. Moving to Cinebench R23, the multi-core scores are 3030 against 22950, and single-core reads 427 against 3240. Every one of these tests records the same relative outcome: the 13400E finishes 86.8 percent ahead of the G6400.

That identical margin across single-core and multi-core tests is worth pausing on. Usually a many-core chip pulls far ahead in multi-threaded rendering while narrowing the gap in single-threaded work, because per-core throughput is closer between generations than total throughput. Here the recorded data shows the 13400E dominating both scenarios by the same proportion. The Raptor Lake part reaches a 4.60 GHz boost clock with modern cores, while the G6400 runs a fixed 4.00 GHz with no boost behavior recorded at all. Modern architecture plus higher clocks plus ten times the thread count produces a clean sweep.

Looking beyond the head-to-head suite, the G6400's broader benchmark record in the database fills out the picture. Its PassMark single-thread score sits at 2457, with integer math at 13941, floating point math at 8788, data compression at 62806, data encryption at 1535, extended instructions at 1784, random string sorting at 8034, physics at 356, and prime number finding at 17. The PassMark multithread result is 4118, which underscores the ceiling a 2-core, 4-thread design hits when work is parallelized. The 13400E has no PassMark entries recorded in the database, so the comparison rests on the Cinebench results, and those are decisive.

Context from each chip's nearest rivals adds useful framing. The G6400's average benchmark score of 6969 places it statistically alongside the Intel Xeon Platinum 8260 at 6992, the Intel Core i9-9960X at 6938, the AMD Ryzen 3 3200G at 6931, and the Intel Core i9-7980XE at 7018, all within one percent of each other. The 13400E's average of 6638 puts it near the AMD Ryzen Threadripper 2950X at 6647, the Intel Core i9-9940X at 6657, the Intel Core i9-12900E at 6611, and the Intel Pentium Gold G6405 at 6605. Those averages are close in absolute terms because they aggregate different test mixes, but the direct rendering comparisons leave no ambiguity about which processor is faster.

Architecture Differences

The generational divide here is wide. The Pentium Gold G6400 is built on Intel's 14 nm process using the Comet Lake architecture, launched on April 29, 2020, for Socket 1200. The Core i5-13400E uses the 10 nm node with the Raptor Lake-S codename, launched January 3, 2023, on Socket 1700. These are two different platforms entirely, so a swap between them means a new motherboard, and the sockets are not cross-compatible.

Core and cache counts diverge sharply. The G6400 pairs 2 cores with 4 threads, 64 KB of L1 cache per core, 256 KB of L2 per core, and 4 MB of shared L3. The 13400E brings 10 cores and 16 threads, 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 on a 215 mm² die. That is five times the raw cache at L3 and five times the cores, with Raptor Lake's hybrid thread scheduling making all 16 threads available to the operating system.

Platform features also differ in ways that matter for a build. The 13400E supports both DDR4 and DDR5 memory on a dual-channel bus, while the G6400 is DDR4 only, with a recorded memory bandwidth of 42.7 GB/s. The 13400E carries PCI Express Gen 5 with 16 CPU lanes, versus Gen 3 with 16 CPU lanes on the G6400, a difference that matters for fast storage and modern graphics cards. ECC memory support is present on the 13400E and absent on the G6400, which matters for stability-sensitive workstation duty. Integrated graphics differ too: UHD Graphics 730 on the i5 versus UHD Graphics 610 on the Pentium. Neither chip has an unlocked multiplier, so neither is an overclocking candidate. Power envelopes are close on paper, 58 W TDP for the G6400 and 65 W for the 13400E, but the 13400E delivers enormously more compute within that envelope thanks to the newer node and architecture.

The Verdict

The data points one direction for anyone doing real compute work. If rendering, content creation, compression, encryption, or any multi-threaded workload is on the agenda, the Core i5-13400E is the pick: it wins all five recorded head-to-head tests by 86.8 percent, offers 16 threads instead of 4, and doubles the memory standard support with DDR5 compatibility. Its Gen 5 PCIe, ECC support, and Socket 1700 platform also make it the more future-proof foundation.

The Pentium Gold G6400 still has a defensible niche, but a narrow one. Its 4.00 GHz base clock on two cores handles basic desktop tasks, web browsing, and light office work adequately, and its 63rd percentile placement against all recorded CPUs shows it is not bottom-of-the-barrel in the aggregate data. Its PassMark single-thread score of 2457 with a multithread score of 4118 tells you exactly what it is: quick for one or two threads, exhausted beyond that. Choose it only when the workload is genuinely light and the Socket 1200 platform already exists.

Specification Differences

The two processors differ in nearly every recorded specification. Cores: 2 for the G6400, 10 for the 13400E. Threads: 4 versus 16. Base clock: 4.00 GHz versus 2.40 GHz. Boost clock: none recorded for the G6400, 4.60 GHz for the 13400E. TDP: 58 W versus 65 W. Socket: Socket 1200 versus Socket 1700. Architecture: Comet Lake versus Raptor Lake, and process node: 14 nm versus 10 nm. Cache goes from 64 KB L1 per core, 256 KB L2 per core, and 4 MB shared L3 on the G6400 to 80 KB, 1.25 MB, and 20 MB respectively on the 13400E, which also records a 215 mm² die size. Memory support expands from DDR4 to DDR4 and DDR5, and ECC moves from unsupported to supported. PCIe steps from Gen 3 to Gen 5, both with 16 CPU lanes. Integrated graphics move from UHD Graphics 610 to UHD Graphics 730. Release dates are 2020 for the G6400 and 2023 for the 13400E. Both are active desktop parts from Intel with locked multipliers, so those traits do not differentiate them.

FAQ

Q: Does the Pentium Gold G6400 win any benchmark against the Core i5-13400E?

A: No. The database records five head-to-head tests, all from Cinebench, and the 13400E wins all five by 86.8 percent. The G6400 records zero head-to-head wins.

Q: How big is the single-core gap?

A: In Cinebench R23 single-core the scores are 427 for the G6400 and 3240 for the 13400E. In Cinebench R20 single-core it is 179 versus 1360. The margin is the same 86.8 percent recorded in the multi-core tests, so even lightly threaded work favors the i5 decisively.

Q: Which chip is newer, and are the sockets compatible?

A: The G6400 launched on April 29, 2020 on Socket 1200. The 13400E launched on January 3, 2023 on Socket 1700. The sockets are different, so the two chips cannot share a motherboard.

Q: Do both support DDR5 memory?

A: No. The G6400 supports DDR4 only, with a recorded bandwidth of 42.7 GB/s on a dual-channel bus. The 13400E supports both DDR4 and DDR5, also dual-channel.

Q: Which processor supports ECC memory?

A: Only the Core i5-13400E. ECC is recorded as supported on the 13400E and not supported on the G6400, a meaningful difference for workstation or server-adjacent builds.

Q: How do their overall database percentiles compare?

A: They are nearly identical: the G6400 sits in the 63rd percentile against all recorded CPUs and the 13400E in the 62nd. Those aggregate percentiles mask the direct performance gap, which the head-to-head Cinebench results expose clearly.

Where Each One Wins

The Core i5-13400E wins every measured contest against the G6400, so its use-case list is the longer one by far. Rendering in Cinebench R15, R20, and R23, whether single-core or multi-core, goes to the i5. Any workload that scales with threads, from code compilation-style parallelism implied by its 16-thread design to the encryption and compression tasks the G6400 struggles with at 1535 and 62806 respectively in its own PassMark record, favors the 13400E. Builds needing Gen 5 PCIe storage or graphics bandwidth, DDR5 memory, or ECC support have only one option here.

The Pentium Gold G6400 wins nothing in the recorded head-to-head data, but its role is defined by restraint rather than performance. Its higher 4.00 GHz base clock and modest 58 W TDP suit it to simple always-on boxes, basic office machines, and upgrades within an existing Socket 1200 platform. Its PassMark single-thread score of 2457 shows it can keep a light desktop responsive, and its percentile placement of 63 confirms competence at that tier. The practical summary: buy the 13400E for anything demanding, and accept the G6400 only when the workload is genuinely minimal and the platform cost of switching sockets is not justified by the performance need.
