Intel Celeron N5105 vs Intel Pentium Gold G5400T Comparison

Head-to-Head Benchmarks

The recorded data reveals a sharp split between these two processors. The Celeron N5105 dominates the Cinebench suite, while the Pentium Gold G5400T takes the Geekbench tests. This is not a close contest; it is a tale of two very different benchmark philosophies.

In the multi-core Cinebench tests, the Celeron N5105 is consistently ahead by roughly a quarter. In Cinebench R15 multi-core, the N5105 scores 341 against the G5400T's 272, a 25.4% advantage. The same margin appears in Cinebench R20 multi-core, with a 1422 to 1134 result, again a 25.4% gap. Cinebench R23 multi-core follows the pattern: 3388 versus 2700, a 25.5% lead. This consistency across generations of the test suggests a fundamental architectural strength for the N5105 in heavily threaded rendering workloads.

The single-core Cinebench results are even more decisive for the Celeron. In R20 single-core, the N5105 scores 200 against 160, a 25% win. In R23 single-core, it scores 478 versus 381, a 25.5% lead. These are not marginal victories; the N5105 is decisively faster in every Cinebench discipline, both single and multi-core.

The Pentium Gold G5400T fights back in Geekbench. In Geekbench multi-core, it scores 1331 versus 1189 for the N5105, a 10.7% lead. The single-core gap is even larger: 646 versus 516, a 20.1% advantage for the Pentium. This suggests the G5400T has a clear edge in workloads that Geekbench prioritizes, which often favor higher clock speeds and per-thread responsiveness.

The head-to-head record stands at five wins for the N5105 and two for the G5400T. That is a 5 to 2 split in favor of the Celeron. However, the Geekbench margin for the G5400T is substantial, particularly in single-core, which may matter for certain applications. The data shows two chips with complementary strengths, not a single universal winner.

Architecture Differences

The underlying designs could not be more different. The Celeron N5105 uses the Tremont architecture, part of the Jasper Lake family, built on a 10 nm process. The Pentium Gold G5400T is a Coffee Lake part, built on a 14 nm process. This process gap is likely a factor in the Celeron's lower power profile and its performance characteristics.

The core counts diverge significantly. The N5105 has 4 physical cores and 4 threads, while the G5400T has 2 cores and 4 threads. This extra core count gives the N5105 a natural advantage in multi-threaded workloads like Cinebench, where all cores can be utilized. The G5400T must rely on Hyper-Threading to reach 4 threads, which is less efficient than having 4 separate physical cores.

Clock speeds tell a different story. The G5400T has a base clock of 3.10 GHz and no boost clock listed. The N5105 has a base clock of 2.00 GHz but can boost up to 2.90 GHz. The G5400T runs at a higher sustained clock, which explains its Geekbench single-core win. The N5105's boost is limited, and its base clock is much lower.

Cache layouts also differ. Both have 64 KB of L1 cache per core and 4 MB of shared L3 cache. The key difference is L2: the N5105 has 1.5 MB shared across all cores, while the G5400T has 256 KB per core. This means a G5400T core has more private cache, which can improve per-thread performance.

Memory support is another separator. The N5105 supports DDR4 and LPDDR4 memory with a bandwidth of 46.9 GB/s. The G5400T only supports DDR4, with a bandwidth of 38.4 GB/s. The N5105 has a higher theoretical memory bandwidth, which helps in memory-intensive workloads.

The G5400T has a notable feature in ECC memory support, which the N5105 lacks. This is an important distinction for reliability-sensitive applications, though the N5105's higher bandwidth may compensate for workloads that need raw throughput.

Where Each One Wins

The N5105 is the clear winner in multi-threaded rendering and compute tasks. The Cinebench results show a consistent 25% lead across R15, R20, and R23 multi-core tests. This is directly attributable to its four physical cores versus the G5400T's two cores plus Hyper-Threading. Any workload that scales with core count will favor the N5105.

The N5105 also wins in single-core Cinebench tests, which is surprising given its lower clocks. The Tremont architecture appears to be more efficient per clock than the older Coffee Lake design. This makes the N5105 a strong choice for applications that are single-threaded but not clock-sensitive, such as some legacy software.

The G5400T wins in Geekbench, particularly in single-core. The 20.1% single-core lead suggests it excels at workloads that are very clock-sensitive and do not leverage the N5105's extra cores. Geekbench often emphasizes integer and floating-point operations that benefit from high clock speeds and low latency, which favors the G5400T's 3.10 GHz base clock.

The G5400T also has a Geekbench multi-core win, despite having fewer cores. This implies that its two fast cores with Hyper-Threading can outperform the N5105's four slower cores in certain multi-threaded scenarios. The 10.7% margin is not huge, but it is consistent.

For a user, the choice depends on the workload. The N5105 is better for rendering, video encoding, or any multi-core compute. The G5400T is better for applications that are clock-bound or require single-core responsiveness, such as older games or lightly threaded productivity apps.

The Verdict

The data indicates a clear split. For multi-core rendering and any workload that uses all cores, the Intel Celeron N5105 is the superior processor. Its 4 cores and 25.4% to 25.5% lead in every Cinebench multi-core test make it the obvious choice for video editing or 3D rendering. Its 10 W TDP also makes it far more efficient for mobile or compact systems.

For single-core responsiveness and Geekbench workloads, the Pentium Gold G5400T is the better pick. Its 20.1% single-core Geekbench win and 10.7% multi-core Geekbench win show a strength in applications that favor high clock speeds. That 3.10 GHz base clock is the key differentiator, especially for software that cannot use more than a couple of threads.

The G5400T also offers ECC memory support and 16 PCIe lanes, making it more suitable for a desktop workstation that needs reliability or expansion. The N5105 has a higher memory bandwidth, which could matter for memory-bound tasks.

The choice comes down to workload. The N5105 wins 5 out of 7 head-to-head benchmarks, but the G5400T's wins are in a different benchmark family. The Celeron N5105 for multi-core rendering, the Pentium Gold G5400T for single-core speed and desktop flexibility. The data does not support a single universal recommendation; it supports a use-case-based one.
