Intel Pentium Gold G5400T

The Intel Pentium Gold G5400T is an end-of-life desktop processor from Intel, built on the Coffee Lake architecture using a 14 nm process. It is a dual-core part with four threads, a base clock of 3.10 GHz, and no boost clock, targeting low-power systems with a 35 W TDP. Benchmark data places this chip at the 24th percentile of all CPUs, with an average benchmark score of 943, indicating it sits firmly in the entry-level segment.

Benchmark Performance

The G5400T’s average benchmark score of 943 places it in a tightly contested group of rivals, where the differences are negligible. The closest competitor is the AMD Athlon X4 860K, which matches the Pentium Gold exactly with a delta of 0%. Immediately behind are the Intel Core i7-2715QE and the Intel Xeon X5560, each scoring 942, representing a 0.1% deficit relative to the G5400T. On the other side, the AMD A8-7670K scores 944, which is 0.1% ahead of the Pentium Gold. These deltas are within the margin of measurement noise, meaning the G5400T delivers essentially identical aggregate performance to all four of these rivals.

Looking at specific multi-threaded workloads, the G5400T produces a Cinebench R15 multi-core score of 270 and a Cinebench R20 multi-core score of 1128. In the newer Cinebench R23 test, it achieves 2686 points in multi-core. These numbers illustrate a processor that can complete basic rendering tasks but will lag significantly behind any modern mid-range or high-end chip. The Geekbench multi-core score of 1331 corroborates this positioning, showing that the chip’s dual-core design limits its throughput in parallel workloads.

For single-threaded performance, the G5400T scores 159 in Cinebench R20 single-core, 379 in Cinebench R23 single-core, and 646 in Geekbench single-core. These figures are modest but not disastrous, reflecting the chip’s 3.10 GHz base clock. The percentile ranking of 24% across all CPUs means that roughly three-quarters of all tested processors outperform it on average, which is expected for a low-power, dual-core part. The data suggests that this processor is not designed to compete on raw performance but rather to provide adequate compute for basic tasks within a strict power envelope.

Single-Thread vs Multi-Thread Behavior

The ratio between single-thread and multi-thread scores reveals how the G5400T handles different types of workloads. In Cinebench R23, the multi-core score of 2686 is roughly 7.1 times the single-core score of 379. This scaling is higher than the ideal 2.0 times for a dual-core chip, which suggests that the multi-core test benefits from the additional threads in a way that does not perfectly translate to real-world performance. However, the more telling comparison is between the Cinebench R20 scores: 1128 multi-core versus 159 single-core, a ratio of about 7.1 as well. In Geekbench, the multi-core score of 1331 is 2.06 times the single-core score of 646, which is close to the theoretical maximum for two cores with four threads.

This behavior indicates that the G5400T’s multi-threaded performance is heavily dependent on the workload’s ability to utilize all four threads. In applications that scale well with thread count, such as video encoding or 3D rendering, the chip can nearly double its effective throughput. In contrast, lightly threaded applications like older games or office productivity tools will see performance closer to the single-core scores, which are relatively low. The lack of a boost clock means that the processor runs at a fixed 3.10 GHz at all times, so there is no transient performance spike for bursty single-threaded tasks. For everyday use, the single-thread performance is adequate for web browsing and document editing, but it will feel sluggish in demanding applications that rely heavily on a single core.

Power and Thermals

The G5400T is rated for a 35 W TDP, which classifies it as a low-power processor. This is a defining characteristic of this chip, as it allows for compact cooling solutions and quiet operation in small form factor systems. The 35 W TDP means that a simple, passive or low-profile air cooler is sufficient to keep the processor within its thermal limits during sustained loads. The 14 nm process node from Intel contributes to this efficiency, as does the dual-core design with a modest 3.10 GHz clock.

The processor’s thermal characteristics imply that it is well-suited for systems where heat dissipation is a concern, such as home theater PCs or compact office desktops. The integrated UHD Graphics 610 further reduces the need for a discrete GPU in basic systems, lowering overall system power draw. However, the low TDP also caps the maximum performance, as the chip cannot sustain high clock speeds without exceeding its power budget. The data shows no boost clock, so the processor is locked to its base frequency, which is a deliberate design choice to maintain the 35 W envelope. For users who prioritize low noise and low heat over raw performance, this TDP class is a clear advantage.

Who Should Consider It

Given its benchmark scores, the G5400T is appropriate for specific, low-demand use cases. For basic office work, which includes word processing, spreadsheet management, and web-based email, the single-core score of 646 in Geekbench is sufficient to handle these tasks without noticeable lag. The multi-threaded scores, such as 2686 in Cinebench R23, indicate that the chip can also manage light multitasking with several open applications simultaneously.

For gaming, the G5400T is not a suitable choice for modern titles. The single-thread performance is too low to maintain high frame rates in CPU-intensive games, and the integrated UHD Graphics 610 is not designed for gaming. The data shows that the chip’s performance is on par with the AMD Athlon X4 860K, which is a legacy part, and the 24th percentile ranking confirms it is far below the average gaming CPU. Gamers should look elsewhere.

For content creation, the G5400T can handle entry-level tasks such as photo editing in basic software or encoding short videos, but the long render times implied by the Cinebench scores will frustrate users who work with large files or complex projects. The Cinebench R20 multi-core score of 1128 is roughly one-tenth of what a high-end desktop processor would achieve, so any serious rendering work is out of the question. The processor is best suited for a secondary office machine, a lightweight home server, or a media playback device where its low power draw is a benefit and its performance limitations are acceptable.

Platform and Compatibility

The G5400T is built for the Intel Socket 1151 platform, specifically for the Coffee Lake generation of processors. It is a desktop market segment part with a production status of end-of-life, having been released in April 2018. The processor supports dual-channel DDR4 memory with a peak bandwidth of 38.4 GB/s, and it also supports ECC memory, which is a notable feature for a low-cost chip. This makes it suitable for small home servers or workstations that require data integrity.

In terms of expansion, the G5400T provides PCIe Gen 3 with 16 lanes from the CPU. This allows for a single discrete graphics card or multiple lower-bandwidth devices, though the chip’s performance level means that pairing it with a high-end GPU would create a significant bottleneck. The integrated UHD Graphics 610 provides basic display output, so a dedicated GPU is not strictly required for office or media tasks. The processor is not multiplier unlocked, so overclocking is not supported, and its end-of-life status means that no new motherboards are being produced for it, though used and existing 1151 boards with Coffee Lake support will work.

The upgrade path for the G5400T is limited by its platform. Socket 1151 with Coffee Lake support includes higher-end processors such as Core i5 and Core i7 models from the same generation, which would offer substantially better performance while keeping the same motherboard and memory. However, the 24th percentile ranking of the G5400T means that any upgrade to a higher-tier Coffee Lake chip would provide a significant improvement in both single-thread and multi-thread scores. The 14 nm process and 126 mm² die size are shared with other Coffee Lake parts, so compatibility is straightforward within the same chipset family. For users with an existing 1151 system, the G5400T can serve as a low-power, low-cost replacement, but its performance ceiling is firmly in the entry-level class.
