Intel Celeron J4005

The Intel Celeron J4005 is a dual-core mobile processor from Intel's Gemini Lake family, built on the Goldmont Plus architecture and manufactured on a 14 nm process. It runs at a base clock of 2000 MHz with a boost of 2.70 GHz, draws a 10W TDP, and is mounted on the BGA 1090 socket, indicating a soldered, non-upgradeable design. Benchmark results place this chip at the 7th percentile of all CPUs in the database, with an average benchmark score of 452. That score ties it directly with several older desktop parts, making its performance class clear: entry-level, low-power, and firmly in the bottom tier of modern processors.

Benchmark Performance

The Cinebench results for the J4005 are consistently low across every version of the test. In Cinebench R15, the multi-core score is 132. In R20, the multi-core score rises to 552, while the single-core score is 77. In R23, the multi-core score is 1315 and the single-core score is 185. These numbers are all far below what any modern desktop CPU would produce, but they are internally consistent: the J4005's multi-core scores are roughly seven times its single-core scores, reflecting the presence of two physical cores with no hyper-threading.

The average benchmark score of 452 places the J4005 in a tight cluster of rivals. Its nearest competitor, the Intel Celeron G1610, also scores 452, with a delta of 0%. The Intel Xeon E5335 is 0.1% slower, the AMD A4 PRO-7350B is 0.1% faster, and the Intel Core i3-540 is 0.2% faster. These deltas are within rounding error, meaning the J4005 is effectively indistinguishable from these three older desktop chips in aggregate performance. The 7th percentile ranking reinforces this: 93% of all CPUs in the database outperform the J4005, so it sits near the very bottom of the performance distribution.

Power and Thermals

The J4005 has a TDP of just 10W, which classifies it as an ultra-low-power part. This is consistent with its mobile market segment and its BGA 1090 socket, which is designed for compact, fanless devices. The 14 nm process and 93 mm² die size contribute to this low power envelope. A 10W TDP means that cooling requirements are minimal; a simple passive heatsink or a small low-profile fan would be more than adequate. The chip is end-of-life, so no new designs are being produced, but its power characteristics make it suitable for always-on or battery-powered systems where heat dissipation is a primary concern. The integrated UHD Graphics 600 also adds to the thermal load, but at this TDP level, the entire package remains easy to manage.

Single-Thread vs Multi-Thread Behavior

The J4005 has 2 cores and 2 threads, so it cannot leverage simultaneous multi-threading. The single-thread scores are 77 in Cinebench R20 and 185 in R23. These are extremely low numbers, indicating that the chip will struggle with any workload that is not heavily parallelized. The multi-core scores are 552 in R20 and 1315 in R23, which are higher but still modest. The ratio between multi-core and single-core scores is roughly 7:1, which suggests that the dual-core design scales well when both cores are active, but the absolute performance ceiling is very low.

For real-world applications, this split means that the J4005 can handle light multi-threaded tasks such as basic document editing or web browsing, but it will be slow for anything that requires significant single-thread performance, such as modern JavaScript-heavy websites or complex spreadsheet calculations. The boost clock of 2.70 GHz may provide a small improvement in single-threaded bursts, but the base clock of 2000 MHz is more representative of sustained performance. Overall, the chip's behavior is typical of a low-end dual-core from the late 2010s: capable of simple tasks, but not suited for demanding software.

How It Compares

Intel Celeron G1610, The G1610 matches the J4005 exactly with an average score of 452 and a delta of 0%. Both chips are effectively equal in benchmark performance, despite the G1610 being an older desktop part. The J4005 offers lower power consumption and a more modern architecture, but the raw performance is identical.

Intel Xeon E5335, The Xeon E5335 is 0.1% slower than the J4005, with an average score of 452. This is a negligible difference. The Xeon is a much older server chip, but the J4005's low clock speed and dual-core design bring it down to the same level.

AMD A4 PRO-7350B, The A4 PRO-7350B is 0.1% faster than the J4005, scoring 451 versus 452. Again, this is within measurement noise. The two chips are effectively tied, showing that the J4005 performs on par with a mid-2010s AMD APU.

Intel Core i3-540, The Core i3-540 is 0.2% faster, with an average score of 451. This is the largest delta among the nearest rivals, but it is still a rounding error. The i3-540 is a dual-core with hyper-threading from 2010, yet the J4005's newer architecture cannot overcome its lower clock speed and lack of SMT.

Who Should Consider It

Given the J4005's 7th percentile ranking and low Cinebench scores, it is not suitable for gaming, video editing, 3D rendering, or any compute-intensive workload. The single-core score of 185 in R23 is far too low for modern games, and the multi-core score of 1315 is insufficient for parallel tasks like video encoding. However, for basic office productivity, word processing, spreadsheets, email, and web browsing, the chip can handle these tasks, albeit without much headroom. The integrated UHD Graphics 600 is capable of driving a display and decoding video, so it can serve as a media playback device or a thin client.

The 10W TDP makes the J4005 an excellent choice for fanless or passively cooled systems, such as small form-factor PCs, digital signage, or embedded controllers. Its dual-channel DDR4 memory support with 38.4 GB/s bandwidth is adequate for light multitasking. For users who need a low-cost, low-power system that performs simple tasks, the J4005 is a viable option, but anyone needing more than basic functionality should look elsewhere.

Platform and Compatibility

The J4005 is soldered to the motherboard via the Intel BGA 1090 socket, which means there is no upgrade path. The chip is not removable, so any future performance improvements would require a full motherboard replacement. It supports DDR4 memory in a dual-channel configuration, providing 38.4 GB/s of bandwidth. ECC memory is not supported. For expansion, the CPU provides PCIe Gen 2 with 6 lanes, which limits the number and speed of add-in cards. The integrated UHD Graphics 600 handles display output, and the chip has a locked multiplier, so overclocking is not possible.

The processor was released on December 10, 2017, and is now end-of-life. Its launch MSRP was $107. The part number is SR3S5. Because it is a mobile part, it is typically found in laptops or all-in-one systems, but its BGA socket also appears in some low-end mini PCs. The lack of an upgrade path and the limited PCIe lanes mean that this platform is best suited for fixed, lightweight use cases. The 14 nm process and 93 mm² die size are modest by modern standards, but they contribute to the chip's low power draw and thermal simplicity. Overall, the J4005 is a functional but constrained processor, and its platform reflects that positioning.
