Intel Celeron G5920 vs Intel Pentium Silver J5005 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Pentium Silver J5005 wins every recorded Cinebench comparison against the Intel Celeron G5920. Across five head-to-head tests, the J5005 takes all five wins, with margins ranging from 17.9% to 18.6%. This is not a narrow edge; it is a consistent and substantial advantage in every workload the database tracks.

In the Cinebench R15 multicore test, the J5005 scores 268 against the G5920's 226, a delta of 18.6%. That is the largest single margin in the head-to-head set. The R20 multicore result tells a similar story: 1117 for the J5005 versus 945 for the G5920, an 18.2% gap. The R23 multicore test shows 2660 versus 2252, an 18.1% difference. In each multicore test, the J5005 holds roughly an 18% lead, which indicates a stable performance advantage rather than a workload-specific spike.

Single-core results follow the same pattern, though with slightly smaller margins. In Cinebench R20 single-core, the J5005 posts 157 against 133, an 18% delta. In R23 single-core, the J5005 scores 375 versus 318, a 17.9% gap. Even in the oldest test in the set, R15 single-core, the J5005 records 78.3, and while the G5920 lacks a published R15 single-core score in the head-to-head table, the overall pattern is consistent across all recorded comparisons.

The aggregate benchmark average reinforces this picture. The J5005 carries an average benchmark score of 776, while the G5920 sits at 775. That difference is tiny, only 0.1% in the nearest-rival comparison, but it is worth remembering the J5005 edges ahead even in the aggregate. The percentile ranking for both CPUs is identical at the 21st percentile of all CPUs, meaning neither chip is a high-flyer in the broader database, but relative to each other, the J5005 is clearly the stronger performer.

The nearest rivals for the J5005 include the AMD Athlon X4 760K at 777 (a 0.1% difference), the Intel Core i3-3250T at 775 (0.2% above the J5005), and the Intel Pentium G4520 at 778 (0.2% below). For the G5920, the nearest rivals are the Core i3-3250T at 775 (a 0% delta), the J5005 at 776 (0.1% above), and the AMD Athlon X4 760K at 777 (0.2% above). Both chips occupy the same performance tier in the aggregate database, but the J5005's consistent head-to-head wins make it the clear choice in direct comparison.

The Verdict

The data leads to a straightforward conclusion: the Intel Pentium Silver J5005 is the superior CPU in every benchmark the database records. It wins all five head-to-head tests against the Intel Celeron G5920, with margins between 17.9% and 18.6%. There is no recorded test where the G5920 closes the gap, let alone takes a win.

The J5005 should be the pick for anyone prioritizing raw Cinebench performance, whether single-core or multicore. Its scores are consistently higher across R15, R20, and R23 workloads. The G5920, by contrast, offers no benchmark-based reason for selection over the J5005 within the recorded data.

However, context matters. The J5005 is a mobile segment chip with a 10-watt TDP, while the G5920 is a desktop chip with a 58-watt TDP. The G5920 is an active production part, whereas the J5005 is end-of-life. If the use case requires an actively produced desktop processor, the G5920 has a practical advantage that benchmarks do not capture. But strictly from performance data, the J5005 wins without exception.

The aggregate scores are nearly identical, 776 versus 775, which might suggest parity. But the head-to-head results contradict that impression. The J5005's advantage is real and consistent in every direct comparison. The 21st percentile ranking for both CPUs indicates neither is a top-tier part, but within this pairing, the J5005 is definitively stronger.

Architecture Differences

The two processors come from different architectural families and target different market segments. The Intel Pentium Silver J5005 is built on the Goldmont Plus architecture, with the codename Gemini Lake. It is a mobile segment part, designed for low-power systems. The Intel Celeron G5920 uses the Comet Lake architecture, also with the codename Comet Lake, and is a desktop segment part.

Both chips are manufactured on Intel's 14 nm process node, so the underlying transistor geometry is the same. The foundry is Intel for both. The J5005 has a die size of 93 mm², while the G5920's die size is not recorded in the database.

The core configurations differ significantly. The J5005 has 4 cores and 4 threads, while the G5920 has 2 cores and 2 threads. This explains the J5005's multicore advantage: it has twice the core count, and the benchmark results show about an 18% lead in multicore workloads, not a doubling, which suggests the G5920's higher clock speed partially compensates for its lower core count.

Cache hierarchies also differ. The J5005 has 56 KB of L1 cache per core and 4 MB of shared L2 cache, with no L3 cache recorded. The G5920 has 64 KB of L1 per core, 256 KB of L2 per core, and 2 MB of shared L3 cache. The G5920's larger per-core L1 and per-core L2, plus its dedicated L3, are typical of a higher-clocked desktop part.

Integrated graphics differ as well. The J5005 includes UHD Graphics 605, while the G5920 includes UHD 610. Both are entry-level integrated solutions, but the database does not record graphics benchmarks, so no performance comparison is possible from this data.

PCIe support is another differentiator. The J5005 offers Gen 2 with 6 lanes (CPU only), while the G5920 offers Gen 3 with 16 lanes (CPU only). The G5920's newer PCIe generation and higher lane count are meaningful for desktop expansion, though no benchmarks in the database measure this.

Specification Differences

The specification table shows several fields where the two CPUs diverge. Clock speeds are a major difference. The J5005 has a base clock of 1500.00 MHz and a boost clock of 2.80 GHz. The G5920 has a base clock of 3.50 GHz and no boost clock recorded, meaning it runs at a fixed frequency. The G5920's base clock is more than double the J5005's base clock, yet the J5005 still wins in single-core benchmarks, which is a notable result.

Thermal design power differs substantially. The J5005 has a TDP of 10 watts, while the G5920 has a TDP of 58 watts. The J5005 is far more power-efficient on paper, though the database does not include power consumption measurements.

Socket types are incompatible. The J5005 uses Intel BGA 1090, a soldered mobile socket, while the G5920 uses Intel Socket 1200, a desktop socket. This means they cannot be swapped into the same motherboard.

Memory support shows both support DDR4 and dual-channel memory, but bandwidth differs: the J5005 records 38.4 GB/s, while the G5920 records 42.7 GB/s. The G5920 has a higher theoretical memory bandwidth.

Neither CPU supports ECC memory, and neither has an unlocked multiplier. The J5005 has a launch MSRP of $161, while the G5920 has no recorded launch MSRP in the database. Release dates differ: the J5005 was released on 2017-12-10, while the G5920 was released on 2020-04-29. Production status also differs: the J5005 is end-of-life, while the G5920 is active.

The J5005's part number is SR3S3, and the G5920's is SRH42.

Where Each One Wins

The Intel Pentium Silver J5005 wins in every recorded benchmark category. It takes the R15 multicore test with 268 against 226, an 18.6% margin. It wins R20 multicore with 1117 against 945, an 18.2% margin. It wins R23 multicore with 2660 against 2252, an 18.1% margin. In single-core tests, it wins R20 with 157 against 133, an 18% margin, and R23 with 375 against 318, a 17.9% margin.

The J5005 is the pick for any workload that the database measures. Its four cores provide a consistent edge in multicore rendering, and its single-core scores are also higher despite a much lower base clock. The J5005 is also far more power-efficient on paper, with a 10-watt TDP versus the G5920's 58-watt TDP, making it suitable for low-power mobile systems.

The Intel Celeron G5920 does not win any recorded benchmark. Its advantages are outside the performance data: it is an active production part, it uses a desktop socket with PCIe Gen 3 and 16 lanes, and it has a higher base clock of 3.50 GHz. It also has a higher memory bandwidth of 42.7 GB/s. For a builder who needs an actively produced desktop CPU with modern PCIe support, the G5920 has practical merits, but those are not reflected in Cinebench scores.

The database shows a clear split. For pure benchmark performance, the J5005 is the winner in all five head-to-head tests. For system-level features such as socket compatibility, PCIe generation, and production status, the G5920 holds advantages that the benchmarks do not measure. The choice depends on whether the priority is measured performance or platform characteristics.
