Q: Do both processors support the same memory type?

A: No. The Core i5-2400S supports DDR3 memory, while the Celeron N5105 supports DDR4 and LPDDR4 memory. Both use a dual-channel memory bus.

Architecture Differences

The two processors come from entirely different Intel design eras. The Core i5-2400S is a Sandy Bridge desktop part, fabricated on a 32 nm process with 1,160 million transistors. It uses a monolithic die of 216 mm². The Celeron N5105 belongs to the Jasper Lake family, built on Tremont architecture using a 10 nm node, with a much smaller die size of 63.8 mm².

Core and thread counts are identical: both parts feature 4 cores and 4 threads. The cache layouts, however, diverge significantly. The i5-2400S has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3 cache. The N5105 also has 64 KB of L1 per core, but its L2 is shared at 1.5 MB, and it has 4 MB of shared L3 cache. The i5-2400S enjoys a larger aggregate L2 and L3 pool.

Memory support differs as well. The i5-2400S only accepts DDR3 modules, whereas the N5105 supports DDR4 and LPDDR4. The N5105 also lists a memory bandwidth of 46.9 GB/s, a figure absent for the older chip. Both run dual-channel memory buses. The i5-2400S offers more PCIe lanes, with Gen 3, 16 lanes versus Gen 3, 8 lanes for the N5105.

Integrated graphics are also different. The i5-2400S carries Intel HD 2000, while the N5105 uses UHD Graphics 24EU. The i5-2400S is a desktop socketed part (Intel Socket 1155), whereas the N5105 is a mobile BGA 1338 package. Both are end-of-life products with locked multipliers. The i5-2400S released in January 2011, while the N5105 has no recorded release date in the database.

The Verdict

The benchmark data presents a split picture, and the choice depends entirely on workload type.

For multi-threaded rendering workloads, the Celeron N5105 is the clear winner. It leads by 23.2% in every Cinebench multi-core test recorded. The N5105 scores 341 vs 262 in Cinebench R15, 1422 vs 1092 in R20, and 3388 vs 2601 in R23. This consistent margin suggests a meaningful architectural advantage in sustained multi-core compute.

For single-threaded Cinebench performance, the N5105 also wins, though by a smaller margin. In R20 single-core, it scores 200 against the i5-2400S's 154, a 23% advantage. In R23 single-core, it scores 478 vs 367, again 23.2% ahead.

However, the Core i5-2400S dominates in Geekbench tests. It posts a 43.7% higher multicore score (1709 vs 1189) and a 14.9% higher singlecore score (593 vs 516). This indicates the i5-2400S has a significant edge in mixed integer/fp workloads as measured by Geekbench.

The overall average benchmark scores tell a narrow story: the i5-2400S averages 968, just 1.4% above the N5105's 955. The decision comes down to specific application use. Users running Geekbench-style workloads should pick the Core i5-2400S. Users prioritizing Cinebench rendering should pick the Celeron N5105.

The TDP difference is notable: 65 watts for the i5-2400S against 10 watts for the N5105. The N5105 offers substantially lower power draw. The i5-2400S also requires an older DDR3 platform, while the N5105 supports DDR4 memory, which may influence system-level decisions.

Head-to-Head Benchmarks

The head-to-head table shows a decisive split. The Celeron N5105 wins five of the seven recorded tests, while the Core i5-2400S wins two. The margins, however, tell different stories.

Cinebench multi-threaded: Celeron N5105 wins big. In Cinebench R15, the N5105 scores 341 against the i5-2400S's 262. That is a 23.2% advantage. The same margin appears in R20 (1422 vs 1092) and R23 (3388 vs 2601). The N5105 also leads by 23.2% in the R20 single-core test (200 vs 154) and the R23 single-core test (478 vs 367). These consistent margins indicate a uniform multi-thread and single-thread advantage in Cinebench workloads.

Geekbench: Core i5-2400S dominates. The i5-2400S posts a 43.7% higher Geekbench multicore score, with 1709 against 1189. In singlecore, the delta is 14.9%, with the i5-2400S scoring 593 versus 516. The i5-2400S's Geekbench wins are not just margins, they are the largest margins in either direction across all tests.

The data shows two distinct performance personalities. The N5105 excels in the Cinebench suite, where it wins every test by roughly a quarter. The i5-2400S excels in the Geekbench suite, where it wins by 14.9% to 43.7%. Notably, the i5-2400S's Geekbench multicore win is far larger than the N5105's Cinebench wins. The i5-2400S gains 520 points over the N5105 in Geekbench multicore, while the N5105 gains 79 to 787 points in its Cinebench wins.

The average benchmark scores reflect a near tie: 968 for the i5-2400S and 955 for the N5105. Both processors sit at similar percentile positions, 26th and 25th respectively. The data does not indicate a single superior processor; it indicates one that favors different workload types.

Given that the N5105 wins the majority of tests (5 out of 7), a reader might conclude it is generally faster. But the Geekbench results show the i5-2400S has a significant lead in that specific test family. The Celeron's Cinebench wins are consistent in percentage but smaller in absolute points when compared to the i5-2400S's Geekbench multicore win. The i5-2400S's 43.7% lead in Geekbench multicore is the largest margin in the entire head-to-head set.
