Intel Celeron N5105 vs Intel Core i7-2715QE Comparison

The Verdict

The benchmark data presents a clear hierarchy between these two mobile processors, and it is not the one the model names suggest. The Intel Celeron N5105 wins all five head-to-head Cinebench comparisons, despite being positioned as the lower-tier product. The Core i7-2715QE, a Sandy Bridge part from 2011, holds a 25th percentile ranking among all CPUs, and the Celeron N5105 also sits at the 25th percentile, but the newer Jasper Lake chip achieves higher raw scores across every recorded test. The Celeron N5105 leads by roughly 19% in each multi-core and single-core Cinebench test, a consistent margin that suggests a fundamental architectural advantage rather than a workload-specific quirk. The data implies that anyone choosing between these two for a modern workload should favor the Celeron N5105, which delivers superior rendering performance in Cinebench R15, R20, and R23 while consuming far less power. The Core i7-2715QE retains its value only in scenarios where the older chip's specific platform features, such as its larger L3 cache or its Sandy Bridge architecture, are required, but the recorded benchmarks offer no category where it outperforms its rival.

Architecture Differences

The two processors come from different eras and design philosophies. The Core i7-2715QE uses the Sandy Bridge architecture, built on Intel's 32 nm process node, with a die size of 216 mm² and 1,160 million transistors. The Celeron N5105 uses the Tremont architecture, fabricated on Intel's 10 nm node, with a much smaller die size of 63.8 mm². The transistor count for the Celeron is not recorded in the database, but the die size difference alone indicates a significant density advantage for the newer part. Both chips have four physical cores, but the Core i7-2715QE supports eight threads through Hyper-Threading, while the Celeron N5105 has no multi-threading and runs four threads. The cache layouts differ notably: the Core i7-2715QE has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3, while the Celeron N5105 has 64 KB of L1 per core, 1.5 MB of shared L2, and 4 MB of shared L3. The L2 structure is a major divergence, with the older chip using per-core L2 and the newer chip pooling it across all cores. The Celeron N5105 also supports DDR4 and LPDDR4 memory with a recorded bandwidth of 46.9 GB/s, while the Core i7-2715QE's memory support is not listed in the database, though it does use a dual-channel memory bus. The integrated graphics differ as well: Intel HD 3000 on the Core i7-2715QE versus UHD Graphics 24EU on the Celeron N5105. The Celeron N5105 also exposes PCIe Gen 3 with 8 lanes (CPU only), while the Core i7-2715QE's PCIe configuration is not recorded. Both chips are end-of-life, use dual-channel memory, do not support ECC, and have locked multipliers.

Head-to-Head Benchmarks

The head-to-head results are uniformly in favor of the Celeron N5105, and the margins are remarkably consistent. In Cinebench R15 multi-core, the Celeron N5105 scores 341 against 275 for the Core i7-2715QE, a 19.4% lead. This is the largest percentage gap in the set. In Cinebench R20 multi-core, the Celeron scores 1422 versus 1149, a 19.2% advantage. The single-core R20 test shows the Celeron at 200 versus 162, a 19% lead. In Cinebench R23 multi-core, the Celeron scores 3388 versus 2737, again a 19.2% gap. The R23 single-core test shows 478 versus 386, another 19.2% gap. The Core i7-2715QE has no single-core R15 result in the head-to-head data, while the Celeron N5105 records 108.1 in that test. The average benchmark scores reflect the same pattern: the Celeron N5105 has an average of 955, while the Core i7-2715QE averages 942. The Core i7's nearest rivals include the Intel Core i3-8145U at 941 (0.1% delta), the AMD Athlon X4 860K at 943 (-0.1%), the AMD A8-7670K at 944 (-0.3%), and the Intel Core i3-1110G4 at 945 (-0.3%). The Celeron N5105's nearest rivals include the Intel Xeon W3570 at 955 (0% delta), the Intel Xeon W3550 at 956 (-0.1%), the AMD Athlon X4 870K at 956 (-0.1%), and the Intel Core i7-950 at 957 (-0.2%). The Celeron N5105 also has Geekbench results recorded, with a multi-core score of 1189 and a single-core score of 516; the Core i7-2715QE has no Geekbench data in the database. The Celeron wins all five head-to-head tests, giving it a 5-0 record, while the Core i7 has zero wins.

Where Each One Wins

The Celeron N5105 wins in every benchmark category where both processors have recorded data. It is faster in multi-core Cinebench R15, R20, and R23, and faster in single-core Cinebench R20 and R23. The consistent 19% margin across all tests suggests that the Tremont architecture's efficiency and the 10 nm process provide a broad performance uplift over Sandy Bridge, regardless of workload type. The Celeron also achieves this with a 10 watt TDP, making it the clear choice for thermally constrained environments. The Core i7-2715QE, by contrast, has no recorded benchmark wins. Its only potential advantages lie in its specifications: it has 8 threads versus 4, a larger 6 MB L3 cache versus 4 MB, and a higher boost clock of 3.00 GHz versus 2.90 GHz. However, none of these translate into a measured performance win in the database. The Core i7-2715QE's Sandy Bridge architecture is from an older era, and the data shows that raw thread count and cache size do not overcome the newer core design's efficiency. For users prioritizing rendering performance in Cinebench, the Celeron N5105 is the only choice supported by the measurements. For users who need the specific features of the Core i7-2715QE, such as its BGA 1023 socket or its larger L3 cache, the data does not show a performance justification, but those platform-level attributes may matter in legacy system contexts. The Geekbench data, available only for the Celeron, further reinforces its standing, with a multi-core score of 1189 and a single-core score of 516. The overall picture is unambiguous: the Celeron N5105 outperforms the Core i7-2715QE in every recorded metric while consuming significantly less power.
