Intel Core i5-14400 vs Qualcomm Snapdragon X2E-78-100 Comparison

Head-to-Head Benchmarks

The Intel Core i5-14400 has a substantial body of recorded benchmark data, while the Qualcomm Snapdragon X2E-78-100 has no benchmark scores in the database. This makes a direct score-for-score comparison impossible. The Intel part's average benchmark score is 32115, placing it in the 82nd percentile of all CPUs tracked. The Snapdragon X2E-78-100 sits at the 50th percentile with an average benchmark score of 0, meaning it has no recorded performance data to analyze.

The Intel Core i5-14400 delivers strong multi-threaded results across Cinebench tests. In Cinebench R23 multicore, it scores 21315 points. The Cinebench R20 multicore result is 8952, and the R15 multicore result is 2148. Single-core performance is also solid: Cinebench R23 single-core scores 3009, R20 single-core scores 1263, and R15 single-core scores 303. Geekbench results show 9807 in multicore and 1905 in single-core.

PassMark results for the Intel part show a wide range of workload-specific strengths. Integer math scores 82017, floating point math scores 61549, and extended instructions score 19816. Data compression scores 314995, while data encryption scores 16731. Random string sorting produces 32346, and finding prime numbers scores 80. The PassMark multithread score is 25080, with a single-thread score of 3741. Physics testing yields 1396.

The nearest rivals for the Intel Core i5-14400 provide context for its standing. The Intel Core i7-12800H has an average score of 32121, effectively identical with a delta of 0 percent. The Intel Core i7-13705H scores 32076, a 0.1 percent difference. The Intel Core i5-14450HX scores 32040, a 0.2 percent gap. The Intel Core i9-11900 scores 32226, putting it 0.3 percent ahead of the i5-14400. These tight deltas indicate the i5-14400 performs in a very narrow band around its direct competitors.

Because the Snapdragon X2E-78-100 has no benchmark entries, there are no wins to assign in either direction. The head-to-head benchmark data is empty, and the win counts for both parts are zero. The database records no performance measurements for the Qualcomm chip at this time.

Where Each One Wins

The Intel Core i5-14400 wins in every measurable performance category, solely because it has recorded data and the Snapdragon X2E-78-100 does not. The Intel part shows particular strength in multi-threaded workloads, as demonstrated by the Cinebench R23 multicore score of 21315 and the PassMark multithread score of 25080. These results indicate capable handling of heavily parallel tasks such as rendering and compilation.

Single-thread performance on the Intel side is also competitive. The Cinebench R23 single-core score of 3009 and the PassMark single-thread score of 3741 show strong responsiveness for lightly threaded applications. The Geekbench single-core result of 1905 reinforces this pattern.

The Snapdragon X2E-78-100 cannot claim wins in any category because the database contains no benchmark scores for it. Its percentile rating of 50 with an average score of 0 reflects the absence of data, not a measured performance level. The Qualcomm chip does have a higher core count at 12 cores versus 10, but without benchmark results, no performance advantage can be quantified.

Architecture Differences

The Intel Core i5-14400 uses the Raptor Lake architecture, specifically the Raptor Lake-R codename, built on a 10 nm process at Intel's foundry. It has 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The die size is 215 mm². Cache is organized as 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The chip supports DDR4 and DDR5 memory in a dual-channel configuration, and it supports ECC memory. PCIe connectivity is Gen 5 with 16 lanes from the CPU. Integrated graphics are UHD Graphics 730. The socket is Intel Socket 1700. The multiplier is locked. The part number is SRN3QSRN46, and the market segment is desktop. The release date is January 7, 2024, with a launch MSRP of $221.

The Qualcomm Snapdragon X2E-78-100 uses the Glymur codename under the Snapdragon X2 (Elite) generation. It is built on a 3 nm process at TSMC, a notably smaller node than Intel's 10 nm. The die size is 220 mm², slightly larger than the Intel part. It has 12 cores and 12 threads, with a base clock of 4.00 GHz and no listed boost clock. Cache organization differs significantly: 288 KB of L1 per core and 16 MB of shared L2, with no L3 cache listed. Memory support is LPDDR5X only, in a dual-channel configuration, with a memory bandwidth of 152.4 GB/s. ECC memory is not supported. PCIe connectivity is Gen 5 with 12 lanes from the CPU. Integrated graphics are Adreno X2-85. The socket is Qualcomm BGA 2343. The multiplier is locked. The part number is X2E78100, and the market segment is mobile. The release date is April 5, 2026.

The architectural split is clear. Intel uses a larger process node, a hybrid cache layout with per-core L2, and a shared L3 pool. Qualcomm uses a much smaller 3 nm node, a larger per-core L1, a shared L2 pool, and no L3. The Intel part supports both DDR4 and DDR5, while the Qualcomm part is limited to LPDDR5X. The Qualcomm chip has a higher base clock at 4.00 GHz versus 2.50 GHz, but no boost clock is recorded. The Intel chip has a higher lane count for PCIe at 16 lanes versus 12.

The two parts differ in nearly every fundamental specification. The Intel chip has more threads than cores, indicating hyper-threading, while the Qualcomm chip has equal core and thread counts. The Intel chip has a lower base clock but includes a boost clock, while the Qualcomm chip has a higher base clock and no recorded boost clock. The Intel chip lists a TDP of 65 W, while the Qualcomm chip has no TDP recorded. The cache hierarchies are structured differently, and the memory support is entirely distinct.

The Verdict

The recorded data presents a one-sided picture. The Intel Core i5-14400 has extensive benchmark results showing solid performance across Cinebench, Geekbench, and PassMark workloads. Its average benchmark score of 32115 places it in the 82nd percentile of all CPUs, and its nearest rivals are all within 0.3 percent of its score. The Snapdragon X2E-78-100 has no benchmark scores in the database, an average score of 0, and a 50th percentile rating that reflects missing data rather than measured performance.

For builders selecting a desktop processor, the Intel Core i5-14400 is the only option with verified performance data. It supports ECC memory, offers DDR4 and DDR5 compatibility, and provides 16 PCIe Gen 5 lanes. It is an active product with a launch MSRP of $221.

For mobile applications, the Snapdragon X2E-78-100 offers a newer process node at 3 nm, a higher core count at 12, a higher base clock at 4.00 GHz, and a higher memory bandwidth of 152.4 GB/s. However, none of these specifications have been validated by benchmark results. The absence of performance data means no conclusion can be drawn about its actual capabilities.

The verdict is straightforward. The Intel Core i5-14400 is the processor with measurable, competitive performance. The Snapdragon X2E-78-100 remains unproven in the database, with architectural promise but no recorded scores to support a performance claim. Buyers seeking a desktop CPU with confirmed results should choose the Intel part. The Qualcomm chip's mobile-focused design and future release date leave its performance profile entirely undetermined.
