AMD Ryzen 5 7400 vs Qualcomm Snapdragon X2E-78-100 Comparison

The AMD Ryzen 5 7400 and Qualcomm Snapdragon X2E-78-100 represent two distinct approaches to modern computing, with the former built for high-performance desktop workloads and the latter designed for power-efficient mobile platforms. The database shows a stark contrast in their benchmark coverage: the Ryzen 5 7400 has a fully populated benchmark suite with an average score of 42055, while the Snapdragon X2E-78-100 currently has no recorded benchmark scores, leaving its performance profile undefined in our measurements. This disparity in data availability shapes the analysis, as the AMD processor’s strengths can be quantified against its rivals, whereas the Qualcomm chip’s capabilities must be assessed through its architectural specifications alone.

Where Each One Wins

The AMD Ryzen 5 7400 dominates the performance landscape based on recorded data. Its benchmark results show a processor that excels across a broad range of workloads, from data compression to floating-point math. The PassMark single-thread score of 3248 indicates strong per-core performance, which is critical for lightly threaded applications like web browsing, office productivity, and legacy software that relies on single-core speed. The multi-thread score of 21712 confirms that the 6-core, 12-thread configuration scales well under parallel workloads, making it suitable for content creation, compilation, and scientific computing. The floating-point math score of 40784 and integer math score of 64733 further reinforce its capability in numerically intensive tasks, while the extended instructions score of 19924 shows solid support for modern instruction set extensions.

The Qualcomm Snapdragon X2E-78-100 has no benchmark wins in the database because it has no recorded scores. However, its architectural profile suggests a different set of strengths. The 12-core design with 12 threads, a base clock of 4.00 GHz, and a 3 nm process node from TSMC points to a focus on multi-core throughput within a mobile power envelope. The LPDDR5X memory support with a bandwidth of 152.4 GB/s is significantly higher than the AMD chip’s 83.2 GB/s, which could benefit memory-bandwidth-sensitive workloads such as data analytics and certain AI inference tasks. The integrated Adreno X2-85 graphics and 12 PCIe Gen 5 lanes indicate a platform designed for thin-and-light laptops where GPU and CPU integration matters more than raw CPU grunt.

Architecture Differences

The two processors diverge fundamentally in their architectural foundations. The AMD Ryzen 5 7400 uses the Zen 4 architecture with the Raphael codename, built on a 5 nm process node from TSMC. It features 6 cores and 12 threads, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. The cache hierarchy is per-core: 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The transistor count stands at 6,570 million, packed into a die size of 71 mm². The processor uses the AMD Socket AM5 and supports dual-channel DDR5 memory with a bandwidth of 83.2 GB/s. It includes ECC memory support, which is a notable feature for workstation-class reliability. The integrated Radeon Graphics provide basic display output without needing a discrete GPU. The multiplier is unlocked, allowing overclocking for enthusiasts. The CPU is designated for the desktop market segment, with a production status of active.

The Qualcomm Snapdragon X2E-78-100 is a mobile processor with the Glymur codename, part of the Snapdragon X2 Elite generation. It uses a 3 nm process node from TSMC, which is a generation ahead of the AMD chip’s 5 nm node in terms of lithography. The die size is 220 mm², substantially larger than the AMD chip’s 71 mm², reflecting the integration of 12 cores and a different design philosophy. The cache configuration differs markedly: 288 KB of L1 per core, 16 MB of shared L2, and no L3 cache specified. The base clock is 4.00 GHz, but no boost clock is recorded. The processor uses the Qualcomm BGA 2343 socket and supports dual-channel LPDDR5X memory with a bandwidth of 152.4 GB/s, which is nearly double the AMD chip’s memory bandwidth. ECC memory is not supported. The integrated Adreno X2-85 graphics handle visual output. The multiplier is locked, preventing overclocking. The market segment is mobile, and the production status is active.

Head-to-Head Benchmarks

Direct head-to-head comparison is impossible because the database contains no benchmark results for the Qualcomm Snapdragon X2E-78-100. The headToHeadBenchmarks array is empty, and the winsA and winsB counters are both zero. This means the AMD Ryzen 5 7400 cannot be quantitatively compared to the Snapdragon X2E-78-100 in any specific test. Instead, the Ryzen 5 7400’s performance must be contextualized against its nearest rivals, which are all from the Intel and AMD ecosystems. The data shows the Ryzen 5 7400 sits at the 88th percentile among all CPUs, indicating it outperforms the vast majority of processors in the database.

Looking at the nearest rivals, the Ryzen 5 7400’s average benchmark score of 42055 places it in a tight cluster. It is 0.2% ahead of the AMD Ryzen 9 PRO 8945HS, which scores 41963. It is 0.3% ahead of the Intel Core i7-14700T, which scores 41914. It is 0.7% ahead of the Intel Core i7-12850HX, which scores 41779. However, it trails the Intel Core i9-12900K by 0.7%, as that chip scores 42335. These small deltas indicate that the Ryzen 5 7400 is competitively positioned against a range of high-end desktop and mobile processors, with the i9-12900K holding a slight edge in average performance.

In individual benchmark tests, the Ryzen 5 7400 shows specific strengths. The data compression score of 261749 is the highest recorded among its tests, indicating exceptional throughput in compression workloads. The random string sorting score of 31110 further demonstrates strong sorting and data manipulation capabilities. The find prime numbers score of 79 is relatively low, suggesting that this particular workload is not a strong point. The physics score of 1150 and data encryption score of 14865 are moderate, while the single-thread score of 3248 is solid for desktop applications. These numbers paint a picture of a balanced processor with particular excellence in data-centric tasks.
