AMD Ryzen 5 7400 vs Intel Core 5 315 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between the AMD Ryzen 5 7400 and the Intel Core 5 315, with the AMD part winning six of the eleven shared tests and Intel taking five. The margins, however, are not evenly distributed. The AMD Ryzen 5 7400 dominates in throughput-heavy workloads, while the Intel Core 5 315 takes narrower wins in latency-sensitive or single-threaded tasks.

The largest single delta is in integer math. The AMD Ryzen 5 7400 scores 64,733 against the Intel Core 5 315's 31,690, a 104.3% advantage. That is more than double the Intel result. Data compression follows a similar pattern: the AMD part scores 261,749 versus 146,143, a 79.1% lead. Random string sorting shows the AMD chip ahead by 77.3% (31,110 vs. 17,551). Extended instructions favor AMD by 51.6% (19,924 vs. 13,143). Multithread performance gives the AMD Ryzen 5 7400 a 42.2% edge (21,712 vs. 15,272), and data encryption goes to AMD by 33.7% (14,865 vs. 11,119).

The Intel Core 5 315 wins the single-thread test decisively: 4,021 versus 3,248, a 19.2% margin. That result appears twice in the data (single_thread and singlethread), confirming the consistency. Prime number finding also favors Intel, with 112 versus 79, a 29.5% lead. Floating point math goes to Intel by a modest 3.9% (42,441 vs. 40,784). Physics is nearly a tie: Intel scores 1,163 versus AMD's 1,150, a 1.1% edge.

What the raw numbers indicate is that AMD's architecture delivers roughly 1.3 to 2.0 times the multi-threaded throughput of the Intel part in most integer-heavy tasks, while Intel's single-core design holds a clear advantage in lightly threaded scenarios. The physics result is essentially a wash, and the floating point difference is small enough to be within run-to-run variance. The overall benchmark averages reflect this: the AMD Ryzen 5 7400 posts an average score of 42,055, while the Intel Core 5 315 sits at 18,188. That places the AMD part in the 88th percentile of all CPUs in the database, versus the 72nd percentile for Intel.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 7400 uses the Zen 4 architecture, codenamed Raphael, built on a 5 nm process at TSMC. It is a desktop part in the 7000 series, socketed into AMD Socket AM5. The Intel Core 5 315 uses the Wildcat Lake codename, built on a 3 nm process at Intel's own foundry, and is a mobile part soldered to Intel BGA 1516.

Core counts are identical at six, but thread counts diverge: the AMD part supports 12 threads via SMT, while the Intel part has six threads with no simultaneous multithreading. That explains much of the multithread benchmark gap. Base clocks differ sharply as well: the AMD Ryzen 5 7400 runs at 3.30 GHz base and boosts to 4.30 GHz, while the Intel Core 5 315 starts at a low 1.50 GHz base and boosts to 4.40 GHz. The higher boost on Intel helps its single-thread wins, but the low base clock and missing SMT hurt its sustained multi-thread performance.

Cache hierarchies are structured differently. The AMD part allocates 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part shows 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The AMD chip has roughly 2.7 times the L3 capacity, which benefits workloads with large working sets. The Intel part has a smaller cache footprint but pairs it with a newer 3 nm process, which likely contributes to its higher single-thread clock ceiling.

Memory support also diverges. The AMD Ryzen 5 7400 supports DDR5 over a dual-channel bus with 83.2 GB/s of bandwidth and includes ECC support. The Intel Core 5 315 supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s of bandwidth and no ECC. The AMD part offers 39.5% more memory bandwidth, which matters for data-heavy workloads. PCIe connectivity differs too: AMD provides Gen 5 with 24 lanes from the CPU, while Intel provides Gen 4 with only 6 lanes. Integrated graphics are present on both, with AMD listing Radeon Graphics and Intel listing Xe3 Graphics with 2 Xe cores.

The AMD multiplier is unlocked; the Intel multiplier is locked. Production status is active for both. The Intel part carries a launch MSRP of $340. The AMD part has no launch MSRP recorded.

Where Each One Wins

The AMD Ryzen 5 7400 is the stronger choice for any workload that scales with threads, cache, or memory bandwidth. Data compression, integer math, random string sorting, extended instruction sets, encryption, and multithreaded rendering all favor AMD by substantial margins. The 16 MB of L3 cache and dual-channel 83.2 GB/s memory bandwidth give it an edge in database-style operations, large file processing, and virtualization scenarios. Its 65 W TDP and desktop socket also make it suitable for builds where sustained performance matters more than power efficiency.

The Intel Core 5 315 wins where single-thread responsiveness is the priority. Its 4,021 single-thread score and 4.40 GHz boost clock make it competitive in lightly threaded applications, and its prime number finding result (112 vs. 79) suggests strength in workloads that depend on rapid iterative calculations. The 15 W TDP and mobile BGA socket position it for thin-and-light laptops where battery life and low heat output are primary concerns. Its single-channel memory and 6 PCIe Gen 4 lanes limit expansion, but for everyday productivity tasks, the single-thread advantage may be more noticeable than the multi-thread deficit.

Physics performance is effectively tied, so neither part has a meaningful edge there. Floating point math is within 4%, so compute-heavy scientific workloads that do not rely on integer paths will see similar results from both.

The Verdict

The database results point to two distinct use cases. For a desktop system where multi-threaded throughput, memory bandwidth, and cache capacity determine performance, the AMD Ryzen 5 7400 is the clear pick. It wins six of eleven head-to-head tests, and the wins are lopsided: 104.3% in integer math, 79.1% in data compression, 77.3% in random string sorting. Its 12 threads and dual-channel memory architecture deliver an average benchmark score of 42,055, placing it in the 88th percentile of all CPUs. The unlocked multiplier and active desktop socket add flexibility for builders who want to tune performance.

For a mobile system or a workload dominated by single-threaded tasks, the Intel Core 5 315 holds the advantage. It wins the single-thread test by 19.2% and prime number finding by 29.5%, with a higher boost clock of 4.40 GHz. Its 15 W TDP makes it the efficiency-oriented option, and the 3 nm process node from Intel is the more advanced lithography. The trade-off is severe: 6 threads instead of 12, single-channel memory at 59.7 GB/s instead of dual-channel at 83.2 GB/s, and an average benchmark score of 18,188, which is less than half of the AMD part's average. The Intel chip sits in the 72nd percentile, close to its nearest rivals: the AMD EPYC 9274F, Intel Core i7-9700, Intel Core i7-1365U, and AMD Ryzen 7 5700U all sit within 0.1% of its average score.

The verdict is straightforward. Choose the AMD Ryzen 5 7400 for desktop builds and multi-threaded workloads. Choose the Intel Core 5 315 for mobile platforms and single-thread-sensitive applications. The data does not support a third option: the performance gap in multi-threaded tests is too large to ignore, and the single-thread gap is too small to overcome the AMD part's overall lead.
