Architecture Differences

The AMD Ryzen 5 7400 and the Intel Core 7 253PTE represent two distinct architectural approaches. The AMD chip is built on the Zen 4 architecture with the Raphael codename, fabricated on a 5 nm process at TSMC. The Intel chip uses the Bartlett Lake codename, manufactured on a 10 nm process at Intel's own foundry. These process differences are substantial, with the AMD part using a smaller transistor feature size.

The core configurations differ significantly. The AMD Ryzen 5 7400 uses 6 cores and 12 threads, while the Intel Core 7 253PTE uses 10 cores and 20 threads. This gives the Intel part a 66.7% advantage in thread count, which directly influences its performance in heavily threaded workloads. The AMD part's base clock is 3.30 GHz with a boost clock of 4.30 GHz, while the Intel part has a much lower base clock of 1.80 GHz but a substantially higher boost clock of 5.40 GHz.

Cache hierarchies also diverge. The AMD chip provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel chip provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Intel part has more than double the L3 cache, which can benefit workloads with large working sets.

Memory support differs as well. The AMD processor supports only DDR5 memory, while the Intel processor supports both DDR4 and DDR5 memory. Both use a dual-channel memory bus, but the Intel part has a slightly higher memory bandwidth rating at 89.6 GB/s compared to the AMD part's 83.2 GB/s.

The transistor counts and die sizes are only recorded for the AMD part: 6,570 million transistors on a 71 mm² die. The Intel part has no recorded transistor count or die size in the database.

The Verdict

The benchmark data favors the Intel Core 7 253PTE in most measured categories. Out of 11 head-to-head benchmark comparisons, the Intel processor wins 9, while the AMD processor wins 2. The Intel part's wins include the major performance categories: single-thread, multithread, integer math, floating point math, data compression, data encryption, prime number finding, and physics simulation.

The AMD Ryzen 5 7400 wins only in extended instructions and random string sorting. However, the AMD part holds a higher percentile ranking overall: it sits at the 88th percentile among all CPUs, while the Intel part sits at the 84th percentile. The AMD processor also has a higher average benchmark score of 42055 compared to the Intel's 34962, though this figure is influenced by the different benchmark suites each CPU was tested with.

The decision between these two depends on the specific workload. The Intel Core 7 253PTE is the stronger choice for compute-heavy tasks such as integer and floating point operations, where its lead is substantial. The AMD Ryzen 5 7400 is the better choice for workloads that rely on extended instruction sets and certain sorting algorithms, where it holds a clear advantage.

Where Each One Wins

The Intel Core 7 253PTE is the clear winner for compute-intensive workloads. Its 45.9% lead in integer math and 39.3% lead in floating point math make it the preferred choice for number-crunching applications such as scientific computing, data analysis, and financial modeling. The 13.3% multithread advantage, driven by its 10 cores and 20 threads, positions it well for rendering, video encoding, and other parallel workloads. The 14.4% single-thread lead also makes it the better option for lightly threaded applications that depend on peak clock speed.

The AMD Ryzen 5 7400 wins in extended instructions with a 16.5% margin, indicating an advantage in workloads that use specialized instruction sets such as cryptography or media codecs. Its 10.2% lead in random string sorting suggests it handles certain data processing and text manipulation tasks more efficiently. The AMD part also holds a higher percentile ranking at 88 versus Intel's 84, meaning it outperforms a larger fraction of all CPUs in the database on average.

For users prioritizing raw computational throughput, the Intel Core 7 253PTE is the stronger choice. For workloads that specifically rely on extended instruction sets or particular sorting algorithms, the AMD Ryzen 5 7400 delivers better results. The Intel part's lower TDP of 45 W versus the AMD's 65 W also indicates it may fit into more power-constrained systems, though thermal performance depends on the entire system configuration.
