AMD Ryzen 5 7500X3D vs Intel Core 5 221E Comparison

The AMD Ryzen 5 7500X3D and the Intel Core 5 221E occupy different corners of the desktop performance spectrum. The recorded data shows a clear split: the AMD chip wins in three of the eleven head-to-head benchmark comparisons, while the Intel chip takes eight. This division is not arbitrary. The AMD processor dominates in specialized instruction execution and physics simulations, while the Intel processor asserts its authority in raw throughput, mathematical workloads, and single-thread speed. The benchmark results suggest that the choice between these two depends entirely on the specific workload, with the AMD chip acting as a specialist and the Intel chip functioning as a generalist with high-volume output.

Where Each One Wins

The AMD Ryzen 5 7500X3D claims victory in extended instruction processing, prime number calculations, and physics workloads. The data shows a 12.3% lead in extended instructions, a 27.7% advantage in prime number finding, and a 24.6% edge in physics simulations. These wins point toward a processor that excels in tasks involving complex, branching logic and iterative calculations. The physics benchmark, which often relates to simulation and scientific computing, shows the AMD chip delivering a score of 2779 against the Intel chip's 2230. This indicates a specific strength in workloads that benefit from its unique cache architecture.

The Intel Core 5 221E wins in the remaining eight tests, covering the broad categories of data compression, encryption, floating-point math, integer math, multithreaded performance, random string sorting, and single-thread performance. The largest margin appears in floating-point math, where the Intel chip scores 79028 against the AMD chip's 43594, a 44.8% difference. This is a massive gap. The Intel processor also holds a 39.9% lead in integer math, scoring 117813 versus 70774. For multithreaded workloads, the Intel chip scores 30510 against 25047, a 17.9% advantage. The single-thread score also favors Intel, with 4147 against 3494, a 15.7% difference. These results indicate that the Intel processor is better suited for content creation, number crunching, and general productivity tasks that scale across many cores.

Architecture Differences

The architectural split between these two processors is fundamental. The AMD Ryzen 5 7500X3D uses the Raphael codename, built on a 5 nm process at TSMC. It features 6 cores and 12 threads. The Intel Core 5 221E uses the Bartlett Lake codename, built on a 10 nm process at Intel. It features 14 cores and 20 threads. This core count difference is substantial, with the Intel chip offering more than double the physical cores of the AMD chip.

The cache hierarchies tell a different story. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a massive 96 MB of shared L3 cache. The Intel chip has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and only 24 MB of shared L3 cache. The AMD chip's L3 cache is four times larger, which likely explains its strong showing in the physics and extended instruction benchmarks. The Intel chip compensates with higher per-core L1 and L2 caches and a significantly higher boost clock of 5.20 GHz compared to the AMD chip's 4.50 GHz.

The memory support differs as well. The AMD chip supports only DDR5 memory with dual-channel configuration and a bandwidth of 83.2 GB/s. The Intel chip supports both DDR4 and DDR5 memory, also dual-channel, with a higher bandwidth of 89.6 GB/s. Both support ECC memory. The PCIe lanes also differ: the AMD chip offers Gen 5 with 24 lanes, while the Intel chip offers Gen 5 with 16 lanes. The integrated graphics differ, with the AMD chip using Radeon Graphics and the Intel chip using UHD Graphics 730.

Head-to-Head Benchmarks

The data from the head-to-head comparisons provides a detailed look at where each processor excels. The Intel Core 5 221E's most dominant performance comes in floating-point math, where it scores 79028 against the AMD chip's 43594. This 44.8% advantage is the largest single margin in the entire comparison. Integer math shows a 39.9% lead for Intel, with scores of 117813 and 70774 respectively. These two benchmarks alone suggest that the Intel chip is far better equipped for scientific computing, financial modeling, and any workload that relies heavily on arithmetic operations.

The multithreaded benchmark shows the Intel chip scoring 30510 against the AMD chip's 25047, a 17.9% difference. This is less dramatic than the math benchmarks but still a clear victory. The Intel chip also wins in data compression with a 16.2% margin, scoring 324285 versus 271649, and in data encryption with a 17.7% margin, scoring 19205 versus 15797. Single-thread performance favors Intel by 15.7%, with scores of 4147 and 3494. Random string sorting shows a 12.4% advantage for Intel, with scores of 37686 and 32999.

The AMD Ryzen 5 7500X3D's wins are concentrated in specialized areas. The prime number benchmark shows a 27.7% advantage, with the AMD chip scoring 221 against the Intel chip's 173. Physics simulations show a 24.6% advantage, with scores of 2779 and 2230. Extended instructions show a 12.3% advantage, with scores of 20455 and 18216. These results indicate that the AMD chip's large L3 cache provides a significant benefit for workloads that have high data reuse or require frequent access to a large working set.
