AMD Ryzen 5 7500X3D vs Intel Core i3-14100 Comparison

AMD Ryzen 5 7500X3D vs Intel Core i3-14100

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread desktop processor on the AM5 platform, while the Intel Core i3-14100 is a 4-core, 8-thread part on Socket 1700. The recorded benchmark data shows a decisive overall performance gap: the AMD part wins 9 of the 11 head-to-head tests, with the Intel chip taking only the two single-thread PassMark results. The Ryzen 5 7500X3D holds an average benchmark score of 44,573 against 18,318 for the i3-14100, placing the AMD chip at the 89th percentile of all CPUs versus the 72nd percentile for Intel. This is not a close contest in raw throughput, but the Intel part does claim a meaningful edge in lightly threaded workloads.

Where Each One Wins

The Ryzen 5 7500X3D dominates every heavily threaded and compute-intensive workload in the head-to-head set. Its largest advantages come in integer math and physics simulations, two areas that scale directly with core count and cache capacity. The multithread PassMark score of 25,047 versus 15,095 confirms a 65.9% lead, which points to the AMD chip as the clear choice for compilation, rendering, scientific computing, and any task that saturates all available cores.

The Intel Core i3-14100 wins only the single-thread PassMark tests, scoring 3,759 against 3,494 for the AMD part, a 7% advantage. This makes the i3-14100 the better pick for legacy software, lightly threaded games, or applications with strict single-core dependencies. The 4.70 GHz boost clock exceeds the 4.50 GHz boost of the AMD chip, and the recorded data shows that this translates into a real, if modest, win in single-thread performance. For users who run mostly single-threaded tasks and rarely push all cores, the Intel part delivers the higher peak responsiveness.

Everything else falls to AMD. Data compression, encryption, extended instruction sets, prime number finding, floating-point math, random string sorting, and physics all show the Ryzen 5 7500X3D with a substantial margin. The prime number test is the most extreme: 221 versus 55, a 301.8% difference. Physics shows a 190.1% lead (2,779 versus 958). The pattern is consistent and clear: any workload that engages multiple cores or uses the large L3 cache will favor AMD.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen 5 7500X3D is in the prime number test. The AMD chip scores 221 operations, the Intel i3-14100 scores 55, yielding a 301.8% delta. This test is highly sensitive to integer execution and cache behavior, and the 96 MB shared L3 cache on the AMD part is the likely driver. The second-largest gap is in physics: 2,779 versus 958, a 190.1% lead. Physics workloads often involve complex floating-point and memory access patterns, both of which favor the AMD design.

PassMark integer math shows AMD ahead by 56.1% (70,774 versus 45,329). Random string sorting, a memory-latency-sensitive test, goes to AMD by 89.7% (32,999 versus 17,397). Data encryption shows a 78.7% lead (15,797 versus 8,838), and extended instructions are 72.4% ahead (20,455 versus 11,865). Data compression is 56% in favor of AMD (271,649 versus 174,115). Floating-point math is the closest of the AMD wins, at 23.6% (43,594 versus 35,266). Even this "small" margin is substantial, representing a workload where the AMD chip still clearly outperforms.

The two tests won by the Intel Core i3-14100 are both the single-thread PassMark measurement, scored at 3,759 versus 3,494. The delta is 7%, which is consistent across the duplicate entry. No other benchmark in the head-to-head set favors Intel. The multithread test, by contrast, shows a 65.9% win for AMD (25,047 versus 15,095), a gap that reflects the core and thread difference: 6 cores and 12 threads against 4 cores and 8 threads.

Specification Differences

The core and thread counts differ significantly. The AMD Ryzen 5 7500X3D offers 6 cores and 12 threads, while the Intel Core i3-14100 provides 4 cores and 8 threads. The AMD base clock is 4.00 GHz against 3.50 GHz for Intel, but the Intel boost clock is higher at 4.70 GHz versus 4.50 GHz. TDP ratings are close: 65 watts for AMD, 60 watts for Intel.

The memory support differs. The AMD chip uses DDR5 only, while the Intel part supports both DDR4 and DDR5. The AMD memory bandwidth is listed at 83.2 GB/s; no bandwidth figure is recorded for the Intel chip. Both use a dual-channel memory bus. PCIe lane counts differ: the AMD processor provides Gen 5 with 24 lanes (CPU only), while the Intel chip offers Gen 5 with 16 lanes (CPU only).

The integrated graphics are different. AMD includes Radeon Graphics, while Intel uses UHD Graphics 730. Sockets are not compatible: AMD uses Socket AM5, Intel uses Socket 1700. The launch MSRP for the AMD Ryzen 5 7500X3D is $269, and for the Intel Core i3-14100 it is $134. The AMD processor has a larger die at 71 mm², but the Intel die is 163 mm²; transistor counts are recorded only for AMD at 11,270 million. Both have locked multipliers.

Architecture Differences

The AMD Ryzen 5 7500X3D is built on a 5 nm process at TSMC, while the Intel Core i3-14100 uses Intel's 10 nm process. The AMD codename is Raphael, part of the Ryzen 5 Zen 4 generation. The Intel codename is Raptor Lake-R, part of the Core i3 Raptor Lake Refresh generation. These are different design families with no shared architecture.

Cache structures differ substantially. The AMD chip has 64 KB of L1 per core and 1 MB of L2 per core, with 96 MB of shared L3 cache. The Intel chip has 80 KB of L1 per core and 1.25 MB of L2 per core, with only 12 MB of shared L3 cache. The 96 MB L3 on the AMD part is eight times larger than the Intel L3, which explains the large margins in memory-sensitive workloads like data compression and prime number calculation.

The process node difference is notable: 5 nm versus 10 nm. The AMD part is manufactured by TSMC, the Intel part by Intel. The AMD die is smaller at 71 mm², despite holding over 11 billion transistors, while the Intel die is 163 mm² with no listed transistor count. The AMD chip uses the Raphael 3D V-Cache design, which is not present on the Intel part. The Intel chip supports both DDR4 and DDR5 memory, giving it broader platform compatibility, while AMD is DDR5-only.

The Verdict

The data supports a clear split by workload type. The AMD Ryzen 5 7500X3D is the stronger processor for anything multi-threaded or cache-heavy. Its 65.9% multithread lead, 301.8% prime number advantage, and 190.1% physics lead make it the obvious choice for rendering, simulation, encryption, compression, and heavy multitasking. The 96 MB L3 cache delivers outsized gains in data-heavy tasks, and the 89th percentile standing reflects its position among all CPUs.

The Intel Core i3-14100 is the pick when single-thread performance is the priority. Its 7% single-thread advantage is the only head-to-head win, but for applications that rely on one or two cores, that margin translates into faster response times. The lower TDP of 60 watts and support for both DDR4 and DDR5 make it a flexible, lower-power option for basic desktop use. Its 72nd percentile is respectable, and its nearest rivals in the database are all Intel parts within a 0.3% delta, indicating a consistent performance tier.

For a buyer who needs maximum multi-core throughput, the AMD Ryzen 5 7500X3D wins decisively. For a buyer who prioritizes single-thread speed and platform flexibility, the Intel Core i3-14100 holds the edge. The benchmark results do not show a middle ground; each processor wins in its respective domain.
