AMD Ryzen 5 7500X3D vs Intel Core 3 100UL Comparison

The Verdict

The data in the database presents a stark contrast between these two desktop processors. The AMD Ryzen 5 7500X3D is positioned in the 89th percentile of all CPUs tracked, with an average benchmark score of 44,573. The Intel Core 3 100UL sits at the 50th percentile with no recorded average score. The performance gap is so substantial that the Intel part cannot compete in computationally intensive tasks.

The Ryzen 5 7500X3D is the clear choice for any workload where processing power matters. Its benchmark results show a processor designed for heavy lifting, from data compression to floating-point mathematics. The Intel Core 3 100UL, with its 15-watt thermal envelope and low base clock, appears oriented toward energy-conscious builds where raw performance is secondary.

The Intel chip does have one distinct advantage: it is already active in the market since April 2024, while the AMD part arrived later in November 2025. For a system needing immediate deployment, the Intel processor is available today. The AMD chip supports ECC memory, while the Intel part does not, which could matter for specific reliability-focused applications.

The data suggests the AMD processor is the default recommendation for most desktop scenarios. The Intel Core 3 100UL makes sense only in low-power, basic computing contexts where its 15-watt TDP and integrated graphics are sufficient, and where the workload never approaches the demands that the AMD part handles with ease.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 7500X3D uses the Raphael codename, part of the Zen 4 generation, built on a 5 nm process at TSMC. It packs 11,270 million transistors into a 71 mm² die. The Intel Core 3 100UL uses Raptor Lake architecture with the Raptor Lake-PS codename, fabricated on Intel's 10 nm process. The database lists no transistor count or die size for the Intel part.

Cache configurations diverge sharply. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 per core, and a massive 96 MB of shared L3 cache. The Intel processor offers 80 KB of L1 per core, 1.25 MB of L2 per core, but only 10 MB of shared L3. The AMD part's 96 MB L3 is nine times larger, a defining architectural feature.

Memory support differs as well. The AMD processor uses DDR5 exclusively with dual-channel access and a measured memory bandwidth of 83.2 GB/s. The Intel chip supports both DDR4 and DDR5 in dual-channel mode, but the database records no bandwidth figure. ECC memory is supported on the AMD side, not on the Intel side.

PCIe connectivity shows another split. The AMD chip provides PCIe Gen 5 with 24 CPU lanes. The Intel processor offers PCIe Gen 4 with only 8 lanes. Integrated graphics are present on both: AMD includes Radeon Graphics, Intel includes UHD Graphics 64EU.

The core counts match at six, but threading differs. The AMD part runs 12 threads, while the Intel part runs 8. Base clocks tell a story of power priority: the AMD chip starts at 4.00 GHz, the Intel chip at just 1.20 GHz. Both boost to 4.50 GHz.

Specification Differences

The database records several fields where these two processors diverge. The AMD part belongs to the 7000 series, the Intel part has no listed series. The AMD chip uses AMD Socket AM5, the Intel chip uses Intel Socket 1700. Process nodes differ: 5 nm for AMD, 10 nm for Intel. The AMD foundry is TSMC, the Intel foundry is Intel itself.

Transistor counts are only listed for AMD at 11,270 million. Die size is listed only for AMD at 71 mm². L1 cache per core is 64 KB on AMD versus 80 KB on Intel. L2 cache per core is 1 MB on AMD versus 1.25 MB on Intel. L3 shared cache is 96 MB on AMD versus 10 MB on Intel.

Memory support lists DDR5 only for AMD, while Intel supports both DDR4 and DDR5. Memory bandwidth is recorded at 83.2 GB/s for AMD, with no figure for Intel. ECC memory is true for AMD, false for Intel. PCIe generation and lanes differ: Gen 5 with 24 lanes for AMD, Gen 4 with 8 lanes for Intel.

Integrated graphics differ: Radeon Graphics on AMD versus UHD Graphics 64EU on Intel. The AMD launch MSRP is recorded as $269, while the Intel part has no listed launch MSRP. Base clocks are 4.00 GHz for AMD and 1.20 GHz for Intel, though both boost to 4.50 GHz. TDP is 65 watts for AMD and 15 watts for Intel. Both have locked multipliers.

Head-to-Head Benchmarks

The database includes no direct head-to-head benchmark comparisons between these two processors, and the Intel Core 3 100UL has no individual benchmark scores recorded. The comparison must therefore rely on the AMD processor's measured results and its position relative to other CPUs in the database.

The AMD Ryzen 5 7500X3D delivers a multi-thread score of 25,047 on PassMark. Its single-thread score is 3,494. In integer math, it scores 70,774. Floating-point math reaches 43,594. Data compression scores 271,649. Data encryption scores 15,797. Extended instructions score 20,455. Prime number finding scores 221. Physics scores 2,779. Random string sorting scores 32,999.

The AMD chip's nearest rivals in the database provide context. The Intel Core Ultra X9 388H has an average score of 44,466, which is 0.2 percent behind the AMD part. The Intel Core i9-13950HX scores 44,342, a 0.5 percent deficit. The AMD Ryzen AI Max 385 scores 44,309, 0.6 percent behind. The Intel Core i5-14600 scores 44,889, which is 0.7 percent ahead of the Ryzen 5 7500X3D.

These rival comparisons show the AMD processor sits in a competitive band with high-end mobile and desktop parts. The Intel Core 3 100UL, with no recorded benchmarks and a 50th percentile standing, falls far outside this performance tier.

Where Each One Wins

The AMD Ryzen 5 7500X3D wins in every measured performance category recorded in the database. Its 6-core, 12-thread configuration combined with 96 MB of L3 cache produces benchmark scores that place it in the 89th percentile of all CPUs. The multi-thread score of 25,047 indicates strong parallel workload handling. The data compression score of 271,649 is particularly dominant, suggesting excellent memory subsystem performance.

The Intel Core 3 100UL wins in power efficiency. Its 15-watt TDP is less than a quarter of the AMD part's 65-watt rating. This makes the Intel processor suitable for systems where thermal output and energy consumption are primary constraints. Its support for both DDR4 and DDR5 memory provides flexibility in memory selection, allowing builders to reuse older DDR4 modules.

The Intel chip also wins on availability timeline, having launched in April 2024 compared to the AMD part's November 2025 release. The integrated UHD Graphics 64EU provides basic display output without a discrete GPU, similar to the AMD Radeon Graphics.

For computing tasks that stress the CPU, the AMD Ryzen 5 7500X3D is the only reasonable choice from this data. For lightweight, low-power desktop systems where the processor idles most of the time, the Intel Core 3 100UL offers a dramatically lower power draw. The 50th percentile standing of the Intel part indicates average performance relative to the database population, while the AMD part at the 89th percentile represents top-tier capability. The choice depends entirely on whether the workload demands performance or prioritizes power conservation.
