AMD Ryzen 3 3100U vs Intel Core i7-14650HX Comparison

Head-to-Head Benchmarks

The benchmark data presents a complete sweep for Intel. Across all 11 recorded PassMark tests, the Intel Core i7-14650HX wins every single contest. The closest margin appears in single-threaded workloads, where Intel scores 3,841 against AMD's 1,592, a delta of 58.6 percent. That is a substantial gap, but it is the narrowest one in the entire comparison.

The multi-core gap is far wider. In the PassMark multithread test, Intel scores 33,495 against AMD's 3,348, a delta of 90 percent. The floating-point math test shows a 93.1 percent delta, with Intel at 84,999 and AMD at 5,854. Integer math follows a similar pattern: Intel posts 116,661 against AMD's 8,873, a 92.4 percent delta. Data compression results show Intel at 398,418 versus AMD's 38,455, a 90.3 percent delta. In data encryption, Intel scores 22,917 versus AMD's 1,972, a 91.4 percent delta.

The pattern is consistent across every workload type. Extended instructions show Intel at 24,150 versus AMD's 2,116, a 91.2 percent delta. Prime number finding has Intel at 152 versus AMD's 18, an 88.2 percent delta. Physics simulation scores show Intel at 2,202 versus AMD's 232, an 89.5 percent delta. Random string sorting delivers Intel at 43,035 versus AMD's 4,666, an 89.2 percent delta.

The average benchmark score tells the same story. Intel's average sits at 41,576, while AMD's average is 6,247. Intel's percentile ranking among all CPUs is 88, compared to AMD's 62. The nearest rivals in the database also frame the difference. AMD's closest competitors, the Ryzen Threadripper 1950X at 6,231 and the EPYC 7272 at 6,186, sit within 1 percent of its score. Intel, by contrast, trades blows with the Core Ultra 7 265H at 41,621 (0.1 percent behind) and the Ryzen 9 5900X at 41,376 (0.5 percent ahead). These are different performance strata entirely.

Architecture Differences

The two processors come from different design eras. AMD's Ryzen 3 3100U uses the Picasso codename, built on the Zen+ architecture. It is a 12 nm part manufactured by GlobalFoundries, with a die size of 210 mm² and 4,940 million transistors. Intel's Core i7-14650HX uses Raptor Lake-HX, a refresh of the Raptor Lake architecture. It is built on Intel's 10 nm process with a 257 mm² die size.

Core counts differ sharply. AMD provides 2 cores and 2 threads. Intel provides 16 cores and 24 threads. That thread advantage comes from Intel's hybrid design, which combines performance and efficiency cores, though the database does not break down the core types. The clock speeds also diverge. AMD's base clock is 1.90 GHz with a boost of 3.20 GHz. Intel's base clock is 2.20 GHz with a boost of 5.20 GHz.

Cache hierarchies are built differently. AMD assigns 96 KB of L1 cache per core and 512 KB of L2 cache per core, with 4 MB of shared L3. Intel assigns 80 KB of L1 per core and 2 MB of L2 per core, with 30 MB of shared L3. The L3 difference alone is 30 MB versus 4 MB, which heavily influences multi-threaded workloads.

Memory support differs as well. AMD supports DDR4 only, with dual-channel memory and a measured bandwidth of 38.4 GB/s. Intel supports both DDR4 and DDR5, also dual-channel, with no bandwidth figure recorded in the database. ECC memory support is absent on AMD but present on Intel. PCIe generation differs: AMD uses Gen 3, while Intel uses Gen 5 with 16 lanes available to the CPU.

Integrated graphics differ. AMD uses Radeon Vega 8. Intel uses UHD Graphics 710. The database does not provide graphics benchmark scores, so any comparison there remains qualitative.

Power envelopes are not directly comparable. AMD has a 15 watt TDP. Intel has a 55 watt TDP. The socket types also differ: AMD Socket FP5 versus Intel BGA 1964. Intel's multiplier is unlocked; AMD's is not.

Where Each One Wins

The data shows no workload category where AMD takes the lead. Every recorded benchmark, from single-threaded integer math to multi-threaded compression, favors Intel. The closest contest is single-thread performance, where Intel leads by 58.6 percent. That still represents a decisive advantage, but it is the area where AMD's deficit is smallest.

For single-threaded tasks, the gap is meaningful but not prohibitive. Intel's 3,841 single-thread score against AMD's 1,592 suggests that Intel has a significant per-core performance advantage, likely due to higher clock speeds and a more modern architecture. AMD's 3.20 GHz boost clock cannot match Intel's 5.20 GHz boost.

For multi-threaded workloads, the difference is enormous. Intel's 16 cores and 24 threads overwhelm AMD's 2 cores and 2 threads. The multithread score of 33,495 versus 3,348 is a 90 percent delta. Any workload that scales across cores, such as video rendering, code compilation, or scientific simulation, will show a massive Intel advantage. The floating-point math score of 84,999 versus 5,854 reinforces this, as does the integer math score of 116,661 versus 8,873.

The memory subsystem differences also favor Intel. The 30 MB L3 cache versus 4 MB provides a substantial buffer for frequently accessed data. Intel's support for DDR5, paired with its dual-channel bus, offers more memory bandwidth potential, though the database does not record a measured bandwidth figure for Intel.

AMD's only potential advantages are qualitative. Its 15 watt TDP suggests lower power draw, though no thermal or power efficiency benchmarks are recorded. Its integrated Radeon Vega 8 graphics may offer different performance characteristics than Intel's UHD Graphics 710, but no graphics scores exist in the database to confirm this.

The Verdict

The data is unambiguous. The Intel Core i7-14650HX outperforms the AMD Ryzen 3 3100U in every recorded benchmark. The average benchmark score of 41,576 versus 6,247 places these processors in completely different performance classes. Intel's 88th percentile ranking versus AMD's 62nd percentile confirms this separation.

For any workload that appears in the database, Intel is the correct choice. The single-thread advantage of 58.6 percent matters for everyday responsiveness and lightly threaded applications. The multi-thread advantage of 90 percent or more matters for heavily threaded tasks. The larger cache, faster memory support, and higher boost clock all reinforce Intel's position.

AMD's Ryzen 3 3100U, with its 2 cores and 15 watt TDP, appears designed for low-power mobile systems where efficiency matters more than peak performance. The database does not include efficiency benchmarks, so that claim cannot be tested here. What the data shows is that for pure compute performance, Intel wins every category.

The nearest rival data confirms Intel's standing. Its closest competitors in the database, the Core Ultra 7 265H and the Core 7 251TE, sit within 0.2 percent of its average score. These are similarly modern mobile processors. AMD's nearest rivals, the Threadripper 1950X and EPYC 7272, are desktop and server parts with far higher core counts. The 3100U's average score sits in that company, which suggests it competes with older high-core-count parts rather than modern mobile chips.

The verdict is straightforward. Intel Core i7-14650HX for any compute-intensive task. AMD Ryzen 3 3100U only if the 15 watt TDP and smaller physical footprint are the deciding factors, since the database records no performance advantage for AMD.
