AMD Ryzen 3 3100U vs Intel Core 7 150U Comparison

The Verdict

The data in this comparison is unambiguous. The Intel Core 7 150U wins every single head-to-head benchmark recorded in the database, taking 11 out of 11 comparisons against the AMD Ryzen 3 3100U. The average benchmark score tells the same story: the Intel part scores 17395, while the AMD part scores 6247. That places the Intel Core 7 150U in the 71st percentile of all CPUs, versus the 62nd percentile for the Ryzen 3 3100U.

The Ryzen 3 3100U is a 2-core, 2-thread mobile processor from AMD's 3000 series, built on the 12 nm Picasso design. The Intel Core 7 150U is a 10-core, 12-thread Raptor Lake-U processor on Intel's 10 nm node. These are not competing in the same performance class. The Ryzen 3 3100U belongs to a much older generation, while the Intel part is a modern mid-range mobile chip. For anyone choosing between these two for a laptop, the Intel Core 7 150U is the clear choice based on every measured metric in the database.

The only scenario where the Ryzen 3 3100U might be considered is if the system requires an AMD Socket FP5 platform, or if the integrated Radeon Vega 8 graphics are preferred over the Intel Iris Xe Graphics 96EU. But even in those cases, the performance gap is so wide that the Intel part should be the default pick unless compatibility forces the AMD option.

Architecture Differences

The two processors come from different architectural eras and different foundries. The AMD Ryzen 3 3100U uses the Picasso design, which is based on the Zen+ microarchitecture. It is manufactured on a 12 nm process at GlobalFoundries. The Intel Core 7 150U uses the Raptor Lake architecture, specifically the Raptor Lake-U variant, and is manufactured on Intel's 10 nm process at Intel's own fabs.

The transistor counts differ dramatically. The AMD part integrates 4,940 million transistors on a 210 mm² die. The Intel database entry does not list transistor count or die size. The cache structures also show a fundamental difference in design philosophy. The AMD processor provides 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Intel processor provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The Intel part's L3 cache is three times larger.

Memory support also differs. The AMD Ryzen 3 3100U supports DDR4 memory only, with a dual-channel bus and a recorded memory bandwidth of 38.4 GB/s. The Intel Core 7 150U supports both DDR4 and DDR5, also on a dual-channel bus, but the database does not record a bandwidth figure for it. PCIe connectivity is different as well: the AMD part uses PCIe Gen 3, while the Intel part uses PCIe Gen 4 with 8 lanes on the CPU.

The integrated graphics are another point of divergence. The AMD chip carries Radeon Vega 8 graphics, while the Intel chip carries Iris Xe Graphics with 96 execution units. Neither processor has ECC memory support, and neither has an unlocked multiplier. Both are classified as mobile parts and are listed as active in production.

Specification Differences

The two processors differ on nearly every specification field in the database. The core and thread counts are the most obvious gap: the Intel part has 10 cores and 12 threads, the AMD part has 2 cores and 2 threads. The boost clock is also significantly higher on the Intel part, at 5.40 GHz versus 3.20 GHz. The base clocks are nearly identical, with the AMD part slightly ahead at 1.90 GHz versus 1.80 GHz.

The process nodes differ: AMD uses 12 nm, Intel uses 10 nm. The foundries are different: GlobalFoundries for AMD, Intel for the Intel part. The transistor count is recorded only for AMD at 4,940 million, and the die size only for AMD at 210 mm². Cache sizes diverge sharply: the AMD L1 is 96 KB per core versus 80 KB per core for Intel; the AMD L2 is 512 KB per core versus 1.25 MB per core for Intel; the AMD L3 is 4 MB shared versus 12 MB shared for Intel.

Memory support differs as noted: AMD supports DDR4 only, Intel supports DDR4 and DDR5. Memory bandwidth is recorded only for AMD at 38.4 GB/s. PCIe generation differs: AMD uses Gen 3, Intel uses Gen 4 with 8 CPU lanes. Integrated graphics differ: Radeon Vega 8 on AMD, Iris Xe Graphics 96EU on Intel. The sockets are different: AMD Socket FP5 versus Intel BGA 1744. The release dates differ: the AMD part is dated late May 2026 in the database, while the Intel part is dated early January 2024. Neither has an unlocked multiplier, and neither supports ECC memory.

Head-to-Head Benchmarks

The database records 11 head-to-head benchmark comparisons, and the Intel Core 7 150U wins all 11. The margins are consistent and large. In single-threaded performance, the Intel part scores 3508 versus 1592 for the AMD part, a delta of -54.6 percent from the AMD perspective. That means the AMD processor is roughly 54.6 percent behind in single-thread work.

The gap widens substantially in multi-threaded tests. In the PassMark multithread test, the Intel part scores 14700 against 3348, a delta of -77.2 percent. The integer math test shows the Intel part at 51057 versus 8873, a delta of -82.6 percent. Floating point math follows the same pattern: 34405 for Intel versus 5854 for AMD, a delta of -83 percent. The data compression test shows 158622 for Intel versus 38455 for AMD, a delta of -75.8 percent.

The encryption test has the largest relative gap. Intel scores 10025 versus 1972 for AMD, a delta of -80.3 percent. Extended instructions show 8748 for Intel versus 2116 for AMD, a delta of -75.8 percent. The prime number test shows 58 for Intel versus 18 for AMD, a delta of -69 percent. Physics scores are 1012 for Intel versus 232 for AMD, a delta of -77.1 percent. Random string sorting shows 18269 for Intel versus 4666 for AMD, a delta of -74.5 percent.

The closest margin is in single-thread performance, where the Intel part is 54.6 percent ahead. The largest margin is in floating point math, where the Intel part is 83 percent ahead. In every category, the Intel Core 7 150U delivers more than double the AMD Ryzen 3 3100U's score, and in most categories it delivers roughly four to five times the score.

Where Each One Wins

Based on the recorded data, the Intel Core 7 150U wins every workload category in which both processors were tested. That includes data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithreaded tasks, physics simulations, random string sorting, and single-threaded tasks. There is no benchmark in the database where the AMD Ryzen 3 3100U takes a win.

The AMD Ryzen 3 3100U does have a slightly higher base clock at 1.90 GHz versus 1.80 GHz for the Intel part, which could matter in very specific power-limited scenarios, but no benchmark result reflects that advantage. The AMD part also uses a different socket and has Radeon Vega 8 graphics, which may be relevant for a system that specifically requires AMD Socket FP5 or AMD integrated graphics. However, from a pure performance standpoint, the database shows no workload where the AMD chip comes out ahead.

For use cases such as heavy multi-threaded rendering, data compression workloads, encryption tasks, or any sustained compute load, the Intel Core 7 150U is the only rational choice from this data. For light single-threaded tasks, the Intel part still leads by 54.6 percent. The AMD Ryzen 3 3100U would only be selected if platform compatibility forces the AMD socket, since the performance differential is overwhelming in the Intel chip's favor across every recorded metric.
