AMD EPYC 7702 vs Intel Core 3 100U Comparison

Head-to-Head Benchmarks

The recorded data presents a remarkably one-sided picture. In all six head-to-head Cinebench comparisons, the AMD EPYC 7702 takes the win, and by a consistently massive margin. The closest gap is in Cinebench R15 single-core, where the EPYC 7702 leads by 81.9%, and the largest single delta is also 81.9%, appearing across R15 multi-core, R20 multi-core, R20 single-core, and R23 multi-core. The Intel Core 3 100U never wins a single comparison in the head-to-head set, with a win count of zero against six for AMD.

The multi-core results are the most dramatic. In Cinebench R23 multi-core, the EPYC 7702 scores 58,539 against the Intel Core 3 100U's 10,624. That is a 5.5x advantage for the server chip. Cinebench R20 multi-core shows a similar relationship: 24,586 versus 4,462. The R15 multi-core test, the oldest workload in the set, still shows the EPYC 7702 at 5,900 against 1,070 for the Intel part. The pattern is consistent: the EPYC 7702 delivers roughly five and a half times the multi-threaded rendering performance in every generation of the Cinebench benchmark.

Single-core results are less lopsided but still favor AMD decisively. In Cinebench R23 single-core, the EPYC 7702 posts 8,264 against 1,499, a delta of 81.9%. The R20 single-core test shows 3,470 versus 629. The R15 single-core test shows 832 versus 150. Even in the workload most favorable to a low-power mobile chip, the AMD server processor leads by roughly the same 81.9% margin. The Intel Core 3 100U's boost clock of 4.70 GHz is higher than the EPYC 7702's 3.35 GHz boost, yet the older Zen 2 architecture still dominates single-threaded Cinebench scores.

The broader benchmark data reinforces this divide. The Intel Core 3 100U has a PassMark single-thread score of 3,506, while its average benchmark score across all recorded tests is 16,148. The EPYC 7702 has an average benchmark score of 16,932. Both processors sit at the 70th percentile among all CPUs in the database, which is a striking outcome given the difference in their target markets. The Intel part's nearest rivals by average score include the Intel Core i7-10850H (16,204, delta of -0.3%), the Intel Core i5-10600KF (16,228, -0.5%), the Intel Core i7-1260U (16,320, -1.1%), and the AMD Ryzen 5 4600H (16,341, -1.2%). The EPYC 7702's nearest rivals are the Intel Core i5-1240U (16,957, -0.1%), the AMD Ryzen 5 7235HS (16,902, 0.2%), the AMD EPYC 7742 (16,998, -0.4%), and the Intel Core i7-1260P (17,007, -0.4%). Despite the EPYC 7702's enormous core count, its average score sits only 4.9% above the Intel Core 3 100U, because the Intel chip has a much richer set of recorded PassMark tests that include integer math, floating point math, and encryption, while the EPYC 7702's benchmark record is limited to Cinebench runs.

The Verdict

The data indicates that the AMD EPYC 7702 is the clear performance winner in every recorded Cinebench workload. If the selection criterion is raw rendering throughput, the choice is unambiguous. The EPYC 7702 leads by 81.9% in every head-to-head test, and it delivers roughly 5.5x the multi-core score in Cinebench R23. There is no recorded test where the Intel Core 3 100U comes out ahead.

However, the two processors occupy entirely different market segments, and the data reflects that. The Intel Core 3 100U is a mobile part with a 15 W TDP, a 10 nm process node, and integrated UHD Graphics 64EU. The EPYC 7702 is a server/workstation processor with a 200 W TDP, a 7 nm process node, 64 cores, 128 threads, and no integrated graphics. The Intel chip's market segment is listed as Mobile, while the EPYC 7702 is listed as Server/Workstation. A user choosing between these two parts is not really comparing two products for the same job; they are choosing between a thin-and-light laptop processor and a rack-mounted server chip.

For users who need Cinebench multi-threaded performance, the EPYC 7702 is the only rational pick. The data shows a 5.5x advantage in R23 multi-core, and that gap is consistent across every Cinebench version. For users who need a mobile processor with integrated graphics, the Intel Core 3 100U is the only option in this pairing, since the EPYC 7702 has no iGPU at all. The Intel part also supports both DDR4 and DDR5 memory, while the EPYC 7702 is limited to DDR4.

Architecture Differences

The two processors are built on fundamentally different architectures. The Intel Core 3 100U uses Raptor Lake, specifically the Raptor Lake-U variant, on a 10 nm process node fabricated by Intel. The AMD EPYC 7702 uses Zen 2, codenamed Rome, on a 7 nm process node fabricated by TSMC. The EPYC 7702 is part of the EPYC 7002 series, while the Intel chip belongs to the Core 3 generation.

The core counts could hardly be more different. The Intel Core 3 100U has 6 cores and 8 threads. The EPYC 7702 has 64 cores and 128 threads. That is a 10.7x difference in cores and a 16x difference in threads, which explains the multi-core Cinebench results despite the EPYC's lower boost clock of 3.35 GHz versus 4.70 GHz.

Cache hierarchies also diverge sharply. The Intel part has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 10 MB of shared L3 cache. The EPYC 7702 has 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The EPYC 7702 also lists 3,800 million transistors on a 74 mm² die, while the Intel part's transistor count and die size are not recorded in the database.

Memory support is another major differentiator. The Intel Core 3 100U supports DDR4 and DDR5 in a dual-channel configuration, with no ECC support. The EPYC 7702 supports DDR4 only, but in an eight-channel configuration, with a recorded memory bandwidth of 204.8 GB/s and ECC support enabled. The Intel part's memory bandwidth is not recorded, but its dual-channel bus and lack of ECC position it clearly as a consumer mobile chip.

PCIe connectivity differs as well. The Intel Core 3 100U lists PCIe Gen 4 with 8 lanes (CPU only), while the EPYC 7702 lists PCIe Gen 4 without a lane count in the recorded data. The Intel chip has integrated UHD Graphics 64EU; the EPYC 7702 has no integrated graphics. The Intel part's socket is Intel BGA 1744, and the EPYC 7702 uses AMD Socket SP3.

Where Each One Wins

The AMD EPYC 7702 wins every recorded Cinebench head-to-head test. That includes all three generations of Cinebench (R15, R20, R23) in both single-core and multi-core variants. The delta is consistently 81.9% in favor of AMD. The EPYC 7702 also has a higher average benchmark score (16,932 versus 16,148) and a much larger cache pool: 256 MB of shared L3 versus 10 MB. Its eight-channel DDR4 memory with 204.8 GB/s of bandwidth and ECC support makes it suited for server and workstation workloads where memory capacity, reliability, and throughput matter more than power efficiency.

The Intel Core 3 100U wins in mobility and integration. It is a 15 W mobile part with integrated UHD Graphics 64EU, meaning a system built around it does not require a separate GPU for basic display. It supports both DDR4 and DDR5 memory, giving platform flexibility. It has a higher boost clock at 4.70 GHz and a smaller physical footprint by market segment, listed as Mobile rather than Server/Workstation. The Intel chip also has recorded PassMark scores that the EPYC 7702 lacks, including data compression at 136,497, data encryption at 8,128, extended instructions at 7,894, find prime numbers at 52, floating point math at 28,322, integer math at 39,580, multithread at 12,522, physics at 876, random string sorting at 15,191, and single-thread at 3,506. These PassMark results are not comparable to the EPYC 7702 because the EPYC 7702 has no recorded PassMark scores in the database, but they show that the Intel chip has been measured across a broader range of everyday workloads.
