Architecture Differences

The two processors represent fundamentally different design philosophies and market positions. The Intel Core i3-10325 is a desktop part from Intel's 10th Gen Core series, built on the Comet Lake architecture (specifically Comet Lake-R). It uses a 14 nm process node from Intel's own foundry. The AMD Ryzen 5 4680U is a mobile processor from AMD's 4000 series, based on the Zen 2 architecture with the Renoir codename, and it is manufactured on a 7 nm process by TSMC. This node difference is significant for power efficiency and transistor density; the AMD chip packs 9,800 million transistors into a 156 mm² die.

The core configuration differs notably. The Intel part offers 4 cores and 8 threads, while the AMD part offers 6 cores and 12 threads. Both use a dual-channel memory bus, but the Intel chip supports DDR4 with a memory bandwidth of 42.7 GB/s, while the AMD chip supports LPDDR4 with 34.1 GB/s. Cache layouts are also distinct: both have 64 KB of L1 per core, but the Intel chip has 256 KB of L2 per core versus 512 KB on the AMD chip. Both share 8 MB of L3, though the structure and placement differ given the different core counts.

The integrated graphics differ as well. The Intel Core i3-10325 uses UHD Graphics 630, while the AMD Ryzen 5 4680U uses Radeon Graphics with 448 SP. The Intel chip supports PCIe Gen 3 with 16 lanes (CPU only), while the AMD chip supports PCIe Gen 3 without a lane count specified. The Intel part is a desktop component with a socket of Intel Socket 1200, while the AMD part is a mobile component on AMD Socket FP6. The Intel processor remains active in production, while the AMD processor is end-of-life. The Intel chip released on 2021-03-15, and the AMD chip followed on 2021-04-12.

Where Each One Wins

The benchmark data reveals a split depending on the workload and the rendering engine version. In Cinebench R15, the AMD Ryzen 5 4680U is the clear winner in both multi-core and single-core tests. It scores 1291 in multi-core versus 881 for the Intel chip, a 31.8% advantage. In single-core, it scores 170 versus 124, a 27.1% lead. This suggests that for older rendering workloads or those that scale with the specific characteristics of the Zen 2 architecture, the AMD part holds a substantial edge.

In Cinebench R23, the situation reverses. The Intel Core i3-10325 wins in multi-core with 8747 versus 7073, a 23.7% margin. It also wins in single-core with 1234 versus 1163, a 6.1% margin. This indicates that the newer Cinebench workload favors the Intel processor's higher clock speeds and architecture. The Intel chip has a base clock of 3.90 GHz and a boost clock of 4.70 GHz, whereas the AMD chip has a base clock of 2.20 GHz and a boost clock of 4.00 GHz. The higher sustained clocks on the Intel part appear to translate into better performance in the R23 test.

For use cases, the AMD Ryzen 5 4680U may be more suitable for legacy rendering tasks and workloads that align with its higher core count and older benchmark behavior. The Intel Core i3-10325 is better positioned for modern multi-threaded rendering in Cinebench R23, where it outperforms the AMD chip by a wide margin. The Intel part also carries a higher average benchmark score (2530 versus 2424), placing it slightly higher in the overall percentile ranking (49 versus 48).

Specification Differences

The two processors differ across several key specification fields. The core and thread counts are different: Intel has 4 cores and 8 threads, while AMD has 6 cores and 12 threads. Clock speeds differ substantially: the Intel chip has a base clock of 3.90 GHz and a boost clock of 4.70 GHz, while the AMD chip has a base clock of 2.20 GHz and a boost clock of 4.00 GHz. The TDP is dramatically different: 65 for the Intel desktop part versus 15 for the AMD mobile part.

The process node and foundry differ: Intel uses 14 nm at Intel, while AMD uses 7 nm at TSMC. The AMD chip has a transistor count of 9,800 million and a die size of 156 mm², while the Intel chip does not have these figures recorded. Cache configuration differs in L2 size per core: 256 KB per core on Intel versus 512 KB per core on AMD. Both have 64 KB of L1 per core and 8 MB of shared L3.

Memory support differs: Intel supports DDR4 with a memory bandwidth of 42.7 GB/s, while AMD supports LPDDR4 with 34.1 GB/s. Both use a dual-channel memory bus, and neither supports ECC memory. The PCIe support is Gen 3 on both, but Intel specifies 16 lanes (CPU only), while AMD does not specify a lane count. The integrated graphics differ: Intel uses UHD Graphics 630, AMD uses Radeon Graphics 448SP. Sockets differ: Intel Socket 1200 versus AMD Socket FP6. The market segments differ: Desktop for Intel, Mobile for AMD. Release dates are close: 2021-03-15 for Intel and 2021-04-12 for AMD. The Intel part has a launch MSRP of $154, while the AMD part has no recorded launch MSRP. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The head-to-head benchmark data shows a clear split between the two Cinebench versions. In Cinebench R15 multi-core, the AMD Ryzen 5 4680U wins with a score of 1291 against the Intel Core i3-10325's 881. The delta is -31.8%, meaning the Intel chip trails by 31.8%. This is a substantial margin, and it aligns with the AMD chip's higher core count and the behavior of the R15 workload.

In Cinebench R15 single-core, the AMD Ryzen 5 4680U again wins with 170 versus 124, a delta of -27.1%. This is notable because the Intel chip has a much higher boost clock of 4.70 GHz versus 4.00 GHz, yet the AMD part still takes the single-core lead in this test. The architecture-specific behavior of Zen 2 in the R15 engine appears to favor the AMD design.

In Cinebench R23 multi-core, the Intel Core i3-10325 wins decisively with 8747 versus 7073, a delta of 23.7%. This flips the R15 result, showing that the newer rendering engine responds differently to the two architectures. The Intel chip's higher clock speeds and Comet Lake design give it a strong advantage here.

In Cinebench R23 single-core, the Intel Core i3-10325 wins with 1234 versus 1163, a delta of 6.1%. This is a narrower margin than the multi-core win, but it still represents a clear victory for the Intel part. The boost clock of 4.70 GHz likely contributes to this result.

The overall win count is tied at 2 wins each. The Intel chip wins the two R23 tests, while the AMD chip wins the two R15 tests. The average benchmark scores reflect this split: the Intel chip averages 2530, while the AMD chip averages 2424. The percentile rankings are close as well, with the Intel chip at the 49th percentile and the AMD chip at the 48th percentile. The nearest rivals for the Intel chip include the Intel Xeon E-2244G with an average score of 2527 and a delta of 0.1%, the Intel Xeon E5-1650 v3 with 2545 and a delta of -0.6%, the Intel Xeon E-2144G with 2514 and a delta of 0.7%, and the Intel Xeon E5-2643 v3 with 2511 and a delta of 0.8%. For the AMD chip, the nearest rivals are the Intel Core i5-8500B with 2423 and a delta of 0%, the Intel Core i7-9850HE with 2421 and a delta of 0.1%, the AMD Ryzen 3 PRO 4450U with 2413 and a delta of 0.5%, and the Intel Xeon E5-2630L v3 with 2409 and a delta of 0.6%. These rival comparisons place both chips in a similar performance tier, with the Intel chip holding a slight overall edge in average score.
