AMD Ryzen 3 7320U vs Intel Core i3-10300 Comparison

Head-to-Head Benchmarks

The recorded data shows a split result between these two processors, with each claiming victories in different benchmark generations. The AMD Ryzen 3 7320U wins three of the four head-to-head comparisons, but the Intel Core i3-10300 takes the most decisive victory in the modern multi-core test.

In Cinebench R15 multi-core, the AMD Ryzen 3 7320U scores 790 against the Intel Core i3-10300's 673, a 14.8% advantage for AMD. The single-core R15 result is even more lopsided: the Ryzen 3 7320U posts 162.4 versus 95 for the Intel part, a 41.5% lead. That single-core gap is the largest margin recorded in any test between these two chips, and it suggests a substantial per-thread performance advantage for the AMD architecture in that workload.

The Cinebench R23 results tell a different story. In multi-core, the Intel Core i3-10300 rebounds with a score of 6687 against 4809 for the Ryzen 3 7320U, a 39.1% advantage for Intel. This is the only test the Intel chip wins, but it wins it convincingly. The R23 single-core test returns to AMD's favor, with the Ryzen 3 7320U scoring 1095 against 944 for Intel, a 13.8% edge.

Looking at the broader benchmark averages, the two processors land nearly on top of each other. The Intel Core i3-10300 has an average benchmark score of 1934, while the AMD Ryzen 3 7320U averages 1916, a difference of less than 1%. Both sit at the 43rd percentile among all CPUs in the database. The nearest rivals for the Intel chip include the Intel Core i7-1180G7 (1930, 0.2% behind) and the Intel Core i7-7820HQ (1940, 0.3% ahead), placing it in a tightly packed performance band. The AMD chip's nearest rivals include the Intel Core i7-6700T (1918, 0.1% behind it) and the Intel Xeon E-2314 (1911, 0.3% behind), showing a similar clustering. The overall picture is one of near parity in aggregate performance, with workload-specific swings large enough to matter for particular use cases.

The Cinebench R20 results, available only for the Intel chip in the database, show scores of 2808 multi-core and 396 single-core. The Ryzen 3 7320U has Geekbench results in the database instead, scoring 3536 multi-core and 1103 single-core. These additional data points confirm the pattern: the AMD chip excels in single-threaded scenarios, while the Intel chip holds its own in multi-threaded rendering workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i3-10300 uses the Comet Lake architecture on a 14 nm process node, manufactured by Intel. It is a desktop part built for Intel Socket 1200. The AMD Ryzen 3 7320U uses the Zen 2 architecture on a 6 nm process node, manufactured by TSMC, and is a mobile part built for AMD Socket FT6. The process node difference is stark: 14 nm for Intel versus 6 nm for AMD, which explains much of the efficiency gap between them.

Both chips have 4 cores and 8 threads, so thread counts are identical. The cache configurations differ significantly. The Intel chip has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 8 MB of shared L3 cache. The AMD chip also has 64 KB of L1 per core but doubles the L2 to 512 KB per core, while its shared L3 is just 4 MB. The AMD part makes up for the smaller L3 with a larger L2 allocation per core.

Clock speeds favor Intel in the base clock comparison. The Intel Core i3-10300 runs at 3.70 GHz base and 4.40 GHz boost, while the AMD Ryzen 3 7320U runs at 2.40 GHz base and 4.10 GHz boost. The AMD chip boosts 0.30 GHz higher than the Intel chip's boost clock, but its base clock is 1.30 GHz lower. The TDP gap is the defining difference: 62 watts for Intel versus 62 watts for Intel is incorrect in the data, but the recorded TDP for Intel is 62 watts, and the AMD chip is rated at 15 watts. The AMD chip is a clear low-power mobile design.

Memory support also diverges. The Intel chip supports DDR4 memory on a dual-channel bus with 42.7 GB/s bandwidth. The AMD chip uses LPDDR5 on a dual-channel bus with 88.0 GB/s bandwidth, more than double the Intel chip's memory bandwidth. The AMD chip also ships with a 100 mm² die size, while the Intel chip's die size is not recorded in the database. PCIe support differs as well: the Intel chip provides Gen 3 with 16 lanes from the CPU, while the AMD chip provides Gen 3 with 4 lanes from the CPU. The integrated graphics differ too: Intel uses UHD Graphics 630, AMD uses Radeon 610M.

The release dates are separated by over two years. The Intel Core i3-10300 launched on April 29, 2020, while the AMD Ryzen 3 7320U launched on September 19, 2022. Both parts remain active in production status, and neither has an unlocked multiplier.

Where Each One Wins

The AMD Ryzen 3 7320U wins the single-core battles across every Cinebench test recorded in the head-to-head data. It posts a 41.5% lead in Cinebench R15 single-core, a 13.8% lead in Cinebench R23 single-core, and a 14.8% lead in Cinebench R15 multi-core. The Intel Core i3-10300 wins only the Cinebench R23 multi-core test, where its 39.1% advantage is the largest margin either chip holds in any test it wins.

For desktop users running multi-threaded rendering workloads, the Cinebench R23 multi-core result favors the Intel chip. The Intel chip's 6687 score places it well ahead of rivals like the Intel Core i7-1180G7 (1930 average score in the database) in the aggregate, and the 39.1% head-to-head margin over the AMD chip shows Intel's strengths in this specific benchmark generation.

For mobile users or anyone prioritizing single-threaded responsiveness, the AMD chip's R23 single-core score of 1095 against 944 for the Intel chip, combined with its 41.5% R15 single-core lead, makes it the clear choice. Its low 15-watt TDP and LPDDR5 memory support also position it for power-constrained environments.

The Geekbench results, recorded only for the AMD chip in the database, show a 3536 multi-core score and 1103 single-core score. These numbers indicate that the AMD chip's single-core performance extends beyond Cinebench into other benchmark suites, reinforcing its single-thread advantage.

Both chips share identical core and thread counts (4 cores, 8 threads), L1 cache configuration (64 KB per core each), dual-channel memory bus design, dual-channel memory bus support, and lack of ECC memory support. Both are locked and remain active in production status.

The Intel chip's 62-watt TDP versus the AMD chip's 15-watt TDP is one of the most consequential differences in the specification table, alongside the 0.30 GHz boost clock advantage for AMD and the 42.7 GB/s versus 88.0 GB/s is the memory bandwidth gap, and the 14 nm versus 6 nm process node difference.

The Verdict

The data supports a clear split: the AMD Ryzen 3 7320U is the better choice for single-threaded performance and power efficiency, while the Intel Core i3-10300 is the better choice for multi-threaded Cinebench R23 rendering scores. The AMD chip wins three of four head-to-head tests, including both single-core tests and the R15 multi-core test, but the Intel chip wins the R23 multi-core test by a 39.1% margin, the largest single win in either direction.

For users in power-constrained environments, the AMD chip's 15-watt TDP against the Intel chip's 62-watt TDP, combined with its LPDDR5 memory support and 6 nm process node, makes it the obvious pick. For users running multi-threaded rendering workloads in a desktop context, the Intel chip's 6687 R23 multi-core score and 8 MB of shared L3 cache provide a meaningful advantage despite its older architecture.

The near-identical average benchmark scores (1934 for Intel, 1916 for AMD) and matching 43rd percentile rankings among all CPUs indicate that these are closely matched processors overall. The choice comes down to workload: single-threaded and mobile users should favor the AMD Ryzen 3 7320U, while multi-threaded desktop rendering favors the Intel Core i3-10300.
