Q: Which processor supports faster PCIe?

A: The Intel Processor U300 supports PCIe Gen 4 with 8 lanes (CPU only), while the AMD Ryzen 3 7320U supports PCIe Gen 3 with 4 lanes (CPU only). This gives the Intel part a bandwidth advantage for attached devices.

Q: Do both processors support ECC memory?

A: No, neither processor supports ECC memory. Both are locked multipliers as well, so overclocking is not an option on either platform.

Where Each One Wins

The benchmark data splits the two processors into distinct roles. The AMD Ryzen 3 7320U takes the single multi-core win in the older Cinebench R15 test, scoring 790 against the Intel's 781, a margin of 1.1%. That is a narrow victory, but it shows the AMD part's 8 threads can keep pace in threaded workloads that are not heavily clock-dependent.

The Intel Processor U300 wins the other three head-to-head comparisons, and the single-core results are particularly lopsided. In Cinebench R15 single-core, the Intel scores 222 versus 162.4 for the AMD, a 36.7% advantage. In Cinebench R23 single-core, the gap grows to 47.6%, with Intel at 1616 and AMD at 1095. The Intel part also wins Cinebench R23 multi-core, scoring 4905 versus 4809, a 2% edge.

For workloads that depend on a single thread, such as older games, lightly threaded productivity apps, or general desktop responsiveness, the Intel Processor U300 is clearly the stronger choice. The data shows a massive single-thread performance lead that will be noticeable in everyday use. For heavily threaded rendering or encoding tasks, the two are nearly tied, with the AMD chip slightly ahead in the older R15 test and the Intel chip slightly ahead in the newer R23 test. The AMD Ryzen 3 7320U does have a Geekbench multi-core score of 3536 and a single-core score of 1103, but no comparable Geekbench data exists for the Intel part in this database, so a direct comparison on that test is not possible.

Architecture Differences

The Intel Processor U300 uses Raptor Lake architecture on a 10 nm process, built by Intel. It is part of the Raptor Lake-U family and carries the Intel Processor branding. The chip has 5 cores, which is an unusual configuration, and 6 threads, indicating a hybrid layout with fewer threads than cores would normally suggest. The cache hierarchy is generous: 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3 cache.

The AMD Ryzen 3 7320U uses Zen 2 architecture on a 6 nm process, built by TSMC. It belongs to the Mendocino codename family and the 7000 series. This is a more conventional 4-core, 8-thread design. The cache is smaller per core: 64 KB of L1, 512 KB of L2, and 4 MB of shared L3. The die size is listed at 100 mm², while the Intel part has no die size data recorded.

These architectural choices lead to different performance profiles. The Intel part's larger L3 cache and higher clock speeds (4.40 GHz boost) explain its dominant single-core results. The AMD part's smaller 6 nm process gives it a manufacturing advantage in terms of transistor density, but the recorded data shows that advantage does not translate into better single-thread performance. The Intel part also supports both DDR4 and DDR5 memory, while the AMD part is limited to LPDDR5. The AMD part does have a recorded memory bandwidth of 88.0 GB/s, a figure not available for the Intel chip.

Specification Differences

The two processors differ across nearly every specification field. The Intel Processor U300 has 5 cores and 6 threads, while the AMD Ryzen 3 7320U has 4 cores and 8 threads. Base clocks are 1.20 GHz for Intel and 2.40 GHz for AMD. Boost clocks are 4.40 GHz for Intel and 4.10 GHz for AMD. Both have a 15 W TDP.

The Intel part uses Intel BGA 1744 socket, the AMD part uses AMD Socket FT6. The process nodes are 10 nm (Intel) versus 6 nm (TSMC for AMD). The Intel part uses Raptor Lake architecture, the AMD part uses Zen 2. The Intel part has 8 MB of shared L3 cache, the AMD part has 4 MB. Memory support differs: DDR4 and DDR5 for Intel, LPDDR5 only for AMD. PCIe support differs: Gen 4 with 8 lanes for Intel, Gen 3 with 4 lanes for AMD.

The integrated graphics are UHD Graphics 48EU for Intel and Radeon 610M for AMD. The Intel part was released on 2023-01-03, the AMD part on 2022-09-19. The Intel part has a launch MSRP of $193, while no MSRP is recorded for the AMD part. Neither supports ECC memory, and both are locked multipliers. The Intel part number is SRMLU, the AMD part number is 100-000000676.

Head-to-Head Benchmarks

The largest single benchmark gap is in Cinebench R23 single-core, where the Intel Processor U300 scores 1616 against the AMD Ryzen 3 7320U's 1095. That is a 47.6% advantage, a massive difference that will be felt in any single-threaded application. The Intel part's boost clock of 4.40 GHz, combined with its larger cache, drives this result.

Cinebench R15 single-core shows a similar story, though the margin is slightly smaller. Intel scores 222, AMD scores 162.4, giving Intel a 36.7% lead. Again, the higher boost clock and architecture efficiency of the Raptor Lake design make the difference.

In multi-core workloads, the gap narrows considerably. Cinebench R23 multi-core has Intel at 4905 and AMD at 4809, a 2% win for Intel. The AMD part's 8 threads help it stay close, despite the Intel part's clock advantage. In Cinebench R15 multi-core, the AMD part actually wins, scoring 790 versus 781 for Intel, a 1.1% margin. This is the only test where the AMD chip comes out ahead, and the margin is small enough that it could be considered a statistical tie.

The average benchmark scores place the AMD part slightly higher overall: 1916 versus 1881 for Intel, a difference of about 1.9%. Both chips sit at the 43rd percentile among all CPUs. The nearest rivals for the Intel part are the Intel Xeon E3-1558L v5 (1882 avg, 0% delta), the Intel Xeon E3-1545M v5 (1879 avg, 0.1% delta), and the Intel Xeon E3-1270L v4 (1883 avg, -0.1% delta). The nearest rivals for the AMD part are the Intel Core i7-6700T (1918 avg, -0.1% delta), the Intel Xeon E-2314 (1911 avg, 0.3% delta), and the Intel Xeon E3-1575M v5 (1910 avg, 0.3% delta). These rival comparisons show both chips are solidly in the mid-range of mobile processors.

The Verdict

The choice between these two processors comes down to workload priorities. The Intel Processor U300 is the pick for anyone whose applications are heavily single-threaded. The data shows a 36.7% lead in Cinebench R15 single-core and a 47.6% lead in Cinebench R23 single-core over the AMD Ryzen 3 7320U. That is not a small difference; it is a generational gap in single-thread performance. The Intel part also wins multi-core in the newer Cinebench R23 test, though by a modest 2%.

The AMD Ryzen 3 7320U has its own merits. It wins the older Cinebench R15 multi-core test by 1.1%, and it has a slightly higher average benchmark score overall (1916 versus 1881). Its 8 threads and higher base clock of 2.40 GHz make it a capable choice for workloads that scale well with thread count. The AMD part also has a recorded memory bandwidth of 88.0 GB/s, which may benefit certain memory-intensive tasks.

For a general-purpose mobile processor, the Intel Processor U300 is the stronger recommendation. The single-core performance advantage is so large that it will dominate everyday tasks, and the multi-core results are competitive with the AMD part. The Intel chip also supports both DDR4 and DDR5 memory, giving system designers more flexibility. The AMD Ryzen 3 7320U is a reasonable alternative for users who prioritize multi-threaded performance in older benchmarks or who prefer the 6 nm process and the Radeon 610M graphics. But based strictly on the recorded benchmark data, the Intel Processor U300 wins 3 out of 4 head-to-head tests, and its single-core victories are by margins large enough to be decisive.
