AMD Ryzen 3 7320U vs Intel Xeon E3-1270L v4 Comparison

The AMD Ryzen 3 7320U and Intel Xeon E3-1270L v4 are both 4-core, 8-thread processors, but they target different worlds: one is a modern mobile chip built on a 6 nm process, the other a 2015-era server/workstation part on 14 nm. The recorded head-to-head data shows the AMD part winning three of four Cinebench comparisons, while the Intel part takes the most demanding multi-core test. Their average benchmark scores are nearly identical (1916 vs 1883), and both sit at the 43rd percentile among all CPUs, yet their strengths and intended use cases diverge sharply.

Where Each One Wins

The AMD Ryzen 3 7320U dominates single-core workloads. In Cinebench R15 single-core, it scores 162.4 against the Xeon's 92, a 76.5% lead. In Cinebench R23 single-core, it posts 1095 versus 919, a 19.2% advantage. The AMD chip also wins the older Cinebench R15 multi-core test, 790 to 656, a 20.4% margin. These results point to a clear pattern: the Ryzen 3 7320U is the stronger choice for lightly threaded tasks, everyday responsiveness, and any application that relies on a single fast core.

The Intel Xeon E3-1270L v4 wins only one head-to-head test, but it is a significant one. In Cinebench R23 multi-core, the Xeon scores 6512 against the Ryzen's 4809, meaning the AMD part is 26.2% behind. This is the most modern and demanding multi-threaded benchmark in the comparison, and the Xeon's victory suggests it holds an edge in sustained all-core rendering or compute workloads that scale well across all eight threads. The Xeon also has its own Cinebench R20 results (2735 multi-core, 385 single-core), though no direct comparison exists for that test.

Architecture Differences

The two chips are built on fundamentally different platforms. The AMD Ryzen 3 7320U uses the Zen 2 architecture (codename Mendocino) on a 6 nm TSMC process, with a die size of 100 mm². The Intel Xeon E3-1270L v4 uses the Broadwell architecture (Broadwell-DT) on Intel's 14 nm process, with a die size of 182 mm². The process node difference is stark: 6 nm versus 14 nm, which helps explain the Ryzen's much lower 15 W TDP compared to the Xeon's 45 W.

Cache layouts differ as well. Both have 64 KB of L1 per core, but the Ryzen has 512 KB of L2 per core versus the Xeon's 256 KB. The Xeon counters with a larger shared L3 cache: 6 MB versus 4 MB. Memory support is another major split. The Ryzen uses LPDDR5 in a dual-channel configuration with a memory bandwidth of 88.0 GB/s, while the Xeon uses DDR3 with dual-channel support and a bandwidth of only 29.9 GB/s. The Ryzen does not support ECC memory; the Xeon does.

PCIe connectivity also differs. The Ryzen offers Gen 3 with 4 lanes (CPU only), while the Xeon offers Gen 3 with 16 lanes. The Ryzen includes integrated Radeon 610M graphics; the Xeon has no integrated graphics. The Ryzen is a mobile part on AMD Socket FT6, while the Xeon is a server/workstation part on Intel Socket 1150. Their release dates are far apart: the Ryzen launched in September 2022, the Xeon in June 2015. The Ryzen is marked as active production, while the Xeon's production status is not specified.

The Verdict

The data points to a clear split. The AMD Ryzen 3 7320U is the better choice for single-threaded performance, lower power consumption (15 W versus 45 W), and modern memory bandwidth. It wins three of the four head-to-head benchmarks, including a massive 76.5% lead in Cinebench R15 single-core. It also brings integrated graphics, which the Xeon lacks, and a much smaller die size.

The Intel Xeon E3-1270L v4 is the better choice for heavily multi-threaded workloads that resemble Cinebench R23 multi-core, where it leads by 26.2%. It also offers ECC memory support and 16 PCIe lanes, making it more suitable for server or workstation environments that require error-correcting memory and more expansion capability. Its higher base clock (3.00 GHz versus 2.40 GHz) and larger L3 cache (6 MB versus 4 MB) may help in certain sustained workloads, though the benchmark data only shows the R23 multi-core win.

For a mobile or low-power system, the Ryzen 3 7320U is the obvious pick. For a server or workstation that prioritizes multi-threaded throughput and ECC, the Xeon E3-1270L v4 has a clear niche. The overall average scores are nearly identical, so the decision should rest on which workload pattern matters more.

Head-to-Head Benchmarks

The four recorded head-to-head comparisons reveal a consistent pattern. In Cinebench R15 multi-core, the AMD Ryzen 3 7320U scores 790 against the Xeon's 656, a 20.4% lead. This is an older benchmark, but it still shows the Ryzen's advantage in a multi-threaded test that is less demanding than R23.

The single-core R15 result is the most lopsided. The Ryzen posts 162.4, while the Xeon manages only 92, a 76.5% gap. This is a massive difference and underscores the Ryzen's architectural efficiency at low clock speeds. The Xeon's base clock is higher (3.00 GHz vs 2.40 GHz), but its boost clock is lower (3.60 GHz vs 4.10 GHz), and the Ryzen's Zen 2 cores clearly deliver more work per clock in this test.

In Cinebench R23 single-core, the Ryzen again wins, scoring 1095 versus 919, a 19.2% margin. The gap narrows compared to R15, but the Ryzen remains firmly ahead. The Xeon's R23 single-core score of 919 is still respectable, but it cannot match the Ryzen's modern core design.

The one reversal comes in Cinebench R23 multi-core. Here the Xeon scores 6512, while the Ryzen scores 4809, meaning the Ryzen is 26.2% behind. This is the only test where the Xeon wins, and it does so by a substantial margin. The Xeon's larger L3 cache (6 MB vs 4 MB) and higher base clock may contribute, but the benchmark result is what matters: for heavily threaded R23 workloads, the Xeon is the stronger part.

The Ryzen also has Geekbench scores (3536 multi-core, 1103 single-core) that are not directly compared, and the Xeon has Cinebench R20 scores (2735 multi-core, 385 single-core) that are not in the head-to-head set. These additional data points exist in the database but do not affect the head-to-head outcome.
