AMD Ryzen 3 7320U vs Intel Xeon E5-2620 v3 Comparison

The Verdict

The benchmark data splits these two processors cleanly by workload, with the AMD Ryzen 3 7320U taking three of the four head-to-head wins and the Intel Xeon E5-2620 v3 taking one. The Ryzen 3 7320U is the clear choice for single-threaded and lightly threaded tasks, where its newer Zen 2 architecture and higher boost clock deliver commanding leads. The Xeon E5-2620 v3, with two additional cores and four additional threads, is the pick for heavily multithreaded rendering workloads where core count trumps per-core speed. Their average benchmark scores are nearly identical — 1916 for the AMD versus 1907 for the Intel — and both sit at the 43rd percentile among all CPUs, indicating they are direct peers in overall performance despite their vastly different designs. The Ryzen 3 7320U is a mobile part still in active production, while the Xeon E5-2620 v3 is an end-of-life server/workstation chip; the data suggests the AMD part is the more balanced choice for general use, while the Intel part remains relevant only for threaded workloads that scale beyond four cores.

Where Each One Wins

The AMD Ryzen 3 7320U wins decisively on single-core performance. In Cinebench R15 single-core, it scores 162.4 versus the Xeon’s 93, a 74.6% advantage. In Cinebench R23 single-core, it scores 1095 versus 931, a 17.6% lead. This pattern aligns with the boost clock difference: the Ryzen boosts to 4.10 GHz while the Xeon tops out at 3.20 GHz. For everyday responsiveness, lightly threaded applications, and any task that depends on a single fast core, the data points squarely to the AMD part.

The Intel Xeon E5-2620 v3 wins in one specific but important test: Cinebench R23 multi-core. It scores 6595 versus the Ryzen’s 4809, a 27.1% margin. This result reflects the Xeon’s six cores and twelve threads against the Ryzen’s four cores and eight threads. The Xeon also demonstrates strong multi-threaded capability in Cinebench R20, where it scores 2769, although no direct head-to-head R20 comparison is provided against the Ryzen. For sustained all-core rendering workloads, the Xeon is the better option. The Ryzen, however, wins the other multi-core test in the head-to-head set: Cinebench R15 multi-core, where it scores 790 versus 664, a 19% advantage. This suggests the Ryzen’s advantage is more pronounced in older or shorter rendering tasks, while the Xeon’s extra cores prevail in the newer, longer-running R23 workload.

Architecture Differences

The two processors come from fundamentally different eras and design philosophies. The AMD Ryzen 3 7320U is built on TSMC’s 6 nm process node with a die size of 100 mm², while the Intel Xeon E5-2620 v3 uses Intel’s 22 nm process with a die size of 356 mm² and 2,600 million transistors. The Ryzen uses the Zen 2 architecture (codename Mendocino), while the Xeon uses the older Haswell architecture (codename Haswell-EP). These process differences explain much of the performance-per-watt disparity, though specific wattage figures beyond TDP are not in the data.

The cache layouts differ significantly. The Ryzen has 64 KB of L1 and 512 KB of L2 per core, with 4 MB of shared L3. The Xeon also has 64 KB of L1 per core but only 256 KB of L2 per core, yet it features a much larger 15 MB of shared L3. The larger L3 cache on the Xeon is typical of server parts designed for larger working sets, while the Ryzen’s larger L2 per core supports its higher single-thread performance.

Memory support is another major differentiator. The Ryzen supports LPDDR5 memory on a dual-channel bus with 88.0 GB/s of bandwidth, while the Xeon supports DDR4 on a quad-channel bus with 59.7 GB/s of bandwidth. The Ryzen’s higher bandwidth is notable given its mobile positioning. The Xeon supports ECC memory; the Ryzen does not. PCIe connectivity also differs: the Ryzen offers Gen 3 with 4 lanes (CPU only), while the Xeon offers Gen 3 with 40 lanes (CPU only). The Xeon has no integrated graphics, whereas the Ryzen includes a Radeon 610M iGPU. The Ryzen uses the AMD Socket FT6; the Xeon uses Intel Socket 2011-3. The Ryzen is part of the 7000 series and was released in September 2022; the Xeon was released in September 2014. The Ryzen carries part number 100-000000676, and the Xeon carries SR207.

Head-to-Head Benchmarks

The head-to-head data provides four direct comparisons. The largest margin belongs to the AMD Ryzen 3 7320U in Cinebench R15 single-core, where it scores 162.4 against the Xeon’s 93. That is a 74.6% delta, an enormous gap that reflects the combined effect of the Ryzen’s much higher boost clock (4.10 GHz versus 3.20 GHz) and its modern Zen 2 core design. In Cinebench R23 single-core, the Ryzen again wins, scoring 1095 versus 931, a 17.6% advantage. The smaller margin in R23 suggests the Xeon’s Haswell architecture does relatively better in this newer test, but the Ryzen still holds a clear lead.

The Intel Xeon E5-2620 v3’s only win comes in Cinebench R23 multi-core, where it scores 6595 versus 4809, a 27.1% margin. This is the largest multi-core victory in the set and aligns with the Xeon’s 50% core advantage (6 versus 4) and 50% thread advantage (12 versus 8). The story is different in Cinebench R15 multi-core, where the Ryzen wins with 790 versus 664, a 19% margin. The reversal between R15 and R23 multi-core results is notable: in the older R15 test, the Ryzen’s per-core efficiency overcomes the Xeon’s core-count advantage, but in the newer, more demanding R23 test, the Xeon’s extra cores win out. Across all four head-to-head tests, the Ryzen wins three and the Xeon wins one.

Specification Differences

The two processors differ on nearly every specification line. The AMD Ryzen 3 7320U has 4 cores and 8 threads, while the Intel Xeon E5-2620 v3 has 6 cores and 12 threads.
