AMD Ryzen 3 PRO 4355GE vs Intel Xeon E5-4620 v3 Comparison

The AMD Ryzen 3 PRO 4355GE and the Intel Xeon E5-4620 v3 occupy nearly identical positions in the aggregate benchmark hierarchy, with the Ryzen posting an average score of 2596 and the Xeon scoring 2587. This places both at the 49th percentile of all CPUs, and their head-to-head deltas are consistently below one percent. Despite a decade of architectural divergence, a 15-core deficit, and a 70W TDP gap, these processors deliver statistically equivalent Cinebench results across every test. The data reveals a fascinating collision between a modern low-power APU and an aging high-core-count server part.

Head-to-Head Benchmarks

The benchmark results show a clean sweep for the AMD Ryzen 3 PRO 4355GE, though every victory is marginal. In Cinebench R15 multi-core, the Ryzen scores 904 against the Xeon’s 901, a 0.3% advantage. The single-core R15 test is a perfect tie at 127 points for both chips. Moving to Cinebench R20, the Ryzen leads by 0.3% in multi-core (3769 vs 3757) and by 0.4% in single-core (532 vs 530). The R23 suite mirrors this pattern: the Ryzen wins multi-core 8975 to 8946 (0.3%) and single-core 1267 to 1263 (0.3%).

The most striking observation is the consistency of the margin. Across six tests, the largest delta is 0.4%, and the Ryzen’s biggest win is a mere 29 points in R23 multi-core. The Xeon’s 10 cores and 20 threads provide no measurable advantage in multi-threaded workloads, while the Ryzen’s higher boost clock (4.00 GHz vs 2.60 GHz) yields only a negligible single-core edge. The data suggests these CPUs are interchangeable for Cinebench rendering tasks, with the Ryzen’s architectural efficiency fully compensating for its 60% reduction in core count.

In the broader rival context, both chips sit within a tight cluster. The Ryzen’s nearest rival, the Intel Core i7-8850H, scores 2604 — just 0.3% higher — while the Xeon E-2174G scores 2588, a 0.3% gap from the Ryzen. The Xeon E5-4620 v3’s own nearest rival list shows the same names, with the Ryzen at 2596 (0.3% above) and the Core i7-8850H at 2604 (0.7% above). Neither processor distinguishes itself within this peer group; they are effectively tied for mid-pack performance.

Architecture Differences

The architectural chasm between these two parts is vast, yet it produces no performance separation. The AMD Ryzen 3 PRO 4355GE is built on TSMC’s 7 nm process using the Zen 2 architecture (codename Renoir), packing 9,800 million transistors into a 156 mm² die. It features 4 cores and 8 threads, with base and boost clocks of 3.50 GHz and 4.00 GHz respectively. Its cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and 4 MB shared L3. The chip runs at a 35W TDP and supports dual-channel DDR4 memory with 51.2 GB/s bandwidth. It includes Radeon Vega 6 integrated graphics and offers 16 PCIe Gen 3 lanes.

The Intel Xeon E5-4620 v3, by contrast, is a Haswell-EP part from 2015, fabricated on Intel’s 22 nm process with 2,600 million transistors across a 356 mm² die. It provides 10 cores and 20 threads, with a base clock of 2.00 GHz and boost up to 2.60 GHz. L1 cache is 64 KB per core, L2 is 256 KB per core, and L3 is a substantial 25 MB shared. Its TDP is 105W, and it supports quad-channel DDR4 memory with 59.7 GB/s bandwidth. It has no integrated graphics and offers 40 PCIe Gen 3 lanes.

The process node difference alone — 7 nm vs 22 nm — explains the Ryzen’s ability to match a processor with 2.5 times the cores and 3 times the TDP. The Xeon counters with a 6.25 times larger L3 cache and quad-channel memory bandwidth that is 16.6% higher, yet these advantages fail to translate into Cinebench wins. The Ryzen’s newer architecture extracts more instructions per clock, while the Xeon’s older Haswell design relies on brute core count. The Xeon is marked as end-of-life, while the Ryzen remains in active production.

The Verdict

The data supports a straightforward conclusion: the AMD Ryzen 3 PRO 4355GE is the better processor for every benchmark tested, but the margin is so thin that the choice should be driven by platform needs rather than raw performance. The Ryzen wins all six head-to-head tests, yet the largest victory is 0.4%. In real-world terms, these differences are imperceptible.

For a desktop or low-power workstation, the Ryzen 3 PRO 4355GE is the clear pick. It matches the Xeon’s multi-core throughput while consuming 35W instead of 105W, runs on the ubiquitous AM4 socket, and includes Radeon Vega 6 graphics — eliminating the need for a discrete GPU. Its active production status and 2022 release date mean it remains a viable current product.

The Xeon E5-4620 v3 serves a different purpose. Its quad-channel memory (59.7 GB/s vs 51.2 GB/s) and 40 PCIe lanes (vs 16) make it more suitable for memory-bandwidth-sensitive server workloads or systems requiring extensive I/O expansion. The 25 MB L3 cache could benefit certain database or virtualization scenarios. However, its end-of-life status, 105W TDP, and 2015 release date make it a legacy option. The launch MSRP of the Xeon E5-4620 v3 was $1668. The Ryzen’s average benchmark score of 2596 vs the Xeon’s 2587 — a 0.3% gap — does not justify selecting the older part unless its specific platform features are essential.

Where Each One Wins

The AMD Ryzen 3 PRO 4355GE wins every single benchmark in the head-to-head comparison, but its real advantages lie outside raw scores. It wins on efficiency, with a 35W TDP versus 105W, making it suitable for compact or passively cooled systems. The integrated Radeon Vega 6 graphics provide a complete platform without a discrete GPU. Its 7 nm Zen 2 architecture and active production status ensure ongoing availability. The Ryzen’s 4.00 GHz boost clock gives it a slight edge in all single-core tests, even if the margin is only 0.4% at most.

The Intel Xeon E5-4620 v3 wins in platform capability. Its quad-channel memory interface delivers 59.7 GB/s bandwidth, which is 16.6% higher than the Ryzen’s 51.2 GB/s. It offers 40 PCIe Gen 3 lanes versus 16, enabling more expansion cards, NVMe drives, or networking hardware. The 25 MB L3 cache is 6.25 times larger than the Ryzen’s 4 MB, potentially benefiting workloads with large working sets. The Xeon’s 10 cores and 20 threads provide headroom for heavily threaded server tasks, even if Cinebench does not reflect this advantage. For a server or workstation requiring maximum memory bandwidth and I/O, the Xeon’s 2015-era features remain relevant. The data shows the Ryzen is the better all-around performer, but the Xeon retains a niche for specific enterprise workloads.
