AMD Ryzen 3 PRO 4350G vs Intel Xeon E5-4627 v3 Comparison

The data shows a remarkably consistent picture: the Intel Xeon E5-4627 v3 wins every single head-to-head benchmark against the AMD Ryzen 3 PRO 4350G, but the margins are uniformly narrow. Across all six Cinebench tests, the Intel part’s advantage ranges from 3.7% to 3.8%, a gap that is measurable but hardly decisive. In terms of overall average benchmark score, the Xeon sits at 2789 against the Ryzen’s 2774, a difference of just 0.5%, placing both processors at the 51st percentile of all CPUs. The competition is tight enough that the Ryzen 3 PRO 4350G’s nearest rival list includes the Intel Core i7-5930K with a deltaPct of 0, meaning the two chips are effectively tied in aggregate performance.

Head-to-Head Benchmarks

The Intel Xeon E5-4627 v3 takes the win in Cinebench R15 multicore with a score of 971 against the Ryzen’s 936, a 3.7% edge. The single-core test in R15 shows a similar story: 137 for Intel versus 132 for AMD, a 3.8% difference. Moving to Cinebench R20, the Xeon posts 4049 in multicore while the Ryzen manages 3900, again a 3.8% lead. The single-core R20 result is 571 versus 550, maintaining that exact 3.8% delta. In the newer Cinebench R23 workload, the pattern holds perfectly: the Xeon scores 9642 in multicore and 1361 in single-core, while the Ryzen scores 9287 and 1311 respectively, with both deltas sitting at 3.8%.

The consistency is striking. Every single benchmark, from the older R15 to the more demanding R23, produces the same relative outcome. The Xeon’s largest win is 3.8%, and its smallest is 3.7%. There is no workload in this suite where the Ryzen even comes close to flipping the result. However, the absolute gaps are small: 35 points in R15 multicore, 149 points in R20 multicore, and 355 points in R23 multicore. For context, the Xeon’s average benchmark score of 2789 places it just 0.1% behind the Intel Core i5-11300H and 0.6% behind the Intel Core i5-8600K. The Ryzen’s average of 2774 puts it 0.1% behind the Intel Xeon D-1567 and 0.3% behind the AMD Ryzen 3 5400U. These are chips trading blows within a very narrow performance band.

Architecture Differences

The two processors come from radically different eras and design philosophies. The Intel Xeon E5-4627 v3 is a Haswell-EP part built on Intel’s 22 nm process, with a 356 mm² die containing 2,600 million transistors. It packs 10 cores and 20 threads, with a base clock of 2.60 GHz and a boost clock of 3.20 GHz. The cache hierarchy includes 64 KB of L1 per core and 256 KB of L2 per core, backed by 25 MB of shared L3 cache. The Xeon supports quad-channel DDR4 memory with a theoretical bandwidth of 68.3 GB/s and offers 40 PCIe Gen 3 lanes from the CPU. It is a server/workstation part, launched on May 31, 2015, with a launch MSRP of $2225, and is now end-of-life.

The AMD Ryzen 3 PRO 4350G is a Zen 2 Renoir desktop chip built on TSMC’s 7 nm process, with a 156 mm² die containing 9,800 million transistors. It has 4 cores and 8 threads, running at a base clock of 3.80 GHz and a boost clock of 4.00 GHz. Its cache setup uses 64 KB of L1 per core, 512 KB of L2 per core, and just 4 MB of shared L3. Memory support is dual-channel DDR4 with 51.2 GB/s of bandwidth, and the CPU provides 16 PCIe Gen 3 lanes. The Ryzen includes integrated Radeon Vega 6 graphics, a feature the Xeon lacks entirely. It launched on July 20, 2020, remains active in production, and its market segment is desktop.

The transistor counts tell a fascinating story. The AMD chip has nearly four times as many transistors (9,800 million versus 2,600 million) on less than half the die area (156 mm² versus 356 mm²), a direct consequence of the 7 nm versus 22 nm process gap. The Xeon compensates with brute core count: 10 cores versus 4, and 20 threads versus 8. The cache differences are just as stark. The Xeon’s 25 MB of L3 is over six times larger than the Ryzen’s 4 MB, and the Xeon’s quad-channel memory bus provides 33% more theoretical bandwidth. Yet the Ryzen’s much higher clocks—3.80 GHz base and 4.00 GHz boost versus 2.60 GHz and 3.20 GHz—narrow the practical gap.

Where Each One Wins

The Intel Xeon E5-4627 v3 wins every benchmark in this comparison, but the margins are so slim that the practical implications depend heavily on the broader system. The Xeon’s advantage in multi-core workloads is real but modest: it leads by 3.7% in R15 multicore, 3.8% in R20 multicore, and 3.8% in R23 multicore. This is a chip with double the core count of the Ryzen, yet it only manages a 3.8% lead in heavily threaded tests. That suggests the Ryzen’s higher clocks and newer architecture are doing heavy lifting to compensate for the 6-core deficit.

For single-core performance, the Xeon also wins, but again by the same 3.8% margin across R15, R20, and R23. This is notable because single-core performance typically favors newer architectures with higher IPC. The Ryzen’s 4.00 GHz boost clock should give it an edge in lightly threaded tasks, but the data shows the Xeon’s older Haswell cores still edge ahead by a consistent 3.8%. The Ryzen does have one advantage not captured in these benchmarks: integrated Radeon Vega 6 graphics. The Xeon has no integrated graphics at all, meaning any system built around it requires a discrete GPU.

The Ryzen also holds a significant platform advantage in power and size. Its 65 W TDP is less than half the Xeon’s 135 W, and it uses the ubiquitous AMD Socket AM4 rather than the server-oriented Intel Socket 2011-3. The Ryzen’s dual-channel memory bus is simpler and cheaper to populate, while the Xeon’s quad-channel setup demands more DIMMs to reach full bandwidth. The Xeon’s 40 PCIe Gen 3 lanes versus the Ryzen’s 16 lanes favor the server chip for expansion-heavy workloads, but the Ryzen’s active production status and newer release date mean it is far easier to source today.

The Verdict

The benchmark data is unambiguous: the Intel Xeon E5-4627 v3 wins all six head-to-head tests against the AMD Ryzen 3 PRO 4350G. If raw Cinebench performance is the sole criterion, the Xeon is the pick, but the margin is a consistent 3.8% or less—hardly a generational leap. The Xeon’s average benchmark score of 2789 versus the Ryzen’s 2774 places them in the same percentile (51st), and the Ryzen’s nearest rival list includes the Xeon’s own peer, the Intel Core i7-5930K, at a 0% delta.

The choice hinges on context. For a server or workstation that can leverage 10 cores, 20 threads, 25 MB of L3, quad-channel memory, and 40 PCIe lanes, the Xeon offers a measurable edge in every tested metric. Its 135 W TDP is a cost of that capability, and its end-of-life status means it is a legacy buy. For a desktop system where integrated graphics can eliminate the need for a discrete GPU, the Ryzen’s Radeon Vega 6 is a decisive feature that the Xeon cannot match. The Ryzen’s 65 W TDP, active production status, and modern 7 nm process make it the more practical choice for most users, despite trailing in every benchmark.

Strictly from the data, the Xeon wins on performance, but the Ryzen wins on platform modernity and efficiency. The 3.8% benchmark deltas are small enough that real-world differences will be hard to notice outside of prolonged all-core rendering. The Xeon’s launch MSRP of $2225 reflects its server heritage, but that figure is historical, and the chip is end-of-life. The Ryzen’s lack of a launch MSRP in the data means no direct price comparison is possible. The verdict is a split: performance purists with server-grade workloads should take the Xeon; everyone else should take the Ryzen for its integrated graphics, lower power draw, and active lifecycle.
