AMD Ryzen 5 3550H vs Intel Xeon E5-2623 v3 Comparison

Head-to-Head Benchmarks

The most striking result in the direct comparison is the Cinebench R15 multicore test, where the AMD Ryzen 5 3550H scores 742 against 568 for the Intel Xeon E5-2623 v3. That is a 30.6% advantage for the AMD part, a substantial margin in a heavily threaded workload. The single-core R15 gap is even more dramatic: 144 versus 79, a 82.3% lead for the Ryzen. This is the largest delta in the entire head-to-head set and it points to a fundamental difference in how each chip executes legacy single-threaded code.

However, the newer Cinebench R23 benchmark flips the multi-core result. Here the Intel Xeon E5-2623 v3 scores 5637 against 3929.5 for the Ryzen, meaning the Xeon leads by 30.3%. This is a complete reversal from R15, showing that the two CPUs respond very differently to the workload changes in the newer rendering engine. The R23 single-core test goes back to the AMD side, with 886 versus 795, a 11.4% win for the Ryzen 5 3550H.

Across the four shared benchmarks, the AMD chip wins three and the Intel chip wins one. The wins are not close in most cases: the R15 deltas are massive, while the R23 multi-core loss for AMD is equally large. The only narrow margin is the R23 single-core test. The recorded data suggests that the Ryzen 5 3550H is the stronger chip for older workloads and short bursts, while the Xeon E5-2623 v3 pulls ahead in the specific multi-threaded scenario of Cinebench R23.

Looking at the overall average benchmark score, the two are nearly identical. The Ryzen 5 3550H averages 1653, and the Xeon E5-2623 v3 averages 1630. That is a difference of roughly 1.4% in favor of the AMD part, which places both CPUs in the same performance tier despite their very different benchmark profiles.

Where Each One Wins

The AMD Ryzen 5 3550H is the clear winner in single-threaded performance across every test in the database. The R15 single-core score of 144 versus 79 is a 82.3% advantage, and the R23 single-core score of 886 versus 795 is a 11.4% advantage. This makes the Ryzen the better choice for applications that rely on one or two cores, such as older games, spreadsheet work, or lightly threaded productivity tools. The R15 multi-core result also goes to AMD with a 30.6% lead, which suggests that in the older Cinebench engine, the Ryzen handles even multi-threaded tasks more efficiently.

The Intel Xeon E5-2623 v3 takes the R23 multi-core test with a 30.3% margin, scoring 5637 against 3929.5. This is the only benchmark the Xeon wins, but it is a significant one. The R23 engine is more modern and scales differently with memory bandwidth and cache, and the data indicates the Xeon benefits from its larger shared cache and quad-channel memory setup in this specific workload. For users running current-generation rendering software that behaves like Cinebench R23, the Xeon is the stronger part.

The Ryzen 5 3550H also holds a slight edge in the overall average benchmark score, 1653 versus 1630, which places it just above the Xeon in the aggregate. However, the Xeon's percentile rank of 39 versus the Ryzen's 40 means they sit at essentially the same level relative to all CPUs in the database.

Architecture Differences

The Ryzen 5 3550H is built on AMD's Zen+ architecture, codenamed Picasso, using a 12 nm process at GlobalFoundries. It integrates 4,940 million transistors on a 210 mm² die. The Xeon E5-2623 v3 uses Intel's Haswell architecture, codenamed Haswell-EP, on a 22 nm process at Intel, with 2,600 million transistors on a 356 mm² die. The process node difference is notable: 12 nm versus 22 nm gives the AMD part a density advantage, though the Intel die is physically larger.

Cache configurations differ significantly. The Ryzen 5 3550H has 96 KB of L1 and 512 KB of L2 per core, with 4 MB of shared L3. The Xeon E5-2623 v3 has 64 KB of L1 and 256 KB of L2 per core, but a much larger 10 MB of shared L3. That 10 MB L3 is likely a major factor in the Xeon's R23 multi-core win, as it provides more room for the rendering engine's working set.

The integrated graphics situation is one-sided. The Ryzen 5 3550H includes Radeon Vega 8 graphics, while the Xeon E5-2623 v3 has no integrated graphics at all. This makes the Ryzen a complete package for a mobile system without a discrete GPU, while the Xeon requires a separate graphics card.

Market positioning also differs. The Ryzen is a mobile part with a 35 W TDP, while the Xeon is a server or workstation chip with a 105 W TDP. The production status confirms this: the Ryzen is active, while the Xeon is end-of-life.

Specification Differences

The most immediate difference is clock speed. The Ryzen 5 3550H has a base clock of 2.10 GHz and a boost clock of 3.70 GHz. The Xeon E5-2623 v3 has a base clock of 3.00 GHz and a boost of 3.50 GHz. The Xeon starts higher but boosts lower, while the AMD part has a wider clock range.

Power consumption is a major split. The Ryzen is rated at 35 W TDP, while the Xeon is rated at 105 W TDP. That is a threefold difference in thermal design power, which directly impacts cooling requirements and system design. The Ryzen can be cooled by a modest laptop cooler, while the Xeon demands a serious workstation heatsink or server cooling solution.

Memory support differs in channel count. The Ryzen uses dual-channel DDR4, while the Xeon uses quad-channel DDR4 with a rated memory bandwidth of 59.7 GB/s. The Ryzen has no listed memory bandwidth figure in the database, but the channel difference is clear. The Xeon also supports ECC memory, while the Ryzen does not.

PCIe configuration is another differentiator. Both support PCIe Gen 3, but the Xeon offers 40 lanes (CPU only), while the Ryzen's lane count is not specified in the database. The Xeon's 40 lanes are typical for a server platform with multiple expansion cards. The Ryzen's mobile socket, AMD Socket FP5, contrasts with the Xeon's Intel Socket 2011-3.

The Xeon has a launch MSRP of $444. The Ryzen has no recorded launch MSRP. The Xeon's release date is September 2014, while the Ryzen's is January 2019, nearly four and a half years later.

The Verdict

The data points to a clear split based on workload and platform requirements. If the priority is single-threaded performance, the AMD Ryzen 5 3550H is the better part. It leads by 82.3% in R15 single-core and 11.4% in R23 single-core, and it also wins the R15 multi-core test by 30.6%. For older applications, light multitasking, or any workload that does not scale to many threads, the Ryzen is the stronger choice. Its 35 W TDP and integrated Radeon Vega 8 graphics also make it viable in compact mobile systems with minimal cooling and no discrete GPU.

If the workload looks more like Cinebench R23 multi-core, the Intel Xeon E5-2623 v3 is the winner. Its 30.3% margin in that test, combined with 10 MB of shared L3 cache and quad-channel DDR4 memory with 59.7 GB/s bandwidth, makes it the better fit for modern multi-threaded rendering tasks. The Xeon also supports ECC memory, which is critical for error-sensitive server or workstation applications. The higher 105 W TDP is a trade-off, but it comes with a higher base clock of 3.00 GHz and 40 PCIe Gen 3 lanes, which suit a workstation motherboard with multiple expansion devices.

The overall average benchmark scores are nearly tied, 1653 versus 1630, so neither chip dominates the other in aggregate. The Ryzen 5 3550H is the more versatile and power-efficient part, suited to mobile systems and single-threaded tasks. The Xeon E5-2623 v3 is a specialized server part, now end-of-life, that still delivers strong multi-threaded performance in the right conditions. The choice comes down to whether the workload resembles R15 or R23, and whether the platform can accommodate the Xeon's power and cooling demands.
