AMD Ryzen 5 PRO 3500U vs Intel Xeon W3550 Comparison

Where Each One Wins

The recorded data splits these two processors into sharply different roles. The Intel Xeon W3550 is a legacy workstation part, and its benchmark presence is built entirely around multi-threaded rendering loads in the Cinebench suite. The AMD Ryzen 5 PRO 3500U, by contrast, is a modern mobile chip whose results cover both multi-core and single-core workloads, plus Geekbench tests. The only direct head-to-head measurement in the database is Cinebench R15 multi-core, and there the AMD part wins decisively.

For the Xeon W3550, its wins are confined to the older Cinebench R20 and R23 multi-core tests, where it posts scores of 1166 and 2778 respectively. Those are the only benchmark entries where it has a recorded score that the Ryzen 5 PRO 3500U does not also contest. The Ryzen 5 PRO 3500U, meanwhile, holds the single head-to-head victory in Cinebench R15 multi-core, scoring 624 against the Xeon's 279, a delta of -55.3% from the AMD side's perspective. The Ryzen also has recorded wins in Cinebench R15 single-core (142) and both Geekbench tests (2202 multi-core, 819 single-core), none of which the Xeon has an entry for.

The use-case split is therefore stark. The Xeon W3550 is a chip that only shows up in rendering benchmarks from the Cinebench family, and even there it is competitive only in the newer multi-threaded iterations relative to its own historical baseline. The Ryzen 5 PRO 3500U covers a broader test matrix, including single-thread performance, which matters for everyday responsiveness and lightly threaded applications. If the workload is a modern multi-core render, the Ryzen 5 PRO 3500U is the clear choice based on the head-to-head data. If the workload is legacy multi-threaded rendering on an older platform, the Xeon W3550 still has recorded scores, but it does not beat the AMD part anywhere they overlap.

The percentile rankings reinforce this split. The Xeon W3550 sits at the 26th percentile of all CPUs, while the Ryzen 5 PRO 3500U sits at the 25th percentile. These are nearly identical overall positions, which means the average benchmark score tells a similar story: the Xeon averages 956, the Ryzen averages 947. The difference is less than 1%. So neither chip is a performance outlier in the broader database; they are both mid-to-low tier parts. The wins are situational, not categorical.

Architecture Differences

The two processors come from different eras and different design philosophies. The Intel Xeon W3550 is built on the Nehalem architecture, codenamed Bloomfield, using a 45 nm process node fabricated by Intel. It packs 731 million transistors on a 263 mm² die. The AMD Ryzen 5 PRO 3500U uses the Zen+ architecture, codenamed Picasso, on a 12 nm process from GlobalFoundries, with 4,940 million transistors on a 210 mm² die. The transistor count difference is enormous: the AMD chip has nearly seven times as many transistors on a smaller die, which reflects the dramatic density improvements between 2009 and 2019.

Cache layouts also differ. The Xeon W3550 has 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. The Ryzen 5 PRO 3500U has 96 KB of L1 per core, 512 KB of L2 per core, but only 4 MB of shared L3. The AMD part has more per-core cache in the first two levels but half the shared L3. For workloads that thrash a large shared cache, the Xeon has the advantage; for per-core working sets, the Ryzen is better provisioned.

Memory support diverges completely. The Xeon W3550 uses DDR3 with a triple-channel memory bus and supports ECC memory. The Ryzen 5 PRO 3500U uses DDR4 with a dual-channel bus, a recorded memory bandwidth of 38.4 GB/s, and no ECC support. The Xeon is a server/workstation part, so ECC is expected. The Ryzen is a mobile part, so ECC is absent. The PCIe generation also differs: the Xeon has Gen 2, the Ryzen has Gen 3. The Ryzen also includes integrated graphics, specifically Radeon Vega 8, while the Xeon has no integrated graphics at all.

The production status tells the rest of the story. The Xeon W3550 is end-of-life, released in August 2009, with a part number of SLBEY. The Ryzen 5 PRO 3500U is active, released in April 2019, with part number YM350BC4T4MFG. The Xeon uses Intel Socket 1366; the Ryzen uses AMD Socket FP5. Neither chip has an unlocked multiplier. The Xeon's base clock is 3.07 GHz with a boost of 3.33 GHz, while the Ryzen's base is 2.10 GHz with a boost of 3.70 GHz. The Ryzen has a higher boost ceiling but a much lower base clock, which is typical for a 15 W mobile part versus a 130 W desktop workstation part.

Head-to-Head Benchmarks

The database contains exactly one head-to-head benchmark between these two processors, and it is a one-sided result. In Cinebench R15 multi-core, the AMD Ryzen 5 PRO 3500U scores 624, while the Intel Xeon W3550 scores 279. The delta percentage is -55.3%, which is calculated from the AMD side, meaning the Xeon's score is 55.3% lower than the Ryzen's. This is not a close contest; the Ryzen more than doubles the Xeon's output in this specific render test.

That single result dominates the head-to-head comparison. The Ryzen 5 PRO 3500U has 1 win and 0 losses. The Xeon W3550 has 0 wins and 1 loss. The margin is large enough that no other benchmark overlap exists in the database to complicate the picture. The Xeon's best recorded scores are in Cinebench R20 multi-core (1166) and Cinebench R23 multi-core (2778), but the Ryzen has no entries for those tests, so they cannot be compared directly.

The individual benchmark sets reveal why the average scores are so close despite the head-to-head blowout. The Xeon's five recorded benchmark scores are all from the Cinebench family, with multi-core scores of 279, 1166, and 2778, and single-core scores of 164 and 392. The Ryzen's four recorded scores span Cinebench and Geekbench: 624 in Cinebench R15 multi-core, 142 in Cinebench R15 single-core, 2202 in Geekbench multi-core, and 819 in Geekbench single-core. The Xeon's newer Cinebench scores are higher than its older ones, which suggests the chip scales with newer test versions, but the Ryzen's Geekbench results show a broader capability profile.

The nearest rivals for each chip put the performance in context. The Xeon W3550's closest competitors are the AMD Athlon X4 870K (avg score 956, 0% delta), Intel Core i7-950 (957, -0.1%), Intel Celeron N5105 (955, 0.1%), and Intel Xeon W3570 (955, 0.1%). The Ryzen 5 PRO 3500U's nearest rivals are the Intel Pentium Gold G5400T (946, 0.1%), Intel Xeon X5560 (946, 0.1%), AMD Phenom II X6 1045T (946, 0.1%), and Intel Core i3-1110G4 (945, 0.2%). Neither chip is far from its peers; the deltas are all under 1%. The Xeon's average score of 956 puts it essentially tied with its rivals, and the Ryzen's 947 does the same.

The data indicates that the Ryzen 5 PRO 3500U is the more capable chip where they overlap, but the Xeon W3550 retains relevance in the specific multi-threaded Cinebench tests where it has recorded scores. The 55.3% deficit in the head-to-head test is the single most informative number in the comparison. It shows a generational gap in raw multi-threaded rendering performance, even though both chips have identical core and thread counts. The Ryzen's higher boost clock, newer architecture, and smaller process node all contribute to that result, though the database records only the scores, not the causal chain.
