AMD Ryzen 7 4980U vs Intel Xeon W-2133 Comparison

Intel Xeon W-2133 and AMD Ryzen 7 4980U represent two fundamentally different approaches to computing: a workstation-class Intel part designed for sustained multi-threaded throughput versus a mobile AMD processor optimized for efficiency. The benchmark data shows a fascinating split, with each CPU claiming victories in different Cinebench tests. The Intel Xeon W-2133, a 6-core Skylake-W part, and the AMD Ryzen 7 4980U, an 8-core Zen 2 Renoir chip, land in the same 52nd percentile of all CPUs, yet their performance profiles diverge sharply depending on the workload generation. This analysis examines their head-to-head results, architectural philosophies, and specification differences to determine which processor excels in which scenario.

Head-to-Head Benchmarks

The most striking result comes from Cinebench R15 multicore, where the AMD Ryzen 7 4980U delivers a decisive victory. The AMD part scores 1658 against the Intel Xeon's 1075, a 35.2% advantage. This is a substantial margin, reflecting the Ryzen's 8 cores and 16 threads versus the Xeon's 6 cores and 12 threads. The Ryzen's higher boost clock of 4.40 GHz, compared to the Xeon's 3.90 GHz, further amplifies its lead in this test. In single-core R15, the Ryzen again takes the win, scoring 182 versus 151, a 17% difference. This result indicates that the Zen 2 architecture's per-core performance, even at a lower base clock of 2000.00 MHz, outpaces the older Skylake design in this generation of the benchmark.

However, the tables turn dramatically in the newer Cinebench R23 tests. The Intel Xeon W-2133 wins multicore R23 with a score of 10676, beating the Ryzen's 9164 by 16.5%. This reversal is notable because the Ryzen had a 35.2% lead in R15 multicore. The Xeon's 8.25 MB of shared L3 cache, combined with its quad-channel memory bus delivering 85.3 GB/s of bandwidth, likely helps it scale better in the more demanding R23 workload. The Ryzen's dual-channel LPDDR4 memory, capped at 34.1 GB/s, becomes a bottleneck in this test. In R23 single-core, the Xeon also prevails, scoring 1507 versus 1260, a 19.6% margin. This is a surprising outcome given the Ryzen's R15 single-core win, suggesting that the Xeon's architecture handles the R23 instruction mix more efficiently per clock.

The average benchmark scores are nearly identical, with the Xeon at 3087 and the Ryzen at 3066. The closest rival to the Xeon is the Intel Core i7-8700B with an average score of 3086 and a 0% delta, while the Ryzen's nearest competitor is the Intel Xeon E5-2618L v3 at 3066 with a 0% delta. Both CPUs sit in a crowded performance envelope, but their win distribution is polarized. The Ryzen dominates older Cinebench versions, while the Xeon takes the newer ones. This split suggests that the Xeon's higher memory bandwidth and larger L3 cache provide a tangible benefit in modern rendering workloads, while the Ryzen's core count and clock speed advantage shine in legacy tests.

Where Each One Wins

The AMD Ryzen 7 4980U is the clear winner for legacy multi-threaded applications and single-threaded tasks that rely on raw clock speed. Its 35.2% lead in R15 multicore demonstrates that for older software, the 8-core/16-thread configuration with a 4.40 GHz boost clock is exceptionally potent. The 17% advantage in R15 single-core further confirms that the Zen 2 core design, despite its lower base clock, delivers superior instructions per clock in that benchmark generation. This makes the Ryzen a strong choice for users running legacy productivity suites or older rendering engines that predate Cinebench R23's optimizations.

The Intel Xeon W-2133, conversely, is the winner for modern, memory-intensive workloads. Its 16.5% victory in R23 multicore indicates that the combination of a 6-core/12-thread setup with 8.25 MB of shared L3 cache and quad-channel DDR4 memory is better suited to contemporary rendering tasks. The 19.6% lead in R23 single-core is even more telling, as it suggests the Xeon's Skylake architecture handles the newer instruction set more effectively when memory bandwidth is not a constraint. For users running current 3D rendering, video encoding, or scientific simulations that leverage large datasets, the Xeon's superior memory subsystem provides a tangible performance edge.

In terms of overall percentile ranking, both CPUs sit at the 52nd percentile, meaning they perform better than roughly half of all CPUs in the database. The Ryzen's nearest rivals include the AMD Ryzen 7 1800X with a -0.1% delta, while the Xeon's include the Intel Core i7-6850K with a 0.3% delta. These close margins indicate that both chips are competitive within their respective market tiers, but the choice between them hinges on the specific benchmark generation and workload type. The Xeon is a workstation part that excels in sustained, modern multi-threaded tasks, while the Ryzen is a mobile part that punches above its weight in legacy tests and single-threaded scenarios.

Architecture Differences

The architectural gulf between these two processors is vast. The Intel Xeon W-2133 is built on the Skylake-W architecture using a 14 nm process node from Intel, with a die size of 484 mm². This is a large, power-hungry design intended for server and workstation platforms. The AMD Ryzen 7 4980U, in contrast, uses the Zen 2 architecture on a 7 nm TSMC process, with a die size of just 156 mm². The process node difference is critical: the 7 nm node allows AMD to pack 9,800 million transistors into a much smaller die, enabling higher core counts and lower power consumption. The Xeon's 14 nm node, while mature, is less efficient per transistor.

Cache hierarchies also diverge significantly. Both CPUs have 64 KB of L1 cache per core, but the L2 cache differs: the Xeon has 1 MB per core, while the Ryzen has 512 KB per core. This means the Xeon has a total of 6 MB of L2 cache, while the Ryzen has 4 MB. However, the Xeon's L3 cache is 8.25 MB shared, slightly larger than the Ryzen's 8 MB shared. The Xeon's larger per-core L2 cache may help with certain workloads, but the Ryzen's smaller die and newer process allow for faster access times. The memory controller is another key difference: the Xeon supports quad-channel DDR4 with 85.3 GB/s of bandwidth, while the Ryzen uses dual-channel LPDDR4 with only 34.1 GB/s. This 2.5x bandwidth advantage for the Xeon is a major architectural differentiator.

The Xeon also supports ECC memory, a feature absent on the Ryzen, making it suitable for error-sensitive server workloads. The Ryzen, however, includes integrated Radeon Graphics with 512 SPs, a feature the Xeon lacks entirely. The Xeon's PCIe implementation is Gen 3 with 48 lanes from the CPU, while the Ryzen offers Gen 3 without a lane count specified, though it's typically fewer for mobile parts. The Xeon's socket is Intel Socket 2066, while the Ryzen uses AMD Socket FP6, reflecting their different market segments: the Xeon is a server/workstation part, and the Ryzen is a mobile part.

Specification Differences

The specification sheets reveal stark contrasts in almost every category. The core count differs by two: the Xeon has 6 cores, while the Ryzen has 8. Thread counts follow suit, with 12 threads on the Xeon and 16 on the Ryzen. Base clocks are dramatically different: the Xeon runs at 3.60 GHz, while the Ryzen's base clock is listed as 2000.00 MHz, a significant 1.6 GHz gap. Boost clocks reverse the trend, with the Ryzen boosting to 4.40 GHz versus the Xeon's 3.90 GHz. This means the Ryzen has a wider clock range, which helps it achieve high single-thread performance while maintaining low idle power.

The thermal design power (TDP) is the most extreme difference. The Xeon has a TDP of 140 W, while the Ryzen is rated at just 15 W. This is a 125 W difference, making the Ryzen nearly ten times more power-efficient on paper. The Xeon's high TDP is necessary to feed its 484 mm² die and quad-channel memory controller, while the Ryzen's 156 mm² die and dual-channel setup allow for ultra-low power consumption. Memory support differs as well: the Xeon uses DDR4, while the Ryzen uses LPDDR4, reflecting the mobile vs. workstation design goals. ECC memory is supported on the Xeon but not the Ryzen.

The Xeon's release date is 2017-08-28, while the Ryzen's is 2021-04-12, a gap of nearly four years. This explains the process node advantage for the Ryzen. The Xeon's launch MSRP is $617, while the Ryzen has no listed MSRP. The Xeon's part number is SR3LL, and the Ryzen's is 100-000000354. Both CPUs are end-of-life and have locked multipliers. The Xeon's market segment is "Server/Workstation," while the Ryzen's is "Mobile." The Xeon's socket is Intel Socket 2066, and the Ryzen's is AMD Socket FP6. The Xeon's memory bus is quad-channel, while the Ryzen's is dual-channel.
