AMD EPYC 7F32 vs Intel Xeon W-2170B Comparison

Intel Xeon W-2170B and AMD EPYC 7F32 both sit at the 61st percentile in the database, yet their benchmark profiles tell very different stories. The Intel part wins every recorded Cinebench test, with deltas ranging from 4.9% to 5%, while the AMD part counters with architectural advantages in memory bandwidth, PCIe connectivity, and manufacturing process. The data shows a clear split: the Xeon W-2170B is the stronger compute engine for single-socket rendering, while the EPYC 7F32 brings platform-level features that matter for server workloads.

Where Each One Wins

The Intel Xeon W-2170B wins outright in raw compute performance across all six head-to-head Cinebench tests. In multi-core tests, the lead is consistent: 4.9% in both Cinebench R15 and R23, and 5% in R20. Single-core results follow the same pattern, with the Xeon ahead by 5% in R15, R20, and R23. The largest absolute gap appears in Cinebench R23 multi-core, where the Xeon scores 20,693 against the EPYC's 19,718, a difference of 975 points.

The AMD EPYC 7F32 wins on platform capabilities, though not on any recorded benchmark. It offers eight-channel memory support versus quad-channel, delivering 204.8 GB/s of bandwidth compared to 85.3 GB/s. The EPYC also provides PCIe Gen 4 with 128 lanes, while the Xeon provides PCIe Gen 3 with 48 lanes. For workloads that saturate memory or require many high-speed expansion devices, the EPYC's platform advantages are substantial, even if Cinebench does not capture them.

The database's nearest rival comparisons reinforce this split. The Xeon W-2170B's average benchmark score of 5,985 places it close to the Intel Core i9-9920X (5,917, 1.1% delta) and AMD EPYC 7451 (5,915, 1.2% delta). The EPYC 7F32's average of 5,703 sits near the AMD EPYC 7351 (5,710, -0.1% delta) and Intel Core i9-7920X (5,673, 0.5% delta). Both processors are mid-pack performers in their respective peer groups.

Architecture Differences

The Xeon W-2170B uses Intel's Skylake-W architecture on a 14 nm process, with a die size of 484 mm². It packs 14 cores and 28 threads, with a base clock of 2.50 GHz and a boost clock of 4.30 GHz. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 19.25 MB of shared L3. The thermal design power is 140 W, and the chip is end-of-life, released in December 2017.

The EPYC 7F32 uses AMD's Zen 2 architecture, codenamed Rome, on a 7 nm process from TSMC. It contains 8 cores and 16 threads, with a base clock of 3.70 GHz and a boost clock of 3.90 GHz. The transistor count is 15,200 million across four dies, each measuring 74 mm². The cache layout differs significantly: 64 KB of L1 per core, 512 KB of L2 per core, 32 MB of L3 per die, and 128 MB of total L3. The TDP is higher at 180 W, and the chip remains active in production, released in April 2020.

The most striking architectural difference is the process node: Intel at 14 nm versus AMD at 7 nm. The EPYC's smaller process allows for a higher base clock (3.70 GHz versus 2.50 GHz) despite having fewer cores, but the Xeon's boost clock is higher (4.30 GHz versus 3.90 GHz). The EPYC's total L3 cache of 128 MB dwarfs the Xeon's 19.25 MB, which could benefit workloads with large working sets.

Memory and I/O also diverge sharply. The EPYC supports eight-channel DDR4 with 204.8 GB/s bandwidth, while the Xeon supports quad-channel DDR4 with 85.3 GB/s. The EPYC's PCIe Gen 4 with 128 lanes is a full generation ahead and offers more than double the lane count of the Xeon's PCIe Gen 3 with 48 lanes. Both processors support ECC memory, and neither includes integrated graphics.

Specification Differences

The two processors differ across nearly every core specification. The Xeon W-2170B has 14 cores and 28 threads, while the EPYC 7F32 has 8 cores and 16 threads. Base clocks are 2.50 GHz for Intel and 3.70 GHz for AMD, while boost clocks are 4.30 GHz and 3.90 GHz respectively. The TDP is 140 W for Intel and 180 W for AMD.

The process nodes are generations apart: 14 nm for Intel's Skylake-W versus 7 nm for AMD's Zen 2. The die sizes reflect this: 484 mm² for the monolithic Intel die versus 4x 74 mm² for AMD's chiplet design. The EPYC's transistor count is listed at 15,200 million, while the Xeon's is not recorded.

Cache configurations differ substantially. The Xeon has 1 MB of L2 per core and 19.25 MB of shared L3. The EPYC has 512 KB of L2 per core and 128 MB of total L3, arranged as 32 MB per die. Both have 64 KB of L1 per core.

Memory and PCIe are where the EPYC pulls ahead. The Xeon supports quad-channel DDR4 with 85.3 GB/s bandwidth, while the EPYC supports eight-channel DDR4 with 204.8 GB/s. The Xeon provides PCIe Gen 3 with 48 lanes; the EPYC provides PCIe Gen 4 with 128 lanes. Both support ECC memory and neither has integrated graphics.

The sockets differ, with the Xeon using Intel Socket 2066 and the EPYC using AMD Socket SP3. The Xeon's part number is SR3W3, and the EPYC's is 100-000000139. The EPYC has a recorded launch MSRP of $2100, while the Xeon's launch MSRP is not available. The Xeon was released in December 2017 and is end-of-life; the EPYC was released in April 2020 and is active.

Head-to-Head Benchmarks

The Xeon W-2170B wins all six head-to-head Cinebench tests, with margins between 4.9% and 5%. In Cinebench R15 multi-core, the Xeon scores 2,085 against the EPYC's 1,987, a 4.9% lead. The single-core R15 result shows 294 versus 280, a 5% margin. The Xeon's advantage is nearly identical across every test, suggesting a consistent per-core performance edge.

Cinebench R20 multi-core shows the Xeon at 8,691 and the EPYC at 8,281, a 5% difference. Single-core R20 follows with 1,226 versus 1,168, again 5%. The largest absolute gap is in Cinebench R23 multi-core: 20,693 for Intel and 19,718 for AMD, a 4.9% delta. Single-core R23 shows 2,921 versus 2,783, a 5% margin.

The consistency of these deltas is notable. Every single-core test shows exactly 5% or 5% rounded, and every multi-core test shows either 4.9% or 5%. This indicates the Xeon's advantage comes from a combination of higher boost clock (4.30 GHz versus 3.90 GHz) and more cores (14 versus 8), though the per-core performance gap is what drives the single-core results.

The EPYC's higher base clock (3.70 GHz versus 2.50 GHz) does not translate into benchmark wins, likely because Cinebench leverages boost clocks and multi-core scaling. The EPYC's 8 cores and 16 threads are simply outmatched by the Xeon's 14 cores and 28 threads in multi-core tests, and the Xeon's higher boost clock wins in single-core tests.

The Verdict

The Intel Xeon W-2170B is the clear choice for compute-bound rendering workloads. It wins every recorded Cinebench test, with a consistent 5% margin in single-core and a 4.9% to 5% margin in multi-core. Its 14 cores and 28 threads provide a substantial parallel processing advantage over the EPYC's 8 cores and 16 threads. For users running Cinebench or similar CPU-heavy tasks, the Xeon delivers measurably higher performance.

The AMD EPYC 7F32 is the better platform choice for memory and I/O intensive server workloads. Its eight-channel memory support and 204.8 GB/s bandwidth more than double the Xeon's quad-channel 85.3 GB/s. The PCIe Gen 4 interface with 128 lanes is a generational leap over PCIe Gen 3 with 48 lanes. These features matter for data-heavy applications, virtualization, and systems with many expansion cards, even though Cinebench does not reflect them.

The production status favors the EPYC, which remains active, while the Xeon is end-of-life. The EPYC's 7 nm process and 128 MB of L3 cache suggest better energy efficiency per core and potentially better cache-sensitive performance, though the recorded benchmarks do not show it. The Xeon's 14 nm process and higher boost clock give it a raw speed advantage that Cinebench captures clearly.

For a workstation focused on rendering and single-threaded responsiveness, the Xeon W-2170B wins on every measured metric. For a server requiring maximum memory bandwidth, PCIe expansion, and a modern active platform, the EPYC 7F32 offers superior infrastructure. The data does not support calling one universally better; the choice depends on whether the workload prioritizes compute speed or platform throughput.
