Intel Xeon Gold 6154 vs Intel Xeon W-2191B Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent, though narrow, victory for the Intel Xeon W-2191B across every benchmark in the head-to-head comparison. The W-2191B wins all six recorded tests, with the Xeon Gold 6154 trailing in each instance. The largest margin appears in Cinebench R15 multi-core, where the W-2191B scores 2407 against the Gold 6154's 2370, a 1.6% advantage. That same 1.6% delta repeats in Cinebench R20 multi-core (10032 vs 9878) and Cinebench R23 multi-core (23887 vs 23521).

Single-core results follow the same pattern. The W-2191B leads in Cinebench R15 single-core with 339 points versus 334, a 1.5% gap. Cinebench R20 single-core shows 1416 against 1394, and Cinebench R23 single-core shows 3372 against 3320, both at 1.6% deltas. The consistency of these margins is notable: across five of the six tests, the W-2191B holds exactly a 1.6% lead. Only the R15 single-core test dips slightly to 1.5%.

When placed against the broader field, the average benchmark score for the W-2191B is 6531, while the Gold 6154 averages 6803. This places the W-2191B at the 62nd percentile of all CPUs, with the Gold 6154 at the 63rd percentile. The Gold 6154's higher average score comes from a different benchmark set, as the database includes Geekbench results for the W-2191B (9614 multi-core, 1182 single-core) that are not recorded for the Gold 6154. Within the directly comparable Cinebench tests, the W-2191B is ahead every time, but the Gold 6154's overall standing is one percentile point higher.

The nearest rivals for each processor provide additional context. The W-2191B sits within 0.8% of the Intel Core i9-7960X (6533 average), the Intel Xeon D-2796TE (6510), the Intel Atom x7405C (6568), and the Intel Core i5-13500E (6586). The Gold 6154's closest competitors include the Intel Core i7-12700E (6776, 0.4% behind), the AMD Ryzen Threadripper 2970WX (6760, 0.6% behind), and the AMD Athlon Silver 10 (6849, 0.7% ahead). These deltas show both processors operating in a tightly packed performance tier, where a 1.6% difference between the two is meaningful but not transformative.

FAQ

Q: How many cores and threads does each processor have?

A: Both have 18 cores and 36 threads. They also share identical L1 cache (64 KB per core), L2 cache (1 MB per core), and L3 cache (24.75 MB shared).

Architecture Differences

Both processors are built on Intel's Skylake architecture and manufactured on a 14 nm process node at Intel's foundry. The W-2191B uses the Skylake-W codename and belongs to the Xeon W (Skylake-W) generation, while the Gold 6154 uses the Skylake-SP codename and belongs to the Xeon Gold (Skylake-SP) generation. The underlying core design is the same, but the platform implementations diverge.

The W-2191B has a die size of 484 mm², while the Gold 6154's die size is not recorded. The Gold 6154 does list a transistor count of 8,000 million, while the W-2191B's transistor count is absent from the database. These figures suggest similar physical implementations, though the Gold 6154's explicit transistor count indicates a fully populated die.

The most significant architectural difference lies in the socket and memory configuration. The W-2191B uses Intel Socket 2066 and supports quad-channel DDR4 memory with a recorded memory bandwidth of 85.3 GB/s. The Gold 6154 uses Intel Socket 3647, and its memory bus and bandwidth fields are not recorded. Both support DDR4 and ECC memory, but the W-2191B offers explicit PCIe Gen 3 with 48 lanes (CPU only), while the Gold 6154's PCIe configuration is not listed.

Clock behavior also differs substantially. The W-2191B has a base clock of 2.30 GHz and a boost clock of 4.30 GHz, giving it a 1.00 GHz boost range. The Gold 6154 has a base clock of 3.00 GHz and a boost clock of 3.70 GHz, a narrower 0.70 GHz range. The W-2191B's higher boost ceiling explains its single-core benchmark wins, while the Gold 6154's higher base clock does not translate into multi-core wins in the recorded tests.

Specification Differences

The two processors differ in several recorded specification fields. The W-2191B has a base clock of 2.30 GHz, while the Gold 6154 runs at 3.00 GHz. The boost clocks are 4.30 GHz for the W-2191B and 3.70 GHz for the Gold 6154. Thermal design power differs by 60 watts: the W-2191B is rated at 140 W, the Gold 6154 at 200 W.

The sockets are incompatible: the W-2191B uses Intel Socket 2066, the Gold 6154 uses Intel Socket 3647. The W-2191B lists a die size of 484 mm²; the Gold 6154 lists 8,000 million transistors, with no die size. The W-2191B records a memory bandwidth of 85.3 GB/s and a quad-channel memory bus; the Gold 6154 has neither field populated. The W-2191B specifies PCIe Gen 3 with 48 lanes (CPU only); the Gold 6154 has no PCIe data.

Release dates differ by roughly five months. The Gold 6154 launched on 2017-07-10, while the W-2191B launched on 2017-12-20. The production status for the W-2191B is listed as end-of-life; the Gold 6154's status is not recorded. Part numbers are SR3RW for the W-2191B and SR3J5CD8067303592700 for the Gold 6154. Neither processor has an unlocked multiplier, and neither has integrated graphics.

Where Each One Wins

The Intel Xeon W-2191B wins every directly comparable benchmark in the database. Its advantages are consistent across single-core and multi-core workloads, with a 1.6% lead in most tests and a 1.5% lead in Cinebench R15 single-core. The W-2191B is the clear choice for users prioritizing raw Cinebench performance, whether rendering in multi-threaded scenarios or relying on single-threaded responsiveness. Its higher boost clock of 4.30 GHz, versus 3.70 GHz for the Gold 6154, aligns with these results.

The Gold 6154 does not win any head-to-head test, but its higher average benchmark score of 6803 and 63rd percentile ranking suggest it performs better in the broader benchmark set that includes Geekbench results absent from its direct comparison. The Gold 6154's higher base clock of 3.00 GHz could favor sustained workloads that do not boost, though the recorded data does not isolate that scenario. Its 200 W TDP indicates a higher power envelope, which may suit systems designed for maximum sustained throughput rather than efficiency.

The W-2191B's lower 140 W TDP and explicit 48 PCIe Gen 3 lanes make it a more flexible platform option for workstation builds. The Gold 6154's Socket 3647 platform, with no recorded PCIe or memory bandwidth data, leaves its expansion capabilities unspecified in the database. For users who value the recorded specifications, the W-2191B offers more documented platform features.

The Verdict

From the recorded data, the Intel Xeon W-2191B is the superior processor in every head-to-head benchmark. It wins all six Cinebench tests, including both single-core and multi-core variants, with margins of 1.5% to 1.6%. Users who rely on Cinebench scores as a proxy for rendering or general CPU performance should select the W-2191B without hesitation.

The Intel Xeon Gold 6154 is not without its merits. Its higher average benchmark score of 6803 and 63rd percentile ranking indicate that, across the full recorded benchmark set, it holds a slightly stronger overall position. The Gold 6154's higher base clock of 3.00 GHz may appeal to users running workloads that stay at base frequency for extended periods. Its 200 W TDP suggests it is designed for systems with robust cooling and power delivery.

That said, the Gold 6154 loses every direct comparison. The W-2191B matches it in core count, threads, and cache hierarchy, while surpassing it in boost clock and benchmark scores. The W-2191B's 140 W TDP makes it the more power-efficient choice in the database's recorded specifications. For any workload represented by the Cinebench suite, the W-2191B is the measured winner. The Gold 6154's only advantage lies in its higher average score, which stems from a different benchmark set that includes Geekbench data for one processor but not the other.

The verdict is straightforward: choose the W-2191B for guaranteed benchmark wins, lower power consumption, and a documented PCIe and memory configuration. Choose the Gold 6154 only if the platform requirements demand Socket 3647, or if the higher average score from the broader benchmark set outweighs the direct comparison losses. The data does not support selecting the Gold 6154 on performance grounds within the shared tests.
