Intel Xeon D-2796TE vs Intel Xeon W-2191B Comparison

The Intel Xeon W-2191B and Intel Xeon D-2796TE are both server/workstation processors, but they target different physical and architectural realities. The W-2191B is a high-frequency, older-generation Skylake part with fewer cores, while the D-2796TE is a denser, newer Ice Lake chip with more cores but a much lower clock ceiling. Benchmark data shows the W-2191B wins every single head-to-head test, despite its age and lower core count, while the D-2796TE counters with a smaller footprint, lower TDP, and newer platform features.

The Verdict

The data is unambiguous: the Intel Xeon W-2191B wins all six head-to-head benchmarks, with a consistent 6.1% edge in multi-core tests and a 5.9% to 6.1% edge in single-core tests. If your workload is raw compute performance in Cinebench-style rendering or encoding, the W-2191B is the chip to pick. Its 4.30 GHz boost clock versus the D-2796TE's 3.10 GHz boost clock is the primary driver of this advantage, and it overcomes the D-2796TE's 2-core and 4-thread lead. The average benchmark score confirms this: the W-2191B sits at 6531, essentially tied with the D-2796TE's 6510, with a delta of just 0.3% in favor of the W-2191B.

However, the D-2796TE is the correct choice for a different set of constraints. It has a 118 W TDP versus the W-2191B's 140 W, and it uses a BGA 2579 socket, meaning it is soldered to the board—a system-on-chip approach that saves space and simplifies cooling in dense, rack-mounted deployments. It is an Active production part, while the W-2191B is End-of-life. If you are building a new, power-conscious, always-on server in a compact chassis, the D-2796TE's lower power draw and newer process node make it a more practical platform, even though it loses every benchmark. Choose the W-2191B for performance; choose the D-2796TE for efficiency and longevity.

Architecture Differences

The two chips come from different eras of Intel design. The W-2191B is built on the 14 nm Skylake-W architecture, with a die size of 484 mm², while the D-2796TE uses the 10 nm Ice Lake-D architecture. This node difference is significant: the smaller 10 nm process allows the D-2796TE to pack 20 cores and 40 threads into a lower 118 W TDP, whereas the W-2191B manages 18 cores and 36 threads within a 140 W envelope. The core count advantage for the D-2796TE is real, but it comes with a much lower base clock of 2000.00 MHz and a boost clock of 3.10 GHz, compared to the W-2191B's 2.30 GHz base and 4.30 GHz boost.

Cache layouts also differ. The W-2191B has 64 KB of L1 and 1 MB of L2 per core, with a 24.75 MB shared L3. The D-2796TE scales this up: 80 KB L1 and 1.25 MB L2 per core, and a 30 MB shared L3. The D-2796TE's larger cache pool is a direct result of the newer architecture and higher core count. Memory support is DDR4 for both, and both use quad-channel buses, but bandwidth favors the D-2796TE at 93.9 GB/s versus 85.3 GB/s for the W-2191B. PCIe capability is another split: the W-2191B offers Gen 3 with 48 lanes, while the D-2796TE offers Gen 4 with 32 lanes. The D-2796TE's Gen 4 interface doubles per-lane throughput, which matters for NVMe storage and accelerators, despite fewer total lanes. Both support ECC memory, and neither has integrated graphics. The W-2191B was released on 2017-12-20, while the D-2796TE followed on 2022-02-23.

Head-to-Head Benchmarks

The head-to-head data tells a consistent story of W-2191B dominance. In Cinebench R15 multi-core, the W-2191B scores 2407 against the D-2796TE's 2268, a 6.1% delta. Single-core R15 shows a similar pattern: 339 versus 320, a 5.9% delta. The R20 tests yield identical deltas—6.1% for both multi-core and single-core—with scores of 10032 versus 9452 and 1416 versus 1334, respectively. The R23 results maintain the pattern: multi-core 23887 versus 22507 and single-core 3372 versus 3177, both at a 6.1% delta.

The consistency of the 6.1% margin across multi-core tests is striking. It suggests that the W-2191B's boost clock advantage scales uniformly across all core counts, despite the D-2796TE having two more cores. In single-core tests, the W-2191B's 4.30 GHz boost clock provides a 5.9% to 6.1% edge, which is directly attributable to the clock speed difference. The W-2191B wins all six benchmarks, with a total win count of 6 for the W-2191B and 0 for the D-2796TE. The average benchmark scores align with this: the W-2191B averages 6531, and the D-2796TE averages 6510, a 0.3% gap in favor of the W-2191B. Notably, the W-2191B also has a Geekbench multi-core score of 9614 and a single-core score of 1182, which are not available for the D-2796TE, further widening the performance data gap.

Where Each One Wins

The W-2191B wins in every measured performance category. It takes the crown in all Cinebench R15, R20, and R23 tests, both multi-core and single-core. This makes it the clear choice for any workload that is CPU-bound and scales with clock speed, such as single-threaded applications, lightly threaded simulations, or tasks where a high boost clock reduces latency. Its 4.30 GHz boost clock is the highest among the two, and it delivers a 6.1% multi-core advantage in R23, which translates to faster renders and compiles. For users with an existing Socket 2066 motherboard, the socketed design offers upgrade flexibility, though the End-of-life status limits future drop-in replacements.

The D-2796TE wins on platform attributes rather than raw speed. Its 118 W TDP is 22 W lower, making it easier to cool in passive or low-noise server chassis. The 10 nm Ice Lake architecture provides a 30 MB shared L3 cache, which is 5.25 MB more than the W-2191B, potentially benefiting workloads with large working sets that fit in cache. Its memory bandwidth of 93.9 GB/s surpasses the W-2191B by 8.6 GB/s, which is advantageous for memory-intensive tasks like database operations or in-memory analytics, even if the compute cores are slower. The Gen 4 PCIe interface with 32 lanes offers double the per-lane bandwidth of the W-2191B's Gen 3, meaning faster connections for modern NVMe SSDs and GPUs, despite having 16 fewer lanes. The D-2796TE is Active, so it remains in production for new system designs, and its BGA 2579 soldered form factor is ideal for dense, embedded deployments where space is at a premium. Ultimately, the W-2191B is the performance pick, while the D-2796TE is the efficiency and platform-feature pick.
