Intel Xeon W-1290TE vs Intel Xeon W-2135 Comparison

The Intel Xeon W-1290TE and Intel Xeon W-2135 are both workstation-class processors, but they represent opposite ends of the design spectrum. The W-1290TE is a 10-core, 20-thread part built on the Comet Lake architecture, engineered for power efficiency with a 35 W TDP. The W-2135 is a 6-core, 12-thread Skylake-W processor with a much higher 140 W TDP and a larger physical footprint. Despite these fundamental differences, benchmark data reveals an extraordinarily tight performance parity between the two, with the W-1290TE edging ahead in every single test by a razor-thin margin.

Head-to-Head Benchmarks

The benchmark results are defined by their closeness rather than any decisive victory. In Cinebench R15 multi-core, both processors score exactly 1230 points, resulting in a 0% delta. The single-core R15 test is equally identical, with both parts posting a score of 173. This perfect tie in the older R15 suite suggests that the architectural differences between Comet Lake and Skylake-W have virtually no impact on this particular workload.

Moving to Cinebench R20, the margins become measurable but remain minuscule. The W-1290TE scores 5129 in multi-core, while the W-2135 scores 5126, giving the Comet Lake part a 0.1% advantage. In single-core R20, the W-1290TE again leads by 0.1%, posting 724 against the W-2135's 723. The pattern holds in Cinebench R23, where the W-1290TE achieves 12213 multi-core and 1724 single-core, compared to 12205 and 1723 for the W-2135 respectively—another pair of 0.1% deltas.

The data shows the W-1290TE winning all six head-to-head comparisons, but the magnitude of these wins is statistically negligible. The largest delta across any test is 0.1%, which is within typical run-to-run variance for benchmark software. The W-2135, despite having 4 fewer cores and 8 fewer threads, manages to match the W-1290TE's multi-core output almost exactly. This is a remarkable result given that the W-1290TE has a base clock of 1.80 GHz compared to the W-2135's 3.70 GHz. Both processors share a 4.50 GHz boost clock, which likely explains the single-core parity.

Average benchmark scores reinforce this picture. The W-1290TE averages 3532 across all tests, while the W-2135 averages 3530, a delta of just 0.1%. Both processors sit at the 55th percentile of all CPUs tracked. The nearest rivals list confirms the tight clustering: the Intel Core i3-12300 scores 3532, the Core i5-10600K scores 3533, and the Core i3-12300T scores 3525. The W-1290TE and W-2135 are effectively interchangeable in raw performance, sitting within 0.2% of each other and their closest competitors.

Where Each One Wins

The W-1290TE claims victory in all six head-to-head benchmarks, but the practical significance of these wins is limited. In multi-core workloads, its 10 cores and 20 threads provide a theoretical advantage over the W-2135's 6 cores and 12 threads. The extra cores should allow the W-1290TE to handle more simultaneous threads, yet the benchmark data shows only a 0.1% improvement. This suggests that the W-2135's higher base clock of 3.70 GHz compensates for its core deficit, at least in these Cinebench workloads.

The W-1290TE's wins are more meaningful in the context of power consumption. Its 35 W TDP is a quarter of the W-2135's 140 W TDP. For environments where thermal output and energy draw are constrained, the W-1290TE delivers essentially identical performance with dramatically lower power requirements. The W-2135's 140 W TDP places it in a different thermal class, requiring more substantial cooling and power delivery infrastructure.

The W-2135 does not win any benchmark category outright, but it holds its ground in single-core performance. Both processors achieve identical single-core scores in R15 (173) and nearly identical scores in R20 (724 vs 723) and R23 (1724 vs 1723). For single-threaded applications, the W-2135 is just as capable as the W-1290TE, despite its lower core count. The W-2135 also offers advantages in platform connectivity, with 48 PCIe Gen 3 lanes versus the W-1290TE's 16 lanes, and quad-channel memory support versus dual-channel. These platform-level features do not appear in the Cinebench results but matter for I/O-intensive workloads.

Q: Do they support ECC memory?

A: Both processors support ECC memory. The W-1290TE and W-2135 are both marked as having ECC memory support, consistent with their workstation market segment.

Specification Differences

The two processors differ substantially in their core specifications. The W-1290TE has 10 cores and 20 threads, while the W-2135 has 6 cores and 12 threads. The base clocks diverge significantly: the W-1290TE runs at 1.80 GHz, while the W-2135 runs at 3.70 GHz. Both share the same 4.50 GHz boost clock. The TDP difference is stark, with the W-1290TE rated at 35 W and the W-2135 at 140 W.

The cache configurations also differ. The W-1290TE has 256 KB of L2 cache per core and 20 MB of shared L3 cache. The W-2135 has 1 MB of L2 cache per core and 8.25 MB of shared L3 cache. This means the W-2135 has a larger per-core L2 allocation but significantly less total L3 cache. The W-1290TE's die size is 206 mm², while the W-2135's die is 484 mm², reflecting the different physical layouts.

Memory support differs in bus width. The W-1290TE uses dual-channel memory with 46.9 GB/s bandwidth, while the W-2135 uses quad-channel memory with 85.3 GB/s bandwidth. PCIe connectivity also differs: the W-1290TE provides 16 PCIe Gen 3 lanes, while the W-2135 provides 48 PCIe Gen 3 lanes. The W-1290TE includes integrated Intel UHD Graphics P630, while the W-2135 has no integrated graphics. The sockets are incompatible, with the W-1290TE using Intel Socket 1200 and the W-2135 using Intel Socket 2066. The launch MSRP for the W-1290TE is $552, while the W-2135 launched at $835. The W-1290TE was released in 2020 and remains active in production, while the W-2135 was released in 2017 and is now end-of-life.

Architecture Differences

The architectural divide is significant. The W-1290TE is built on the Comet Lake architecture, a refinement of Intel's 14 nm process. The W-2135 uses the Skylake architecture, specifically the Skylake-W variant, also on a 14 nm process. Both processors are manufactured by Intel on the same 14 nm node, but they represent different design generations. The W-1290TE is part of the Xeon Comet Lake generation, while the W-2135 belongs to the Xeon W Skylake-W generation.

The L1 cache is identical at 64 KB per core for both processors. However, the L2 cache differs in size per core: 256 KB for the W-1290TE versus 1 MB for the W-2135. The L3 cache also differs, with the W-1290TE offering 20 MB shared versus 8.25 MB shared for the W-2135. This means the W-1290TE has more total cache, which can benefit certain workloads that require large working sets.

The integrated graphics situation is a major differentiator. The W-1290TE includes Intel UHD Graphics P630, making it suitable for systems that need display output without a discrete GPU. The W-2135 lacks any integrated graphics, requiring a dedicated graphics card for display. This is a meaningful consideration for workstation builds where GPU compute is not required but a display output is necessary.

The production status and release timing also differ. The W-1290TE was released in May 2020 and is still marked as active, while the W-2135 was released in August 2017 and is now end-of-life. This means the W-1290TE has a longer expected availability window and potentially better long-term support. The part numbers differ as well: SRJFH for the W-1290TE and SR3LN for the W-2135. Neither processor has an unlocked multiplier, so overclocking is not officially supported on either platform.
