Intel Core i9-9960X vs Intel Xeon D-2775TE Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core i9-9960X wins every single recorded head-to-head test against the Intel Xeon D-2775TE. Across six Cinebench workloads, the i9-9960X holds a consistent advantage of 8.2% to 8.3% in both single-core and multi-core tests. This is not a narrow margin; it is a uniform performance gap that appears in every measured scenario.

In Cinebench R15 multi-core, the i9-9960X scores 2532 against the Xeon D-2775TE's 2338, a delta of 8.3%. The single-core R15 test shows a similar story: 357 versus 330, an 8.2% lead. Moving to Cinebench R20, the i9-9960X posts 10550 multi-core and 1489 single-core, while the Xeon D-2775TE manages 9745 and 1375 respectively. Again, the delta is exactly 8.3% for both. Cinebench R23 confirms the pattern: 25120 multi-core versus 23204, and 3546 single-core versus 3275, each with an 8.3% gap.

The consistency of these deltas across all tests is notable. It suggests a fundamental performance advantage that scales uniformly, rather than a workload-specific quirk. The i9-9960X's higher boost clock of 4.50 GHz compared to the Xeon's 3.10 GHz likely drives much of this gap, especially in single-threaded tasks where clock speed is the dominant factor.

Looking beyond the head-to-head, the two CPUs occupy similar positions in the broader database. The i9-9960X sits at the 63rd percentile among all CPUs, with an average benchmark score of 6938. The Xeon D-2775TE is at the 62nd percentile, averaging 6711. The nearest rivals for the i9-9960X include the AMD Ryzen 3 3200G (average 6931, delta 0.1%), the Intel Pentium Gold G6400 (average 6969, delta -0.4%), and the Intel Core i5-3470 (average 6906, delta 0.5%). For the Xeon D-2775TE, the closest comparators are the Intel Xeon Gold 5317 (average 6710, delta 0%), the AMD EPYC 72F3 (average 6700, delta 0.2%), and the AMD Ryzen Threadripper 2970WX (average 6760, delta -0.7%).

What these figures reveal is that the i9-9960X, despite being an older desktop part, edges out its newer server-focused counterpart in raw compute. The 227-point gap in average benchmark score (6938 versus 6711) is modest but consistent. The i9-9960X even holds a slight edge over the Intel Xeon W-2195, a workstation processor, with a delta of 0.7% in its favor.

Architecture Differences

The two processors come from different architectural eras and target different market segments. The i9-9960X is built on Intel's 14 nm Skylake-X architecture, codenamed Skylake, and belongs to the Core i9 X-Series 9th Gen lineup. It is a desktop part, released on October 18, 2018, and is now end-of-life. The Xeon D-2775TE, in contrast, uses the 10 nm Ice Lake architecture, codenamed Ice Lake-D, and belongs to the Xeon D (Ice Lake-D) generation. It is a server/workstation processor, released on February 23, 2022, and remains active in production.

The die size differs substantially: the i9-9960X has a die size of 484 mm², while the Xeon D-2775TE's die size is not recorded in the database. The process node difference (14 nm versus 10 nm) explains much of the efficiency gap between them. The Xeon D-2775TE achieves its 100 W TDP despite running 16 cores, while the i9-9960X consumes 165 W at the same core count.

Cache hierarchies also differ. The i9-9960X provides 64 KB of L1 per core, 1 MB of L2 per core, and 22 MB of shared L3. The Xeon D-2775TE has larger per-core allocations: 80 KB of L1, 1.25 MB of L2, and 25 MB of shared L3. This gives the Xeon a total cache advantage that may help in certain server workloads where data reuse is high.

PCIe support is another differentiator. The i9-9960X offers PCIe Gen 3 with 44 lanes (CPU only), while the Xeon D-2775TE provides PCIe Gen 4 with 32 lanes. The newer generation standard on the Xeon allows for higher bandwidth per lane, but the i9-9960X has more total lanes available.

The socket types are completely incompatible. The i9-9960X uses Intel Socket 2066, while the Xeon D-2775TE is soldered to Intel BGA 2579. This means the i9-9960X can be upgraded or replaced on a compatible motherboard, while the Xeon D-2775TE is typically integrated into a fixed server platform.

Specification Differences

The two processors share the same core count (16) and thread count (32), but nearly every other specification diverges. The i9-9960X has a base clock of 3.10 GHz and a boost clock of 4.50 GHz. The Xeon D-2775TE has a base clock of 2000.00 MHz (2.00 GHz) and a boost clock of 3.10 GHz. The desktop part clocks significantly higher, which explains its benchmark advantage.

Thermal design power is a major difference: the i9-9960X has a TDP of 165 W, while the Xeon D-2775TE is rated at 100 W. The Xeon's lower TDP reflects its server-focused design and newer 10 nm process. The i9-9960X requires more power but delivers higher peak performance.

Memory bandwidth favors the Xeon: 93.9 GB/s versus 85.3 GB/s. Both use quad-channel DDR4, but the Xeon's implementation is more efficient. ECC memory support is exclusive to the Xeon D-2775TE, a critical feature for server reliability.

The production status differs: the i9-9960X is end-of-life, while the Xeon D-2775TE is active. Release dates are also distinct, with the i9-9960X launching in October 2018 and the Xeon D-2775TE in February 2022. The i9-9960X has an unlocked multiplier for overclocking, while the Xeon D-2775TE is locked.

The launch MSRP for the i9-9960X is $1684. The Xeon D-2775TE has a launch MSRP of $1751.

The Verdict

The benchmark data clearly favors the Intel Core i9-9960X for raw performance. It wins every head-to-head test with a consistent 8.2% to 8.3% margin. Its higher clock speeds, reaching 4.50 GHz boost, give it a decisive edge in both single-threaded and multi-threaded workloads. The i9-9960X is the better choice for anyone prioritizing maximum compute throughput, whether in rendering, encoding, or general productivity tasks.

However, the Xeon D-2775TE is not without its merits. It delivers 93.9 GB/s of memory bandwidth, higher than the i9-9960X's 85.3 GB/s, which can benefit memory-intensive server workloads. It also supports ECC memory, essential for data integrity in server environments. Its 100 W TDP makes it significantly more power-efficient per core, and its 10 nm Ice Lake architecture brings newer instruction set features.

The choice depends on the use case. For a desktop workstation where performance is the sole criterion, the i9-9960X is the clear winner. For a server deployment where reliability, memory bandwidth, and power efficiency matter more than peak compute, the Xeon D-2775TE is the appropriate selection. The data does not suggest the Xeon can match the i9-9960X in raw speed, but it offers a different set of strengths tailored to a different environment.

Where Each One Wins

Intel Core i9-9960X: Wins in every recorded benchmark category. Its single-core performance (357 in R15, 1489 in R20, 3546 in R23) is superior, making it better for lightly threaded applications. Its multi-core scores (2532 in R15, 10550 in R20, 25120 in R23) also top the Xeon, favoring heavily threaded workloads. The unlocked multiplier and 44 PCIe Gen 3 lanes make it a flexible desktop platform for enthusiasts and workstation users.

Intel Xeon D-2775TE: Wins in efficiency and server-oriented features. Its 100 W TDP versus the i9-9960X's 165 W means it generates less heat and consumes less power for similar core counts. Its 93.9 GB/s memory bandwidth exceeds the i9-9960X by 8.6 GB/s, which can improve performance in memory-bound server tasks. ECC memory support is a decisive advantage for mission-critical applications. PCIe Gen 4 support, while fewer lanes (32 versus 44), offers higher per-lane bandwidth for modern accelerators and networking. The Xeon is the better choice for always-on server environments where stability and data integrity are paramount.
