Intel Core i7-9700F vs Intel Xeon W-2135 Comparison

Head-to-Head Benchmarks

The recorded data shows a remarkably consistent picture across the entire Cinebench suite. The Intel Xeon W-2135 wins every single head-to-head benchmark against the Intel Core i7-9700F, with margins that barely waver across different workload types. In Cinebench R15 multicore, the Xeon scores 1230 against 1126 for the i7-9700F, a 9.2% advantage. The single-core test in the same version shows the Xeon at 173 versus 158, a 9.5% lead, which is the largest margin recorded in the entire comparison.

Moving to Cinebench R20, the pattern holds almost identically. The Xeon W-2135 scores 5126 in multicore compared to 4693 for the i7-9700F, again a 9.2% difference. In single-core R20, the scores are 723 and 662 respectively, once more a 9.2% gap. The consistency of these deltas suggests the advantage comes from a fundamental architectural or configuration difference rather than workload-specific behavior.

Cinebench R23 repeats the story. The Xeon W-2135 posts 12205 in multicore versus 11176 for the i7-9700F, another 9.2% margin. Single-core R23 shows 1723 against 1577, a 9.3% gap. Across all six recorded comparisons, the Xeon leads by between 9.2% and 9.5%. There are no tests in the database where the Core i7-9700F comes out ahead.

The average benchmark score places the Xeon W-2135 at 3530 with a 55th percentile ranking among all CPUs, while the i7-9700F averages 3464 and sits at the 54th percentile. Despite the Xeon's consistent head-to-head wins, the overall average scores are close; the i7-9700F has additional Geekbench results in its record that are not present for the Xeon, which affects the aggregate comparison. The nearest rivals for the Xeon include the Intel Core i3-12300 at an average score of 3532 with a 0% delta, the Intel Xeon W-1290TE at 3532 with a -0.1% delta, the Intel Core i5-10600K at 3533 with a -0.1% delta, and the Intel Core i3-12300T at 3525 with a 0.2% delta. For the i7-9700F, the closest competitors are the Intel Xeon E-2186G at 3462 with a 0.1% delta, the AMD Ryzen 7 PRO 7730U at 3456 with a 0.2% delta, the AMD Ryzen 5 5600HS at 3447 with a 0.5% delta, and the Intel Core i7-10870H at 3446 with a 0.5% delta.

FAQ

A: The Intel Xeon W-2135 wins all three recorded multicore tests. It leads by 9.2% in Cinebench R15 (1230 vs 1126), Cinebench R20 (5126 vs 4693), and Cinebench R23 (12205 vs 11176).

Q: Does the Core i7-9700F win any benchmark in the comparison?

A: No. The head-to-head data records 6 wins for the Xeon W-2135 and 0 wins for the i7-9700F. The closest the i7 comes is in the average benchmark score, where it trails 3464 to 3530.

Q: How do they compare in single-core performance?

A: The Xeon W-2135 is ahead in every single-core test. The margins are 9.5% in Cinebench R15 (173 vs 158), 9.2% in R20 (723 vs 662), and 9.3% in R23 (1723 vs 1577).

Q: Which CPU has the higher boost clock?

A: The Core i7-9700F has a boost clock of 4.70 GHz compared to 4.50 GHz for the Xeon W-2135. Despite this, the Xeon still records higher single-core scores in all three Cinebench versions.

Q: What is the difference in their percentile rankings?

A: The Xeon W-2135 ranks at the 55th percentile among all CPUs, while the i7-9700F ranks at the 54th percentile. Their average benchmark scores are 3530 and 3464 respectively.

Q: Which processor has more cores?

A: The Core i7-9700F has 8 cores but only 8 threads, while the Xeon W-2135 has 6 cores and 12 threads. The Xeon's hyper-threading appears to compensate for the two-core deficit, as it still wins all multicore tests.

The Verdict

The data points to a clear winner for raw compute performance: the Intel Xeon W-2135. It secures all six head-to-head benchmark wins with margins consistently around 9.2% to 9.5%. Anyone prioritizing maximum Cinebench throughput should choose the Xeon W-2135 without hesitation. The i7-9700F is not without merit, however. It offers 8 physical cores versus 6, a higher boost clock of 4.70 GHz versus 4.50 GHz, and a significantly lower TDP of 65 watts versus 140 watts. The i7-9700F also has a larger shared L3 cache at 12 MB versus 8.25 MB.

The choice depends on priorities. For pure benchmark performance, the Xeon W-2135 is the stronger pick. For lower power consumption in a desktop context, the i7-9700F is the more efficient option. The i7-9700F carries a launch MSRP of $333, while the Xeon W-2135 lists at $835. Neither processor is unlocked for overclocking, and both are end-of-life products.

Specification Differences

The two processors differ across almost every major specification category. The Xeon W-2135 uses 6 cores and 12 threads, while the i7-9700F uses 8 cores and 8 threads. Base clocks are 3.70 GHz for the Xeon and 3.00 GHz for the i7, with boost clocks of 4.50 GHz and 4.70 GHz respectively. The Xeon carries a 140 watt TDP, the i7 just 65 watts. Sockets differ completely: the Xeon uses Intel Socket 2066, the i7 uses Intel Socket 1151.

Memory support shows major divergence. The Xeon W-2135 runs DDR4 in quad-channel configuration with a memory bandwidth of 85.3 GB/s, while the i7-9700F runs DDR4 in dual-channel mode with 42.7 GB/s. The Xeon supports ECC memory, the i7 does not. PCIe lane counts also differ substantially: the Xeon provides Gen 3 with 48 lanes (CPU only), while the i7 provides Gen 3 with 16 lanes (CPU only). The Xeon targets the Server/Workstation market segment, while the i7 is a Desktop part. The Xeon's launch MSRP was $835, the i7's was $333.

Architecture Differences

Both processors are built on Intel's 14 nm process node, but they come from different architectural families. The Xeon W-2135 is based on Skylake, specifically the Skylake-W codename, while the i7-9700F uses Coffee Lake, part of the Coffee Lake Refresh generation. The die sizes reflect the different designs: the Xeon measures 484 mm², while the i7 is significantly smaller at 180.3 mm².

Cache layouts differ in important ways. Both have 64 KB of L1 cache per core. The L2 cache is 1 MB per core on the Xeon but only 256 KB per core on the i7. The shared L3 cache is 8.25 MB on the Xeon versus 12 MB on the i7, which means the i7 has more total L3 despite having fewer resources per core. The Xeon's larger L2 per core likely contributes to its benchmark advantage in single-threaded tests, despite the i7's higher boost clock.

The Xeon W-2135 was released on 2017-08-28, while the i7-9700F launched on 2019-04-22. Both have a production status of end-of-life. Neither processor includes integrated graphics. The Xeon's part number is SR3LN, the i7's is SRG14. The Xeon's quad-channel memory controller and ECC support are hallmarks of its workstation positioning, while the i7's dual-channel configuration and lack of ECC align with mainstream desktop use.

Where Each One Wins

The Xeon W-2135 is the clear choice for workloads that benefit from simultaneous multithreading. Its 12 threads versus the i7's 8 threads give it a decisive edge in all recorded multicore benchmarks, with consistent 9.2% margins in R15, R20, and R23. The larger 1 MB per-core L2 cache and quad-channel memory bandwidth of 85.3 GB/s make it better suited for memory-intensive workstation tasks. The 48 PCIe Gen 3 lanes provide far more expansion headroom for workstation peripherals, storage controllers, or accelerators. ECC memory support is a critical differentiator for users who need error-correcting memory in professional workloads.

The i7-9700F wins on efficiency and physical core count. Its 65 watt TDP makes it far easier to cool and power than the 140 watt Xeon. The 8 physical cores with a 4.70 GHz boost clock give it an edge in scenarios where raw core count matters more than thread count, though the benchmark data does not show this translating into a win in any recorded test. The 12 MB shared L3 cache is larger than the Xeon's 8.25 MB, which could benefit certain cache-sensitive applications. The smaller 180.3 mm² die and dual-channel memory configuration make it a more compact, less demanding platform overall. The Socket 1151 platform is also more common in desktop systems, which may simplify motherboard selection compared to the Socket 2066 workstation platform. For users building a desktop system with modest power delivery and cooling requirements, the i7-9700F is the more practical option, even though the recorded benchmarks favor the Xeon in every measured category.
