CPU Comparison

The Intel Xeon E-2286G and Intel Core i9-9980HK are both 14 nm Coffee Lake parts from 2019, but they target opposite ends of the computing spectrum: one is a socketed workstation processor, the other a soldered mobile flagship. Benchmark data shows they are remarkably close in raw multi-threaded throughput, yet their architectural missions diverge sharply. The Xeon wins 7 of 8 head-to-head tests, while the Core i9 takes a single, significant victory in Geekbench multi-core. This page breaks down where each chip excels, what separates them internally, and how their specification sheets explain the performance picture.

Where Each One Wins

The Xeon E-2286G is the clear winner in rendering and single-threaded workloads. In Cinebench R23 multi-core, it scores 11889 against the i9-9980HK’s 11836, a 0.4% margin. The same 0.4% advantage appears in Cinebench R20 multi-core (4993 vs 4971) and R15 multi-core (1198 vs 1193). Single-core results are nearly identical in Cinebench, 168 vs 168 in R15, 704 vs 701 in R20, 1678 vs 1671 in R23, but the Xeon pulls ahead decisively in Geekbench single-core: 1598 vs 1389, a 15% gap. This makes the E-2286G the better choice for applications that rely on per-thread performance or lightly threaded tasks, as well as for sustained rendering where its higher base clock compensates for fewer cores.

The Core i9-9980HK wins only one head-to-head test, but it is a meaningful one: Geekbench multi-core, where it scores 6687 against the Xeon’s 6651, a 0.5% advantage. This result suggests that in mixed, latency-sensitive workloads, typical of Geekbench’s diverse test suite, the extra two cores and 16 threads of the i9 can overcome the Xeon’s clock speed advantage. However, the margin is slim, and the i9’s victory does not extend to Cinebench’s heavier, more sustained workloads. The i9 is also the only one of the two with an unlocked multiplier, making it the pick for overclocking enthusiasts, though its mobile BGA 1440 socket limits practical cooling solutions.

Architecture Differences

Both processors share the Coffee Lake architecture on Intel’s 14 nm process, but they are distinct die variants. The Xeon E-2286G uses the Coffee Lake-S WS die, measuring 154 mm², while the Core i9-9980HK uses the Coffee Lake-HR die, measuring 149 mm². The core counts differ: the Xeon has 6 cores and 12 threads, while the i9 has 8 cores and 16 threads. The Xeon compensates with a much higher base clock of 4.00 GHz versus the i9’s 2.40 GHz, though the i9’s boost clock of 5.00 GHz slightly exceeds the Xeon’s 4.90 GHz.

Cache configurations also diverge. Both have 64 KB of L1 and 256 KB of L2 per core, but the Xeon’s L3 cache is 12 MB shared, while the i9’s is 16 MB shared. The i9’s larger L3 cache helps its extra cores, but the Xeon’s higher clocks keep it competitive. The Xeon supports ECC memory, a feature absent on the i9, and its integrated graphics is the HD Graphics P630, versus the i9’s UHD 630. The Xeon’s PCIe implementation is specified as Gen 3 with 16 lanes (CPU only), while the i9 lists simply as Gen 3. Power envelopes are dramatically different: the Xeon has a 95 W TDP, while the i9 is a 45 W mobile part, reflecting its intended use in laptops.

The Xeon’s market segment is Server/Workstation, while the i9 is a Mobile processor. The Xeon uses the Intel Socket 1151, allowing it to be installed in desktop motherboards, whereas the i9 is soldered to the board via Intel BGA 1440. Both are end-of-life products, but the Xeon has a launch MSRP of $450, while the i9 has no launch MSRP listed. The Xeon is also marked as having a locked multiplier, while the i9’s multiplier is unlocked.

Specification Differences

The two processors differ in several key specification fields. The Xeon E-2286G has 6 cores and 12 threads, while the i9-9980HK has 8 cores and 16 threads. The Xeon’s base clock is 4.00 GHz, while the i9’s is 2.40 GHz. The boost clock favors the i9: 5.00 GHz versus the Xeon’s 4.90 GHz. TDP is a major differentiator: the Xeon is rated at 95 W, the i9 at 45 W. The Xeon uses Intel Socket 1151, while the i9 uses Intel BGA 1440. The Xeon’s die size is 154 mm², while the i9’s is 149 mm². L3 cache is 12 MB on the Xeon and 16 MB on the i9. The Xeon supports ECC memory, while the i9 does not. The integrated graphics differ: HD Graphics P630 on the Xeon versus UHD 630 on the i9. The market segment is Server/Workstation for the Xeon and Mobile for the i9. The Xeon has a locked multiplier, while the i9’s multiplier is unlocked. The Xeon has a launch MSRP of $450 and part number SRF7C, while the i9 has no launch MSRP and part number SRFD0. The Xeon’s PCIe is specified as Gen 3 with 16 lanes (CPU only), while the i9 lists only Gen 3. Memory bandwidth is identical at 42.7 GB/s for both, as is memory support (DDR4, dual-channel). Process node, foundry, and L1/L2 cache sizes are also identical.

Head-to-Head Benchmarks

The Xeon E-2286G dominates the head-to-head results, winning 7 of 8 tests. The largest single victory is in Geekbench single-core, where the Xeon scores 1598 against the i9-9980HK’s 1389, a 15% delta. This is the standout performance gap between the two chips, driven by the Xeon’s much higher base clock and the i9’s lower single-core efficiency in this particular test. In Cinebench R23 single-core, the Xeon wins again with 1678 versus 1671, a 0.4% margin, and the same 0.4% delta appears in R20 single-core (704 vs 701) and R15 single-core (168 vs 168, a tie in score but awarded to the Xeon).

In multi-core Cinebench tests, the Xeon maintains its lead, albeit by narrow margins. Cinebench R23 multi-core shows 11889 for the Xeon versus 11836 for the i9, a 0.4% delta. Cinebench R20 multi-core follows the same pattern: 4993 vs 4971, 0.4%. Cinebench R15 multi-core is 1198 vs 1193, also 0.4%. These results are striking given that the i9 has two more cores and 4 more threads. The Xeon’s higher base clock (4.00 GHz vs 2.40 GHz) and lower TDP (95 W vs 45 W) suggest it can sustain higher clocks under load, which offsets the i9’s core-count advantage in these rendering workloads.

The i9’s sole victory comes in Geekbench multi-core, where it scores 6687 against the Xeon’s 6651, a 0.5% delta. This is the only test where the i9’s extra cores provide a measurable benefit. The Geekbench suite includes a mix of integer, floating-point, and memory tests, which may better exploit the i9’s 16 threads and larger 16 MB L3 cache. However, the margin is small, and it does not translate to Cinebench, which is more indicative of sustained heavy rendering.

Average benchmark scores place the Xeon at 3610 and the i9 at 3577, a 0.9% difference in the Xeon’s favor. Both processors sit at the 55th percentile among all CPUs, indicating they are mid-pack performers in the broader market. The Xeon’s nearest rivals include the Intel Xeon E5-2678 v3 (3608, +0.1%) and AMD Ryzen 7 2700E (3603, +0.2%), while the i9’s nearest rivals include the AMD Ryzen 7 5825C (3579, -0.1%) and AMD Ryzen 7 2700E (3603, -0.7%). Notably, the i9’s nearest rival list includes the Xeon E-2286G itself, with a delta of -0.9%, confirming the Xeon’s overall advantage in average score. The data paints a clear picture: the Xeon E-2286G is the stronger all-around performer, while the i9-9980HK offers a marginal multi-core win in Geekbench and the flexibility of an unlocked multiplier, but at the cost of a soldered mobile package.
