Intel Core i9-10980HK vs Intel Xeon E5-2678 v3 Comparison

Where Each One Wins

The Intel Core i9-10980HK sweeps every recorded benchmark in this comparison. Across six Cinebench tests, it takes the win in all of them, which makes the use-case split straightforward: the Core i9-10980HK is the faster part in both single-threaded and multi-threaded workloads, though the margins are consistently narrow.

The Core i9-10980HK leads by 2.7% in Cinebench R15 multicore, R20 multicore, and R23 multicore. It also leads by 2.8% in Cinebench R15 singlecore and by 2.7% in both R20 and R23 singlecore tests. These are not transformative gaps; they are small but real performance advantages that hold across every rendering workload recorded in the database.

The Intel Xeon E5-2678 v3 wins nothing here. Its best result, a 1257 score in Cinebench R15 multicore, still trails the Core i9-10980HK's 1291. In singlecore tests, the Xeon's highest mark is 177 in R15, against 182 for the Core i9. The Xeon's 12 cores and 24 threads do not translate into a multicore victory, which speaks to the efficiency of the Core i9's newer architecture and higher clock speeds.

For users deciding between the two, the data points clearly to the Core i9-10980HK for any task that benefits from either single-thread speed or multicore throughput. The Xeon E5-2678 v3 retains its role as a server or workstation part with ECC memory support and a quad-channel memory bus, but in raw Cinebench performance, the mobile Core i9 part is ahead across the board.

Architecture Differences

The two processors come from different Intel generations and target different market segments. The Core i9-10980HK is a Comet Lake-H part built on the 14 nm process, while the Xeon E5-2678 v3 is Haswell-EP on the 22 nm node. That process gap alone explains much of the performance delta: the newer 14 nm design allows higher clocks with lower power draw.

Core counts differ significantly. The Xeon E5-2678 v3 packs 12 cores and 24 threads, while the Core i9-10980HK has 8 cores and 16 threads. Despite having fewer cores, the Core i9 wins all multicore tests, thanks to a boost clock of 5.30 GHz versus the Xeon's 3.30 GHz. The base clocks are closer: 2.40 GHz for the Core i9 and 2.50 GHz for the Xeon.

Cache configurations also diverge. The Core i9-10980HK has 16 MB of shared L3 cache, while the Xeon E5-2678 v3 has 30 MB of shared L3. Both have 64 KB L1 and 256 KB L2 per core. The larger L3 on the Xeon does not compensate for its lower clock ceiling in these benchmarks.

The memory systems reflect their intended platforms. The Core i9 supports DDR4 only, with no ECC support. The Xeon supports both DDR3 and DDR4, has a quad-channel memory bus, and offers ECC memory capability. The Xeon also provides 40 PCIe Gen 3 lanes from the CPU, versus 16 lanes for the Core i9. The Core i9 includes integrated UHD Graphics; the Xeon has no integrated graphics.

Socket types differ completely: the Core i9 uses Intel BGA 1440, a mobile socket, while the Xeon uses Intel Socket 2011-3, a server/workstation platform. The Core i9 has an unlocked multiplier; the Xeon does not. The Core i9 was released in April 2020 with a launch MSRP of $643, while the Xeon's release date is not recorded in the database.

Head-to-Head Benchmarks

The closest race is in Cinebench R15 multicore, where the Core i9-10980HK scores 1291 against the Xeon E5-2678 v3's 1257, a 2.7% advantage. This is notable because the Xeon has 50% more cores and 50% more threads, yet the Core i9 still comes out ahead. The higher boost clock of the Core i9, 5.30 GHz versus 3.30 GHz, appears to be the decisive factor.

Cinebench R15 singlecore shows a 2.8% lead for the Core i9: 182 versus 177. This is the largest percentage gap in any test, reflecting the Core i9's superior single-thread clock speed and newer architecture.

In Cinebench R20, the multicore score for the Core i9 is 5381, while the Xeon posts 5239, a 2.7% difference. The singlecore R20 result is 759 versus 739, also a 2.7% gap. These results mirror the R15 pattern almost exactly, suggesting a consistent performance ratio between the two parts across Cinebench versions.

Cinebench R23 multicore has the Core i9 at 12812 and the Xeon at 12474, again a 2.7% lead. The singlecore R23 result is 1808 versus 1761, a 2.7% gap. Every head-to-head benchmark in the database shows the same winner and nearly the same percentage margin, which indicates that the Core i9's advantage is stable rather than workload-specific.

The average benchmark score in the database puts the Core i9 at 3706, with a 56th percentile ranking among all CPUs. The Xeon averages 3608, at the 55th percentile. The Core i9's nearest rivals include the Intel Xeon E-2434 at 3709 (-0.1%), the Intel Core i5-11260H at 3721 (-0.4%), and the AMD Ryzen 5 PRO 4650GE at 3732 (-0.7%). The Xeon's nearest rivals are the Intel Xeon E-2286G at 3610 (-0.1%) and the AMD Ryzen 7 PRO 1700 at 3613 (-0.1%).
