Intel Core i7-10870H vs Intel Xeon E-2246G Comparison

The Verdict

The benchmark data makes the separation clear. The Intel Core i7-10870H wins 7 of 8 head-to-head comparisons, while the Intel Xeon E-2246G takes only a single win. For anyone prioritizing raw multi-threaded throughput, the i7-10870H is the stronger choice, particularly in Geekbench multi-core where it leads by 18.6%. However, the Xeon E-2246G holds a decisive advantage in Geekbench single-core performance, leading by 11.8%. The Xeon also brings server-class features such as ECC memory support and a workstation market segment, which the mobile i7 lacks. The data suggests the Xeon suits single-thread-focused workstation tasks requiring error-correcting memory, while the i7-10870H is better suited for general multi-threaded workloads on mobile platforms.

The i7-10870H's 8 cores and 16 threads against the Xeon's 6 cores and 12 threads explain its multi-core edge. Across Cinebench R15, R20, and R23 multi-core tests, the i7 wins by a narrow 1.1% margin each time. That consistency is notable: the i7 does not blow out the Xeon in Cinebench, but it wins every iteration. The Geekbench multi-core gap is far larger at 18.6%, indicating the i7's advantage scales significantly in that specific workload. Conversely, the Xeon's Geekbench single-core score of 1613 versus the i7's 1443 shows a clear single-thread preference for the Xeon.

The i7-10870H also posts the higher boost clock at 5.00 GHz versus 4.80 GHz on the Xeon, yet the Xeon still wins single-core Geekbench. This implies architectural efficiency or memory subsystem advantages for the Xeon in that test. The i7's 16 MB shared L3 cache versus the Xeon's 12 MB shared L3 provides another reason for its multi-core strength. The i7 is also an active production part, while the Xeon is end-of-life, which matters for long-term availability.

Architecture Differences

The two processors come from different Intel families despite sharing the same 14 nm process node and Intel foundry. The Xeon E-2246G is based on Coffee Lake architecture with the Coffee Lake-S WS codename, part of the Xeon E-2200 series. The Core i7-10870H uses Comet Lake architecture with the Comet Lake-H codename, belonging to the Core 10th Gen series. The Xeon's generation is listed as "Xeon E (Coffee Lake)", while the i7's generation is "Core i7 (Comet Lake-H)".

The socket situation differs completely. The Xeon E-2246G fits Intel Socket 1151, a desktop/workstation socket. The Core i7-10870H uses Intel BGA 1440, which is a mobile soldered socket. This means the Xeon can be installed in a standard socketed motherboard, while the i7 is permanently attached to a laptop or mobile board.

The market segments reflect their intended roles. The Xeon is designated as a Server/Workstation part, while the i7 is classified as Mobile. This aligns with the Xeon's ECC memory support and the i7's lack thereof. The Xeon also features HD Graphics P630 as integrated graphics, whereas the i7 has UHD Graphics (without a specific model number in the data).

Both processors share the same PCIe configuration: Gen 3 with 16 lanes (CPU only). Both have the same L1 cache at 64 KB per core and L2 cache at 256 KB per core. The L3 cache differs, with the Xeon offering 12 MB shared and the i7 offering 16 MB shared. The Xeon's die size is 154 mm², while the i7's die size is not recorded.

The release dates are roughly a year and a half apart. The Xeon launched on 2019-05-28, while the i7 launched on 2020-09-16. The Xeon has a launch MSRP of $311, and the i7 has no recorded launch MSRP. Neither processor has an unlocked multiplier.

Specification Differences

The core and thread counts are the primary specification split. The Xeon E-2246G has 6 cores and 12 threads. The Core i7-10870H has 8 cores and 16 threads. This gives the i7 a 33% advantage in core count and a 33% advantage in thread count.

Base clocks differ substantially. The Xeon runs at a 3.60 GHz base clock, while the i7 runs at a 2.20 GHz base clock. Boost clocks are closer, with the Xeon at 4.80 GHz and the i7 at 5.00 GHz. The i7's higher boost clock helps it compete in single-thread tests, though the Xeon still wins Geekbench single-core.

Thermal design power (TDP) shows a major divergence. The Xeon is rated at 80 W, while the i7 is rated at 45 W. This makes the i7 a significantly lower-power part, suitable for mobile chassis, while the Xeon demands more cooling for desktop or workstation use.

Memory specifications are unevenly documented. Both support DDR4 memory. The Xeon specifies a dual-channel memory bus and a memory bandwidth of 42.7 GB/s. The i7's memory bus and memory bandwidth are not recorded in the database. ECC memory support is exclusive to the Xeon.

The Xeon's L3 cache is 12 MB shared. The i7's L3 cache is 16 MB shared. Both have identical L1 and L2 caches at 64 KB and 256 KB per core, respectively.

The Xeon has a die size of 154 mm², while the i7's die size is not recorded. The Xeon's part number is SRF7G, and the i7's part number is SRK3Y.

Head-to-Head Benchmarks

The head-to-head results show a consistent pattern. In Cinebench R15 multi-core, the i7 scores 1194 against the Xeon's 1181, a 1.1% difference favoring the i7. In Cinebench R15 single-core, the i7 scores 168 versus 166, a 1.2% difference. The i7 wins again in Cinebench R20 multi-core with 4977 versus 4922, and in R20 single-core with 702 versus 694, both at 1.1% deltas.

Cinebench R23 repeats the same story. The i7 wins multi-core with 11852 versus 11720, and single-core with 1673 versus 1654, each at a 1.1% margin. Across all six Cinebench tests, the i7's advantage is remarkably uniform, hovering near 1.1% to 1.2%. This indicates that in Cinebench workloads, the two processors are nearly equivalent, with the i7 holding a slight but consistent edge.

The Geekbench results break the pattern. In multi-core, the i7 scores 7357 versus the Xeon's 5988, an 18.6% landslide for the i7. This is the largest delta in the entire comparison. In single-core, the roles reverse dramatically: the Xeon scores 1613 versus 1443, an 11.8% win for the Xeon.

The Geekbench multi-core result aligns with the i7's additional 2 cores and 4 threads. However, the single-core result contradicts the i7's higher boost clock. The Xeon's 3.60 GHz base clock, which is much higher than the i7's 2.20 GHz, likely contributes to its single-core advantage. The Xeon also has a smaller L3 cache (12 MB versus 16 MB), but that does not appear to hurt it in this specific test.

The overall benchmark counts are decisive. The i7 wins 7 benchmarks, while the Xeon wins 1. The average benchmark score for the Xeon is 3492, and for the i7 it is 3446. Interestingly, the Xeon has a slightly higher average score despite losing more benchmarks, because its single-core Geekbench win and its narrow Cinebench losses keep its average competitive. The percentile rankings are close: the Xeon sits at the 55th percentile of all CPUs, while the i7 sits at the 54th percentile.

The nearest rivals also differ. The Xeon's closest competitors include the Intel Xeon E5-1680 v4 (avg score 3494, delta 0%), Intel Xeon D-1732TE (3486, 0.2%), Intel Core i9-9900T (3499, -0.2%), and Intel Core i9-10900TE (3484, 0.2%). The i7's nearest rivals include the AMD Ryzen 5 5600HS (3447, 0%), AMD Ryzen 5 4600HS (3444, 0.1%), Intel Core i7-5960X (3442, 0.1%), and AMD Ryzen 3 PRO 5350G (3441, 0.1%). These rivalries place both chips in the same general performance tier, despite the different benchmark outcomes.

Where Each One Wins

The Intel Core i7-10870H wins in every Cinebench test and in Geekbench multi-core. Its 8-core, 16-thread configuration with a 5.00 GHz boost clock and 16 MB L3 cache makes it the clear choice for multi-threaded rendering, video encoding, and any CPU-bound workload that scales across threads. The 18.6% Geekbench multi-core lead over the Xeon is its strongest case. The i7 also consumes less power at 45 W TDP versus 80 W, making it more suitable for mobile systems where thermal and power constraints matter.

The Intel Xeon E-2246G wins only Geekbench single-core, but it wins that test decisively at 11.8% over the i7. Its 3.60 GHz base clock and 4.80 GHz boost clock, combined with 6 cores and 12 threads, deliver superior single-thread performance in that benchmark. The Xeon also offers ECC memory support, which the i7 lacks entirely. For workstation users who require error-correcting memory and prioritize single-thread latency, the Xeon is the appropriate pick. Its 80 W TDP is higher, but that is acceptable in a desktop or workstation chassis with adequate cooling.

The data does not support the Xeon as a multi-core champion. Its Cinebench scores trail the i7 by roughly 1.1% across every iteration, and its Geekbench multi-core deficit is 18.6%. The i7's wins are more numerous and more consistent. The Xeon's single victory, while substantial, is isolated to one benchmark.

For use-case splits, the i7-10870H is the better choice for mobile workstations or laptops where multi-threaded performance is the priority, given its active production status and 45 W TDP. The Xeon E-2246G is better for stationary workstation builds where ECC memory is mandatory and single-core Geekbench performance matters more than multi-thread scaling. The Xeon's end-of-life status is a consideration, but its server-class memory support gives it a niche the i7 cannot fill.
