Intel Core i7-1365UE vs Intel Core i7-8700T Comparison

The Intel Core i7-8700T and Intel Core i7-1365UE occupy opposite ends of the hardware spectrum, yet benchmark results show they land in a similar performance class. The 8700T is a 35W desktop part from the Coffee Lake era, while the 1365UE is a 15W mobile processor built on Raptor Lake. Despite the generational gap and differing design goals, their average benchmark scores are remarkably close—2701 for the 8700T versus 2677 for the 1365UE. The data reveals a nuanced picture: the newer mobile chip wins every single head-to-head benchmark, but the margins are consistently narrow, hovering around 6%. This comparison investigates what those margins mean for real-world usage and why a decade-old desktop chip can still hold its own against a modern low-power mobile part.

Where Each One Wins

The benchmark data shows a clean sweep for the Intel Core i7-1365UE across all six head-to-head tests, but the victory margins tell a story of incremental gains rather than generational leaps. In multi-core workloads, the 1365UE consistently outperforms the 8700T by roughly 6%. For instance, in Cinebench R23 multi-core, the 1365UE scores 9257 against the 8700T’s 8698, a difference of 559 points. The single-core results follow the same pattern: the 1365UE leads in Cinebench R23 single-core with 1306 versus 1228 for the 8700T.

The 1365UE’s wins are consistent across all Cinebench versions—R15, R20, and R23—in both single-core and multi-core tests. This suggests the 1365UE holds a structural advantage in raw compute efficiency. However, the 8700T is not without merit. Its average benchmark score of 2701 is actually 24 points higher than the 1365UE’s 2677, a quirk that arises because the 8700T has additional Geekbench results (multi-core 5168 and single-core 1343) that are not available for the 1365UE. Those Geekbench scores boost the 8700T’s average, indicating that in certain workloads, the older chip can compete favorably. The 8700T also matches the 1365UE’s 50th percentile ranking among all CPUs, meaning both processors sit at the median of the database.

For use-case splits, the data suggests the 1365UE is the better choice for sustained multi-threaded tasks like video rendering or code compilation, where its 6% lead in Cinebench R20 multi-core (3887 vs 3653) translates to shorter completion times. Conversely, the 8700T’s Geekbench scores imply it may hold its own in memory-sensitive or mixed workloads, though the lack of comparable Geekbench data for the 1365UE makes this a tentative conclusion. The 1365UE also wins on power efficiency—its 15W TDP is less than half the 8700T’s 35W—making it the clear pick for battery-powered or thermally constrained environments.

Architecture Differences

The two processors represent distinct architectural philosophies. The 8700T uses Intel’s Coffee Lake architecture on a 14nm process node, while the 1365UE employs Raptor Lake on a 10nm node. This process shrink is a primary driver of the 1365UE’s efficiency gains, allowing it to deliver higher performance at a much lower TDP. The core counts differ significantly: the 8700T has 6 cores and 12 threads, while the 1365UE packs 10 cores and 12 threads. The 1365UE’s extra cores are likely efficiency-oriented, which explains why its multi-core advantage is only 6% despite having 67% more cores—the additional cores probably run at lower clocks.

Clock speeds tell a similar story. The 8700T has a base clock of 2.40 GHz and a boost clock of 4.00 GHz. The 1365UE’s base clock is listed as 1700.00 MHz (1.70 GHz), but its boost clock reaches 4.90 GHz. This wide boost range indicates a design that conserves power at idle but can surge to high frequencies when needed. The 1365UE’s cache hierarchy also differs: it has 80 KB of L1 cache per core and 1.25 MB of L2 per core, compared to the 8700T’s 64 KB and 256 KB respectively. Both share 12 MB of L3 cache, so the larger per-core L1 and L2 caches on the 1365UE may improve data locality and reduce latency.

Memory support diverges as well. The 8700T only supports DDR4, while the 1365UE supports both DDR4 and DDR5. Both use dual-channel memory, but the 8700T has a listed memory bandwidth of 42.7 GB/s, a figure not provided for the 1365UE. PCIe capabilities differ: the 8700T offers Gen 3 with 16 lanes, while the 1365UE has Gen 4 with 8 lanes. The 1365UE’s newer PCIe generation doubles the bandwidth per lane, which could benefit fast SSDs or external GPUs despite fewer total lanes. Integrated graphics also differ, with the 8700T featuring UHD Graphics 630 and the 1365UE using Iris Xe Graphics 80EU, a more capable iGPU for media tasks.

Specification Differences

The specification sheets reveal several key differences between the two chips. The 8700T is a desktop processor on Intel Socket 1151, while the 1365UE is a mobile chip on Intel BGA 1744. The 8700T uses the Coffee Lake architecture on a 14nm process, while the 1365UE uses Raptor Lake on a 10nm process. The 8700T has 6 cores and 12 threads; the 1365UE has 10 cores and 12 threads. Base clocks differ significantly: 2.40 GHz for the 8700T versus 1.70 GHz for the 1365UE, but boost clocks are 4.00 GHz and 4.90 GHz respectively. TDP is a major divergence: 35W for the 8700T versus 15W for the 1365UE.

Cache sizes differ per core: the 8700T has 64 KB L1 and 256 KB L2, while the 1365UE has 80 KB L1 and 1.25 MB L2. Both have 12 MB of shared L3 cache. Memory support varies, with the 8700T limited to DDR4 and the 1365UE accepting DDR4 and DDR5. The 8700T lists a memory bandwidth of 42.7 GB/s; the 1365UE has no bandwidth figure. PCIe capabilities differ: Gen 3 with 16 lanes for the 8700T, Gen 4 with 8 lanes for the 1365UE. Integrated graphics differ as well—UHD Graphics 630 for the 8700T versus Iris Xe Graphics 80EU for the 1365UE. The 8700T is marked as end-of-life with a release date in April 2018, while the 1365UE is active and was released in January 2023.

Head-to-Head Benchmarks

The head-to-head results are consistent across all six Cinebench tests, with the 1365UE winning each by approximately 6%. In Cinebench R15 multi-core, the 1365UE scores 932 versus the 8700T’s 876, a delta of -6%. The single-core R15 test shows a similar margin: 131 for the 1365UE versus 123 for the 8700T, a -6.1% difference. Moving to Cinebench R20, the multi-core test has the 1365UE at 3887 and the 8700T at 3653, again a -6% delta. The R20 single-core test shows 548 for the 1365UE and 515 for the 8700T, matching the -6% pattern.

Cinebench R23 results continue the trend. In multi-core, the 1365UE achieves 9257 against the 8700T’s 8698, a -6% difference. The single-core R23 test shows 1306 for the 1365UE and 1228 for the 8700T, also -6%. This uniformity across all tests suggests the 1365UE’s advantage is not workload-specific but rather a consistent performance uplift. The 1365UE’s higher boost clock (4.90 GHz vs 4.00 GHz) likely contributes to the single-core wins, while the combination of more cores and newer architecture drives the multi-core gains. The 8700T’s best showing is in the R15 single-core test, where the 123-point score trails by only 8 points, the smallest absolute margin of any test.

The Verdict

The data presents a clear but nuanced verdict. For users prioritizing raw performance in multi-threaded and single-threaded workloads, the Intel Core i7-1365UE is the superior choice—it wins every head-to-head benchmark by about 6%, delivering 9257 in Cinebench R23 multi-core versus the 8700T’s 8698. The 1365UE also achieves this with a 15W TDP, making it dramatically more power-efficient than the 8700T’s 35W. For mobile or compact systems where thermal headroom is limited, the 1365UE’s combination of lower power draw and higher performance makes it the obvious pick.

However, the 8700T should not be dismissed. Its average benchmark score of 2701 is actually higher, driven by Geekbench results that show strong performance (5168 multi-core, 1343 single-core). For desktop users who already have an LGA 1151 system, the 8700T remains a capable processor, especially since it supports DDR4 memory and offers 16 PCIe Gen 3 lanes—more lanes than the 1365UE’s 8 Gen 4 lanes. The 8700T also carries a 50th percentile ranking, exactly matching the 1365UE, indicating that both processors sit at the median of all CPUs in the database. The choice ultimately depends on the platform: the 1365UE wins on performance and efficiency for new mobile builds, while the 8700T offers a viable upgrade path for existing desktop systems, albeit with a higher power draw and older architecture.
