Architecture Differences

The Intel Core i7-1185G7E and Intel Core i7-9750HF represent two distinct generations of Intel mobile silicon. The i7-1185G7E is built on Tiger Lake-U architecture with a 10 nm process node from Intel. Its codename is Tiger Lake-U, and it belongs to the Core i7 generation labeled Willow Cove-U. The die size measures 144 mm². This chip uses the Intel BGA 1449 socket.

The Intel Core i7-9750HF comes from the Coffee Lake platform, specifically the Coffee Lake-HR refresh. It uses a 14 nm process node, also produced by Intel. Its die size is slightly larger at 149 mm², and it fits into the Intel BGA 1440 socket.

Core counts differ significantly. The i7-1185G7E provides 4 cores and 8 threads, while the i7-9750HF offers 6 cores and 12 threads. This gives the older chip a 50% advantage in physical core count, which explains its multi-threaded workload results.

Cache hierarchies also diverge. The i7-1185G7E has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, with 12 MB of shared L3 cache. The i7-9750HF has 64 KB L1 per core and 256 KB L2 per core, also with 12 MB of shared L3. The Tiger Lake part uses a much larger per-core L2, while the Coffee Lake chip has a more conventional layout.

The integrated graphics situation is a major architectural split. The i7-1185G7E includes Iris Xe-LP Graphics G7 96EU, making it suitable for systems without a discrete GPU. The i7-9750HF has no integrated graphics, requiring a separate graphics solution in any laptop design.

PCIe support also differs. The i7-1185G7E provides PCIe Gen 4 with 4 lanes from the CPU. The i7-9750HF uses PCIe Gen 3 without specifying lane count in the recorded data.

Memory controller differences follow the generations. The i7-1185G7E supports both DDR4 and LPDDR4X, enabling low-power memory configurations. The i7-9750HF only supports DDR4 and has a recorded memory bandwidth of 42.7 GB/s, a figure not listed for the newer part.

Head-to-Head Benchmarks

The benchmark results create a clear split between Cinebench and Geekbench workloads. Across all six Cinebench tests, the Intel Core i7-9750HF holds the advantage. In Cinebench R15 multi-core, it scores 876 versus 836 for the i7-1185G7E, a 4.6% margin. The single-core R15 test shows 123 against 118, a 4.1% lead.

Cinebench R20 repeats the pattern. Multi-core results are 3652 for the i7-9750HF and 3487 for the i7-1185G7E, a 4.5% gap. Single-core R20 scores are 515 and 492, also a 4.5% difference.

Cinebench R23 continues the trend. The i7-9750HF scores 8696 multi-core and 1227 single-core, while the i7-1185G7E scores 8303 and 1172 respectively. Both margins sit at 4.5%.

The Geekbench results flip the narrative entirely. In multi-core, the i7-1185G7E scores 5459 against 4844 for the i7-9750HF, giving the Tiger Lake chip a 12.7% advantage. The single-core Geekbench test is even more lopsided: 1756 versus 1365, a 28.6% lead for the i7-1185G7E.

The total win count favors the i7-9750HF with 6 wins across the 8 head-to-head benchmarks. The i7-1185G7E takes 2 wins, both in Geekbench.

These results suggest the i7-9750HF benefits from its higher core count in Cinebench's heavily threaded rendering tests. The i7-1185G7E, despite having fewer cores, demonstrates substantially stronger per-core performance in Geekbench, likely due to its newer Willow Cove architecture and higher IPC.

Where Each One Wins

The Intel Core i7-9750HF is the clear choice for sustained multi-threaded rendering workloads. Its six physical cores and twelve threads allow it to outpace the four-core i7-1185G7E in every Cinebench iteration, from R15 through R23. The 4.5% to 4.6% margins are consistent across all three Cinebench versions, indicating the advantage scales predictably with thread count. The higher base clock of 2600 MHz versus 1800 MHz also helps in workloads that do not reach boost frequencies. This processor suits laptops designed around a discrete GPU, since it has no integrated graphics and demands a 45 W thermal envelope.

The Intel Core i7-1185G7E wins in Geekbench, particularly in single-core performance. Its 28.6% single-core advantage over the i7-9750HF is the largest margin in the entire head-to-head comparison. This makes it the better option for bursty, lightly threaded tasks such as application launching, web browsing, and office productivity. The integrated Iris Xe-LP Graphics G7 96EU allows for compact systems without a separate graphics card. Its 15 W TDP also enables thinner, lighter designs with longer battery life potential, and the support for LPDDR4X memory aligns with low-power system configurations.

For users who prioritize Cinebench-style rendering, the i7-9750HF is superior. For those who value Geekbench-style responsiveness and integrated GPU capability, the i7-1185G7E is the better fit. The average benchmark scores reflect this split: the i7-1185G7E averages 2703 points across all tests, while the i7-9750HF averages 2662 points. Both processors sit at the 50th percentile among all CPUs in the database, indicating they are mid-pack performers overall, but their strengths lie in different workload categories.
