Intel Core i7-9700T vs Intel Core i7-9750HF Comparison

The Intel Core i7-9700T and Intel Core i7-9750HF are both 14 nm Coffee Lake parts from the same generation, but they target completely different platforms. The data shows a clear split: the 9750HF dominates in Cinebench workloads, while the 9700T takes the lead in Geekbench. Both sit at the 50th percentile among all CPUs, with an average benchmark score of 2668 for the 9700T and 2662 for the 9750HF. This makes them nearly identical in overall performance, but the way they get there is very different.

Head-to-Head Benchmarks

The most striking result is the Geekbench multicore test, where the Intel Core i7-9700T scores 5503 against the 9750HF’s 4844. That is a 13.6% advantage for the 9700T, and it is the largest delta in the entire comparison. The desktop part also wins in Geekbench singlecore, scoring 1392 versus 1365, a 2% edge. These are the only two benchmarks the 9700T wins out of the eight tested.

Every Cinebench test goes the other way. The Intel Core i7-9750HF wins Cinebench R15 multicore with 876 points versus 839, a 4.2% margin. In R15 singlecore, it scores 123 against 118, a 4.1% lead. The R20 results show the same pattern: 3652 versus 3496 in multicore and 515 versus 493 in singlecore, both at a 4.3% delta. The R23 tests are equally consistent, with the 9750HF posting 8696 in multicore and 1227 in singlecore, while the 9700T manages 8325 and 1175. That is a 4.3% gap in R23 multicore and a 4.2% gap in R23 singlecore.

The overall win count favors the 9750HF, which takes 6 of the 8 benchmarks. However, the magnitude of the 9700T’s Geekbench multicore win is more than three times larger than any single Cinebench margin. Netting out the deltas, the 9750HF’s consistent Cinebench leads are smaller individually but they appear across six tests, giving it the overall edge in synthetic rendering workloads.

Geekbench tends to emphasize memory latency and integer throughput, while Cinebench scales heavily with thread count and sustained clock behavior. The 9700T’s 13.6% win in Geekbench multicore suggests its 8 physical cores handle certain parallel integer tasks better than the 9750HF’s 6 cores with 12 threads. Conversely, the 9750HF’s higher boost clock of 4.50 GHz versus 4.30 GHz likely drives its consistent Cinebench wins, even with fewer physical cores.

Where Each One Wins

The Intel Core i7-9750HF is the pick for Cinebench-style workloads. It wins every single Cinebench test, from R15 through R23, in both single-threaded and multi-threaded modes. The margins are tight, between 4.1% and 4.3%, but they are uniform. This indicates a fundamental clock advantage rather than a core-count effect. The 9750HF’s 4.50 GHz boost clock gives it a sustained edge in short, bursty rendering tasks that do not fully saturate all cores.

The Intel Core i7-9700T owns Geekbench. Its 5503 multicore score is dramatically higher than the 9750HF’s 4844, and its 1392 singlecore score also leads. This makes it the better choice for applications that follow Geekbench’s access patterns, which include encryption, compression, and physics simulation. The 9700T’s 8 physical cores, even without Hyper-Threading, appear to handle these workloads more efficiently than the 9750HF’s 6 cores with 12 threads.

For mixed use, the data points to a split personality. The 9750HF is better for rendering and any Cinebench-like benchmark. The 9700T is better for Geekbench-style integer and memory-bound tasks. Neither is universally faster; the choice depends entirely on the target application. The 9700T’s wins are concentrated but decisive, while the 9750HF’s wins are broad but shallow.

Architecture Differences

Both CPUs share the Coffee Lake architecture, but they are distinct variants. The 9700T is Coffee Lake desktop silicon, while the 9750HF is Coffee Lake-HR, the mobile refresh. Both use the same 14 nm process node from Intel, and both have identical L1 cache at 64 KB per core and L2 cache at 256 KB per core. The L3 cache is also the same: 12 MB shared.

The core configuration is where the architecture diverges. The 9700T has 8 cores and 8 threads, meaning no Hyper-Threading. The 9750HF has 6 cores and 12 threads, meaning each core runs two threads. This is a fundamental design difference. The 9700T relies on raw physical core count, while the 9750HF leans on simultaneous multithreading to fill its pipeline.

The die sizes reflect the different designs. The 9700T has a die size of 180.3 mm², while the 9750HF is smaller at 149 mm². The smaller die suggests the mobile part is more tightly integrated, but the core count difference explains the size gap. The 9700T has two more physical cores, which take up space.

The integrated graphics also differ significantly. The 9700T includes UHD Graphics 630, while the 9750HF has no integrated graphics at all. This is unusual for a mobile chip, but the "HF" suffix indicates a graphics-disabled part. The 9700T can drive a display without a discrete GPU; the 9750HF cannot.

Specification Differences

The most obvious specification difference is the socket. The 9700T uses Intel Socket 1151, a desktop LGA socket. The 9750HF uses Intel BGA 1440, which is a soldered mobile package. This means the 9700T is upgradeable and replaceable, while the 9750HF is permanently attached to its motherboard.

The TDP ratings differ substantially. The 9700T has a 35 W TDP, while the 9750HF is rated at 45 W. This is counterintuitive given the 9700T has more cores, but the desktop part’s lower power target allows for lower sustained clocks under load. The 9750HF’s higher TDP gives it more headroom for boost clocks.

Base and boost clocks are different. The 9700T runs at 2.00 GHz base and 4.30 GHz boost. The 9750HF runs at 2.60 GHz base and 4.50 GHz boost. The 9750HF starts higher and ends higher, which explains its Cinebench wins. The 9700T’s much lower base clock is a direct result of its 35 W TDP.

The PCIe implementation differs. The 9700T offers Gen 3 with 16 lanes from the CPU. The 9750HF lists only Gen 3 without a lane count, suggesting fewer available lanes due to the mobile platform. Memory support is identical: both support DDR4 in dual-channel mode with 42.7 GB/s bandwidth. Neither supports ECC memory.

The market segments are opposite. The 9700T is a desktop chip, and the 9750HF is a mobile chip. Both are end-of-life, released on the same date of 2019-04-22. The 9700T has a launch MSRP of $323, while the 9750HF has no listed launch MSRP. Neither has an unlocked multiplier.

The Verdict

The data shows two equally matched CPUs with opposite strengths. If your workload is Cinebench-heavy, the Intel Core i7-9750HF is the clear winner. It wins every Cinebench test, from R15 to R23, by roughly 4%. Its higher base and boost clocks give it a consistent edge in rendering, and its 12 threads help fill the pipeline despite having only 6 physical cores.

If your workload leans toward Geekbench-style tasks, the Intel Core i7-9700T is the better choice. Its 13.6% multicore lead in Geekbench is the single largest performance gap in this comparison. The 8 physical cores provide a tangible benefit for integer-heavy parallel workloads, and the 2% singlecore win shows it is competitive even at lower clocks.

For a desktop builder, the 9700T offers the practical advantage of a Socket 1151 platform with replaceable parts and integrated graphics. The 9750HF is locked to a BGA 1440 mobile board, which means it is not a drop-in upgrade for any existing system. The 9700T’s 35 W TDP also makes it easier to cool in a compact desktop, while the 9750HF’s 45 W TDP demands more from a laptop cooling solution.

The overall average scores are nearly identical, so the decision comes down to specific applications. Pick the 9750HF for rendering and single-threaded burst tasks. Pick the 9700T for Geekbench-style integer workloads and for a desktop platform with graphics output. Neither CPU is a bad choice; they are simply tuned for different environments. The 9750HF wins more benchmarks, but the 9700T wins the one that matters most for its target market.
