Intel Core i5-9500F vs Intel Core i9-8950HK Comparison

The Intel Core i5-9500F and Intel Core i9-8950HK are both six-core Coffee Lake parts, but they are built for entirely different platforms and deliver surprisingly divergent results depending on the benchmark. The data shows that the desktop i5-9500F wins decisively in Geekbench tests, while the mobile i9-8950HK edges ahead across the entire Cinebench suite. This split is a direct consequence of their architectural and market positioning, making the choice between them less about raw capability and more about the specific workload.

Architecture Differences

Both processors share the same 14 nm process node and Intel's Coffee Lake architecture, with the i5-9500F using the Coffee Lake refresh generation and the i9-8950HK using the Coffee Lake-H variant. The most fundamental difference is in threading: the i5-9500F is a 6-core/6-thread part, while the i9-8950HK doubles the thread count to 12 via Hyper-Threading. This gives the mobile chip a theoretical multithreading advantage, yet the benchmark results show that advantage is not always realized.

The i9-8950HK also has a higher boost clock of 4.70 GHz compared to the i5-9500F's 4.40 GHz, with a lower base clock of 2.90 GHz versus 3.00 GHz. The i9-8950HK carries a 95 W TDP versus the i5-9500F's 65 W, reflecting its mobile, performance-oriented design. Cache allocation differs as well: the i9-8950HK has 12 MB of shared L3 cache, while the i5-9500F has 9 MB. Both have identical per-core L1 (64 KB) and L2 (256 KB) caches.

Connectivity and form factor are starkly different. The i5-9500F uses Intel Socket 1151 and is a desktop part, supporting DDR4 memory with dual-channel bandwidth of 42.7 GB/s and PCIe Gen 3 with 16 CPU lanes. The i9-8950HK is a mobile BGA 1440 chip with no listed memory bandwidth or PCIe lane data, but it includes integrated UHD 630 graphics, whereas the i5-9500F has no integrated graphics at all. The i9-8950HK also has an unlocked multiplier, making it overclockable, while the i5-9500F is locked. The i9-8950HK has a known die size of 149 mm², while the i5-9500F's die size is not listed.

Head-to-Head Benchmarks

The head-to-head data reveals a clear split: the i9-8950HK wins all six Cinebench tests, but the i5-9500F wins both Geekbench tests by a wide margin. Starting with Cinebench R15 multicore, the i9-8950HK scores 884 against the i5-9500F's 852, a 3.6% lead. The single-core R15 result is closer: 124 versus 120, a 3.2% advantage for the i9-8950HK. This pattern repeats in Cinebench R20, where the i9-8950HK leads multicore 3686 to 3550 (3.7%) and single-core 520 to 501 (3.7%). In Cinebench R23, the i9-8950HK again takes multicore 8777 to 8453 (3.7%) and single-core 1239 to 1193 (3.7%).

The Geekbench results flip the script dramatically. In Geekbench multicore, the i5-9500F scores 5185 versus the i9-8950HK's 4577, a massive 13.3% win for the desktop chip. The single-core Geekbench test shows an even bigger gap: 1504 versus 1318, a 14.1% lead for the i5-9500F. These are not marginal differences; they represent a fundamental performance divergence between the two benchmark suites. The i5-9500F's average benchmark score is 2670, placing it at the 50th percentile of all CPUs, while the i9-8950HK averages 2641, at the 49th percentile.

The i5-9500F's nearest rivals include the Intel Core i7-9700T (average score 2668, within 0.1%) and the Intel Core i7-9750HF (2662, within 0.3%), showing it sits in a tightly contested desktop mid-range. The i9-8950HK's nearest rivals include the Intel Core i7-5820K (2642, exactly 0% delta) and the Core i7-7740X (2648, 0.2% behind), indicating its mobile performance is comparable to older desktop HEDT parts.

FAQ

The Verdict

The data points to a clear conclusion: pick the Intel Core i5-9500F if your workloads resemble Geekbench's mixed integer/floating-point tests, and pick the Intel Core i9-8950HK if your workloads are Cinebench-style rendering. The i5-9500F's 13.3% multicore and 14.1% single-core Geekbench victories are decisive, suggesting better real-world responsiveness in general-purpose computing. The i9-8950HK's Cinebench wins are consistent but small, all under 4%, meaning it offers no significant rendering advantage.

The overall average benchmark scores favor the i5-9500F (2670 versus 2641), but the percentile rankings are nearly identical (50th versus 49th). The i9-8950HK's extra threads and higher boost clock do not translate into a meaningful aggregate lead. For a desktop user, the i5-9500F's lower TDP (65 W versus 95 W) and dual-channel DDR4 support with 42.7 GB/s bandwidth make it the more efficient and capable all-around part. For a mobile user, the i9-8950HK's unlocked multiplier and integrated graphics are the only reasons to choose it, but the benchmark data does not show a performance payoff for those features.

Specification Differences

The two processors differ in several key specification fields. The i5-9500F has 6 cores and 6 threads, while the i9-8950HK has 6 cores and 12 threads. The i5-9500F has a base clock of 3.00 GHz and a boost clock of 4.40 GHz, whereas the i9-8950HK has a base clock of 2.90 GHz and a boost clock of 4.70 GHz. TDP is 65 W for the i5-9500F and 95 W for the i9-8950HK.

The sockets are entirely different: Intel Socket 1151 for the i5-9500F versus Intel BGA 1440 for the i9-8950HK. The i5-9500F uses the Coffee Lake Refresh generation, while the i9-8950HK uses Coffee Lake-H. L3 cache is 9 MB shared on the i5-9500F and 12 MB shared on the i9-8950HK. The i5-9500F supports dual-channel memory with 42.7 GB/s bandwidth and PCIe Gen 3 with 16 lanes; the i9-8950HK has no listed memory bus, bandwidth, or PCIe data. Integrated graphics are absent on the i5-9500F but present as UHD 630 on the i9-8950HK. The i5-9500F's multiplier is locked, while the i9-8950HK's is unlocked. The i9-8950HK has a die size of 149 mm²; the i5-9500F's is not listed.

Where Each One Wins

The Intel Core i5-9500F is the winner for desktop productivity and general computing. Its Geekbench multicore score of 5185 and single-core score of 1504 are far ahead of the i9-8950HK, indicating superior performance in everyday applications, web browsing, office work, and light content creation that relies on quick single-threaded responses. The 65 W TDP also makes it a more thermally manageable choice for standard desktop builds. Users running software that resembles Geekbench's mixed workload — a broad mix of encryption, compression, image processing, and memory tests — will see a clear benefit with the i5-9500F.

The Intel Core i9-8950HK is the winner for mobile rendering workloads and overclocking enthusiasts. Its Cinebench R23 multicore score of 8777 edges out the i5-9500F's 8453, and its single-core score of 1239 beats the i5-9500F's 1193. For users doing sustained 3D rendering or video encoding in Cinebench-style applications, the i9-8950HK provides a slight edge. The unlocked multiplier allows for further tuning, and the integrated UHD 630 graphics provides a display output capability that the i5-9500F lacks entirely. However, these wins are narrow, and the i9-8950HK's performance advantage never exceeds 3.7% in any Cinebench test, making it a marginal choice even in its best-case scenarios.
