Intel Core i5-12490F vs Intel Core i7-9700K Comparison

Head-to-Head Benchmarks

The benchmark data is decisively one-sided. The Intel Core i5-12490F wins 15 of the 17 recorded head-to-head tests, with the Intel Core i7-9700K taking only 2. The most dramatic gap appears in data encryption, where the i5-12490F scores 12,018 against the i7-9700K's 4,590, a 161.8% advantage. This is the single largest delta in the entire comparison and highlights the i5's overwhelming strength in cryptographic workloads.

Across the Cinebench suite, the i5-12490F is consistently about 41% faster. In Cinebench R23 multi-core, it scores 17,284 versus 12,238 (41.2% ahead), while in single-core it posts 2,440 against 1,727 (41.3% ahead). The same pattern holds in R20: 7,259 versus 5,139 for multi-core and 1,024 versus 725 for single-core, both with deltas of 41.3% and 41.2% respectively. Cinebench R15 repeats the story at 1,742 versus 1,233 (41.3%) and 245 versus 174 (40.8%).

PassMark tests reinforce the trend. In integer math, the i5-12490F records 60,548 against 41,411, a 46.2% lead. Floating point math shows 47,326 versus 35,498, a 33.3% advantage. The multithread score is 20,202 versus 14,414 (40.2%), and physics simulation results are 1,345 versus 880, a 52.8% lead. Prime number finding shows a 67.3% gap (87 versus 52), and data compression is 14.1% ahead at 237,304 versus 208,062.

The i7-9700K's two wins are narrow. Extended instructions favor it at 18,088 versus 15,993, an 11.6% edge. Random string sorting goes its way at 25,756 versus 23,791, a 7.6% margin. These are the only areas where the older chip demonstrates superiority, and both are specialized workloads rather than general-purpose compute.

Single-thread performance, often a differentiator between generations, heavily favors the i5-12490F. PassMark single-thread shows 3,682 versus 2,865, a 28.5% advantage. This is not a case where the i7's higher boost clock compensates for architectural age; the i5 simply dominates in raw per-core throughput.

Where Each One Wins

The i5-12490F is the clear choice for multithreaded productivity, rendering, and general compute. Its Cinebench results across R15, R20, and R23 show a uniform 41% advantage, making it substantially faster in video encoding, 3D rendering, and batch processing. The PassMark multithread score of 20,202 versus 14,414 confirms this for broader workloads.

For security-related tasks, the i5-12490F is in another league. The 161.8% lead in data encryption suggests AES and similar cryptographic operations run at nearly 2.6 times the speed. Integer-heavy applications also favor it strongly, with the 46.2% gap in integer math indicating strong compiler and execution efficiency.

The i7-9700K retains relevance only in narrow niches. Its 11.6% advantage in extended instructions suggests workloads using AVX2 or similar instruction sets may see a benefit. Random string sorting, a test of memory access patterns and sorting algorithms, shows a 7.6% edge. These are niche scenarios, not mainstream use cases.

For single-threaded responsiveness, the i5-12490F wins clearly. The 28.5% PassMark single-thread lead translates to snappier application launches and better performance in lightly threaded games. Users upgrading from the i7-9700K to the i5-12490F would see improvements in nearly every measurable category.

Architecture Differences

The two processors come from different eras of Intel design. The i5-12490F uses Alder Lake architecture on a 10 nm process node, while the i7-9700K is Coffee Lake on 14 nm. The die size reflects this: 163 mm² for the i5 versus 180.3 mm² for the i7, despite the i5 having fewer physical cores.

Core configuration differs substantially. The i5-12490F has 6 cores and 12 threads, using hyper-threading to double thread count. The i7-9700K has 8 cores but only 8 threads, lacking hyper-threading entirely. This explains the i5's 40%+ multi-core advantage despite having 2 fewer physical cores; simultaneous multi-threading allows better utilization of execution resources.

Cache hierarchies are also different. The i5-12490F features 80 KB L1 cache per core, 1.25 MB L2 per core, and 20 MB shared L3. The i7-9700K has 64 KB L1 per core, 256 KB L2 per core, and only 12 MB shared L3. The larger L3 cache on the i5 contributes to its performance in cache-sensitive workloads.

Clock speeds favor the i7 on paper: 3.60 GHz base and 4.90 GHz boost versus 3.00 GHz base and 4.60 GHz boost for the i5. Yet the i5's newer architecture delivers better instructions-per-clock, overcoming the frequency deficit. The i7's 95 W TDP is also higher than the i5's 65 W, indicating the newer chip achieves more performance with lower power draw.

Platform support differs significantly. The i5-12490F uses Intel Socket 1700 with PCIe Gen 5 and 20 CPU lanes. The i7-9700K uses Intel Socket 1151 with PCIe Gen 3 and 16 lanes. Memory support also diverges: the i5 supports DDR4 and DDR5, while the i7 is limited to DDR4. The i7 includes UHD Graphics 630 integrated graphics, while the i5 has no integrated graphics, requiring a discrete GPU.

The i7-9700K has an unlocked multiplier for overclocking, and its launch MSRP was $385. The i5-12490F has a locked multiplier. The i7 is marked end-of-life in the database, while the i5 remains active. Process node difference (10 nm versus 14 nm) is a fundamental architectural gap that explains most of the performance delta.

Q: Which CPU has better memory support?

A: The i5-12490F supports both DDR4 and DDR5, while the i7-9700K supports only DDR4. However, the i7 has a specified memory bandwidth of 42.7 GB/s, while the i5's bandwidth is not listed in the database.

Q: Are both CPUs in the same performance percentile?

A: Both are at the 74th percentile among all CPUs. Average benchmark scores are 20,802 for the i5-12490F and 20,271 for the i7-9700K, a difference of about 2.6%.

The Verdict

The data is unambiguous: the Intel Core i5-12490F is the superior processor for virtually all workloads. Its 15 wins out of 17 tests, including all Cinebench results and the majority of PassMark tests, establish it as the stronger choice for both single-threaded and multi-threaded applications.

The 41% advantage across all Cinebench versions is particularly telling. Rendering and video encoding workloads will see dramatic improvements. The 161.8% encryption advantage makes the i5-12490F mandatory for any security-focused build. Even in gaming, where single-thread performance matters most, the 28.5% PassMark lead indicates better frame rates in CPU-bound scenarios.

The i7-9700K retains value only for users with specific needs. Its extended instructions advantage could matter for certain scientific or engineering applications. Random string sorting performance may benefit database workloads. The integrated UHD Graphics 630 allows for a system without a discrete GPU. Overclocking potential, unlocked multiplier, and the $385 launch MSRP are historical facts, but the i7's end-of-life status and 14 nm architecture place it firmly in the past.

Users choosing between these two should pick the i5-12490F unless they specifically require the i7's niche strengths. The newer architecture, larger cache, lower TDP, and broader platform support make it the forward-looking choice. The i7-9700K is a capable processor, but the recorded data shows it is outclassed in nearly every measurable way.
