Intel Core i7-11700K vs Intel Core i7-14701TE Comparison

The Intel Core i7-14701TE and Intel Core i7-11700K are both 8-core, 16-thread desktop processors, yet they represent entirely different design philosophies and generations. The benchmark data reveals a clear split: the older 11700K dominates nearly every conventional workload, while the newer 14701TE shows specific strengths in specialized tasks. This analysis breaks down where each CPU excels, their architectural differences, and the exact performance deltas measured across a suite of 17 benchmarks.

Where Each One Wins

The Intel Core i7-11700K is the overwhelming winner in raw throughput, taking 15 of the 17 head-to-head benchmarks. Its victories span all Cinebench render tests, all PassMark general compute workloads, and every single-threaded measurement. The 11700K's advantage is broad and consistent, ranging from a narrow 1.8% lead in floating-point math to a massive 38.1% lead in random string sorting. This makes it the clear choice for content creation, software compilation, and everyday multitasking where sustained multi-core performance is paramount.

The Intel Core i7-14701TE wins only two benchmarks, but both are notable for their specificity. It takes the PassMark find prime numbers test by a staggering 116.7% margin, and the PassMark physics test by 79%. These wins suggest the newer architecture has improved integer-heavy mathematical routines and physics simulation capabilities, even if its overall clock speeds and power envelope are lower. For workloads that rely heavily on prime number generation or physics calculations, the 14701TE is the superior part. In all other measured scenarios, the 11700K is the definitive performance leader.

Architecture Differences

The two CPUs are built on fundamentally different silicon. The 14701TE uses the Raptor Lake architecture, specifically the Raptor Lake-R refresh, fabricated on a 10 nm process at Intel. It features a die size of 257 mm² and a 33 MB shared L3 cache, along with a 2 MB L2 cache per core. This newer design supports DDR4 and DDR5 memory, includes ECC memory support, and provides PCIe Gen 5 with 16 CPU lanes. It also integrates UHD Graphics 770.

In contrast, the 11700K uses the Rocket Lake architecture, built on a 14 nm process. It has a 16 MB shared L3 cache and a much smaller 512 KB L2 cache per core. Its memory support is limited to DDR4, and it lacks ECC memory capability. The 11700K offers PCIe Gen 4 with 20 CPU lanes and integrates UHD Graphics 750. Notably, the 11700K has an unlocked multiplier for overclocking, while the 14701TE is locked. The 11700K also carries a higher base clock of 3.60 GHz and a boost clock of 5.00 GHz, compared to the 14701TE's 2.10 GHz base and 5.20 GHz boost. The 14701TE's lower base clock and 45 W TDP reflect a focus on efficiency, whereas the 11700K's 125 W TDP prioritizes peak performance.

Head-to-Head Benchmarks

The benchmark data paints a decisive picture of the 11700K's dominance. In every Cinebench test, the older chip leads by a consistent margin of 17.6% to 17.7%. For example, in Cinebench R23 multi-core, the 11700K scores 20,666 against the 14701TE's 17,035, a 17.6% deficit for the newer part. The single-core results are equally one-sided, with the 11700K scoring 2,917 in Cinebench R23 single-core versus 2,405 for the 14701TE, again a 17.6% difference. This pattern holds across R15, R20, and R23, indicating a fundamental per-clock performance advantage for Rocket Lake in this rendering workload.

PassMark results show a similar trend, though with wider variance. The 11700K leads in data compression by 31.7% (322,689 vs 220,520), in data encryption by 25.2% (15,638 vs 11,699), and in extended instructions by 37.5% (22,964 vs 14,354). Integer math also favors the 11700K with a 23.8% lead (86,390 vs 65,792), while floating-point math is a near tie at a 1.8% difference (51,119 vs 50,219). The 11700K's advantage in multithreaded performance is 17.9% (24,408 vs 20,042), and its single-thread score of 3,390 is 22.2% higher than the 14701TE's 2,637. Random string sorting shows the largest gap, with the 11700K ahead by 38.1%.

The 14701TE's two wins are dramatic reversals. In the find prime numbers test, it scores 143 versus the 11700K's 66, a 116.7% advantage. This suggests a significant architectural improvement in the integer division and prime-checking algorithms used by Raptor Lake. Similarly, the physics test shows the 14701TE scoring 1,860 against the 11700K's 1,039, an 79% lead. These results indicate that while the 14701TE loses in aggregate throughput, its newer execution engine is markedly more efficient at specific computational patterns. The 11700K's wins range from minimal to crushing, but the 14701TE's two victories are among the largest deltas in the entire comparison.

Specification Differences

The two processors differ across nearly every core specification except for core and thread counts, both of which are 8 cores and 16 threads. The most significant differences are in clock speed and power. The 11700K has a 3.60 GHz base clock and a 5.00 GHz boost clock, while the 14701TE runs at 2.10 GHz base and 5.20 GHz boost. The 14701TE has a 45 W TDP, a figure less than half of the 11700K's 125 W TDP. The 11700K is unlocked for overclocking; the 14701TE is not.

Memory and platform support also diverge. The 14701TE supports both DDR4 and DDR5 memory, while the 11700K is limited to DDR4. The 14701TE supports ECC memory; the 11700K does not. The 14701TE uses the Intel Socket 1700, while the 11700K uses the older Intel Socket 1200. PCIe capabilities differ as well, with the 14701TE offering Gen 5 with 16 lanes and the 11700K offering Gen 4 with 20 lanes. The integrated graphics are different, with the 14701TE featuring UHD Graphics 770 and the 11700K featuring UHD Graphics 750. Finally, the cache hierarchy is distinct: the 14701TE has a 2 MB L2 cache per core and 33 MB shared L3, whereas the 11700K has 512 KB L2 per core and 16 MB shared L3. The 11700K was released in March 2021 and is now end-of-life; the 14701TE was released in June 2024 and remains active. The 11700K had a launch MSRP of $399.
