Intel Core i3-1220P vs Intel Core i5-12600T Comparison

The Intel Core i3-1220P and Intel Core i5-12600T are both Alder Lake parts, but they target different corners of the market: one is a mobile chip, the other a desktop chip. The data reveals a consistent pattern of dominance by the i5-12600T, yet the i3-1220P manages to carve out a couple of narrow victories. The benchmark results show a clear hierarchy, with the desktop part leading in 15 of the 17 head-to-head tests, while the mobile chip takes only 2 wins.

Head-to-Head Benchmarks

The most striking pattern is the i5-12600T’s dominance across Cinebench. In the R15 multicore test, the i5 scores 1494 against the i3’s 1341, a 10.2% gap. The single-core R15 result tells a similar story: 210 versus 189, a 10% lead. This trend holds steady through R20 and R23, where the i5-12600T leads by 10.2% in both multicore runs and by 10.1% to 10.2% in single-core runs. The consistency of this ~10% advantage across all Cinebench versions suggests a fundamental per-clock or architectural edge rather than a workload-specific quirk.

Moving to PassMark, the i5-12600T’s lead becomes more varied and sometimes much larger. In extended instructions, the i5 posts 13140 versus the i3’s 10051, a 23.5% advantage. The physics test is even more lopsided: 1212 versus 637, a 47.4% gap. Find prime numbers shows the biggest disparity of all, with the i5 scoring 76 against the i3’s 33, a 56.6% difference. These are not marginal wins; they indicate the i5-12600T has substantially more headroom in compute-heavy integer and physics workloads.

The i5-12600T also wins in multithreaded throughput, posting 17446 versus 14481 in PassMark multithread, a 17% lead. Floating point math follows with 42295 versus 37294, an 11.8% edge. Integer math is closer, with the i5 at 54646 and the i3 at 53507, a 2.1% difference. Data compression favors the i5 at 195924 versus 180528, a 7.9% gap. Even single-thread performance, where the i3’s higher boost clock might help, goes to the i5: 3516 versus 3362, a 4.4% lead.

The i3-1220P’s two wins are narrow and specific. In data encryption, it scores 10923 against the i5’s 10205, a 7% advantage. In random string sorting, it wins 20846 versus 20299, a 2.7% lead. These are the only two tests where the mobile chip comes out ahead, and both are relatively niche workloads. The data does not show any other test where the i3-1220P closes the gap to within single digits.

The Verdict

The verdict from the benchmark data is unambiguous: the Intel Core i5-12600T is the stronger processor in nearly every measurable way. It wins 15 of 17 head-to-head comparisons, including all six Cinebench tests and all PassMark tests except two. The i5’s leads range from a modest 2.1% in integer math to a commanding 56.6% in find prime numbers. For users seeking maximum throughput in rendering, physics simulation, or extended instruction workloads, the i5-12600T is the clear choice.

The i3-1220P is not without merit, but its victories are isolated. It wins in data encryption and random string sorting, which suggests it has a specific strength in certain memory-access or cryptographic patterns. However, these wins do not offset the broader trend. The i5-12600T also holds a lead in single-thread performance, which is critical for everyday responsiveness and lightly-threaded applications.

Given the data, the i5-12600T is the pick for anyone prioritizing raw performance across a wide range of tasks. The i3-1220P is only preferable in the narrow scenario where encryption or string sorting is the primary workload, and even then the overall performance deficit in other areas may be a concern. The percentile rankings are identical at 74 for both, but the average benchmark scores tell a slightly different story: the i3-1220P averages 21066, while the i5-12600T averages 20917, a difference of less than 1% in favor of the i3. This is a curious anomaly, given the head-to-head results, but it likely reflects the mix of tests included in the average.

Architecture Differences

Both processors are built on Intel’s 10 nm process node and use the Alder Lake architecture. The key architectural difference lies in the chip design and target platform. The i3-1220P is part of the Alder Lake-P mobile family, with a codename of Alder Lake-P. It uses the Intel BGA 1744 socket, which is a soldered mobile package. The i5-12600T is from the Alder Lake-S desktop family, with a codename of Alder Lake-S, and uses the Intel Socket 1700, a standard desktop LGA socket.

The core configurations differ significantly. The i3-1220P has 10 cores and 12 threads, while the i5-12600T has 6 cores and 12 threads. Despite having fewer physical cores, the i5-12600T delivers higher performance, which points to differences in core types or clock behavior that are not fully captured in the core count alone. The i5-12600T also has a larger L3 cache: 18 MB shared versus the i3’s 12 MB shared. Both share the same per-core L1 and L2 cache sizes of 80 KB and 1.25 MB, respectively.

Another notable architectural difference is the integrated graphics. The i3-1220P comes with UHD Graphics 64EU, while the i5-12600T features UHD Graphics 770. The PCIe support also differs: the i3-1220P offers Gen 4 with 20 lanes (CPU only), while the i5-12600T offers Gen 5 with 20 lanes (CPU only). The i5-12600T is a desktop part with a larger die size of 163 mm², whereas the i3-1220P’s die size is not listed in the data.

Specification Differences

The specification differences between the two parts are substantial, despite both being Alder Lake. The core count is the most obvious: 10 cores for the i3-1220P versus 6 cores for the i5-12600T. Thread counts are equal at 12. Base clocks differ sharply: the i3-1220P runs at 1500 MHz, while the i5-12600T runs at 2100 MHz. Boost clocks are closer, with the i3 at 4.40 GHz and the i5 at 4.60 GHz, giving the i5 a 0.2 GHz advantage.

Thermal design power is another differentiator. The i3-1220P has a TDP of 28 watts, while the i5-12600T has a TDP of 35 watts. This indicates the desktop part is allowed to draw more power, which likely contributes to its higher performance. The sockets are entirely different: Intel BGA 1744 for the i3-1220P and Intel Socket 1700 for the i5-12600T. Market segments also differ: the i3-1220P is a mobile part, while the i5-12600T is a desktop part.

Memory support is identical for both: DDR4 and DDR5, dual-channel. ECC memory is not supported on either. The i5-12600T has a listed part number of SRL5U and a launch MSRP of $223, while the i3-1220P has a part number of SRLFY and no launch MSRP listed. The i5-12600T’s release date is not provided, but the i3-1220P was released on 2022-02-22.

Where Each One Wins

The Intel Core i5-12600T is the winner in the vast majority of scenarios. Its 10.2% lead across all Cinebench multicore and single-core tests makes it the better choice for rendering, video encoding, and any CPU-intensive creative work. The 47.4% lead in physics and the 56.6% lead in find prime numbers indicate a significant advantage in scientific computing and simulation tasks. The 17% lead in multithreaded performance and 11.8% lead in floating point math further cement its position for heavy parallel workloads. The i5-12600T’s higher boost clock of 4.60 GHz and larger L3 cache likely contribute to these wins.

The Intel Core i3-1220P wins in two specific areas. Data encryption shows a 7% lead, suggesting it handles cryptographic workloads more efficiently. Random string sorting shows a 2.7% lead, which could indicate a slight advantage in certain data-processing tasks. However, these wins are narrow and isolated. The i3-1220P’s lower TDP of 28 watts and mobile BGA 1744 socket make it a more power-efficient choice for laptops, but the data does not show a performance benefit outside the two niche tests. For any user who values overall performance, the i5-12600T is the data-backed recommendation. For users with workloads dominated by encryption or string sorting, the i3-1220P offers a small edge, but the i5-12600T’s broader strengths are hard to ignore.
