Intel Core i3-12100T

The Intel Core i3-12100T is a 4-core, 8-thread desktop processor in Intel's Core 12th Gen family. Built on Alder Lake-S at Intel's 10nm process, it uses Intel Socket 1700 and includes UHD Graphics 730. It supports DDR4 and DDR5 through a dual-channel memory bus, with a 35W TDP and a launch MSRP of $122. The benchmark database places the chip at the 56th percentile of all CPUs, with an average benchmark score of 3309.

Benchmark Performance

Across the recorded benchmark suite, the Core i3-12100T posts an average benchmark score of 3309. That score sits at the 56th percentile of all CPUs, putting the chip in the middle of the performance distribution rather than at the top. The individual results are consistent with that positioning. Cinebench R15 shows a multicore score of 1072 and a single-core score of 151. Cinebench R20 produces a multicore score of 4467 and a single-core score of 630. Cinebench R23 reaches a multicore score of 10636 and a single-core score of 1501. Geekbench reports a multicore score of 6055 and a single-core score of 1957.

The Cinebench R23 multicore result is the strongest multi-thread output in this data set, and the single-core scores are solid for a 35W part. The 56th percentile rank indicates that the chip sits in the broad middle of the CPU database, but the score spread shows that it is not a low-end part. The average score of 3309 is closely mirrored by the nearest rivals, with the largest gap between them being only 0.2%. The i3-12100T trails the Intel Core i5-11400T by 0.1% and the Intel Xeon E5-1660 v4 by 0.1%, while leading the AMD Ryzen 3 5300G by 0.2% and the AMD Ryzen 5 PRO 2600 by 0.2%. These are narrow margins, and benchmark results indicate that the i3-12100T is effectively a peer of all four chips.

The Geekbench multicore score of 6055 and single-core score of 1957 round out the picture. The Cinebench multicore numbers are much larger than their single-core counterparts, which is consistent with a 4-core, 8-thread processor that uses all threads in rendering workloads. The benchmark data shows a CPU that handles both single-thread and multi-thread tests without a severe weakness in either category.

How It Compares

The nearest-rival data places the i3-12100T in a tightly packed group. Against the Intel Core i5-11400T, the i3-12100T's average score of 3309 is 0.1% below the rival's 3312. That is a negligible gap in aggregate benchmark terms, and the two Intel parts land in the same performance tier.

Against the Intel Xeon E5-1660 v4, the i3-12100T again trails by 0.1%, with the Xeon averaging 3313. The delta is tiny, so the benchmark data treats the Core i3 and the older Xeon as near equivalents. The i3-12100T does not need a workstation platform to reach that score.

Against the AMD Ryzen 3 5300G, the i3-12100T is 0.2% ahead, with the Ryzen averaging 3303. The direction of the delta favors the Intel chip, but the margin is small enough that the two processors should be considered comparable in aggregate performance.

Against the AMD Ryzen 5 PRO 2600, the i3-12100T again leads by 0.2%, with the Ryzen averaging 3303. The i3-12100T's average score of 3309 is only a few benchmark points above that figure, so this matchup is also a near tie. Across the four nearest rivals, the maximum delta is 0.2%, meaning the i3-12100T sits in a very crowded performance band.

Power and Thermals

The Core i3-12100T is rated at a 35W TDP, placing it in a low-power desktop class. That is a key fact for thermal planning. A 35W chip does not require an aggressive cooling solution; the implied cooling tier is a basic air cooler sufficient for the processor's heat output. The 10nm Alder Lake-S die is 163 mm², and the chip has a 2.20GHz base clock with a 4.10GHz boost clock. The locked multiplier means the CPU runs at Intel's stock clock settings, so the 35W TDP defines the intended operating envelope.

The integrated UHD Graphics 730 also affects system thermals indirectly. Because the CPU includes its own graphics solution, a separate GPU is not required for basic display output, which keeps overall system power and heat lower in simple builds. The data shows a processor designed for efficiency rather than extreme overclocking. The base clock of 2.20GHz is conservative, while the 4.10GHz boost clock gives the chip a wide operating range. For cooling, the 35W TDP is the specification that matters most, and it points to a modest thermal solution.

Single-Thread vs Multi-Thread Behavior

The i3-12100T's benchmark results show a clear split between single-thread and multi-thread performance. In Cinebench R15, the single-core score is 151 and the multicore score is 1072. In Cinebench R20, the single-core score is 630 and the multicore score is 4467. In Cinebench R23, the single-core score is 1501 and the multicore score is 10636. These three Cinebench runs all show the same pattern: the multicore score is far higher than the single-core score, reflecting the work done by all 8 threads.

Geekbench tells a slightly different story. The single-core score is 1957 and the multicore score is 6055. The gap between the two is less dramatic than in Cinebench, which suggests that Geekbench's mixed workload does not scale as uniformly across all threads. For real workloads, that split means the i3-12100T should feel responsive in lightly threaded tasks, thanks to the 4.10GHz boost clock, while still delivering meaningful multi-thread output in rendering and content-creation applications.

The base clock of 2.20GHz is low, but the boost clock of 4.10GHz provides the single-thread headroom. The 8 threads and 12 MB of shared L3 cache give the chip enough resources for threaded workloads. The benchmark data shows a processor that leans on its high boost clock for single-thread performance and on its full 4-core, 8-thread layout for multi-thread performance. That combination explains the 56th percentile average standing and the narrow margins against its nearest rivals.
