CPU Comparison

The Intel Core i3-12100TE and Intel Core i5-8600 land nearly on top of each other in aggregate performance, with the 12100TE averaging 2475 across all benchmark runs and the 8600 averaging 2454. That 0.8% gap places both chips within the same competitive tier, and the head-to-head results confirm it: the 12100TE wins all six Cinebench comparisons, but never by more than 0.8%. In practical terms, these are equivalent processors for most workloads, though the 12100TE holds a consistent, if narrow, edge in every measured test.

Head-to-Head Benchmarks

The 12100TE’s sweep is uniform rather than dramatic. In Cinebench R15 multi-core, it scores 862 against the 8600’s 855, a 0.8% margin. Single-core R15 shows the same pattern: 121 versus 120, again 0.8% apart. Moving to Cinebench R20, the 12100TE posts 3594 multi-core and 507 single-core, while the 8600 manages 3564 and 503 respectively. The delta stays locked at 0.8% across both subtests. Cinebench R23 repeats the story: 8558 versus 8486 in multi-core, and 1208 versus 1198 in single-core, with the same 0.8% delta.

What matters here is consistency. The 12100TE does not win because of a single workload quirk; it wins every iteration of the Cinebench suite, from R15 through R23, in both single- and multi-threaded modes. The largest absolute gap is just 72 points in R23 multi-core, which is well within run-to-run variance for most systems. However, the fact that the 12100TE leads in all six tests suggests a genuine, if small, architectural advantage rather than noise. The 8600’s best showing is its R20 multi-core score, where it trails by only 30 points, a 0.8% deficit that mirrors the overall trend.

For builders, this means the benchmark data will not decide the choice. Neither chip offers a meaningful performance lead in Cinebench. The 12100TE’s percentile ranking of 49 versus the 8600’s 48 reflects this near-tie, and its nearest-rival list includes the 8600 at a 0.8% delta, confirming that these two processors are direct competitors. The 8600’s own nearest rivals include the Core i5-10500 and Xeon D-1540, both within 0.3%, so it sits in a dense cluster of similarly performing CPUs.

Architecture Differences

The 12100TE is built on Alder Lake-S using Intel’s 10 nm process, while the 8600 uses Coffee Lake on 14 nm. That process gap delivers real efficiency benefits: the 12100TE has a 35 W TDP against the 8600’s 65 W, which is a substantial reduction for the same performance level. The 12100TE’s die size is 163 mm² versus 154 mm² for the 8600, and it packs 4 cores and 8 threads, whereas the 8600 offers 6 cores and 6 threads. The 12100TE compensates for fewer physical cores with Hyper-Threading, giving it 8 threads to the 8600’s 6.

Cache layouts differ significantly. The 12100TE allocates 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The 8600 uses 64 KB L1 per core, 256 KB L2 per core, and 9 MB of shared L3. The 12100TE’s larger per-core L2 and bigger L3 pool help explain how a 4-core part keeps pace with a 6-core chip in multi-threaded tests. The 12100TE also supports both DDR4 and DDR5 memory, while the 8600 is limited to DDR4. The 8600 lists a memory bandwidth of 42.7 GB/s; the 12100TE does not have a specified bandwidth figure in the data.

PCIe connectivity is another differentiator. The 12100TE provides Gen 5 with 20 CPU lanes, while the 8600 offers Gen 3 with 16 lanes. That is a forward-looking advantage for the 12100TE, though it only matters with compatible hardware. Integrated graphics differ as well: the 12100TE carries UHD Graphics 730, and the 8600 has UHD Graphics 630. Both chips are socket-incompatible, the 12100TE uses Intel Socket 1700, the 8600 uses Intel Socket 1151, so upgrading between them requires a new motherboard. The 12100TE remains in active production, while the 8600 is end-of-life with a release date of 2018-02-13.

Where Each One Wins

The 12100TE wins every benchmark in the dataset, so the use-case split is not about raw performance. Instead, the differentiators are efficiency, platform, and thread count. The 12100TE’s 35 W TDP makes it the clear choice for compact builds, small-form-factor systems, or any scenario where heat and power draw are priorities. It delivers the same Cinebench scores as the 8600 while consuming nearly half the power envelope, which is a meaningful advantage in constrained chassis or always-on machines.

The 8600’s six physical cores without Hyper-Threading might appeal to workloads that prefer discrete cores over logical threads, but the benchmark data does not show any such benefit in Cinebench. The 8600’s higher base clock of 3.10 GHz and boost of 4.30 GHz, against the 12100TE’s 2.10 GHz base and 4.00 GHz boost, do not translate into wins. The 12100TE’s newer architecture and larger cache overcome the clock deficit, so the 8600 has no measured advantage in any test.

For builders with an existing Socket 1151 motherboard, the 8600 is the drop-in option, but for new builds the 12100TE offers the same performance with better efficiency and a modern platform. The 12100TE’s support for DDR5 and PCIe Gen 5 gives it a future-proofing edge, though the 8600’s DDR4 support is still perfectly serviceable. The 8600’s launch MSRP was $213, while the 12100TE launched at $125, but those figures are historical and do not reflect current market conditions.

The Verdict

The data points to the Intel Core i3-12100TE as the better buy for almost every scenario. It wins all six Cinebench tests, albeit by a narrow 0.8% margin, and does so while using a 35 W TDP against the 8600’s 65 W. The 12100TE also brings a newer socket, DDR5 support, PCIe Gen 5, and active production status. Its 4-core/8-thread configuration with 12 MB of L3 cache matches the 8600’s 6-core/6-thread setup with 9 MB of L3 in performance, which speaks to the efficiency of the Alder Lake architecture.

The only reason to choose the 8600 is if you already own a Socket 1151 motherboard and want to avoid a platform change. In a fresh build, the 12100TE is strictly better: equal or slightly higher scores, half the TDP, and a platform with more headroom. The 8600’s end-of-life status also means no future support, while the 12100TE is still active. The percentile rankings, 49 for the 12100TE versus 48 for the 8600, reinforce that the 12100TE is the marginally stronger performer overall.

Pick the 12100TE for new systems, low-power builds, or any machine where efficiency matters. Pick the 8600 only for socket compatibility with an existing 1151 board, accepting that you are getting slightly lower performance and much higher power draw.
