Intel Core i3-10105T vs Intel Core i3-8350K Comparison

Head-to-Head Benchmarks

The recorded data splits this comparison into two distinct camps. On one side, the Intel Core i3-8350K dominates Geekbench workloads. On the other, the Intel Core i3-10105T sweeps the entire Cinebench suite. The results are consistent within each of these groups, but the margins tell a fascinating story.

In Cinebench R15 multi-core, the Intel Core i3-10105T posts a score of 670 against the Intel Core i3-8350K's 593, a delta of -11.5%. The single-core run in that same benchmark shows the i3-10105T at 94 versus 83, a -11.7% gap. The pattern repeats in Cinebench R20, where the i3-10105T scores 2795 multi-core and 394 single-core against 2471 and 348, respectively. The margins stay remarkably stable near the -11.6% to -11.7% range. Cinebench R23 confirms the trend: 6656 multi-core for the i3-10105T, 5884 for the i3-8350K, and 939 single-core to 830, a -11.6% difference across the board.

The Geekbench results are the exact inverse, and here the i3-8350K is clearly ahead. In the multi-core test, the i3-8350K scores 4992, which is 36.8% ahead of the i3-10105T score of 3649. The single-core Geekbench result is 1564 for the i3-8350K, a 23.6% lead over the 1265 from the i3-10105T. The data is unambiguous: the i3-8350K wins 2 tests, the i3-10105T wins 6.

What could explain such a drastic difference across benchmark suites? The Cinebench margin is relatively modest, with the i3-10105T consistently leading by roughly 11.6% across all three versions of the suite. But the Geekbench results show the i3-8350K leading by over a third in multi-core and nearly a quarter in single-core. The benchmark methodology matters, and the database records show that an 11% deficit in Cinebench can sometimes flip to a 36.8% victory elsewhere. The i3-8350K averages a 2096 benchmark score overall, placing it in the 46th percentile of all CPUs, right next to the AMD Ryzen 7 1700X at 2094 with a delta of 0.1%. The i3-10105T sits at 2058 average, also in the 46th percentile, with the Intel Core i7-8350K's nearest rival, the i7-8705G, at 2058 and a 0 delta. The numbers are close enough in the aggregate that a user's workload is decisive.

The Cinebench wins for the i3-10105T range from 11.5% to 11.7%, all in the same direction. The Geekbench wins for the i3-8350K range from 23.6% to 36.8%, also all in the same direction. This suggests that the benchmark's choice of threading model and memory access patterns could be the deciding factor.

Where Each One Wins

The Intel Core i3-8350K wins Geekbench tests specifically. The data shows a 36.8% multicore lead and a 23.6% single-core lead. This makes its case for applications that stress the CPU in the way Geekbench models, where the i3-8350K's higher clock speed and 4 threads prove sufficient.

The Intel Core i3-10105T wins every Cinebench test, including R15, R20, and R23, in both single-core and multi-core tests, by a consistent 11.5% to 11.7% margin. Its 8 threads are the likely reason it pulls ahead in threaded Cinebench workloads. Yet, it still leads in single-core Cinebench as well, with a 94 versus 83 in R15 and a 939 versus 830 in R23.

For users running Cinebench-like rendering tasks, the i3-10105T is the clear choice from the data. For Geekbench-heavy usage, the i3-8350K is the one. The i3-8350K also has a higher average benchmark score, 2096 versus 2058, which points to a slight overall edge in the database's aggregate measurements, even as it loses a dedicated benchmark suite. The i3-10105T is active and currently produced, while the i3-8350K is end-of-life, which can matter for system longevity.

Specification Differences

The two CPUs share the same core count, 4 cores each, and the same L1 cache at 64 KB per core and L2 cache at 256 KB per core. They also share the same memory type, DDR4, and the same dual-channel memory bus, and both use PCIe Gen 3 with 16 lanes (CPU only). Both integrate UHD Graphics 630. The differences begin elsewhere.

The Intel Core i3-8350K uses the Intel Socket 1151, while the Intel Core i3-10105T uses the Intel Socket 1200. The i3-8350K runs at 4.00 GHz base, the i3-10105T runs at 3.00 GHz base.

The specification list shows a lower TDP of 35 watts versus 91 watts is a huge delta in power draw, which likely explains a lot about thermals. The 38.4 GB/s versus 42.7 GB/s memory bandwidth is the one spec where the i3-10105T is ahead, but it still loses Cinebench single-core tests, so bandwidth alone is not the deciding factor there.

Architecture Differences

The Intel Core i3-8350K is based on Coffee Lake architecture, specifically the Core i3 (Coffee Lake) generation, while the Intel Core i3-10105T is based on Comet Lake-R, part of the Core 10th Gen family. Both are built on Intel's 14 nm process node and made by Intel, so the transistor-level manufacturing process is identical.
