Intel Core i3-4350T vs Intel Core i3-8145U Comparison

The Intel Core i3-8145U and the Intel Core i3-4350T are two dual-core, four-thread processors from different eras and market segments. One is a 15-watt mobile part built on a newer process, the other a 35-watt desktop chip from an older generation. Benchmark results from the database show a clear pattern across all recorded Cinebench tests, with the newer mobile chip posting higher scores in every single measurement. The data shows that the gap is consistent, roughly 18 to 19 percent, regardless of whether the workload is single-threaded or multi-threaded.

Head-to-Head Benchmarks

The recorded head-to-head results are unambiguous. The Intel Core i3-8145U wins all five benchmark comparisons, and the Intel Core i3-4350T does not win a single test. The biggest margins appear in both the multi-core and single-core tests, with the delta hovering near the same figure across the board.

In Cinebench R15 multi-core, the Intel Core i3-8145U scores 322 while the Intel Core i3-4350T scores 271. That translates to an 18.8 percent advantage for the mobile chip. The same 18.8 percent delta appears again in Cinebench R20 multi-core, where the Intel Core i3-8145U hits 1342 and the Intel Core i3-4350T reaches 1130. This consistency is notable, it suggests that the performance gap is not workload-specific but rather a general characteristic of the two architectures and their respective operating conditions.

Single-core performance tells a similar story, though the numbers are smaller in absolute terms. In Cinebench R20 single-core, the Intel Core i3-8145U scores 189, and the Intel Core i3-4350T scores 159. The delta here is 18.9 percent, the largest percentage difference of any recorded test. Cinebench R23 single-core shows the Intel Core i3-8145U at 451 and the Intel Core i3-4350T at 380, an 18.7 percent gap. The R23 multi-core test mirrors that exactly, with the Intel Core i3-8145U scoring 3196 versus 2692 for the Intel Core i3-4350T, again an 18.7 percent difference.

The average benchmark score in the database reinforces this hierarchy. The Intel Core i3-8145U carries an average score of 941, while the Intel Core i3-4350T sits at 926. Both processors land in the 25th percentile of all CPUs tracked by the database, meaning they are in the same performance tier overall. But within that tier, the Intel Core i3-8145U is consistently the stronger performer. Its nearest rivals in the database include the Intel Core i7-2715QE with an average score of 942, a delta of -0.1 percent, and the AMD Athlon X4 860K with 943, a delta of -0.2 percent. The Intel Core i3-4350T, by contrast, sits near the Intel Core i5-4288U at 927 and the Intel Core i7-870 at 928. The context shows that neither chip is a standout in the broader CPU landscape, but the Intel Core i3-8145U has a measurable edge over its older desktop counterpart.

Architecture Differences

The two processors come from different architectural generations and are built on different process nodes. The Intel Core i3-8145U uses the Whiskey Lake architecture, with the codename Whiskey Lake-U, and is built on a 10 nm process node. The Intel Core i3-4350T uses the Haswell architecture, codename Haswell, on a 22 nm process node. The newer process node is a significant differentiator, as it allows for higher transistor density and lower power operation in the mobile part, which operates at a 15-watt TDP.

The Intel Core i3-4350T has documented transistor counts and die size figures in the database, listing 1,400 million transistors and a die size of 177 mm². The Intel Core i3-8145U does not have transistor or die size data recorded. Cache configuration is identical in structure, both chips have 64 KB L1 cache per core, 128 KB L2 cache per core, and 4 MB shared L3 cache. The Intel Core i3-8145U lists L2 cache at 256 KB per core rather than 128 KB per core, but the total L3 is still 4 MB shared. Both are dual-core processors with four threads.

The integrated graphics differ as well. The Intel Core i3-8145U comes with UHD Graphics 620, while the Intel Core i3-4350T uses Intel HD 4600. The database does not record performance figures for these iGPUs, so any comparison must remain qualitative. The Intel Core i3-8145U is designed for the mobile market segment and uses the Intel BGA 1528 socket, while the Intel Core i3-4350T is a desktop part using the Intel Socket 1150.

Where Each One Wins

The Intel Core i3-8145U wins every benchmark recorded in the database, so the use-case split is heavily in its favor. In multi-threaded workloads like Cinebench R23 multi-core, the Intel Core i3-8145U scores 3196 versus 2692, a lead of 18.7 percent. In single-threaded workloads like Cinebench R23 single-core, the Intel Core i3-8145U scores 451 versus 380, also an 18.7 percent lead. This consistency means that for any application that relies on CPU compute throughput, whether it is rendering, encoding, or general productivity, the Intel Core i3-8145U is the better choice. The Intel Core i3-4350T is not without its own advantages, it has a higher base clock at 3.10 GHz, and it has a desktop socket that may be easier to fit in legacy builds, and it supports DDR3 memory, which could be useful for older platforms. The Intel Core i3-4350T also has a lower launch MSRP of $138, and it is a desktop part with a 35-watt TDP, which might be a consideration for builds where that form factor is a requirement. But for raw performance as measured by Cinebench, the Intel Core i3-8145U takes the win in every recorded test. For users who prioritize performance, the Intel Core i3-8145U is the clear winner. For users who need a desktop processor with a higher base clock and a lower launch MSRP, the Intel Core i3-4350T has its place.

The Verdict

The data points to a straightforward conclusion. The Intel Core i3-8145U outperforms the Intel Core i3-4350T in every single benchmark recorded in the database, with deltas ranging from 18.7 percent to 18.9 percent. The Intel Core i3-8145U has a 15-watt TDP and a newer 10 nm process node, while the Intel Core i3-4350T has a 35-watt TDP and a 22 nm process node. The Intel Core i3-8145U also supports DDR4 memory with higher bandwidth at 38.4 GB/s, while the Intel Core i3-4350T supports DDR3 at 25.6 GB/s. Both processors are in the 25th percentile of all CPUs, meaning neither is a top performer in the broader market, but the Intel Core i3-8145U is consistently ahead of the Intel Core i3-4350T. The Intel Core i3-8145U is the better performer for any workload that leverages its boost clock, which reaches 3.90 GHz, and its newer architecture. The Intel Core i3-4350T offers a higher base clock at 3.10 GHz and a lower launch MSRP of $138, but the benchmark results show that this does not translate into higher performance. The Intel Core i3-8145U is the processor to pick for anyone who wants the higher scores, and the Intel Core i3-4350T is the processor to pick for those who specifically need a desktop chip with a 35-watt TDP and DDR3 support. The benchmark results are clear, the Intel Core i3-8145U wins five out of five recorded comparisons, and the Intel Core i3-4350T wins none. That is the entire story, and the numbers do not leave much room for debate.
