Intel Core i3-8300T vs Intel Core i7-10610U Comparison

The Intel Core i7-10610U and Intel Core i3-8300T are both 14 nm Intel parts, but they target very different corners of the market: one is a low-power mobile chip, the other a desktop processor. The benchmark data shows a consistent, nearly uniform performance gap across all tested workloads, with the mobile i7 winning every single head-to-head test. This is a curious inversion of expectations, as mobile parts typically sacrifice performance for efficiency. The data suggests that the i7-10610U’s higher boost clock and Hyper-Threading more than compensate for its lower base clock and lower TDP.

Head-to-Head Benchmarks

The results are remarkably consistent. In Cinebench R15 multicore, the i7-10610U scores 561 against the i3-8300T’s 469, a 19.6% lead. The single-core test tells a similar story: 79 versus 66, a 19.7% advantage. This pattern holds through every iteration of Cinebench. In R20 multicore, the scores are 2338 versus 1955 (19.6% delta), and in single-core, 330 versus 275 (20% delta). The R23 results reinforce the trend: multicore scores of 5569 versus 4656 (19.6% delta) and single-core scores of 786 versus 657 (19.6% delta).

The i7-10610U wins all six head-to-head tests. There is no benchmark in the data where the i3-8300T pulls ahead. The margins are almost identical, hovering around 19.6% to 20%. This uniformity suggests the performance difference is not workload-specific but rather a fundamental throughput advantage. The i7’s 8 threads versus the i3’s 4 threads likely drive the multicore gap, but the single-core lead is equally decisive. The i7’s 4.90 GHz boost clock versus the i3’s 3.20 GHz base clock (with no boost listed) explains the single-core dominance. The i3-8300T’s average benchmark score is 1586, placing it in the 39th percentile of all CPUs, while the i7-10610U’s average is 1611, also in the 39th percentile. Despite the i7’s clear win in direct comparison, their overall standings are similar, indicating both are mid-pack performers.

Architecture Differences

Both CPUs are built on Intel’s 14 nm process, but the underlying architectures differ. The i7-10610U uses Comet Lake-U, a mobile-focused design, while the i3-8300T uses Coffee Lake, a desktop architecture. Both have 4 physical cores, but the i7 supports 8 threads via Hyper-Threading, whereas the i3 is limited to 4 threads. This is the most significant architectural divergence. The i7’s base clock is 1800 MHz, which is low, but its boost clock reaches 4.90 GHz. The i3 has a higher base clock of 3.20 GHz but no listed boost clock, meaning it likely runs at a fixed frequency. The i7’s TDP is 25 watts versus the i3’s 35 watts, which is counterintuitive given the i7’s performance lead — the mobile chip achieves more with less power.

Cache configurations are identical on paper: 64 KB L1 per core, 256 KB L2 per core, and 8 MB shared L3. The i3-8300T has a listed die size of 126 mm², while the i7’s die size is not provided. Memory support differs: the i7 supports both DDR3 and DDR4, while the i3 supports only DDR4. The i3 has explicit memory bandwidth of 38.4 GB/s, whereas the i7’s bandwidth is not listed. ECC memory is supported on the i3 but not on the i7. The integrated graphics also differ: the i7 has UHD Graphics (unspecified variant), while the i3 has UHD Graphics 630. Socket compatibility is completely different — the i7 uses Intel BGA 1440 (soldered), and the i3 uses Intel Socket 1151 (LGA). PCIe support is Gen 3 for both, but the i3 lists 16 lanes (CPU only), while the i7 does not specify lane count.

FAQ

Q: Which CPU has a higher single-core performance?

A: The Intel Core i7-10610U wins every single-core test. In Cinebench R20 single-core, it scores 330 versus the i3-8300T’s 275, a 20% advantage. The gap is similar in R15 (79 vs 66) and R23 (786 vs 657).

The Verdict

The data is unambiguous: the Intel Core i7-10610U outperforms the Intel Core i3-8300T in every measured benchmark. The i7 leads by approximately 19.6% to 20% across all Cinebench tests, whether single-core or multi-core. This is a decisive victory, especially considering the i7 is a mobile chip with a lower TDP (25W versus 35W) and a much lower base clock. The i7’s 8 threads and 4.90 GHz boost clock are the primary drivers of its success. The i3-8300T’s only advantages are its higher base clock, ECC support, and explicit memory bandwidth figure. For users who prioritize raw processing power, the i7-10610U is the clear choice based on the benchmark data. However, the i3-8300T might appeal to those needing ECC memory or a fixed, predictable clock speed for specific desktop workloads. The i3’s launch MSRP of $138 is noted, but the i7’s price is not available.

Where Each One Wins

The i7-10610U wins in every benchmark category listed. It is the superior choice for multi-threaded workloads like video rendering, where its 5569 R23 multicore score outpaces the i3’s 4656. It also wins in single-threaded tasks like everyday responsiveness, with an R23 single-core score of 786 versus 657. The i7’s mobile design and lower TDP make it suitable for laptops and compact systems where power efficiency is important, yet it still delivers desktop-class performance. The i3-8300T, while losing all head-to-head tests, has its own niche. Its ECC memory support is a feature the i7 lacks, making it a candidate for error-sensitive computing. Its higher base clock of 3.20 GHz could be beneficial in scenarios where sustained, predictable performance is needed without boost fluctuations. The i3’s desktop socket (Socket 1151) offers upgradeability and user serviceability, unlike the soldered BGA 1440 of the i7. In summary, the i7-10610U is the performance winner across the board, while the i3-8300T offers specific features like ECC and a traditional desktop platform that may matter to a subset of users.
