Intel Core i5-8300H vs Intel Core i7-7700T Comparison

The data tells a straightforward story: the Intel Core i7-7700T wins 7 of 8 recorded benchmarks against the Intel Core i5-8300H, though the margins are narrow enough that both chips sit in the same performance band. Both carry an identical average ranking position, landing at the 45th percentile versus all CPUs in the database. The i7-7700T posts a slightly higher average benchmark score of 2039 against 2005 for the i5-8300H, a gap of under two percent. This is a contest between two 4-core, 8-thread Intel parts built on the same 14 nm process, and the outcome is decided in the details of clocks, cache, and thermals rather than in any structural difference.

Head-to-Head Benchmarks

The sweep is almost clean for the i7-7700T. In Cinebench R15 multi-core it scores 646 against 629, a 2.7 percent win, and it repeats that pattern across the rest of the Cinebench suite: R20 multi-core goes 2692 to 2622 (2.7 percent), R23 multi-core goes 6410 to 6245 (2.6 percent), and the single-core runs follow suit. R15 single-core lands at 91 versus 88 (3.4 percent), R20 single-core at 380 versus 370 (2.7 percent), and R23 single-core at 905 versus 881 (2.7 percent).

Geekbench multi-core is nearly a tie: 3938 for the i7-7700T versus 3920 for the i5-8300H, a 0.5 percent difference that amounts to background noise. The one clear exception in the entire data set is Geekbench single-core, where the i5-8300H takes the win at 1286 against 1248, a 3 percent advantage for the newer chip. That result is consistent with its higher boost clock, which matters in short, bursty workloads that Geekbench tends to favor.

The pattern is therefore consistent and legible: the i7-7700T holds a steady 2.6 to 3.4 percent lead in every Cinebench test, the two chips are effectively tied in Geekbench multi-core, and the i5-8300H edges ahead only in Geekbench single-core. None of these margins represents a meaningful performance class difference.

Where Each One Wins

For sustained rendering workloads, the i7-7700T is the stronger recorded performer. Every Cinebench multi-core result favors it, which indicates that it holds its clock speeds better under extended all-core load despite a lower rated power envelope. Content creators running Cinebench-style rendering, encoding, or sustained threaded compute will find the data favors the i7-7700T, even if only by roughly three percent.

The i5-8300H's lone win, Geekbench single-core at 1286 versus 1248, points to burst-oriented responsiveness. Its higher boost clock of 3.90 GHz against 3.80 GHz gives it the edge in short single-threaded bursts, which aligns with the demands of everyday desktop tasks and applications that briefly spike a single thread. It also carries a larger shared L3 cache, 12 MB against 8 MB, which can help in cache-sensitive workloads even where the benchmark numbers do not show a dramatic effect.

It is worth contextualizing both chips against the wider field. The i7-7700T's nearest rivals in the database include the AMD Opteron 6386 SE (average score 2038, 0.1 percent delta), the Intel Core i7-3960X (2037, 0.1 percent), the Intel Xeon E3-1275 v5 (2043, -0.2 percent), and the AMD Ryzen 5 4500U (2035, 0.2 percent). The i5-8300H sits among the Intel Xeon D-1712TR (2004, 0 percent delta), the Intel Core i5-8400H (2003, 0.1 percent), the AMD Ryzen 7 2800H (2002, 0.2 percent), and the Intel Core i5-8400T (2001, 0.2 percent). Both chips cluster tightly with their respective neighbors, confirming that these are same-tier parts rather than class-leading performers.

Architecture Differences

Both processors come from Intel, use the same 14 nm process node from Intel's own foundry, and share an identical core and thread configuration of 4 cores and 8 threads. Neither offers an unlocked multiplier, and both support DDR4 memory without ECC.

The architectural distinction is generational. The i7-7700T is a Kaby Lake desktop part on Intel Socket 1151, while the i5-8300H is a Coffee Lake-H mobile part soldered to an Intel BGA 1440 package. The i5-8300H is the newer design, released 2018-04-01, against 2017-01-02 for the i7-7700T, and it is the only one of the two with a recorded die size of 126 mm².

Cache is where the silicon differs most concretely. Both have 64 KB of L1 per core and 256 KB of L2 per core, but the i5-8300H carries 12 MB of shared L3 against 8 MB for the i7-7700T, a 50 percent larger last-level cache. Clock behavior also splits: the i7-7700T has the higher base clock at 2.90 GHz versus 2.30 GHz, while the i5-8300H has the higher boost at 3.90 GHz versus 3.80 GHz. That combination explains almost everything in the benchmark table, since the i7-7700T's base-clock advantage shows up in sustained Cinebench runs and the i5-8300H's boost advantage shows up in Geekbench single-core.

The i7-7700T records richer platform data: dual-channel memory with 38.4 GB/s of bandwidth and PCIe Gen 3 with 16 CPU lanes. The i5-8300H has no memory bus, bandwidth, or PCIe figures recorded in the database. Integrated graphics differ slightly: HD 630 on the i7-7700T versus UHD 630 on the i5-8300H. Production status also diverges: the i7-7700T is listed as Active, while the i5-8300H is End-of-life.

FAQ

The Verdict

The recorded data favors the Intel Core i7-7700T for sustained multi-core work. It wins every Cinebench test by 2.6 to 3.4 percent, ties in Geekbench multi-core, and does so within a lower rated power envelope of 35 W versus 45 W for the i5-8300H. Anyone prioritizing rendering throughput or long-running threaded compute should pick the i7-7700T based on these numbers.

The i5-8300H makes its case on burst responsiveness and cache. Its 3 percent Geekbench single-core win, higher boost clock, and 50 percent larger L3 cache suit it to single-thread-bursty workloads, and its Coffee Lake-H generation is the newer architecture of the two. Neither chip offers a class advantage, both sitting at the 45th percentile with average scores within two percent of each other. Buyers choosing between them are choosing a platform, a power target, and a socket, not a performance tier: Socket 1151 desktop on Kaby Lake, or BGA 1440 mobile on Coffee Lake-H.
