10th Gen Intel Core i5 10300H Review

The 10th Gen Intel Core i5 10300H is a 4-core, 8-thread Comet Lake processor running a 2.5 GHz base clock that boosts to 4.5 GHz within a 45 Watt TDP, a common entry point into gaming laptops of its generation.

As the entry-level H-series chip of its generation, it trades core count against the 6-core i7-10750H and 8-core i7/i9 chips above it, but retains a genuinely high boost clock for its tier.

Intel UHD Graphics 630

A basic integrated GPU intended for display output and light desktop use; laptops built around this chip almost universally pair it with a discrete GPU for actual gaming.

How Is the Core i5 10300H in Terms of Performance

The 4-core, 8-thread layout trails the 6-core and 8-core H-series chips of the same generation in multi-threaded work, while the high 4.5 GHz boost clock keeps everyday responsiveness and lightly-threaded gaming performance competitive.

Benchmarks

Cinebench R23 multi-core scores of 5,100 and single-core scores of 1,148 place this chip at the entry tier of Comet Lake H-series options. Geekbench 5 multi-core scores of 4,363 confirm solid but not class-leading multi-threaded capability for its generation.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

Entry-level gaming laptops of its generation wanting a genuine H-series chip at a lower price than 6-core and 8-core options

Not for

Buyers needing strong multi-threaded performance, the 6-core i7-10750H or 8-core i7-10870H offer meaningfully more within the same generation
