CPU Comparison
Intel Core i7-10810U vs Core i7-8665U
A side-by-side comparison of specs, performance and value. Launched in April 2020, the Intel Core i7-10810U is a hexa-core mobile processor belonging to the 10th Gen Comet Lake-U family. It closely resembles the i7-10710U but is specifically tailored for OEMs, offering slightly tweaked clock speeds and a 25W TDP. With 6 cores and 12 threads, it provides robust multitasking capabilities for thin-and-light laptops. The processor operates at a 1.1 GHz base clock and can boost up to 4.9 GHz, ensuring strong single-threaded bursts for everyday tasks. Built on the 14nm process, it features 12MB of L3 cache and supports dual-channel DDR4 memory. Its integrated UHD Graphics handle standard media playback and light gaming. While it doesn't bring architectural innovations over standard Comet Lake parts, it remains a reliable option for business and premium consumer laptops needing balanced performance. The higher 4.9 GHz turbo compared to the 10710U gives it a slight edge in single-core workloads.

Our Verdict on Each
A solid OEM-specific 6-core processor that offers a slight frequency bump over the 10710U, making it excellent for business productivity and multitasking.
Best for: The Core i7-10810U is exclusively found in pre-built laptops, making it a factor only when shopping for used or refurbished business machines. It is a solid choice if you need a multitasking laptop for office work, heavy web browsing, and light content creation at a lower price point. The 6-core configuration ensures it can handle parallel tasks better than older 8th Gen chips. However, due to its 14nm heritage, battery life may suffer compared to newer laptops with 10nm or newer processors. Avoid paying a premium for this chip today; if the price is close to a laptop with an 11th Gen Intel or Ryzen 5000 processor, opt for the latter. It is best suited for budget-conscious buyers needing solid productivity performance.
