Intel Core i5-10500 vs Intel Core i7-8700
On paper, the Intel Core i7-8700 boosts higher. Specifications describe what each chip is designed to do; how much of that either one holds under continuous load is a separate question.

A check marks the higher figure only on rows where higher is unambiguously better. Rows without one are not ties; they are specifications where “better” has no meaning.
Reading the table
What the difference means.
Boost clock
The Core i7-8700 boosts to 4.6 GHz against 4.5 GHz, 2 percent higher. Across generations it is not a guide to speed on its own, for the reason above. Boost is also a peak: it is held for seconds to minutes, on one or two cores, while the cooling and the power limit allow. What either chip settles at under a long load is lower, and it depends on the cooler and the motherboard as much as the chip.
Power and cooling
Both are rated at 65 W, so they ask the same of a cooler and a power supply. The rating is the heat to be moved for the chip to hold its speed; both draw above it in short bursts, and either one slows down rather than fails when the cooling falls short.
Platform
They use different sockets, FCLGA1200 and FCLGA1151, so moving from one to the other means a new motherboard. For an upgrade, that cost belongs in the comparison; for a new build, the newer platform is the one with later chips still to come.
What no table says
How much of its speed a processor keeps after the first minute depends on the cooling and the power limit of the machine it is in. If you own one of these, measure it: the test is free and runs in this browser.
Questions
- Is the Core i5-10500 better than the Core i7-8700?
- On the specifications they are closely matched. No specification says how much speed either one keeps under a long load; that depends on the cooling and the power limit of the machine it is in, and it is what a sustained test measures.
- Do the Core i5-10500 and the Core i7-8700 use the same socket?
- No. The Core i5-10500 uses FCLGA1200 and the Core i7-8700 uses FCLGA1151, so switching means a new motherboard.
- Does the Core i5-10500 or the Core i7-8700 have integrated graphics?
- Both do: Intel UHD Graphics 630 on the Core i5-10500 and Intel UHD Graphics 630 on the Core i7-8700.

Every figure on this table is a design target. None of it is a measurement.
Nothing above describes how a processor behaves twenty minutes into a sustained workload, which is where two chips with nearly identical specifications routinely diverge. A boost clock is a ceiling the vendor permits, not a rate the chip sustains, and whether it holds depends on the cooling, the case, the power profile and the room. None of those appear on a specification sheet.
We deliberately do not reduce these figures to a single score. A composite invented from specifications would look authoritative and measure nothing, and choosing the weights would be choosing the winner.
