Intel Core i7-10700K vs AMD Ryzen 7 8700G

On the specifications we can verify, the Intel Core i7-10700K and the AMD Ryzen 7 8700G are closely matched. Which one is faster on your desk depends on cooling and sustained behaviour rather than on anything printed here.

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.

4 years apart

The Ryzen 7 8700G (Ryzen 8000G (Phoenix, Zen 4), 2024) is 4 years newer than the Core i7-10700K (Comet Lake (10th gen), 2020). That matters more than any single row in the table, because a newer design usually does more work in each clock cycle. Clock speeds are only a fair comparison between chips of the same generation; across a gap this wide, a lower number on the newer chip can still be the faster core.

Power and cooling

The Core i7-10700K is rated at 125 W against 65 W. The rating is the heat the cooler has to move for the chip to hold its speed, and modern chips draw well above it in short bursts. A tower cooler or a liquid loop suits the Core i7-10700K; the Ryzen 7 8700G is easier to keep quiet and fits smaller cases. A chip whose cooling falls short does not fail. It slows down, and it does so after the first minute, which is why short benchmarks miss it.

Platform

They use different sockets, FCLGA1200 and AM5, so moving from one to the other means a new motherboard, and new memory as well: FCLGA1200 takes DDR4, AM5 takes DDR5. 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.

Manufacturing process

The Ryzen 7 8700G is built on a 4 nm process against 14 nm. A finer process generally does the same work for less power. The names are marketing labels rather than measurements, though, and they are not comparable between manufacturers, so treat the row as a sign of how recent the design is and no more.

Which to pick, on paper

A quiet or compact build: Ryzen 7 8700G; 65 W against 125 W: less heat to move, so a smaller cooler and slower fans.

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 i7-10700K better than the Ryzen 7 8700G?: The Ryzen 7 8700G is the newer design by 4 years, which usually means faster cores. By need, on the specifications: a quiet or compact build: the Ryzen 7 8700G. 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 i7-10700K and the Ryzen 7 8700G use the same socket?: No. The Core i7-10700K uses FCLGA1200 and the Ryzen 7 8700G uses AM5, so switching means a new motherboard and new memory.
Does the Core i7-10700K or the Ryzen 7 8700G have integrated graphics?: Both do: Intel UHD Graphics 630 on the Core i7-10700K and AMD Radeon 780M (RDNA 3, 12 CU, 2.9 GHz) on the Ryzen 7 8700G.
Which runs hotter, the Core i7-10700K or the Ryzen 7 8700G?: The Core i7-10700K is rated at 125 W against 65 W, so it produces more heat under load and needs the larger cooler. How hot either one actually runs depends on the cooler and the case more than on the chip.

More comparisons

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.
