AMD Ryzen 5 240 vs AMD Ryzen 5 8645HS

On the specifications we can verify, the AMD Ryzen 5 240 and the AMD Ryzen 5 8645HS are closely matched. Which one is faster on your desk depends on cooling and sustained behaviour rather than on anything printed here.

Not verified

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.

Power and cooling

The Ryzen 5 240 is rated at 54 W against 45 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. In a laptop the maker chooses the real limit inside a range, so the same chip can behave like two different processors in two machines. That spread is what a sustained test measures and a specification sheet cannot. 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

Laptop processors are soldered to the board, so this is a choice between machines, not between chips you can swap. What differs between two laptops with these parts is mostly the power limit and the cooling the maker gave each one.

Which to pick, on paper

A quiet or compact build: Ryzen 5 8645HS; 45 W against 54 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 Ryzen 5 240 better than the Ryzen 5 8645HS?: By need, on the specifications: a quiet or compact build: the Ryzen 5 8645HS. 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 Ryzen 5 240 and the Ryzen 5 8645HS use the same socket?: Laptop processors are soldered in place, so neither can be swapped for the other.
Does the Ryzen 5 240 or the Ryzen 5 8645HS have integrated graphics?: Both do: AMD Radeon 760M Graphics on the Ryzen 5 240 and AMD Radeon 760M on the Ryzen 5 8645HS.
Which runs hotter, the Ryzen 5 240 or the Ryzen 5 8645HS?: The Ryzen 5 240 is rated at 54 W against 45 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.
