Intel Core i3-530 vs Intel Core i3-540
On the specifications we can verify, the Intel Core i3-530 and the Intel Core i3-540 are closely matched. Which one is faster on your desk depends on cooling and sustained behaviour rather than on anything printed here.

Platform
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.
The same generation
Both are Intel parts, so their figures can be read against each other directly: the same kind of core, the same memory support, the same platform. The differences in the table are the whole difference.
Power and cooling
Both are rated at 73 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
Both use the FCLGA1156 socket, so one can replace the other on the same motherboard. Check the board maker's support list first: an older board often needs a firmware update before it recognises a newer chip.
Which to pick, on paper
- Upgrading without a new motherboard
- Either
- Same FCLGA1156 socket. Update the board's firmware before swapping.
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 i3-530 better than the Core i3-540?
- By need, on the specifications: upgrading without a new motherboard: either. 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 i3-530 and the Core i3-540 use the same socket?
- Yes, both use FCLGA1156, so either fits the other's motherboard. Check the board's support list and update its firmware first.

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.
