My CPU's boost clock is listed as 5,200 MHz in one benchmark tool and 5.2 GHz on the retail box. Which is correct?

Both are correct — same frequency, different notation. 5,200 MHz ÷ 1,000 = 5.2 GHz. Benchmark tools often report in MHz because they query hardware registers that return MHz values; the box uses GHz for consumer readability.

What's faster: 2.4 GHz Wi-Fi or 5 GHz Wi-Fi — and how does the MHz figure help me compare?

5 GHz (5,000 MHz) offers higher theoretical throughput but shorter range. 2.4 GHz (2,400 MHz) penetrates walls better. The MHz values confirm 5 GHz is about 2× higher in frequency, meaning shorter wavelengths that carry more data but attenuate faster through walls.

A processor review lists the memory bus at 3,200 MHz. My system builder quoted 3.2 GHz RAM. Are those the same?

Yes — 3,200 MHz = 3.2 GHz exactly. Divide by 1,000. DDR4 memory speed ratings use MHz universally in practice, so 3,200 MHz RAM and 3.2 GHz RAM are the same product, just written differently.

I'm looking at a Wi-Fi spec that says 5 GHz — how many MHz is that for antenna length calculations?

5 GHz × 1,000 = 5,000 MHz. Antenna designers work in MHz: quarter-wave antenna length = 300 ÷ (4 × frequency in MHz) metres = 300 ÷ 20,000 = 0.015 m = 1.5 cm for 5 GHz. See [MHz to Hz](/frequency/mhz-to-hz/) for converting to Hz for wavelength equations.

MHz = GHz × 1000

Formula

GHz = MHz ÷ 1,000

CPU benchmarks, router spec sheets, and cellular band plans express frequency as GHz for readability, while oscillator datasheets, software configuration fields, and older reference documents often use MHz. A processor running at 3,600 MHz and one rated at 3.6 GHz are the same chip. A Wi-Fi router broadcasting at 2,400 MHz is the same as 2.4 GHz. Dividing MHz by 1,000 brings the value into GHz — the notation that dominates modern consumer and engineering specifications.

Frequently Asked Questions

Real-World Examples

Wi-Fi 2.4 GHz band. Most home routers broadcast here; this 802.11b/g/n band travels farther than 5 GHz but shares spectrum with microwave ovens and Bluetooth.

2400 MHz = 2.4 GHz

Mid-range desktop CPU base clock. A processor listed as 3,600 MHz in a benchmark spreadsheet is the same 3.6 GHz chip shown in the retailer's spec sheet.

3600 MHz = 3.6 GHz

Wi-Fi 5 GHz band (802.11ac/Wi-Fi 5). Higher throughput at shorter range — ideal for video streaming within the same room as the router.

5000 MHz = 5 GHz

CPU boost/turbo clock for high-performance desktop processors. Chips that list 5,200 MHz boost in reviews are the same as the '5.2 GHz turbo' on the box.
