Intel Core i7-7700K vs AMD Opteron 2352
The Core i7-7700K is the clear pick for a desktop build: it is roughly twice as fast per core, has Hyper-Threading for eight threads, and runs on the common LGA1151 platform. The Opteron 2352 is a 2007-era server chip on the dead Socket F platform, so it only makes sense as a cheap part for an old server board.

What reviewers say
Intel Core i7-7700K
Owners generally rate the i7-7700K as a fast, reliable gaming chip for its generation, with easy overclocking headroom. The common complaints are heat and power draw, especially when overclocked, and its four-core limit in newer multi-threaded software.
- PerformancePraisedOwners call it fast for gaming and everyday use, with strong single-thread speed for its generation.
- OverclockingPraisedThe unlocked multiplier makes it easy to push past 4.2 GHz on a Z270 board.
- HeatCriticisedReviewers and owners report high temperatures, especially once overclocked, and recommend a strong cooler.
Questions and answers
- Which is better for gaming?
- The Core i7-7700K, by a wide margin. Its 4.2 GHz clock and 8 threads handle modern games; the Opteron's 2.1 GHz and 2007 architecture will bottleneck almost any current title.
- Can I use them in the same motherboard?
- No. The i7-7700K needs LGA1151 and the Opteron 2352 needs Socket F. They are not interchangeable and use different memory types.
- Which lasts longer?
- The i7-7700K stays usable for everyday desktop work far longer. The Opteron is already too slow for most current software, so it only lasts as long as the old server board it sits in.
- Is the Opteron worth buying at all?
- Only to revive an existing Socket F server or for a retro build. For any new build, the i7-7700K is the better use of money.
- Do I need a separate cooler for the i7-7700K?
- Yes. It ships without a cooler and its 91 W TDP needs a decent tower air cooler, especially if you overclock.
