Intel core i5

Our Verdict

The Core i5-8400 brings a powerful six-core design khổng lồ the mid-range, offering class-leading gaming performance và competitive sầu performance in heavier applications. More expensive sầu models offer more performance in both categories, but the Core i5-8400 is easily the pound-for-pound gaming champion.

There"s no doubt that AMD"s Ryzen processors challenged Intel"s position in the desktop PC market this summer. Seemingly in response (though we all know this stuff is planned way in advance), the Coffee Lake-based Core i7 và i5 CPUs landed with six cores each. That was a first for Intel"s mainstream platform.


The bộ vi xử lý Core i5 series typically offers enthusiasts the best performance for their dollar. But with those two extra cores, Intel"s highest-kết thúc Core i5 is now faster than Chip Core i7-7700K in most games, và even in some applications. This means the Coffee Lake bộ vi xử lý Core i5s basically replace last generation"s Core i7s. Talk about a huge step forward. Now the mid-range chips can backstop top-kết thúc GPUs without becoming bottlenecks.

Like the more expensive sầu Core i5-8600K, Intel"s -8400 features six cores without Hyper-Threading. Aside from its locked multiplier, the key differences boil down to cloông chồng rates, thermal thiết kế power, and price. A 2.8 GHz base frequency is the lowest of all Coffee Lake-based processors, including Intel"s bộ vi xử lý Core i3 models. That"s because the company had to squeeze into the -8400"s 65W TDPhường, while Vi xử lý Core i5-8600K gets a 95W rating, allowing the same silicon lớn accommodate a 3.6 GHz base.

On the surface, a lower cloông xã rate looks bad for performance. But remember that Intel"s Turbo Boost technology accelerates frequencies within certain parameters. This allows the -8400 to lớn go quite a bit faster in workloads that don"t tax all of the -8400"s cores. As you can see in the table above sầu, the 8400"s multi-core Turbo Boost bins get a lot more aggressive sầu than Core i5-7400"s. And they only trail the -8600K by 300 MHz.


bộ vi xử lý Core i5-8400 drops inkhổng lồ a LGA 1551 interface, but as we know from our previous Coffee Lake reviews, it isn"t backward compatible with 200-series motherboards. That means you"ll have sầu to lớn step up lớn a 300-series motherboard, even though that means getting no new features in the process. Worse, a rushed launch means the Z370 chipmix is your only option for now. Cheaper B- & H-series motherboards, which will cost a lot less, arrive sầu at the beginning of next year. The Core i5-8400 is a locked processor anyway, so the reason most enthusiasts would have sầu had for spending extra (overclocking) doesn"t apply here.

Intel cites a $182 recommended customer price, which is the same as its Kaby Lake-based bộ vi xử lý Core i5-7400. That"d be a great value for 1/2 more cores. However, poor supply means that the -8400 is popping in and out of stochồng, selling for as little as $200 when the big shops receive a shipment. When they run out, smaller vendors run the price up closer to lớn $260. That"s Ryzen 5 1600X territory. AMD also has an advantage in that you can plug its Ryzen chips inlớn B350-based motherboards selling for as little as $80. At least the competing models both include bundled coolers; we don"t always get such a luxury in the high-end space, where you"re often expected lớn supply your own thermal solution.
