Intel Core i5 8400 - Pros & Cons

cheaper price than the i5-8400 and great all around performance
the new Core i5 is better than ever
a new processor and architecture improvements
stellar performer and a great value
enthusiasts the best performance for their dollar
in-depth reviews and helpful tips
the best CPU on the market for gaming and general productivity

doesn't exactly push a modern CPU to its limits
it lacks an in-box cooler
Intel has long been conservative with its rated RAM support
chips were a bit slower when it came to lightly threaded tasks
the only new chips Intel is rolling out in this update
there is no option for backwards compatibility
will only function within the confines of a 300-series chipset
Ryzen processors have closed the gap considerably in terms of gaming
overclocking gives you no extra gaming performance
seventh generation CPUs do not work in motherboards designed
less expensive
isn't backward compatible with 200-series motherboards
have charts based on FPS or seconds or related to MSRP
a lower clock rate looks bad for performance
lack of Hyper Threading support
gaming performance is still a bit of a difficult undertaking
little lace
leather
and a fiery attitude
the 8400 is not nearly as impressive
there is a direct connection between the motion inputs required
punctuation is not allowed except for periods
hyphens
apostrophes
losing or winning
they always have a high kill percentage and
Its clock speeds may be rather restrained
memory is much lower - generally just three per cent or thereabouts
cutting hyper-threading and reducing clocks
lack of eight-gen compatibility
older chips will not run on this platform
typically more expensive and only enables overclocking for unlocked parts
AMD was a bit cheeky and somewhat annoying
can't be overclocked and lacks HyperThreading
cost/performance equation is still skewed toward AMD
with six cores and does not support Hyper Threading

5.0

The Core i5-8400 is Intel's most affordable option to go beyond a quad-core setup on the desktop. With a price point of $190, it is only half the price of Core i7-8700K, but delivers nearly the same performance in games and can also compete with the Ryzen 6c12t processors thanks to its good single-threaded performance and high boost clock.

Intel's six-core "Coffee Lake" Core i5 trades blows away much pricier previous-generation Core i7 chips. But it's most impressive when paired with a dedicated graphics card.
