Intel Core i5-9400F CPU Review: Cutting On-Die Graphics For A Slightly Lower Price

[harlan4096]

Our Verdict

The Core i5-9400F represents the most iterative updates possible, yet it clings to the mid-range gaming crown. But the -9400F’s lack of Hyper-Threading and a locked multiplier allows the Ryzen 5 2600X to rise up as a more attractive option when we look at all-around utility in this price range.

For

Leading game performance
Discounted price compared to vanilla Core i5-9400
Flimsy bundled cooler is better than nothing

Against

Disabled graphics
Locked ratio multiplier
Big price-to-performance disadvantage compared to AMD in threaded workloads

A Moderate Refresh

Intel announced its Core i5-9400 processors in January, but the chips only recently become available in significant quantities. The company also rolled out the rest of its Coffee Lake refresh models, six months after its initial salvo, a delay likely attributable to its ongoing 14nm production shortage.

As Intel struggles to satisfy demand for its chips, AMD has launched its Ryzen 3000-series processors. The updated Ryzen line-up employs a smaller 7nm process that should confer power and price benefits. It'll also wield the new Zen 2 microarchitecture, which is expected to boost performance while Intel remains mired in a derivative of the seven-year-old Skylake design. These chips have now taken our Best CPUs list by storm, so be sure to head there for a list of the latest leading processors.

Intel's lingering lack of 14nm capacity reverberates through every facet of the industry. To boost supply, the chip-maker decided to start selling CPUs that it would have otherwise deemed defective due to nonfunctional graphics units. As a result, we now have the F-series, which includes disabled graphics hardware, but is otherwise identical to the fully-featured Core processors we're more accustomed to.

That means the Core i5-9400F is nearly identical to the Core i5-9400. Both CPUs serve to replace the impressive Core i5-8400, which was one of the most popular Coffee Lake models. Armed with 6C/6T and a slightly higher clock rate, the 9400s yield an incremental step forward over their predecessor.

Moreover, we're finally seeing the F-series' lower price kick in. The Core i5-9400F's ~$20 discount could be compelling for mid-range gamers who don't need integrated graphics.

Core i5-9400F and Core i5-9400

From an architectural standpoint, the Core i5-9400 and -9400F are essentially the same processor as the Core i5-8400, right down to their 14nm++ process, six physical cores, support for dual-channel DDR4-2666, and 65W TDP. The CPUs also drop into an LGA 1551 interface, and they are supported by existing 300-series motherboards with up-to-date BIOSes. They're multipler-locked, unfortunately, so they include Intel's flimsy stock cooling solution.

Again, the Core i5-9400F lacks integrated graphics, which isn't an issue for gamers who already use add-in GPUs. However, we find it interesting that Intel maintains the same $182 recommended price as its standard Core i5-9400.
