Intel Core i5-7400 Review

                         

The Intel Core i5-7400 basically is a 64-bit quad-core mid-range performance desktop microprocessor that was introduced in early 2017 by the Intel Company. It is a chip that is based on the Kaby Lake microarchitecture and is fabricated on the Intel’s 14nm+ process

Having four cores as well as 3.5 GHz maximum clock speed, the i5-7400 review proves that this is the most basic processor amongst the new Core i5 seventh generation series. It also supports up to 64 GiB of dual-channel non-ECC DDR4-2400 memory and incorporates Intel’s HD Graphics 630 IGP operating at 350 MHz with a burst frequency of 1 GHz.

The i5-7400 is a bit pricier as it has four cores and L3 cache but is locked at a base clock frequency of 3 GHz with a maximum single core operating frequency of 3.5 GHz. In this Intel Core i5 7400 review, the core i3-7350K clocks at least 20% higher and 40% higher when compared to the i5’s clock frequency.

With the Intel Core i5-7350 having a clock speed advantage of about 40 to 60% with its support for Hyper-Threading it is in a good position to challenge the Intel Core i5-7400 although it lacks required threshold to do that.

Performance

The Intel Core i5-7400 features 3.0 GHz base clock, 3.5 GHz turbo clock, 6 MiB of L3 Smart Cache, TDP of 65 W and locked multiplier. It is manufactured under 14nm process. The seventh generation Core I processors like the i5-7400 basically are few improvements to the sixth generation ones. They feature new video decoder for 4K video, improved speed shift technology and support to Optane technology which reflects a future kind of high performance SSDs.

In addition, the Intel Core i5-7400 has 4 threads with a bus speed of 8 GT/s DMI3, 64 GB max memory size (dependent on memory type) and 2 memory channels.

Features an chipset

When we compare the chipset and features in the Intel Core i5 7400 review, users can the most out of the core i5-7400 on a $50 H110 motherboard together with the standard Intel box cooler. On the other hand, the Intel Core 7350K will demand a Z-series motherboard. While Z170 boards start at $90, Z270-based models start at $110. The Intel Core 7350k requires an aftermarket cooler meaning the user will have to add another $30.

This therefore implies that for an entry level motherboard of the Intel Core i5-7400 you will require $250 and at least $300 for the basic Z170 board and budget tower style air-cooler for the Intel Core i5-7350K processor.

Overclocking and heat

The Intel Core i5-7400 processor reviews shows that it has a Thermal Design Power (TDP) of 65 W and locked multiplier. It features MMX, EMMX (extended) and supports a Turbo Boost frequency of 3.5 GHz. The multiplicator of the Intel Core i5-7400 is locked and unless you have an expensive gaming mainboard, this processor is limited with permitted power target, system bus speed, turbo clock settings and temperature.

Due to this, the user has to modify the Turbo settings of the CPU in a small degree. The Turbo clocks itself higher when all cores are not in use

Pricing and availability

The pricing and availability of Intel Core i5-7400 reviewed features a $180 retail price which is slightly below Intel Core i5-7350K that is priced at $200 retail price. It becomes quite difficult to choose between the two as they cost the same price in certain countries and their performance is almost similar to each other. The difference is that the Intel Core i5-7400 has four cores and larger L3 cache although it is locked at a base clock frequency of 3 GHz. It also features a maximum single core operating frequency of 3.5 GHz. The direct competitor of the Core i5-7400 in terms of price seems to be the Ryzen 5 1500X.

Conclusion

In the overall review of the Intel Core i5 7400, we can conclude that this processor is an excellent choice as it is affordable. It also features four cores and larger L3 cache even though it is locked at a base clock frequency of 3 GHz. The Intel Core i5-67400 on the other hand is an excellent choice for a low-cost gaming computer as it is much similar to the Ryzen 51600X in the gaming test and is much expensive.
