Packaging, scope of delivery and appearance

To us for testing the processor Intel Core The i5-7400 arrived in a boxed version with colorful cardboard packaging. On its sides you can find not only key features novelties, but also some technical characteristics.

The delivery set is quite familiar. It includes a paper user manual and a stock cooling system.

Externally, the Intel Core i5-7400 is no different from other representatives Intel series Kaby Lake. The front side is almost completely covered by a heat-distributing cover, which protects the crystal from chipping during mounting and dismantling of the cooling system, and is also the first stage in the cooling system. It lists the CPU model, Spec code, nominal clock speed, and FPO code. The latter allows you to find out that the novelty was made in Malaysia on the 37th week of 2016. On reverse side there are contact pads for the Socket LGA1151 connector. Recall that motherboards based Intel chipsets 100 series support CPU line Intel Kaby Lake just after BIOS updates. But models based on Intel 200-series chipsets do not require such manipulations and immediately offer to start working with new products.

Reference cooling system

The standard cooling system is a familiar compact design, which consists of an aluminum radiator, on the base of which a thermal interface is already applied, and a small 2.16 W (12 V at 0.18 A) axial 7-blade fan from NIDEC. A 4-pin connector is used for power supply, so the speed of rotation of the blades can be adjusted using the PWM method.

Analysis of technical characteristics

At maximum load, created using the LinX 0.6.5 benchmark, the clock speed of the Intel Core i5-7400 processor rises to 3.3 GHz at a voltage of 1.056 V. If you reduce the load, you can get the declared 3.5 GHz at a voltage of 0.688 V.

For comparison, we recall that the predecessor in the face in similar modes functioned at frequencies of 3.1 and 3.3 GHz and voltages of 1.158 and 1.12 V, respectively. That is, not only an increase in operating speeds, but also a decrease in stresses are already striking.

In power-saving mode, both CPUs drop frequencies to 800 MHz, but in this case, the operating voltage of the predecessor is slightly lower: 0.734 versus 0.816 V.

The organization of the cache memory in the Intel Core i5-7400 also did not become a revelation. We still have the following structure:

• 32 KB of L1 cache per core with 8 associativity channels is reserved for instructions and the same amount for data;
• 256 KB L2 cache per core with 4 associativity channels;
• 6 MB shared L3 cache with 12 associativity channels.

Integrated controller random access memory guaranteed to support dual-channel operation of DDR4-2400 MHz and DDR3L-1600 MHz modules with voltages up to 1.35 V. Intel does not recommend installing brackets with a higher operating voltage. The maximum available RAM is 64 GB.

The integrated graphics adapter is the Intel HD Graphics 630, based on the Intel Gen9.5 microarchitecture. The number of computing units (EU) in it reaches 24. The base frequency of its operation is 350 MHz, and the dynamic frequency can be increased up to 1000 MHz. Intel HD Graphics 630 supports current APIs (such as DirectX 12 and OpenGL 4.4) and up to three displays. For its needs, it can use the entire supported amount of RAM.

Under stress load iGPU its frequency really rose to 1000 MHz. The temperature rose to 35°C (bench cooler was used), and the power consumption reached 13 watts.

Simultaneous loading of processor and graphics cores did not cause any problems. The former operated at 3.3 GHz and the latter at 1.0 GHz. CPU temperature did not exceed 50°C, and power consumption - 46 watts.

As for the critical temperature for the Intel Core i5-7400, on the official page (T junction) and in the AIDA64 utility (T jmax) we saw the same figures - 100°C.

Testing tools and methodology

For a more visual comparison of processors, all games used as test applications were launched at a resolution of 1680x1050.

The built-in benchmarks, FRAPS 3.5.9 Build 15586 and AutoHotkey v1.0.48.05 utilities were used as performance measurement tools. List of gaming applications:

• Assassin's Creed 3 (Boston Port).
• Batman Arkham City (Benchmark).
• Borderlands 2 (Benchmark).
• Call of Duty: Black Ops 2 (Angola).
• Dragon Age Origins (Ostagar).
• Far Cry 3 (Chapter 2. Hunter).
• Formula 1 2012 (Benchmark).
• Hard Reset (Benchmark).
• Hitman: Absolution (Benchmark).
• Just Cause 2 (Concrete jungle).
• Medal of Honor: Warfighter (Somalia).
• Prototype 2 (Resurrection).
• Resident Evil 5 (Benchmark - Scene 2).
• Sleeping Dogs (Benchmark).
• The Elder Scrolls V: Skyrim (Solitude).
• World of Tanks (Mines).

In all games measured minimal And medium FPS values. In tests in which there was no possibility of measuring minimum FPS, this value was measured by the FRAPS utility. vsync disabled during testing.

To avoid errors and minimize measurement errors, all tests were performed three to five times. When calculating the average FPS, the final result was taken as the arithmetic mean of the results of all runs (three not “idle”). As the minimum FPS, the minimum value of the indicator based on the results of three runs was chosen.

Processor Specifications

Reference information for AMD and Intel processors, as well as AMD and NVIDIA graphics cards.

Processor overclocking

The processors were overclocked as follows. The stability of overclocking was checked by the utility OCST 3.1.0 "Perestroika" by running the CPU for half an hour on the maximum matrix with a forced 100% load. I agree that the overclocking of the tested CPUs is not absolutely stable, but for any modern game it is one hundred percent suitable.

At maximum acceleration, all AMD processors the memory controller frequency was raised to 2400-2800 MHz.
