2025年9月8日 | admin | C3

Intel’s ninth-generation Core has now begun to spread out gradually, and it has launched a comprehensive fight with AMD’s Ruilong.

The performance is quite powerful, but the corresponding power consumption and price are also amazing, soRelatively speaking, many students will pay more attention to the i7-9700K. After all, it is more balanced in terms of specifications, performance and price.

Today, I will bring the test report of the first i7 processor without hyper-threading technology.

Description of product specifications: The appearance of i7-9700K is exactly the same as that of i9-9900K, so I won’t repeat it here. Here is a brief look at the product specifications.

Compared with i9-9900K, the obvious difference is that the core scale has changed from 8 cores and 16 threads to 8 cores and 8 threads, and the hyper-threading technology has been cancelled. In fact, except i9-9900K, all the nine generations of Core have no hyper-threading.

The core frequency drops slightly,The dual-core turbo frequency is 4.9GHz and the full-core turbo frequency is 4.6GHz.

There are five expansion slots on the motherboard, which are arranged as X1X16NAX1X8NAX4 according to the PCI location, among which the slots of PCI-EX1 are all designed with notches, which can be compatible with high-bandwidth PCI-E expansion cards, such as SATA cards of PCI-E X4.

Cut the hyperthreading! Intel i7-9700K in-depth evaluation: drawing R7 is just too expensive.

There are three M.2 SSD expansion slots on the motherboard, all of which can support PCI-E X4 and SATA channels. However, the slots on the left (M2_1) and the right (M2_3) in the figure occupy two SATA interfaces, which are mutually exclusive. The slot in the middle (M2_2) will eat a SATA interface when using the SSD of SATA channel. The M2_3 slot of the motherboard is covered with a metal heat sink.

At the bottom of the motherboard is a row of expansion slots. From the chipset side, from right to left, they are SYS FAN, chassis front control pin, BIOS test pin, BIOS cleaning pin, 80 debug lamp, front USB 2.0 and front USB 2.0 (single interface 4PIN). The single-port USB 2.0 pin is a bit strange. This interface is because a USB 2.0 was eaten by wireless Bluetooth, so the general motherboard will not let go directly, because the wires of the chassis are now in groups of two. It’s ok to control the cold headlight group inside the chassis.

There is also an ASM1184 chip on the motherboard, which is used to switch PCI-E channels and bridge one PCI-E 3.0 into four PCI-E2.0. Generally speaking, the design ideas of Huaqing and Gigabyte Asustek are quite different. Asustek Gigabyte prefers to use a lot of SWITCH switching and speed reduction to solve the problem of insufficient chipset channels. Huaqing, on the other hand, prefers to use more HUB chips for switching, so as to minimize the loss of PCI-E bandwidth. However, the cost is also obvious. More chips reduce the integration of the motherboard.

Performance test and analysis of CPU;

The system bandwidth test shows that the system bandwidth i9-9700K has been further improved, slightly lower than i9-9900K. Compared with i7-8700K, the improvement is mainly concentrated on L1 and L2, especially the bandwidth of L1 is increased by 40%. There is also a 10% improvement in the delay of L1L2.

CPU performance test mainly tests some commonly used CPU benchmark software, and also includes some application software and CPU test items in the game. In this part, i7-9700K mainly has advantages in single-threaded testing, and can be close to i9-9900K. However, multithreading performance is relatively general, and some tests are not even as good as i7-8700K.

Set display performance test:

The theoretical performance test of centralized display is carried out with the built-in tools of AIDA64. Due to the compatibility problem between Intel’s integrated display driver and WIN10 of 1709, i7-9700K did not collect data for integrated display 3D benchmark test, and mainly ran some benchmark test software.

There has always been a big controversy about the resolution in game testing, so I’ll break it down directly here. Because DX11 games account for more than half of my testing, it seems that i7-9700K will be slightly weaker than i9-9900K at both resolutions, but it will be significantly stronger than R7 2700X at 1080P.

Summary of test results:

The comparison groups in this test are i9-9900X, R7 2700X, i7-8700K and R5 2600X. All products are close to the current positioning or price of i7-9700K.

Because the performance test environment of CPU has been changing dynamically (system, BIOS, driver), i9-9900K, i7-8700K and R7 2700X have been tested completely. The testing time of R5 2600X is in April 2018.

AMD RYZEN has undergone some changes after updating the BIOS and drivers. The problem of memory copy performance degradation found in the initial test of B450 has been fixed, but at the cost of CPU power consumption increase and NVME disk performance decline. Therefore, it can be confirmed that AMD’s microcode in 1.0.0.4 recently corrected some Spectre vulnerabilities. Overall, the CPU performance is basically unchanged (increased by 0.5%), and the NVMe performance is reduced by 5%. In the release test, the problem of current limiting of R7 2700X baking machine has also been solved, so the power consumption of R7 2700X will be revised and increased by about 15%.

As far as the performance of CPU is concerned, it is quite interesting.After synthesizing various usage scenarios, the i7-9700K and R7 2700X are on a par. Relatively speaking, the single-threaded performance of i7-9700K is more advantageous, while the multi-threaded performance of R7 2700X is more advantageous.

As far as the performance of Jixian is concerned, there is nothing to say because Jixian has not been updated.

With the unique part, the i7-9700K has become the strongest one without any accident, but it has not opened the decisive gap.

In terms of power consumption,I7-9700K is more balanced, a little higher than i7-8700K, and there will be no out-of-control situation like i9-9900K.

Finally, the last horizontal comparison table is for your reference.

The performance part only compares the test items related to CPU, and does not include the results of the game performance test. Because the graphics card has been changed in the middle and the memory frequency has changed to some extent, this table can only be used for general reference for the time being. In the table, the results of previous tests (different graphics cards) are not included, and only the test results that are not affected by the graphics card are extracted. In the horizontal test, it is found that R7 2700X is slightly higher than i7-9700K. This is because the benchmark in the previous test is i7-8700K, and the reference benchmark in the horizontal test is i7-7700K all the time, so the CPU with a particularly close performance gap will be affected by the benchmark change, and its ranking will change.

Simple summary:

About CPU performance:

As far as CPU performance is concerned, i7-9700K is quite good by itself. Single-thread performance ensures the fluency of daily software use, and multi-thread performance reaches the level of i7-8700K.

On the performance of centralized display:

The display of i7-9700K has not been updated, so there is no change. With regard to the unique display: In the case of unique display, i7-9700K and i9-9900K are quite close, and they sit firmly in the first group, but relatively speaking, the influence of CPU on game performance is really not great, and there is no substantial difference above six cores.

About power consumption:

The power consumption control of i7-9700K is quite reasonable, even if the FPU is baked alone, it will not roll over. It seems that high frequency+hyper-threading is a poison to AVX instruction set. Accordingly, the B360 motherboard with solid power supply can be considered in the matching of i7-9700K, which can greatly reduce the budget of the whole machine. The motherboard suggests that the power supply of the CPU core should be greater than or equal to 6 phases.

About overclocking:

Because the power consumption control of i7-9700K is much better than that of i9-9900K, it should be easier to achieve super 5G.

Generally speaking, the performance of i7-9700K is relatively excellent, both single-threaded and multi-threaded. However, compared with other products in the market, the biggest embarrassment is that it can’t open the gap with R7 2700X, but there is a big gap in price. The boxed price difference in JD.COM exceeds that in 1000 yuan.

I7-9700K and R7 2700X are just two CPU optimization directions, i7-9700K has advantages in single thread, R7 2700X has advantages in multi-thread, and the two on the other end are also completely qualified, so in the use scenarios of these two CPUs, single-thread performance will be more important. If the price difference between i7-9700K and R7 2700X is below 15%, then i7-9700K will have obvious purchase value.
