Is it 8+4 core strength or 12 core strength? Intel Core i7 12700K first review

As we all know, Intel is equipped with a hybrid architecture on the 12th generation, the performance core is Golden Cove, the performance core is Gracemont, and the configuration of the protagonist 12700K in this article is 8+4. Coincidentally, AMD has a product with the same 12 cores. , 5900X, today we will let them compete. The 12700K used in this article is the QS qualified sample version, and the step is C0, which is consistent with the official version. Since ADL is on the replacement node of DDR5 and DDR4, this test will test DDR5 and DDR4 at the same time, and at the same time need to compare AMD's products with the same positioning, so in order not to make the data too large, this test will be split into i5 , i7, i9 each. Appearance display ▲First of all, let's take a look at the real body of the CPU. Because the number of pins has become more, the size of the previous CPU is definitely not enough, so this time the CPU has become a lot slender. ▲The triangle that confirms the direction is directly printed on the top cover of the CPU, which is still very clear. CPU Specifications ▲ The 12700K adopts a configuration of eight performance cores (P cores) + four energy efficiency cores (E cores), with a total of 12 cores, sharing the L3 25M large cache, the maximum main frequency is 5.0G, and the full-core turbo frequency is 4.7G. However, since only the performance core supports hyper-threading technology, this processor has only 20 threads, which is slightly inferior to the 5900X of the full-performance core. This time it is finally not the ancestral 14nm. It came to the Intel 7 process in one breath, which is the 10nm ESF process. Yes, Intel has also started to play digital games, but this cannot be blamed on Intel, after all, the next door started shameless. The PCIe channel of the CPU has also been upgraded to PCIe 5, which doubles the bandwidth again compared to PCIe 4. In addition to the PCIe 5 x16 of the graphics card, it also provides M.2 PCIe 4 x4, for a total of 20 PCIe. This CPU maintains the 125W TDP of the previous generation K series, and it seems that it is not destined to be a fuel-efficient lamp. On-machine test▲This test is not sponsored by Intel. All CPUs are purchased at their own expense through special channels, including one for 12900K QS official version, one for 12600K QS official version, one for 12700K QS, and one for 12400 QS. The cost is more than 2W yuan, please give it a thumbs up and go. ▲First of all, according to international practice, let's take a look at the hardware used in this test. ▲The motherboard is from ASUS' ROG Maximus Z690 Hero. ▲ The CPU base is still LGA, but it has grown a lot, with a total of 1700 pins. ▲ADL is compatible with both DDR4 and DDR5, so you will see that the Z690 has both DDR4 and DDR5 boards, but this time the pure-blooded ROG series only has DDR5, and the position of the gap has also changed slightly, so they are not compatible with each other, the voltage step down to 1.1V, and the 5V to 1.1V step-down is done by the memory itself. ▲ The eyes of the prodigal! Pixel version? ▲ The graphics card uses ASRock's Radeon RX 6800XT Taichi. ▲The memory comes from Jintigo's DDR5 Speed ​​Tiger 16Gx2, and this group of specifications is 4800 C40-40-40-76. As for why you want to use this set, because it is the first DDR5 memory to be sold and shipped, no one can sponsor it and you can only buy it yourself. The total cost of two pieces is 2000 RMB. ▲The choice of radiator is the overclocked Sanling mirror GI-CX360 white. ▲The body adopts a pure white design. ▲The front of the cold head is a diffuser, on which you can clearly see the LOGO of PCcooler. The diffuser can be freely rotated 360 degrees, and can be installed in various angles, keeping the LOGO always facing the user at all times. The cold pump adopts graphite bearing and ceramic shaft core, which can effectively reduce the noise generated when the pump rotates at high speed and improve the life of the pump. ▲The copper bottom has a protective film when it leaves the factory. After tearing it off, you can see the copper bottom. This CNC high thermal conductivity pure copper bottom can ensure a faster heat conduction speed. ▲The three 12cm fans are all nine blades, which can effectively increase the air volume, and the overall air volume can reach 72CFM. ▲The silicone grease is GT-3 with overclocking three. ▲The thermal conductivity of silicone grease is 12.8W/(m*k), so only 2 grams is enough for three times. ▲The power supply is Antec’s HCG-X1000, which provides a ten-year renewal service. There is still a big gap between the ten-year renewal and the ten-year warranty. Compared with its own HCG series, HCG-X can provide better electrical performance and improve computer stability. A larger fan can further reduce the air volume and reduce the noise caused by the fan speed. ▲The local tyrant gold frosted color matching is the biggest reason for me to buy it. Although there is no performance improvement, it will make your computer higher. ▲The power of a single channel of 12V can reach 996W, and the overall maximum power can reach 1000W, supplemented by 80 PLUS gold certification, which can be described as one of the high-end must-haves. Theoretical performance test First explain the hardware parameters used in this test. DDR4: 3600MHz C16-16-16-36, Intel Gear 1 mode, AMD FCLK 1800MHz. DDR5: 4800MHz C40-40-40-76, Intel Gear 2 mode. AMD processors have PBO turned on all the time. AMD uses Windows 10 21H1 operating system, Intel RKL, ADL uses Windows 11 21H2 operating system. The AMD motherboard is ASRock X570 Taichi Razer, and the Z690 DDR4 motherboard used by the 12900K is currently in a state of confidentiality, so it is not convenient to show. Since the current Windows 10 21H1 has scheduling problems for the hybrid architecture, a set of pure P core tests with small cores turned off under Windows 10 21H1 are added to provide a reference for students who do not want to install Windows 11. ▲Cinebench R20 benchmark test, run three laps to take the average, the results are shown in the figure. ▲Cinebench R23 benchmark test, run three laps to take the average, the results are shown in the figure. ▲ The 3DMark TS of the DX12 2K game performance test, run three laps to take the average, the results are shown in the figure. ▲ The 3DMark TSE of the DX12 4K game performance test, run three laps to take the average, the results are shown in the figure. ▲ The 3DMark FSE of the DX11 4K game performance test, run three laps to take the average, the results are shown in the figure. ▲3DMark CPU Profile pure CPU benchmark test, run three laps to take the average, the results are shown in the figure. ▲CPU-Z 17.01.64 SSE test, run three laps to take the average, the results are shown in the figure. Temperature, power consumption, memory delay test ▲AIDA64 uses the built-in memory delay test, and the average is obtained by testing three times. The results are shown in the figure. Game performance test ▲CSGO manual full-height special effects, use the FPS Benchmark Demo of the creative workshop to test three laps to take the average, the results are shown in the figure. ▲Far Cry 6 presets the highest image quality, and uses the built-in Demo test to take the average of three laps, and the results are shown in the figure. ▲Tomb Raider: Shadow DX12 defaults to the highest quality, and uses the built-in Demo to test three times to take the average. The results are shown in the figure. ▲Watchdog: Legion presets the highest image quality, and uses the built-in Demo to test three laps to take the average. The results are shown in the figure. ▲Forza Motorsport: Horizon 4 presets the highest image quality, unlocks the frame rate and closes it, and uses the built-in Demo to test three laps to take the average. The results are shown in the figure. ▲Rainbow Six: Siege presets the highest quality, 100% rendering, and uses the built-in Demo test to take the average of three laps. The results are shown in the figure. In conclusion, although the 12700K has 4 fewer threads than the 5900X, it is enough to turn the 5900X. With the newly designed Golden Cove micro-architecture, supplemented by a very high frequency, the 12700K has achieved good results in both single-core and multi-core. score. The burn-in power consumption of less than 180W allows a 240 AIO water cooling to easily cope with it, and even the mid-to-high-end split cooling can achieve a good temperature performance, which is far ahead of the heat-accumulating AMD. . The game performance is also fully crushed by the 5900X, and the 12700K can lead the 5900X by more than 30% in some CPU-biased games, which can be said to be very scary. Next, let’s talk about the purchase recommendation, the direct brainless 12700K+DDR4, the current price of 5900X is not attractive enough, the price of JD 3999 is a bit high, the current 12700K pre-sale for 3199 really has no reason not to choose, burn-in power consumption If it is less than 180W, choosing an entry-level Z690 with SPS MOS will not be much more expensive. At present, there are two Z690s whose prices have not yet come out. According to the power consumption, a 12700K with a motherboard of about 1200 is completely sufficient. DDR4 is still recommended for the memory part. Although DDR5 has better playability, it can only get higher overclocking space with 12900K.
