Due to the increasingly weak demand in the PC market in recent years, coupled with Intel's focus on squeezing toothpaste for many years, many consumers have clamored for "My XXXX can fight for five years," and XXXX has been named more often with E3. 1230 V1 (including V2, V3) and 2500K CPUs. Among them, the 2500K is representative of Intel's classic SNB architecture. Its architecture is excellent, and its performance is powerful. However, after 2500K has been listed for more than 5 years (actually 5 years), in 5 years, even if Is squeezing toothpaste, it is possible to accumulate quantitative changes, spicy, 2500K in the face of the latest Skylake architecture I5 ​​6600K, after all, can it be a war? Now, let the master of the hustle and bustle lead you to see it together.
Actually, the old U of 2500K is not as good as it was in the hands of the owner. It happened to be the power of the colleague's loom BOOM (a horse power-saving king 600). Let me help him tidy up. While waiting for the arrival of the new power supply, I found that the host of this cargo was actually 2500K U, and I removed it and my 6600K had a lot of inter-age abuse (K).
The two Us are still looking very much like together, but the kernel is already a human being. From the 2500K-6600K experience, not only 32nm-14nm process progress, but also the progress of various architectures, instruction sets, of course, There is also a disdain for the party alone - nuclear progress (no eggs).
On the back, there are only 4 pin gaps between the 1151 and 1155 surfaces, but in fact they are far from perfect. The mountains are always in love. Do you think that Intel Pit is not pitted?
Currently there are 6600K sales, a higher price of East Pack, I am a treasure to buy the film. As for 2500K, a treasure can also be bought on the demolition goods.
The progress of the 2500K-6600K is not merely CPU. The motherboard and chipset advancement is also very large. The Z170 provides 20 PCIE 3.0 buses, supports DDR4 (1.2V) and DDR3L (1.35V) memory, native support up to 3 SATA Express Interface, support M.2 SSD interface, native support USB 3.0 interface.
The following picture shows the ASUS Z170-AR, which was purchased in the hands of the players of the second-hand forum.
In contrast, when the 2500K used the motherboard P67, USB3.0 is not native, SATA3.0 only 2, PCIE bus 2.0, as M.2 Shenma, it is more wood. Of course, the price of the motherboard at that time is still a lot cheaper than it is now, 1000 yuan can buy high-end P67, and now, 1,000 yuan can only buy the mid-level Z170.
The following figure shows the Gigabyte P67A-UD3P B2 version. At that time, 400 oceans were shipped from a certain Bao Tao. At that time, the B3 version had more than 1500. The only drawback of the B2 version was that the four SATA 2.0 interfaces could not be used, only 2 SATA3. 0 interface can be used, but enough for the average player.
Another major advancement is memory. From SNB to Skylake, memory has evolved from DDR3 to DDR4 (although the Z170 also supports DDR3, but that is not the mainstream after all). Compared to DDR3, DDR4 has lower voltage, higher frequency, and higher bandwidth.
On the left side of the figure, the odd-numbered Tritter Z DDR4 3200 8GX2 is on the left and the ten-inch DDR3 1600 4GX2 on the right.
back
Aside from the vests, the DDR4 and DDR3 look no different.
In fact, there is a difference between the two, there is a clear difference between the golden finger, DDR4 gold finger and dense, and both ends are not straight, with a certain degree of curvature, and the DDR3 memory is relatively sparse gold finger, gold finger The PCB at the place is also straight.

Below to start the comparison test, the accessories used for the test are as follows:
The two platforms are ready.
Looking at the workmanship, it looks like the P67 work five years ago is even better.
In addition to the above accessories, other accessories are common, such as graphics cards, MSI's GTX1080 GAMING X 8G.
There is a belief in the back plate.
RGB light of faith.
The radiator is unified to Limin TS120, and other accessories such as power supply have little effect on the performance of the whole machine and are not introduced one by one.
First look at the software screenshots. For SNB and Skylake with K CPU, it is easy to go to 4.5G, so we are all overclocked to 4.5G. For memory, the frequency of the Chichi DDR4 3200 is exactly 2 times that of the Shiyan DDR3 1600. Although the memory frequency difference is not of great impact on the overall performance, when the frequency difference reaches a certain degree, it still has a large performance. Affected.
Start testing, CPU-Z comes with the test software, we can see that the 2500K up to 4.5G not yet high-frequency performance of the 6600K (the figure below is 6600K, the next is 2500K, the following are the same).
Super π, because the software is not sensitive to the instruction set, the gap between the two platforms is not very large.
Chess, 6600K platform more than 2500K 1000 points.
The CINEBENCH R15 and 6600K platforms are more advanced than 2500K.
AIDA 64 memory bandwidth test, we can see, 6600K platform running points are very powerful, high-frequency DDR4 power really extraordinary.
The 3Dmark FireStrike test, whether it is the total score or the physical score, is not a small gap between the two platforms.
3Dmark Time Spy, the gap between the two platforms is still small.
VR test, this seemingly only related to the graphics card, is not very sensitive to the CPU and memory.
Game test, bloody rogue, resolution is set to 1920X1080.
Special effects open to the highest.
As a result of the test, the 2500K platform is nearly 20FPS behind the 6600K platform, and this gap is still quite large.
Killer 5 pardon, resolution set to 1920X1080
Special effects open to the highest.
According to the test results, the 2500K platform lags behind 17FPS on the 6600K platform, and the gap is not small.
The singularity is gray, the resolution is set to 1080, and the effect is turned to full height.
Test results, 79.2FPS to 56.7FPS, 6600K platform burst 2500K platform.
Killer 6, the resolution is set to 1080, the effect is open to full height.
After Killer 6's Benchmark test is completed, the screen is not displayed. Instead, a TXT file is created in the C drive's user folder. All result data is in this file. It can be seen that the game is still the 6500K platform burst 2500K platform.
Tomb Raider 10, resolution set to 1080.
Special effects open to full height.
Finally came a game that is insensitive to CPU and memory performance. The gap between the two platforms of the game is very small, only less than 1 FPS.
Power consumption test, did not expect the standby power consumption of the 2500K platform is also lower than the 6600K platform (it is estimated that the 6600K nuclear significant progress, accounting for the large power consumption), but the gap when baking machine suddenly came out.
Temperature test, in fact, SNB architecture is famous for good overclocking, low temperature (and the top cover and the core is still brazing Oh), but did not expect the use of 6600K between the top cover and the core is better than a silicone link, temperature Lower, it seems that the advantages brought by 14nm are obvious.
The test summary is good and bad, and everyone checks it by themselves, and I don't have to use my mouth.
to sum up:
Because of AMD's incompetence, Intel opened the road to squeeze toothpaste. In spite of this, the quantitative changes accumulated over the past five years are still quite impressive. At the same frequency, the 2500K platform has been far behind the 6600K platform. The statement of “five years of war†has lost its significance. Let's summarize a few more words:
CPU, 2500K-6600K, process upgrade from 32nm to 14nm, the middle of the architecture is separated by five generations, the instruction set has also increased AVX2, FMA3, TSX, etc., by comparison evaluation point of view, the advantages of 6600K to 2500K is obvious, Now a treasure there are second-hand 2500K sale, the price is much lower than the 6600K, but given the 2500K old architecture platform and weak performance, coupled with the supporting motherboard are second-hand foreign waste, quality is not guaranteed, I do not recommend buying.
The main board and chipset, P67-Z170, PCIE 2.0 bus to 3.0, third-party USB3.0 to native USB3.0, third-party SATA3.0 to native SATA3.0, there is no DMI 3.0 bus, M67. 2 interface and so on.
In terms of memory, DDR3-DDR4, lower voltage, higher frequency, and higher bandwidth mean higher performance and lower power consumption. For DDR3, 3000 MHz is at the end, while for DDR4, The show has only just begun. With the progress of the process, DDR4 4000 is not a very difficult task.
In short, a penny, a purchase, buy a new do not buy the old, the so-called "XXXX can fight for five years," the argument, is just a self-deception self-comfortable Bale!
