AMD released the 32nd-core, 64-thread second-generation Threadripper processor today. The Q3 quarter went on sale. Both the number of cores and the progress exceeded the 28-core processors Intel demonstrated yesterday. However, Intel did not catch up with AMD. The nuclear processor can go up to 5GHz frequency, and in the all-core state, the Threadripper processor frequency must not catch up.
However, Intel's 5GHz is not so easy. It uses the expensive LGA3467 platform and is a special heat sink.
Since releasing this article yesterday, the first reaction of most readers is that the 28-core 5GHz power consumption must not explode.
This is indeed a problem for Intel. The 6-core Core i7-8700K is already hot enough at full speed (or overclocking at 5GHz). It can be confusing to run 5GHz at 28 cores. After all, it is still 14nm. Intel is not. May use a new process to reduce power consumption and heat.
Regarding this issue, other media counterparts are puzzled. Foreign media such as Anandtech and Tomshardwar have the opportunity to see Intel’s 5GHz 28-core platform on the ground after the speech. This tells a lot of secrets. Let's take a look at what the Anandtech website says.
First of all, Intel's 5GHz frequency does not flicker, in the CINBENCH R15 test did achieve the full core 5GHz, multi-core score 7334 points.
Intel now has a 28-core, 56-thread Xeon Platium 8180 processor, with an R15 score of around 5,040 minutes at 3.34GHz and a 5GHz score of 7560 points. It is very close to the score that comes out of the field. It can be viewed as an error. Intel is now using the Xeon Platium 8180 overclocked version.
The Xeon Platium 8180 uses the LGA3467 slot. There are Asus and Gigabyte motherboards on the site. You can see that the slot is quite large, but Intel's 28-core processor is for consumer-grade, so this motherboard will also appear on the consumer-grade motherboard. .
The original mentions that Intel launched the Skull Trail dual CPU platform 10 years ago. The motherboard can use two QX9775 processors. However, this platform is very expensive and the number is small.
As for the power consumption issue, some of our readers have previously cited 18-core Core i7-7980XE processors with power consumption of up to 1000W, and the original readers have estimated power consumption from 300W to 1000W.
This 28-core processor is not an ordinary CPU. Overclocking at 5GHz does cause overheating. Anandtech believes that there are two possibilities for heat dissipation: water cooling or phase change cooling. However, the latter will cause frost around the slots, freezing, and the site is very clean. , so this system will be water cooled.
In general, the water cooler can achieve 1500W thermal performance, medium-sized can also achieve 500-800W thermal performance, spend at least hundreds of dollars.
Then Anandtech confirmed that Intel used a Hailea HC-1000B compressor with an hourly flow rate of 1500-4000 liters, and used R124 water coolant to reduce the water temperature to about 4°C. The cooling power was 1770W, using a Corsair AX1600i power supply.
There is frequency, Intel said it is 5GHz frequency, it shows 5GHz full-core operation, Intel did not say that it is overclocked, but most people think it is.
The Xeon Platium 8180 itself is a 2.5GHz base frequency, 3.8GHz core frequency, 3.2GHz full-core frequency, even if Intel's 28-core processor is the base frequency of 3.0GHz, 4.0GHz acceleration frequency, there is still a lot of overclocking space.
Finally, the price, Xeon Platium 8180's price reached 10,000 US dollars, although consumer-grade 28-core processors will be escaping features such as ECC memory support, Intel still have to be alert to the market for this processor.
In addition, in addition to the processor, motherboards that meet this processor are also expensive, the memory is 6 channels, requires 6 8GB DDR4-2666, which also increases the cost of 1000 US dollars, this system will be easy Open 10K is a ten thousand dollar level.
For high-end enthusiasts, they may spend $100,000 or more on custom water cooling systems.
