AMD, Intel "Nuclear Warfare" kicked off, 28-core, 32-core desktop CPUs arrived

At the Taipei Computer Show keynote, Intel unexpectedly announced the existence of 28-core desktop processors.The site also demonstrated the test of CINBENCH R15, which can run 28 cores at full speed at 5GHz.. This move shocked the world, to know that the current Intel consumer processor up to only 18 core, full-core Rui frequency only 3.4GHz.

Only one day later, AMD announced its announcement at the June 6 conference.Second-generation Threadripper processor, 12nm LP process, Zen+ architecture, while the number of cores has increased to 32 cores and 64 threads, surpassing Intel's 28-core 56-thread processor shown on the previous dayBecome the new king of desktop processors.

The number of processor cores has suddenly increased to 28-32 cores. In addition to a significant increase in performance, TDP power consumption has also been accompanied.AMD's 32-core processor TDP power consumption reached 250W, Intel's 28-core processor will require 300W TDP, CPU power suddenly exceeded the current high-end graphics card, We must know that NVIDIA home GTX 1080 Ti graphics card TDP power consumption is only 250W, and now CPU power consumption is higher than the GPU TDP, which makes the nuclear bomb madness is good?

Joke is a joke that AMD and Intel’s nuclear war started this year is not just a matter of bringing several high-performance processors.Since AMD has had Ryzen's magic weapon, they have had a chance to change the current decline in the processor market. If Intel is willing or unwilling, it will not be possible to keep the desktop processor on four cores as in the past decade. This nuclear war may change the development of future processors, and it is called the third time in X86 history.

X86 processor shuffles for the first time: the Pentium comes out and the crowds end

Players who are familiar with the history of PC know that the PC we are talking about today is the standard established by IBM in the 1980s. The operating system isMicrosoftProvided, first DOS, followed by Windows, the processor is starting from Intel's 8088, which is the origin of the Wintel Alliance.

When Intel pushed the X86 processor more than Intel, IBM needed multiple suppliers to ensure supply. Intel licensed the X86 processor to AMD, which is the reason why AMD entered the X86 processor. What people do not know is that in addition to these two companies, there are many third-party X86 processors, including Motorola, Cyrix, National Semiconductor, and later VIA VIA. These companies can then copy Intel's X86 processors, and The name is also very similar to Intel products, such as Cyrix has launched 4x86, 5x86, 6x86 and other processors, the performance is better than Intel products, the price is lower, the pin is compatible, so it is very popular with the market.

Cyrix launched 5x86 processor

The X86 market in the late 1980s and early 1990s can be said to be flourishing. X86-compatible processors from companies such as AMD and Cyrix have suffered from Intel's higher performance and lower prices. Intel eventually ended the naming of x86 in 1993. Way, introduced the Pentium Pentium processor brand.

With the new P5 architecture, the frequency can reach 66MHz, leading the performance of other companies, opening the gap between other manufacturers.

Since then, on the X86 market, other companies have gradually withdrawn from AMD. Originally, they did not focus on X86 processors like AMD and Intel. Motorcycles, National Semiconductor and other companies are playing tickets and have other businesses. Therefore, the X86 market experienced the first shuffle after the Pentium brand came out, leaving only two regular players, AMD and Intel.

X86 processor shuffles for the second time: Core comes out and AMD is marginalized

In the years after the Pentium came out, AMD and Intel have been biting each other tightly. Although the share is still the largest among Intel, AMD was technically the winner and the winner each day. Each has its own advantages, Pentium II and Pentium III. AMD can also occasionally lead Intel processors with the K5, K6, and K6-2 architectures.

In 2000, Intel introduced the Pentium 4 processor.The P4 processor was initially welcomed by PC makers and consumers, but AMD launched Thunderbird's core Athlon processor. The performance advantage gradually emerged. P4 began to be unable to stand still. By 2003, AMD's K8 Sledgehammer processor With the advent of the 64-bit architecture, Intel lost power, and Intel forced Rambus memory to disregard mainstream DDR memory.The end of the P4 generation also saw everyone.

However, AMD's landscape didn't last long. Although Intel's P4 failed, its counterattack was also very fast. Intel quickly turned around and launched the Core architecture. The "bucket" era came, and the high-performance, low-power P6 microarchitecture helped Intel. Recovering lost ground, AMD continued to suffer from the K10 and bulldozer architecture after K8.

After Intel won the Core architecture, it did not stop and then launched the Tick-Tock strategy. It upgraded the technology every two years, upgraded the architecture every two years, and launched a new generation of processors every year.From 45nm Penryn (Core architecture first generation product) to 14nm process Broadwell.

In the past 10 years, AMD has been left and right like Intel in the P4 era, unable to cope with Intel's offense. After bulldozer architecture lost processor, AMD actually stopped new architecture processor products in 2012 and developed a new generation. Zen architecture.

X86 processor shuffles for the third time: the arrival of the era of ultra-multi-core processors

Why do we think that it is so important for AMD and Intel to compete to launch 28-core and 32-core processors this year. Maybe it is the third time in the history of X86? It is because there has been no significant improvement in desktop processors over the past 10 years. As a result, the whole DIY industry and even the PC industry have been developing slowly.

Today's semiconductor process technology is approaching the physical limit and it becomes more difficult to upgrade the process after 10nmIt is no longer possible to expect a significant increase in processor frequency. There is not much room for single-core IPC performance. In recent years, everyone said that Intel upgrades toothpaste. They also have difficulties, but it is Intel’s mistake to be indifferent to multi-core. Now.

It has been many years that mainstream processors have stayed at the level of four cores. Intel has lacked the competitive power. Second, it believes that desktop applications do not support multi-core well enough to use so many cores. This theory seems very reasonable, but it is actually a chicken or egg problems - desktop applications for multi-core support is not good enough because many desktop mainstream processors have only 2 cores, 4 cores for many years, AMD and Intel do not In advance of the multi-core processor to the desktop market, how software vendors may take the initiative to optimize applications, only the hardware first, software optimization can follow, rather than wait for software optimization clearance, Intel and then push multi-core processors.

This principle has been staged once on the X64 instruction set. Intel's 64-bit instruction set is much earlier than AMD, but why it was first taken by AMD, because Intel believes that the desktop market push 64 is useless, resulting in missed opportunities. Nowadays, Intel has such a mentality on ultra-multi-core processors. Fortunately, AMD has once again awakened. Ryzen began to popularize eight-core 16-thread processors on the desktop, and the high-end market pushed for 16-core processors. This year it is 32-core processor.

Now that Intel has started its development, the desktop market has begun to push multi-core processors. Although it is only a fever-class market, there will be 8 core 16-thread processors in the mainstream market. It will be logical to push 10 cores and 12 cores in the future. Things.

Just like the X64 bit instruction set, eight, 10 or even 28 cores and 32 cores may not have too many desktop applications and game support in the next year or two, but there are hardware platforms, systems and software, and game manufacturers. It is possible to optimize super multi-core processors before they can be truly applied and promoted. Without AMD and Intel, the era of multi-core optimization will not even come.
