Ethereum: What mining performance can we expect from Intel Sha extensions of the future Skylake processor architecture

As the next generation of high -performance calculation processors, the future Skylake promises a Micarchitecture in order to achieve significant improvements in various aspects of performance and efficiency. One of the most important areas that are strongly influenced by the new processor architecture is the mining performance of Ethereum.

The secure expansion of the Hash -Algorithm (SHA), which was announced by Intel as part of the Skylake X86 Mikroarchitecture, aims to provide a significant impulse for the accelerated processing skills, including blockchain and cryptocurrency cuts. In this article we will take a closer look at which mining performance can be expected from the architecture of Skylake processors that concentrate on Ethereum.

Background: How does Sha work

Before you immerse yourself in the details of the Skylake processor architecture, it is important to understand how Sha works. Safe hash algorithms are used for data integrity and cryptographic purposes in various applications, including blockchain and cryptocurrency systems. The SHA-256 algorithm is an example on a large scale in which a hash function is used to create a fixed area from a string.

You expand the Skylake architecture

The Skylake Mikroarchitecture of Intel X86 provides several important innovations for SH processing:

• Hardware acceleration : The Skylake processor architecture offers hardware acceleration for SHA algorithms, so that they can be carried out faster and more efficiently with special hardware accelerators.

• improved parallelism on instructions (ILP) : The new architecture has improved ILP functions, so that the efficient use of several processing cores can accelerate various tasks, including SHA calculations.

Expectations of mining performance

Although we do not have a precise date for the architecture of the Skylake processor or its extensions, we can make some well -founded estimates based on the trends of the industry and the previous advances. Here are some factors that influence mining performance in Ethereum:

• hash rate

  

  : The Hash rate of a GPU (graphic processing unit) is directly proportional to the clock speed, memory size, number of kernels and the support of the shader model.

• clock speed : Since the Skylake processor architecture introduces higher clock speeds for its basic processing units, it increases the general performance of GPU in terms of SHA calculations.

Mining roughly expected

Suppose we talk about well-established Ethereum mining equipment with a decent GPU (e.g. Nvidia GeForce GTX 1080 or AMD Radeon RX 580) and an Intel (Intel Core i7-6700K) processor, here is a hard performance -Mining estimate that the estimate of the performance mines for the reduction in performance, which is estimated, which is estimated can be expected from the architecture of the Skylake processor:

* clock speed

: Depending on the specific model, the new Intel processor will probably have a speed of around 3.6 GHz to 4.2 GHz.

* hash rate : With an estimated speed of the GPU clock between 1.5 and 2.0 GHz (depending on the GPU) and a total clock of about 3.9 GHz to 4, 2 GHz, we can at least 20 % expect up to 30%.

* Mining performance : This leads to an estimated impulse of 10% to 15% in the mining performance compared to older architecture (e.g. Sandy Bridge or Haswell).

Diploma

The introduction of SHA extensions into the Intel Skylake microarchitecture promises significant improvements in the accelerated hardware processing capacities for Ethereum Mountain. Although we have no precise estimates, a rough estimate suggests that mining performance increases by 10% to 15%, which can be preserved with a well-established GPU and an Intel Core i7-6700K processor.
