computing power: in short, it is a quantitative indicator of the computing speed of your mining machine. For example, 1t computing power is the 12th power of 10 in 1s. If the 12th power of this 10 can work out the results that meet the conditions, it will be g. If not, it can be said that it is in vain
in the face of the exponential increase of data, computing power is the biggest demand for enterprises and institutions, and improving computing power requires higher performance CPU and GPU
last time, AMD processor pushed the computing power of HPC to billion times, but now AMD with epyc processor pushes the computing power of supercomputing to 10 billion times again. AMD's two E-class supercomputer systems, frontier and El Capitan, are scheled to be delivered in 2021 and 2023, respectively. They will achieve the expected processing performance of more than 150 exaflops (10 billion times) and 2 exaflops, respectively, and are expected to become the fastest supercomputer in the world
it is a big challenge for any manufacturer to improve the computing power in a short time. How did amd make such great progress? Let's start in 2017
in 2017, amd adopted a new Zen architecture, launched the first generation epyc processor, and dramatically increased the number of single processor cores to 32 cores. Two years later, the introction of the second generation epyc processor not only upgraded the architecture to zen2, but also reced the process technology from 14nm to 7Nm, which improved the IPC performance by 15%
compared with the Zen architecture, the new zen2 architecture optimizes the L1 instruction cache, doubles the operation cache capacity and floating point unit data bit width, and doubles the L3 cache to 16MB. The 64 core epyc processor easily has 128MB L3 cache. What's more, the second generation epyc adopts 7Nm process, which effectively reces the power consumption. Under 225W TDP, the number of cores can be increased to 64 cores, which makes its performance significantly improved
in the past year, the second generation of AMD epyc processor has achieved more than 140 world records, covering cloud computing, virtualization, high-performance computing, big data analysis and other fields, and also with strong performance to meet the increasing demand of enterprises or institutions for computing power
therefore, relying on the leading performance of epyc processor and ultra-high power consumption ratio, amd has not only won more market share and broken many world records, but also expanded its ecosystem.
ACCA is a vicious examination subject, but it doesn't have high requirements for mathematical calculation. It mainly tests some logical thinking, and basic calculation will be available. However, the examiner of ACCA will tell us the formula for all the questions involving complex formula. Therefore, as long as we can master the basic knowledge, we can know some basic mathematical calculation
ACCA students often have divergent opinions on data analysis in most strategy documents. ACCA examiners hope that students can not only calculate the key numbers and movements in the data provided, but also use the information in the situation and any appropriate inference in the text to interpret the data. Students tend to be strong in one field, but not in another
< H2 > start from the foundation:the key to success in ACCA is to start from the foundation. Save fancy stuff when you've accumulated markers and you're close to the end of available time
starting with sales change and gross profit margin, it is very important to evaluate business performance. Calculating this shouldn't be a problem, but after calculating them, you can look for the key drivers / reasons for the change
sales can be regarded as a mixture of quantity and price. Most scenarios will provide data about the number of houses sold, for example, houses sold; Passengers fly. Some comparative price data may be percentage commission; Percentage of first year wages; The average price of air tickets in a year
even if you only raise price / quantity issues that affect sales, you can see a significant improvement in the quality of analysis. Although a better answer would be to find the action (if possible) and gain insight into the sales review, identify the key drivers of volume change and speculate whether it's not just price
identify any new data sources for the year, which is a new source of revenue and may help to develop an open line of "sales growth x%"
for example, if a company starts to provide maintenance contracts for procts sold this year, the revenue and profit this year may be better, which will distort your data. This should encourage you to make further calculations to eliminate new revenue streams and ensure that we make similar comparisons. Please note that the specific data of last year may not be this year. For example, if the key contract was lost at the end of last year, a similar approach is needed
there may also be an opportunity to determine the difference between the procts sold and the maintenance contract, which is undoubtedly a different profit margin, further improving the number of calculations in the answer. If cost information is not available, you can briefly suggest that this additional information is useful for further analysis of business performance before continuing
look for other non-financial information, maybe provide the number of employees, so calculate the sales (or profit) of each employee to find out whether the business has effectively realized these additional sales. In terms of cost, the total number of hours used can be given, which can be used with sales to calculate the hours per unit
if you mention variable cost, why not discuss fixed cost? Here, we calculate the change and try to use the scheme to explain the possible reasons for the change of fixed cost
consider the sales mix between two or three major procts / services to be sold. Food and beverage sales, manicure and pedicure, snooker hour to pool time. Calculating the weight of income or quantity helps to determine the trend of change and the root cause of performance
if the data allows, this can be linked to the profitability of each proct - if the share of high margin procts in the overall sales portfolio declines, it will cause concern
admit any small, seemingly insignificant / insignificant number. Auditing students can be difficult to do on their own. It will still affect the performance of the organization. Sales of swimming equipment in local leisure centers; Duty free sales on aircraft; Gift shop sales of sports events
the share of labor remuneration in GDP is an indicator to measure the degree of labor sharing in the primary distribution, and it is also one of the core issues of income distribution.
The general formula of proction function is y = AF (k, n), and the specific formula is Cobb Douglas proction function y = AK^ θ N^(1- θ)
