AMD EPYC Rome 7x32 Server Processors - Record Single Core Performance

Fewer cores, higher frequency. In some tasks it’s more profitable.

2nd generation EPYC Rome: 8.34 billion transistors on a central IOD chip with an area of ​​416 mm ² (12 nm) plus eight CCD crystals with an area of ​​74 mm ² (7 nm), totaling 39.54 billion transistors on the entire chip ( increase )

The war between Intel and AMD has long been going on desktops and laptops, and now flares up in the server market. Judging by the dynamics, AMD seems to be more aggressive, because it represents new models, and Intel responds with lower prices. AMD delivered another blow yesterday with the presentation of three second-generation EPYC Rome processors : these are the 7F32, 7F52 and 7F72 on 8, 16 and 24 cores. Here, the company applied a new tactic, reducing the number of cores, but increasing the performance of each core.

The new models are unusually small cores, but AMD overclocked them to the maximum base frequency. The difference between the base frequency and the turbo is minimal. For example, the eight-core EPYC 7F32 operates at a base frequency of 3.7 GHz and accelerates to only 3.9 GHz.

You have to pay higher TDP for this, so processors consume more power and generate more heat (that is, they will also require more energy to cool). However, AMD claims that the three new EPYC Rome 7Fx2 processors compensate for this with much higher performance, which allows for “more solid solutions.” AMD says that this combination leads to a reduction in initial costs and a 50% reduction in total operating costs (TCO) for target markets.

The increased capacity of the L3 cache is striking, with the 24-core model having 192 MB of L3 cache, while the 16-core model has a whopping 256 MB of cache. This powerful cache is incredibly effective in the specific applications that these processors are designed for, and helps improve the performance of each core.

The performance of some systems can be compared in the test results of the Phoronix laboratory .

AMD says the new server processors are tailored to the specific needs of infrastructure providers, high-performance computing and relational databases, which need high-performance individual cores. These tasks are either not very well parallelized across the cores, or they should provide particularly low latencies, or require fast I / O connections for various storage systems or network components. For example, it is beneficial to use such processors in the VMware licensing model, which charges for the number of cores.



The increased performance of each core is particularly beneficial for systems where the licensing costs of each core outweigh the price of hardware. A more complete use of the software will ultimately lead to lower costs, and AMD solves this problem with an increase in base frequencies, sacrificing TDP.

In terms of performance on a single core, the new AMD chips are superior to competitors, and the youngest eight-core set an absolute record for the 2P SPECrate 2017_int_base test, according to AMD, the numbers on the graphs. Performance comparison on the core of server processors AMD and Intel




AMD Starts New Partnerships - Suppliers Launch Products With EPYC Processors. Among them is Supermicro, which launched the first blade server with EPYC processors and an IBM Cloud cloud instance with direct access to 48 physical cores. There are currently 110 products with EPYC processors in the market, and the company plans to expand to 140+ by the end of 2020 with the help of companies such as Dell, HPE and Lenovo. Tyan Transport HX TS75A-B8252 At the same time, there were rumors that "some company" took up the old and again began to bribe vendors so that they would not use AMD processors or delay the release of products based on them. Recall, for this Intel was fined 1.09 billion euros




in 2009. Then the European Commission demanded an end to such a practice.
