[Edit/Modify Cache Info]
Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |

64-core Epyc 7742 CPU priced at less than $8000
2nd generation AMD Epyc processors due in Q3. Recall that these server CPUs have switched to a seven-nanometer process technology and Zen 2 architecture. In addition, the number of cores has doubled, so that the flagships are now 64-core.
And now both the parameters of these processors and retail prices have appeared on the Web. To clarify, prices are retail prices with 21 percent VAT.

Epyc 7252 | 8/16 | 3.2 | 64 | 120 | 577 |
As you can see, prices have increased significantly. The flagship of the previous generation, the Epyc 7601 model, once started at $4,200, but the number of cores has doubled. And if we compare exactly by this parameter, then it turns out that prices have dropped a lot: a 32-core Epyc 7502 costs only 3100 euros!
You can often not even compare with Intel. For example, we recently saw a 32-core Epyc 7452 take on a 20-core Xeon Gold 6148, which seemed strange because the number of cores is so different. But now everything has become clear: the first costs about $2,700, and the second costs $3,000.

Overview of the new AMD EPYC 7F52 processor: F stands for frequency
Everyone wants a fast processor. Being able to do more things is one of the guiding principles of business. However, businesses also need consistency, security, and protection, so enterprise-class processors are often a requirement in a server infrastructure. These processors with a lot of cores are not as fast as consumer processors, so it becomes an issue whether it makes sense to run fast without protection or take risks on a proven platform. The goal of the new AMD 7F processors is to provide this proven platform with ultra-fast cores with large caches. We have 7F52 for testing today.
The enterprise market wants it all
The nature of the latest generation of enterprise processors tends to increase the number of cores and increase the amount of cache memory. As power budgets increased, it was decided to add more cores to ensure stability and get the best efficiency scores. However, there are still markets that require high-frequency components, and it’s quite common for users to turn their attention to consumer equipment that doesn’t offer enterprise world features such as ECC memory, RAS features, management, and high-speed I/O. We’ve seen OEMs build servers on very rare consumer-grade processors, such as auctioned 5-core, 14GHz parts that provide the best performance but don’t use basic enterprise features like ECC memory.
To this end, AMD Enterprise is developing several high frequency processors in its EPYC hardware line to serve this market. We saw that with the first generation EPYC «Naples» processors, AMD released a custom EPYC 7371 processor that offered 16 cores but had a base frequency of +700 MHz and a turbo frequency of +900 MHz compared to the next best 16-core processors. part, and the compromise was only +30W of power and paying a little more. At the time, the EPYC 7371, which was launched a few months after the rest of the product line was released, was the test case for the new 7F high frequency processor line.
AMD 7F and 7H: Aiming for High Performance
The best way to look at AMD’s EPYC processor line, especially for second generation Rome hardware, is comprised of four segments.
Main stack first. These are common processors for most of the market, from the 7252 with eight cores to the 7742 with 64 cores. All are dual socket compatible and range in power from 155W to 225W (except for the 120W models 7252 and 7262).

Second, single socket processors. These are variants of the main stack, but marked with a P at the end, as they are designed for systems that require only one processor. The benefit is that P processors are actually cheaper ($2600 for a 32-core 7502 compared to $2300 for a 7502P) if the customer can guarantee they will never need a dual socket design. They also go from 8 cores to 64 cores.

Three — this is a family of processors 7H, which currently has only one member. It launched a couple of months after the first two segments, and the «H» stands for High Performance Computing. The power limits of this chip have been increased to 280W, and the goal is to maintain a higher constant frequency than conventional parts. For example, the 7742 has a base frequency of 2.25 GHz at 225W, but the 7h22 has a base frequency of 2.60 GHz at 280W. The 7H processors are not in retail sale as far as we can tell, but specific customers may request them. their.

Fourth, this is the latest set of equipment, the 7F family. The F in this case refers to frequency and these parts are the spiritual successors of the 7371 in the latest generation: a much higher base frequency and a much higher RPM for the consumer. AMD also equips these processors with more cache, so the cache per core can effectively quadruple.
ROME 7F family includes three members:

These processors look a bit confusing.
For 8-core 7F32 and 16-core 7F52, AMD uses 1 core per CCX or 2 cores per chipset, which is equivalent to 16 MB of L3 cache per core. This is four times more than any other AMD EPYC processor.
The 24-core 7F72 is cheaper than the 16-core one because AMD is adjusting the cache level offered here to 192MB. This means that this processor only has six of the eight active chiplets, and each CCX will have two active cores (6 chiplets * 2 CCX per chipset * 2 cores per CCX = 24). The frequency is slightly lower due to the increased density of the active core, so along with the cache reduction, AMD felt the need to price it lower than the 7F52.
For this review, we are testing 7F52 processors. Compared to the base 7302 16-core CPU offered by AMD, this means another +500 MHz at base frequency and +600 MHz at turbo frequency, but will also increase from 155W to 225W.
Naturally, some of the key comparison points for the 7F52 processor will be equivalent to 16-core Intel processors like the new Xeon Gold 6226R, or compared to 28/32 base variants from both Intel and AMD.
