AMD Released The Fastest Single-Core Processor In The World

What this time brings is the EPYC Rome 7Fx2 series with the "world's fastest single-core performance" on x86 server CPUs. The new three processors are complementary to the second-generation processor product line and belong to the top products among 8-core, 16-core and 24-core processors. Compared with the products released in 2019, the clock frequency has been greatly improved, and the level 3 cache capacity is larger. In terms of price, it still refers to Intel: compared with Intel Xeon processors of the same level, it can reduce costs by up to 50%. Without further explanation, let's look at the parameters.

The world's fastest single-core CPU
AMD EPYC processor for data centers. As soon as the AMD EPYC 7002 series in August 2019 came out, it grabbed the eye with a luxurious configuration: 7nm processor, up to 64 cores and 128 threads, 256 MB L3 cache, support for 8-channel DDR4-3200 MHz memory, and 128 PCIe 4.0 channels.

The newly introduced 7F32, 7F52 and 7F72 three processors have the tendency to impact Intel's traditional leadership in single-core performance. Compared with the 8-24 core second-generation Xiaolong CPU introduced last year, the clock frequency has increased by at least 500 MHz, and the level 3 cache capacity continues to expand. For workloads that are closely related to the execution core (such as relational databases, high-performance computing, and hyper-converged infrastructure applications), the benefits are enticing.

In particular, the 7F32, 8 cores and 16 threads, basic frequency is 3700 MHz, enhancement frequency is around 3900 MHz, the L3 cache is 128 MB, TDP is 180 W. The price is 2100 US dollars. Compared with the previous EPYC 7262 and 7252, the basic frequency is 500 MHz higher. The 7F32 benchmarks are Intel Xeon Gold 6250 and Xeon Gold 6244, which are priced at 3,400 US dollars and 2,925 US dollars respectively.

7F52 have 16 cores and 32 threads, basic frequency is 3700 MHz, enhancement frequency is around 3900 MHz, L3 cache is 256 MB, TDP is 240 W. The price is 3100 US dollars. Similarly, the basic frequency is higher than the 3000 MHz and 2800 MHz of the same series of EPTC 7302 and 7282. The 7F52 benchmarks are Intel Xeon Gold 6242 and Xeon Gold 6246R, which are priced at US$ 2529 and US $ 3286 respectively.

The 7F72 have 24 cores and 48 threads, basic frequency is 3200 MHz, enhancement frequency is around 3700 MHz, L3 cache is 192 MB, and TDP is 240 W. The price is 2450 US dollars. The basic frequencies of the same series of EPYC 7402 and 7352 are 2800 MHz and 2300 MHz, respectively. The 7F72 benchmarks are Intel Xeon Gold 6248R and Xeon Platinum 8268, which are priced at US $ 2700 and US $ 6302.

To summarize, the EPYC 7Fx2 series processors use the 7nm process Zen 2 architecture, support 8-channel DDR4-3200 MHz memory, 4 TB storage capacity and 128 PCIe 4.0 channels; Intel's same-level products support 6-channel DDR4-2933, the highest 2 TB storage capacity and 48 PCIe 3.0 channels. So, don't look at the 16-core alignment, 7F52 does not seem to have a price advantage. It needs to be considered that the level 3 cache of Intel Xeon Gold 6242 is only 22 MB, and the 2646R is only 35.75 MB. In addition, according to AMD data, its 16-core EPYC 7F52 is also better than Intel Xeon Gold 6242 and Xeon Gold 6246R in integer and floating-point performance.

The Dell PowerEdge R6525 is equipped with EPYC 7F72, a dual-socket four-node system, and it has also set a new world record in VMmark 3.1 performance, which is an increase of 47% over the past . According to AMD, after the second quarter of 2020, manufacturers such as HPE, Lenovo, IBM Cloud, Roadtan, Supermicro, and Dell will launch products using AMD EPYC 7Fx2 series processors.
