Intel recently resigned itself to engaging in a price war with AMD’s EPYC processors as it https://vnunetblogs.com/female-dating-psychology/. Now AMD is taking the battle in an entirely different direction as it unveils three new workload-optimized processors that strike at the heart of the mid-range market, but with higher pricing than the preceding models.
AMD says the new 7Fx2 frequency-optimized processors offer the world’s fastest per-core performance from x86 server CPUs as the company looks to upset Intel’s traditional leadership position in per-core performance. The boosted performance comes as a byproduct of an increased base frequency of 500 MHz paired with a healthy dollop of extra L3 cache that benefits workloads that benefit from keeping data close to the execution cores, like relational databases, high performance computing (HPC), and hyperconverged infrastructure (HCI) applications.
The tradeoff comes in the form of a higher TDP rating, meaning the processors consume more power and generate more heat, along with the higher pricing that comes as a result of the premium-binned silicon. However, the three new EPYC Rome 7Fx2 processors offset those metrics with much higher performance, thus enabling denser solutions. AMD says that combination leads to reduced up-front costs and a 50% reduction in total operating costs (TCO) for the target markets, thus justifying the higher price points.
AMD continues to nibble away at Intel’s data center market share and says that it is on track to reach mid-double-digit share by the second quarter of this year. The new 7Fx2-series processors look to broaden that attack into applications where Intel has traditionally held the advantage. Let’s take a closer look.

The new processors come in 8-, 16-, and 24-core flavors that wield notable increases in both base and boost frequencies. They still come with the same 7nm process and Zen 2 microarchitecture found on other EPYC Rome processors, but AMD says its targeted refinements equate to a sizeable performance advantage over preceding models. AMD provided estimated SPEC2017_int_base benchmarks that show a sizeable increase in both performance-per-core and performance-per-dollar in the lightly-threaded workloads that have long been one of Intel Xeon’s strongest selling points, particularly for software that is licensed on a per-core basis. These types of applications command high premiums that increase based upon the number of active cores, so per-core performance is paramount.
As with all vendor-supplied benchmarks, not to mention estimations, take these with a grain of salt. However, we do have processors in for testing, and these benchmarks coincide with our basic expectations for the improved specifications. AMD also has the advantage of more memory channels (eight vs. Intel’s six) and faster supported memory speeds (DDR4-3200 vs. Intel’s DDR4-2933). Couple that with a higher 4TB memory capacity (Intel tops out at 2TB without additional fees) and 128 lanes of PCIe 4.0 (Intel has 48 lanes of PCIe 3.0), and AMD has a compelling performance story.

As we can see, the top of the stack remains unchanged. But while those models tend to grab the flashbulbs, the real volume resides in the mid-range dual-socket server market.
AMD’s new models slot in below the new VMware licensing model that black girl white guys dating sex. The increased per-core performance also benefits systems where per-core licensing costs often outweigh the price of the hardware. Utilizing the software more fully will ultimately reduce cost, and AMD tackles that mission with a 500 MHz increase to the base frequencies. That comes with a 60W increase in TDP for the 24-core 48-thread EPYC 7F72, a 90W increase for the 16-core 32-thread EPYC 7F52, and a 25W increase for the EPYC 7F32.
AMD also increased the boost frequency to 3.7 GHz for its 24-core model, and 3.9 GHz for its 16- and 8-core variants. These boost frequencies adhere to AMD’s standard practice of guaranteeing the rating for one physical core only, which is then complemented by thread-targeting that ensures the fastest core receives the brunt of single-threaded workloads.
The increased L3 cache capacities also pop off the page, with the 24-core model sporting 192MB of L3, a 64MB increase, and the 16-core model weighs in with a whopping 256MB of cache, an incredible increase of 128MB. This beefy cache is incredibly potent in the target applications and contributes to the increased per-core performance.
The chips come with a higher price point to match the specifications. The 24-core model weighs in at $2,450, an extra $667 over AMD’s comparable model but still less expensive than Intel’s $2,700 Gold 6248R. The 16-core model retails for $3,100, a $2,122 markup over the 7302. This model lands only slightly below Intel’s $3,286 Gold 6246R, underlining AMD’s confidence that it has the faster chip. That comes despite the 6246R’s higher boost frequency, but that’s the advantage of AMD’s 256MB of L3 cache compared to Intel’s 35.75MB.

AMD cited performance benchmarks in a few applications that typically come with per-core licensing models. That includes a surprising claim of 31% more performance from a single 7F72 model than two of Intel’s Xeon Gold 6246 chips.
Improved performance is great, but it won’t enjoy broad uptake if there isn’t a robust set of qualified solutions available from reputable vendors. As such, AMD has been busy building out its ecosystem of platforms. The company now has 110 platforms in the market and plans to expand to 140+ by the end of 2020 from the likes of Dell, HPE, and Lenovo, among others.
AMD also continues to broaden the spate of instances available through cloud service providers, with 106 available now in all flavors, from compute to balanced types, and plans for 150+ by the end of the year. These instances come from industry leaders like AWS, Microsoft, Google, IBM, Oracle, Tencent, and Baidu.
AMD also announced today that it has been certified on Nutanix platforms from HPE, and Supermicro has launched its first blade-based EPYC Rome system with its SuperBlade system.

AMD’s move marks a starkly different tack than Intel has taken lately as the latter has reduced pricing across the board to assuage customers that now have a less expensive x86 alternative. Despite Intel’s price adjustments, AMD still holds the value crown and its expansion into the frequency-optimized category gives it yet another angle of attack on the lucrative server market.
We’re working on a full review of the new models as we pit them against Intel’s Cascade Lake Refresh models. Stay tuned.
