With the transition to Multi-Frame Rendering, After Effects can take advantage of multi-core CPUs. Starting with After Effects 22.0, users should see immediate performance improvements for previews and exports. On high-end systems, After Effects with Multi-Frame Rendering is up to 4x faster. We strongly recommend Core i7 or Core i9 Intel processors or AMD equivalents.

Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware vulnerabilities allow programs to steal data which is currently processed on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents.
Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre
Desktop, Laptop, and Cloud computers may be affected by Meltdown. More technically, every Intel processor which implements out-of-order execution is potentially affected, which is effectively every processor since 1995 (except Intel Itanium and Intel Atom before 2013). We successfully tested Meltdown on Intel processor generations released as early as 2011. Currently, we have only verified Meltdown on Intel processors. At the moment, it is unclear whether AMD processors are also affected by Meltdown. According to ARM, some of their processors are also affected.
Almost every system is affected by Spectre: Desktops, Laptops, Cloud Servers, as well as Smartphones. More specifically, all modern processors capable of keeping many instructions in flight are potentially vulnerable. In particular, we have verified Spectre on Intel, AMD, and ARM processors.
We would like to thank Intel for awarding us with a bug bounty for the responsible disclosure process, and their professional handling of this issue through communicating a clear timeline and connecting all involved researchers. Furthermore, we would also thank ARM for their fast response upon disclosing the issue.
Chronic wasting disease (CWD), is a contagious, always-fatal brain disease that affects members of the deer family. It was discovered in Pennsylvania's free-ranging white-tailed deer in 2012 and continues to be a threat to deer and elk in the Commonwealth.
Spectre and Meltdown individually represent classes of hardware vulnerabilities, each with a number of variants dependent on specific silicon-level functionality. Differences between manufacturers (e.g., Intel vs. AMD) and architectures (e.g., x86-64 vs. Arm) make some processors vulnerable to more variants than others. While these are fundamentally hardware design flaws, attempts to remediate on a software level have seen some success.
Understanding of Spectre and Meltdown has increased significantly since the initial disclosure, and security researchers continue to study these vulnerabilities. Presently, 13 Spectre variants and 14 Meltdown variants have been identified. Initially, AMD processors were thought to be immune to Meltdown, though one variant has been successfully demonstrated on AMD systems.
Improvements in performance in modern processors are derived from a number of techniques. Limitations in augmenting the physical attributes of processors (shrinking transistor size and increasing clock frequencies) require architectural changes to how processors work in order to deliver higher-performing parts. These changes focus largely on parallelism: Optimizing and lengthening instruction pipelines, allowing multiple operations to be performed in parallel in a logical core (thread), and increasing the number of logical and physical cores on a processor.
Other properties in modern processors include virtual (paged) memory, a method that streamlines memory management across processes, privilege levels, which allow operating systems to control which areas of virtual memory can be read by other processes, and CPU cache, in which data in system RAM is cached in order to reduce latency.
Spectre and Meltdown are wide-ranging hardware flaws that affect the vast majority of devices currently available for sale, devices currently deployed, and legacy devices dating back to the 1990s, though significant exceptions exist. Because Spectre and Meltdown individually represent a class of flaws-not a single vulnerability-the differences in microarchitecture design in different types of processors impact the extent to which processors are affected.
Intel Core and succeeding generations of that microarchitecture, including Nehalem, Sandy Bridge, Haswell, and Skylake, trace their lineage from P6, and are affected, as are the low-power Silvermont and Goldmont microarchitectures. Together, these microarchitectures comprise effectively every Intel Core and Intel Xeon processor since 2006, and Intel Atom processors since 2013, the full list of which is provided by Intel.
Conversely, the Itanium microarchitecture (IA-64) is not affected by Spectre and Meltdown, which is explicitly parallel, in-order, requiring the compiler to define what can be done in parallel. Without speculative execution, Spectre and Meltdown are not usable. Likewise, the Bonnell microarchitecture lacks speculative execution capabilities in the interest of power savings, making first-generation Atom processors immune.
SoCs such as the Qualcomm Snapdragon, Apple A-Series, MediaTek Helio, and NVIDIA Tegra, as well as SoCs from other companies including Broadcom, and server processors including Cavium ThunderX, Qualcomm Centriq, and Amazon (AWS) Graviton, utilize Arm microarchitectures.
New processors do address the Spectre and Meltdown vulnerabilities at a hardware level, though buying a new processor for that reason alone is probably unwarranted. Patches presently available and immediately on the horizon reduce performance penalties for security to background noise.
The 32-core limit is designed to minimize customer impact given current core counts for most CPUs used in the industry. This change will likely have no impact on the vast majority of our current customers since they use Intel and AMD-based servers that are at or below the 32-core threshold. For the few customers who are currently deploying our software on CPUs with more than 32 cores, or for those that are in the process of purchasing physical servers with more than 32 cores per CPU, we are providing a grace period after the licensing metric change goes into effect on April 2, 2020. Any customer who purchases VMware software licenses, for deployment on a physical server with more than 32-cores per CPU, prior to April 30, 2020 will be eligible for additional free per-CPU licenses to cover the CPUs on that server.
Any customer that purchases VMware software per-CPU licenses, to be deployed on a physical server with more than 32 cores per CPU, prior to April 30, 2020 will be eligible for additional free per-CPU licenses to cover the cores on those CPUs.
A: The vast majority of the currently installed base of VMware software is deployed on existing Intel and AMD-based servers that are at or below the 32-core threshold. Any current customers that purchase VMware software licenses, to be deployed on a physical server with more than 32-cores per CPU, prior to April 30, 2020 will be eligible for additional free per-CPU licenses to cover the CPUs on that server.
A: The new licensing policy is applicable to customers with unredeemed HPP/EPP credits. Any customers that redeem HPP/EPP credits for VMware software per-CPU licenses, to be deployed on a physical server with more than 32-cores per CPU, prior to April 30, 2020 will be eligible for additional free per-CPU licenses.

T Series laptops are powerful enough to replace any desktop PC, with some of the fastest Intel and AMD processors on the market. Yet they are still highly portable -- some T Series models weigh less than 3 lbs. and offer up to 20 hours of unplugged work time. And like other advanced ThinkPad models, T Series laptops offer the discrete Trusted Platform Module (dTPM) for secure storage of encryption keys and digital certificates, as well as remote IT management capabilities (from both Intel and AMD).
The X Series includes the popular ThinkPad X1 line that's even thinner and faster-charging than other X Series models. ThinkPad X1 Carbon laptops weigh as little as 2.5 lbs. and are built for superior portability, with durable but lightweight construction, integrated graphics and multiple low-power processor options to extend unplugged time. ThinkPad X1 Extreme laptops are slightly heavier (about 4 lbs.) and boast similar thinness, but you can configure them with higher-resolution displays, faster processors, and dedicated graphics. The X Series even has 2-in-1 models: The ThinkPad X1 Yoga works as either a laptop or a tablet. 2ff7e9595c
