And if your an avid overclocker, then a Coffeelake System clocked at 5ghz will still tear up ryzen 7 even with the patches installed because a 5ghz 6core coffeelake is not a machine you can laugh at unless u own it and your laughing at how simple it was to get there. However if your going to use an older editing program which is more based on single threaded, like Adobe Premier, or Photoshop, or gaming, then your still better off on a Coffee Lake system as or even a x299 based system with quad channel DDR4, because of the higher core clock on 2 cores. If your going to use a modern 4K editing program which is truely multi threaded, then yea, possibly a ThreadRipper system maybe your best bet, as it will most likely take the least amount of performance hit. The vulnerability is known to affect Skylake and later processors from Intel and Zen-based processors from AMD. The meltdown/specture says it starts at 45 / 32nm which means it starts at i7 line, where the first cpu released was the glorious Bloomfield, i7 920. In late April 2021, a related vulnerability was discovered that breaks through the security systems designed to mitigate Spectre through use of the micro-op cache. The QX9770 is a 65nm die process original Core cpu. what do you mean useful performance?Įven with the patches applied, the current gen systems will have more performance then the cpu's that aren't affected from intel.ĭo you honestly see what kind of performance hit the NVMe's took?Įven with the performance hit they are still a lot faster then the SATA SSD's, and with the higher clock count on intel on 2 cores, it will still be faster then AMD on editing programs which arent fully multi threaded like older versions of Adobe. Intel® Core™ X-series Processor Family for Intel® X299 platforms.Intel® Core™ X-series Processor Family for Intel® X99 platforms.Intel® Core™ M processor family (45nm and 32nm).Intel® Core™ i7 processor (45nm and 32nm).Intel® Core™ i5 processor (45nm and 32nm).Intel® Core™ i3 processor (45nm and 32nm) Even if Intel wouldnt quite agree that Moores law is over, its real-world performance benefits may be substantially erased after Meltdown and Spectre are tamed.A list of vulnerable ARM processors and mitigations is listed here. ![]() It affects all out-of-order Intel processors released since 1995 with the exception of Itanium and pre-2013 Atoms. Here is the list of all the Intel processors that are currently being affected by Spectre and Meltdown. Meltdown is a CPU vulnerability that allows a user mode program to access privileged kernel-mode memory. So yeah, while the performance impact of this fix on a PC system may be relatively small for individual users, it can potentially lead to major gaming performance issues – especially for online games like Fortnite or PlayerUnknown’s Battlegrounds – caused by the gaming servers. Intel processors, as well as in AMDs Zen 2 CPUs. Weaker gaming servers may reach their peak due to this security fix, resulting in possible latency issues. Spectre and Meltdown, hardware vulnerabilities in modern processors. That’s a really big performance hit and it is something that may affect gamers worldwide. As we’ve already reported, Intel will release updates for 90% of its processors by the end of next week.Īs Epic Games showcased, the CPU utilization of one of its gaming servers sky-rocketed from 25% to almost 60%. What’s really interesting here is that Intel worked closely with many other technology companies, including AMD, ARM Holdings and several operating system vendors, to develop an industry-wide approach to mitigate this issue promptly and constructively. Since most x86 software is already patched against MDS and this vulnerability has. 6 7 8 It requires the same mitigations as the MDS vulnerability affecting certain Intel CPUs. Moreover, Epic Games has shared a graph showcasing the significant performance impact of the Intel security fix on one of its gaming servers. In August 2021 a vulnerability called 'Transient Execution of Non-canonical Accesses' affecting certain AMD CPUs was disclosed. These attacks are harder to exploit, but also much harder to mitigate. Intel has just listed all its processors that are currently being affected by the Spectre and Meltdown security flaws. Spectre is an attack against two classes of issues, affecting Intel, AMD and ARM CPUs.
