2008年8月1日 · SSE4.1 and seven other new SSE4 instructions are supported in 45 nm Intel processors based on a new microarchitecture (code named Nehalem). The subset of the 7 new SSE4 instructions available to Intel processors based on the Nehalem microarchitecture is referred to as SSE4.2 in this document." Cheers,-Thai

2018年8月4日 · I'm looking for a list of games which require SSE4.2 instructions. As you know Q9650 and E5450 (Yorkfield & Harpertown) are good CPUs for gaming. They are cheap, can be easily modified and many use them on their old systems. But these old CPUs doesn't have SSE4.2 so games won't start, they have SSE4.1.

2019年10月19日 · MouSSE is a partial SSE4.2 emulator that allows those old CPUs to use the newer AMD drivers. While its primary focus has always been making the AMD drivers work, it also appears to allow World of Warcraft to run on a Mac Pro 3,1 regardless of whether or not AMD drivers are in use.

2021年3月1日 · SSE4.2 has been on most CPUs since Intel 1st gen and AMD FX (Bulldozer) Intel Core i9-10900X, Asus TUF X299 Mark 1, 128GB DDR4 3200MHz, Asus GTX 1080 Strix, 2TB 970 EVO Plus, 2TB SN570, 8TB HDD, DC Assassin III, Meshify 2

2018年7月16日 · It's hard finding info about what games actually require SSE4.2. The minimum requirements from the developers is not based on this. (Both AC:O and GR:W has Core i5-2500S listed as minimum cpu requirement, tho GR:W will run, surpisingly well, on a QX9650 (or X5460) @4GHz / 8GB / 1060 6GB) and when I google for it, almost everything is about old ...

2009年5月1日 · There is no current mechanism to take advantage of SSE4.2 instructions without recompilation, although there appear to be several research projects on binary translation. Existing code which uses parallel move instructions, for example, automatically takes advantage of the improved support of varying alignments in SSE4.2 (and recent AMD) CPUs.

2019年10月19日 · Part of the problem is that Photoshop looks for SSE4.2 support from the CPU, and Syncretic’s code is not built to intercept that query. So Photoshop just fails. But even if Syncretic’s patch did tell Photoshop that SSE4.2 is supported, it may not cover all the SSE4.2 features that Photoshop might call on. Hope I’ve got this right!

2013年2月28日 · Then I compiled the code using two options: 1) /QxSSE4.2 and /QaxAVX; 2) /QxSSE4.2 and ran both on E5-2690. I was expecting for the single precision an 8x peak performance improvement with AVX and a 4x improvement with SSE4.2 by vectorization. But the results I got didn't match my expection.

2021年6月11日 · You can look at the sysctl stuff by using sysctl hw.optional in Terminal.app. Note that this SSE4.2 emulator does not set any flags including "hw.optional.sse4_2" Since the problem is not caused by an illegal instruction, the MouSSE method is not the way to fix this. Maybe Lilu.kext and a patch to the GenericMacIntel.dylib would work.

2010年1月23日 · Yes, both SSE4.1 and 4.2 include SSSE3 instructions. However, compilers for SSE4.2 should avoid use of certain SSSE3 instructions, such as PALIGNR, in contexts where they were effective on the first CPUs which supported SSSE3. I guess some of the architectural changes needed to support SSE4 inherently reduced the dependence on PALIGNR for ...
