2012年8月28日 · Hi according to the many articles I have read, the C2D E7500 supports SSE4.1, however I have just downloaded the latest Intel CPU ID utility and it states that SSE4 is not a feature of this CPU. The version of Intel CPU ID is 4.50.20120413. However the older version of intel CPU ID 4.32.20110608 says that the CPU does have the SSE4 feature.

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.

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.

2010年8月6日 · Note that most AMD and Intel processors produced today support the SSE2 and SSE3 instruction sets. The SSE4a instruction set is unique to AMD processors and is not supported by the Intel IPP library. As you can see from the chart in the table above, after SSE3, the library supports the SSSE3, SSE4.1, SSE4.2, AES-NI and AVX instruction sets.

2009年5月20日 · Presentations about SSE4.2 architecture point out that it would be preferable to make only a single version. The gnu compiler choices to avoid performance problems with unaligned vectorized loads are splitting into 64-bit loads (the default, not good for recent CPUs), or the use of movaps and the like in spite of misalignment (-march=barcelona ...

2010年1月26日 · Hi, I see on Wikipedia that SSE4.1 has the instructions PMULDQ and PMULLD for packed signed multiplication. So are there any instructions (preferably intrinsic functions) for packed unsigned multiplication? Also, if I were only to use the compiler switch -msse4 without any explicit intrinsic functio...

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!

2025年2月14日 · There are free utilities that will show a list of the instructions that a CPU supports such as SSE4. An example is CPU-Z that can be downloaded from this page . Below is a section from a screenshot of the info that CPU-Z can display. Provided that both SSE4.1 and SEE4.2 are shown as supported by your CPU then it should work OK with Capture One.

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.

2019年10月19日 · SSE4.2 consists of 6 or 7 instructions. SSE4.2 "proper" consists of CRC32, PCMPGTQ, PCMPESTRI, PCMPESTRM, PCMPISTRI, and PCMPISTRM. Another instruction, POPCNT, was introduced at the same time as SSE4.2, and is often lumped together with them, even though they're not actually related. MouSSE implements CRC32, PCMPGTQ, and …
