I’d be curious to the performance of the 8 Elite if it were scaled up to the M4 size.

By adding more cores you mean?

Because you can't just 'scale up' the size of an individual core. That would require designing a new core microarchitecture.

Realme confirms Qualcomm made last-minute name change to Snapdragon 8 Elite

The Snapdragon 8 Elite was supposed to be called the Snapdragon 8 Gen 4, but Qualcomm changed its flagship smartphone SoC's naming scheme again. However, as Realme confirms, it was a last-minute change of plan.
www.notebookcheck.net www.notebookcheck.net
Android Authority then reached out to Realme, and a company representative said that Qualcomm didn't notify them about the name change before GT 7 Pro's box was designed. The representative adds that the confirmation about the Snapdragon 8 Elite naming was only confirmed "several days before the Snapdragon Summit."

In this context yea, scaling up by adding more resources.

Edit: did Amon actually say they have the most area efficient core? Can’t find that.

You gotta book your tickets for the Snapdragon Summit next year, because 3rd generation Oryon is going to be awesome.

As long as ARM doesn’t win an injunction to prevent that. Plus who knows what’s up with the whole v9 ALA.

Kurnal has published his labelled dieshot of the X Elite!

With almost all major subsystems labelled.

Geekerwan has finally published their Review/Analysis of X Elite...on Bilibili.

高通X Elite深度分析：年度最自信CPU_哔哩哔哩_bilibili

普通且自信——这是我用了四个月X Elite笔记本后，对高通这款“划时代”处理器的真实评价。他有一些潜在的闪光点，包括架构设计、省电上的各种创新。但当你在生态和可用性上遥遥落后，性能上又无法隔着转译层碾压各路对手，还在市场定位和价格上痴人说梦时，这款产品就离失败不远了。X Elite到底是什么？为何我会如此评价？看完这期视频你会得到答案……, 视频播放量 1539683、弹幕量 7254、点赞数 59981、投硬币枚数 23120、收藏人数 8840、转发人数 3239, 视频作者 极客湾Geekerwan, 作者简介...

• 8 Elite can match the performance of X Elite at roughly 1/3 the power in Steel Nomad Light.

• 8 Elite scores higher than X Elite in this benchmark while running at a lower clock speed (1.5 vs 1.1 GHz), which shows the improvement of Adreno 8 sliced architecture.

It was added to Rosetta 2 earlier this year, guess Microsoft wanted to keep up! Not sure it really matters except for software that doesn't have an SSE codepath.

It’s for games that require these instructions.

SSE is slower than AVX. Also not all apps have an SSE codepath (they have AVX/AVX2).

Right now, those apps don't work on WoA, which is a big problem.

Prism gaining the ability to emulate these extensions is great.

It's been several days since, and it looks like it won't be uploaded to Youtube.

If there is anyone here who has Bilibili, can you post the important screenshots? (Unregistered users can only view the video at a max of 360p).

SSE being slower on x86 is irrelevant, since everything is translated to and executed with NEON's 128 bit registers. If you're emulating AVX which has 256 bit wide registers the translator has to break it up to fit the 128 bit registers any ARM systems able to run Windows currently have.

Games that require AVX/AVX2 makes sense as a reason to include that in the emulator. Well for Microsoft's emulator at least. Not sure if that was the reason Rosetta 2 had AVX/AVX2 added.
