38% int IPC gain, 68% float IPC gain. This could be the "Conroe Moment" 2.0.
3x3 clustered decoder, 8 ALU units, and 4x128 vector units. This really is a quiet exciting architecture.

because area density is not the point, power efficiency is. That where zen4c gone wrong.

The clustered instruction decoders is more scalable and power efficient than the coventional approach.
The "mont" cores is just so much more interesting with much higher potentials.

Yes, those are the main points. Sun Tsu realized that war is a terrible thing, especially the human suffering. He wrote "Art of War" to admonish rulers to understand and avoid war.

今天is Chinese word not Japanese. 今日and今天have the same meaning in Chinese.

May be you should try attaching depth/normal maps to tile. Let shader use zbuffer to sort for you. Similar to https://assetstore.unity.com/packages/templates/systems/2-5d...
Most 2d engines use shader system underneath, it easier to write a shader to solved all the z-sorting problems. Only minimal 3d maths and billboarding(tile) are all you need.

"擬諭英吉利國王檄", https://kknews.cc/zh-tw/history/ybvzq2k.html has original and pretty good "白話文" translation.

No, 夷人(foreigner)，was used.
websg-x | 4 years ago | on: Understanding the global chip shortages
Huawei start buying huge amount of chips when there was rumor that US going to imposed sanctions on Huawei, and when the sanction hits, every major chips users in China start buying too, they were afraid that they will be next on sanction lists. They kept buying chips to build up safe inventory level during the early pandemic period when western firms were cutting orders.
Of course, when demands returned, Chinese companies were still on buying spree. The shrewd middleman everywhere, not just in China, saw shortage coming, and they stock piling chips too.
Yeah, most semi-industry people in Taiwan think that US sanctions and the threat to impose more sanctions definitely contribute to the current shortage.

Alder Lake-s is already in distributors warehouse. It will go on sale Nov 4th.
websg-x | 4 years ago | on: Intel’s Gracemont Small Core Eclipses Last-Gen Big Core Performance
From reading anandtech, I think Intel compared gracemont against 6700k。
Yeah, it just such a great idea with great execution, but most people just don't realize it yet. It like the chiplet situation with Zen.
websg-x | 4 years ago | on: Intel’s Gracemont Small Core Eclipses Last-Gen Big Core Performance
it small in size，around 1/4 the size of big "Golden Cove" core. Gracemont is a big architecture enhancement over Tremont Core, which is nurtured by the legendary Jim Keller.
No avx512, but not skimpy in floating point.
The rumor is that Intel "Sierra Forest" will contain huge amount of small cores.

14->10 was a disaster so we should ignore that, and that the reason Pat Gelsinger is brought back to fixed.
TSMC pioneered the half node step, and it was very successful. So yes, I think copying successful strategy is a conservative approach.
websg-x | 4 years ago | on: Intel to build Qualcomm chips, aims to catch foundry rivals by 2025
7 is half node, 4 full node, 3 half, 20A full node again. Moore's law is doubling of transistors density every 2 years. So the roadmap is indeed conservative, just following the Moore's law.

TSMC deny the report and is proceeding with the original plan at this stage.

https://www.trendforce.com.tw/research/download/RP210112CQ
The report is all speculation, not some credible source leak.
And the original report was released on 01/12 before Intel appoints Pat Gelsinger as new CEO. So even if the report speculated correctly, which is unlikely, the circumstance already changed.

Intel already got 'Foveros 3D Chip Stacking’ Tech shipping last June, the Lakefield processor.

3080 use GDDR6x. Yes, the 20gb 3080 is cancelled, but there is a new rumor about 12gb 3080ti. So maybe GDDR6x scarcity is the culprit, not Samsung's process.

I guess there was 180k wafers allocated to Huawei before US sanction, but that has nothing to do with Intel.
