4. If they previously had a 60Hz monitor, and upgraded to 120Hz or better. This improves both motion quality and latency. When poorly designed software makes you wait multiple frames, halving (or better) the frame time makes a noticeable difference.

I find this one hard to swallow. On 60Hz software is already the bottleneck even on high end hardware. If anything, it’ll drive a perfectionist mad because crappy software that the high end hardware allowed to operate just over that threshold (say 64Hz) would suddenly be exposed. I think jitter is more important than FPS and until software has caught up (likely never) I would rather cap the frame rate at 60 FPS and e…

No, he really is right.

A lot of software, especially websites, have annoying waits for Vsync that are not needed in them.

When you update styles that triggers a reflow or repaint, then you can introduce a wait for VSync in your website thats stalls flow until it is finished.

If you add 3 frames of delay at 60fps then it's 50ms of delay, and only 25ms at 120fps. It doesn't sound like a lot, but that 25ms can be the difference between feeling totally fluid and not, and a lot of websites are even worse than that.

Software can be IO bound, Network bound, CPU bound, memory bound.

Modern software is Vsync bound!

In my opinion the jump from 1080p to 4K is as significant as the jump from hdd to ssd. That's a lot of screen real estate and especially when programming I put it to use.

I disagree. The bottleneck is usually your eyes, not the monitor. On 1080p you can use small bitmap fonts that are legible even at low resolutions. 4K mostly gives you more flexible typography aesthetics, which doesn't improve programming productivity.

2k equivalent on a 4k screen feels very good on my eyes. Reducing fatigue is productivity.

From a quick read, in case anyone is wondering, this is built on the latest-gen 10nm process which is a refinement on the previous 10nm process.

I run a pretty big VDI environment — my observation is that the the latest gen stuff on Xeon is about the same as the Haswell era gear, and slower for some use cases.

We’re actually planning on running that gear longer and moving people with more memory needs to newer gear with more memory — it’s all about the maintenance cost curve. We can get much more memory now with the same density, which offsets the CPU suckage.

Damn, they're going through generations quickly! Are they racing Firefox?

Eye resolution is ridiculously high. There's a reason companies started marketing 'retina' displays.

Small fonts will not always fall into discrete pixels which is especially true if the resolution is not very high. Which requires you to do antialiasing or mangle the characters.

Higher resolution displays allows you to render them more faithfully.

intel also has new LOGO .

The "flat" trend has infected it too, and it's unfortunate because the new logos look more like something from the fashion/cosmetics industry than a serious semiconductor company.

...still not as bad as what happened to Atmel's logo, however.

Is 10nm finally yielding or is this a paper launch / "10nm"? EDIT: ah, these are laptop chips, that's the catch.

The rumor mill suggets the volume is similar to Ice Lake (very very low)

Any links or sources?

Intel has been releasing one "generation" per year for... over 11 years? It's kind of tautological since they define a generation as whatever they release in a given year.

Is that network constrained?

> Anecdote: a family member and software dev just bought the latest macbook pro coming from about an 8 year old macbook pro. Apparently he doesn't perceive much real world performance difference between the 2 machines. He said single core synthetic benchmarks were higher, but not by much.

I just upgraded my 13" MBP from a 2017 i7 to the 2020 i7.

Single core benchmarks are basically the same but it's also running at 2/3 the clock speed, so much cooler. Plus two additional cores.
