Weird to see this "partial" announcement - since it's mostly for the U-series chips (up to 28W TDP). This suggests that Intel must really be getting pressure to release something competitive against AMD's Renoir offerings. The more performance-orient chips (traditionally known as "H series" but who know the new branding...) is still unannounced and unknown. Will have for 3rd party benchmarks to determine the real per…

Yeah. But I think 4 cores at 50% higher base single thread vs 8 cores is actually a pretty reasonable tradeoff for many workloads. If they managed 6 cores though... would have been pretty awesome. I hope this delivers. I'd hate to see Intel go down in flames.

Right, that's perhaps a glaring omission. Last year's (Ice Lake) i7-10710U was a 6-core, 12-thread part with a TDP of 25W. https://ark.intel.com/content/www/us/en/ark/products/196448/...

But it's entirely missing from this announcement. Seems like a regression.

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. Intel's goal was to focus on clock increases, so the instruction per clock is apparently not much changed. From looking at the tables, the whole line of processors appear to have nicely improved one core max clock speeds, which should hopefully help single core performance,…

On the topic of noticing performance improvements, I'd definitely say that we've plateaued as far as "general snappyness" in all aspects but one: high-refresh rate, low latency displays.

I recently upgraded my monitor from a Dell U3014 to an OMEN 27i (it's gaudy and "gamer" oriented, but it was the best I could get in an afternoon at a physical store). That's an upgrade from a 60 Hz monitor to a 165 Hz monitor, and a significant (though not numerically measured so far) drop in input delay, some tens-of-milliseconds.

This has been the biggest improvement in "snappyness" that I've experienced since I moved to solid-state storage 10 years ago.

The contrast in community enthusiasm between this and Nvidia's 3xxx announcement could not be more severe.

This claims they are announcing and not actually launching. No dates or prices:

Please leave these in r/gaming

Incidentally, the nVidia presentation yesterday made a Crysis joke.

Also anecdotally, I'd say the only things that would make a clearly noticeable performance difference to a layperson or casual computer user from the last few years would be: 1.

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.

Wouldn't newer ones be more power-efficient as compared to the older one? I remember reading a post on HN which stated the OP buying older, high spec hardware for cheaper than latest one and almost all comments pointed to power-efficient thing

Newer processors do the same amount of work faster using multiple cores, so they burn same amount of energy in shorter period of time.

But newer processors use less power at idle, and doing work faster means it can spend more time at that idle, low-power state.

Since I'm not a gamer or CPU-news-watcher, would anyone be able to put this in context?

Is this:

-- a major improvement in power efficiency, heat?

-- major gain in speed (and who is the consumer concerned with this)

Seems like everyone is more concerned with GPU capability as the bottleneck for whatever application these days.

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.

Yes, he said the only thing he really noticed is that his build time dropped by a double digit percent but not a triple digit percent. He'd bought top of the line specs each time and had maxed out the ram and processor bin.

And now there's a new category.

4. If they previously had an early generation of Core CPU like a Sandy Bridge that suffered great performance hit due to vulnerability, and then moved to an Ice Lake, or better, an AMD...
