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.

Same base block argument. At 25W, the i7-10710U has a base clock at 1.6GHz, the newer parts are at 3.0GHz at 28W.

For laptops (which are far more likely to thermal throttle), this is a huge deal.

I did a similar shift. I would say the new one is quite a bit faster.

And much hotter! I’m happy with the purchase but sometimes the machine gets so hot I can barely use it.

True but there is no denying that it is a much faster machine.

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.

I wonder what a triple digit percent drop would feel like...

Time loop logic? I guess that would just about make it into the triple digits :) https://en.wikipedia.org/wiki/Novikov_self-consistency_princ...

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.

1080p outright looks blurry after using 4k, so its pretty hard to even contemplate going back

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,…

I'd say the same thing about upgrading from an i7-6800K (2016 Broadwell-E) to a Threadripper 3960X. Barely a difference (my main work is a ~250k loc c# solution, also a similar medium-ish sized Angular app).

The whole point of bitmap fonts is that they're designed to be used without anti-aliasing. There's no blur.

Examples:

If you're on 4K you can simulate how they look on 1080p with 2x integer nearest neighbor scaling.

Maybe your build systems work incrementally or otherwise don’t use 4x the cores? A Ryzen with the higher clock speed might have been a better choice.

> Native Thunderbolt A nice tweak sure but also irrelevant as a consumer. It just results in one less component on the motherboard, it doesn't change any functionality. > much faster clock speeds Relative to what? Last year's 4c/8t 14nm i7-10510U has a higher boost frequency than any of the chips announced today, and it's also a 15 W TDP CPU. The 4c/8t i7-1185G7's 3ghz base frequency is nice I guess but barely higher…

Thunderbolt being a built-in freebie rather than requiring a fairly large and expensive separate controller means it might start showing up in mid-range PCs rather than being a niche professional/high-end feature, which in turn increases the market size for Thunderbolt peripherals.

Its probably only the PHY for it and require additional (expensive) components to implement, just like with the "integrated" 2.5 Ghz.

I'm talking about this image: https://images.anandtech.com/doci/16063/474551355-Intel-Blue... I don't see any coherent fabric blocks — what looks like large cache sections to my eyes are entirely inside the "Core" blocks. Maybe they're just not drawn correctly. Here are some much older i7s, for example: https://www.cs.uaf.edu/2009/fall/cs441/proj1/russell/images/... https://www.notebookcheck.net/fileadmin/_migrated/p…

The labeling on that image is... approximate. You can see the orange L3 blocks inside the area labeled as cores and it's still shared.

> it's still shared

Right, that was really my main question: besides the labeling (which is of course approximate), the positioning sure looks like each core would have its own "favorite" section of the cache. And being shared, it seems like this could make for some interesting performance behaviors.

Ah, interesting, this topology was introduced with Sandy Bridge. I'm just out of date: https://www.anandtech.com/show/3922/intels-sandy-bridge-arch...
