Intel's upcoming 11th Generation Core "Tiger Lake" processors introduce the company's first major refinement of its 10 nanometer silicon fabrication node, dubbed 10 nm+. The node introduces two key features that work to improve the power characteristics of the silicon, allowing Intel to yield more performance without raising power/thermals over the previous generation. VideoCardz scored a major scoop on 10 nm+, including the introduction of the new SuperFin transistor, and SuperMIM capacitor.

SuperFin is a redesigned FinFET, a nanoscale transistor, which offers increased gate pitch, yielding higher drive current, improved channel mobility, and an improved source/drain, yielding in lower resistance. The other key component of 10 nm+ is SuperMIM, delivering a 5 times increase in metal-insulator-metal capacitance. Intel is yet to put out energy efficiency gain numbers for the process, but promises a "dramatic increase in frequency" over the previous generation, which lines up with leaks of the Core i7-1185G7 shipping with significantly higher clock speeds.



In related news, the "Willow Cove" CPU cores powering "Tiger Lake" reportedly features 1280 KB of L2 cache per core, a dramatic increase over the 512 KB of the "Sunny Cove" core, and 256 KB of the "Skylake" core (in ringbus-based dies). It also features a host of silicon level hardening against return/jump-based side-channel attacks. Its integrated memory controller supports LPDDR5-5400, LPDDR4X-4767, and dual-channel DDR4-3200 memory. The top trim of the Xe Gen12 iGPU solution features 96 execution units, and a dedicated 3840 KB L3 cache.

Intel technology chief architect and SVP Raja Koduri is expected to detail all of the innovations that go into "Tiger Lake," at a virtual press-event on August 13.

Pluses may or may not be completely gone from future branding and PR btw. Intel may or may not be fed up with people pointing at a long line of pluses and laugh.

That's a ridiculous amount of L2 cache, these are rather desperate measures to claw back some performance in synthetic tests. Plus caches are expensive and consume a lot of power, both of which are undesirable traits in a mobile chip. And they claim more clock speed, which means even more power consumption.

Speculation based on months of these rumours: Willow Cove is designed to handle variable amounts of cache. Higher-end and desktop SKUs will get more, mobile parts less. The values quoted would likely represent the highest-end configuration (HEDT/server).

And bigger caches are not just for show or benchmark, they're critical for preventing trips to main memory, which is one of the major factors in CPU performance. They are definitely going to be expensive though (in terms of cost, heat, power, and die area).

Bigger caches are worth it only when the access pastern is sequential/regular. That happens a lot in synthetic tests, in real world applications though not as much. A desktop Ryzen chip has what, almost 70mb in total of cache ? Doesn't make that much of a difference.

Nothing new for the cache. My Cascade Lake-X has 1024MB L2 per core. Idk if matthers tho.

It does help quite a bit in games too since it minimizes the cache miss delays to an extent. There is definitely a point of diminishing returns though.

We're still like 2-3 years away from seeing 10nm CPUs in mainstream. And they started talking about 10nm+ already.

That's a ridiculous amount of L2 cache, these are rather desperate measures to claw back some performance in synthetic tests. Plus caches are expensive and consume a lot of power, both of which are undesirable traits in a mobile chip.
Larger caches improve several aspects of performance, not only limited to cache misses etc. It also helps data intensive AVX workloads like video encoding.
I don't believe caches use that much power compared to ALUs, FPUs, etc.

If it yields a reasonable performance increase for the die space and other trade-offs, then I'm all for it, no matter how "desperate" you think it is.

Bigger caches are worth it only when the access pastern is sequential/regular. That happens a lot in synthetic tests, in real world applications though not as much. A desktop Ryzen chip has what, almost 70mb in total of cache ? Doesn't make that much of a difference.
There is a huge difference between L2 and L3 cache in access patterns. L3 cache is also a overflow cache, while the prefetcher feeds into L2, and each cache line in L2 is probably >10x as "useful" as each one in L3.

Cache is also a lot more than just size, there is latency, associativity, bandwidth etc.

Yet more Lake yadayada and yet no product on shelves.
Ice Lake-U is shipping in large quantities. Tiger Lake will too.

As I suspected. One the areas where people have been pointing to in support of the argument Intel 10nm = TSMC 7nm is gate pitch. If 10nm+ increases gate pitch to support more drive current (hence faster switching), then effectively Intel are trading density for performance. Which is fine, but underscores that a workable, high performance Intel 10nm process is more like TSMC 10nm and that they are further behind TSMC than previously thought. This is what Intel have been doing with 14nm revisions to eek more clock speed as well, which is why those process comparisons have always been BS.

Cache is expensive in terms of die size and power consumption. When Intel is more than doubling cache and including very capable iGPUs you know the day as come where competition exists.

Having said all that the Tiger Lake CPUs look really good with that healthy IPC lift.

Does Intel maths mean that 10+1=11?
Intel 10nm = TSMC 7nm
Intel 10nm+ = Intel 11nm = TSMC 8nm

I observed an increasing usage of the word Super of late. I wonder what is so super about it. Till we see the end product, this remains another marketing gimmick in my opinion. Good thing they did not call this AvengersFin and AvengersMIM.

oddly amd does the same, but the fan boys dont bitch, but those same people like to complain about intel like little brats. its infantile.
