Intel Core Ultra 400HX "Nova Lake" Mobile Processor Core Configurations Surface

Intel's next-generation mobile processor for gaming notebooks and portable workstations, the Core Ultra Series 4 "Nova Lake-HX," will come in two distinct core configurations, according to a leak by Jaykihn, a reliable source for Intel leaks. "Nova Lake-HX" is segmented from the mainstream "Nova Lake-H" with a wider I/O that supports configurations with discrete GPUs. The top-of-the-line "Nova Lake-HX" processor will come with a CPU core configuration of 8P+16E+4LPE, that's eight "Coyote Cove" P-cores, and 16 "Arctic Wolf" E-cores, both of which are upgrades over the current "Cougar Cove" and "Darkmont" core architectures, respectively. The Compute tile features 8P+16E cores sharing an L3 cache, while the chip's 4 low-power island E-cores, also based on "Arctic Wolf," will be located in the SoC tile.

Intel is also planning a performance-segment "Nova Lake-HX" core configuration, with 6P+8E+4LPE under the hood. This will likely reuse the 6P+8E Compute tile from the mainstream "Nova Lake-H" processor, but with the SoC + I/O tiles Intel plans to use for the "Nova Lake-HX". This would give the chip a maximum core count of 6P+8E+4LPE. Perhaps the most interesting aspect of both these chip types is the iGPU, and its Graphics tile will be the tiniest variant in the series, with just 2 Xe cores. The iGPU of "Nova Lake" family is based on the Xe4 "Druid" graphics architecture. These chips feature a basic iGPU because they are expected to come with a full fat PCI-Express 5.0 PEG interface for discrete GPUs, and ideally you'd want the iGPU to be as small as possible.

Just using random numbers I see.

Should be 300 too no?

I believe 300 is Panther Lake only. But that would mean no 300 serie for Desktop or Nova Lake will be both 300 serie for desktop and 400 for mobile. kinda strange but we're used to incoherent naming from cpu company in the past 6 years...

So, have they just like entirely abandoned the desktop and will now just be making Core Ultra 270 Plus Plus Plus Plus instead or something? Already talking about 400 series and we haven't even got 300 yet. Except laptops. Everything laptops! I don't get it.

RejZoREverything laptops! I don't get it.
Let me help:
  • OEM channels only.
  • Volume-ordering trays only.
  • Min. Order of 1k unit trays.
  • Pre-orders agreed with at least a years' notice.
  • No shelf packaging needed.
  • No major marketing needed.
  • No major logistics for delivering to the whole globe.
  • No price negotioation with N amount of retailers.
Basically, it's the way of the less hasle to sell a processor for either Intel or AMD.

vbq7qK68eyYAH4iR300 was used. From Yesterday
www.techpowerup.com/347913/intel-wildcat-lake-core-300-series-specifications-surface
yeah panther lake and wildcat lake are both 300. wildcat lake being i think a replacement for the intel n line.
but arrow lake and lunar lake are both 200
So it kinda stands to reason nova lake for mobile will be 300 as wel not 400.

I'm of the opinion intel needs to redo their whole product naming scheme and dump the whole core, core ultra BS
and go back to calling it 80x86 so 80(22)86 for nova lake

_JP_No price negotioation with N amount of retailers.
There are a few OEMs with bargaining power against INTC, but among retailers, AMZN is probably the only one.
I agree with your other points, and you even left out the most important one: most PCs sold are not desktops and most desktops sold are not DIY.

Makes sense to me. Core Ultra 100 was mobile only (with a focus on efficiency), Core Ultra 200 was desktop + high-performance mobile, Core Ultra 300 is mobile-only (with a focus on efficiency), Core Ultra 400 will be desktop + high-performance mobile. Is it intuitive? No. Is it consistent? Yes.

Does it sound like tick-tock? Yes, it does.

Really wonder about the clock speeds from both AMD and Intel for Zen 6 and Nova Lake respectively. Seen lots of rumors from Zen 6, but nothing like an actual benchmark. Meanwhile, Nova Lake clock speeds are a complete mystery. Unlikely Intel will lower clocks though, so we may see 6-6.2 GHz and similar from AMD.

Clock speeds have become significantly less important lately, for a few reasons. For AMD, the Infinity Fabric imposes limitations on memory speed and CPU scheduling, which leads to results like the 9900X having worse gaming performance than the slower 9700X. For Intel, why bother squeezing an extra 0.2 Ghz out of a P core, when you could instead spend that power budget on 4 additional E cores? That also gives Intel the freedom to invest in architectural improvements that don't facilitate or work well with higher clock speeds. It's no longer about how fast your CPU can cycle, but how much it can do within a cycle.

Why does Core Ultra 100 need to be in sync with Core Ultra 700 many generations down the line?? Tech is changing all the time as well as demand and the economy. Any manufacture should be able to define what the next product number means in a line of product numbers any way they see fit. No idea why so many are so pedantic about these things!! The biggest dtermination should be price/performance.

Huh? A consistent naming scheme is very important for branding. I'm not sure what you're talking about. The name of the product doesn't limit your ability to buy it or examine price/performance.
