Intel Core i9-10900K der8auer De-Lidding Reveals Accurate Die-Size Measurements
Professional overclocker and extreme cooling products developer der8auer de-lidded a Core i9-10900K 10-core processor to study the processor's behavior with various kinds of custom cooling setups. It was discovered that the 10-core "Comet Lake" die measures 206.1 mm² in die-area. It is 9.2 mm wide like its predecessors, "Coffee Lake" 8-core, 6-core, and 4-core, but is 22.4 mm long, with the outer edges of its packaging material barely within a couple of millimeters of the adhesion point of the integrated heatspreader (IHS). Given what we know about how much each pair of cores adds to these dies, we predict that Intel cannot elongate this die to 12 cores, without having to remove the iGPU. der8auer discovered that using liquid metal TIMs and running the processor de-lidded shaves up to 7 °C off temperatures.

You brought up cost as a straw man when I was talking about lack of 16-core competition from Intel on S1200 because they've run out of physical space on the package for more cores.
Even though you shifted to your 'cost' straw man whilst changing platform altogether I gave you two AMD chips (2920X and 2950X) that compete with your straw man argument at those costs.
What is the point you're trying to make in this thread about S1200 Comet-Lake die size?
That an HEDT processor on S2066 is comparable....?
Please get a grip and stay on topic rather than throwing (incorrect) accusations and straw man arguments.
Intel S1200 processors on 14nm have reached the maximum die length they can without changing architecture. The uncore/ring is a central spine to keep it as short and low-latency as possible The only way Intel could add more cores without drastically altering the architecture is to ditch the IGP just to make room on the end. As it stands, Comet Lake almost touches the sizes of the IHS it's so long; There is no physical room to add more cores on a longer die without dumping the IGP, or switching to a smaller node, which at the moment means Intel's dumpster-fire 10nm disaster.
My 2600X I had to buy a discrete GPU which annoyed me as only used on a ESXi machine, no need for a discrete GPU. Then after I put in the GTX 1030, it still annoyed me as I know if there was a iGPU the 1030 could be used for passthru (with proxmox).
When I build intel machines I can test using the iGPU, and some of my customers had iGPU as their configuration preference. They needed lots of CPU power but not GPU.
To me once you hit 4-6 cores the typical end user wont benefit much and once you hit 8 cores, any more on top of that is niche.
Compiling
Encoding
Virtualisation
Those 3 use cases in the grand scheme of things are very uncommon.
If you want to stream and game on a single cpu I think 8/16 is good enough, but if the game is particularly demanding one could argue more core's would help in that, but again the amount of professional streamers within the overall consumer market is tiny. Intel know more than us what consumers typically do.
It gets overhyped because youtube reviewers and twitch streamers have a large influence, both of these sets of people have needs to encode so they push the "more cores" mantra as they personally benefit, they do over emphasise it as 97% of consumers do not encode/compile stuff.
This is why bulldozer failed, it was a cpu built for geeks who love core count, but it wasnt good for the average consumer.
The fact cinebench is the go to benchmark for most of the media is misleading people as well, as that is an encoding benchmark, something like geekbench is more accurate as it tests many different cpu functions, not just encoding.
The Ryzen 7 4700G is pretty much exactly what you just said - 8C/16T and a Vega IGP with 7 compute units (448 shaders)
Also to add to my previous comment, if I could choose between e.g. 8 core 5.3ghz and 10 core 4.8ghz, the 5.3 ghz wins.
You can't quite find them on store shelves yet, but the 4700G is already beyond rumour stage and performance is going to match or beat the Ryzen 9 4900HS because it'll be the same product in a desktop socket with access to a larger power budget (65W nominal like the 3700X, but we all know that PBO+ means that they'll suck down almost 90W at boost clocks).
"The 8-core/16-thread CPU of the Ryzen 7 4700G has a nominal clock speed of 3.60 GHz, and a maximum boost frequency of 4.45 GHz"
That was 2 weeks ago and it's a final version product, not an engineering sample.
