Do CPUs get partially disabled like a GPU?

[Upgrayedd]

they all do it.

I understand that. But which dies are the full ones and what are their cut parts. Im looking for a list. I already know chips get binned but I want specifics of what CPUs get binned from what dies.

Everything that is not the top model of its lineup, is binned. Anything with reduced shaders, core count, cache, etc, has had hardware disabled or cut.

Hell, they can design this hardware with extra parts knowing some will fail and when testing shows theres no need any more, easy product improvement like the nvidia supers with higher shader count

(So a theoretical GPU could have 1000 shaders with an average of 960 working. They could decide to play it safe and sell the product with 950 enabled, until they perfect them process and the average is 990 working - so they suddenly sell a 2nd gen product with 980)

See with that wording you make it sound like all RTX gpus are binned from the TU102. I just want to know CPU die names and all models that are cut from full dies. All the models cut from the 9900K then what would be the next lowest full die model. etc etc. I understand binning...

 

[Mussels]

It was a simplified example. No one can easily give you such a list as what you're asking for, because the companies dont make that information public - all we've got are educated guesses really.

I haven't looked up Intel reviews in a long time (who xan blame me. they're uninteresting af) when i7s were 4c8t all i3, i5 and i7 (normal not HEDT) were same 4 core die.

And since current 4 core i3 9100 to 8 core i7 9900k can be run on the same platform if motherboards it's reasonable to assume they use the same die.

Why's that interesting? You'd need some Intel people for such a list.

I think I saw somewhere that someone delidded the current generation and found Intel is making an 8-core die and a smaller 4 core die for the lower end processors.

Tomorrow you guys are going to see one of the most extreme... cases of silicon size to resources used in it ratio in some products. Not consumer stuff.

Brings back memory's of Intel's PAST proposed Scheme of

Brings back memory's of Intel's PAST proposed Scheme of
PAY TO UNLOCK CPU FEATURES

Ah yes, the buy a Pentium then later pay a small extra fee to unlock through Intel's firmware software HyperThreading, some extra L3 Cache, and a clockspeed bump. I think it was though a Celeron that unlocked into a Pentium.

Edit: Guess I was wrong, it wasn't a $20 USD extra fee but $50.00 to unlock the CPU.

Hold onto your hyperthreaded horses, because this is liable to whip up an angry mob -- Intel's asking customers to pay extra if they want the full power of their store-bought silicon. An eagle-eyed Engadget reader was surfing the Best Buy shelves when he noticed this $50 card -- and sure enough, Intel websites confirm -- that it lets you download software to unlock extra threads and cache on the new Pentium G6951 processor.

This isn't exactly an unprecedented move, as chip companies routinely sell hardware-locked chips all the time in a process known as binning, but there they have a simpler excuse -- binned chips are typically sold with cores or cache locked because that part of their silicon turned out defective after printing. This new idea is more akin to video games that let you "download" extra weapons and features, when those features were on the disc all along.

Intel wants to charge $50 to unlock stuff your CPU can already do

hmmm that makes more sense economically tbh. Now I have confusion about 8000 series. Were thay native 6 core dies or 8 core dies disabled?

 

[biffzinker]

Were thay native 6 core dies or 8 core dies disabled?

Yes, actual six then eight cores per die

Ring Bus from four to six, and eight cores a silicon die for desktop while Xeon was Ring Bus up to twenty four cores on a die then moved to a Mesh Network interconnect between dies.

Xeon

Later Xeon

depending on the microcode in your bios some features like overclocking can be enabled but it's normally not worth it since it can cause other bugs like the temperature sensor not working. that said you can mod a z170 board to run upto a i9-9900k if you wanted with no major issues besides the difficult setup.

 

[discopanda]

Thanks for the purchasing advice everyone but I'm just here to learn lol

So all HEDT Intel cpus are cut from the same die. Interesting.

Still am trying to figure out exactly which dies are full dies and how far down their disabled parts go until a smaller die is used or something. Thanks everyone for the input so far.

The HEDTs are all based on the 18-core HCC (High Core Count) silicon for the Xeon line with disabled memory channels to limit them to 128 GB. The client models consist of an 8-core die (HT enabled for i9, disabled for i7), a 6-core die, and a 4-core die. The core design is identical across the client chips, so the HT hardware is disabled for i5s and i3s.

For AMD, the 3700X and 3800X have a fully-enabled 8-core die, the 3900X is two dies with 2 cores disabled in each.

 

[GoldenX]

Then there's the Zen APUs that are so far a single full CCX, with the Athlon APUs being cut down versions of those. Let's see whet they do with the Zen 2 ones.

 

[discopanda]

Yes, the 3400G is one fully-enabled 2nd gen Zen 4-core CCX + Vega, the 3200G has HT and some of the graphics silicon disabled. Athlon is still using the original Zen architecture and is a cut-down 2400G.

 

[R0H1T]

Nope, Intel has 3 dies for HEDT - LCC, HCC, XCC.

XCC is only used for W3175x IIRC.

 

[discopanda]

No, LCC (10-core), HCC (18-core), and XCC (28-core) are for Xeon. All HEDTs are from the HCC die.

 

[R0H1T]

You say that, yet this is what I remember. Any updates after this, because I don't recall this being changed recently?

The first half of the Skylake-X processor llineup follows this trend. Intel will launch four Skylake-X processors based on the LCC die, which for this platform will have a maximum of 12 cores. All processors will have hyperthreading.

[discopanda]

I'm referring only to the current-gen HEDT chips, not the 7xxxX chips

 

[R0H1T]

Yes & that's what I'm asking, where did you see the updated info. Any source for that?

 

[discopanda]

https://en.wikichip.org/wiki/intel/microarchitectures/skylake_(server)

 

[R0H1T]

And where does it say that all HEDT chips use HCC now

 

[discopanda]

You're right, the 98xxX use LCC, the 99xxX use HCC. Actually they're all HCC since even the 98xxX have 12 sets of L3 cache.

I looked into it a bit more and Anandtech came to the same conclusion - "it would appear that every processor is from the HCC family. We can see this because of the cache sizes."

A full die is the largest core count Xeon and the Largest For AMD is an Epyc/Threadripper
