Even used they sell old CPUs delidded at such high prices that a lot of times we can now buy something much newer and better for the same price sadly...

They can probably get much higher yields through forcing us to run lower voltage. That could partly be why they did.

[@SamanthaVimes177]

My theory is that the IHS was kept super thick for 3D V-Cache yields. IIRC AMD was having lower than desired yields on the lapping process to make the 5800X3D because they had to make it so thin to fit the existing socket specifications. So I think the thick IHS might just be extra thick to give them more room to play with when tuning tolerances and yields for next gen 3D stacked CPUs.

[@Nunkuruji]

Thinking the same thing. Though still curious how much further the cpu can go with the extra thermal headroom.

[@pr0xZen]

*der8auer!* If making these bare-die kits, please consider including a _closed (!)_ cell foam "frame" with edge adhesive to install around the dies, to form a sealed barrier between the die and IHS when using liquid metal TIM. Make sure thrøe foam selected can tolerate the heat exposure. Without the IHS there to form a closed cavity, and most users having their MB mounted vertically inside a case - the risk of some LM escaping and shorting something is much greater. Still a somewhat minor risk, but now very much increased, the resulting damage can be very expensive, and this risk can be mitigated without much added work or cost if done at (your) series production level.

I think that at least for enthusiasts they should make a delidded version, for years back in the early 2000s many cpus didnt come with an ihs (granted, this also ended with many cpus dying from chipped or cracked dies).

only issue i had with the 3950x or from an "upgrade" standpoint was ccx and per ccx cache, zen3 was quite the leap since they did away with ccx and brought upon the zencore/integration of a shared cache pool and simultaneous access/computing/ipc from core to cache vs the ccx design which led to voltage jumps/clock bouncing/spikes ultimately latency issues based on those characteristics. Which even the 5950x SHOWS compared to a voltage tightened/OC 5800x or 5900x by comparison which run games better 5800x>5900x even in some cases where scheduling becomes an issue with less than optimized engines/games FC6 being a more recent example.....BC MY FC6 Came free with my 5900x was delayed 1 year from launch....and yet UBISOFT/AMD lobby yields a scheduling issue for r9 cpus in the FC5-FC6 "MADE FOR RYZEN" franchise....granted 12900k also sees the same issue. Also owning a 3950x led to clock tuner ryzen, Dram calculator, ryzen master being used as well as switching things like SMT off for games like escape from tarkov, cs:go, valorant, siege....among others. Which constituted reboots etc forgetting which setting is enabled for which use/case etc. Looking up your board/bios to see which ryzen power profile is most ideal for your specific build bc its non specific and even bios updates could mean you have to switch power profiles to sustain original OCS/stability or lead to crashes which is a nice ADDITION of work load on a random day

With how thick the IHS is, I think you could get a lot of improvement without delidding by just shaving down the IHS and then lapping it flat. You could make a nice kit with a 2-step lapping kit and blocks along with some shortened mounting hardware. Step1: Insert CPU into "tall" guide block. Step2: Use the coarse portion of the lapping block to quickly grind away a good portion of the IHS thickness. The tall block will bottom out on the plate and stop you from grinding down too far. Step3: Insert the CPU into the "short" guide block. Step4: Use the fine portion of the lapping block to get a flat finish on the new top surface of the IHS. The block should again bottom out to prevent you from going through the IHS completely.

Awesome to see day 1 de-lid and direct die cooling videos 😂 A wild guess on the thick IHS, maybe they’re planning for future SKUs (Zen 5 or Zen 6?) with thicker dies, either with 3D V-Cache, or possibly even stacked cores

[@YouCanHasAccount]

They could go for a thicker substrate as well when the z-space is not needed. Don't know what that does to the manufacturing cost but it's good that the platform literally has room to grow.

[@DigitalJedi]

My personal hope is for some Xilinx chiplets to find their way into these chips. They might end up needing that extra Z-height for thicker dies or linking the CPU chiplets with something like the Infinity Fabric in the GPUs.

[@orangepacker7479]

v-cache didn't make the 5800x3d's dies any thicker... I have hope for zen 5 and 6 though. Stacked cores would mean getting threadripper core counts on consumer chips, which would eat into their HEDT market share, so we propably won't see expanded core counts until at the earliest zen 6. My guess is they will use their zen 5c (the c stands for cloud btw) cores on their HEDTS for zen 5 to experiment and then bump the core counts for consumer chips at zen 6.

Wow 20° is kinda nuts, maybe they should have just went with new cooler mounts and shaved down that IHS 1mm.

[@agoogleuser2369]

Kids asking for AMD to sell delidded chips are too young to remember the time when Intel and AMD all did it. It was stressful having to be extremely careful not to chip the edges of the die. Companies like Thermaltake used to sell thin copper shims to place in between the CPU and the heavy copper heat sink. I'm glad those days are long behind us now. The cooler bracket and plastic mounting points off the CPU socket were outrageous too. I remember the time when CPU coolers were mounted directly to the CPU socket. There were no 4 bolts or latches around the CPU socket to mount the CPU cooler like we've had for decades. One time I ended chipping off the edges of the brittle mounting points off the white plastic CPU socket (Socket A) when installing a new Athlon XP CPU. That mistake almost ruined my motherboard. There were no metal CPU brackets like we have today. Thank you Intel and AMD for fixing these design problems.

[@teemu3370]

Lost my Barton to cracked die..... Might still have it....

[@eventslooped]

Athlon Thunderbird good memories

[@tiagomnm]

It is also possible the IHS is also thicker to compensate the lack of all around, IHS mounting support. Either way, this is probably ok if it is sacrificing overclocking but making it easier for most users to upgrade. These are already at insane amounts of power and extreme OC users can go the extra mile.

[@Strykenine]

Roman, I was wondering if you were running the 7950X or the 7900X? It seems like you are running the 7900X since you have 12 cores, but the charts @ 18:50 indicate a 7950X. Thanks for this - I may try my first delid with one of these chips.

Awesome video! After watching your analysis, I agree that AMD should have ditched the cooler compatibility, it's just going to add unnecessary confusion for the few people that really want to use their old AM4 cooler on AM5... Well, it looks like my EK AIO should fit, but I'm very interested in going the delided + open loop route on the next go around (soft tubes so I can swap parts) tho that's not goinna be anytime soon- I'm absolutely thrilled with my AM4 system, it does everything I can throw at it with plenty of headroom.

[@orangepacker7479]

Unfortunately there a lot of people who just want it to work immediately, and AMD can't ignore them to make those who are more knowledgeable happy

[@majed1000000]

The thick IHS is because they’re planning for the next Ryzen 8000 with thicker dies that use 3D V-Cache to be compatible with AM5.

Can you do a video on ihs lapping and how that would affect cooler compatibility? And by lapping I mean getting rid of that extra 1.2mm or so of thickness. Not everyone is comfortable with delidding, but if there was a way to reduce the ihs thickness and use an adapter or something for the coolers to maintain the proper mounting pressure, I think that would be beneficial to a larger percentage of am5 owners

Derbauer, do you have any idea of how much z height difference there will be between the 3D Vcache and straight dies? More importantly, could the excess height/thickness of the IHS be partially designed there with the idea of future growth space? Could the implementation of the cache on top reduce the IHS thickness from 2mm down to a more common 1.5 mm?

@@MarcABrown-tt1fp You buy a completed GPU so the die is coming with a heat spreader, aka the cooling solution. Few people open up their GPUs. The CPU is sold but itself, the heat spreader is the only protection from damage. It is not cost effective to warranty more than 5% of a product and without the heat spreader it would be more likely to be about 15% warrantied.
